SUMMARY RISK FACTORS

Our business is subject to a number of risks of which you should be aware in evaluating our company and our business. These risks are discussed 

more fully in the “Risk Factors” section of this Annual Report on Form 10-K for the year ended December 31, 2023. These risks include the following:

Risks Related to Our Business

•

Our  business  is  highly  dependent  on  the  success  of  our  product  candidates,  LTI-03  and  LTI-01  and  any  other  product  candidates  that  we 
advance into clinical development. Our approach to drug research and development in the area of fibrotic diseases, with a focus on Cav1-
related  peptides,  is  unproven  and  may  not  result  in  marketable  products.  All  of  our  product  candidates  will  require  significant  additional 
development before we may be able to seek regulatory approval for and launch a product commercially. Raising additional capital may cause 
dilution to our stockholders, restrict our operations or require us to relinquish rights to LTI-03, LTI-01, or other product candidates.

Risks Related to Our Financial Condition

•

•

•

•

•

We  will  require  substantial  additional  capital  to  finance  our  operations.  Our  cash  and  cash  equivalents  are  not  sufficient  to  enable  us  to 
complete the development and commercialization of LTI-03 and LTI-01. If we are unable to raise such capital when needed, or on acceptable 
terms,  we  may  be  forced  to  delay,  reduce  and/or  eliminate  one  or  more  of  our  clinical  and  research  and  development  programs,  future 
commercialization efforts or other operations.

There is no guarantee that our acquisition of Lung and its business will increase stockholder value in our company or that we will be able to 
realize the anticipated benefits of the acquisition.

We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in 
the future or fail to maintain an effective system of internal control over financial reporting, which may result in material misstatements of 
our financial statements or cause us to fail to meet our periodic reporting obligations.

We have incurred significant net losses since inception and we expect to continue to incur significant net losses for the foreseeable future and 
do not expect to achieve or maintain profitability. Even if we are able to develop and commercialize our product candidates, we may never 
generate revenues that are significant or large enough to achieve profitability.

We have identified conditions that raise substantial doubt about our ability to continue as a going concern.

2

 
 
 
Risks Related to the Discovery, Development and Commercialization of Product Candidates

•

•

•

•

The  outcome  of  preclinical  testing  and  early  clinical  trials  may  not  be  predictive  of  the  success  of  later  clinical  trials,  interim  results  of  a 
clinical trial, do not necessarily predict final results and the results of our clinical trials may not satisfy the requirements of the U.S. Food and 
Drug Administration, or the FDA, or comparable foreign regulatory authorities.

We  may  incur  additional  costs  or  experience  delays  in  completing,  or  ultimately  be  unable  to  complete,  the  development  and 
commercialization of LTI-03, LTI-01 or any other product candidates.

Our ongoing and future clinical trials may reveal significant adverse events or unexpected drug-drug interactions not seen in our preclinical 
studies or earlier clinical studies and may result in a safety profile that could delay or prevent regulatory approval or market acceptance of 
any of our product candidates.

Clinical development involves a lengthy, complex and expensive process, with an uncertain outcome.

Risks Related to Marketing Approval, Reimbursement, Healthcare Regulations and Ongoing Regulatory Compliance

•

•

•

•

We  have  never  obtained  marketing  approval  for  a  product  candidate  and  we  may  be  unable  to  obtain,  or  may  be  delayed  in  obtaining, 
marketing approval for any product candidate. If we are unable to establish marketing and sales capabilities or enter into agreements with 
third parties to market and sell our products, we may not be able to generate product revenue. 

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time-consuming and 
uncertain and may prevent us, or any future collaborators, from obtaining approvals for the commercialization of LTI-03, LTI-01 or any other 
product candidate that we may develop. As a result, we cannot predict when or if, and in which territories or for which indications, we, or any 
future collaborators, will obtain marketing approval to commercialize LTI-03, LTI-01 or any other product candidate that we may develop.

Even if a product candidate we develop receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, 
patients, third-party payors and others in the medical community necessary for commercial success.

Even  if  we  receive  regulatory  approval  of  any  product  candidates,  we  will  be  subject  to  ongoing  regulatory  obligations  and  continued 
regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory 
requirements or experience unanticipated problems with our product candidates, if approved.

Risks Related to Our Dependence on Third Parties

•

•

•

We rely on third parties to conduct certain aspects of our clinical trials and preclinical studies. If these third parties do not successfully carry 
out  their  contractual  duties,  meet  expected  deadlines  or  comply  with  regulatory  requirements,  we  may  not  be  able  to  obtain  regulatory 
approval of or commercialize any potential product candidates.

Because  we  rely  on  third-party  manufacturing  and  supply  vendors,  our  supply  of  research  and  development,  preclinical  and  clinical
development materials may become limited or interrupted or may not be of satisfactory quantity or quality.

We have entered into a collaboration agreement with Taiho Pharmaceutical Co., Ltd., or Taiho, for the development of LTI-01 and may in the 
future seek to enter into collaborations with third parties for the development and commercialization of other product candidates. If we fail to 
enter  into  such  collaborations,  or  our  collaborations  are  not  successful,  we  may  be  unable  to  continue  development  of  such  product 
candidates, we would not receive any contemplated milestone payments or royalties, and we could fail to capitalize on the market potential of 
such product candidates.

Risks Related to Our Intellectual Property

3

 
 
•

•

Our success depends in part on our ability to protect our intellectual property. It is difficult and costly to protect our proprietary rights and 
technology, and we may not be able to ensure their protection. 

We are currently party to license or other collaboration agreements that impose certain obligations on us, and we may enter into additional 
license or collaboration agreements in the future. If we fail to comply with our obligations under such present or future agreements with third 
parties, we could lose license rights that may be important to our business.

Risks Related to Our Common Stock

•

•

If  we  fail  to  maintain  compliance  with  the  requirements  for  continued  listing  on  the  Nasdaq  Capital  Market,  our  common  stock  could  be 
delisted from trading, which would adversely affect the liquidity of our common stock. 

Assuming  the  conversion  of  all  outstanding  Series  X  Non-Voting  Convertible  Preferred  Stock,  or  the  Series  X  Preferred  Stock,  and  the 
exercise  of  outstanding  warrants  to  purchase  shares  of  our  common  stock,  or  the  Warrants,  there  is  a  concentration  of  ownership  of  our 
outstanding common stock by one group of affiliated stockholders. If this group chooses to act together, it could exert substantial influence 
over our business, and the interests of this group may conflict with those of other stockholders.

Overview and Recent Developments

PART I

Aileron Therapeutics, Inc. (“Aileron,” “we,” “us,” “our,” or the “Company”) is a clinical stage biopharmaceutical company focused on developing 
novel therapies for the treatment of orphan pulmonary and fibrosis indications with no approved or limited effective treatments. We currently have two 
product candidates in clinical development, LTI-03 and LTI-01, and multiple candidates in preclinical development focused on fibrosis indications. Our 
pipeline includes: 

•

•

•

LTI-03,  a  peptide,  for  which  we  are  currently  recruiting  patients  for  a  Phase  1b  dose-ranging,  placebo-controlled  safety,  tolerability,  and 
pharmacodynamic biomarker activity trial in development for the treatment of idiopathic pulmonary fibrosis, or IPF, that has demonstrated 
the ability to protect healthy lung epithelial cells and reduce pro-fibrotic signaling; 

LTI-01,  a  proenzyme  that  completed  a  Phase  2a  dose-ranging,  placebo-controlled  trial  and  a  Phase  1b  safety,  tolerability  and  proof  of 
mechanism trial in loculated pleural effusion, or LPE, patients, an indication that has no approved drug treatment; and 

preclinical programs targeting cystic fibrosis and a peptide program focused on the Cav1 protein for systemic fibrosis indications.

Prior to the termination of development of our main product candidate in February 2023 and the acquisition of Lung Therapeutics, Inc. (as described 
below), our focus was the development of our main product candidate, ALRN-6924, a MDM2/MDMX dual inhibitor that leveraged our proprietary peptide 
drug technology. Since our inception, we have devoted a substantial portion of our resources to developing our product candidates, including ALRN-6924, 
developing our proprietary stabilized cell-permeating peptide platform, building our intellectual property portfolio, business planning, raising capital and 
providing general and administrative support for these operations.

Announcement of Exploration of Strategic Alternatives

In  February  2023,  we  announced  a  review  of  initial  data  from  our  Phase  1b  chemoprotection  trial  of  ALRN-6924  in  patients  with  p53-mutated 
breast  cancer.  Based  on  these  findings,  we  decided  to  terminate  the  Phase  1b  breast  cancer  trial  and  further  development  of  ALRN-6924.    We  also 
announced that we were exploring a range of strategic alternatives to maximize shareholder value. We engaged Ladenburg Thalmann & Co., Inc. to act as a 
strategic advisor for this process. Strategic alternatives that were being evaluated included, but were not limited to, an acquisition, a merger, a business 
combination,  a  sale  of  assets  or  other  transactions.    In  addition,  in  February  2023,  we  determined  to  reduce  our  workforce  from  nine  to  three  full-time 
employees, which we completed in the second quarter of 2023.

The Lung Acquisition

On  October  31,  2023,  we  acquired  Lung  Therapeutics,  Inc.,  or  Lung,  pursuant  to  an  Agreement  and  Plan  of  Merger,  or  the  Lung  Acquisition 
Agreement. Following our acquisition of Lung, or the Lung Acquisition, the business conducted by Lung became the business primarily conducted by the 
Company  and  we  shifted  our  operating  disease  focus  to  advancing  a  pipeline  of  first-in-class  medicines  to  address  significant  unmet  medical  needs  in 
orphan pulmonary and fibrosis indications. 

Under the terms of the Lung Acquisition Agreement, at the closing of the Lung Acquisition, we issued to the stockholders of Lung 344,345 shares 
of our common stock and 19,903 shares of our newly designated Series X Preferred Stock. Each share of Series X Preferred Stock is convertible into 1,000 
shares of common stock.  In addition, we assumed all Lung stock options and all warrants exercisable for Lung common stock immediately outstanding 
prior to the closing of the Lung Acquisition, each subject to adjustment pursuant to the terms of the Lung Acquisition Agreement.

5

 
 
Immediately following the closing of the Lung Acquisition, we entered into a Stock and Warrant Purchase Agreement, or the Purchase Agreement, 
with a group of accredited investors, or the Investors, led by Bio Partners, the majority stockholder of Lung prior to the closing of the Lung Acquisition, 
and  including  Nantahala  Capital,  as  well  as  additional  undisclosed  investors,  pursuant  to  which  we  issued  and  sold  (i)  an  aggregate  of  4,707  shares  of 
Series X Preferred Stock, and (ii) warrants to purchase up to an aggregate of 2,353,500 shares of common stock, or the Warrant Shares, for an aggregate 
purchase price of approximately $18.4 million, which included the conversion of certain convertible promissory notes in the aggregate principal amount of 
approximately $1.6 million issued by Lung to Bios Partners prior to the closing of the Lung Acquisition at a 10% discount to the per share price of the 
Series X Preferred Stock, or the Financing, and collectively with the Lung Acquisition, the Transactions. The Financing closed on November 2, 2023. 

On  February  28,  2024,  we  held  our  2023  annual  meeting  of  stockholders  in  which  our  stockholders  approved  the  issuance,  in  accordance  with 
Nasdaq  Listing  Rule  5635(a),  of  shares  of  common  stock,  upon  conversion  of  our  outstanding  Series  X  Preferred  Stock.  Following  approval  of  the 
conversion of outstanding Series X Preferred Stock, the Company had approximately 29,495,512 shares of common stock issued and outstanding on a pro 
forma basis, which gives effect to the full conversion of the Series X Preferred Stock as of the date of our 2023 annual meeting of stockholders, without 
regard to beneficial ownership limitations that may limit the ability of certain holders of Series X Preferred Stock to convert such shares to common stock 
as  such  time.  On  March  5,  2024,  based  upon  existing  beneficial  ownership  limitations,  12,087  shares  of  Series  X  Preferred  Stock  were  automatically 
converted into 12,087,000 shares of common stock. The remaining approximately 12,523 shares of Series X Preferred Stock (which are convertible into 
12,523,000 shares of common stock) will remain convertible at the option of the holder thereof, subject to certain beneficial ownership limitations.

Principal Product Candidates

LTI-03 

LTI-03 is a novel peptide drug, the sequence of which is derived from the endogenous protein Cav1, that protects lung epithelial cells and inhibits 
multiple pro-fibrotic pathways in IPF patients. IPF is a progressive, fatal, age-associated lung disease with a median survival from diagnosis of two to five 
years. There are approximately 100,000 people living with IPF in the U.S. LTI-03 has been granted Orphan Drug Designation in the U.S. for the treatment 
of IPF. 

The  pathogenesis  of  IPF  is  characterized  by  the  loss  of  healthy  lung  cells  known  as  alveolar  epithelial  type  2  cells,  or  AEC2s,  proliferation  and 
accumulation of activated myofibroblasts, deposition of extracellular matrix, or ECM, and fibrosis, resulting in labored breathing and loss of lung function. 
Damaged  AEC2s  are  unable  to  replace  injured  alveolar  epithelial  type  1  cells,  or  AEC1s,  which  make  up  the  majority  of  the  alveolar  surface  and  are 
important in mucus clearance and healthy lung function. Other than lung transplantation, no treatment has shown survival benefit. Two approved drugs, 
nintedanib  and  pirfenidone,  have  been  shown  to  reduce  the  rate  of  lung  function  decline,  but  unfortunately  provide  only  modest  clinical  benefit  in  IPF 
patients. Neither drug is curative, and significant side effects or intolerance can occur with the use of pirfenidone and nintedanib. As these approved drugs 
are focused on fibroblast proliferation, they have not demonstrated an effect on protecting or restoring healthy lung epithelial cells. We believe LTI-03 has a 
mechanism that not only reduces fibroblast proliferation but also, importantly, protects and potentially restores healthy lung epithelial cells. 

Cav1 normally serves a critical function in the prevention of fibrosis by maintaining a balance between pathways that both initiate and arrest lung 
repair and cell movement. Studies conducted by third parties have shown decreased levels of Cav1 in patients with IPF and the development of fibrosis in 
Cav1 knock-out models of fibrosis. Furthermore, we have conducted in vitro and animal model tests with LTI-03 in which we have observed a reduction in 
numerous pro-fibrotic signaling proteins. In analyzing fibrotic activity in a sample precision cut lung slice, or PCLS, tissue from an end stage IPF lung, 
LTI-03 demonstrated a broad anti-fibrotic activity similar to that of nintedanib in a single patient sample and composite of six patient samples. 

In additional PCLS testing of end stage IPF lungs with LTI-03, we observed increased viable AEC2s that are important for epithelial regeneration 

and proper lung function. We believe that this protection of AEC2s has the potential to improve IPF patients’ underlying disease. 

6

 
 
The  soluble  Receptor  of  Advanced  Glycation  End-products,  or  sRAGE,  is  a  prognostic  marker  of  IPF  disease  progression  and  is  produced  by 
AEC1s. Low levels of sRAGE at diagnosis predict poor survival in IPF and as IPF patients’ disease worsens, sRAGE declines. In further testing of PCLS 
tissue, LTI-03 administration demonstrated an increase in sRAGE versus untreated control samples. We believe the increase in sRAGE provides further 
evidence of increased AEC2 survival, possibly leading to greater AEC1 production and thus overall epithelial cell survival, and therefore the elevation of 
sRAGE levels after administration of LTI-03 in the PCLS model may indicate a beneficial impact of LTI-03 in treating IPF patients.

Phase 1a Clinical Trial 

We  completed  a  randomized,  double-blind,  placebo-controlled,  Phase  1a  clinical  trial  of  LTI-03  in  healthy  volunteers  in  the  UK.  The  primary 
objective of this trial was to determine the safety and tolerability of single and multiple ascending doses, SAD and MAD, respectively, of inhaled LTI-03. 
The secondary objective was to evaluate the pharmacokinetics of SAD and MAD daily doses for 14 days of inhaled LTI-03. 

In four SAD cohorts, 24 subjects were administered LTI-03 by inhalation at single doses of 20 mg, 40 mg, and 80 mg. At the 80 mg dose, subjects in 
one cohort were administered four 20 mg capsules by inhalation and in a second cohort, subjects were administered eight 10 mg capsules by inhalation. 
Eight  subjects  in  the  combined  SAD  cohorts  were  administered  a  placebo.  In  the  SAD  cohorts,  21  of  24  subjects  administered  LTI-03  experienced 
treatment emergent adverse events, or TEAE, the most frequent of which were mild dry coughs related to LTI-03. 

In two MAD cohorts, 12 subjects were administered LTI-03 by inhalation once daily for up to 14 days at 20 mg and 40 mg. Mild coughs, assessed 
as related to LTI-03, were the most frequent TEAEs occurring in 12 of 12 subjects over the course of the 14-day dosing period. Mild and related coughs 
occurred in three of the four subjects administered placebo. Other TEAEs occurring in more than one of the 12 subjects administered LTI-03 included sinus 
tachycardia,  which  is  a  fast  increase  in  heart  rate,  in  two  subjects  assessed  as  mild  and  not  related  in  one  and  moderate  and  related  in  the  other;  chest 
discomfort in two subjects assessed as related and moderate in one and related and severe in the other; and labored breathing in two subjects assessed as 
related and moderate in one and related and severe in the other. During dosing in the second MAD cohort of 40 mg of LTI-03, we placed the study on hold 
after one subject developed severe TEAEs and two other subjects developed moderate TEAEs secondary to pulmonary airflow limitations that appeared to 
be secondary to reversible airway obstruction. These events were considered related to LTI-03. All TEAEs were resolved within 24 hours. 

Adverse findings in the MAD 40 mg cohort, and a re-evaluation of the dose rationale based on further analysis of in vitro and in vivo data, suggest 
that lower doses should be efficacious with an improved safety profile. The 20 mg and 40 mg doses evaluated are predicted to be 21- to 39-fold in excess of 
a minimally efficacious dose. Based upon these MAD observations, three additional MAD cohorts of 2.5 mg administered once daily, 5 mg (two 2.5 mg 
capsules), and 10 mg (two 2.5 mg capsules dosed twice daily) were administered to 17 subjects for 14 days. In these lower dose cohorts, the most common 
TEAEs related to LTI-03 were mild coughs in 41% of subjects. The only other TEAEs occurring in more than one subject was mild throat irritation in two 
subjects that were assessed as related to LTI-03. The were no moderate, severe, or serious TEAEs assessed as related to LTI-03. 

Upon review of pooled plasma samples from patients in all Phase 1a cohorts up to 20 mg, there was an increase in sRAGE from day 13 treatment 

compared to pre-treatment for patients who received LTI-03 compared to patients who received placebo. 

Phase 1b Clinical Trial 

We are currently recruiting patients for a randomized, double-blind, placebo-controlled, Phase 1b clinical trial of LTI-03 in IPF patients, which is 
being conducted at 11 centers in the U.S., UK, Belgium, Germany and Australia. Patients in the trial will either receive 5 mg (one 2.5 mg capsule dosed 
twice daily) of inhaled LTI-03, 10 mg of inhaled LTI-03 (two 2.5 mg capsules dosed twice daily), or placebo in three active dose patients to one placebo 
patient randomization for 14 days in a total of 24 IPF patients. The trial will evaluate the safety, tolerability and pharmacodynamic biomarker activity of 
LTI-03. We expect to report top-line data from the Phase 1b clinical trial in the third quarter of 2024.

LTI-01 

LTI-01 is a scuPA for the treatment of LPE. Pleural effusion is defined by the build-up of fluid in the pleural cavity, predominantly resulting from 
pneumonia, and is considered loculated when fibrinous scar tissue forms, trapping the fluid and preventing drainage. LPE is an orphan disorder for which 
there  are  no  currently  approved  therapeutics.  LPEs  are  a  frequent  complication  of  pneumonia  and  develop  from  pockets  of  infected  fluid,  known  as  a 
complicated parapneumonic effusion, or CPE, or if pus is present, known as an empyema. LPEs can result in pain, shortness of breath and can rapidly lead 
to sepsis and death. CPE and empyema can be serious clinical problems which are associated with mortality of approximately 20%. Effective drainage of 
infected  pleural  effusions  is  essential  for  treatment.  We  believe  over  60,000  cases  of  LPE  associated  with  CPE  and  empyema  are  estimated  to  occur 
annually in the U.S. alone, and based upon our market research, over half of these patients are receiving off-label, intrapleural fibrinolytic therapy, or IPFT, 
which is the use of clot busting drugs injected locally into the pleural cavity to treat the LPEs. LTI-01 has been granted Orphan Drug Designation in the 
U.S. and EU for treatment of empyema and Fast Track Designation in the U.S. for the investigation of LTI-01 for the treatment of infected, non-draining 
pleural  effusion.  In  November  2020,  we  signed  a  regional  licensing  deal  with  Taiho  for  the  rights  to  develop  and  commercialize  LTI-01  in  Japan.  We
received an up-front payment of $5.0 million and may receive a future milestone payment of $10.0 million, drug supply payments and royalties on drug 
sales upon approval and commercial launch in Japan. 

Currently, there are no approved drug treatments for LPE. Given the risks of surgery and extensive days of hospitalization post-surgery, IPFT has 
been used off-label in patients with LPE to promote pleural drainage. Despite limited research of IPFT, tissue plasminogen activator, or tPA, in combination 
with recombinant deoxyribonuclease, or DNase, has become the off-label standard of care for treating LPEs in many institutions. Similar to off label IPFT, 
LTI-01  works  locally  in  the  pleural  space  by  breaking  down  the  fibrinous  scar  tissue  and  allowing  the  trapped  fluid  to  drain.  We  believe  there  are 
advantages possessed by LTI-01 over other fibrinolytics which arise from the resistance of LTI-01 to a protein which is the major inhibitor of fibrinolytic 
activity, Plasminogen Activator Inhibitor-1, or PAI-1. PAI-1 has been shown to suppress fibrinolytics like tPA by binding to them and inhibiting activity. 
LTI-01, however, has demonstrated relative resistance to PAI-1 inhibition. Animal model studies, conducted by third parties, of PAI-1 inhibition showed 
LTI-01 to be active 24 hours post administration, while tPA was shown to be inactivated in as little as 40 minutes. We believe that this provides for a longer 
duration of activity, eliminates the need for repeated daily dosing, and could confer a lower risk of bleeding. 

Based upon our Phase 2a and Phase 1b data and historical treatment data of LPE patients receiving off-label tPA with DNase in the U.S., we believe 
LTI-01 may be more beneficial to patients when compared to tPA with DNase in the treatment of LPE on dosing schedule, surgical referrals and safety 
profile.  Furthermore,  third  party  market  research  with  physician  interviews  performed  by  MME,  a  wholly-owned  subsidiary  of  Indegene,  Inc.,  suggests 
LTI-01 could potentially replace the use of tPA with DNase for LPE patients. 

Phase 2a Clinical Trial 

We completed a randomized, double-blind, placebo-controlled, Phase 2a clinical trial that was conducted at 36 centers in the U.S. to evaluate LTI-01 
in patients with infected, non-draining pleural effusions. The primary endpoint in the trial was treatment failure, defined as death or referral to surgery by 
checklist  within  seven  days  from  commencement  of  dosing.  Secondary  endpoints  included  length  of  hospital  stay,  incidence  of  bleeding  and  pain  and 
volume of pleural fluid drainage. The trial evaluated 3 doses of LTI-01, 400,000, 800,000 or 1.2 million units compared to placebo in a three to one active 
to  placebo  randomization.  Due  to  trial  delays  related  to  the  COVID-19  pandemic  and  limited  shelf  life  of  drug  product,  only  40  patients  completed 
enrollment  in  the  trial.  There  was  not  a  statistically  significant  difference  in  the  primary  endpoint  of  treatment  failure  between  treatment  arms  and  the 
placebo arm. We believe this lack of significance was due to referral to surgery checklist limitations which allowed patients, including those on placebo, to 
be  deemed  a  successful  treatment  while  also  receiving  rescue  treatment,  defined  as  either  surgery,  off  label  IPFT  or  other  intervention.  Based  upon  a 
patient’s need for a rescue treatment, either surgery, off label IPFT or other intervention, 60.0% and 55.5% of patients in the 400,000 and 800,000 dosing 
arms, respectively, did not require rescue treatment to resolve their LPE. However, 27.3% of patients in the placebo dosing group did not require a rescue 
treatment  to  resolve  their  LPE.  Moreover,  the  400,000  and  800,000  dosing  arms  showed  a  meaningful  reduction  in  volume  of  pleural  fluid  drainage,  a 
secondary endpoint. LTI-01 was well tolerated with no safety signals of concern. 

8

 
 
Based on the results of this trial, we expect to investigate LTI-01 in an additional Phase 2 dose-ranging, placebo-controlled clinical trial with a lower 

dose to establish efficacy and safety. 

Phase 1b Clinical Trial 

We completed a first-in-human, open-label, dose escalation Phase 1b safety, tolerability and proof of mechanism trial of LTI-01 in 14 LPE patients 
presenting with pneumonia and CPE or empyema. The Phase 1b clinical trial was conducted at seven clinical centers in Australia and New Zealand. LTI-01 
was administered intrapleurally once per day for up to three consecutive days at doses ranging from 50,000 units to 800,000 units. At the doses tested, LTI-
01 was well tolerated and there were no safety signals of concern. Moreover, no local or systemic bleeding was observed. All adverse events observed were 
considered unrelated to the study drug. 

LTI-01  showed  preliminary  signs  of  efficacy,  with  reductions  in  pleural  opacity  and  declines  in  pleural  infection  indicators.  Preliminary  efficacy 
findings included signs of successful treatment of the underlying infectious process with decreased C-reactive protein, or CRP, levels and total leukocyte 
and neutrophil counts, drainage of the infected pleural fluid and decreases in pleural opacity. These results suggest that LTI-01 clears scar tissue with once-
a-day dosing for three days and promotes fluid drainage around the lungs without bleeding and other side effects. 

Preclinical Programs 

We  have  multiple  programs  in  preclinical  development.  We  are  developing  LTI-05,  an  epithelial  sodium  channel,  or  ENaC,  inhibitor,  in  lead 
optimization  for  the  treatment  of  cystic  fibrosis,  or  CF,  that  has  demonstrated  sodium  channel  inhibition  and  localized  activity  in  preclinical  studies.  In 
addition, we are developing a systemic formulation of a proprietary Cav1-related peptide to be utilized for patients where a systemic delivery would be 
ideal. Cav1, from which LTI-03 is derived, has been widely studied for its role in the regulation of cell signaling and endocytosis and, we believe, restores 
balance by regulating aberrant cell signaling. Cav1 has been demonstrated to be deficient in multiple fibrotic organs in preclinical models. Independent 
preclinical research and our preclinical research have demonstrated the potential of a Cav1-related peptide to treat fibrosis in a number of organs, including 
kidney, heart and skin. This preclinical program is currently in the formulation development stage. 

Manufacturing

We do not own or operate manufacturing facilities for the production of any of our product candidates, nor do we have plans to develop our own 
manufacturing  operations  in  the  foreseeable  future.  We  currently  rely,  and  expect  to  continue  to  rely,  on  third-party  contract  manufacturers  for  the 
manufacture of all our product candidates for preclinical research and clinical trials. We do not have long-term agreements with any of these third-party 
contract manufacturers. 

If any of our product candidates are approved by any regulatory agency, we intend to enter into agreements with a third-party contract manufacturer 
and one or more back-up manufacturers for the commercial production of our product candidates. Development and commercial quantities of any drugs 
that we develop will need to be manufactured in facilities, and by processes, that comply with the requirements of the FDA and the regulatory agencies of 
other jurisdictions in which we are seeking approval. 

The  risks  associated  with  our  reliance  on  third-party  contract  manufacturers  are  described  in  Item  1A.  Risk  Factors  -  Risks  Related  to  Our 

Dependence on Third Parties in this Annual Report on Form 10-K.

Sales and Marketing 

We currently have no marketing, sales or distribution capabilities. In order to commercialize any products that are approved for commercial sale, we 
must either develop a sales and marketing infrastructure or collaborate with third parties that have sales and marketing experience. We may seek third-party 
support from established pharmaceutical and biotechnology companies for those products that would benefit from the promotional support of a large sales 
and marketing force. In these cases, we might seek to promote our products in collaboration with 

9

 
 
marketing partners or rely on relationships with one or more companies with large established sales forces and distribution systems. 

We may elect to establish our own sales force to market and sell a product for which we obtain regulatory approval if we expect that the geographic 
market for a product we develop on our own is limited or that the prescriptions for the product will be written principally by a relatively small number of 
physicians. If we decide to market and sell any products ourselves, we do not expect to establish direct sales capability until shortly before the products are 
approved for commercial sale. 

Competition

The biotechnology and biopharmaceutical industries are characterized by rapidly advancing technologies, strong competition and an emphasis on 
proprietary products. While we believe that our technology, knowledge, experience and scientific personnel provide us with competitive advantages, we 
face  substantial  competition  from  many  different  sources,  including  larger  pharmaceutical  companies  with  greater  resources.  Smaller  specialty 
biotechnology and biopharmaceutical companies, academic research institutions, governmental agencies, as well as public and private institutions are also 
potential  sources  of  competitive  products  and  technologies,  including  through  collaborative  arrangements  with  large  and  established  biopharmaceutical 
companies. We also face competition in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and enrolling 
patients  for  clinical  trials,  and  acquiring  technologies  complementary  to,  or  necessary  for,  our  programs.  We  believe  that  the  key  competitive  factors 
affecting  the  success  of  any  of  our  product  candidates  will  include  efficacy,  safety  profile,  convenience,  method  of  administration,  cost,  level  of 
promotional activity and intellectual property protection. 

There are a number of large biopharmaceutical and biotechnology companies that are currently pursuing the commercialization or development of 
products  for  the  treatment  of  fibrosis.  Companies  that  we  are  aware  of  that  are  targeting  the  treatment  of  various  fibrosis  indications  include  larger 
companies with significant financial resources such as AbbVie Inc., Boehringer Ingelheim GmbH, Bristol Myers Squibb Company, Gilead Sciences, Inc., 
Roche Holding AG, Novartis AG, and Pliant Therapeutics, Inc. However, we know of no other companies currently in clinical development with a drug 
therapeutic utilizing Cav1 and Cav1-related peptides. 

Although  our  novel  approach  is  unique  from  most  other  existing  or  investigational  therapies  across  the  disease  areas  where  we  are  focusing  our 
development,  we  will  need  to  compete  with  currently  approved  therapies,  and  potentially  those  currently  in  development  if  they  are  approved.  We  are 
aware of several marketed and investigational products in our leading disease areas, including but not limited to: 

•

•

IPF:  There  are  currently  two  approved  branded  products  for  the  treatment  of  IPF;  Esbriet,  marketed  by  Roche  Holding  AG,  and  Ofev, 
marketed  by  Boehringer  Ingelheim  GmbH.  Companies  currently  developing  product  candidates  in  IPF  include  AbbVie  Inc.,  Boehringer 
Ingelheim  GmbH,  Pliant  Therapeutics,  Inc.,  Bristol  Myers  Squibb  Company,  Avalyn  Pharma,  Inc.,  Roche  Holding  AG,  Vicore  Pharma 
Holding AB, Endeavor BioMedicines and PureTech Health plc. 

LPE: There are currently no approved drug therapies for the treatment of LPE. Roche Holding AG manufactures tPA and DNase, which is 
used  off-label  to  treat  LPE.  We  are  not  aware  of  any  other  pharmaceutical  nor  biotechnology  company  developing  drug  therapies  for  the 
treatment of LPE. 

The availability of reimbursement from government and other third-party payors will also significantly affect the pricing and competitiveness of our 
product candidates, if approved for marketing. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we 
do, which could result in our competitors establishing a strong market position before we are able to enter the market. 

Out-License Agreement 

Agreement with Taiho Pharmaceutical Co. Ltd. 

On November 12, 2020, Lung entered into a license agreement with Taiho, or the Taiho Agreement, to collaborate on the development and potential 

commercialization of LTI-01. Under the terms of the Taiho Agreement, 

10

 
 
Lung granted Taiho an exclusive, royalty-bearing license to develop, seek regulatory approval for and commercialize LTI-01 in Japan. We are obligated to 
conduct all development activities for LTI-01 through regulatory approval in the U.S. or other markets worldwide, except Japan, and retain the right to 
commercialize  LTI-01  in  all  markets  worldwide  except  Japan.  Under  the  terms  of  the  Taiho  Agreement,  we,  in  part  through  our  participation  in  a  joint

Intellectual Property 

Overview 

We strive to protect and enhance the proprietary technology, inventions and improvements that are commercially important to the development of 
our business, including seeking, maintaining and defending patent rights, whether developed internally or licensed from third parties. We also rely on trade 
secrets relating to our proprietary pipeline of product candidates and on know-how, continuing technological innovation and in-licensing opportunities to 
develop  and  strengthen  our  pipeline  that  may  be  important  for  the  development  and  growth  of  our  business.  We  additionally  may  rely  on  regulatory 
protection afforded through data exclusivity, market exclusivity and patent term extensions, where available. 

Our  commercial  success  may  depend  in  part  on  our  ability  to:  obtain  and  maintain  patent  and  other  proprietary  protection  for  commercially 
important technology, inventions and know-how related to our business; defend and enforce our patents; preserve the confidentiality of our trade secrets; 
and operate without infringing the valid enforceable patents and proprietary rights of third parties. Our ability to stop third parties from making, using, 
selling, offering to sell, or importing our products may depend on the extent to which we have rights under valid and enforceable licenses, patents, or trade 
secrets  that  cover  these  activities.  In  some  cases,  enforcement  of  these  rights  may  depend  on  third  party  licensors.  With  respect  to  both  licensed  and 
company-owned intellectual property, we cannot be sure that patents will be granted with respect to any of our pending patent applications or with respect 
to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us in the future 
will be commercially useful in protecting our commercial products and methods of manufacturing the same. 

Prior to the Lung Acquisition in October 2023, we developed our global patent property portfolio covering the composition of matter of ALRN-

6924, its methods of use, and related technology. As described above, we terminated the development of ALRN-6924 in February 2023. 

As  a  result  of  the  Lung  Acquisition,  as  of  March  5,  2024,  we  own  or  have  licensed  thirty-three  issued  patents  and  forty-one  pending  patent 
applications  worldwide,  two  pending  international  Patent  Cooperation  Treaty,  or  PCT,  patent  applications  and  one  U.S.  provisional  patent  applications, 
which  are  material  to  the  programs  described  below  relating  to  the  Lung  business.  Thirty-one  issued  patents  worldwide  and  eight  pending  patent 
applications are owned by the UT System, which have granted us exclusive license rights to the technology. We own eleven pending patent applications 
worldwide together with the UT System, which have granted us exclusive license rights to the technology. Our policy is to file patent applications to protect 
technology,  inventions  and  improvements  to  inventions  that  are  commercially  important  to  the  development  of  our  business.  We  seek  U.S.  and  foreign
patent protection for a variety of technologies, including peptides and compositions related to LTI-03 and Cav1-related peptides, methods for therapeutic 
use of peptides and conjugates of interest and diagnostic methods with peptides of interest for treating diseases of interest. We also intend to seek patent 
protection or rely upon trade secret rights to protect other technologies that may be used to discover and validate targets and identify and develop novel 
products. We seek protection, in part, through confidentiality and proprietary information agreements. We are a party to various other license agreements 
that give us rights to use specific technologies in our research and development.

As  of  March  5,  2024,  we  owned  two  pending  PCT  applications,  eight  pending  U.S.  patent  applications  including  one  pending  U.S.  provisional 
applications, and fifteen pending applications outside of the U.S. related to the LTI-03 program. We also have licensed: five U.S. patents, including U.S. 
Patent Nos. 8,697,840, 9,630,990, 10,377,796, 11,161,875, and 11,780,879, twenty-five patents granted outside of the U.S., two pending U.S. application, 
and six 

13

 
 
pending applications outside of the U.S. related to the LTI-03 program. The issued LTI-03 related patents are expected to expire in 2030 or 2034, without 
any available patent term extensions. Patents that may issue from the pending applications are expected to expire between the years 2034 and 2044, without 
any available patent term extensions. The in-licensed LTI-03 issued patents from the UT System are directed to methods of treating acute lung injury or 
pulmonary fibrosis with LTI-03 and methods of treating a condition characterized by fibrosis with LTI-03. The pending applications in the LTI-03 program 
are  directed  to  methods  for  treating  diseases  or  disorders,  including  fibrosis,  methods  for  increasing  viability  of  lung  epithelial  cells,  and  formulations, 
including dry powder formulations, as well as therapeutic uses of LTI-03 for other indications interest and diagnostic methods. 

LTI-01 Program 

As of March 5, 2024, we have a license to one U.S. patent from the UT System directed to methods of using intrapleural scuPA polypeptide for 

decreasing the severity of pleural scarring, which is expected to expire in 2024 without patent term extension. 

We expect LTI-01 to be the first to file Biologics License Application, or BLA, in the U.S., which provides for the potential of 12 years exclusivity. 
The drug is made using a complex process which would likely be difficult to duplicate. In addition, we have received Orphan Drug Designation for pleural 
empyema in both the U.S. and the EU, which designation should provide exclusivity of seven and ten years, respectively. We believe that, if the product is 
approved,  these  designations  may  afford  us  exclusivity  and  the  complex  production  of  LTI-01  will  provide  for  additional  barriers  to  entry  for  potential 
competition. 

U.S. Government Regulation of Drug and Biological Products

In the U.S., FDA regulates human drugs under the Federal Food, Drug, and Cosmetic Act (FDCA) and in the case of biologics, also under the Public 
Health  Service  Act  (PHSA)  and  their  implementing  regulations.  Failure  to  comply  with  the  applicable  U.S.  requirements  may  result  in  FDA  refusal  to 
approve  a  new  drug  application  (NDA)  or  a  Biologics  License  Application  (BLA).  Further,  non-compliance  may  delay  product  development  and  could 
subject an applicant to administrative or judicial sanctions, such as issuance of warning letters, or the imposition of fines, civil penalties, product recalls, or 
other corrective action. This could include product seizures, import alerts, total or partial suspension of production or distribution, injunctions and/or civil 
or criminal prosecution brought by FDA, with the assistance of the U.S. Department of Justice or other governmental entities.

FDA  must  approve  our  product  candidates  for  therapeutic  indications  before  they  may  be  marketed  in  the  U.S.  For  drug  products,  FDA  must 
approve an NDA, and for biologic products, FDA must approve a BLA. An applicant seeking approval to market and distribute a new drug or biologic in 
the U.S. generally must satisfactorily complete each of the following steps, where applicable:

•

•

•

•

•

•

•

completion  of  preclinical  laboratory  tests  and  animal  studies  according  to  good  laboratory  practices  (GLP)  regulations  or  other  applicable 
regulations;

manufacture  and  testing  of  the  therapeutic  or  biologic  moiety  and  its  respective  product  formulation  according  to  good  manufacturing 
practices (cGMP), regulations or other applicable regulations;

submission to FDA of an investigational new drug application (IND) which must become effective before human clinical trials may begin 
and must be updated annually and amended when certain changes are made;

approval by an independent institutional review board (IRB) or ethics committee representing each clinical trial site before each clinical trial 
may be initiated;

performance  of  adequate  and  well-controlled  human  clinical  trials  in  accordance  with  applicable  IND  regulations,  good  clinical  practices 
(GCPs)  and  other  clinical-trial  related  regulations  to  evaluate  the  safety  and  efficacy  of  the  investigational  product  for  each  proposed 
indication;

preparation  and  submission  to  FDA  of  an  NDA  or  BLA  requesting  marketing  approval  for  one  or  more  proposed  indications,  including 
payment of application user fees;

review of the NDA or BLA by an FDA advisory committee, where applicable;

14

 
 
•

•

•

satisfactory  completion  of  one  or  more  FDA  inspections  of  the  manufacturing  facility  or  facilities  at  which  the  drug  or  biologic  and  its 
respective finished product is produced to assess compliance with cGMP requirements to assure that the facilities, methods and controls are 
adequate to preserve the product’s identity, strength, quality and purity;

satisfactory  completion  of  any  FDA  audits  of  clinical  trial  sites  to  assure  compliance  with  GCPs  and  the  integrity  of  the  clinical  data 
submitted in support of the NDA or BLA; and

FDA  review  and  approval  of  the  NDA  or  BLA,  which  may  be  subject  to  additional  post-approval  requirements,  including  the  potential 
requirement to implement a Risk Evaluation and Mitigation Strategy (REMS) and any other potential post-approval studies required by FDA.

Preclinical Studies and IND

Before testing any drug or biological product candidate in humans, the product candidate must undergo rigorous preclinical testing. The preclinical 
developmental stage generally involves laboratory evaluations of drug chemistry/biology, formulation and stability, as well as in vitro and animal studies to 
assess  safety  and  in  some  cases  to  establish  a  rationale  for  therapeutic  use.  The  conduct  of  preclinical  studies  is  subject  to  federal  regulations  and 
requirements, including GLP regulations for safety and toxicology studies. The sponsor must submit the results of the preclinical studies, together with 
manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to FDA as part of the IND.

An IND is a request for authorization from FDA to administer an investigational product to humans. The IND sponsor must submit the IND and 
then wait 30 days before initiating clinical trials, so that FDA can use that time to review the submission, and raise concerns or questions related to one or 
more proposed clinical trials. Even if FDA does not raise concerns within 30 days, it could place the clinical trial on a clinical hold due to potential safety 
concerns. In such a case, the IND sponsor and FDA must resolve any outstanding concerns before the clinical trial can begin. Imposition of a clinical hold 
could cause significant delays or difficulties in initiating and/or completing planned clinical trials in a timely manner. Certain long-term preclinical testing, 
such as animal tests of reproductive adverse events and carcinogenicity, may initiate or continue after an IND for an investigational product candidate is 
submitted to FDA and human clinical trials have been initiated.

Human Clinical Trials in Support of an NDA or BLA

Clinical trials involve the administration of an investigational product candidate to healthy volunteers or patients with the disease to be treated under 
the supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives of the study, inclusion and exclusion criteria, 
dosing  procedures  and  the  parameters  to  be  used  in  monitoring  the  safety  and  effectiveness  criteria  to  be  evaluated.  Each  protocol,  as  well  as  any 
subsequent amendments, must be submitted to FDA as part of the IND.

An  IRB  representing  each  institution  that  is  participating  in  the  clinical  trial  must  review  and  approve  the  plan  for  any  clinical  trial  before  it 
commences at that institution, and the IRB must thereafter conduct a continuing review of the trial. The IRB will consider, among other things, clinical trial 
design, patient informed consent, ethical factors and the safety of human subjects. The IRB must review and approve, among other things, the trial protocol 
and  informed  consent  information  to  be  provided  to  clinical  trial  subjects  or  their  legal  representatives  and  must  operate  in  compliance  with  FDA 
regulations.

Clinical trials must also comply with extensive GCP standards intended to ensure protection of human subjects and the quality and integrity of the 
study  data,  including  requirements  for  obtaining  subjects’  informed  consent.  Additionally,  some  clinical  trials  are  overseen  by  an  independent  group  of 
qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group may recommend continuation of 
the trial as planned, changes in trial conduct or cessation of the trial at designated checkpoints based on access to certain data from the study. FDA may, at 
any  time  while  clinical  trials  are  ongoing,  impose  a  partial  or  complete  clinical  hold  based  on  concerns  for  patient  safety  and/or  noncompliance  with 
regulatory  requirements.  This  order,  if  issued  by  FDA,  would  cause  suspension  of  an  ongoing  trial  until  all  outstanding  concerns  have  been  adequately 
addressed and FDA has notified the company that investigations may proceed.

15

 
 
Human  clinical  trials  to  evaluate  therapeutic  indications  to  support  NDAs  and  BLAs  for  marketing  approval  are  typically  conducted  in  three 

sequential phases that may overlap or be combined:

•

•

•

Phase 1: The product candidate is initially introduced into human subjects and tested for safety, dosage tolerance, absorption, metabolism, 
distribution and excretion, and if possible, to gain early evidence for effectiveness. Phase 1 trials may be conducted in healthy volunteers or, 
in the case of some products for severe or life-threatening diseases, including many rare diseases, the initial human testing is often conducted 
in patients with the target disease or condition.

Phase 2: Clinical trials are conducted in a limited patient population with a specified disease or condition to identify possible adverse effects 
and  safety  risks,  to  preliminarily  evaluate  the  efficacy  of  the  product  for  specific  targeted  diseases  and  to  determine  dosage  tolerance  and 
optimal dosage. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 
clinical trials.

Phase 3: Clinical trials are undertaken with an expanded patient population to further evaluate dosage, and to provide substantial evidence of 
clinical  efficacy  and  safety  in  an  expanded  patient  population,  often  at  geographically  dispersed  clinical  study  sites.  These  studies  are 
intended to establish the overall risk- benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling. 
These trials may include comparisons with placebo and/or other comparator treatments. The duration of treatment is often extended to mimic 
the actual use of a product during marketing.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain 
additional experience from the treatment of patients in the intended therapeutic indication, or to document a clinical benefit in the case of drugs or biologics 
approved  under  FDA’s  accelerated  approval  regulations  and  generate  additional  safety  data  regarding  use  of  the  product  in  a  clinical  setting.  In  certain 
instances, FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA or BLA. Failure to exhibit due diligence with 
regard to conducting Phase 4 clinical trials could result in withdrawal of approval for the product.

FDA  or  the  sponsor  may  suspend  or  terminate  a  clinical  trial  at  any  time  on  various  grounds,  including  a  finding  that  the  research  subjects  or 
patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial if the clinical trial is not 
being conducted in accordance with the clinical protocol, GCP, or other IRB requirements or, if the drug has been associated with unexpected serious harm 
to patients.

Information about certain clinical trials, including details of the protocol and eventually study results, also must be submitted within specific time 
frames to the National Institutes of Health for public dissemination on the ClinicalTrials.gov data registry. Similar requirements for posting clinical trial 
information in clinical trial registries exist in the EU and in other countries outside the U.S.

During the development of a new drug or biological product, sponsors have the opportunity to meet with FDA at certain points, including prior to 
submission of an IND, at the end of phase 2 and before submission of an NDA or BLA. These meetings can provide an opportunity for the sponsor to share 
information about the data gathered to date and for FDA to provide advice on the next phase of development. 

Concurrent with clinical trials, companies usually complete additional nonclinical studies and must also develop additional information about the 
physical characteristics of the drug or biological product and finalize a process for manufacturing the product in commercial quantities in accordance with 
cGMP regulatory requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among 
other things, the manufacturer must develop methods for testing the identity, strength, quality, potency and purity of the final drug or biological product. 
For biological products in particular, the PHSA emphasizes the importance of manufacturing controls for products whose attributes cannot be precisely 
defined in order to help ensure safety, purity and potency.

Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate 

does not undergo unacceptable deterioration over its shelf life.

Marketing Application Submission and FDA Review

Assuming  successful  completion  of  the  required  clinical  testing,  the  results  of  the  clinical  trials  and  preclinical  studies  (along  with  information 
relating to the product’s chemistry, manufacturing, controls (CMC)) and the proposed labeling are submitted to FDA as part of an NDA or BLA, requesting 
approval to market the product for one or more indications. Data may come from company-sponsored clinical trials intended to test the safety and efficacy 
of a product’s use or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, FDA must find the 
data  submitted  to  be  sufficient  to  establish  the  safety  and  efficacy  of  the  investigational  product  for  its  proposed  indication.  The  fee  required  for  the 
submission of an NDA or BLA under the Prescription Drug User Fee Act (PDUFA), is substantial (for example, for fiscal year 2024 this application fee is 
approximately $4 million), and the sponsor of an approved NDA or BLA is also subject to an annual program fee, which is currently more than $400,000
per  program.  These  fees  are  adjusted  annually,  but  exemptions  and  waivers  may  be  available  under  certain  circumstances.  No  user  fee  is  required  for 
orphan drug product applications, except when an application also includes an indication for a non-rare disease or condition.

FDA conducts a validation of all NDAs and BLAs within 60 days of receipt and informs the sponsor by the 74th day after FDA’s receipt of the 
submission  whether  an  application  is  sufficiently  complete  to  permit  substantive  review.  FDA  may  request  additional  information  rather  than  accept  an 
NDA or BLA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to 
review before FDA accepts it for filing.

After the submission is accepted for filing, FDA begins an in-depth substantive review of the application. Under the goals and policies agreed to by 
FDA under PDUFA, FDA has ten months from the filing date (following the 60-day validation period) in which to complete its initial review of a standard 
application and respond to the applicant and six months from the filing date for an application with “Priority Review.” The review process may be extended 
by  FDA  for  three  additional  months  to  consider  new  information  or  in  the  case  of  a  clarification  provided  by  the  applicant  to  address  an  outstanding 
deficiency identified by FDA following the original submission. Despite these review goals, it is not uncommon for FDA review of an NDA or BLA to 
extend beyond the PDUFA goal date.

Before approving an NDA or BLA, FDA will typically conduct a pre-approval inspection of the manufacturing facilities for the therapeutic/biologic 
to  determine  whether  the  manufacturing  processes  and  facilities  comply  with  GMPs.  FDA  will  not  approve  the  product  unless  it  determines  that  the 
manufacturing processes and facilities comply with cGMP regulatory requirements and are adequate to ensure consistent production of the product within 
required  specifications.  FDA  also  may  inspect  the  sponsor  and  one  or  more  clinical  trial  sites  to  ensure  compliance  with  GCP  requirements  and  the 
integrity of the clinical data submitted to FDA.

Additionally, FDA may refer any NDA or BLA, including applications for novel product candidates which present difficult questions of safety or 
efficacy, to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. 
Typically,  an  advisory  committee  is  a  panel  of  independent  experts,  including  clinicians  and  other  scientific  experts.  FDA  is  not  bound  by  the 
recommendation  of  an  advisory  committee,  but  it  considers  such  recommendations  when  making  final  decisions  on  approval.  FDA  also  may  require 
submission of a REMS, if it determines that a REMS is necessary to ensure that the benefits of the drug outweigh its risks and to assure the safe use of the 
drug  or  biological  product.  If  FDA  concludes  a  REMS  is  needed,  the  sponsor  of  the  NDA  or  BLA  must  submit  a  proposed  REMS  and  FDA  will  not 
approve the NDA or BLA without a REMS.

Under the Pediatric Research Equity Act of 2003 (PREA), an NDA or a BLA or certain supplements thereto must contain data that are adequate to 
assess  the  safety  and  effectiveness  of  the  product  for  the  claimed  indications  in  all  relevant  pediatric  subpopulations,  and  to  support  dosing  and 
administration  for  each  pediatric  subpopulation  for  which  the  product  is  safe  and  effective,  unless  this  requirement  is  waived,  deferred  or  inapplicable. 
Sponsors must submit a pediatric study plan to FDA outlining the proposed pediatric study or studies they plan to conduct, including study objectives and 
design, any deferral or waiver requests, and other information required by regulation. FDA must then review the information submitted, consult with the 
sponsor, and agree upon a final plan. FDA or the applicant may request an amendment to the plan at any time. In general, PREA requirements do not apply 
to drugs or biologics for indications granted Orphan Drug Designation by FDA.

17

 
 
FDA  reviews  an  NDA  or  a  BLA  to  determine,  among  other  things,  whether  a  product  is  safe  and  effective  for  its  intended  use,  and  whether  its 
manufacturing  is  cGMP-compliant  to  ensure  and  preserve  the  product’s  identity,  strength,  quality  and  purity.  The  approval  process  is  lengthy  and  often 
difficult, and FDA may refuse to approve an NDA or a BLA if the applicable regulatory criteria are not satisfied, or may require additional clinical or other 
data  and  information.  After  evaluating  the  application  and  all  related  information  (including  the  advisory  committee  recommendations,  if  any)  and 
inspection reports of manufacturing facilities and clinical trial sites, FDA may issue either an approval letter or a Complete Response Letter (CRL). It could 
also  issue  a  Refuse  to  File  letter  that,  in  its  current  state,  the  NDA  or  BLA  is  insufficient  to  initiate  an  FDA  review.  An  approval  letter  authorizes 
commercial marketing of the product with specific prescribing information for specific indications. A CRL indicates that the review cycle of the application 
is complete, and the application will not be approved in its present form. A CRL generally outlines the deficiencies in the submission and may require 
substantial  additional  testing  or  information  in  order  for  FDA  to  reconsider  the  application.  The  CRL  may  require  additional  clinical  or  other  data, 
additional  pivotal  Phase  3  clinical  trial(s)  and/or  other  significant  and  time-consuming  requirements  related  to  clinical  trials,  preclinical  studies  or 
manufacturing. If a CRL is issued, the applicant may either resubmit the NDA or BLA addressing all of the deficiencies identified in the letter, or withdraw 
the  application.  If  and  when  those  deficiencies  have  been  addressed  to  FDA’s  satisfaction  in  a  resubmission  of  the  NDA  or  BLA,  FDA  will  issue  an 
approval letter. FDA has committed to reviewing such resubmissions in response to an issued CRL in either two or six months depending on the type of 
information included. Even with the submission of this additional information, however, FDA ultimately may decide that the application does not satisfy 
the regulatory criteria for approval.

If a product receives regulatory approval from FDA, the approval is limited to the conditions of use (e.g., patient population, indication) described in 
FDA-approved labeling. Further, depending on the specific risk(s) to be addressed, FDA may require that contraindications, warnings, or precautions be 
included  in  the  product  labeling  (including  specific  safety-related  label  warnings).  FDA  may  also  require  that  post-approval  trials,  including  Phase  4 
clinical  trials,  be  conducted  to  further  assess  a  product’s  safety  after  approval,  require  testing  and  surveillance  programs  to  monitor  the  product  after 
commercialization or impose other conditions, including distribution and use restrictions, or other risk management mechanisms under a REMS, which can 
materially affect the potential market and profitability of the product. FDA may prevent or limit further marketing of a product based on the results of post-
marketing trials or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing 
changes and additional labeling claims, are subject to further testing requirements, and FDA review and approval.

Expedited Programs for Serious Conditions

FDA is authorized to designate certain products for expedited development or review if they are intended to address an unmet medical need in the 
treatment of a serious or life-threatening disease or condition. These programs include Fast Track Designation, Breakthrough Therapy Designation, Priority 
Review Designation and accelerated approval.

To be eligible for a Fast Track Designation, FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or 
life-threatening disease or condition and demonstrates the potential to address an unmet medical need by providing a therapy where none exists or a therapy 
that may be potentially superior to existing therapy based on efficacy or safety factors. Fast Track Designation provides opportunities for more frequent 
interactions with FDA review team to expedite development and review of the product. FDA also may review sections of the NDA or BLA for a fast track 
product on a rolling basis before the complete application is submitted if the sponsor and FDA agree on a schedule for the submission of the application 
sections and the sponsor pays any required user fees upon submission of the first section of the NDA or BLA. Fast Track Designation may be rescinded by 
FDA if the designation is no longer supported by data emerging from the clinical trial process. Fast Track Designation does not guarantee product approval.

In addition, a new drug or biological product may be eligible for Breakthrough Therapy Designation if it is intended, alone or in combination with 
one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the drug or 
biologic may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment 
effects  observed  early  in  clinical  development.  Breakthrough  Therapy  Designation  provides  all  the  features  of  Fast  Track  Designation  in  addition  to 
intensive guidance on an efficient development program beginning as early as Phase 

18

 
 
1,  and  FDA  organizational  commitment  to  expedited  development,  including  involvement  of  senior  managers  and  experienced  review  staff  in  a  cross-
disciplinary  review,  where  appropriate.  Breakthrough  Therapy  Designation  may  be  rescinded  by  FDA  if  the  designation  is  no  longer  supported. 
Breakthrough Therapy Designation does not guarantee product approval.

FDA  may  designate  a  product  for  Priority  Review  if  it  is  a  drug  or  biologic  that  treats  a  serious  condition  and,  if  approved,  would  provide  a 
significant  improvement  in  safety  or  effectiveness.  FDA  determines  at  the  time  that  the  marketing  application  is  submitted,  on  a  case-by-case  basis, 
whether the proposed drug or biologic qualifies for Priority Review. Significant improvement over available therapies may be illustrated, for example, by 
evidence of increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting drug reaction, documented 
enhancement of patient compliance that may lead to improvement in serious outcomes, or evidence of safety and effectiveness in a new subpopulation. A 
Priority Review Designation is intended to direct overall attention and resources to the evaluation of such applications and to shorten FDA’s goal for taking
action on a marketing application from ten months to six months for an original BLA or NDA from the date of filing.

Fast Track Designation, Breakthrough Therapy Designation and Priority Review do not change the standards for approval and may not ultimately 

expedite the development or approval process.

Finally, FDA may grant accelerated approval to a product for a serious or life-threatening condition that provides meaningful therapeutic advantage 
to patients over existing treatments based upon a determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict 
clinical benefit. FDA may also grant accelerated approval for such a condition when the product has an effect on an intermediate clinical endpoint that can 
be measured earlier than an effect on irreversible morbidity or mortality (IMM), and that is reasonably likely to predict an effect on IMM or other clinical 
benefit,  taking  into  account  the  severity,  rarity,  or  prevalence  of  the  condition  and  the  availability  or  lack  of  alternative  treatments.  For  drugs  granted
accelerated  approval,  FDA  generally  requires  sponsors  to  conduct,  in  a  diligent  manner,  additional  post-approval  confirmatory  studies  to  verify  and 
describe the product’s clinical benefit. Failure to conduct required post-approval studies with due diligence, failure to confirm a clinical benefit during the 
post-approval studies, or dissemination of false or misleading promotional materials would allow FDA to withdraw the product approval on an expedited 
basis. All promotional materials for product candidates approved under accelerated approval are subject to prior review by FDA unless FDA informs the 
applicant otherwise.

Post Approval Requirements

Following  approval  of  a  new  product,  the  manufacturer  and  the  approved  product  are  subject  to  pervasive  and  continuing  regulation  by  FDA, 
governing, among other things, manufacturing and quality-related compliance, monitoring and recordkeeping activities, reporting of adverse experiences 
with the product and product problems to FDA, product sampling and distribution, manufacturing and promotion and advertising. Although physicians may 
prescribe legally available products for unapproved uses or patient populations, known as off-label uses, manufacturers may not market or promote such 
uses. FDA and other agencies, including state regulatory bodies, actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a 
company that is found to have improperly promoted off-label uses may be subject to significant liability.

If there are any modifications to the product, including changes in indications, labeling, or manufacturing processes or facilities, the applicant may 
be required to submit and obtain FDA approval of a new NDA/BLA or an NDA/BLA supplement, which may require the applicant to develop additional 
data or conduct additional clinical trials and preclinical studies. FDA may also place other conditions on approvals including the requirement for a REMS 
to assure the safe use of the product, which may require substantial commitment of resources post-approval to ensure compliance. A REMS could include 
medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries, and other risk 
minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of 
products. Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing.

FDA  regulations  require  that  drug  and  biological  products  be  manufactured  in  specific  approved  facilities  and  in  accordance  with  cGMPs.  The 
cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product 
containers and closures, production and 

19

 
 
process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports and returned or salvaged products. The 
manufacturing facilities for our product candidates must meet cGMP regulatory requirements and satisfy FDA or comparable foreign regulatory authorities 
before any product is approved and our commercial products can be manufactured. In addition, for any of our product candidates that include a device 
delivery system, the device component will be subject to aspects of the Quality System Regulations (QSRs) applicable to medical devices. 

We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with 
cGMP  regulations.  These  manufacturers  must  comply  with  cGMP  regulations,  including  requirements  for  quality  control  and  quality  assurance,  the 
maintenance  of  records  and  documentation  and  the  obligation  to  investigate  and  correct  any  deviations  from  cGMP.  Manufacturers  and  other  entities 
involved  in  the  manufacture  and  distribution  of  approved  drugs  or  biologics  are  required  to  register  their  establishments  with  FDA  and  certain  state 
agencies and are subject to periodic unannounced inspections by FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, 
manufacturers  must  continue  to  expend  time,  money  and  effort  in  the  area  of  production  and  quality  control  to  maintain  cGMP  compliance.  Future 
inspections by FDA and other regulatory agencies may identify compliance issues at the facilities of our Contract Manufacturing Organizations that may 
disrupt  production  or  distribution,  or  require  substantial  resources  to  correct.  In  addition,  the  discovery  of  conditions  that  violate  these  rules,  including 
failure to conform to cGMPs, could result in enforcement actions, and the discovery of problems with a product after approval may result in restrictions on 
a product, manufacturer, or holder of an approved NDA or BLA, including voluntary recall and regulatory sanctions as described below.

Once an approval of a drug/biologic product is granted, FDA may withdraw the approval if compliance with regulatory requirements and standards 
is not maintained, or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including 
adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in 
mandatory revisions to the approved labeling to add new safety information, imposition of post-market clinical trials requirement to assess new safety risks, 
or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

•

•

•

•

•

•

•

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market, or product recalls;

safety alerts, Dear Healthcare Provider letters, press releases, or other communications containing warnings or other safety information about 
a product;

mandated modification of promotional materials and labeling, and issuance of corrective information;

fines, warning letters, untitled letters, or other enforcement-related letters or clinical holds on post- approval clinical trials;

refusal of FDA to approve pending NDAs/BLAs or supplements to approved NDAs/BLAs, or suspension or revocation of product approvals;

product seizure or detention, or refusal to permit the import or export of products;

injunctions or the imposition of civil or criminal penalties; and

consent  decrees,  corporate  integrity  agreements,  debarment,  or  exclusion  from  federal  health  care  programs;  or  mandated  modification  of 
promotional materials and labeling and the issuance of corrective information.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act (PDMA), which regulates the 
distribution of drugs and drug samples at the federal level and sets minimum standards for the registration and regulation of drug distributors by the states. 
Additionally, the Drug Supply Chain Security Act (DSCSA) imposes requirements related to identifying and tracing certain prescription drugs distributed 
in the U.S., including most biological products.

U.S. Patent Term Restoration and Hatch-Waxman Marketing Exclusivity

20

 
 
Depending upon the timing, duration and specifics of FDA approval for our product candidates, some of our U.S. patents may be eligible for limited 
patent  term  extension  under  the  Drug  Price  Competition  and  Patent  Term  Restoration  Act  of  1984,  commonly  referred  to  as  the  Hatch-Waxman 
Amendments. The Hatch-Waxman Amendments permit restoration of the patent term up to five years as compensation for patent term lost during FDA 
regulatory review process. Patent-term restoration, however, cannot extend the remaining term of a patent beyond a total of 14 years from the product’s 
approval date, and only those claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. The 
patent-term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or a BLA, plus the 
time  during  which  the  applicant  failed  to  exercise  due  diligence.  Only  one  patent  applicable  to  an  approved  drug  is  eligible  for  the  extension,  and  the 
application  for  the  extension  must  be  submitted  prior  to  the  expiration  of  the  patent.  The  U.S.  Patent  and  Trademark  Office,  in  consultation  with  FDA,
reviews and approves the application for any patent term extension or restoration. Regulatory exclusivity provisions under the FDCA also can delay the 
submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the U.S. to the first 
applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if FDA has not previously approved any other new drug 
containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, FDA may 
not accept for review an abbreviated new drug application, or a 505(b)(2) NDA submitted by another company for another version of such drug. However, 
an application may be submitted after four years if it contains a certification of patent invalidity, non-infringement, or unenforceability for the listed drug. 
An applicant may also submit a full 505(b)(1) NDA.

The FDCA also provides three years of exclusivity for a full NDA, 505(b)(2) NDA, or supplement to an existing NDA if new clinical investigations, 
other than bioavailability studies, conducted or sponsored by the applicant are deemed by FDA to be essential to the approval of the application. This three-
year exclusivity covers only the conditions of use associated with the new clinical investigations and does not prohibit FDA from approving competitor 
products for drugs that fall outside the scope of the exclusivity. Three-year exclusivity will not delay the submission or approval of a full NDA; it delays 
approval  of  a  505(b)(2)  NDA  or  an  abbreviated  new  drug  applications.  or  ANDA,  covered  by  the  exclusivity,  until  the  exclusivity  expires,  but  not  the 
submission itself.

In  addition,  both  drugs  and  biologics  can  obtain  pediatric  exclusivity  in  the  U.S.  pediatric  exclusivity,  if  granted,  adds  six  months  to  existing 
exclusivity  periods  and  patent  terms  (it  is  not  a  patent  term  extension  itself).  This  six-month  exclusivity,  which  runs  from  the  end  of  other  exclusivity 
protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for 
such a study.

Biosimilars and Reference Product Exclusivity for Biological Products

In  March  2010,  the  Patient  Protection  and  Affordable  Care  Act  was  enacted  in  the  U.S.  and  included  the  Biologics  Price  Competition  and 
Innovation Act of 2009 (BPCIA). The BPCIA amended the PHSA to create an abbreviated approval pathway for biological products that are biosimilar to 
or interchangeable with an FDA-licensed reference biological product. To date, FDA has approved a number of biosimilars. FDA has also issued several 
guidance documents outlining its approach to reviewing and approving biosimilars and interchangeable biosimilars.

Under  the  BPCIA,  a  manufacturer  may  submit  an  application  that  is  “biosimilar  to”  or  “interchangeable  with”  a  previously  approved  biological 
product or “reference product.” In order for FDA to approve a biosimilar product, it must find that there are no clinically meaningful differences between 
the reference product and proposed biosimilar product in terms of safety, purity and potency. For FDA to approve a biosimilar product as interchangeable 
with a reference product, the agency must find that the biosimilar product can be expected to produce the same clinical results as the reference product and 
(for products administered multiple times) that the biologic and the reference biologic may be switched after one has been previously administered without 
increasing  safety  risks  or  risks  of  diminished  efficacy  relative  to  exclusive  use  of  the  reference  biologic.  Upon  licensure  by  FDA,  an  interchangeable 
biosimilar may be substituted for the reference product without the intervention of the health care provider who prescribed the reference product, although 
to date no such products have been approved for marketing in the U.S.

The biosimilar applicant must demonstrate that the product is biosimilar based on data from analytical studies showing that the biosimilar product is 
highly  similar  to  the  reference  product,  data  from  animal  studies  (including  toxicity)  and  data  from  one  or  more  clinical  studies  to  demonstrate  safety, 
purity and potency in one or more appropriate conditions of use for which the reference product is approved. In addition, the applicant must show that 

21

 
 
the  biosimilar  and  reference  products  have  the  same  mechanism  of  action  for  the  conditions  of  use  on  the  label,  route  of  administration,  dosage  and 
strength, and the production facility must meet standards designed to assure product safety, purity, and potency.

A  reference  biological  product  is  granted  12  years  of  data  exclusivity  from  the  time  of  first  licensure  of  the  product,  and  the  first  approved 
interchangeable biologic product will be granted an exclusivity period of up to one year after it is first commercially marketed. FDA will not accept an 
application  for  a  biosimilar  or  interchangeable  product  based  on  the  reference  biological  product  until  four  years  after  the  date  of  first  licensure  of  the 
reference product.

The BPCIA is complex and only beginning to be interpreted and implemented by FDA. In addition, recent government proposals have sought to 
reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have 
also been the subject of recent litigation. As a result, the ultimate impact, implementation and meaning of the BPCIA is subject to significant uncertainty.

Orphan Drug Designation and Exclusivity

Orphan  Drug  Designation  in  the  U.S.  is  designed  to  encourage  sponsors  to  develop  products  intended  for  the  treatment  of  rare  diseases  or 
conditions. In the U.S., a rare disease or condition is statutorily defined as a condition that affects fewer than 200,000 individuals in the U.S. or that affects 
more than 200,000 individuals in the U.S. and for which there is no reasonable expectation that the cost of developing and making the product available for 
the disease or condition will be recovered from sales of the product in the U.S.

Orphan Drug Designation qualifies a company for certain tax credits. Designation does not guarantee approval. In addition, if a product candidate 
that has Orphan Drug Designation subsequently receives the first FDA approval for that drug for the disease for which it has such designation, the product 
may  receive  seven-year  orphan  drug  exclusivity,  which  means  that  FDA  may  not  approve  any  other  applications  to  market  the  same  drug  for  the  same 
indication for seven years following product approval unless the subsequent product candidate is demonstrated to be clinically superior. Absent a showing 
of clinical superiority, FDA cannot approve the same product made by another manufacturer for the same indication during the market exclusivity period 
unless it has the consent of the sponsor, or the sponsor is unable to provide sufficient quantities.

A sponsor may request Orphan Drug Designation of a previously unapproved product or new orphan indication for an already marketed product. 
More  than  one  sponsor  may  receive  Orphan  Drug  Designation  for  the  same  product  for  the  same  rare  disease  or  condition,  but  each  sponsor  seeking 
Orphan  Drug  Designation  must  file  a  complete  orphan  disease  designation  application.  To  qualify  for  orphan  exclusivity,  however,  the  drug  must  be 
clinically superior to the previously approved product that is the same drug for the same condition. If a product designated as an orphan drug ultimately 
receives marketing approval for an indication broader than what was designated in its orphan drug application, it may not be entitled to exclusivity.

LTI-01 has been granted Orphan Drug Designation by FDA and European Medicines Agency (EMA) for the treatment of pleural empyema. LTI-03 

has been granted Orphan Drug Designation by FDA for treatment of IPF.

Regulation Outside of the U.S.

In  addition  to  regulations  in  the  U.S.,  we  will  be  subject  to  a  variety  of  foreign  regulations  governing  clinical  trials  and  commercial  sales  and 
distribution  of  our  products  outside  of  the  U.S.  Whether  or  not  we  obtain  FDA  approval  for  a  product  candidate,  we  must  obtain  approval  by  the 
comparable regulatory authorities of foreign countries or economic areas, such as the 27-member EU, before we may commence clinical trials or market 
products in those countries or areas.

The United Kingdom is no longer part of the European Single Market and European Union Customs Union.  Though a significant proportion of the 
regulatory framework for pharmaceutical products in the United Kingdom covering the quality, safety, and efficacy of pharmaceutical products, clinical 
trials, marketing authorization, commercial sales, and distribution of pharmaceutical products is derived from EU Directives and Regulations, there 

22

 
 
are some significant changes made to the regulatory framework to address the United Kingdom's departure from the EU.  

The  Medicines  and  Healthcare  products  Regulatory  Agency,  or  the  MHRA,  is  the  national  regulator  responsible  for  supervising  medicines  and 
medical  devices  in  the  United  Kingdom,  comprising  England,  Scotland,  Wales  and  Northern  Ireland.    England,  Scotland  and  Wales  form  Great  Britain 
which follows domestic law, whereas Northern Ireland currently continues to be subject to European Union rules under the Northern Ireland Protocol. The 
main domestic legislation regulating medicines in the UK is the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), or the HMR. The HMR 
has incorporated into domestic law some of the body of European Union law instruments governing medicinal products that pre-existed prior to the United 
Kingdom’s  withdrawal  from  the  European  Union  and  has  been  amended  to  take  into  account  the  country's  departure  from  the  EU.  Other  domestic  law
implements the other corpus of EU medicines law that existed prior to the UK's departure from the EU.

Following  Brexit,  national  marketing  authorizations  in  the  UK  can  be  obtained  to  cover  the  whole  of  the  UK  (UKMA(UK)),  Great  Britain 
(UKMA(GB))  or  Northern  Ireland  (UKMA(NI)),  through  the  different  available  marketing  authorization  routes.  Northern  Ireland  also  continues  to 
participate in the EU marketing authorization routes.  In this case, the UK for the purpose of Northern Ireland can be a concerned member state (not a 
reference member state) for medicines going through the decentralized or mutual recognition procedure. Northern Ireland can also be included within the 
scope of the centralized procedure. 

Any  marketing  authorizations  granted  by  the  MHRA  under  the  decentralized  or  mutual  recognition  procedure  before  Brexit  became  national 
marketing authorizations covering the whole of the UK.  Centrally authorized products were converted to a UKMA(GB) on January 1, 2021 unless the 
marketing authorization holder informed the MHRA otherwise, and centrally authorized products continued to be recognized in Northern Ireland.

Until  December  31,  2023,  the  European  Commission  Decision  Reliance  Procedure  (ECDRP)  could  be  used  to  obtain  a  UKMA(GB)  with  the 
MHRA relying on a decision taken by the European Commission on the approval of a new MA under the centralized procedure. Similarly, the MHRA 
could grant UKMA(UK) or UKMA(GB) marketing authorizations under the decentralized and mutual recognition reliance procedure (MRDCRP). 

From January 1, 2024, the ECDRP is replaced by a new International Recognition Procedure (IRP). The MRDCRP will be incorporated within the 
IRP.  ECDRP  and  MRDCRP  submissions  received  by  the  MHRA  before  January  1,  2024  continue  to  follow  existing  procedures,  but  for  ECDRP 
applications the CHMP positive opinion (but not necessarily the European Commission Decision) should have been received before December 31, 2023. 
The IRP procedure is open to applicants who have received an authorization for the same product in one of the MHRA's specified Reference Regulators.  
The current Reference Regulators include (among others) the FDA, EMA and the national competent authorities of EU / EEA countries. 

The start dates of the data and market exclusivity periods for medicines in the UK will depend on which route it was granted.  In respect to orphan 
drugs, the general position under the HMR is 10 years' orphan market exclusivity awarded from the date of authorization by the MHRA (which can be 
reduced to six years at the end of the fifth year if the licensing authority is satisfied that the orphan criteria is no longer met).  An additional two years may 
be  granted  where  pediatric  data  requirements  are  met.  A  UK-wide  orphan  marketing  authorization  can  only  be  granted  in  the  absence  of  an  active  EU 
designation. 

On  February  27,  2023,  the  UK  and  the  EU  agreed  the  Windsor  Framework  which  addresses  (among  other  things)  the  supply  of  medicines  into 
Northern Ireland.  It provides that medicines must be approved and licensed on a UK-wide basis by the MHRA with the same labelling and packaging 
across the whole of the UK. The EMA will have no role in the approval of new medicines for Northern Ireland.  The arrangement takes effect from January 
1, 2025. 

Since  a  significant  proportion  of  the  regulatory  framework  for  pharmaceutical  products  in  the  United  Kingdom  covering  the  quality,  safety,  and 
efficacy of pharmaceutical products, clinical trials, marketing authorization, commercial sales, and distribution of pharmaceutical products is derived from 
EU Directives and Regulations, with some amendments made to address the United Kingdom's departure from the EU, Brexit may have a material impact 
upon the regulatory regime with respect to the development, manufacture, importation, approval and 

23

 
 
commercialization of product candidates in the United Kingdom. However, there are new routes to obtaining marketing authorizations available such as the 
IRP.

With the exception of the EU or European Economic Area, or EEA, applying the harmonized regulatory rules for medicinal products, the approval 
process  and  requirements  governing  the  conduct  of  clinical  trials,  product  licensing,  pricing  and  reimbursement  vary  greatly  between  countries  and 
jurisdictions and can involve additional testing and additional administrative review periods. The time required to obtain approval in other countries and 
jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure 
regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory 
process in others.

European Union Drug Development, Review and Approval

In the EU, our product candidates are subject to extensive regulatory requirements. As in the U.S., medicinal products can be marketed only if a 
marketing  authorization  from  the  competent  regulatory  agencies  has  been  obtained.  Similar  to  the  U.S.,  the  various  phases  of  preclinical  and  clinical 
research in the EU are subject to significant regulatory controls.

The Clinical Trials Regulation (EU) No 536/2014, which came into application on January 31, 2022, governs the system for the approval of clinical 

trials in the EU. 

The extent to which clinical trials, which were ongoing on January 31, 2022 are governed by the Clinical Trials Regulation depends on the date 
when  the  request  for  authorization  of  a  clinical  trial  has  been  submitted  and  on  the  duration  of  the  individual  clinical  trial.  Generally,  according  to  the 
transitional provisions, if the request for authorization of a clinical trial has been submitted before the date of application of the Clinical Trials Regulation 
(i.e.  before  January  31,  2022)  and  the  clinical  trial  continues  for  more  than  three  years  from  the  day  on  which  the  Clinical  Trials  Regulation  becomes 
applicable  (i.e.  beyond  January  31,  2025),  the  Clinical  Trials  Regulation  will  at  that  time  begin  to  apply  to  the  clinical  trial.  Until  then  the  predecessor 
provisions of the Clinical Trials Directive 2001/20/EC, Directive 2005/28/EC on GCP and the related national implementing provisions of the individual 
EU Member States apply. 

The Clinical Trials Regulation aims to simplify and streamline the approval of clinical trials in the EU. The main characteristics of the regulation 
include:  a  streamlined  application  procedure  via  a  single  entry  point,  the  “EU  portal”;  a  single  set  of  documents  to  be  prepared  and  submitted  for  the 
application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the assessment of applications for clinical 
trials, which is divided in two parts. Part I is assessed by the competent authorities of all EU Member States in which an application for authorization of a 
clinical trial has been submitted (Member States concerned). Part II is assessed separately by each Member State concerned. Strict deadlines have been 
established for the assessment of clinical trial applications. The role of the relevant ethics committees in the assessment procedure continues to be governed 
by the national law of the concerned EU Member State. However, overall related timelines have been defined by the Clinical Trials Regulation.

If any of our product candidates that, if used separately, would be considered a medicinal product is incorporated, as an integral part, in a medical 
device intended to administer the medicinal product, and the action of the medicinal product is principal and not ancillary to that of the device, then the 
combination  product  is  regulated  by  Directive  2001/83/EC  or  Regulation  (EC)  726/2004  as  a  medicinal  product.  However,  the  medical  device  used  for 
administration must satisfy the requirements for its general safety and performance under EU law governing general medical devices.

The EU regulatory regime under Directive 93/42/EEC, or the Medical Devices Directive, was replaced by Regulation (EU) 2017/745 on medical 
devices, or the Medical Devices Regulation as of May 26, 2021, subject to the transitional provisions for medical devices to remain on the EU market for a 
limited period if they were certified or, if certification was not required, a EU declaration of conformity had been drawn up under the Medical Devices 
Directive. There are significant changes to the EU regulatory system governing medical devices under the Medical Devices Regulation.

24

 
 
Under the Medical Devices Regulation, data resulting from the conformity assessment relating to the general safety and performance of the medical 
device  that  is  part  of  a  combination  product  regulated  by  Directive  2001/83/EC  or  Regulation  (EC)  726/2004  shall  be  included  in  the  application  for 
marketing authorization for the combination product. Such information must be provided by the manufacturer of the medical device in its EU declaration of 
conformity, or the relevant certificate issued by a notified body allowing the medical device manufacturer to affix a European Conformity, or CE mark to 
the medical device. If the dossier submitted to support the marketing authorization for a combination product within the scope of Directive 2001/83/EC or 
Regulation  (EC)  726/2004  does  not  include  the  results  of  the  conformity  assessment  and  where  for  the  conformity  assessment  of  the  device,  if  used 
separately, the involvement of a notified body is required in accordance with the Medical Devices Regulation, the medicinal products authority such as the 
EMA can require the applicant for a marketing authorization to provide an opinion on the conformity of the device part with the relevant general safety and 
performance requirements issued by a designated notified body.

For  marketing  authorization  applications,  or  MAA,  the  law  provides  for  the  so-called  centralized  authorization  and  authorization  procedures  in
individual EU member states, whereas the Mutual Recognition or Decentralized procedure is mandatory for a product to be authorized in more than one EU 
member state.

Centralized Procedure

The centralized procedure provides for the grant of a single marketing authorization following a favorable opinion by the EMA that is valid in all 
EU  Member  States,  as  well  as  Iceland,  Liechtenstein  and  Norway,  which  are  part  of  the  EEA.  The  centralized  procedure  is  compulsory  for  medicines 
produced by specified biotechnological processes, products designated as orphan medicinal products, advanced-therapy medicines (such as gene-therapy, 
somatic cell- therapy or tissue-engineered medicines) and products with a new active substance indicated for the treatment of specified diseases, such as 
HIV/  AIDS,  cancer,  diabetes,  neurodegenerative  disorders  or  autoimmune  diseases  and  other  immune  dysfunctions  and  viral  diseases.  The  centralized
procedure is optional for products that represent a significant therapeutic, scientific or technical innovation, or whose authorization would be in the interest 
of public health. Under the centralized procedure the maximum timeframe for the evaluation of an MAA by the EMA is 210 days, excluding clock stops, 
when additional written or oral information is to be provided by the applicant in response to questions asked by the Committee for Medicinal Products for 
Human Use, or the CHMP. Accelerated assessment might be granted by the CHMP in exceptional cases, when a medicinal product is expected to be of a
major  public  health  interest,  particularly  from  the  point  of  view  of  therapeutic  innovation.  The  timeframe  for  the  evaluation  of  an  MAA  under  the 
accelerated assessment procedure is of 150 days, excluding stop-clocks.

National Authorization Procedures

There are also two other possible routes to authorize medicinal products in several EU countries, which are available for medicinal products that fall 

outside the scope of the centralized procedure:

•

•

Decentralized  procedure.  Using  the  decentralized  procedure,  an  applicant  may  apply  for  simultaneous  authorization  in  more  than  one  EU 
country of medicinal products that have not yet been authorized in any EU country and that do not fall within the mandatory scope of the 
centralized  procedure.  The  applicant  may  choose  a  member  state  as  the  reference  member  State  to  lead  the  scientific  evaluation  of  the 
application.

Mutual recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one EU Member State (which acts as the 
reference member state), in accordance with the national procedures of that country. Following this, further marketing authorizations can be
progressively sought from other EU countries in a procedure whereby the countries concerned agree to recognize the validity of the original, 
national marketing authorization produced by the reference member state.

Under the above-described procedures, before granting the marketing authorization, the competent authorities of the EU Member States have 90 
days  to  review  the  assessment  report  rendered  by  the  reference  member  state.  Approval  of  the  assessment  report  may  be  only  denied  for  the  reason  of 
potential  serious  risk  for  public  health.  In  case  of  diverging  views  among  the  member  states,  a  coordination  procedure  at  EU  level  applies,  leading 
ultimately to a uniform decision binding on the member states.

25

 
 
On April 26, 2023, the European Commission presented a draft for a comprehensive reform of the pharmaceutical legislation. The so-called “EU 
pharmaceutical package” does not intend to change the existing procedures currently in place at EU level: Medicinal products are still to be approved in the 
decentralized  procedure,  mutual  recognition  procedure,  or  centralized  procedure.  However,  the  duration  of  authorization  procedures  is  generally  to  be 
reduced. The decisive factor for the reduction of the duration of the procedure under the decentralized procedure and the mutual recognition procedure is 
the reduction of the period of cooperation of the EU member states. In regards of the centralized procedure, the shortening of the overall duration results 
from the accumulation of several small reductions in time.

Conditional Marketing Authorization

In specific circumstances, EU legislation enables applicants to obtain a conditional marketing authorization prior to obtaining the comprehensive 
clinical data required for an application for a full marketing authorization. The legal basis is Article 14-a of Regulation (EC) No. 726/2004. The provisions 
for granting a conditional marketing authorization are further elaborated in Regulation (EC) No. 507/2006. Such conditional approvals may be granted for 
product candidates (including medicines designated as orphan medicinal products) if the benefit-risk balance of the medicine is positive; it is likely that the 
applicant  will  be  able  to  provide  comprehensive  data  post-authorization;  the  medicine  fulfils  an  unmet  medical  need;  and  the  benefit  of  the  medicine’s 
immediate availability to patients is greater than the risk inherent in the fact that additional data are still required.

A conditional marketing authorization may contain specific obligations to be fulfilled by the marketing authorization holder, including obligations 
with  respect  to  the  completion  of  ongoing  or  new  studies  and  with  respect  to  the  collection  of  pharmacovigilance  data.  Conditional  marketing 
authorizations are valid for one year, and may be renewed annually, if the risk-benefit balance remains positive, and after an assessment of the need for
additional or modified conditions or specific obligations. The timelines for the centralized procedure described above also apply with respect to the review 
by the CHMP of applications for a conditional marketing authorization. In a public health emergency, the conditional marketing authorization procedure 
can also be combined with a rolling review of data during the development of a promising medicine, to further expedite the evaluation.

European Union Regulatory Data Exclusivity

In the EU, new products authorized for marketing (i.e., reference products) qualify for eight years of data exclusivity and an additional two years of 
market exclusivity upon marketing authorization. The data exclusivity period prevents generic or biosimilar applicants from relying on the preclinical and 
clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar marketing authorization in the EU during a 
period of eight years from the date on which the reference product was first authorized in the EU. The market exclusivity period prevents a successful 
generic  or  biosimilar  applicant  from  commercializing  its  product  in  the  EU  until  ten  years  have  elapsed  from  the  initial  authorization  of  the  reference 
product in the EU. The ten-year market exclusivity period can be extended to a maximum of eleven years if, during the first eight years of those ten years, 
the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their 
authorization, are held to bring a significant clinical benefit in comparison with existing therapies.

The planned EU pharmaceutical package mentioned above foresees that pharmaceutical companies are given the opportunity to receive a period of 
protection of up to twelve (12) years (as opposed to the maximum of 11 years currently possible) by achieving certain public health objectives which are as 
follows:

•

•

•

•

two (2) years extension if a pharmaceutical is placed on the market by a company in all Member States within two years, or within three 
years for companies with limited experience in the EU system;

six (6) months extension if the medicinal product covers an unmet medical need;

six (6) months extension if comparative clinical trials are conducted; and

one (1) year extension if a new indication is authorized for the medicinal product within the protection period, provided that a significant 
benefit can be achieved in comparison with existing therapies.

26

 
 
European Union Orphan Designation and Exclusivity

The criteria for designating an orphan medicinal product in the EU are similar in principle to those in the U.S. Under Article 3 of Regulation (EC) 
141/2000,  a  medicinal  product  may  be  designated  as  orphan  if  (1)  it  is  intended  for  the  diagnosis,  prevention  or  treatment  of  a  life-  threatening  or 
chronically debilitating condition, (2) either (a) such condition affects no more than five in 10,000 persons in the EU when the application is made, or (b) 
the product, without the benefits derived from orphan status, would not generate sufficient return in the EU to justify investment and (3) there exists no 
satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will 
be  of  significant  benefit  to  those  affected  by  the  condition.  The  term  ‘significant  benefit’  is  defined  in  Regulation  (EC)  847/2000  to  mean  a  clinically 
relevant advantage or a major contribution to patient care.

Orphan  medicinal  products  are  eligible  for  financial  incentives  such  as  reduction  of  fees  or  fee  waivers  and  are,  upon  grant  of  a  marketing 
authorization, entitled to ten years of market exclusivity for the approved therapeutic indication. During this ten-year market exclusivity period, the EMA 
or the competent authorities of the Member States of the EEA, cannot accept an application for a marketing authorization for a similar medicinal product 
for the same indication. A similar medicinal product is defined as a medicinal product containing a similar active substance or substances as contained in an 
authorized  orphan  medicinal  product,  and  which  is  intended  for  the  same  therapeutic  indication.  This  is  determined  by  the  molecular  structure,  the 
mechanism  of  action  and  the  approved  therapeutic  indication.  The  application  for  orphan  designation  must  be  submitted  before  the  application  for 
marketing authorization. The applicant will receive a fee reduction for the marketing authorization application if the orphan designation has been granted, 
but not if the designation is still pending at the time the marketing authorization is submitted. Orphan designation does not convey any advantage in, or 
shorten the duration of, the regulatory review and approval process.

The ten-year market exclusivity in the EU may be reduced to six years if, at the end of the fifth year, it is established that the product no longer 
meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. On the other 
hand,  orphan  market  exclusivity  can  be  extended  to  a  maximum  of  twelve  years  if  an  approved  pediatric  investigation  plan  (PIP)  has  been  completed. 
Furthermore, marketing authorization may be granted to a similar product for the same indication at any time if:

•

•

•

the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically superior;

the applicant consents to a second orphan medicinal product application; or

the applicant cannot supply enough orphan medicinal product.

The planned EU pharmaceutical package mentioned above provides, among others, for a new regulation to replace Regulation (EC) No. 141/2000 
on orphan medicinal products. The draft regulation introduces the possibility of establishing new designation criteria by the EMA and the restriction of 
designation as an orphan drug to generally seven years. The draft regulation also provides for more flexible rules on the duration of market exclusivity, 
including:  ten  years  of  market  exclusivity  for  orphan  drugs  in  the  case  of  "high  unmet  medical  need",  five  years  for  orphan  drugs,  approved  by  a 
bibliographic marketing authorization and nine years in all other cases with the possibility of extension in the case of market access in all Member States
(another year) or development of new therapeutic indications for an already authorized orphan medicinal product (up to two years). Market exclusivity can 
thus add up to a maximum of thirteen years, whereas today it is still capped at ten years. It should be noted that the market exclusivity right of the orphan 
medicinal product does not prevent the submission, validation and assessment of an application for marketing authorization of a similar medicinal product, 
including generics and biosimilars, if the remaining duration of the market exclusivity right is less than two years. The EU pharmaceutical package is still 
at an early stage of the legislative process. It may still undergo substantial changes and is expected to turn into binding law in several years' time.

Periods of Authorization and Renewals

27

 
 
 
A marketing authorization is valid for five years in principle and the marketing authorization may be renewed after five years on the basis of a re-
evaluation of the risk-benefit balance by the EMA or by the competent authority of the authorizing member state. To this end, the marketing authorization 
holder  must  provide  the  EMA  or  the  competent  authority  with  a  consolidated  version  of  the  file  in  respect  of  quality,  safety  and  efficacy,  including  all 
variations  introduced  since  the  marketing  authorization  was  granted,  at  least  nine  months  before  the  marketing  authorization  ceases  to  be  valid.  Once 
renewed, the marketing authorization is valid for an unlimited period, unless the European Commission or the competent authority decides, on justified 
grounds relating to pharmacovigilance, to proceed with one additional five-year renewal. Any authorization which is not followed by the actual placing of
the drug on the EU market (in case of centralized procedure) or on the market of the authorizing member state within three years after authorization ceases 
to be valid (the so-called sunset clause).

In future, under the planned EU pharmaceutical package mentioned above, pharmaceutical marketing authorizations are to be valid for an unlimited 

period, although a limitation of the duration to five years shall be possible in certain cases. The so-called sunset provision will be abolished.

Rest of the World Regulation

For  other  countries  outside  of  the  EU  and  the  U.S.,  such  as  countries  in  Eastern  Europe,  Latin  America  or  Asia,  the  requirements  governing  the 
conduct  of  clinical  trials,  product  licensing,  pricing  and  reimbursement  vary  from  jurisdiction  to  jurisdiction.  Additionally,  the  clinical  trials  must  be 
conducted  in  accordance  with  cGCP  requirements  and  the  applicable  regulatory  requirements  and  the  ethical  principles  that  have  their  origin  in  the 
Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of 

regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Coverage, Pricing and Reimbursement

Sales of any biopharmaceutical products, if and when approved by FDA or analogous authorities outside the U.S., will depend in significant part on 

the availability of third-party coverage and reimbursement for the products.

In the U.S., third-party payors include government healthcare programs such as Medicare and Medicaid, private health insurers, managed care plans 
and  other  organizations.  These  third-party  payors  are  increasingly  challenging  the  price  and  examining  the  cost-effectiveness  of  medical  products  and 
services,  including  biopharmaceutical  products.  Significant  uncertainty  exists  regarding  coverage  and  reimbursement  for  newly  approved  healthcare 
products. Coverage does not ensure reimbursement. It is time consuming and expensive to seek coverage and reimbursement from third-party payors. We 
may need to conduct expensive pharmacoeconomic studies to demonstrate the medical necessity and cost-effectiveness of our products, in addition to the 
costs required to obtain FDA regulatory approvals. Third-party payors may take into account clinical practice guidelines in determining coverage and there 
may  be  significant  delays  before  our  products  are  addressed  by  such  guidelines  and  we  cannot  predict  what  position  such  guidelines  would  take  with 
respect to our products if and when addressed. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might 
not include all of the approved products for a particular indication, or utilize other mechanisms to manage utilization (such as requiring prior authorization 
for coverage for a product for use in a particular patient). Limits on coverage may impact demand for our products. Even if coverage is obtained, third- 
party reimbursement may not be adequate to allow us to sell our products on a competitive and profitable basis. As result, we may not be sufficient to 
maintain price levels high enough to realize an appropriate return on investment in product development.

In  addition,  in  some  foreign  countries,  the  proposed  pricing  for  a  drug  must  be  approved  before  it  may  be  lawfully  marketed.  The  requirements 
governing drug pricing vary widely from country to country. Some countries provide that drug products may be marketed only after a reimbursement price 
has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of our product candidate to currently 
available  therapies  (so  called  health  technology  assessment,  or  HTA)  in  order  to  obtain  reimbursement  or  pricing  approval.  For  example,  subject  to  the 
requirements set out in Directive 89/105/EEC relating to the transparency of measures regulating the pricing of medicinal products for human use and their 
inclusion in the scope of national health 

28

 
 
insurance systems, EU Member States have the legal competence to set national measures of an economic nature on the marketing of medicinal products in 
order to control public health expenditure on such products. Accordingly, EU Member States can restrict the range of medicinal products for which their 
national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. On December 13, 2021, a new 
Regulation  on  health  technology  assessment  (HTA)  was  adopted  by  the  European  Union.  It  entered  into  force  in  January  2022  and  will  become  fully 
applicable in January 2025. The regulation provides for a coordinated approach to assessing the benefit of new therapies, which assessment will take place 
in parallel to the EU regulatory approval process. The objectives of the EU HTA regulation are to accelerate patient access to new therapies and reduce 
duplication  of  work.  The  impact  of  the  new  legislation  on  market  access,  pricing  and  reimbursement  of  new  medicinal  products  in  the  individual  EU 
countries cannot be predicted yet. An EU Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or 
indirect controls on the profitability of the company placing the medicinal product on the market. Other EU Member States allow companies to fix their 
own  prices  for  drug  products  but  monitor  and  control  prescription  volumes  and  issue  guidance  to  physicians  to  limit  prescriptions.  There  can  be  no 
assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing 
arrangements  for  any  of  our  products.  Historically,  products  launched  in  the  EU  do  not  follow  price  structures  of  the  U.S.  and  generally  tend  to  be 
significantly lower.

The downward pressure on health care costs in general, particularly prescription drugs, has become intense. As a result, increasingly high barriers 
are  being  erected  to  the  entry  of  new  products.  In  addition,  there  can  be  considerable  pressure  by  governments  and  other  stakeholders  on  prices  and 
reimbursement levels, including as part of cost containment measures. Political, economic, and regulatory developments may further complicate pricing 
negotiations,  and  pricing  negotiations  may  continue  after  reimbursement  has  been  obtained.  Reference  pricing  used  by  various  EU  Member  States  and 
parallel import or distribution (arbitrage between low-priced and high-priced member states) can further reduce prices. Any country that has price controls 
or reimbursement limitations for drug products may not allow favorable reimbursement and pricing arrangements.

Other U.S. Health Care Laws and Regulations

In  the  U.S.,  biopharmaceutical  manufacturers  and  their  products  are  subject  to  extensive  regulation  at  the  federal  and  state  level,  such  as  laws 
intended  to  prevent  fraud  and  abuse  in  the  healthcare  industry.  These  laws,  some  of  which  will  apply  only  if  and  when  we  have  an  approved  product, 
include:

•

•

•

•

•

•

federal  false  claims,  false  statements  and  civil  monetary  penalties  laws  prohibiting,  among  other  things,  any  person  from  knowingly 
presenting, or causing to be presented, a false claim for payment of government funds or knowingly making, or causing to be made, a false
statement to get a false claim paid;

federal healthcare program anti-kickback law, which prohibits, among other things, persons from offering, soliciting, receiving or providing 
remuneration, directly or indirectly, to induce either the referral of an individual for, or the purchasing or ordering of, a good or service for 
which payment may be made under federal healthcare programs such as Medicare and Medicaid;

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which, in addition to privacy protections applicable to 
healthcare providers and other entities, prohibits executing a scheme to defraud any healthcare benefit program or making false statements 
relating to healthcare matters;

FDCA, which among other things, strictly regulates drug marketing, prohibits manufacturers from marketing such products prior to approval 
or for off-label use and regulates the distribution of samples;

federal  laws  that  require  pharmaceutical  manufacturers  to  report  certain  calculated  product  prices  to  the  government  or  provide  certain 
discounts  or  rebates  to  government  authorities  or  private  entities,  often  as  a  condition  of  reimbursement  under  government  healthcare
programs;

federal  Open  Payments  (or  federal  “sunshine”  law),  which  requires  pharmaceutical  and  medical  device  companies  to  monitor  and  report 
certain financial interactions with certain healthcare providers to the Center for Medicare & Medicaid Services within the U.S. Department of 
Health  and  Human  Services  for  re-disclosure  to  the  public,  as  well  as  ownership  and  investment  interests  held  by  physicians  and  their 
immediate family members;

29

 
 
•

•

•

•

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm 
consumers;

analogous state laws and regulations, including: state anti-kickback and false claims laws; state laws requiring pharmaceutical companies to 
comply  with  specific  compliance  standards,  restrict  financial  interactions  between  pharmaceutical  companies  and  healthcare  providers  or 
require  pharmaceutical  companies  to  report  information  related  to  payments  to  health  care  providers  or  marketing  expenditures;  and  state 
laws  governing  privacy,  security  and  breaches  of  health  information  in  certain  circumstances,  many  of  which  differ  from  each  other  in 
significant ways and often are not preempted by HIPAA, thus complicating compliance efforts;

the Travel Act of 1961, which has been used as a tool in the health care context to target kickback schemes involving private insurance that 
would not otherwise be prohibited under the anti-kickback statute, makes it unlawful for a facility to use interstate commerce with the intent, 
among other things, to distribute proceeds of “unlawful activity” and thereafter do some act to further such distribution (“unlawful activity” 
includes bribery under the state law in which the activity was committed); and

laws and regulations prohibiting bribery and corruption, such as the FCPA, which, among other things, prohibits U.S. companies and their 
employees and agents from authorizing, promising, offering, or providing, directly or indirectly, corrupt or improper payments or anything 
else  of  value  to  foreign  government  officials,  employees  of  public  international  organizations  or  foreign  government-owned  or  affiliated 
entities, candidates for foreign public office, and foreign political parties or officials thereof.

Violations of these laws are punishable by criminal and/or civil sanctions, including, in some instances, exclusion from participation in federal and 

state health care programs, such as Medicare and Medicaid. Ensuring compliance is time consuming and costly.

Similar  healthcare  laws  and  regulations  exist  in  the  EU  and  other  jurisdictions,  including  reporting  requirements  detailing  interactions  with  and 

payments to healthcare providers and laws governing the privacy and security of personal information.

Health Care Reform in the U.S. and Potential Changes to Health Care Laws

Health care reform has been a significant trend in the U.S. health care industry and elsewhere. In particular, government authorities and other third-
party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medical products and services. Under the 
Trump administration, there were efforts to repeal or modify prior health care reform legislation and regulation and to implement new health care reform 
measures, including measures related to payment for drugs under government health care programs. The Biden administration ceased many of these efforts, 
but  continued  others,  such  as  implementing  mandatory  price  transparency  for  providers  and  insurance  companies.  The  nature  and  scope  of  health  care 
reform in the wake of the 2024 election remains uncertain.

There has been heightened governmental scrutiny in recent years over the manner in which manufacturers set prices for their marketed products, 
which has resulted in proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing and 
reform government program reimbursement methodologies for pharmaceutical and biologic products. At the state level, individual states are increasingly 
passing  legislation  and  implementing  regulations  designed  to  control  pharmaceutical  and  biological  product  pricing,  including  price  or  patient 
reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, 
designed  to  encourage  importation  from  other  countries  and  bulk  purchasing.  These  measures  could  reduce  the  ultimate  demand  for  our  products,  once 
approved, or put pressure on our product pricing.

We  cannot  predict  the  likelihood,  nature  or  extent  of  government  regulation  that  may  arise  from  future  legislation  or  administrative  or  executive 
action, either in the U.S. or abroad. We expect that additional federal and state health care reform measures will be adopted in the future, any of which 
could limit the amounts that federal and state governments will pay for health care products and services.

Data Privacy Regulation

U.S. Privacy Law

There are numerous U.S. federal and state laws and regulations related to the privacy and security of personal information, including laws requiring 
the safeguarding of personal information and laws requiring notification to governmental authorities and data subjects as well as remediation in the event of 
a data breach. In the health care industry generally, under the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended 
in 2009 by the Health Information Technology for Economic and Clinical Health Act, or HITECH, the U.S. Department of Health and Human Services, or 
HHS,  has  issued  regulations  to  protect  the  privacy  and  security  of  protected  health  information  used  or  disclosed  by  covered  entities  including  certain 
healthcare  providers,  health  plans  and  healthcare  clearinghouses.  HIPAA  also  regulates  standardization  of  data  content,  codes  and  formats  used  in 
healthcare transactions and standardization of identifiers for health plans and providers. HIPAA also imposes certain obligations on the business associates 
of covered entities that obtain protected health information in providing services to or on behalf of covered entities. HIPAA may apply to us in certain 
circumstances and may also apply to our business partners in ways that may impact our relationships with them. Our clinical trials are regulated by the 
Common Rule, which also includes specific privacy-related provisions. HITECH made significant modifications to HIPAA including subjecting business 
associates to direct regulation and enforcement by the Office of Civil Rights of HHS, or OCR, instituting a breach notification requirement for breaches of
unsecured PHI, including a breach of PHI held by a business associate, and strengthening the enforcement tools available to OCR. In addition to federal 
privacy regulations, there are a number of state laws governing confidentiality and security of health information that may be applicable to our business. In 
addition  to  possible  federal  civil  and  criminal  penalties  for  HIPAA  violations,  state  attorneys  general  are  authorized  to  file  civil  actions  for  damages  or 
injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, state attorneys 
general (along with private plaintiffs) have brought civil actions seeking injunctions and damages resulting from alleged violations of HIPAA’s privacy and 
security rules. State attorneys general also have authority to enforce state privacy and security laws.

General Data Protection Regulation

Many countries outside of the U.S. maintain rigorous laws governing the privacy and security of personal information. The General Data Protection 
Regulation,  (EU)  2016/679,  or  GDPR,  became  effective  on  May  25,  2018,  and  deals  with  the  collection,  use,  storage,  disclosure,  transfer,  or  other 
processing of personal data, including personal health data, regarding individuals in the EEA. The GDPR imposes a broad range of strict requirements on 
companies  subject  to  the  GDPR,  including  requirements  relating  to  having  legal  bases  for  processing  personal  information  relating  to  identifiable 
individuals and transferring such information outside the EEA, including to the U.S., providing details to those individuals regarding the processing of their 
personal health and other sensitive data, obtaining consent to certain processing activities from the individuals to whom the personal data relates, keeping 
personal data secure, having data processing agreements with third parties who process personal data, responding to individuals’ requests to exercise their 
rights in respect of their personal data, reporting security breaches involving personal data to the competent national data protection authority and affected 
individuals, appointing data protection officers, conducting data protection impact assessments, and record- keeping. The GDPR provides for substantial 
penalties to which we could be subject in the event of any non-compliance, including fines of up to €10 million or up to two percent of our total worldwide 
annual revenues, whichever is greater, for certain comparatively minor offenses, or up to €20 million or up to four percent of our total worldwide annual 
revenues, whichever is greater, for more serious offenses. The GDPR also confers a private right of action on data subjects and consumer associations to 
lodge  complaints  with  supervisory  authorities,  seek  judicial  remedies,  and  obtain  compensation  for  damages  resulting  from  violations  of  the  GDPR.  In 
addition, the GDPR includes restrictions on cross-border data transfers, and recent court decisions and regulatory guidance have substantially increased the 
compliance burden and legal uncertainty associated with transferring the personal data of EEA individuals to third countries outside of the EEA whose data 
protection laws are not believed to be adequate by European standards (although the recent EU-US Data Privacy Framework offers a new route for data 
transfers from the EU to be made lawfully to the US). 

31

 
 
Further, the GDPR provides for opening clauses in certain areas, which enable the legislators of member states of the EU to implement additional 
requirements to the GDPR in national law, whereby national laws may partially deviate from the GDPR and impose different obligations from country to 
country, so that we do not expect to operate in a uniform legal landscape in the EEA.

Also, as it relates to processing and transfer of genetic, biometric and health data, the GDPR specifically allows national laws to impose additional 
and  more  specific  requirements  or  restrictions,  and  European  laws  have  historically  differed  quite  substantially  in  this  field,  leading  to  additional 
uncertainty. The UK’s decision to leave the EU (and it is important to note that the EEA does not include the UK), often referred to as Brexit, has created 
uncertainty with regard to data protection regulation in the UK and to what extent UK law will diverge from the GDPR in the future. At this point in time, 
the UK Government has incorporated the GDPR into UK law, known as the ‘UK GDPR', but has also published proposals recently to reform UK data 
protection  law  which  are  going  through  the  UK  Parliament  and  likely  to  become  law  in  2024.  In  the  context  of  international  data  transfers,  European 
Commission  has  issued  adequacy  decisions  which  have  the  effect  of  authorizing  data  transfers  from  the  EEA  to  the  UK.  The  UK  Government  and  the 
Information Commissioner’s Office have also published proposals recently to indicate how data transfers between the UK and the rest of the world will be 
regulated now that the UK has left the EU. For instance, the UK Government proposes recognizing more countries as adequate for data transfers as part of 
reducing barriers to data flows — this would include countries not yet authorized by the European Commission. The UK Government has also approved 
the UK Extension to the EU-US Data Privacy Framework for data transfers from the UK to the US.

Employees and Human Capital Resources 

As  of  December  31,  2023,  we  had  15  full-time  employees,  including  a  total  of  five  employees  with  M.D.  or  Ph.D.  degrees.  Of  these  full-time 
employees, six are engaged in research and development activities and nine are engaged in general and administrative activities. None of our employees is 
represented by a labor union or covered by a collective bargaining agreement. 

We are dedicated to fostering a workplace environment that keeps our employees inspired, including providing a comprehensive benefits program 
that supports the health care, family, and financial needs of our employees. All of our full-time employees are eligible for cash bonuses and equity awards 
in addition to other benefits including comprehensive health insurance, life and disability insurance, and 401(k) matching.

Item 1A. Risk Factors.

Careful consideration should be given to the following risk factors, in addition to the other information set forth in this Annual Report on Form 10-
K and in other documents that we file with the SEC, in evaluating our company and our business. Investing in our common stock involves a high degree of 
risk. If any of the following risks actually occur, our business, financial condition, results of operations and future growth prospects could be materially and 
adversely affected.

Risks Related to Our Business 

Our  business  is  highly  dependent  on  the  success  of  our  product  candidates,  LTI-03  and  LTI-01  and  any  other  product  candidates  that  we 
advance  into  clinical  development.  Our  approach  to  drug  discovery  and  development  in  the  area  of  fibrotic  diseases,  with  a  focus  on  Cav1-related 
peptides, is unproven and may not result in marketable products. All of our product candidates will require significant additional development before 
we may be able to seek regulatory approval for and launch a product commercially. Raising additional capital may cause dilution to our stockholders, 
restrict our operations or require us to relinquish rights to LTI-03, LTI-01, or other product candidates. 

We currently have no products that are approved for commercial sale and may never be able to develop marketable products. We have two clinical 
product candidates, LTI-03 and LTI-01, in early- and mid-stage clinical development, respectively. If either of our clinical product candidates encounter
safety or efficacy problems, development delays, regulatory issues or other problems, our development plans and business would be significantly harmed. 
We have completed a Phase 1a safety and tolerability clinical trial of LTI-03 in healthy normal volunteers and are currently recruiting a Phase 1b dose 
ranging,  placebo-controlled  safety  and  tolerability  trial  of  LTI-03  in  IPF  patients.  We  have  completed  a  Phase  1b  safety,  tolerability  and  proof  of 
mechanism  trial  and  a  Phase  2a  dose-ranging,  placebo-controlled  trial  of  LTI-01  in  loculated  pleural  effusion,  or  LPE,  patients.  We  must  successfully 
complete Phase 3 clinical trials prior to obtaining FDA approval of LTI-03 or LTI-01 for commercial use. 

For each product candidate, we must demonstrate its safety and efficacy in humans, obtain regulatory approval in one or more jurisdictions, obtain 
manufacturing supply, capacity and expertise, and substantially invest in marketing efforts before we are able to generate any revenue from such product 
candidate. 

Before we can generate any revenue from sales of our clinical product candidates, LTI-03 and LTI-01, or any other product candidates, we must 
perform additional clinical studies and/or preclinical development, and complete regulatory review and approval in one or more jurisdictions. In addition, if 
one  or  more  of  our  product  candidates  is  approved,  we  must  ensure  sufficient  commercial  manufacturing  capacity  and  conduct  and  finance  significant 
marketing efforts in connection with any commercial launch. These efforts will require substantial investment, and we may not have the financial resources 
to continue development of our product candidates. 

We may experience setbacks that could delay or prevent regulatory approval of, or our ability to commercialize, our product candidates, including, 

but not limited to: 

•

•

•

•

•

•

negative or inconclusive results from our clinical trials or preclinical studies or the clinical trials or preclinical studies of others for product 
candidates  similar  to  ours,  leading  to  a  decision  or  requirement  to  conduct  additional  clinical  trials  or  preclinical  studies  or  to  abandon  a 
program; 

drug-related  side  effects  experienced  by  subjects  in  our  clinical  trials  or  by  individuals  using  drugs  or  therapeutics  similar  to  our  product 
candidates; 

delays in submitting Investigational New Drug applications, or INDs, or comparable foreign regulatory applications or delays or failure in 
obtaining  the  necessary  approvals  from  regulators  to  commence  a  clinical  trial,  or  a  suspension  or  termination  of  a  clinical  trial  once 
commenced; 

conditions imposed by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials or our drug development 
strategy; 

delays in enrolling subjects in clinical trials; 

high drop-out rates of subjects from clinical trials; 

33

 
 
•

•

•

•

•

•

•

•

inadequate or delayed supply or quality of product candidates or other materials necessary for the conduct of our clinical trials; 

greater than anticipated clinical trial costs; 

inability to compete with other therapies; 

unfavorable FDA or other regulatory agency inspection and review of a clinical trial site; 

failure  of  our  third-party  manufacturers,  contractors  or  investigators  to  comply  with  regulatory  requirements  or  otherwise  meet  their 
contractual obligations in a timely manner, or at all; 

delays in obtaining any pre-market inspections required by the FDA or other regulatory agencies; 

delays  and  changes  in  regulatory  requirements,  policy  and  guidelines,  including  the  imposition  of  additional  regulatory  oversight  around 
clinical testing generally or with respect to our technology in particular; or 

varying interpretations of data by the FDA and similar foreign regulatory agencies. 

We do not have complete control over many of these factors, including certain aspects of clinical development and the regulatory review process, 

potential threats to our intellectual property rights and our manufacturing, marketing, distribution and sales efforts or that of any future collaborator. 

Our approach to drug research and development in the area of fibrotic diseases, with a focus on Cav1-related peptides, is unproven and may not 

result in marketable products. 

Our approach is to develop targeted treatments for fibrosis with an initial focus on Cav1 biology and utilization of its caveolin scaffolding domain, 
or  CSD,  peptide  region.  However,  to  date,  this  mechanism  has  not  been  definitively  proven  to  successfully  treat  fibrosis  in  patients.  Utilizing  a  Cav1-
related peptide to treat fibrosis is a novel approach in a rapidly developing field, and there can be no assurance that we will not experience unforeseen 
problems or delays in developing our product candidates, that such problems or delays will not result in unanticipated costs, or that any such development 
problems can be solved. Therefore, we may ultimately discover that our approach and any product candidates resulting therefrom do not possess properties 
required for therapeutic effectiveness. As a result, we may never succeed in developing a marketable product. 

In addition, while we have utilized cell assays, precision cut lung slice models, and in vivo animal models to assess both anti-fibrotic and epithelium 

preservation functions of Cav1-related peptides, there can be no assurance that our technology will yield its intended benefits in human patients. 

Risks Related to Our Financial Condition 

We  will  require  substantial  additional  capital  to  finance  our  operations.  Our  cash  and  cash  equivalents  are  not  sufficient  to  enable  us  to 
complete the development and commercialization of LTI-03 and LTI-01. If we are unable to raise such capital when needed, or on acceptable terms, we 
may be forced to delay, reduce and/or eliminate one or more of our clinical and research and development programs, future commercialization efforts 
or other operations. 

Developing  biopharmaceutical  products,  including  conducting  clinical  trials  and  preclinical  studies,  is  a  very  time-consuming,  expensive  and 
uncertain  process  that  takes  years  to  complete.  Our  operations  have  consumed  substantial  amounts  of  cash  since  inception.  We  expect  our  expenses  to 
increase  in  connection  with  our  ongoing  activities,  particularly  as  we  conduct  our  planned  clinical  trials  of  LTI-03  and  LTI-01  and  any  future  product 
candidates that we may develop, seek regulatory approvals for our product candidates and to launch and commercialize any products for which we receive 
regulatory approval. Accordingly, we will need to obtain substantial additional funding in order to maintain our continuing operations. If we are unable to 
raise  capital  when  needed  or  on  acceptable  terms,  we  may  be  forced  to  delay,  reduce  or  eliminate  one  or  more  of  our  research  and  drug  development 
programs or future commercialization efforts. 

34

 
 
As of December 31, 2023, we had approximately $17.3 million in cash and cash equivalents. Based on our current operating plan, we believe that 
existing cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2024. 
However, our future capital requirements and the period for which our existing resources will support our operations may vary significantly from what we 
expect, and we will in any event require additional capital in order to complete clinical development of any of our current programs. Our monthly spending 
levels will vary based on new and ongoing development and corporate activities. Because the length of time and activities associated with development of 
our product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development, marketing and commercialization 
activities. Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to: 

•

•

•

•

•

•

•

•

•

•

•

the initiation, progress, timing, costs and results of clinical trials and preclinical studies for our product candidates; 

the clinical development plans we establish for these product candidates; 

the timelines of our clinical trials and the overall costs to finish the clinical trials; 

the number and characteristics of product candidates that we develop; 

the  outcome,  timing  and  cost  of  meeting  regulatory  requirements  established  by  the  FDA,  and  other  comparable  foreign  regulatory 
authorities; 

whether we are able to enter into collaboration agreements and the terms of any such agreements; 

the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights; 

the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us or our product 
candidates; 

the effect of competing technological and market developments; 

the cost and timing of completion of outsourced manufacturing activities; and 

the  cost  of  establishing  sales,  marketing  and  distribution  capabilities  for  any  product  candidates  for  which  we  may  receive  regulatory 
approval in regions where we choose to commercialize our products on our own. 

We  do  not  have  any  committed  external  source  of  funds  or  other  support  for  our  development  efforts  and  we  cannot  be  certain  that  additional 
funding will be available on acceptable terms, or at all. Until we can generate sufficient revenue to finance our cash requirements, which we may never do, 
we expect to finance our future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, 
licensing arrangements and other marketing or distribution arrangements. If we raise additional funds through public or private equity offerings, the terms 
of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Further, to the extent that we 
raise additional capital through the sale of common stock or securities convertible or exchangeable into common stock, your ownership interest will be 
diluted. In addition, any debt financing may subject us to fixed payment obligations and covenants limiting or restricting our ability to take specific actions, 
such  as  incurring  additional  debt,  making  capital  expenditures  or  declaring  dividends.  If  we  raise  additional  capital  through  marketing  and  distribution 
arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable intellectual 
property or other rights to our product candidates, technologies, future revenue streams or research programs or grant licenses on terms that may not be 
favorable to us. We also may be required to seek collaborators for any of our product candidates at an earlier stage than otherwise would be desirable or 
relinquish our rights to product candidates or technologies that we otherwise would seek to develop or commercialize ourselves. Any of the above events 
could significantly harm our business, prospects, financial condition and results of operations and cause the price of our common stock to decline. 

There is no guarantee that our acquisition of Lung and its business will increase stockholder value in our company or that we will be able to 

realize the anticipated benefits of the acquisition. 

35

 
 
In October 2023, we acquired Lung and shifted our disease focus from chemoprotection to orphan pulmonary and fibrosis indications. We cannot 
guarantee that implementing the Lung Acquisition and related transactions and the shift in our disease focus will not impair stockholder value or otherwise 
adversely affect our business or that we will be able to realize the anticipated benefits of the acquisition. The Lung Acquisition poses significant integration 
challenges between our business and management teams which could result in management and business disruptions, any of which could harm our results 
of operation, business prospects, and impair the value of such acquisition to our stockholders. 

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to LTI-03, LTI-01 or 

other product candidates. 

We expect our expenses to increase as we will incur significant research and development expenses as we continue our ongoing clinical trial of LTI-
03  in  patients  with  IPF,  continue  our  non-clinical  research  with  our  product  candidates,  initiate  additional  clinical  trials  of  our  product  candidates  and 
pursue later stages of clinical development of our product candidates. Until such time, if ever, as we can generate substantial revenues from the sale of our 
products, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances and/or licensing 
arrangements.  To  the  extent  that  we  raise  additional  capital  through  the  sale  of  equity  or  convertible  debt  securities,  the  ownership  interest  of  our  then 
existing stockholders may be diluted, and the terms of these securities could include liquidation or other preferences and anti-dilution protections that could 
adversely affect the rights of our common stockholders. In addition, debt financing, if available, would result in fixed payment obligations and may involve 
agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures, 
creating liens, redeeming stock or declaring dividends, that could adversely impact our ability to conduct our business. Securing financing may also require 
a substantial amount of time and attention from our management team and could divert a disproportionate amount of their attention away from day-to-day 
activities, which may adversely affect our management’s ability to oversee the development of our product candidates. 

We may seek one or more collaborators for future development of our product candidates for one or more indications. However, we may not be able 
to enter into such collaborations on suitable terms, on a timely basis, or at all. Even if we are able to raise additional funds through collaborations, strategic 
alliances  or  licensing  arrangements  with  third  parties,  we  may  have  to  relinquish  valuable  rights  to  our  technology,  future  revenue  streams  or  product 
candidates or grant licenses on terms that may not be favorable to us. 

If we are unable to raise additional funds when needed, we may be required to delay, reduce and/or eliminate our product development or future 

commercialization efforts, or grant rights to develop and market product candidates that we might otherwise prefer to develop and market ourselves. 

We have a limited operating history and no products approved for commercial sale, which may make it difficult to evaluate our prospects and 

likelihood of success. 

We are a clinical-stage biopharmaceutical company with a limited operating history. We have no products approved for commercial sale and have 
not generated any revenue from product sales. Our operations to date have been limited to organizing and staffing our company, business planning, raising 
capital, establishing our intellectual property portfolio and performing clinical trials and research and development of our product candidates. Our approach 
to the research and development of product candidates is unproven, and we do not know whether we will be able to develop any products of commercial 
value. In addition, one clinical product candidate, LTI-03, is in early clinical development and a second clinical product candidate, LTI-01, is in mid-stage 
clinical development. Both programs will require substantial additional development and clinical research time and resources before we would be able to 
apply  for  or  receive  regulatory  approvals  and  begin  generating  revenue  from  product  sales.  We  have  not  yet  demonstrated  the  ability  to  progress  any 
product  candidate  through  clinical  trials  to  regulatory  approval.  We  are  still  in  mid-stage  and  early  clinical  development  and  may  be  unable  to  obtain 
regulatory approval, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities 
necessary  for  successful  product  commercialization.  Investment  in  biopharmaceutical  product  development  is  highly  speculative  because  it  entails 
substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate efficacy or an acceptable 
safety profile, gain regulatory approval and become commercially viable. In addition, as a business with a limited operating history, we may encounter 
unforeseen 

36

 
 
expenses,  difficulties,  complications,  delays  and  other  known  and  unknown  factors  and  risks  frequently  experienced  by  early-stage  biopharmaceutical 
companies  in  rapidly  evolving  fields.  Consequently,  we  have  no  meaningful  history  of  operations  upon  which  to  evaluate  our  business,  and  predictions 
about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and 
commercializing drug products. 

We have incurred significant net losses since inception and we expect to continue to incur significant net losses for the foreseeable future and do 
not  expect  to  achieve  or  maintain  profitability.  Even  if  we  are  able  to  develop  and  commercialize  our  product  candidates,  we  may  never  generate 
revenues that are significant or large enough to achieve profitability. 

We have incurred significant losses since our inception and have financed our operations principally through equity financings. We continue to incur 
significant research and development and other expenses related to our ongoing operations. For the years ended December 31, 2023 and 2022, we reported 
an operating loss of $16.3 million and $27.6 million, respectively. As of December 31, 2023, we had an accumulated deficit of $288.5 million. We have 
devoted substantially all of our resources and efforts to organizing and staffing our company, business planning, raising capital, acquiring and discovering 
development programs, securing intellectual property rights and research and development and we expect that it will be several years, if ever, before we 
generate revenue from product sales. Even if we receive marketing approval for and commercialize one or more of our product candidates, we expect that 
we will continue to incur substantial research and development and other expenses in order to develop and market additional potential product candidates. 
We expect to continue to incur significant losses for the foreseeable future, and we anticipate that our expenses will increase substantially if, and as, we: 

•

•

•

•

•

•

•

•

•

•

•

advance  the  development  of  our  clinical  product  candidates,  LTI-03  and  LTI-01,  and  our  other  product  candidates,  through  clinical 
development, and, if successful, later-stage clinical trials; 

advance our preclinical development programs into clinical development; 

research and develop new product candidates; 

experience  delays  or  interruptions  to  clinical  trials,  preclinical  studies,  our  receipt  of  materials  and  services  from  our  third-party  service 
providers on whom we rely, or our supply chain; 

seek regulatory approvals for any product candidates that successfully complete clinical trials; 

commercialize our product candidates and any future product candidates, if approved; 

increase the amount of research and development activities to identify and develop product candidates;

hire additional clinical, chemistry, manufacturing, controls, or CMC, quality control, scientific and management personnel and expand our 
operational, financial and management systems and personnel, including personnel to support our clinical development and manufacturing 
efforts and our operations as a public company; 

establish a sales, marketing, medical affairs and distribution infrastructure to commercialize any products for which we may obtain marketing 
approval and intend to commercialize on our own or jointly with third parties; 

maintain, expand and protect our intellectual property portfolio; and 

invest in or in-license other technologies or product candidates. 

To become and remain profitable, we must develop and eventually commercialize products with significant market potential. This will require us to 
be  successful  in  a  range  of  challenging  activities,  including  completing  clinical  trials  and  preclinical  studies,  obtaining  marketing  approval  for  product 
candidates, manufacturing, marketing and selling products for which we may obtain marketing approval and satisfying any post-marketing requirements. 
We may never succeed in any or all of these activities and, even if we do, we may never generate revenue that is significant enough to achieve profitability. 
If  we  do  achieve  profitability,  we  may  not  be  able  to  sustain  or  increase  profitability  on  a  quarterly  or  annual  basis.  Our  failure  to  become  and  remain 
profitable would decrease the value of our company 

37

 
 
and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. 

We hold a portion of our cash and cash equivalents that we use to meet our working capital and operating expense needs in deposit accounts 

that could be adversely affected if the financial institutions holding such funds fail. 

We  hold  a  portion  of  cash  and  cash  equivalents  that  we  use  to  meet  our  working  capital  and  operating  expense  needs  in  deposit  accounts.  The 
balance held in these accounts may exceed the Federal Deposit Insurance Corporation, or FDIC, standard deposit insurance limit of $250,000. If a financial 
institution in which we hold such funds fails or is subject to significant adverse conditions in the financial or credit markets, we could be subject to a risk of 
loss of all or a portion of such uninsured funds or be subject to a delay in accessing all or a portion of such uninsured funds. Any such loss or lack of access 
to these funds could adversely impact our short term liquidity and ability to meet our operating expense obligations. 

For example, on March 10, 2023, Silicon Valley Bank, or SVB, and Signature Bank, were closed by state regulators and the FDIC was appointed 
receiver for each bank. The FDIC created successor bridge banks and all deposits of SVB and Signature Bank were transferred to the bridge banks under a 
systemic risk exception approved by the United States Department of the Treasury, the Federal Reserve and the FDIC. If financial institutions in which we 
hold funds for working capital and operating expenses were to fail, we cannot provide any assurances that such governmental agencies would take action to 
protect our uninsured deposits in a similar manner. 

We  also  maintain  investment  accounts  in  which  we  hold  our  investments  and,  if  access  to  the  funds  we  use  for  working  capital  and  operating 
expenses is impaired, we may not be able to open new operating accounts or to sell investments or transfer funds from our investment accounts to new 
operating accounts on a timely basis sufficient to meet our operating expense obligations. 

We have identified conditions that raise substantial doubt about our ability to continue as a going concern and if we are unable to continue as a

going concern, we may have to liquidate, dissolve or seek bankruptcy protection.

We do not believe that our cash and cash equivalents as of the date of this Annual Report on Form 10-K will be sufficient to enable us to fund our 
current operations for at least twelve months from the date of issuance of the financial statements included in this Annual Report on Form 10-K and have 
therefore concluded that this circumstance raises substantial doubt about our ability to continue as a going concern. See Note 1 to our consolidated financial 
statements  appearing  elsewhere  in  this  Annual  Report  on  Form  10-K  for  additional  information  on  our  assessment.  We  expect  that  we  will  continue  to 
generate substantial operating losses for the foreseeable future until we complete development and approval of our product candidates.

Our consolidated financial statements have been prepared assuming that we will continue to operate as a going concern, which contemplates the 
continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. After the Lung Acquisition, we believe 
that, based on our current operating plan, our cash and cash equivalents as of December 31, 2023, will enable us to fund our operating expenses and capital 
expenditure requirements into the fourth quarter of 2024 following the date of this Annual Report on Form 10-K.

Since  our  inception,  we  have  not  generated  any  revenue  from  product  sales  and  have  never  generated  an  operating  profit.  We  have  incurred 
significant losses on an aggregate basis. These losses have resulted primarily from costs incurred in connection with research and development activities, 
licensing and patent investment and general and administrative costs associated with our operations. In February 2023, we discontinued development of 
ALRN-6924  which  substantially  reduced  our  operating  expenses.  Notwithstanding  these  events,  we  expect  to  continue  to  incur  operating  losses  for  the 
foreseeable  future  unless  we  complete  development  and  approval  of  our  product  candidates.  We  will  continue  to  fund  our  operations  primarily  through 
utilization of our current financial resources and additional raises of capital.

38

 
 
These conditions raise substantial doubt about our ability to continue as a going concern as of the date of this Annual Report on Form 10-K. We plan 
to  address  these  conditions  by  raising  funds  from  our  current  investors,  potential  outside  investors  and  other  funding  sources.  However,  there  is  no 
assurance that such funding will be available to us, will be obtained on terms favorable to us or will provide us with sufficient funds to meet our objectives. 
The  reaction  of  investors  to  the  inclusion  of  a  going  concern  statement  by  our  auditors  and  our  potential  inability  to  continue  as  a  going  concern  may 
materially adversely affect our share price and our ability to raise new capital or enter into partnerships. Our funding estimates are based on assumptions 
that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Our future viability is dependent on our 
ability to raise additional capital, enter into a financing, consummate a successful acquisition, merger, business combination, or a sale of assets or other 
transaction. If we become unable to continue as a going concern, we may have to:

•

•

•

•

•

significantly delay, scale back, or discontinue the development or commercialization of our product candidates;

seek strategic partnerships, or amend existing partnerships, for research and development programs at an earlier stage than otherwise would 
be desirable or that we otherwise would have sought to develop independently, or on terms that are less favorable than might otherwise be 
available in the future;

dispose of technology assets, or relinquish or license on unfavorable terms, our rights to technologies or any of our product candidates that 
we otherwise would seek to develop or commercialize ourselves;

liquidate our assets and the values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected 
in our consolidated financial statements; or

file for bankruptcy or cease operations altogether (and face any related legal proceedings).

Any of these events could have a material adverse effect on our business, operating results and prospects.

We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the 
future or fail to maintain an effective system of internal control over financial reporting, which may result in material misstatements of our financial 
statements or cause us to fail to meet our periodic reporting obligations.

Effective  internal  control  over  financial  reporting  is  necessary  for  us  to  provide  reliable  financial  reports  and,  together  with  adequate  disclosure 
controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties encountered in their 
implementation could cause us to fail to meet our reporting obligations. In addition, any testing by us conducted in connection with Section 404 of the
Sarbanes-Oxley Act, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal control over 
financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify 
other areas for further attention or improvement. An ineffective system of internal control could also cause investors to lose confidence in our reported 
financial information, which could have a negative effect on the trading price of our stock.

We  have  identified  material  weaknesses  in  our  internal  control  over  financial  reporting  as  of  December  31,  2023.  A  material  weakness  is  a 
deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a possibility that a material misstatement of our 
financial  statements  will  not  be  prevented  or  detected  on  a  timely  basis.  The  material  weaknesses  primarily  related  to  the  accounting  for  the  business 
combination with Lung Therapeutics, Inc., specifically the (i) lack of sufficient accounting and supervisory personnel to maintain appropriate segregation 
of duties relating to user access of the financial accounting system and who have the appropriate level of technical accounting experience and training, (ii) 
lack of evidence over reviews of account reconciliations and supporting schedules, and (iii) lack of adequate procedures and controls to ensure that accurate 
financial  statements  could  have  been  prepared  and  reviewed  on  a  timely  basis  for  annual  reporting  purposes.  Refer  to  Part  II,  Item  9A  for  additional 
information regarding the material weaknesses. 

We  are  implementing  procedures  to  remediate  these  material  weaknesses,  however,  we  cannot  assure  you  that  these  or  other  measures  will  fully 

remediate the material weaknesses in a timely manner or prevent future material weaknesses from occurring.  

39

 
 
If we identify material weaknesses in the future, and we are unable to remediate any such material weaknesses, our reputation, financial reporting 
and  condition,  and  operating  results  could  suffer.  Moreover,  we  could  become  subject  to  investigations  by  regulatory  authorities,  which  could  require 
additional financial and management resources. 

We  are  required  to  disclose  changes  made  in  our  internal  control  procedures  on  a  quarterly  basis.  Our  management  is  required  to  assess  the 
effectiveness of these controls annually. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are required to furnish a report by 
our  management  on  our  internal  control  over  financial  reporting.  However,  for  so  long  as  we  are  neither  a  “large  accelerated  filer”  nor  an  “accelerated 
filer”,  we  will  not  be  required  to  include  an  attestation  report  on  internal  control  over  financial  reporting  issued  by  our  independent  registered  public 
accounting  firm.  An  independent  assessment  of  the  effectiveness  of  our  internal  control  over  financial  reporting  could  detect  additional  material 
weaknesses that our management’s assessment might not detect. Undetected material weaknesses in our internal control over financial reporting could lead 
to restatements of our financial statements and require us to incur the expense of remediation.

During  the  course  of  our  review  and  testing,  we  may  identify  additional  material  weaknesses  and  be  unable  to  remediate  them  before  we  must 
provide the required reports. Furthermore, if we identify any material weaknesses, we may not detect errors on a timely basis and our financial statements 
may be materially misstated.

The amount of our future losses is uncertain and our quarterly operating results may fluctuate significantly or may fall below the expectations 

of investors or securities analysts, each of which may cause our stock price to fluctuate or decline. 

Our quarterly and annual operating results may fluctuate significantly in the future due to a variety of factors, many of which are outside of our 

control and may be difficult to predict, including the following: 

•

•

•

•

•

•

•

•

•

•

•

•

the  timing  and  success  or  failure  of  clinical  trials  for  our  product  candidates  or  competing  product  candidates,  or  any  other  change  in  the 
competitive landscape of our industry, including consolidation among our competitors or partners; 

our ability to successfully recruit and retain subjects for clinical trials, and any delays caused by difficulties in such efforts; 

our ability to obtain marketing approval for our product candidates, and the timing and scope of any such approvals we may receive; 

the timing and cost of, and level of investment in, research and development activities relating to our product candidates, which may change 
from time to time; 

the cost and timing of manufacturing our product candidates, which may vary depending on the quantity of production and the terms of our 
agreements with manufacturers; 

our ability to attract, hire and retain qualified personnel; 

expenditures that we will or may incur to develop additional product candidates; 

the level of demand for our product candidates should they receive approval, which may vary significantly; 

the risk/benefit profile, cost and reimbursement policies with respect to our product candidates, if approved, and existing and potential future 
therapeutics that compete with our product candidates; 

general market conditions or extraordinary external events, such as recessions or pandemics; 

the changing and volatile U.S. and global economic environments; and 

future accounting pronouncements or changes in our accounting policies. 

The  cumulative  effects  of  these  factors  could  result  in  large  fluctuations  and  unpredictability  in  our  quarterly  and  annual  operating  results.  As  a 
result, comparing our operating results on a period-to-period basis may not be meaningful. This variability and unpredictability could also result in our 
failing to meet the expectations of industry or financial analysts or investors for any period. If our revenue or operating results fall below the expectations 
of 

40

 
 
analysts  or  investors  or  below  any  forecasts  we  may  provide  to  the  market,  or  if  the  forecasts  we  provide  to  the  market  are  below  the  expectations  of 
analysts  or  investors,  the  price  of  our  common  stock  could  decline  substantially.  Such  a  stock  price  decline  could  occur  even  when  we  have  met  any 
previously publicly stated guidance we may provide. 

Risks Related to the Discovery, Development and Commercialization of Product Candidates 

The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, interim results of a clinical 
trial, do not necessarily predict final results and the results of our clinical trials may not satisfy the requirements of the FDA or comparable foreign 
regulatory authorities. 

We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. Clinical failure can occur at 
any  stage  of  clinical  development.  Clinical  trials  may  produce  negative  or  inconclusive  results,  and  we  or  any  future  collaborators  may  decide,  or 
regulatory  authorities  may  require  us,  to  conduct  additional  clinical  trials  or  nonclinical  studies.  We  will  be  required  to  demonstrate  with  substantial 
evidence through well-controlled, adequate clinical trials that our product candidates are safe and effective for use in a diverse population before we can 
seek marketing approvals for their commercial sale. Success in preclinical studies and early-stage clinical trials does not mean that future larger registration 
clinical trials will be successful. This is because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the 
satisfaction of the FDA and comparable foreign regulatory authorities despite having progressed through nonclinical studies and early-stage clinical trials. 

From  time  to  time,  we  may  publish  or  report  topline,  interim  or  preliminary  data  from  our  clinical  trials.  We  make  assumptions,  estimates, 
calculations, and conclusions as part of our analyses of data, and we may not have received or had the opportunity to evaluate all data fully and carefully. 
As a result, topline, interim or preliminary data from clinical trials that we may conduct may not be indicative of the final results of such trials and are 
subject to the risk that one or more of the clinical outcomes may materially change as subject enrollment continues and more data from the trials become 
available. Topline, interim or preliminary data also remain subject to audit and verification procedures that may result in the final data being materially 
different  from  the  interim  or  preliminary  data.  As  a  result,  topline,  interim  or  preliminary  data  should  be  viewed  with  caution  until  the  final  data  are 
available. 

We are conducting and may in the future choose to conduct clinical trials for current or future product candidates outside of the U.S., and the 

FDA and comparable foreign regulatory authorities may not accept data from such trials. 

We are conducting and may in the future choose to conduct one or more clinical trials outside the U.S. The acceptance of study data from clinical 
trials conducted outside the U.S. or another jurisdiction by the FDA or comparable foreign regulatory authority may be subject to certain conditions or may 
not  be  accepted  at  all.  There  can  be  no  assurance  that  the  FDA  or  any  comparable  foreign  regulatory  authority  will  accept  data  from  trials  conducted 
outside of the U.S. or the applicable jurisdiction. If the FDA or any comparable foreign regulatory authority does not accept such data, it would result in the 
need for additional trials, which could be costly and time-consuming, and which may result in current or future product candidates that we may develop 
being delayed for development or regulatory authorization or not receiving approval for commercialization in the applicable jurisdiction.

We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization 

of LTI-03, LTI-01 or any other product candidates. 

We may experience delays in initiating or completing clinical trials. We also may experience numerous unforeseen events during, or as a result of, 
any  future  clinical  trials  that  could  delay  or  prevent  our  ability  to  receive  marketing  approval  or  commercialize  LTI-03,  LTI-01  or  any  other  product 
candidates, including, but not limited to: 

•

•

regulators or institutional review boards, or IRBs, or ethics committees may not authorize us or our investigators to commence a clinical trial 
or conduct a clinical trial at a prospective trial site; 

the  FDA  or  other  comparable  regulatory  authorities  may  disagree  with  our  clinical  trial  design,  including  with  respect  to  dosing  levels 
administered in our planned clinical trials, which may delay or prevent us from initiating our clinical trials with our originally intended trial 
design; 

41

 
 
•

•

•

•

•

•

•

•

we may experience delays in reaching, or we may fail to reach, agreement on acceptable terms with prospective trial sites and prospective 
contract research organizations, or CROs, which can be subject to extensive negotiation and may vary significantly among different CROs 
and trial sites; 

the  number  of  subjects  required  for  clinical  trials  of  any  product  candidates  may  be  larger  than  we  anticipate  or  patient  recruitment  and 
enrollment may be slow or subjects may drop out of these clinical trials or fail to return for post-treatment follow-up at a higher rate than we 
anticipate; 

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or 
at  all,  or  may  deviate  from  the  clinical  trial  protocol  or  drop  out  of  the  trial,  which  may  require  that  we  add  new  clinical  trial  sites  or 
investigators; 

additional delays and interruptions to our clinical trials could extend the duration of the trials and increase the overall costs to finish the trials 
as our fixed costs are not substantially reduced during delays; 

we  may  elect  to,  or  regulators,  IRBs,  Data  Safety  Monitoring  Boards,  or  DSMBs,  or  ethics  committees  may  require  that  we  or  our 
investigators, suspend or terminate clinical research or trials for various reasons, including noncompliance with regulatory requirements or a 
finding that the participants are being exposed to unacceptable health risks; 

we  may  not  have  the  financial  resources  available  to  begin  and  complete  the  planned  trials,  or  the  cost  of  clinical  trials  of  any  product 
candidates may be greater than we anticipate; 

the  supply  or  quality  of  our  product  candidates  or  other  materials  necessary  to  conduct  clinical  trials  of  our  product  candidates  may  be 
insufficient or inadequate to initiate or complete a given clinical trial; and 

the FDA or other comparable foreign regulatory authorities may require us to submit additional data such as long-term toxicology studies or 
impose other requirements before permitting us to initiate a clinical trial. 

Our product development costs will increase if we experience additional delays in clinical testing or in obtaining marketing approvals. We do not 
know whether any of our clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. If we do not achieve 
our product development goals in the time frames we announce and expect, the approval and commercialization of our product candidates may be delayed 
or prevented entirely. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our 
product  candidates  and  may  allow  our  competitors  to  bring  products  to  market  before  we  do,  potentially  impairing  our  ability  to  successfully 
commercialize our product candidates and harming our business and results of operations. Any delays in our clinical development programs may harm our 
business, financial condition and results of operations significantly. 

Our ongoing and future clinical trials may reveal significant adverse events or unexpected drug-drug interactions not seen in our preclinical 
studies or earlier clinical studies and may result in a safety profile that could delay or prevent regulatory approval or market acceptance of any of our 
product candidates. 

We completed a healthy normal volunteer Phase 1a clinical trial of our clinical product candidate LTI-03. During our LTI-03 Phase 1a clinical trial, 
subjects  experienced  mild  Treatment  Emergent  Adverse  Events,  or  TEAEs,  such  as  dry  cough,  as  well  as  moderate  or  even  severe  TEAEs,  such  as 
wheezing,  chest  tightness,  or  decline  in  the  amount  of  air  a  person  can  force  from  their  lungs  in  one  second.  While  no  subject  experienced  a  Serious 
Adverse Event, or SAE, it is possible that subjects in future clinical studies could develop TEAEs such as the ones experienced in the Phase 1a clinical 
trial, and it is possible that such the number and/or severity of such TEAEs could result in a pause or cessation of the clinical trial. We have also completed 
Phase  1b  and  Phase  2a  clinical  trials  of  our  clinical  product  candidate  LTI-01  in  LPE  patients.  In  the  Phase  2a  trial,  four  subjects  experienced  TEAEs, 
including  1  mild,  2  moderate,  and  1  severe  TEAE.  There  were  no  SAEs  reported.  The  product  candidate  was  concluded  to  be  generally  well-tolerated 
across all doses in trial participants. 

If significant adverse events or other side effects are observed in any of our ongoing or future clinical trials, whether or not related to our product 
candidates, we may have difficulty recruiting patients to our clinical trials, patients may drop out of our trials, or we may be required to abandon the trials 
or our development efforts altogether 

42

 
 
or may result in safety profile that could delay or prevent regulatory approval or market acceptance of any of our product candidates. 

Clinical development involves a lengthy, complex and expensive process, with an uncertain outcome. 

To obtain the requisite regulatory approvals to commercialize any product candidates, we must demonstrate through extensive preclinical studies 
and clinical trials that our product candidates are safe and effective in humans. Clinical testing is expensive and can take many years to complete, and its 
outcome is inherently uncertain. In particular, the general approach for FDA approval of a new drug is dispositive data from two well-controlled, Phase 3 
clinical trials of the relevant drug in the relevant patient population. Phase 3 clinical trials typically involve many patients, have significant costs and can 
take years to complete. A product candidate can fail at any stage of testing, even after observing promising signals of activity in earlier preclinical studies 
or  clinical  trials.  The  results  of  preclinical  studies  and  early  clinical  trials  of  our  product  candidates  may  not  be  predictive  of  the  results  of  later-stage 
clinical trials. In addition, initial success in clinical trials may not be indicative of results obtained when such trials are completed. There is typically an 
extremely high rate of attrition of candidate therapies from failure of these candidates proceeding through clinical trials. Product candidates in later stages 
of clinical trials may fail to show the desired safety and efficacy profile despite having progressed through preclinical studies and previous clinical trials. A 
number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable 
safety issues, notwithstanding promising results in earlier trials. Most product candidates that commence clinical trials are never approved as new drugs and 
there can be no assurance that any of our future clinical trials will ultimately be successful or support further clinical development of LTI-03 and LTI-01 or 
any of our other product candidates. Product candidates that appear promising in the early phases of development may fail to reach the market for several 
reasons, including, but not limited to: 

•

•

•

•

•

•

clinical trials or preclinical studies may show the product candidates to be less effective than expected (e.g., a clinical trial could fail to meet 
its primary endpoint(s)) or to have unacceptable side effects or toxicities; 

failure to establish clinical endpoints that applicable regulatory authorities would consider clinically meaningful; 

failure to receive the necessary regulatory approvals; 

failure of contract manufacturers to comply with regulatory requirements; 

manufacturing costs, formulation issues, pricing or reimbursement issues, or other factors that make a product candidate uneconomical; and 

the proprietary rights of others and their competing products and technologies that may prevent one of our product candidates from being 
commercialized. 

In addition, differences in trial design between early-stage clinical trials and later-stage clinical trials make it difficult to extrapolate the results of 
earlier clinical trials to later clinical trials. Moreover, clinical data are often susceptible to varying interpretations and analyses, and many candidates that 
have performed satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of their products. Some of our future trials may be open 
label studies, where both the patient and investigator know whether patient is receiving the investigational product candidate or either an existing approved 
drug or placebo. Most typically, open label clinical trials test only the investigational product candidates and sometimes do so at different dose levels. Open 
label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open label clinical trials are aware when they 
are receiving treatment. In addition, open label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological 
outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably 
given this knowledge. Therefore, it is possible that positive results observed in open label trials will not be replicated in later placebo-controlled trials.

In  addition,  the  standards  that  the  FDA  and  comparable  foreign  regulatory  authorities  use  when  regulating  us  require  judgment  and  can  change, 
which  makes  it  difficult  to  predict  with  certainty  how  they  will  be  applied.  Any  analysis  we  perform  of  data  from  preclinical  and  clinical  activities  is 
subject  to  confirmation  and  interpretation  by  regulatory  authorities,  which  could  delay,  limit  or  prevent  regulatory  approval.  We  may  also  encounter 
unexpected 

43

 
 
delays or increased costs due to new government regulations. Examples of such regulations include future legislation or administrative action, or changes in 
FDA policy during the period of product development and FDA regulatory review. It is impossible to predict whether legislative changes will be enacted, 
or whether the FDA or foreign regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be. The FDA also 
requires a panel of experts, referred to as an Advisory Committee, to deliberate on the adequacy of the safety and efficacy data to support product candidate 
approval. The opinion of the Advisory Committee, although not binding, may have a significant impact on our ability to obtain approval of any product 
candidates that we develop. 

If  we  seek  to  conduct  clinical  trials  in  foreign  countries  or  pursue  marketing  approvals  in  foreign  jurisdictions,  we  must  comply  with  numerous 
foreign regulatory requirements governing, among other things, the ethical conduct of clinical trials, manufacturing and marketing authorization, pricing 
and  third-party  reimbursement.  The  foreign  regulatory  approval  process  varies  among  countries  and  may  include  all  of  the  risks  associated  with  FDA 
approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain 
approval may differ from that required to obtain FDA approval. Approval by the FDA does not ensure approval by regulatory authorities outside the U.S. 
and vice versa. 

Successful  completion  of  clinical  trials  is  a  prerequisite  to  submitting  a  marketing  application  to  the  FDA  and  similar  marketing  applications  to 
comparable foreign regulatory authorities, for each product candidate and, consequently, the ultimate approval and commercial marketing of any product 
candidates.  We  may  experience  negative  or  inconclusive  results,  which  may  result  in  our  deciding,  or  our  being  required  by  regulators,  to  conduct 
additional  clinical  studies  or  trials  or  abandon  some  or  all  of  our  product  development  programs,  which  could  have  a  material  adverse  effect  on  our 
business. 

Studies  involving  human  tissue  samples  may  also  be  subject  to  institutional  and  government  human  subject  privacy  policies  that  may  vary  by 
territory. We or our partners which use human tissue samples or conduct tissue and/or animal studies on our behalf, may be found to be in violation of one 
or more of these regulations or policies and may be subject to closure, censure or other penalties. In some cases, these penalties could materially impact the 
performance, availability, or validity of studies conducted by us or on our behalf. Even in the absence of violations resulting in penalties, regulatory and 
other authorities may refuse to authorize the conduct or to accept the results of studies for regulatory or ethical reasons. 

If  we  encounter  difficulties  enrolling  and  retaining  patients  in  our  clinical  trials,  our  clinical  development  activities  could  be  delayed  or 

otherwise adversely affected. 

We  may  experience  difficulties  in  patient  enrollment  in  our  clinical  trials  for  a  variety  of  reasons.  The  timely  completion  of  clinical  trials  in 
accordance  with  their  protocols  depends,  among  other  things,  on  our  ability  to  enroll  a  sufficient  number  of  patients  who  remain  in  the  trial  until  its 
conclusion. The enrollment of patients depends on many factors, including, but not limited to: 

•

•

•

•

•

•

•

•

the patient eligibility and exclusion criteria defined in the protocol; 

the size of the patient population required for analysis of the trial’s primary endpoints and the process for identifying patients; 

the willingness or availability of patients to participate in our trials; 

the proximity of patients to trial sites; 

the design of the trial; 

our ability to recruit clinical trial investigators with the appropriate competencies and experience; 

clinicians’  and  patients’  perceptions  as  to  the  potential  advantages  and  risks  of  the  product  candidate  being  studied  in  relation  to  other 
available therapies, including any new products that may be approved for the indications we are investigating; 

the availability of competing commercially available therapies and other competing product candidates’ clinical trials; 

44

 
 
•

•

our ability to obtain and maintain patient informed consents; and 

the risk that patients enrolled in clinical trials will drop out of the trials or are discontinued from trials at the recommendation of the principal 
investigator before completion. 

For example, we are developing LTI-03 for the treatment of IPF, which is an orphan indication. In the U.S., IPF is estimated to affect approximately 
100,000 people. As a result, we may encounter difficulties enrolling subjects in our clinical trials of LTI-03 due, in part, to the small size of this patient 
population.  In  addition,  our  clinical  trials  could  compete  with  other  clinical  trials  for  product  candidates  that  are  in  the  same  therapeutic  areas  as  our 
product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll 
in our trials may instead opt to enroll in a trial being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, it 
is  possible  that  we  would  conduct  some  of  our  clinical  trials  at  the  same  clinical  trial  sites  that  a  competitor  uses,  which  would  reduce  the  number  of 
patients who are available for our clinical trials in such clinical trial site. Certain of our planned clinical trials may also involve invasive procedures such as 
bronchoscopy and broncho-alveolar lavage procedure, which may lead some patients to drop out of trials to avoid these follow-up procedures. In addition, 
patients participating in our clinical trials may drop out before completion of the trial or experience adverse medical events unrelated to our products. 

If  approved,  our  product  candidates  that  are  regulated  as  biologics  may  face  competition  from  biosimilars  approved  through  an  abbreviated 

regulatory pathway. 

The Biologics Price Competition and Innovation Act of 2009, or BPCIA, was enacted as part of the Patient Protection and Affordable Care Act, or 
the  ACA,  to  establish  an  abbreviated  pathway  for  the  biosimilar  and  interchangeable  biological  products.  The  regulatory  pathway  establishes  legal 
authority  for  the  FDA  to  review  and  approve  biosimilar  biologics,  including  the  possible  designation  of  a  biosimilar  as  “interchangeable”  based  on  its
similarity to an approved biologic. Under the BPCIA, a reference biological product is granted 12 years of data exclusivity from the time of first licensure 
of the product, and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four 
years after the date of first licensure of the reference product. In addition, the approval of a biosimilar product may not be made effective by the FDA until 
12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still develop and 
receive approval of a competing biologic, so long as their biologics license application, or BLA, does not rely on the reference product, sponsor’s data or 
submit the application as a biosimilar application. The law is complex and is still being interpreted and implemented by the FDA. As a result, the law’s 
ultimate impact, implementation, and meaning are subject to uncertainty, and any new policies or processes adopted by the FDA could have a material 
adverse effect on the future commercial prospects for our biological products.

 We believe that any of the product candidates we develop that are approved in the U.S. as a biological product under a BLA may qualify for the 12-
year period of exclusivity. However, there is a risk that the FDA may not grant exclusivity, this exclusivity could be shortened due to congressional action 
or otherwise undermined by a competitor, or that the FDA will not consider the subject product candidates to be reference products for competing products, 
potentially creating the opportunity for biosimilar competition sooner than anticipated. Moreover, the extent to which a biosimilar, once approved, will be 
substituted for any one of the reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and 
will depend on a number of marketplace and regulatory factors that are still developing. The approval of a biosimilar of our product candidates could have 
a material adverse impact on our business due to increased competition and pricing pressure. 

Although we have received U.S. Orphan Drug Designation for LTI-03 for IPF and U.S. and European Union, or EU, Orphan Drug Designation 
for LTI-01 for pleural empyema, we may be unable to obtain and maintain Orphan Drug Designation for our other product candidates and, even if we 
obtain  such  designation,  we  may  not  be  able  to  realize  the  benefits  of  such  designation,  including  potential  marketing  exclusivity  of  our  product 
candidates, if approved.

Regulatory  authorities  in  some  jurisdictions,  including  the  U.S.  and  other  major  markets,  may  designate  drugs  intended  to  treat  conditions  or 
diseases affecting relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, the FDA may designate a product candidate as 
an  orphan  drug  if  it  is  intended  to  treat  a  rare  disease  or  condition,  which  is  generally  defined  as  having  a  patient  population  of  fewer  than  200,000 
individuals 

45

 
 
in the U.S. or a patient population greater than 200,000 in the U.S. where there is no reasonable expectation that the cost of developing the drug will be 
recovered from sales in the U.S. 

Regulation (EC) No. 141/2000 specifies the requirements for designation as an orphan drug at the EU level. The medicinal product must be intended 
(i)  for  the  treatment  of  a  life-threatening  or  chronically  debilitating  disease  affecting  no  more  than  five  in  10,000  individuals  in  the  EU,  or  (ii)  for  the 
treatment  of  a  correspondingly  serious  condition  described  in  the  Regulation,  and  in  both  cases,  without  additional  incentives,  the  marketing  of  the 
medicinal product must be unlikely to generate sufficient profit to justify the necessary investment. If one of the two alternatives applies, it is assumed that 
there is no other satisfactory treatment method or, if such a method exists, that the new product has a significant therapeutic benefit compared to it. 

Although we have received U.S. Orphan Drug Designation for LTI-03 for IPF and U.S. and EU Orphan Drug Designation for LTI-01 for pleural 
empyema,  we  have  not  received  U.S.  Orphan  Drug  Designation  for  LTI-01  for  LPE,  which  is  the  first  indication  that  we  are  pursuing  for  LTI-01. 
Furthermore,  the  designation  of  any  of  our  product  candidates  as  an  orphan  drug  does  not  mean  that  any  regulatory  agency  will  accelerate  regulatory 
review of, or ultimately approve, that product candidate, nor does it limit the ability of any regulatory agency to grant Orphan Drug Designation to product 
candidates of other companies that treat the same indications as our product candidates. 

Generally, if a product candidate with an Orphan Drug Designation in the U.S. receives the first marketing approval for the indication for which it 
has such designation, the product is entitled to a period of marketing exclusivity, which precludes FDA from approving another marketing application for a 
product  that  constitutes  the  same  drug  treating  the  same  indication  for  that  marketing  exclusivity  period,  except  in  limited  circumstances.  Similar 
exclusivity rights apply under EU law if a product candidate with Orphan Drug Designation is authorized in the EU. Designation does not mean approval. 
Even  if  we  obtain  marketing  authorization,  the  FDA  may  choose  not  to  grant  exclusivity.  In  the  EU,  market  exclusivity  only  applies  if  the  criteria  for 
orphan drug designation still subsist at the time when the marketing authorization is granted. The applicable period is seven years in the U.S. and ten years 
in the EU. Under EU law, the period of exclusivity may be reduced to six years if it is established, at the end of the fifth year, that the criteria for orphan 
drug  designation  are  no  longer  met.  In  the  U.S.,  orphan  drug  exclusivity  may  be  revoked  if  the  FDA  determines  that  the  request  for  designation  was 
materially  defective  or  if  the  manufacturer  is  unable  to  assure  sufficient  quantity  of  the  product  to  meet  the  needs  of  patients  with  the  rare  disease  or 
condition. 

Under EU law, the protection of an orphan medicinal product does not only apply to medicinal products with the same active substance, but extends 
to all “similar medicinal products”. This is determined by the molecular structure, the mechanism of action and the approved therapeutic indication. Once 
an orphan medicinal product has been authorized, the European Commission, the EMA and the national regulatory authorities may not, for a period of ten 
years  from  the  date  of  authorization,  in  respect  of  such  similar  medicinal  products  for  the  same  therapeutic  indication:  accept  another  application  for 
authorization,  grant  a  corresponding  authorization,  or  grant  an  application  to  extend  an  existing  authorization.  Thus,  not  only  market  exclusivity  is 
conferred, but also additional protection by prohibiting any application and/or granting of authorization for a similar medicinal product during this 10-year 
period. 

Yet,  even  if  we  obtain  orphan  drug  exclusivity  for  a  product  candidate,  that  exclusivity  may  not  effectively  protect  the  product  candidate  from 
competition because different drugs can be approved for the same condition or the FDA or the European Commission can approve a similar drug for a 
different indication. Even after an orphan drug is approved, the FDA may subsequently approve another drug for the same condition if the FDA concludes 
that the latter drug is not the same drug or is clinically superior in that it is shown to be safer, more effective, or makes a major contribution to patient care. 
In the EU, another similar product in the same indication may be approved if the holder of the orphan designation is unable to supply sufficient quantities 
of the product or if the second applicant can establish clinical superiority of its product. 

On April 26, 2023, the European Commission presented a draft for a comprehensive reform of the pharmaceutical legislation. The so-called “EU 
pharmaceutical package” provides, among others, for a new regulation to replace Regulation (EC) No. 141/2000 on orphan medicinal products. The draft 
regulation introduces the possibility of establishing new designation criteria by the EMA and the restriction of designation as an orphan drug to generally 
seven years. The draft regulation also provides for more flexible rules on the duration of market exclusivity, including: ten years of market exclusivity for 
orphan drugs in the case of “high unmet medical need”, five years for orphan drugs, approved by a bibliographic marketing authorization and nine years in 
all other cases with the possibility of extension 

46

 
 
in the case of market access in all Member States (another year) or development of new therapeutic indications for an already authorized orphan medicinal 
product (up to two years). Market exclusivity can thus add up to a maximum of thirteen years, whereas today it is still capped at ten years. It should be 
noted that the market exclusivity right of the orphan medicinal product does not prevent the submission, validation and assessment of an application for 
marketing authorization of a similar medicinal product, including generics and biosimilars, if the remaining duration of the market exclusivity right is less 
than two years. The EU pharmaceutical package is still at an early stage of the legislative process. It may still undergo substantial changes and is expected 
to turn into binding law in several years’ time. 

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay. 

As  product  candidates  progress  through  preclinical  to  later-stage  clinical  trials  to  marketing  approval  and  commercialization,  it  is  common  that 
various  aspects  of  the  development  program,  such  as  manufacturing  methods  and  formulation,  are  altered  along  the  way  in  an  effort  to  optimize  yield, 
manufacturing batch size, minimize costs and achieve consistent quality and results. Such changes carry the risk that they will not achieve these intended 
objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future 
clinical  trials  conducted  with  the  altered  materials.  This  could  delay  completion  of  clinical  trials,  require  the  conduct  of  bridging  clinical  trials  or  the 
repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commercialize 
our product candidates and generate revenue. 

In addition, there are risks associated with large scale manufacturing for clinical trials or commercial scale including, among others, cost overruns, 
potential  problems  with  process  scale-up,  process  reproducibility,  stability  issues,  compliance  with  good  manufacturing  practices,  lot  consistency  and 
timely availability of raw materials. Even if we obtain marketing approval for any of our product candidates, there is no assurance that our manufacturers 
will be able to manufacture the approved product to specifications acceptable to the FDA or other comparable foreign regulatory authorities, to produce it 
in sufficient quantities to meet the requirements for the potential commercial launch of the product or to meet potential future demand. If our manufacturers 
are unable to produce sufficient quantities for clinical trials or for commercialization, our development and commercialization efforts would be impaired, 
which would have an adverse effect on our business, financial condition, results of operations and growth prospects. 

Due  to  our  limited  resources  and  access  to  capital,  we  must  make  decisions  on  the  allocation  of  resources  to  certain  programs  and  product 

candidates; these decisions may prove to be wrong and may adversely affect our business. 

We  have  limited  financial  and  human  resources  and  intend  to  initially  focus  on  research  programs  and  product  candidates  for  a  limited  set  of 
indications. As a result, we may forgo or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater 
commercial potential or a greater likelihood of success. This approach may cause us to commit significant resources to prepare for and conduct later-stage 
trials for one or more product candidates that subsequently fail earlier-stage clinical testing. Therefore, our resource allocation decisions may cause us to 
fail to capitalize on viable commercial products or profitable market opportunities, or expend resources on product candidates that are not viable. 

There can be no assurance that we will ever be able to identify additional therapeutic opportunities for our product candidates or to develop suitable 
potential product candidates through internal research programs, which could materially adversely affect our future growth and prospects. We may focus
our efforts and resources on potential product candidates or other potential programs that ultimately prove to be unsuccessful. 

Mergers  and  acquisitions  in  the  biopharmaceutical  and  biotechnology  industries  may  result  in  even  more  resources  being  concentrated  among  a 
smaller  number  of  our  competitors.  Smaller  or  early  stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative 
arrangements  with  large  and  established  companies.  These  competitors  also  compete  with  us  in  recruiting  and  retaining  qualified  scientific  and 
management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, 
or necessary for, our programs. Our commercial opportunity could be reduced or 

47

 
 
eliminated if our competitors develop and commercialize products that are safer, more effective, more convenient, or less expensive than any products that 
we may develop. Furthermore, products currently approved for other indications could be discovered to be effective treatments of IPF and LPE as well, 
which  could  give  such  products  significant  regulatory  and  market  timing  advantages  over  LTI-03  and  LTI-01  or  other  product  candidates  that  we  may 
identify.  Currently,  off-label  use  of  fibrinolytics  is  utilized  in  many  hospitals  for  the  treatment  of  LPE.  Our  competitors  also  may  obtain  FDA  or  other 
regulatory  approval  for  their  products  more  rapidly  than  we  may  obtain  approval  for  ours,  which  could  result  in  our  competitors  establishing  a  strong 
market position before we are able to enter the market. If competitors obtain patent protection or market exclusivity for their products before any of our 
products are approved, they could significantly delay the approval, and even review (in some cases), of our marketing application. Additionally, products or 
technologies  developed  by  our  competitors  may  render  our  potential  product  candidates  uneconomical  or  obsolete  and  we  may  not  be  successful  in 
marketing any product candidates we may develop against competitors. The availability of competitive products could limit the demand, and the price we 
are able to charge, for any products that we may develop and commercialize. 

We may not be successful in our efforts to identify or discover additional product candidates in the future. 

Our  research  programs  may  initially  show  promise  in  identifying  potential  product  candidates,  yet  fail  to  yield  product  candidates  for  clinical 

development for a number of reasons, including, but not limited to: 

•

•

our inability to design or obtain such product candidates with the pharmacological properties that we desire or attractive pharmacokinetics; or 

potential product candidates may, on further study, be shown to have harmful side effects or other characteristics that indicate that they are 
unlikely to be medicines that will receive marketing approval and achieve market acceptance. 

We have Cav1-related peptides in preclinical development for potentially a broad number of fibrosis indications. Many of these fibrosis indications 
may require a systemically delivered formulation to effectively treat these indications. We have not finalized a systemic formulation of a proprietary Cav1-
related peptide and are currently developing potential systemic formulations. In the event we are unable to successfully complete a suitable formulation for 
therapeutic delivery, we may not be able to develop product candidates to address additional fibrosis indications. Even if we are able to develop a systemic 
formulation, it is possible that this systemic delivered product candidate will fail to show sufficient efficacy or safety in later stages of testing to proceed 
with development. 

We face substantial competition, which may result in others discovering, developing or commercializing products before or more successfully 

than us. 

The  development  and  commercialization  of  new  drug  products  is  highly  competitive.  We  may  face  competition  with  respect  to  any  product 
candidates that we seek to develop or commercialize in the future from major biopharmaceutical companies, specialty biopharmaceutical companies and 
biotechnology companies worldwide. Potential competitors also include academic institutions, government agencies, and other public and private research 
organizations  that  conduct  research,  seek  patent  protection  and  establish  collaborative  arrangements  for  research,  development,  manufacturing,  and 
commercialization. 

There are a number of large biopharmaceutical and biotechnology companies that are currently pursuing the commercialization or development of 
products  for  the  treatment  of  fibrosis.  Companies  that  we  are  aware  of  that  are  targeting  the  treatment  of  various  fibrosis  indications  include  large 
companies  with  significant  financial  resources  such  as,  but  not  limited  to:  AbbVie  Inc.,  Boehringer  Ingelheim  GmbH,  Bristol  Myers  Squibb  Company, 
Gilead Sciences, Inc., Roche Holding AG, Novartis AG, and Pliant Therapeutics, Inc. Many of our current or potential competitors, either alone or with 
their  strategic  partners,  have  significantly  greater  financial  resources  and  expertise  in  research  and  development,  manufacturing,  preclinical  testing, 
conducting clinical trials, obtaining regulatory approvals, and marketing approved products than we do. There are currently no approved therapeutics for 
the treatment of LPE. Roche Holding AG manufactures tissue plasminogen activator, or tPA, and recombinant deoxyribonuclease, or DNase, which are 
used off-label to treat LPE patients. We are not aware of any other pharmaceutical or biotechnology companies developing drug therapies for the treatment 
of LPE.

If  product  liability  lawsuits  are  brought  against  us,  we  may  incur  substantial  financial  or  other  liabilities  and  may  be  required  to  limit 

commercialization of our product candidates. 

We face an inherent risk of product liability as a result of testing LTI-03, LTI-01 and any of our other product candidates in clinical trials, and will 
face an even greater risk if we commercialize any products. For example, we may be sued if any of our product candidates cause or are perceived to cause 
injury  or  are  found  to  be  otherwise  unsuitable  during  clinical  trials,  manufacturing,  marketing  or  sale.  Any  such  product  liability  claims  may  include 
allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of 
warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, 
we may incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense would require significant 
financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in: 

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

inability to bring a product candidate to the market; 

decreased demand for our products; 

injury to our reputation; 

withdrawal of clinical trial participants and inability to continue clinical trials; 

initiation of investigations by regulators; 

fines, injunctions or criminal penalties; 

costs to defend the related litigation; 

diversion of management’s time and our resources; 

substantial monetary awards to trial participants; 

product recalls, withdrawals or labeling, marketing or promotional restrictions; 

loss of revenue; 

exhaustion of any available insurance and our capital resources; 

adverse effects to our results of operations and business; 

the inability to commercialize any product candidate, if approved; and 

decline in our share price. 

Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or 
inhibit the commercialization of products we develop, alone or with collaboration partners. We will need to obtain additional insurance for clinical trials as 
LTI-03  and  LTI-01  continue  clinical  development  and  as  additional  product  candidates  enter  the  clinic.  However,  we  may  be  unable  to  obtain,  or  may 
obtain on unfavorable terms, clinical trial insurance in amounts adequate to cover any liabilities from any of our clinical trials. Our insurance policies may 
also have various exclusions, and we may be subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded 
by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to 
obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, 
such indemnification may not be available or adequate should any claim arise. 

Risks Related to Marketing Approval 

We have never obtained marketing approval for a product candidate and we may be unable to obtain, or may be delayed in obtaining, marketing 

approval for any product candidate. 

We have never obtained marketing approval for a product candidate. It is possible that the FDA may refuse to accept for substantive review any new 

drug applications, or NDAs, or biologics license applications, or BLAs, that 

49

 
 
we  submit  for  our  product  candidates  or  may  conclude  after  review  of  our  data  that  our  application  is  insufficient  to  obtain  marketing  approval  of  our 
product  candidates.  If  the  FDA  does  not  accept  or  approve  our  NDAs  or  BLAs  for  our  product  candidates,  it  may  require  that  we  conduct  additional 
clinical, nonclinical or manufacturing validation studies and submit that data before it will reconsider our applications. Depending on the extent of these or 
any other FDA-required studies, approval of any NDA or BLA, or application that we submit may be delayed by several years, or may require us to expend 
more resources than we have available. It is also possible that additional studies, if performed and completed, may not be considered sufficient by the FDA 
to approve our NDAs or BLAs. 

Any delay in obtaining, or an inability to obtain, marketing approvals would prevent us from commercializing our product candidates, generating 
revenues and achieving and sustaining profitability. If any of these outcomes occur, we may be forced to abandon our development efforts for our product 
candidates, which could significantly harm our business. 

We currently have no marketing and sales organization and have no experience as a company in commercializing products, and we may have to 
invest significant resources to develop these capabilities. If we are unable to establish marketing and sales capabilities or enter into agreements with 
third parties to market and sell our products, we may not be able to generate product revenue. 

We have no internal sales, marketing or distribution capabilities, nor have we commercialized a product. If any of our product candidates ultimately 
receives regulatory approval, we expect to establish a marketing and sales organization with technical expertise and supporting distribution capabilities to 
commercialize  each  such  product  in  major  markets,  which  will  be  expensive  and  time  consuming.  We  have  no  prior  experience  as  a  company  in  the 
marketing,  sale  and  distribution  of  pharmaceutical  products  and  there  are  significant  risks  involved  in  building  and  managing  a  sales  organization, 
including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing 
personnel  and  effectively  manage  a  geographically  dispersed  sales  and  marketing  team.  Any  failure  or  delay  in  the  development  of  our  internal  sales, 
marketing  and  distribution  capabilities  would  adversely  impact  the  commercialization  of  these  products.  We  may  also  choose  to  collaborate  with  third 
parties that have direct sales forces and established distribution systems, either to augment our own sales force and distribution systems or in lieu of our 
own sales force and distribution systems. Notwithstanding our current license and collaboration agreement with Taiho, we may not be able to enter into 
future  collaborations  or  hire  consultants  or  external  service  providers  to  assist  us  in  sales,  marketing  and  distribution  functions  on  acceptable  financial 
terms, or at all, which may result in being unable to successfully commercialize our products. In addition, our product revenues and our profitability, if any, 
may be lower if we rely on third parties for these functions than if we were to market, sell and distribute any products that we develop ourselves. We likely 
will have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our products 
effectively. If we are not successful in commercializing our product candidates, either on our own or through arrangements with one or more third parties, 
we may not be able to generate any future product revenue and we would incur significant additional losses. 

Even  if  a  product  candidate  we  develop  receives  marketing  approval,  it  may  fail  to  achieve  the  degree  of  market  acceptance  by  physicians, 

patients, third-party payors and others in the medical community necessary for commercial success. 

Even if LTI-03, LTI-01 or any other product candidate we develop receives marketing approval, it may nonetheless fail to gain sufficient market 
acceptance by physicians, patients, third-party payors, such as Medicare and Medicaid programs and managed care organizations, and others in the medical 
community. Our belief that LTI-01 compares well on dosing schedule, surgical referrals and side effect profile compared to off-label IPFT treatment, such 
as tPA with DNase, to treat LPE patients is based upon limited data from our completed clinical trials. In addition, the availability of coverage by third-
party payors may be affected by existing and future health care reform measures designed to reduce the cost of health care. If the product candidates we 
develop do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable. 

The degree of market acceptance of any product candidate, if approved for commercial sale, will depend on a number of factors, including, but not 

limited to: 

•

efficacy and potential advantages compared to alternative treatments; 

50

 
 
•

•

•

•

•

•

•

the ability to offer our products, if approved, for sale at competitive prices; 

convenience and ease of administration compared to alternative treatments; 

the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; 

the recommendations with respect to our product candidates in guidelines published by various scientific organizations applicable to us and 
our product candidates; 

the strength of marketing and distribution support; 

the ability to obtain sufficient third-party coverage, and adequate reimbursement; and 

the prevalence and severity of any side effects. 

If government and other third-party payors do not provide coverage and adequate reimbursement levels for any products we commercialize, market 

acceptance and commercial success would be reduced. 

In  addition,  even  if  we  obtain  approval,  the  FDA  or  a  comparable  foreign  regulatory  authority  might  add  specific  warnings  to  the  product  label, 
making promotion more difficult. In the U.S., for example, a product with a “Boxed Warning” which is a call-out warning for the possibility of a serious, 
life-threatening risk, carries promotional restrictions. In addition, due to the nature of the serious risk potentially associated with the drug, necessitating the 
Boxed Warning, public acceptance of the product may be challenging. 

Even  if  we  complete  the  necessary  preclinical  studies  and  clinical  trials,  the  marketing  approval  process  is  expensive,  time-consuming  and 
uncertain and may prevent us, or any future collaborators, from obtaining approvals for the commercialization of LTI-03, LTI-01 or any other product 
candidate  that  we  may  develop.  As  a  result,  we  cannot  predict  when  or  if,  and  in  which  territories  or  for  which  indications,  we,  or  any  future 
collaborators, will obtain marketing approval to commercialize LTI-03, LTI-01 or any other product candidate that we may develop. 

The research, testing, manufacturing, labeling, approval, selling, marketing, promotion and distribution of drugs are subject to extensive regulation 
by  the  FDA  and  comparable  foreign  regulatory  authorities,  whose  laws  and  regulations  may  differ  from  country  to  country.  We,  and  any  future 
collaborators, are not permitted to market our product candidates in the U.S. or in other countries until we or they receive approval of an NDA or BLA 
from the FDA or marketing approval from comparable foreign regulatory authorities. LTI-03 and LTI-01 are in early stages of development and are subject 
to the risks of failure inherent in drug development. We have not submitted an application for or received marketing approval for LTI-03, LTI-01 or any of 
our future product candidates in the U.S. or in any other jurisdiction. We have limited experience in conducting and managing the clinical trials necessary 
to obtain marketing approvals, including FDA approval of an NDA or BLA. 

The process of obtaining marketing approvals, both in the U.S. and abroad, is a lengthy, expensive and uncertain process. It may take many years, if 
approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates 
involved.  Securing  marketing  approval  requires  the  submission  of  extensive  preclinical  and  clinical  data  and  supporting  information  to  regulatory 
authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the submission 
of  information  about  the  product  manufacturing  process  to,  and  inspection  of  manufacturing  facilities  by,  the  regulatory  authorities.  The  FDA  or  other 
regulatory authorities have substantial discretion and may determine that our product candidates are not safe and effective, only moderately effective or 
have  undesirable  or  unintended  side  effects,  toxicities  or  other  characteristics  that  preclude  our  obtaining  marketing  approval  or  prevent  or  limit 
commercial use. Any marketing approval we ultimately obtain may be limited or subject to restrictions, such as the aforementioned Boxed Warning in the 
product label, or post-approval commitments that render the approved product not commercially viable. 

Our product candidates could fail to receive marketing approval for many reasons, including the following: 

51

 
 
•

•

•

•

•

•

•

•

•

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials; 

we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that a product candidate is safe
and effective for its proposed indication; 

the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities 
for approval; 

we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks; 

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials; 

the  data  collected  from  clinical  trials  of  our  product  candidates  may  not  be  sufficient  to  support  the  submission  of  an  NDA  or  other 
submission or to obtain marketing approval in the U.S. or elsewhere; 

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  the  manufacturing  processes  or  facilities  of  third-party 
manufacturers with which we contract for clinical and commercial supplies due to quality manufacturing concerns; 

the  FDA  or  comparable  foreign  regulatory  authorities  may  fail  to  approve  any  companion  diagnostics  that  may  be  required  in  connection 
with approval of our therapeutic product candidates; and 

the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change in a manner rendering 
our clinical data insufficient for approval. 

This lengthy approval process as well as the unpredictability of clinical trial results may result in our failing to obtain marketing approval to market 

our product candidates, which would significantly harm our business, results of operations and prospects. 

In  addition,  changes  in  marketing  approval  policies  during  the  development  period,  changes  in  or  the  enactment  or  promulgation  of  additional 
statutes, regulations or guidance or changes in regulatory review for each submitted drug application may cause delays in the approval or rejection of an 
application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data 
are insufficient for approval and require additional preclinical studies, clinical trials or other studies and testing. In addition, varying interpretations of the 
data obtained from preclinical studies and clinical trials could delay, limit or prevent marketing approval of a product candidate. Any marketing approval 
we, or any collaborators we may have in the future, ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the 
approved drug not commercially viable. 

Any delay in obtaining or failure to obtain required approvals could materially adversely affect our ability or that of any collaborators we may have 
to generate revenue from the particular product candidate, which likely would result in significant harm to our financial position and adversely impact our 
stock price. 

Failure to obtain marketing approval in foreign jurisdictions would prevent our product candidates from being marketed abroad. Any approval 

we are granted for LTI-03 or LTI-01 in the U.S. would not assure approval of our product candidates in foreign jurisdictions. 

In order to market and sell our products in the EU and many other foreign jurisdictions, we or our potential third-party collaborators must obtain 
separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can 
involve  additional  testing.  The  time  required  to  obtain  approval  may  differ  substantially  from  that  required  to  obtain  FDA  approval.  The  regulatory 
approval process outside of the U.S. generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside of 
the U.S., it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We or our potential 
third-party collaborators may not obtain approvals from regulatory authorities outside of the U.S. on a timely basis, if at all. Approval by the FDA does not 
ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside of the 

52

 
 
U.S.  does  not  ensure  approval  by  regulatory  authorities  in  other  countries  or  jurisdictions  or  by  the  FDA.  However,  a  failure  or  delay  in  obtaining 
regulatory  approval  in  one  country  may  have  a  negative  effect  on  the  regulatory  process  in  other  countries.  We  may  not  be  able  to  file  for  marketing 
approvals and may not receive necessary approvals to commercialize our products candidates in any market. 

The  above-mentioned  EU  pharmaceutical  package  does  not  intend  to  change  the  existing  procedures  currently  in  place  at  EU  level:  Medicinal 
products  are  still  to  be  approved  in  the  decentralized  procedure,  mutual  recognition  procedure,  or  centralized  procedure.  However,  the  duration  of 
authorization procedures is generally to be reduced. The decisive factor for the reduction of the duration of the procedure under the decentralized procedure 
and the mutual recognition procedure is the reduction of the period of cooperation of the EU member states. In regards of the centralized procedure, the 
shortening of the overall duration results from the accumulation of several small reductions in time. 

Additionally,  we  could  face  heightened  risks  with  respect  to  seeking  marketing  approval  in  the  United  Kingdom,  or  the  UK,  as  a  result  of  the 
withdrawal of the UK from the EU, commonly referred to as Brexit. Brexit may have a material impact upon the regulatory regime with respect to the 
development, manufacture, importation, approval and commercialization of product candidates in the UK. 

The UK is no longer part of the European Single Market and EU Customs Union. Though a significant proportion of the regulatory framework for 
pharmaceutical  products  in  the  UK  covering  the  quality,  safety,  and  efficacy  of  pharmaceutical  products,  clinical  trials,  marketing  authorization, 
commercial sales, and distribution of pharmaceutical products is derived from EU Directives and Regulations, there are some significant changes made to 
the regulatory framework to address the UK’s departure from the EU. 

The  Medicines  and  Healthcare  products  Regulatory  Agency,  or  the  MHRA,  is  the  national  regulator  responsible  for  supervising  medicines  and 
medical devices in the UK, comprising England, Scotland, Wales, and Northern Ireland. England, Scotland, and Wales form Great Britain which follows 
domestic law, whereas Northern Ireland currently continues to be subject to EU rules under the Northern Ireland Protocol. The main domestic legislation 
regulating medicines in the UK is the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), or the HMR. The HMR has incorporated into 
domestic law some of the body of EU law instruments governing medicinal products that pre-existed prior to the UK’s withdrawal from the EU and has 
been amended to take into account the country’s departure from the EU. Other domestic law implements the other corpus of EU medicines law that existed 
prior to the UK’s departure from the EU. 

Following  Brexit,  national  marketing  authorizations  in  the  UK  can  be  obtained  to  cover  the  whole  of  the  UK  (UKMA(UK)),  Great  Britain 
(UKMA(GB))  or  Northern  Ireland  (UKMA(NI)),  through  the  different  available  marketing  authorization  routes.  Northern  Ireland  also  continues  to 
participate  in  the  EU  marketing  authorization  routes.  In  this  case,  the  UK  for  the  purpose  of  Northern  Ireland  can  be  a  concerned  member  state  (not  a 
reference member state) for medicines going through the decentralized or mutual recognition procedure. Northern Ireland can also be included within the 
scope of the centralized procedure. 

Any  marketing  authorizations  granted  by  the  MHRA  under  the  decentralized  or  mutual  recognition  procedure  before  Brexit  became  national 
marketing  authorizations  covering  the  whole  of  the  UK.  Centrally  authorized  products  were  converted  to  a  UKMA(GB)  on  January  1,  2021  unless  the 
marketing authorization holder informed the MHRA otherwise, and centrally authorized products continued to be recognized in Northern Ireland. Until 
December 31, 2023, the European Commission Decision Reliance Procedure (ECDRP) could be used to obtain a UKMA(GB) with the MHRA relying on a 
decision taken by the European Commission on the approval of a new MA under the centralized procedure. Similarly, the MHRA can grant UKMA(UK) or 
UKMA(GB) marketing authorizations under the decentralized and mutual recognition reliance procedure (MRDCRP). 

From January 1, 2024, the ECDRP will be replaced by a new International Recognition Procedure (IRP). The MRDCRP will be incorporated within 
the IRP. ECDRP and MRDCRP submissions received by the MHRA before January 1, 2024 will continue to follow existing procedures, but for ECDRP 
applications the CHMP positive opinion (but not necessarily the European Commission Decision) should be received before December 31, 2023. The IRP 
procedure is open to applicants who have received an authorization for the same product in one of the MHRA’s 

53

 
 
specified Reference Regulators. The current Reference Regulators include (among others) the FDA, EMA and the national competent authorities of the EU 
/ EEA countries. 

The start dates of the data and market exclusivity periods for medicines in the UK will depend on which route it was granted. In respect to orphan 
drugs, the general position under the HMR is 10 years’ orphan market exclusivity is awarded from the date of authorization by the MHRA (which can be 
reduced to six years at the end of the fifth year if the licensing authority is satisfied that the orphan criteria is no longer met). An additional two years may 
be  granted  where  pediatric  data  requirements  are  met.  A  UK-wide  orphan  marketing  authorization  can  only  be  granted  in  the  absence  of  an  active  EU 
designation. 

On  February  27,  2023,  the  UK  and  the  EU  agreed  the  Windsor  Framework  which  addresses  (among  other  things)  the  supply  of  medicines  into 
Northern  Ireland.  It  provides  that  medicines  must  be  approved  and  licensed  on  a  UK-wide  basis  by  the  MHRA  with  the  same  labelling  and  packaging 
across the whole of the UK. The EMA will have no role in the approval of new medicines for Northern Ireland. The arrangement takes effect from January 
1, 2025. 

Since  a  significant  proportion  of  the  regulatory  framework  for  pharmaceutical  products  in  the  UK  covering  the  quality,  safety,  and  efficacy  of 
pharmaceutical  products,  clinical  trials,  marketing  authorization,  commercial  sales,  and  distribution  of  pharmaceutical  products  is  derived  from  EU 
Directives  and  Regulations,  with  some  amendments  made  to  address  the  UK’s  departure  from  the  EU,  Brexit  may  have  a  material  impact  upon  the 
regulatory regime with respect to the development, manufacture, importation, approval and commercialization of product candidates in the UK. However, 
there are new routes to obtaining marketing authorizations available such as the IRP. 

Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, may force us to restrict or delay efforts 

to seek regulatory approval in the UK for our product candidates, which could significantly and materially harm our business.

The design or execution of our ongoing and future clinical trials may not support marketing approval. 

The design or execution of a clinical trial can determine whether its results will support marketing approval, and flaws in the design or execution of 
a clinical trial may not become apparent until the clinical trial is well advanced. We completed a Phase 2a dose-ranging, placebo-controlled trial of LTI-01 
in LPE patients. We may need to investigate higher or lower doses of LTI-01 in future clinical trials to establish efficacy and safety. Additionally, as no 
drug has been approved for LPE, our Phase 2a primary endpoint of treatment failure, defined as death or referral to surgery by a specific criteria checklist 
within seven days of commencing treatment may not be considered an appropriate endpoint for approval by the regulatory authorities. The trial results did 
not show statistical significance on the primary endpoint. Additionally, our highest dose of LTI-01 in this trial showed a lower effect than the other LTI-01 
doses tested. Based on the results of this trial, we expect to investigate LTI-01 in a Phase 2b dose-ranging, placebo-controlled clinical trial with a lower
dose  to  establish  efficacy  and  safety.  Even  with  additional  clinical  trial  testing  with  a  modified  primary  endpoint,  we  may  never  be  successful  in 
demonstrating sufficient results to support marketing approval. 

Additionally, in some instances, there can be significant variability in safety or efficacy results between different clinical trials with the same product 
candidate  due  to  numerous  factors,  including  differences  in  trial  protocols,  size  and  type  of  the  patient  populations,  variable  adherence  to  the  dosing 
regimen or other protocol requirements and the rate of dropout among clinical trial participants. We do not know whether any clinical trials we conduct will 
demonstrate consistent or adequate efficacy and safety to obtain marketing approval to market our product candidates. 

Further,  the  FDA  and  comparable  foreign  regulatory  authorities  have  substantial  discretion  in  the  approval  process  and  in  determining  when  or 
whether marketing approval will be obtained for any of our product candidates. Our product candidates may not be approved even if they achieve their 
primary endpoints in future Phase 3 clinical trials or registrational trials. The FDA or comparable foreign regulatory authorities may disagree with our trial 
designs and our interpretation of data from clinical trials or preclinical studies. In addition, any of these regulatory authorities may change requirements for 
the approval of a product candidate even after reviewing and providing comments or advice on a protocol for a pivotal Phase 3 or registrational clinical 
trial. In addition, any of these regulatory authorities may also approve a product candidate for fewer or more limited indications than we request or may 
grant approval contingent on the performance of costly post-marketing clinical trials or a more restrictive label than we expect (e.g., 

54

 
 
Boxed Warning). Similarly, the FDA or comparable foreign regulatory authorities may not approve the labeling claims that we believe would be necessary 
or desirable for the successful commercialization of our product candidates, if approved. 

Delays  in  patient  enrollment  may  result  in  increased  costs  or  may  affect  the  timing  or  outcome  of  our  future  clinical  trials,  which  could  prevent 

completion of these trials and adversely affect our ability to advance the development of our product candidates. 

If  the  FDA  or  comparable  foreign  regulatory  authorities  approve  generic  or  competitor  versions  of  any  of  our  drugs  that  receive  marketing 
approval, or such authorities do not grant our drugs appropriate periods of data or market exclusivity before approving generic or competitor versions 
of our drugs, the sales of our drugs could be adversely affected. 

Once an NDA is approved, the drug covered thereby becomes a “reference-listed drug” in the FDA’s publication, “Approved Drug Products with 
Therapeutic Equivalence Evaluations.” Manufacturers may seek approval of generic versions of reference-listed drugs through submission of ANDAs in 
the U.S. In support of an ANDA, a generic manufacturer need not conduct clinical trials demonstrating safety and efficacy. Rather, the applicant generally 
must show that its drug has the same active ingredient(s), dosage form, strength, route of administration and conditions of use or labeling as the reference-
listed drug and that the generic version is bioequivalent to the reference-listed drug, meaning it is absorbed in the body at the same rate and to the same 
extent.  Generic  drugs  may  be  significantly  less  costly  to  bring  to  market  than  the  reference-listed  drug  and  companies  that  produce  generic  drugs  are 
generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales of any branded product 
or reference-listed drug is typically lost to the generic drug.

The  FDA  may  not  approve  an  ANDA  for  a  generic  drug  until  any  applicable  period  of  non-patent  exclusivity  for  the  reference-listed  drug  has 
expired. The Federal Food, Drug, and Cosmetic Act, or the FDCA, provides a period of five years of non-patent exclusivity for a new drug containing a 
new chemical entity, or NCE. Specifically, in cases where such exclusivity has been granted, an ANDA may not be filed with the FDA and the FDA may 
not approve the application until the expiration of five years unless the submission is accompanied by a Paragraph IV certification that a patent covering the
reference-listed drug is either invalid, will not be infringed by the generic drug, or unenforceable, in which case the applicant may submit its application 
four years following approval of the reference-listed drug. Manufacturers may seek to launch these generic drugs following the expiration of the marketing 
exclusivity period, even if we still have patent protection for our drug. 

Competition that our drugs may face from generic or competitor versions of our drugs could materially and adversely impact our future revenue,
profitability and cash flows and substantially limit our ability to obtain a return on the investments we have made in those drug candidates. Our future 
revenues, profitability and cash flows could also be materially and adversely affected and our ability to obtain a return on the investments we have made in 
those drug candidates may be substantially limited if our drugs, if and when approved, are not afforded the appropriate periods of non-patent exclusivity. 

Risks Related to Reimbursement, Healthcare Regulations and Ongoing Regulatory Compliance 

Even if we receive regulatory approval of any product candidates, we will be subject to ongoing regulatory obligations and continued regulatory 
review,  which  may  result  in  significant  additional  expense  and  we  may  be  subject  to  penalties  if  we  fail  to  comply  with  regulatory  requirements  or 
experience unanticipated problems with our product candidates, if approved. 

If  any  of  our  product  candidates  are  approved,  they  will  be  subject  to  ongoing  regulatory  requirements  for  manufacturing,  labeling,  packaging, 
distribution,  adverse  event  reporting,  storage,  advertising,  promotion,  sampling,  record-keeping,  conduct  of  post-marketing  studies  and  submission  of 
safety,  efficacy  and  other  post-market  information,  including  both  federal  and  state  requirements  in  the  U.S.  and  requirements  of  comparable  foreign
regulatory authorities. In addition, we will be subject to continued compliance with good manufacturing practices, or cGMP, and good clinical practices, or 
GCP, requirements for any clinical trials that we conduct post-approval.

55

 
 
 Manufacturers and their facilities are required to comply with extensive FDA and comparable foreign regulatory authority requirements, including 
ensuring that quality control and manufacturing procedures conform to cGMP regulations. As such, we and our contract manufacturers will be subject to 
continual  review  and  inspections  to  assess  compliance  with  cGMP  and  adherence  to  commitments  made  in  any  marketing  application,  and  previous 
responses  to  inspection  observations.  Accordingly,  we  and  others  with  whom  we  work  must  continue  to  expend  time,  money,  and  effort  in  all  areas  of 
regulatory compliance, including manufacturing, production, and quality control. 

Any  regulatory  approvals  that  we  receive  for  our  product  candidates  may  be  subject  to  limitations  on  the  approved  indicated  uses  for  which  the 
product may be marketed or to the conditions of approval, contain requirements for potentially costly post-marketing testing, including Phase 4 clinical 
trials  and  surveillance  to  monitor  the  safety  and  efficacy  of  the  product  candidate,  or  include  specific  safety-related  label  warnings  that  could  affect 
marketing  efforts.  The  FDA  may  also  require  a  risk  evaluation  and  mitigation  strategies,  or  REMS,  program  as  a  condition  of  approval  of  our  product 
candidates, which could entail requirements for long-term patient follow-up, a medication guide, physician communication plans or additional elements to 
ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign 
regulatory authority approves our product candidates, we will have to comply with requirements including submissions of safety and other post-marketing 
information and reports and registration. 

The FDA and comparable foreign regulatory agencies may initiate consent decrees or withdraw approval if compliance with regulatory requirements 
and  standards  is  not  maintained  or  if  problems  occur  after  the  product  reaches  the  market.  Later  discovery  of  previously  unknown  problems  with  our 
product candidates, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or 
failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market 
studies or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential 
consequences include, among other things: 

•

•

•

•

•

rescinding approval of the application, restrictions on the marketing or manufacturing of our products, withdrawal of the product from the 
market or voluntary or mandatory product recalls; 

fines, warning letters or holds on clinical trials; 

refusal by the FDA or a comparable foreign regulatory agency to approve pending applications or supplements to approved applications filed 
by us or suspension or revocation of license approvals; 

product seizure or detention or refusal to permit the import or export of our product candidates; and 

injunctions or the imposition of civil or criminal penalties. 

The FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market, and similar restrictions apply 
in foreign jurisdictions. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label. However, 
companies may share truthful and not misleading information that is not inconsistent with the labeling, if certain conditions are met. The FDA and other 
agencies, including the Department of Justice, actively enforce the laws and regulations prohibiting the promotion of false or misleading information or 
unapproved uses and a company that is found to have improperly promoted the product may be subject to significant liability. The policies of the FDA and 
of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of 
our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative 
action, either in the U.S. or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or 
if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain 
profitability. 

Even if we are able to commercialize any product candidate, such product candidate may become subject to unfavorable pricing regulations, 

third-party coverage and reimbursement policies or healthcare reform initiatives, which would harm our business. 

The regulations that govern marketing approval, pricing, coverage and reimbursement for new drugs vary widely from country to country. Some 

countries require approval of the sale price of a drug before it can be marketed. 

56

 
 
In  many  countries,  the  pricing  review  period  begins  after  marketing  approval  is  granted.  In  some  foreign  markets,  prescription  pharmaceutical  pricing 
remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a 
particular  country,  but  then  be  subject  to  price  regulations  that  delay  our  commercial  launch  of  the  product,  possibly  for  lengthy  time  periods,  and
negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to 
recoup our investment in LTI-03 and LTI-01 even if we obtain marketing approval for either product candidate. 

Our  ability  to  commercialize  any  products  successfully  also  will  depend  in  part  on  the  extent  to  which  reimbursement  and  coverage  for  these 
products and related treatments will be available from government authorities, private health insurers and other organizations, and if reimbursement and 
coverage is available, the level of reimbursement and coverage. Government authorities and third-party payors, such as private health insurers and health 
maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A primary trend in the healthcare industry in 
the U.S. and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the 
amount  of  reimbursement  for  particular  medications.  Increasingly,  the  third-party  payors  who  reimburse  patients  or  healthcare  providers,  such  as 
government and private insurance plans, are requiring that drug companies provide them with predetermined discounts from list prices and are seeking to 
reduce the prices charged or the amounts reimbursed for medical products. We cannot be sure that reimbursement will be available for any drug that we 
commercialize and, if reimbursement is available, we cannot be sure as to the level of reimbursement. Reimbursement may impact the demand for, or the 
price of, any product candidate for which we obtain marketing approval. If reimbursement is not available or is available only to limited levels, we may not 
be able to successfully commercialize any product candidate for which we obtain marketing approval. 

There may be significant delays in obtaining reimbursement for newly approved drugs, and coverage may be more limited than the purposes for 
which the drug is approved by the FDA or comparable foreign regulatory authorities. Moreover, eligibility for reimbursement does not imply that any drug 
will be reimbursed in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement 
levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according 
to  the  use  of  the  drug  and  the  clinical  setting  in  which  it  is  used,  may  be  based  on  reimbursement  levels  already  set  for  lower  cost  drugs,  may  be 
incorporated into existing payments for other services and may reflect budgetary constraints or imperfections in Medicare data. Net prices for drugs may be 
reduced  by  mandatory  discounts  or  rebates  required  by  government  healthcare  programs  or  private  payors  and  by  any  future  relaxation  of  laws  that 
presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. Third-party payors often rely upon Medicare 
coverage policy and payment limitations in setting their own reimbursement rates. Our inability to promptly obtain coverage and adequate reimbursement 
rates from both government-funded and private payors for new products that we develop and for which we obtain marketing approval could have a material 
adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition. 

Recently enacted and future legislation may increase the difficulty and cost for us and our future collaborators to obtain marketing approval of 
and  commercialize  our  product  candidates  and  affect  the  prices  we,  or  they,  may  obtain  for  any  products  that  are  approved  in  the  U.S.  or  foreign 
jurisdictions. 

In  the  U.S.  and  some  foreign  jurisdictions,  there  have  been  a  number  of  legislative  and  regulatory  changes  and  proposed  changes  regarding  the 
healthcare  system  that  could  prevent  or  delay  marketing  approval  of  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our 
ability, or the ability of any future collaborators, to profitably sell any product candidates for which we, or they, obtain marketing approval. We expect that 
current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional 
downward pressure on the price that we, or any collaborators, may receive for any approved products. If reimbursement of our products is unavailable or 
limited in scope, our business could be materially harmed. 

In  the  U.S.,  the  Medicare  Prescription  Drug,  Improvement,  and  Modernization  Act  of  2003,  or  Medicare  Modernization  Act,  changed  the  way 
Medicare covers and pays for pharmaceutical products. The legislation expanded Medicare coverage for drug purchases by the elderly and introduced a 
new reimbursement methodology based on 

57

 
 
average sales prices for physician-administered drugs. In addition, this legislation provided authority for limiting the number of drugs that will be covered 
in  any  therapeutic  class.  Cost  reduction  initiatives  and  other  provisions  of  this  legislation  could  decrease  the  coverage  and  price  that  we,  or  any  future 
collaborators,  may  receive  for  any  approved  products.  While  the  Medicare  Modernization  Act  applies  only  to  drug  benefits  for  Medicare  beneficiaries, 
private  payors  often  follow  Medicare  coverage  policy  and  payment  limitations  in  setting  their  own  reimbursement  rates.  Therefore,  any  reduction  in 
reimbursement that results from the Medicare Modernization Act may result in a similar reduction in payments from private payors. 

In March 2010, President Obama signed into law the Patient Protection and Affordable Care Act, as amended by the Health Care and Education 
Affordability  Reconciliation  Act,  or  collectively  the  ACA.  In  August  2011,  the  Budget  Control  Act  of  2011,  among  other  things,  created  measures  for
spending reductions by Congress. This legislation resulted in aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which 
will remain in effect through 2031 under the CARES Act. These Medicare sequester reductions were suspended through the end of June 2022, with the full 
2%  cut  resuming  thereafter.  The  American  Taxpayer  Relief  Act  of  2012,  among  other  things,  reduced  Medicare  payments  to  several  providers  and 
increased  the  statute  of  limitations  period  for  the  government  to  recover  overpayments  to  providers  from  three  to  five  years.  These  laws  may  result  in 
additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for our product candidates for which we may 
obtain  regulatory  approval  or  the  frequency  with  which  any  such  product  candidate  is  prescribed  or  used.  Indeed,  under  current  legislation,  the  actual 
reductions in Medicare payments may vary up to 4%. 

Since  enactment  of  the  ACA,  there  have  been,  and  continue  to  be,  numerous  legal  challenges  and  Congressional  actions  to  repeal  and  replace 
provisions  of  the  law.  For  example,  with  enactment  of  the  Tax  Cuts  and  Jobs  Act  of  2017,  or  the  TCJA,  which  was  signed  by  President  Trump  on 
December 22, 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of 
health insurance, became effective in 2019. 

On November 10, 2020, the Supreme Court heard oral arguments to a case challenging the ACA. On February 10, 2021, the Biden Administration 
withdrew the federal government’s support for overturning the ACA. On June 17, 2021, the Supreme Court rejected this challenge to the ACA. Litigation 
and legislation over the ACA are likely to continue, with unpredictable and uncertain results. 

The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including directing federal agencies with 
authorities and responsibilities under the ACA to waive, defer, grant exemptions from, or delay the implementation of any provision of the ACA that would 
impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. 
On January 28, 2021, however, President Biden issued a new Executive Order which directs federal agencies to reconsider rules and other policies that 
limit  Americans’  access  to  health  care  and  consider  actions  that  will  protect  and  strengthen  that  access.  This  Executive  Order  also  directs  the  U.S. 
Department  of  Health  and  Human  Services  to  create  a  special  enrollment  period  for  the  Health  Insurance  Marketplace  in  response  to  the  COVID-19 
pandemic. We cannot predict how federal agencies will respond to such Executive Orders. 

We expect that these healthcare reforms, as well as other healthcare reform measures that may be adopted in the future, may result in additional 
reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on 
the price that we receive for any approved product and/or the level of reimbursement physicians receive for administering any approved product we might 
bring to market. Reductions in reimbursement levels may negatively impact the prices we receive or the frequency with which our products are prescribed 
or administered. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private 
payors.  Accordingly,  such  reforms,  if  enacted,  could  have  an  adverse  effect  on  anticipated  revenue  from  product  candidates  that  we  may  successfully 
develop and for which we may obtain marketing approval and may affect our overall financial condition and ability to develop or commercialize product 
candidates.

Our relationships with healthcare providers and physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse 
and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and 
diminished profits and future earnings. 

58

 
 
Healthcare providers, physicians and third-party payors in the U.S. and elsewhere play a primary role in the recommendation and prescription of 
biopharmaceutical products. Arrangements with third-party payors and customers can expose biopharmaceutical manufacturers to broadly applicable fraud 
and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act, or 
FCA,  which  may  constrain  the  business  or  financial  arrangements  and  relationships  through  which  such  companies  sell,  market  and  distribute 
biopharmaceutical products. In particular, the research of our product candidates, as well as the promotion, sales and marketing of healthcare items and 
services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing
and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring
and  commission(s),  certain  customer  incentive  programs  and  other  business  arrangements  generally.  Activities  subject  to  these  laws  also  involve  the 
improper use of information obtained in the course of patient recruitment for clinical trials. The applicable federal, state and foreign healthcare laws and 
regulations laws that may affect our ability to operate include, but are not limited to: 

•

•

•

•

the federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any 
remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or 
in return for, either the referral of an individual, or the purchase, lease, order or recommendation of any good, facility, item or service for 
which  payment  may  be  made,  in  whole  or  in  part,  under  a  federal  healthcare  program,  such  as  the  Medicare  and  Medicaid  programs.  A 
person or entity can be found guilty of violating the statute without actual knowledge of the statute or specific intent to violate it. In addition, 
a claim submitted for payment to any federal health care program that includes items or services that were made as a result of a violation of 
the  federal  Anti-Kickback  Statute  constitutes  a  false  or  fraudulent  claim  for  purposes  of  the  FCA.  The  Anti-Kickback  Statute  has  been 
interpreted  to  apply  to  arrangements  between  biopharmaceutical  manufacturers  on  the  one  hand  and  prescribers,  purchasers,  group 
purchasing organizations, and formulary managers, among others, on the other. There are a number of statutory exceptions and regulatory 
safe harbors protecting some common activities from prosecution; 

the  federal  civil  and  criminal  false  claims  laws,  including  the  FCA,  and  civil  monetary  penalty  laws  which  prohibit,  among  other  things, 
individuals or entities from knowingly presenting, or causing to be presented, false, fictitious or fraudulent claims for payment to, or approval 
by  Medicare,  Medicaid,  or  other  federal  healthcare  programs;  knowingly  making,  using  or  causing  to  be  made  or  used  a  false  record  or 
statement  material  to  a  false  or  fraudulent  claim  or  an  obligation  to  pay  or  transmit  money  or  property  to  the  federal  government;  or 
knowingly  concealing  or  knowingly  and  improperly  avoiding  or  decreasing  or  concealing  an  obligation  to  pay  money  to  the  federal 
government.  A  claim  that  includes  items  or  services  resulting  from  a  violation  of  the  federal  Anti-Kickback  Statute  constitutes  a  false  or 
fraudulent  claim  under  the  FCA.  Manufacturers  can  be  held  liable  under  the  FCA  even  when  they  do  not  submit  claims  directly  to 
government payors if they are deemed to “cause” the submission of false or fraudulent claims. The FCA also permits a private individual 
acting as a “whistleblower” to bring qui tam actions on behalf of the federal government alleging violations of the FCA and to share in any 
monetary recovery; 

the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal statutes that 
prohibit  knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or  obtain,  by 
means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control 
of,  any  healthcare  benefit  program,  regardless  of  the  payor  (e.g.,  public  or  private)  and  knowingly  and  willfully  falsifying,  concealing  or 
covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment 
for, healthcare benefits, items or services relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity can be 
found guilty of violating HIPAA without actual knowledge of the statute or specific intent to violate it; 

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective 
implementing regulations, which impose, among other things, requirements relating to the privacy, security and transmission of individually 
identifiable  health  information  on  certain  covered  healthcare  providers,  health  plans,  and  healthcare  clearinghouses,  known  as  covered 
entities, as well as their respective “business associates,” those independent contractors or agents of covered entities that perform services for 
covered entities that involve the creation, use, receipt, 

59

 
 
•

•

•

maintenance  or  disclosure  of  individually  identifiable  health  information.  HITECH  also  created  new  tiers  of  civil  monetary  penalties,
amended  HIPAA  to  make  civil  and  criminal  penalties  directly  applicable  to  business  associates,  and  gave  state  attorneys  general  new 
authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and 
costs associated with pursuing federal civil actions; 

the federal Physician Payments Sunshine Act, created under the ACA, and its implementing regulations, which require some manufacturers 
of  drugs,  devices,  biologics  and  medical  supplies  for  which  payment  is  available  under  Medicare,  Medicaid  or  the  Children’s  Health 
Insurance  Program  (with  certain  exceptions)  to  report  annually  to  the  Centers  for  Medicare  &  Medicaid  services,  or  CMS,  information 
related  to  payments  or  other  transfers  of  value  made  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and 
chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. 
Effective January 1, 2022, these reporting obligations were extended to include transfers of value made in the previous year to certain non-
physician providers such as physician assistants and nurse practitioners; 

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm 
consumers; and 

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing 
arrangements and claims involving healthcare items or services reimbursed by third-party payors, including private insurers, the Travel Act 
of 1961, or the Travel Act, which has been used as a tool in the health care context to target kickback schemes prohibited under state law 
involving  private  insurance  that  would  not  otherwise  be  prohibited  under  federal  law  and  may  be  broader  in  scope  than  their  federal 
equivalents;  state  and  foreign  laws  that  require  biopharmaceutical  companies  to  comply  with  the  biopharmaceutical  industry’s  voluntary 
compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may 
be  made  to  healthcare  providers  and  other  potential  referral  sources;  state  and  foreign  laws  that  require  drug  manufacturers  to  report 
information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or drug 
pricing; state and local laws that require the registration of biopharmaceutical sales representatives; and state and foreign laws governing the 
privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are 
not preempted by HIPAA, thus complicating compliance efforts. 

The distribution of biopharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, 
storage  and  security  requirements  intended  to  prevent  the  unauthorized  sale  of  biopharmaceutical  products.  There  are  also  federal  and  state  consumer 
deception laws, with which we must comply. 

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially 
in light of the lack of applicable precedent and regulations. Ensuring business arrangements comply with applicable healthcare laws, as well as responding 
to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business. 

It is possible that governmental and enforcement authorities will conclude that our business practices may not comply with current or future statutes, 
regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we 
are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of 
significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  disgorgement,  imprisonment,  reputational  harm,  possible  exclusion  from 
participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional 
reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance 
with  these  laws.  Further,  if  any  of  the  physicians  or  other  healthcare  providers  or  entities  with  whom  we  expect  to  do  business  are  found  not  to  be  in 
compliance  with  applicable  laws,  they  may  be  subject  to  significant  criminal,  civil  or  administrative  sanctions,  including  exclusions  from  government 
funded healthcare programs. Any action for violation of these laws, even if successfully defended, could cause a biopharmaceutical manufacturer to incur 
significant legal 

60

 
 
expenses  and  divert  management’s  attention  from  the  operation  of  the  business.  Prohibitions  or  restrictions  on  sales  or  withdrawal  of  future  marketed 
products could materially affect business in an adverse way. 

The prices of prescription pharmaceuticals in the U.S. and foreign jurisdictions are subject to considerable legislative and executive actions and 

could impact the prices we obtain for our products, if and when licensed. 

The prices of prescription pharmaceuticals have also been the subject of considerable discussion in the U.S. There have been several recent U.S. 
congressional  inquiries,  as  well  as  proposed  and  enacted  state  and  federal  legislation  designed  to,  among  other  things,  bring  more  transparency  to 
pharmaceutical  pricing,  review  the  relationship  between  pricing  and  manufacturer  patient  programs,  and  reduce  the  costs  of  pharmaceuticals  under 
Medicare  and  Medicaid.  In  2020,  President  Trump  issued  several  executive  orders  intended  to  lower  the  costs  of  prescription  products  and  certain 
provisions  in  these  orders  have  been  incorporated  into  regulations.  These  regulations  include  an  interim  final  rule  implementing  a  most  favored  nation 
model  for  prices  that  would  tie  Medicare  Part  B  payments  for  certain  physician-administered  pharmaceuticals  to  the  lowest  price  paid  in  other 
economically advanced countries, effective January 1, 2021. That rule, however, has been subject to a nationwide preliminary injunction and, on December 
29, 2021, CMS issued a final rule to rescind it. With issuance of this rule, CMS stated that it will explore all options to incorporate value into payments for 
Medicare Part B pharmaceuticals and improve beneficiaries’ access to evidence-based care. 

In  addition,  in  October  2020,  HHS  and  the  FDA  published  a  final  rule  allowing  states  and  other  entities  to  develop  a  Section  804  Importation 
Program, or SIP, to import certain prescription drugs from Canada into the U.S. The final rule is currently the subject of ongoing litigation, but at least six 
states (Vermont, Colorado, Florida, Maine, New Mexico, and New Hampshire) have passed laws allowing for the importation of drugs from Canada with
the  intent  of  developing  SIPs  for  review  and  approval  by  the  FDA.  Further,  on  November  20,  2020,  HHS  finalized  a  regulation  removing  safe  harbor 
protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, 
unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 
1, 2023 in response to ongoing litigation. The final rule would eliminate the current safe harbor for Medicare drug rebates and create new safe harbors for 
beneficiary point-of-sale discounts and pharmacy benefit manager, or PBM, services fees. It was originally set to go into effect on January 1, 202, but with 
the passage of the Inflation Reduction Act has been delayed by Congress to January 1, 2032. 

On July 9, 2021, President Biden signed Executive Order 14063, which focuses on, among other things, the price of pharmaceuticals. The Order 
directs  the  Department  of  Health  and  Human  Services,  or  HHS,  to  create  a  plan  within  45  days  to  combat  “excessive  pricing  of  prescription 
pharmaceuticals and enhance domestic pharmaceutical supply chains, to reduce the prices paid by the federal government for such pharmaceuticals, and to 
address the recurrent problem of price gouging.” On September 9, 2021, HHS released its plan to reduce pharmaceutical prices. The key features of that 
plan  are  to:  (a)  make  pharmaceutical  prices  more  affordable  and  equitable  for  all  consumers  and  throughout  the  health  care  system  by  supporting 
pharmaceutical  price  negotiations  with  manufacturers;  (b)  improve  and  promote  competition  throughout  the  prescription  pharmaceutical  industry  by 
supporting  market  changes  that  strengthen  supply  chains,  promote  biosimilars  and  generic  drugs,  and  increase  transparency;  and  (c)  foster  scientific 
innovation  to  promote  better  healthcare  and  improve  health  by  supporting  public  and  private  research  and  making  sure  that  market  incentives  promote 
discovery of valuable and accessible new treatments. 

More recently, on August 16, 2022, the Inflation Reduction Act of 2022, or IRA, was signed into law by President Biden. The new legislation has 
implications for Medicare Part D, which is a program available to individuals who are entitled to Medicare Part A or enrolled in Medicare Part B to give 
them the option of paying a monthly premium for outpatient prescription drug coverage. Among other things, the IRA requires manufacturers of certain 
drugs  to  engage  in  price  negotiations  with  Medicare  (beginning  in  2026),  with  prices  that  can  be  negotiated  subject  to  a  cap;  imposes  rebates  under 
Medicare Part B and Medicare Part D to penalize price increases that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount 
program with a new discounting program (beginning in 2025). The IRA permits the Secretary of the Department of Health and Human Services (HHS) to 
implement many of these provisions through guidance, as opposed to regulation, for the initial years. 

Specifically,  with  respect  to  price  negotiations,  Congress  authorized  Medicare  to  negotiate  lower  prices  for  certain  costly  single-source  drug  and 

biologic products that do not have competing generics or biosimilars and are 

61

 
 
reimbursed under Medicare Part B and Part D. CMS may negotiate prices for ten high-cost drugs paid for by Medicare Part D starting in 2026, followed by 
15 Part D drugs in 2027, 15 Part B or Part D drugs in 2028, and 20 Part B or Part D drugs in 2029 and beyond. This provision applies to drug products that 
have  been  approved  for  at  least  9  years  and  biologics  that  have  been  licensed  for  13  years,  but  it  does  not  apply  to  drugs  and  biologics  that  have  been 
approved for a single rare disease or condition. Nonetheless, since CMS may establish a maximum price for these products in price negotiations, we would 
have been fully at risk of government action if our products were the subject of Medicare price negotiations. Moreover, given the risk that could be the 
case, these provisions of the IRA may also have further heightened the risk that we would not have been able to achieve the expected return on our drug 
products or full value of our patents protecting our products if prices are set after such products had been on the market for nine years. 

Further, the legislation subjects drug manufacturers to civil monetary penalties and a potential excise tax for failing to comply with the legislation by 
offering a price that is not equal to or less than the negotiated “maximum fair price” under the law or for taking price increases that exceed inflation. The 
legislation also requires manufacturers to pay rebates for drugs in Medicare Part D whose price increases exceed inflation. The new law also caps Medicare 
out-of-pocket drug costs at an estimated $4,000 a year in 2024 and, thereafter beginning in 2025, at $2,000 a year. In addition, the IRA potentially raises 
legal risks with respect to individuals participating in a Medicare Part D prescription drug plan who may experience a gap in coverage if they required 
coverage  above  their  initial  annual  coverage  limit  before  they  reached  the  higher  threshold,  or  “catastrophic  period”  of  the  plan.  Individuals  requiring 
services exceeding the initial annual coverage limit and below the catastrophic period, must pay 100% of the cost of their prescriptions until they reach the 
catastrophic  period.  Among  other  things,  the  IRA  contains  many  provisions  aimed  at  reducing  this  financial  burden  on  individuals  by  reducing  the  co-
insurance  and  co-payment  costs,  expanding  eligibility  for  lower  income  subsidy  plans,  and  price  caps  on  annual  out-of-pocket  expenses,  each  of  which 
could have potential pricing and reporting implications. 

At  the  state  level,  individual  states  are  increasingly  aggressive  in  passing  legislation  and  implementing  regulations  designed  to  control 
pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and 
marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In 
addition, regional healthcare organizations and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products 
and which suppliers will be included in their prescription drug and other healthcare programs. These measures could reduce the ultimate demand for our 
products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in
the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in 
reduced demand for our product candidates or additional pricing pressures. 

In the E.U., similar political, economic, and regulatory developments may affect our ability to profitably commercialize our product candidates, if 
approved. In markets outside of the U.S. and the E.U., reimbursement and healthcare payment systems vary significantly by country and many countries 
have instituted price ceilings on specific products and therapies. In many countries, including those of the E.U., the pricing of prescription pharmaceuticals 
is subject to governmental control and access. In these countries, pricing negotiations with governmental authorities can take considerable time after the 
receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we or our collaborators may be required to 
conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. If reimbursement of our products is unavailable or 
limited in scope or amount or if pricing is set at unsatisfactory levels, our business could be materially harmed. 

Governments outside of the U.S. tend to impose strict price controls, which may adversely affect our revenues from the sales of our products, if 

any. 

In  most  foreign  countries,  including  the  European  Economic  Area,  or  EEA,  and  the  UK,  the  proposed  pricing  for  certain  drugs  (in  particular, 
prescription-only drugs) is subject to pricing regulations. In the EU, although Directive 89/105/EEC regulates the framework conditions for the pricing of 
medicinal products and Regulation (EU) 2021/2282 on health technology assessment (HTA), to become fully applicable in January 2025, provides for a 
coordinated approach to assessing the benefit of new therapies, the decisions on pricing and cost reimbursement remain in the responsibility of the member 
states. The requirements governing drug pricing and reimbursement vary widely from country to country. For example, the EU provides options for its 
member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices 
of 

62

 
 
medicinal  products  for  human  use.  In  some  countries,  particularly  member  states  of  the  EU,  the  pricing  of  prescription  pharmaceuticals  is  subject  to 
governmental control and other market regulations which could put pressure on the pricing and usage of our product candidates. In these countries, pricing 
negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. In addition, market acceptance 
and sales of our product candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our 
product candidates and may be affected by existing and future health care reform measures. Moreover, there can be considerable pressure by governments 
and  other  stakeholders  on  prices  and  reimbursement  levels,  including  as  part  of  cost  containment  measures.  Political,  economic  and  regulatory 
developments  may  further  complicate  pricing  negotiations,  and  pricing  negotiations  may  continue  after  reimbursement  has  been  obtained.  Reference 
pricing  used  by  various  EU  member  states  and  parallel  distribution,  or  arbitrage  between  low-priced  and  high-priced  member  states,  can  further  reduce 
prices.  A  member  state  may  approve  a  specific  price  for  the  medicinal  product,  or  it  may  instead  adopt  a  system  of  direct  or  indirect  controls  on  the 
profitability  of  the  company  placing  the  medicinal  product  on  the  market.  In  view  of  the  recurring  shortages  of  medicines,  individual  member  states 
(especially  Germany)  have  decided  to  adjust  price  regulations  for  particularly  rare  pediatric  medicinal  products.  In  some  countries,  we,  or  our  future 
collaborators, may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of our product candidates to other available 
therapies  in  order  to  obtain  or  maintain  reimbursement  or  pricing  approval.  There  can  be  no  assurance  that  any  country  that  has  price  controls  or 
reimbursement  limitations  for  biopharmaceutical  products  will  allow  favorable  reimbursement  and  pricing  arrangements  for  any  of  our  products. 
Historically,  products  launched  in  the  EU  do  not  follow  price  structures  of  the  U.S.  and  generally  prices  tend  to  be  significantly  lower.  Publication  of 
discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other 
countries. If pricing is set at unsatisfactory levels or if reimbursement of our products is unavailable or limited in scope or amount, our revenues from sales 
and the potential profitability of any of our product candidates in those countries would be negatively affected. 

Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of 
publication  and  other  countries.  If  reimbursement  of  any  product  candidate  approved  for  marketing  is  unavailable  or  limited  in  scope  or  amount,  or  if 
pricing is set at unsatisfactory levels, our business could be materially harmed. 

EU  drug  marketing  and  reimbursement  regulations  may  materially  affect  our  ability  to  market  and  receive  coverage  for  our  products  in  the 

European member states. 

We intend to seek approval to market our product candidates in both the U.S. and in selected foreign jurisdictions. If we obtain approval in one or 

more foreign jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. 

Much like the federal Anti-Kickback Statute prohibition in the U.S., the provision of benefits or advantages to physicians to induce or encourage the 
prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is also prohibited in the EU. The provision of benefits or 
advantages  to  physicians  is  governed  by  the  national  anti-bribery  laws,  unfair  competition  laws  and  laws  on  advertising  in  the  healthcare  sector  of  EU 
Member States, and in respect of the UK (which is no longer a member of the EU), the UK Bribery Act 2010 and laws on advertising and promotion in the 
pharmaceutical, medical devices and healthcare sectors. Infringement of these laws could result in substantial fines and imprisonment. 

Payments made to physicians in certain EU Member States must be publicly disclosed. The UK has also recently concluded a public consultation on 
introducing new statutory requirements for disclosing industry payments in the healthcare sector. Further, certain company associations have adopted so-
called  transparency  codes,  according  to  which  payments  to  certain  groups  in  the  healthcare  sector  must  be  published  or  are  published  voluntarily. 
Moreover,  agreements  with  physicians  often  must  be  the  subject  of  prior  notification  and  approval  by  the  physician’s  employer,  his  or  her  competent 
professional  organization  and/or  the  regulatory  authorities  of  the  individual  EU  Member  States.  These  requirements  are  provided  in  the  national  laws, 
industry codes or professional codes of conduct, applicable in the EU Member States, as well in as the UK. Failure to comply with these requirements 
could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

We may seek to obtain certain regulatory designations for our product candidates. We may not receive such designations, and even if we do, 

such designation may not lead to a faster development or regulatory review or approval process. 

We  may  seek  to  obtain  breakthrough  therapy  designation,  fast  track  designation,  or  priority  review  designation  for  our  product  candidates.  A 
breakthrough  therapy  is  defined  as  a  drug  that  is  intended,  alone  or  in  combination  with  one  or  more  other  drugs,  to  treat  a  serious  condition,  and 
preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant 
endpoints, such as substantial treatment effects observed early in clinical development. FDA fast track designation is possible for drugs intended for the 
treatment of a serious condition and nonclinical or clinical data demonstrate the potential to address unmet medical need for this condition. In addition, if 
the  FDA  determines  that  a  product  candidate  offers  a  treatment  for  a  serious  condition  and,  if  approved,  the  product  would  provide  a  significant 
improvement in safety or effectiveness, the FDA may designate the product candidate for priority review. Drugs designated as breakthrough therapies by 
the FDA may also be eligible for priority review if supported by clinical data at the time the NDA is submitted to the FDA. 

Such regulatory designations are within the discretion of the FDA, and the FDA may not approve any application that we submit. Even if we were to 
obtain  breakthrough  designation  or  fast  track  designation,  the  FDA  may  subsequently  withdraw  such  designation  if  the  FDA  determines  that  the 
designation no longer meets the conditions for qualification or is no longer supported by data from our clinical development program. In addition, receipt 
of any such designations may not result in a faster development or regulatory review or approval process compared to drugs considered for approval under 
conventional FDA procedures and does not assure ultimate approval by the FDA of any drug candidates so designated. 

Our  employees,  independent  contractors,  consultants,  commercial  partners,  collaborators  and  vendors  may  engage  in  misconduct  or  other 

improper activities, including noncompliance with regulatory standards and requirements. 

We are exposed to the risk of employee fraud or other illegal activity by our employees, independent contractors, consultants, commercial partners, 
collaborators and vendors. Misconduct by these parties could include intentional, reckless and/or negligent conduct that fails to comply with the laws and 
regulations of the FDA, CMS and other similar foreign regulatory bodies, provide true, complete and accurate information to the FDA, CMS and other 
similar foreign regulatory bodies, comply with manufacturing standards we have established, comply with healthcare fraud and abuse laws in the U.S. and 
similar foreign fraudulent misconduct laws, or report financial information or data accurately or to disclose unauthorized activities to us. If we obtain FDA 
approval of any of our product candidates and begin commercializing those products in the U.S., our potential exposure under such laws and regulations 
will increase significantly, and our costs associated with compliance with such laws and regulations will also increase. These laws and regulations may 
impact, among other things, our current activities with principal investigators and research patients, as well as proposed and future sales, marketing and 
education programs. We have adopted a code of business conduct and ethics and maintain a quality management system, but it is not always possible to 
identify and deter misconduct by our employees, independent contractors, consultants, commercial partners and vendors, and the precautions we take to 
detect  and  prevent  this  activity  may  not  be  effective  in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental 
investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any actions are instituted against us and we 
are not successful in defending ourselves or asserting our rights, those actions could result in the imposition of civil, criminal and administrative penalties, 
damages,  monetary  fines,  imprisonment,  disgorgement,  possible  exclusion  from  participation  in  government  healthcare  programs,  additional  reporting 
obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these 
laws, contractual damages, reputational harm, diminished profits and future earnings and the curtailment of our operations. 

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that 

could have a material adverse effect on the success of our business.

We  are  subject  to  numerous  environmental,  health  and  safety  laws  and  regulations,  including  those  governing  laboratory  procedures  and  the 
handling, use, storage, treatment and disposal of hazardous materials and wastes. Our research and development activities involve the use of biological and 
hazardous materials and produce hazardous 

64

 
 
waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or 
injury from these materials, which could cause an interruption of our commercialization efforts, research and development efforts and business operations, 
environmental damage resulting in costly clean-up and liabilities under applicable laws and regulations governing the use, storage, handling and disposal of 
these materials and specified waste products. Although we believe that the safety procedures utilized by our third-party manufacturers for handling and 
disposing  of  these  materials  generally  comply  with  the  standards  prescribed  by  these  laws  and  regulations,  we  cannot  guarantee  that  this  is  the  case  or 
eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damages and such 
liability could exceed our resources and state or federal or other applicable authorities may curtail our use of certain materials and/or interrupt our business 
operations. Furthermore, environmental laws and regulations are complex, change frequently and have tended to become more stringent. We cannot predict 
the impact of such changes and cannot be certain of our future compliance. In addition, we may incur substantial costs in order to comply with current or 
future  environmental,  health  and  safety  laws  and  regulations.  These  current  or  future  laws  and  regulations  may  impair  our  research,  development  or 
production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions. 

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting 
from the use of hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. We do not 
carry  specific  biological  waste  or  hazardous  waste  insurance  coverage,  workers  compensation  or  property  and  casualty  and  general  liability  insurance 
policies that include coverage for damages and fines arising from biological or hazardous waste exposure or contamination, and as such we would have to 
pay the full amount of any resultant liability out of pocket, which could significantly impair our financial condition. 

Additional laws and regulations governing international operations could negatively impact or restrict our operations. 

If  we  expand  our  operations  outside  of  the  U.S.,  we  must  dedicate  additional  resources  to  comply  with  numerous  laws  and  regulations  in  each 
jurisdiction  in  which  we  plan  to  operate.  The  U.S.  Foreign  Corrupt  Practices  Act,  or  the  FCPA,  prohibits  any  U.S.  individual  or  business  entity  from 
paying,  offering,  authorizing  payment  or  offering  of  anything  of  value,  directly  or  indirectly,  to  any  foreign  official,  political  party  or  candidate  for  the 
purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA 
also obligates companies whose securities are listed in the U.S. to comply with certain accounting provisions requiring the company to maintain books and 
records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate 
system of internal accounting controls for international operations. 

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA 
presents particular challenges in the biopharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and 
other hospital employees are considered foreign officials. Certain payments to hospitals and healthcare providers in connection with clinical trials and other 
work  have  been  deemed  to  be  improper  payments  to  government  officials  and  have  led  to  FCPA  enforcement  actions.  Various  laws,  regulations  and 
executive  orders  also  restrict  the  use  and  dissemination  outside  of  the  U.S.,  or  the  sharing  with  certain  non-U.S.  nationals,  of  information  products 
classified for national security purposes, as well as certain products, technology and technical data relating to those products. If we expand our presence 
outside  of  the  U.S.,  it  will  require  us  to  dedicate  additional  resources  to  comply  with  these  laws,  and  these  laws  may  preclude  us  from  developing, 
manufacturing, or selling certain products and product candidates outside of the U.S., which could limit our growth potential and increase our development 
costs. 

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or 

debarment from government contracting. 

We may incur substantial costs in our efforts to comply with evolving global data protection laws and regulations, and any failure or perceived 

failure by us to comply with such laws and regulations may harm our business and operations. 

65

 
 
The global data protection landscape is rapidly evolving, and we may be or become subject to or affected by numerous federal, state and foreign 
laws and regulations, as well as regulatory guidance, governing the collection, use, disclosure, transfer, security and processing of personal data, such as 
information  that  we  collect  about  participants  and  healthcare  providers  in  connection  with  clinical  trials.  Implementation  standards  and  enforcement 
practices are likely to remain uncertain for the foreseeable future, which may create uncertainty in our business, affect our or our service providers’ ability 
to operate in certain jurisdictions or to collect, store, transfer use and share personal data, result in liability or impose additional compliance or other costs 
on us. Any failure or perceived failure by us to comply with federal, state, or foreign laws or self-regulatory standards could result in negative publicity, 
diversion of management time and effort and proceedings against us by governmental entities or others. 

In addition to our operations in the U.S. and our ongoing Phase 1b trial of LTI-03 in IPF patients in the UK, E.U. and Australia, which may be 
subject  to  healthcare  and  other  laws  relating  to  the  privacy  and  security  of  health  information  and  other  personal  information,  we  may  seek  to  conduct 
clinical trials in the EEA and may become subject to additional European data protection laws, regulations and guidelines. The General Data Protection 
Regulation,  (EU)  2016/679,  or  GDPR,  became  effective  on  May  25,  2018,  and  deals  with  the  collection,  use,  storage,  disclosure,  transfer,  or  other 
processing of personal data, including personal health data, regarding individuals in the EEA. The GDPR imposes a broad range of strict requirements on 
companies  subject  to  the  GDPR,  including  requirements  relating  to  having  legal  bases  for  processing  personal  information  relating  to  identifiable 
individuals and transferring such information outside the EEA, including to the U.S., providing details to those individuals regarding the processing of their 
personal health and other sensitive data, obtaining consent to certain processing activities from the individuals to whom the personal data relates, keeping 
personal data secure, having data processing agreements with third parties who process personal data, responding to individuals’ requests to exercise their 
rights in respect of their personal data, reporting security breaches involving personal data to the competent national data protection authority and affected 
individuals, appointing data protection officers, conducting data protection impact assessments, and record-keeping. The GDPR provides for substantial 
penalties to which we could be subject in the event of any non-compliance, including fines of up to 10,000,000 Euros or up to two percent of our total 
worldwide annual revenues, whichever is greater, for certain comparatively minor offenses, or up to 20,000,000 Euros or up to four percent of our total 
worldwide annual revenues, whichever is greater, for more serious offenses. The GDPR also confers a private right of action on data subjects and consumer 
associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the
GDPR. In addition, the GDPR includes restrictions on cross-border data transfers, and recent court decisions and regulatory guidance have substantially 
increased the compliance burden and legal uncertainty associated with transferring the personal data of EEA individuals to third countries outside of the 
EEA whose data protection laws are not believed to be adequate by European standards (although the recent EU-US Data Privacy Framework offers a new 
route for data transfers from the EU to be made lawfully to the US). 

Further, the GDPR provides for opening clauses in certain areas, which enable the legislators of member states of the EU to implement additional 
requirements to the GDPR in national law, whereby national laws may partially deviate from the GDPR and impose different obligations from country to 
country, so that we do not expect to operate in a uniform legal landscape in the EEA. 

Also, as it relates to processing and transfer of genetic, biometric and health data, the GDPR specifically allows national laws to impose additional 
and  more  specific  requirements  or  restrictions,  and  European  laws  have  historically  differed  quite  substantially  in  this  field,  leading  to  additional 
uncertainty. The UK’s decision to leave the EU (and it is important to note that the EEA does not include the UK), often referred to as Brexit, has created 
uncertainty with regard to data protection regulation in the UK and to what extent UK law will diverge from the GDPR in the future. At this point in time, 
the UK Government has incorporated the GDPR into UK law, known as the ‘UK GDPR”, but has also published proposals recently to reform UK data 
protection  law  which  are  going  through  the  UK  Parliament  and  likely  to  become  law  in  2024.  In  the  context  of  international  data  transfers,  European 
Commission  has  issued  adequacy  decisions  which  have  the  effect  of  authorizing  data  transfers  from  the  EEA  to  the  UK  The  UK  Government  and  the 
Information Commissioner’s Office have also published proposals recently to indicate how data transfers between the UK and the rest of the world will be 
regulated now that the UK has left the EU. For instance, the UK Government proposes recognizing more countries as adequate for data transfers as part of 
reducing barriers to data flows—this would include countries not yet authorized by the European Commission. The UK Government has also approved the 
UK Extension to the EU-US Data Privacy Framework for data transfers from the UK to the US. 

66

 
 
The GDPR increases our responsibility and liability in relation to personal data that we process where such processing is subject to the GDPR, and 
we may be required to put in place additional mechanisms and safeguards to ensure compliance with the GDPR, including as implemented by individual 
countries. Compliance with the GDPR is a rigorous and time-intensive process that may increase our cost of doing business or require us to change our 
business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection 
with  our  European  activities.  We  face  uncertainty  as  to  whether  our  efforts  to  comply  with  our  obligations  under  European  data  protection  laws  are 
sufficient, and personal data transfers from the EEA to the U.S. (which include accessing in the U.S. personal data from EEA individuals, even if the data 
actually remains stored in the EEA) may face particular scrutiny. If we are investigated by a European data protection authority, we may face fines and 
other penalties. Any such investigation or charges by European data protection authorities could have a negative effect on our existing business and on our 
ability  to  attract  and  retain  new  clients  or  biopharmaceutical  partners.  We  may  also  experience  hesitancy,  reluctance,  or  refusal  by  European  or  multi-
national clients or biopharmaceutical partners to continue to use our products and solutions due to the potential risk exposure as a result of the current (and, 
in particular, future) data protection obligations imposed on them by certain data protection authorities in interpretation of current law, including the GDPR. 
Such  clients  or  biopharmaceutical  partners  may  also  view  any  alternative  approaches  to  compliance  as  being  too  costly,  too  burdensome,  too  legally 
uncertain, or otherwise objectionable and therefore decide not to do business with us. Any of the forgoing could materially harm our business, prospects, 
financial condition and results of operations. 

We  are  subject  to  certain  U.S.  and  foreign  anti-corruption,  anti-money  laundering,  export  control,  sanctions  and  other  trade  laws  and 

regulations. We can face serious consequences for violations. 

Among other matters, U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions and other trade laws and regulations, which 
are  collectively  referred  to  as  Trade  Laws,  prohibit  companies  and  their  employees,  agents,  clinical  research  organizations,  legal  counsel,  accountants, 
consultants,  contractors,  and  other  partners  from  authorizing,  promising,  offering,  providing,  soliciting,  or  receiving  directly  or  indirectly,  corrupt  or 
improper payments or anything else of value to or from recipients in the public or private sector. Violations of Trade Laws can result in substantial criminal 
fines and civil penalties, imprisonment, the loss of trade privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm 
and other consequences. We have direct or indirect interactions with officials and employees of government agencies or government affiliated hospitals, 
universities and other organizations. We also expect our non-U.S. activities to increase in time. We plan to engage third parties for clinical trials and/or to 
obtain necessary permits, licenses, patent registrations, and other regulatory approvals and we can be held liable for the corrupt or other illegal activities of 
our personnel, agents or partners, even if we do not explicitly authorize or have prior knowledge of such activities. 

Inadequate funding for the FDA, the SEC and other government agencies, including from government shut downs, or other disruptions to these
agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being 
developed  or  commercialized  in  a  timely  manner  or  otherwise  prevent  those  agencies  from  performing  normal  business  functions  on  which  the 
operation of our business may rely, which could negatively impact our business. 

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, 
ability  to  hire  and  retain  key  personnel  and  accept  the  payment  of  user  fees,  and  statutory,  regulatory  and  policy  changes.  Average  review  times  at  the 
agency have fluctuated in recent years as a result. Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates 
to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. In addition, government funding of the SEC 
and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political 
process, which is inherently fluid and unpredictable. 

Disruptions  at  the  FDA  and  other  agencies  may  also  slow  the  time  necessary  for  new  product  candidates  to  be  reviewed  and/or  approved  by 
necessary government agencies, which would adversely affect our business. For example, over the last several years the U.S. government has shut down 
several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and 
stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our 
regulatory submissions, which could have a material adverse effect on our business. 

67

 
 
Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and 
continue our operations. 

The same is true of disruptions related to public health emergencies that have occurred or that may occur in the future. For example, during the 
COVID-19 pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections 
for their applications. The FDA has now indicated that it can and will conduct timely reviews of applications for medical products in line with its user fee 
performance  goals,  including  conducting  mission  critical  domestic  and  foreign  inspections  to  ensure  compliance  of  manufacturing  facilities  with  FDA 
quality standards. However, in the event of a resurgence of the COVID-19 pandemic or another similar public health emergency in the future, the FDA may 
not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the U.S. facing similar circumstances may 
adopt similar restrictions or other policy measures in response to future emergencies and may also experience delays in their regulatory activities. 

The application of newly developed artificial intelligence and other technologies which are widely anticipated to reduce the development time to 
bring new products to market may materially increase the volume of applications for product approval to the FDA compared to historical application levels. 
If this increased application volume materializes and additional staff and resources are not allocated to the FDA, the FDA may not be able to continue its 
current pace of application reviews and review timelines could be extended. Regulatory authorities outside the U.S. facing similar increases in application 
volume  may  also  experience  delays  in  their  regulatory  activities.  Accordingly,  if  a  prolonged  government  shutdown  or  other  disruption  occurs,  or  the 
volume of application to the FDA for new product candidates increases materially, it could significantly impact the ability of the FDA to timely review and 
process our regulatory submissions, which could have a material adverse effect on our business. Future shutdowns or other disruptions could also affect
other government agencies such as the SEC, which may also impact our business by delaying review of our public filings, to the extent such review is 
necessary, and our ability to access the public markets. 

Risks Related to Our Dependence on Third Parties 

We rely on third parties to conduct certain aspects of our clinical trials and preclinical studies. If these third parties do not successfully carry out 
their  contractual  duties,  meet  expected  deadlines  or  comply  with  regulatory  requirements,  we  may  not  be  able  to  obtain  regulatory  approval  of  or 
commercialize any potential product candidates. 

We depend upon third parties to conduct certain aspects of our clinical trials and preclinical studies, under agreements with universities, medical 
institutions, CROs, strategic collaborators and others. We expect to have to negotiate budgets and contracts with such third parties, which may result in 
delays to our development timelines and increased costs. 

We  will  rely  especially  heavily  on  third  parties  over  the  course  of  our  clinical  trials,  and,  as  a  result,  will  have  limited  control  over  the  clinical 
investigators  and  limited  visibility  into  their  day-to-day  activities,  including  with  respect  to  their  compliance  with  the  approved  clinical  protocol. 
Nevertheless,  we  are  responsible  for  ensuring  that  each  of  our  trials  is  conducted  in  accordance  with  the  applicable  protocol,  legal  and  regulatory 
requirements and scientific standards and our reliance on third parties does not relieve us of our regulatory responsibilities. We and these third parties are 
required  to  comply  with  GCP  or  other  requirements,  which  are  regulations  and  guidelines  enforced  by  the  FDA  and  comparable  foreign  regulatory 
authorities  for  product  candidates  in  clinical  development.  Regulatory  authorities  enforce  these  GCP  requirements  through  periodic  inspections  of  trial 
sponsors,  clinical  investigators  and  trial  sites.  If  we  or  any  of  these  third  parties  fail  to  comply  with  applicable  GCP  requirements,  the  clinical  data 
generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to suspend or terminate 
these  trials  or  perform  additional  clinical  trials  or  preclinical  studies  before  approving  our  marketing  applications.  We  cannot  be  certain  that,  upon 
inspection, such regulatory authorities will determine that any of our clinical trials comply with the GCP requirements. 

Our failure or any failure by these third parties to comply with these regulations or to recruit a sufficient number of patients may require us to repeat

clinical trials, which would delay the regulatory approval process. Moreover, our 

68

 
 
business may be implicated if any of these third parties violates federal or state fraud and abuse or false claims laws and regulations or healthcare privacy 
and security laws. 

Any  third  parties  conducting  aspects  of  our  clinical  trials  or  preclinical  studies  will  not  be  our  employees  and,  except  for  remedies  that  may  be 
available to us under our agreements with such third parties, we cannot control whether or not they devote sufficient time and resources to our clinical 
programs and preclinical studies. These third parties may also have relationships with other commercial entities, including our competitors, for whom they 
may also be conducting clinical trials or other product development activities, which could affect their performance on our behalf. If these third parties do 
not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the 
preclinical or clinical data they obtain is compromised due to the failure to adhere to our protocols or regulatory requirements or for other reasons or if due 
to federal or state orders they are unable to meet their contractual and regulatory obligations, our development timelines, including clinical development 
timelines,  may  be  extended,  delayed  or  terminated  and  we  may  not  be  able  to  complete  development  of,  obtain  regulatory  approval  of  or  successfully 
commercialize our product candidates. As a result, our financial results and the commercial prospects for our product candidates would be harmed, our 
costs could increase and our ability to generate revenue could be delayed. 

If any of our relationships with these third-party CROs or others terminate, we may not be able to enter into arrangements with alternative CROs or 
other  third  parties  or  to  do  so  on  commercially  reasonable  terms.  Switching  or  adding  additional  CROs  might  require  prior  regulatory  approvals  or 
notifications and involves additional cost. Furthermore, it requires management time and focus. In addition, there is a natural transition period when a new 
CRO begins work. As a result, delays may occur, which can materially impact our ability to meet our desired development timelines. Though we carefully 
manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays 
or challenges will not have a material adverse impact on our business, financial condition and prospects. 

Because  we  rely  on  third-party  manufacturing  and  supply  vendors,  our  supply  of  research  and  development,  preclinical  and  clinical 

development materials may become limited or interrupted or may not be of satisfactory quantity or quality. 

We  rely  on  third-party  contract  manufacturers  to  manufacture  our  product  candidates  for  clinical  trials  and  preclinical  studies.  We  do  not  own 
manufacturing facilities for producing any clinical trial product supplies. There can be no assurance that our preclinical and clinical development product 
supplies will not be limited, interrupted, or of satisfactory quality or continue to be available at acceptable prices. 

The manufacturing process for a product candidate is subject to FDA and foreign regulatory authority review. Suppliers and manufacturers must 
meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply 
with regulatory standards, such as cGMPs. In the event that any of our manufacturers fail to comply with such requirements or to perform its obligations to 
us in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be 
forced to manufacture the materials ourselves, for which we currently do not have the capabilities or resources, or enter into an agreement with another 
third-party, which we may not be able to do on reasonable terms, if at all, or on a delayed basis. In some cases, the technical skills or technology required to 
manufacture  our  product  candidates  may  be  unique  or  proprietary  to  the  original  manufacturer  and  we  may  have  difficulty  transferring  such  skills  or 
technology to another third-party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or may require us 
to  obtain  a  license  from  such  manufacturer  in  order  to  have  another  third-party  manufacture  our  product  candidates.  If  we  are  required  to  change 
manufacturers  for  any  reason,  we  will  be  required  to  verify  that  the  new  manufacturer  maintains  facilities  and  procedures  that  comply  with  quality 
standards and with all applicable regulations and guidelines. The delays associated with the verification of a new manufacturer could negatively affect our 
ability to develop product candidates in a timely manner or within budget. In addition, the new manufacturer must comply with the aforementioned quality-
related regulatory requirements. 

We expect to continue to rely on third-party manufacturers if we receive regulatory approval for LTI-03, LTI-01 or any other product candidate. To 
the extent that we have existing, or enter into future, manufacturing arrangements with third parties, we will depend on these third parties to perform their 
obligations in a timely manner 

69

 
 
consistent with contractual and regulatory requirements, including those related to quality control and assurance. If we are unable to obtain or maintain 
third-party manufacturing for product candidates, or to do so on commercially reasonable terms, we may not be able to develop and commercialize our 
product candidates successfully. Our or a third-party’s failure to execute on our manufacturing requirements and comply with cGMP or other requirements 
could adversely affect our business in a number of ways, including, but not limited to: 

•

•

•

•

•

•

•

•

•

an inability to initiate or continue clinical trials of product candidates under development; 

imposition of a clinical hold; 

initiation of an Import Alert or Automatic Detection; 

delay in submitting regulatory applications, or receiving regulatory approvals, for product candidates; 

loss of the cooperation of an existing or future collaborator; 

subjecting third-party manufacturing facilities or our manufacturing facilities to additional inspections by regulatory authorities; 

requirements to cease distribution or to recall batches of our product candidates; 

increase manufacturing costs for delays and/or finding replacement manufacturers; and 

in the event of approval to market and commercialize a product candidate, an inability to meet commercial demands for our products. 

In addition, we contract with fill and finishing providers with the appropriate expertise, facilities and scale to meet our needs. Failure to maintain 
cGMP and other regulatory compliance can result in a contractor receiving sanctions by the FDA or another foreign regulatory agency, which can impact 
our  ability  to  operate  or  lead  to  delays  in  any  clinical  development  programs.  We  believe  that  our  current  fill  and  finish  contractors  are  operating  in 
accordance with cGMP and other regulatory requirements, but we can give no assurance that the FDA or other regulatory agencies will not conclude that a 
lack of compliance exists. In addition, any delay in contracting for fill and finish services, or failure of the contract manufacturer to perform the services as 
needed, may delay any clinical trials, registration and launches, which could negatively affect our business. 

The manufacture of our clinical and, if approved, commercial drug supply of LTI-01 involves a highly complex manufacturing process that is 

subject to a number of risks. 

The manufacturing process for the development of clinical, and if approved, commercial supply for LTI-01 involves a complex, multi-step process 
involving mammalian-based cell expression of the proenzyme and harvest, viral inactivation, purification and filtration of LTI-01 drug substance which is 
then lyophilized into drug product. Manufacturing any biological drug, such as LTI-01, is highly complex and is subject to a number of risks, and failure 
can  occur  at  any  stage  in  the  production  process.  If  our  manufacturing  partners  fail  to  achieve  and  maintain  high  quality  controls,  processing  and 
manufacturing  standards,  including  avoidance  of  manufacturing  errors,  defects  or  product  failures,  we  could  experience  recalls  or  withdrawals  of  our 
products,  delays  in  delivery,  cost  overruns  or  other  problems  that  would  adversely  affect  our  business.  If  our  manufacturing  partners  are  unable  to 
manufacture our products on a timely basis, at acceptable quality and costs, and in sufficient quantities, or if we experience unanticipated technological 
problems or delays in production, our business would be adversely affected. 

We depend on sole-source third-party suppliers for materials that are necessary for the conduct of preclinical studies and manufacture of our 
product  candidates  for  clinical  trials,  and  the  loss  of  these  third-party  suppliers  and  manufacturers  or  their  inability  to  supply  us  with  sufficient 
quantities of adequate materials, or to do so at acceptable quality levels and on a timely basis, could harm our business. 

Manufacturing  our  product  candidates  requires  many  specialty  materials  and  equipment,  some  of  which  are  manufactured  or  supplied  by  small
companies with limited resources and experience to support commercial biologics production. We currently depend on a limited number of vendors for 
certain  materials  and  equipment  used  in  the  manufacture  of  our  product  candidates.  For  example,  we  are  reliant  on  one  manufacturer  as  the  sole  drug 
substance manufacturer of LTI-01. If this sole supplier is unable to supply to us in the quantities we require, or at all, or otherwise 

70

 
 
defaults on its supply obligations to us, we may not be able to obtain alternative supplies from other suppliers on acceptable terms, in a timely manner, or at 
all.  We  also  do  not  have  long-term  supply  agreements  with  any  of  our  suppliers.  Our  current  contracts  with  certain  suppliers  may  be  canceled  or  not
extended by such suppliers and, therefore, do not afford us with protection against a reduction or interruption in supplies. Moreover, in the event any of 
these suppliers breach their contracts with us, our legal remedies associated with such a breach may be insufficient to compensate us for any damages we 
may suffer. 

In addition, we developed the cell line and manufacturing process for drug substance manufacture in collaboration with our sole manufacturer. The 
loss  of  this  contract  development  and  manufacturing  company,  or  CDMO,  or  its  failure  to  supply  us  with  material  to  support  our  clinical  development 
program on a timely basis could impair our ability to develop our product candidates or otherwise delay the development process, which could adversely 
affect our business, financial condition and results of operations. Some of our CDMO’s raw material suppliers may not have the capacity to support clinical 
trials and commercial products manufactured under cGMP or other regulatory requirements by biopharmaceutical firms or may otherwise be ill-equipped 
to support our needs. We also do not have supply contracts with many of these suppliers directly, and we or our CDMOs may not be able to obtain supply 
contracts with them on acceptable terms or at all. Accordingly, we or our CDMOs may experience delays in receiving key raw materials and equipment to 
support clinical or commercial manufacturing. 

For some of these specialty materials, we and our CDMOs rely on and may in the future rely on sole-source vendors or a limited number of vendors. 
The supply of specialty materials and equipment that are necessary to produce our product candidates could be reduced or interrupted at any time. In such 
case, identifying and engaging an alternative supplier or manufacturer could result in delay, and we may not be able to find other acceptable suppliers or 
manufacturers on acceptable terms, or at all. Switching suppliers or manufacturers may involve substantial costs and is likely to result in a delay in our 
desired clinical and commercial timelines. If we change suppliers or manufacturers for clinical or commercial production, applicable regulatory agencies 
may inspect the new vendor or require us to conduct additional studies or trials. If key suppliers or manufacturers are lost, or if the supply of the materials 
is diminished or discontinued, we may not be able to develop, manufacture and market our product candidates in a timely and competitive manner, or at all. 
An  inability  to  continue  to  source  product  from  any  of  these  suppliers,  which  could  be  due  to  a  number  of  issues,  including  regulatory  actions  or 
requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpected 
demands or quality issues, could adversely affect our ability to satisfy demand for our product candidates, which could adversely and materially affect our 
product sales and operating results or our ability to conduct preclinical and clinical trials, either of which could significantly harm our business. 

Our  existing  collaborations  and  future  collaborations  are  and  will  be  important  to  our  business.  If  we  are  unable  to  enter  into  new 

collaborations, or if these collaborations are not successful, our business could be adversely affected. 

A  part  of  our  strategy  is  to  selectively  establish  partnerships  in  indications  and  geographies  where  we  believe  partners  can  add  significant 
commercial  and/or  development  capabilities.  Further,  we  have  limited  capabilities  for  product  development  and  do  not  yet  have  any  capability  for 
commercialization. Accordingly, we have and may in the future enter into collaborations with other companies to provide us with important technologies 
and funding for our programs and technology. 

Our existing collaborations and any future collaborations we enter into may pose a number of risks, including the following: 

•

•

•

collaborators have significant discretion in determining the efforts and resources that they will apply; 

collaborators may not perform their obligations as expected; 

collaborators may not pursue development and commercialization of any product candidates that achieve regulatory approval or may elect 
not to continue or renew development or commercialization programs or license arrangements based on clinical trial results, changes in the 
collaborators’  strategic  focus  or  available  funding,  or  external  factors,  such  as  a  strategic  transaction  that  may  divert  resources  or  create 
competing priorities; 

71

 
 
•

•

•

•

•

•

•

•

•

•

•

collaborators  may  delay  clinical  trials,  provide  insufficient  funding  for  a  clinical  trial  program,  stop  a  clinical  trial  or  abandon  a  product 
candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing; 

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our products and 
product  candidates  if  the  collaborators  believe  that  the  competitive  products  are  more  likely  to  be  successfully  developed  or  can  be 
commercialized under terms that are more economically attractive than ours; 

product candidates discovered in collaboration with us may be viewed by our collaborators as competitive with their own product candidates 
or products, which may cause collaborators to cease to devote resources to the commercialization of our product candidates; 

collaborators may fail to comply with applicable regulatory requirements regarding the development, manufacture, distribution or marketing 
of a product candidate or product; 

collaborators  with  marketing  and  distribution  rights  to  one  or  more  of  our  product  candidates  that  achieve  regulatory  approval  may  not 
commit sufficient resources to the marketing and distribution of such product or products; 

collaborators may not provide us with timely and accurate information regarding development progress and activity under any future license 
agreement,  which  could  adversely  impact  our  ability  to  report  progress  to  our  investors  and  otherwise  plan  development  of  our  product 
candidates; 

disagreements  with  collaborators,  including  disagreements  over  proprietary  rights,  contract  interpretation  or  the  preferred  course  of 
development,  might  cause  delays  or  terminations  of  the  research,  development  or  commercialization  of  product  candidates,  might  lead  to 
additional responsibilities for us with respect to product candidates, or might result in litigation or arbitration, any of which would be time-
consuming and expensive; 

collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to
invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation; 

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability; 

if  a  collaborator  of  ours  is  involved  in  a  business  combination,  the  collaborator  might  deemphasize  or  terminate  the  development  or 
commercialization of any product candidate licensed to it by us; and 

collaborations may be terminated by the collaborator, and, if terminated, we could be required to raise additional capital to pursue further 
development or commercialization of the applicable product candidates. 

If  our  existing  collaborations  and  any  future  collaborations  we  enter  into  do  not  result  in  the  successful  research,  development  and 
commercialization of product candidates or if one of our collaborators terminates its agreement with us, we may not receive any future research funding or 
milestone or royalty payments under such collaboration. All of the risks relating to product development, regulatory approval and commercialization also 
apply to the activities of any therapeutic collaborators. 

Additionally, if one of our existing or future collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators 

and our perception in the business and financial communities could be adversely affected. 

We face significant competition in seeking appropriate collaborators for our product candidates, and the negotiation process is time-consuming and 
complex. In order for us to successfully establish a collaboration for one or more of our product candidates, potential collaborators must view these product 
candidates as economically valuable in markets they determine to be attractive in light of the terms that we are seeking and other available products for 
licensing  by  other  companies.  Collaborations  are  complex  and  time-consuming  to  negotiate  and  document.  In  addition,  there  have  been  a  significant 
number of recent business combinations among large biopharmaceutical 

72

 
 
companies  that  have  resulted  in  a  reduced  number  of  potential  future  collaborators.  Our  ability  to  reach  a  definitive  agreement  for  a  collaboration  will 
depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and 
the  proposed  collaborator’s  evaluation  of  a  number  of  factors.  If  we  are  unable  to  reach  agreements  with  suitable  collaborators  on  a  timely  basis,  on 
acceptable terms, or at all, we may have to curtail the development of a product candidate, reduce or delay its development program or one or more of our 
other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures 
and  undertake  development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  increase  our  expenditures  to  fund  development  or 
commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable 
terms,  or  at  all.  If  we  fail  to  enter  into  future  collaborations  or  do  not  have  sufficient  funds  or  expertise  to  undertake  the  necessary  development  and 
commercialization activities, we may not be able to further develop our product candidates, bring them to market and generate revenue from sales of drugs 
or continue to develop our technology, and our business may be materially and adversely affected. Even if we are successful in our efforts to establish new 
strategic collaborations, the terms that we agree upon may not be favorable to us, and we may not be able to maintain such strategic collaborations if, for 
example, development or approval of a product candidate is delayed or sales of an approved product are disappointing. Any delay in entering into new 
strategic  collaboration  agreements  related  to  our  product  candidates  could  delay  the  development  and  commercialization  of  our  product  candidates  and 
reduce their competitiveness even if they reach the market. 

We  have  entered  into  a  collaboration  agreement  with  Taiho  for  the  development  of  LTI-01  and  may  in  the  future  seek  to  enter  into 
collaborations with third parties for the development and commercialization of other product candidates. If we fail to enter into such collaborations, or 
our collaborations are not successful, we may be unable to continue development of such product candidates, we would not receive any contemplated 
milestone payments or royalties, and we could fail to capitalize on the market potential of such product candidates. 

In November 2020, Lung entered into a license and collaboration agreement with Taiho for the development and commercialization of our clinical 
product candidate, LTI-01. In the first quarter of 2021, Lung received an up-front license payment of $5.0 million for the exclusive license to develop and 
commercialize LTI-01 in Japan. 

Pursuant  to  the  Taiho  Agreement,  we  are  eligible  to  receive  a  milestone  payment,  transfer  supply  payments  for  manufacture  of  clinical  and 
commercial  supplies  of  LTI-01  and  royalties  on  annual  nets  sales  of  LTI-01.  If  we  are  unable  to  successfully  advance  the  development  of  our  product 
candidates  or  achieve  milestones,  including  pursuant  to  the  Taiho  Agreement,  we  will  not  receive  any  revenue  and  cash  resources  from  milestone  and 
royalty payments under our collaboration agreements. 

In  addition,  to  the  extent  that  any  of  our  existing  or  future  collaborators  were  to  terminate  a  collaboration  agreement,  we  may  be  forced  to 
independently develop these product candidates, including funding preclinical or clinical trials, assuming marketing and distribution costs and defending 
intellectual property rights, or, in certain instances, abandon product candidates altogether, any of which could result in a change to our business plan and a 
material and adverse effect on our business, financial condition, results of operations and prospects. 

If we decide to seek to establish collaborations, but are not able to establish those collaborations, we may have to alter our development and 

commercialization plans. 

Our development of our product candidates and the potential commercialization of our product candidates will require substantial additional cash to 
fund expenses. We may seek to selectively form collaborations to expand our capabilities, potentially accelerate research and development activities and 
provide for commercialization activities by third parties. 

We  would  face  significant  competition  in  seeking  appropriate  collaborators.  Whether  we  reach  a  definitive  agreement  for  a  collaboration  will 
depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and 
the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval 
by  the  FDA  or  comparable  foreign  regulatory  authorities,  the  potential  market  for  the  subject  product  candidate,  the  costs  and  complexities  of 
manufacturing  and  delivering  such  product  candidate  to  patients,  the  potential  of  competing  drugs,  the  existence  of  uncertainty  with  respect  to  our 
ownership of intellectual property, which can exist if there is a 

73

 
 
challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The potential collaborator may 
also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration 
could be more attractive than the one with us for our product candidate. 

We  may  also  be  restricted  under  then-existing  collaboration  agreements  from  entering  into  future  agreements  on  certain  terms  with  potential 

collaborators. 

Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business 

combinations among large pharmaceutical companies that have resulted in a reduced number of potential future collaborators. 

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all, if and when we seek to enter into collaborations. If 
we are unable to do so, we may have to curtail the development of a product candidate, reduce or delay its development program or one or more of our 
other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures 
and  undertake  development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  increase  our  expenditures  to  fund  development  or 
commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms, or at all. If we do 
not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate revenue from sales of drugs. 

Risks Related to Our Intellectual Property 

Our  success  depends  in  part  on  our  ability  to  protect  our  intellectual  property.  It  is  difficult  and  costly  to  protect  our  proprietary  rights  and 

technology, and we may not be able to ensure their protection. 

Our business will depend in large part on obtaining and maintaining patent, trademark and trade secret protection of our proprietary technologies 
and our product candidates, their respective components, synthetic intermediates, formulations, combination therapies, methods used to manufacture them 
and methods of treatment, as well as successfully defending these patents against third-party challenges. Our ability to stop unauthorized third parties from 
making,  using,  selling,  offering  to  sell  or  importing  our  product  candidates  is  dependent  upon  the  extent  to  which  we  have  rights  under  valid  and 
enforceable  patents  that  cover  these  activities  and  whether  a  court  would  issue  an  injunctive  remedy.  If  we  are  unable  to  secure  and  maintain  patent 
protection  for  any  product  or  technology  we  develop,  or  if  the  scope  of  the  patent  protection  secured  is  not  sufficiently  broad,  our  competitors  could 
develop and commercialize products and technology similar or identical to ours, and our ability to commercialize any product candidates we may develop 
may be adversely affected. 

The patenting process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications 
at a reasonable cost or in a timely manner. In addition, we may not pursue, obtain, or maintain patent protection in all relevant markets. It is also possible 
that we will fail to identify patentable aspects of our research and development output before it is too late to obtain patent protection. Moreover, in some 
circumstances,  we  may  not  have  the  right  to  control  the  preparation,  filing  and  prosecution  of  patent  applications,  or  to  maintain  the  patents,  covering 
technology that we license from or license to third parties and are reliant on our licensors or licensees. 

The strength of patents in the biotechnology and biopharmaceutical field involves complex legal and scientific questions and can be uncertain. The 
patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates or uses thereof in the U.S. or 
in other foreign countries. Even if the patents do successfully issue, third parties may challenge the validity, enforceability or scope thereof, which may 
result in such patents being narrowed, invalidated or held unenforceable. Furthermore, even if they are unchallenged, our patents and patent applications 
may not adequately protect our technology, including our product candidates, or prevent others from designing around our claims. If the breadth or strength 
of  protection  provided  by  the  patent  applications  we  hold  with  respect  to  our  product  candidates  is  threatened,  it  could  dissuade  companies  from 
collaborating with us to develop, and threaten our ability to commercialize, our product candidates. Further, if we encounter delays in our clinical trials, the 
period of time during which we could market our product candidates under patent protection would be reduced. 

74

 
 
We cannot be certain that we were the first to file any patent application related to our technology, including our product candidates, and, if we were 

not, we may be precluded from obtaining patent protection for our technology, including our product candidates. 

We cannot be certain that we are the first to invent the inventions covered by pending patent applications and, if we are not, we may be subject to 
priority disputes. Furthermore, for U.S. applications in which all claims are entitled to a priority date before March 16, 2013, an interference proceeding 
can be provoked by a third-party or instituted by the U.S. Patent and Trademark Office, or USPTO, to determine who was the first to invent any of the 
subject matter covered by the patent claims of our applications. Similarly, for U.S. applications in which at least one claim is not entitled to a priority date 
before  March  16,  2013,  derivation  proceedings  can  be  instituted  to  determine  whether  the  subject  matter  of  a  patent  claim  was  derived  from  a  prior 
inventor’s disclosure. 

We may be required to disclaim part or all of the term of certain patents or all of the term of certain patent applications. There may be prior art of 
which we are not aware that may affect the validity or enforceability of a patent or patent application claim. There also may be prior art of which we are 
aware, but which we do not believe affects the validity or enforceability of a claim, which may, nonetheless, ultimately be found to affect the validity or 
enforceability of a claim. No assurance can be given that if challenged, our patents would be declared by a court to be valid or enforceable or that even if 
found valid and enforceable, would adequately protect our product candidates, or would be found by a court to be infringed by a competitor’s technology or 
product. We may analyze patents or patent applications of our competitors that we believe are relevant to our activities and consider that we are free to 
operate in relation to our product candidates, but our competitors may achieve issued claims, including in patents we consider to be unrelated, which block 
our  efforts  or  may  potentially  result  in  our  product  candidates  or  our  activities  infringing  such  claims.  The  possibility  exists  that  others  will  develop 
products which have the same effect as our products on an independent basis which do not infringe our patents or other intellectual property rights or will 
design around the claims of patents that may issue that cover our products. 

Recent or future patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the 
enforcement or defense of our issued patents. Under the enacted Leahy-Smith America Invents Act, or America Invents Act, enacted in 2013, the U.S. 
moved from a “first to invent” to a “first-to-file” system. Under a “first-to-file” system, assuming the other requirements for patentability are met, the first 
inventor to file a patent application generally will be entitled to a patent on the invention regardless of whether another inventor had made the invention 
earlier.  The  America  Invents  Act  includes  a  number  of  other  significant  changes  to  U.S.  patent  law,  including  provisions  that  affect  the  way  patent 
applications  are  prosecuted,  redefine  prior  art  and  establish  a  new  post-grant  review  system.  The  effects  of  these  changes  are  currently  unclear  as  the 
USPTO only recently developed new regulations and procedures in connection with the America Invents Act and many of the substantive changes to patent 
law, including the “first-to-file” provisions, only became effective in March 2013. In addition, the courts have yet to address many of these provisions and 
the applicability of the act and new regulations on specific patents discussed herein have not been determined and would need to be reviewed. However, the 
America  Invents  Act  and  its  implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  patent  applications  and  the 
enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition. 

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately 

protect our rights or permit us to gain or keep our competitive advantage. For example: 

•

•

•

•

others may be able to make or use compounds that are similar to the compositions of our product candidates but that are not covered by the 
claims of our patents or those of our licensors; 

we or our licensors, as the case may be, may fail to meet our obligations to the U.S. government in regard to any in-licensed patents and 
patent applications funded by U.S. government grants, leading to the loss of patent rights; 

we or our licensors, as the case may be, might not have been the first to file patent applications for these inventions; 

others may independently develop similar or alternative technologies or duplicate any of our technologies;

it is possible that our pending patent applications will not result in issued patents; 

it is possible that there are prior public disclosures that could invalidate our or our licensors’ patents, as the case may be, or parts of our or 
their patents; 

it is possible that others may circumvent our owned or in-licensed patents; 

it is possible that there are unpublished applications or patent applications maintained in secrecy that may later issue with claims covering our 
products or technology similar to ours; 

the laws of foreign countries may not protect our or our licensors’, as the case may be, proprietary rights to the same extent as the laws of the 
U.S.; 

the claims of our owned or in-licensed issued patents or patent applications, if and when issued, may not cover our product candidates; 

our owned or in-licensed issued patents may not provide us with any competitive advantages, may be narrowed in scope, or be held invalid or 
unenforceable as a result of legal challenges by third parties; 

the  inventors  of  our  owned  or  in-licensed  patents  or  patent  applications  may  become  involved  with  competitors,  develop  products  or 
processes  which  design  around  our  patents,  or  become  hostile  to  us  or  the  patents  or  patent  applications  on  which  they  are  named  as 
inventors; 

it is possible that our owned or in-licensed patents or patent applications omit individual(s) that should be listed as inventor(s) or include 
individual(s) that should not be listed as inventor(s), which may cause these patents or patents issuing from these patent applications to be 
held invalid or unenforceable; 

we have engaged in scientific collaborations in the past and will continue to do so in the future. Such collaborators may develop adjacent or 
competing products to ours that are outside the scope of our patents; 

we may not develop additional proprietary technologies for which we can obtain patent protection; 

it is possible that product candidates or diagnostic tests we develop may be covered by third parties’ patents or other exclusive rights; or 

the patents of others may have an adverse effect on our business. 

We  are  currently  party  to  license  or  other  collaboration  agreements  that  impose  certain  obligations  on  us,  and  we  may  enter  into  additional 
license or collaboration agreements in the future. If we fail to comply with our obligations under such present or future agreements with third parties, 
we could lose license rights that may be important to our business. 

In connection with our efforts to expand our pipeline of product candidates, we may enter into certain licenses or other collaboration agreements in 
the  future  pertaining  to  the  in-license  of  rights  to  additional  candidates.  Such  agreements  may  impose  various  diligence,  milestone  payment,  royalty, 
insurance or other obligations on us. If we fail to comply with these obligations, our licensor or collaboration partners may have the right to terminate the 
relevant agreement, in which event we would not be able to develop or market the products covered by such licensed intellectual property. Our existing 
licensing agreements with UTHSCT, the University of Texas at Austin, the Medical University of South Carolina, and Vivarta Therapeutics, LLC contain 
diligence obligations to maintain each license agreement. 

Moreover, disputes may arise regarding intellectual property subject to a licensing agreement, including, but not limited to: 

•

•

•

the scope of rights granted under the license agreement and other interpretation-related issues; 

the extent to which our product candidates, technology and processes infringe on intellectual property of the licensor that is not subject to the 
licensing agreement; 

the sublicensing of patent and other rights under our collaborative development relationships; 

76

 
 
•

•

•

our diligence obligations under the license agreement and what activities satisfy those diligence obligations; 

the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors 
and us and our partners; and 

the priority of invention of patented technology. 

In  addition,  the  agreements  under  which  we  currently  license  intellectual  property  or  technology  from  third  parties  are  complex,  and  certain 
provisions  in  such  agreements  may  be  susceptible  to  multiple  interpretations.  The  resolution  of  any  contract  interpretation  disagreement  that  may  arise 
could  narrow  what  we  believe  to  be  the  scope  of  our  rights  to  the  relevant  intellectual  property  or  technology  or  increase  what  we  believe  to  be  our 
financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results 
of operations and prospects. Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current 
licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates, 
which could have a material adverse effect on our business, financial conditions, results of operations and prospects. 

In addition, we may have limited control over the maintenance and prosecution of these in-licensed patents and patent applications, or any other 
intellectual property that may be related to our in-licensed intellectual property. For example, our limited control over the prosecution of these in-licensed 
patents  and  patent  applications,  or  any  other  intellectual  property  that  may  be  related  to  our  in-licensed  intellectual  property  may  allow  the  licensors  to
pursue additional patent applications with limited input from us. Result in the licensor to pursue filing and prosecuting patent applications or obtaining 
patents without our knowledge or agreement. Such conduct by the licensor could have a material adverse effect on our business. We cannot also be certain 
that such activities by any future licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and 
enforceable  patents  and  other  intellectual  property  rights.  We  have  limited  control  over  the  manner  in  which  our  licensors  initiate  an  infringement 
proceeding against a third-party infringer of the intellectual property rights or defend certain of the intellectual property that is licensed to us. It is possible 
that the licensors’ infringement proceeding or defense activities may be less vigorous than had we conducted them ourselves. 

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and 

unsuccessful. 

Competitors  may  infringe  our  patents  or  the  patents  of  our  current  or  future  licensors.  To  counter  infringement  or  unauthorized  use,  we  may  be 

required to file infringement claims, which can be expensive and time-consuming. 

In addition, in an infringement proceeding, a court may decide that one or more of our patents is not valid or is unenforceable or may refuse to stop 
the other party from using the technology at issue on the grounds that our patents do not cover the technology in question or for other reasons. An adverse 
result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly 
and could put our patent applications at risk of not issuing. Defense of these claims, regardless of their merit, would involve substantial litigation expense 
and would be a substantial diversion of employee resources from our business. 

We may choose to challenge the patentability of claims in a third-party’s U.S. patent by requesting that the USPTO review the patent claims in an 
ex-parte  re-examination,  inter  partes  review  or  post-grant  review  proceedings.  These  proceedings  are  expensive  and  may  consume  our  time  or  other 
resources.  We  may  choose  to  challenge  a  third-party’s  patent  in  patent  opposition  proceedings  in  the  European  Patent  Office,  or  EPO,  or  other  foreign 
patent office. The costs of these opposition proceedings could be substantial and may consume our time or other resources. If we fail to obtain a favorable 
result at the USPTO, EPO or other patent office then we may be exposed to litigation by a third-party alleging that the patent may be infringed by our 
product candidates or proprietary technologies. 

In addition, because some patent applications in the U.S. may be maintained in secrecy until the patents are issued, patent applications in the U.S. 
and many foreign jurisdictions are typically not published until 18 months after filing, and publications in the scientific literature often lag behind actual 
discoveries, we cannot be certain that others have not filed patent applications for technology covered by our owned and in-licensed issued patents or our 
pending 

77

 
 
applications, or that we or, if applicable, a licensor were the first to invent the technology. Our competitors may have filed, and may in the future file, patent 
applications covering our products or technology similar to ours. Any such patent application may have priority over our owned and in-licensed patent 
applications  or  patents,  which  could  require  us  to  obtain  rights  to  issued  patents  covering  such  technologies.  If  another  party  has  filed  a  U.S.  patent 
application on inventions similar to those owned by or in-licensed to us, we or, in the case of in-licensed technology, the licensor may have to participate in 
an interference or derivation proceeding declared by the USPTO to determine priority of invention in the U.S. If we or one of our licensors is a party to an 
interference or derivation proceeding involving a U.S. patent application on inventions owned by or in-licensed to us, we may incur substantial costs, divert 
management’s time, and expend other resources, even if we are successful. 

Interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to determine the 
priority  of  inventions  with  respect  to  our  patents  or  patent  applications  or  those  of  our  licensors.  An  unfavorable  outcome  could  result  in  a  loss  of  our 
current patent rights and could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business 
could be harmed if the prevailing party does not offer us a license on commercially reasonable terms or at all, or if a non-exclusive license is offered and 
our competitors gain access to the same technology. Litigation or interference proceedings may result in a decision adverse to our interests and, even if we 
are  successful,  may  result  in  substantial  costs  and  distract  our  management  and  other  employees.  We  may  not  be  able  to  prevent,  alone  or  with  our 
licensors, misappropriation of our trade secrets or confidential information, particularly in countries where the laws may not protect those rights as fully as 
in the U.S. 

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of 
our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the 
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could 
have a substantial adverse effect on the price of our common stock. 

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed. 

In addition to patent protection, we rely heavily upon know-how and trade secret protection, as well as non-disclosure agreements and invention 
assignment agreements with our employees, consultants and third parties, to protect our confidential and proprietary information, especially where we do 
not believe patent protection is appropriate or obtainable. In addition to contractual measures, we try to protect the confidential nature of our proprietary 
information using physical and technological security measures. Such measures may not, for example, in the case of misappropriation of a trade secret by 
an employee or third-party with authorized access, provide adequate protection for our proprietary information. Our security measures may not prevent an 
employee or consultant from misappropriating our trade secrets and providing them to a competitor, and recourse we take against such misconduct may not 
provide an adequate remedy to protect our interests fully. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret can be difficult, 
expensive and time-consuming, and the outcome is unpredictable. In addition, trade secrets may be independently developed by others in a manner that 
could prevent legal recourse by us. Because we expect to rely on third parties in the development and manufacture of our product candidates, we must, at 
times,  share  trade  secrets  with  them.  If  any  of  our  confidential  or  proprietary  information,  such  as  our  trade  secrets,  were  to  be  disclosed  or 
misappropriated, or if any such information was independently developed by a competitor, our competitive position could be harmed. 

In addition, courts outside the U.S. are sometimes less willing to protect trade secrets. If we choose to go to court to stop a third-party from using 
any of our trade secrets, we may incur substantial costs. These lawsuits may consume our time and other resources even if we are successful. Although we 
take steps to protect our proprietary information and trade secrets, including through contractual means with our employees and consultants, third parties
may independently develop substantially equivalent proprietary information and techniques, or otherwise gain access to our trade secrets or disclose our 
technology. 

Thus,  we  may  not  be  able  to  meaningfully  protect  our  trade  secrets.  It  is  our  policy  to  require  our  employees,  consultants,  outside  scientific 
collaborators,  sponsored  researchers  and  other  advisors  to  execute  confidentiality  agreements  upon  the  commencement  of  employment  or  consulting 
relationships with us. These agreements provide 

78

 
 
that all confidential information concerning our business or financial affairs developed or made known to the individual or entity during the course of the 
party’s  relationship  with  us  is  to  be  kept  confidential  and  not  disclosed  to  third  parties  except  in  specific  circumstances.  In  the  case  of  employees,  the 
agreements provide that all inventions conceived by the individual, and which are related to our current or planned business or research and development or 
made during normal working hours, on our premises or using our equipment or proprietary information, are our exclusive property. In addition, we take 
other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by 
third parties. 

Third-party claims of intellectual property infringement may prevent or delay our product discovery and development efforts. 

Our  commercial  success  depends  in  part  on  our  ability  to  develop,  manufacture,  market  and  sell  our  product  candidates  and  use  our  proprietary 
technologies without infringing the proprietary rights of third parties. There is a substantial amount of litigation involving patents and other intellectual 
property rights in the biotechnology and biopharmaceutical industries, as well as administrative proceedings for challenging patents, including interference, 
derivation, inter partes review, post grant review and reexamination proceedings before the USPTO or oppositions and other comparable proceedings in 
foreign jurisdictions. We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights alleging 
that  our  product  candidates  and/or  proprietary  technologies  infringe  their  intellectual  property  rights.  Numerous  U.S.  and  foreign  issued  patents  and 
pending  patent  applications,  which  are  owned  by  third  parties,  exist  in  the  fields  in  which  we  are  developing  our  product  candidates,  and  further 
applications in the fields could continue to be filed. For example, even if we were the first to file a patent application related to our technology, we cannot 
be certain that a third-party is or will be filing and prosecuting patent applications related to our technology or related to our field, which could have a 
material adverse effect on our business. As the biotechnology and biopharmaceutical industries expand and more patents are issued, the risk increases that 
our  product  candidates  may  give  rise  to  claims  of  infringement  of  the  patent  rights  of  others.  Moreover,  it  is  not  always  clear  to  industry  participants, 
including us, which patents cover various types of drugs, products or their methods of use or manufacture. Thus, because of the large number of patents 
issued  and  patent  applications  filed  in  our  fields,  there  may  be  a  risk  that  third  parties  may  allege  they  have  patent  rights  encompassing  our  product 
candidates, technologies or methods. 

If a third-party claims that we infringe its intellectual property rights, we may face a number of issues, including, but not limited to:

•

•

•

•

•

infringement  and  other  intellectual  property  claims  which,  regardless  of  merit,  may  be  expensive  and  time-consuming  to  litigate  and  may 
divert our management’s attention from our core business; 

substantial damages for infringement, which we may have to pay if a court decides that the product candidate or technology at issue infringes 
on or violates the third-party’s rights and if the court finds that the infringement was willful, we could be ordered to pay treble damages and 
the patent owner’s attorneys’ fees; 

a  court  prohibiting  us  from  developing,  manufacturing,  marketing  or  selling  our  product  candidates,  or  from  using  our  proprietary 
technologies, unless the third-party licenses its product rights to us, which it is not required to do; 

if  a  license  is  available  from  a  third-party,  we  may  have  to  pay  substantial  royalties,  upfront  fees  and  other  amounts,  and/or  grant  cross-
licenses  to  intellectual  property  rights  for  our  products  and  any  license  that  is  available  may  be  non-exclusive,  which  could  result  in  our 
competitors gaining access to the same intellectual property; and 

redesigning  our  product  candidates  or  processes  so  they  do  not  infringe,  which  may  not  be  possible  or  may  require  substantial  monetary 
expenditures and time. 

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially 
greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our 
ability  to  raise  the  funds  necessary  to  continue  our  operations  or  could  otherwise  have  a  material  adverse  effect  on  our  business,  results  of  operations, 
financial condition and prospects. Furthermore, because of the substantial amount of discovery required in connection with 

79

 
 
intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. 

We may not be able to protect our intellectual property rights with patents throughout the world. 

Filing, prosecuting and defending patents on our product candidates throughout the world would be prohibitively expensive. Competitors may use 
our technology in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing 
products to territories where we have patent protection but where enforcement is not as strong as in the U.S. These products may compete with our product 
candidates  in  jurisdictions  where  we  do  not  have  any  issued  patents  and  our  patent  claims  or  other  intellectual  property  rights  may  not  be  effective  or 
sufficient to prevent them from so competing. Many companies have encountered significant problems in protecting and defending intellectual property 
rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and 
other intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of our 
patents  or  marketing  of  competing  products  against  third  parties  in  violation  of  our  proprietary  rights  generally.  The  initiation  of  proceedings  by  third 
parties to challenge the scope or validity of our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from 
other aspects of our business. 

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other 
requirements  imposed  by  governmental  patent  agencies,  and  our  patent  protection  could  be  reduced  or  eliminated  for  non-compliance  with  these 
requirements. 

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the 
patent.  The  USPTO  and  various  foreign  governmental  patent  agencies  require  compliance  with  a  number  of  procedural,  documentary,  fee  payment  and 
other provisions during the patent application process and following the issuance of a patent. While an inadvertent lapse can in many cases be cured by 
payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or 
lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could 
result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time 
limits, non-payment of fees and failure to properly legalize and submit formal documents. In certain circumstances, even inadvertent noncompliance events 
may  permanently  and  irrevocably  jeopardize  patent  rights.  In  such  an  event,  our  competitors  might  be  able  to  enter  the  market,  which  would  have  a 
material adverse effect on our business. 

Our collaborators may assert ownership or commercial rights to inventions they develop from research we support or that we develop from our

use of samples or other materials, which they provide to us, or otherwise arising from the collaboration. 

We collaborate with several institutions, universities, medical centers, physicians and researchers in scientific matters and expect to continue to enter 
into additional collaboration agreements. In certain cases, we do not have written agreements with these collaborators, or the written agreements we have 
do not cover intellectual property rights. If we cannot successfully negotiate sufficient ownership and commercial rights to any inventions that result from 
our  use  of  a  third-party  collaborator’s  materials,  or  if  disputes  arise  with  respect  to  the  intellectual  property  developed  with  the  use  of  a  collaborator’s 
samples,  or  data  developed  in  a  collaborator’s  study,  we  may  be  limited  in  our  ability  to  capitalize  on  the  market  potential  of  these  inventions  or 
developments. 

Third parties may assert that we are employing their proprietary technology without authorization. 

There  may  be  third-party  patents  of  which  we  are  currently  unaware  with  claims  to  compositions  of  matter,  materials,  formulations,  methods  of 
manufacture  or  methods  for  treatment  that  encompass  the  composition,  use  or  manufacture  of  our  product  candidates.  There  may  be  currently  pending 
patent applications of which we are currently unaware which may later result in issued patents that our product candidates or their use or manufacture may 
infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party 
patent were held by a court of competent jurisdiction to cover our product candidates, intermediates used in the manufacture of our product candidates or 
our materials generally, aspects of our formulations 

80

 
 
or methods of use, the holders of any such patent may be able to block our ability to develop and commercialize the product candidate unless we obtained a 
license  or  until  such  patent  expires  or  is  finally  determined  to  be  held  invalid  or  unenforceable.  In  either  case,  such  a  license  may  not  be  available  on 
commercially reasonable terms or at all. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, or at all, 
our ability to commercialize our product candidates may be impaired or delayed, which could in turn significantly harm our business. Even if we obtain a 
license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, if the breadth or strength of 
protection provided by our patents and patent applications is threatened, it could dissuade parties making claims against us may seek and obtain injunctive 
or other equitable relief, which could effectively block our ability to further develop and commercialize our product candidates. Defense of these claims, 
regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the 
event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful 
infringement,  obtain  one  or  more  licenses  from  third  parties,  pay  royalties  or  redesign  our  infringing  products,  which  may  be  impossible  or  require 
substantial  time  and  monetary  expenditure.  We  cannot  predict  whether  any  such  license  would  be  available  at  all  or  whether  it  would  be  available  on 
commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or 
allow commercialization of our product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that 
event, we would be unable to further develop and commercialize our product candidates, which could harm our business significantly. 

Third parties may assert that our employees or consultants have wrongfully used or disclosed confidential information or misappropriated trade 

secrets. 

As is common in the biotechnology and biopharmaceutical industries, we employ individuals who were previously employed at universities or other 
biotechnology or biopharmaceutical companies, including our competitors or potential competitors. Although no claims against us are currently pending, 
and although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we 
may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed intellectual 
property, including trade secrets or other proprietary information, of a former employer or other third parties. Litigation may be necessary to defend against 
these  claims.  If  we  fail  in  defending  any  such  claims,  in  addition  to  paying  monetary  damages,  we  may  lose  valuable  intellectual  property  rights  or 
personnel.  Even  if  we  are  successful  in  defending  against  such  claims,  litigation  or  other  legal  proceedings  relating  to  intellectual  property  claims  may 
cause  us  to  incur  significant  expenses  and  could  distract  our  technical  and  management  personnel  from  their  normal  responsibilities.  In  addition,  there 
could be public announcements of the results of hearings, motions or other interim proceedings or developments, and, if securities analysts or investors 
perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. This type of litigation or proceeding could 
substantially  increase  our  operating  losses  and  reduce  our  resources  available  for  development  activities.  We  may  not  have  sufficient  financial  or  other 
resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings 
more effectively than we can because of their substantially greater financial resources. Uncertainties resulting from the initiation and continuation of patent 
litigation or other intellectual property related proceedings could adversely affect our ability to compete in the marketplace. 

Any current or future patents, if issued, covering our product candidates could be found invalid or unenforceable if challenged in court or the 

USPTO. 

If we or one of our licensors initiate legal proceedings against a third-party to enforce a patent covering one of our product candidates, the defendant 
could counterclaim that the patent covering our product candidate, as applicable, is invalid and/or unenforceable. In patent litigation in the U.S., defendant 
counterclaims alleging invalidity and/or unenforceability are commonplace, and there are numerous grounds upon which a third-party can assert invalidity 
or unenforceability of a patent. Third parties may also raise similar claims before administrative bodies in the U.S. or abroad, even outside the context of 
litigation.  Such  mechanisms  include  re-examination,  inter  partes  review,  post  grant  review  and  equivalent  proceedings  in  foreign  jurisdictions  (e.g., 
opposition proceedings). Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover our product 
candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, 
we cannot be certain that there is no invalidating prior art, of which we, our patent counsel and 

81

 
 
the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, or if we are 
otherwise unable to adequately protect our rights, we would lose at least part, and perhaps all, of the patent protection on our product candidates. Such a 
loss  of  patent  protection  could  have  a  material  adverse  impact  on  our  business  and  our  ability  to  commercialize  or  license  our  technology  and  product 
candidates. 

Changes in patent law in the U.S. and in foreign jurisdictions could diminish the value of patents in general, thereby impairing our ability to 

protect our products. 

Changes  in  either  the  patent  laws  or  interpretation  of  the  patent  laws  in  the  U.S.  could  increase  the  uncertainties  and  costs  surrounding  the 
prosecution of patent applications and the enforcement or defense of issued patents. Assuming that other requirements for patentability are met, prior to 
March 16, 2013, in the U.S., the first to invent the claimed invention was entitled to the patent, while outside the U.S., the first to file a patent application 
was entitled to the patent. On March 16, 2013, under America Invents Act, the U.S. transitioned to a first inventor to file system in which, assuming that 
other requirements for patentability are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether 
a third party was the first to invent the claimed invention. A third party that files a patent application in the USPTO on or after March 16, 2013, but before 
us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This will 
require us to be cognizant of the time from invention to filing of a patent application. Since patent applications in the U.S. and most other countries are 
confidential  for  a  period  of  time  after  filing  or  until  issuance,  we  cannot  be  certain  that  we  or  our  licensors  were  the  first  to  either  (i)  file  any  patent 
application related to our product candidates or (ii) invent any of the inventions claimed in our or our licensor’s patents or patent applications. 

The  America  Invents  Act  also  includes  a  number  of  significant  changes  that  affect  the  way  patent  applications  will  be  prosecuted  and  also  may 
affect patent litigation. These include allowing third party submission of prior art to the USPTO during patent prosecution and additional procedures to 
attack the validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. 
Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal courts necessary to invalidate a patent 
claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same 
evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO 
procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action. 
Therefore,  the  America  Invents  Act  and  its  implementation  could  increase  the  uncertainties  and  costs  surrounding  the  prosecution  of  our  owned  or  in-
licensed patent applications and the enforcement or defense of our owned or in-licensed issued patents, all of which could have a material adverse effect on 
our business, financial condition, results of operations, and prospects. 

In addition, the patent positions of companies in the development and commercialization of biopharmaceuticals are particularly uncertain. Recent 
U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in 
certain situations. This combination of events has created uncertainty with respect to the validity and enforceability of patents, once obtained. Depending 
on future actions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways 
that could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future. 

We have limited foreign intellectual property rights and may not be able to protect our intellectual property rights throughout the world. 

We  have  limited  intellectual  property  rights  outside  the  U.S.  Filing,  prosecuting  and  defending  patents  on  product  candidates  in  all  countries 
throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the U.S. can be less extensive than 
those in the U.S. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the 
U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S., or from selling or importing 
products made using our inventions in and into the U.S. or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not 
obtained  patent  protection  to  develop  their  own  products  and,  further,  may  export  otherwise  infringing  products  to  territories  where  we  have  patent 
protection but where enforcement is not as strong as that in the U.S. These products may compete with our products in 

82

 
 
jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or sufficient to prevent 
them from competing. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal 
systems of certain countries, particularly certain developing countries, do not favor the enforcement of, and may require a compulsory license to, patents, 
trade secrets and other intellectual property protection, particularly those relating to biopharmaceutical products, which could make it difficult for us to stop 
the infringement of our patents or marketing of competing products against third parties in violation of our proprietary rights generally. The initiation of 
proceedings by third parties to challenge the scope or validity of our patent rights in foreign jurisdictions could result in substantial cost and divert our 
efforts and attention from other aspects of our business. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and 
divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent 
applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the 
damages  or  other  remedies  awarded,  if  any,  may  not  be  commercially  meaningful.  Accordingly,  our  efforts  to  enforce  our  intellectual  property  rights 
around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. 

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time. 

Patents have a limited lifespan. In the U.S., if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its 
earliest U.S. non-provisional filing date. Various extensions such as patent term adjustments and/or extensions, may be available, but the life of a patent, 
and the protection it affords, is limited. Even if patents covering our product candidates are obtained, once the patent life has expired, we may be open to 
competition from competitive products. Given the amount of time required for the development, testing and regulatory review of new product candidates, 
patents  protecting  such  candidates  might  expire  before  or  shortly  after  such  candidates  are  commercialized.  As  a  result,  our  owned  and  licensed  patent 
portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. We have a license to one 
U.S. patent from the Board of Regents of the University of Texas System directed to methods of using intrapleural single chain urokinase plasminogen 
activator,  or  scuPA,  polypeptide  for  decreasing  the  severity  of  pleural  scarring,  which  is  expected  to  expire  in  2024  without  patent  term  extension.  We 
cannot assure that once the patent life has expired, we will not face competition from competitive products. Given the limited patent life, we will be relying 
on the 12 years of data exclusivity provided under the BPCIA, as well as the complexity of the manufacturing process of LTI-01. There can be no assurance 
that BPCIA product protection will be available if LTI-01 is approved, or the company will be able to maintain the confidentiality of its trade secrets and 
know-how in its manufacturing process. 

If  we  do  not  obtain  patent  term  extension  and  data  exclusivity  for  any  product  candidates  we  may  develop,  our  business  may  be  materially 

harmed. 

Depending upon the timing, duration and specifics of any FDA marketing approval of any product candidates we may develop, one or more of our 
U.S.  patents  may  be  eligible  for  limited  patent  term  extension  under  the  Drug  Price  Competition  and  Patent  Term  Restoration  Action  of  1984  Hatch-
Waxman  Amendments,  or  the  Hatch-Waxman  Amendments.  The  Hatch-Waxman  Amendments  permit  a  patent  extension  term  of  up  to  five  years  as 
compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond 
a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a method for 
using it, or a method for manufacturing it may be extended. However, we may not be granted an extension because of, for example, failing to exercise due 
diligence during the testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant 
patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less 
than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, our competitors may obtain 
approval  of  competing  products  following  our  patent  expiration,  and  our  business,  financial  condition,  results  of  operations,  and  prospects  could  be 
materially harmed. 

83

 
 
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest 

and our business may be adversely affected. 

Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We 
may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition 
by potential partners or customers in our markets of interest. If we are unable to establish name recognition based on our trademarks and trade names, we 
may not be able to compete effectively, and our business may be adversely affected. 

Risks Related to Employee Matters and Managing Growth 

We may encounter difficulties in managing our growth, which could adversely affect our operations. 

As our clinical development and commercialization plans and strategies develop, we will need to expand our managerial, clinical, regulatory, sales, 
marketing, financial, development, manufacturing and legal capabilities or contract with third parties to provide these capabilities for us. As our operations 
expand, we expect that we will need to manage additional relationships with various strategic collaborators, suppliers and other third parties. Our future 
growth would impose significant added responsibilities on members of management, including, but not limited to: 

•

•

•

identifying, recruiting, integrating, maintaining and motivating additional employees; 

managing our development and commercialization efforts effectively, including the clinical and FDA review process for LTI-03, LTI-01 and
any other product candidates, while complying with our contractual obligations to contractors and other third parties; and 

improving our operational, financial and management controls, reporting systems and procedures. 

Our ability to continue to develop and, if approved, commercialize our product candidates will depend, in part, on our ability to effectively manage 
any future growth. Our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a 
substantial amount of time to managing these growth activities. 

We  currently  rely,  and  for  the  foreseeable  future  will  continue  to  rely,  in  substantial  part  on  certain  independent  organizations,  advisors  and 
consultants to provide certain services, including contract manufacturers and companies focused on research and development activities. There can be no 
assurance that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that 
we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality, accuracy or quantity of the 
services provided is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain, or may be 
substantially delayed in obtaining, regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will 
be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all. 

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may 
not  be  able  to  successfully  implement  the  tasks  necessary  to  further  develop  and  commercialize  LTI-03,  LTI-01  or  any  other  product  candidates  and, 
accordingly, may not achieve our research, development and commercialization goals. 

We may acquire additional technology and complementary businesses in the future. Acquisitions involve many risks, any of which could materially 
harm  our  business,  including  the  diversion  of  management’s  attention  from  core  business  concerns,  failure  to  effectively  exploit  acquired  technologies, 
failure to successfully integrate the acquired business or realize expected synergies or the loss of key employees from either our business or the acquired 
businesses. 

If we lose key management personnel or consultants, or if we fail to recruit additional highly skilled personnel, our ability to develop current 
product candidates or identify and develop new product candidates will be impaired, could result in loss of markets or market share and could make us 
less competitive. 

84

 
 
Our  ability  to  compete  in  the  highly  competitive  biotechnology  and  biopharmaceutical  industries  depends  upon  our  ability  to  attract  and  retain 
highly  qualified  managerial,  scientific  and  medical  personnel  and  consultants.  We  are  highly  dependent  on  our  management,  scientific  and  medical 
personnel and consultants. The loss of the services of any of our executive officers, other key employees, and other scientific and medical advisors and 
consultants, and our inability to find suitable replacements could result in delays in product development and harm our business. Competition for skilled 
personnel in our industry is intense and may limit our ability to hire and retain highly qualified personnel on acceptable terms or at all. 

To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided stock options that vest over 
time. The value to employees of stock options that vest over time may be significantly affected by movements in our stock price that are beyond our control 
and may at any time be insufficient to counteract more lucrative offers from other companies. Despite our efforts to retain valuable employees, members of 
our management, scientific and development teams may terminate their employment with us on short notice. Our key employees are at-will employees, 
which means that any of our key employees could leave our employment at any time, with or without notice. Our success also depends on our ability to 
continue to attract, retain and motivate highly skilled junior, mid-level and senior scientific and medical personnel and consultants. 

Our internal computer systems, or those of our vendors or other contractors or consultants, may fail or suffer security breaches, which could 

result in a material disruption of our product development programs. 

Although  we  attempt  to  secure  our  systems  and  have  a  process  to  identify  and  mitigate  threats,  our  internal  computer  systems  and  those  of  our 
current  and  any  future  vendors  and  other  contractors  or  consultants  are  vulnerable  to  damage  from  computer  viruses,  ransomware  attacks  and  other 
malicious behavior, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced 
any such material system failure, accident, attack or security breach to date, if such an event were to occur and cause interruptions in our operations, it 
could  result  in  a  disruption  of  our  development  programs  and  our  business  operations,  whether  due  to  a  loss  of  our  trade  secrets  or  other  proprietary 
information, inability to access critical systems and applications, or other similar disruptions. For example, the loss of clinical trial data from future clinical 
trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any 
disruption,  attack  or  security  breach  were  to  result  in  a  loss  of,  or  damage  to,  our  data  or  applications,  or  inappropriate  disclosure  of  confidential  or 
proprietary information, we could incur costs of notification to individuals, regulators and other third parties, remediation costs, liability to our customers
or third parties and/or regulatory fines and penalties, our competitive position could be harmed, and the further development and commercialization of our 
product candidates could be delayed. 

We could be subject to risks caused by misappropriation, misuse, leakage, falsification or intentional or accidental release or loss of information 
maintained in the information systems and networks of our company and our vendors, including personal information of our employees and study subjects, 
and company and vendor confidential data. In addition, outside parties may attempt to penetrate our systems or those of our vendors or fraudulently induce 
our  personnel  or  the  personnel  of  our  vendors  to  disclose  sensitive  information  in  order  to  gain  access  to  our  data  and/or  systems.  We  may  experience 
threats to our data and systems, including malicious codes and viruses, phishing, ransomware and other cyberattack. The number and complexity of these 
threats continue to increase over time. If a material breach of, or accidental or intentional loss of data from, our information technology systems or those of 
our  vendors  occurs,  the  market  perception  of  the  effectiveness  of  our  security  measures  could  be  harmed  and  our  reputation  and  credibility  could  be 
damaged. We could be required to expend significant amounts of money and other resources to respond to an incident and repair or replace information 
systems or networks. In addition, we could be subject to regulatory actions and/or claims made by individuals and groups in private litigation involving 
privacy  issues  related  to  data  collection  and  use  practices  and  other  data  privacy  laws  and  regulations,  including  claims  for  misuse  or  inappropriate 
disclosure  of  data,  failure  to  use  reasonable  measures  to  safeguard  data,  violation  of  state  laws  protecting  the  confidentiality,  privacy  and  integrity  of 
personal  information  and  health-related  information,  as  well  as  unfair  or  deceptive  practices.  Although  we  develop  and  maintain  systems  and  controls 
designed to prevent these events from occurring, and we have a process to identify and mitigate threats, the development and maintenance of these systems, 
controls and processes is costly and requires ongoing monitoring and updating as technologies change and efforts to overcome security measures become 
increasingly sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely. As we outsource more of 
our information systems to vendors, engage in more electronic transactions with payors and patients, and rely more on cloud-based information systems, 
the related 

85

 
 
security risks will increase, and we will need to expend additional resources to protect our own technology and information systems and manage potential 
security risks associated with our vendors. In addition, there can be no assurance that our internal information technology systems or those of our third-
party vendors, or our and our vendors’ efforts to implement adequate security and control measures, will be sufficient to protect us against breakdowns, 
service disruption, data deterioration or loss in the event of a system malfunction, or prevent data from being stolen or corrupted or the company being 
subject  to  attempted  extortion  in  the  event  of  a  cyberattack  or  ransomware  attack,  security  breach,  industrial  espionage  attacks  or  insider  threat  attacks 
which could result in financial, legal, business or reputational harm. 

We or the third parties upon whom we depend may be adversely affected by natural disasters and our business continuity and disaster recovery 

plans may not adequately protect us from a serious disaster, including outbreak of disease or other natural disasters. 

Any unplanned event, such as flood, fire, explosion, extreme weather condition, medical epidemics, power shortage, telecommunication failure or 
other natural or manmade accidents or incidents that result in us being unable to fully utilize our facilities, or the manufacturing facilities of our third-party 
contract manufacturers, may have a material and adverse effect on our ability to operate our business, particularly on a daily basis, and have significant 
negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development 
of our product candidates or interruption of our business operations. Natural disasters could further disrupt our operations and have a material and adverse 
effect on our business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented us 
from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our research facilities or the manufacturing facilities 
of our third-party contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible, for us to continue our 
business for a substantial period of time. 

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations. 

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. Portions of 
our future clinical trials may be conducted outside of the U.S. and unfavorable economic conditions resulting in the weakening of the U.S. dollar would 
make those clinical trials more costly to operate. Furthermore, the most recent global financial crisis caused extreme volatility and disruptions in the capital 
and credit markets. A severe or prolonged economic downturn, including due to the impact of the COVID-19 pandemic, could result in a variety of risks to 
our  business,  including  a  reduced  ability  to  raise  additional  capital  when  needed  on  acceptable  terms,  if  at  all.  A  weak  or  declining  economy  or 
international trade disputes could also strain our suppliers, some of which are located outside of the U.S., possibly resulting in supply disruption. Any of the 
foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could 
adversely impact our business. 

Risks Related to Our Common Stock 

 If  we  fail  to  maintain  compliance  with  the  requirements  for  continued  listing  on  the  Nasdaq  Capital  Market,  our  common  stock  could  be 

delisted from trading, which would adversely affect the liquidity of our common stock. 

In  the  past  we  have  received  written  notification  from  the  Nasdaq  Stock  Market,  or  Nasdaq,  informing  us  that  we  were  not  in  compliance  with 
certain continued listing requirements of the Nasdaq Capital Market. As previously disclosed, on December 16, 2021, we received a deficiency letter from 
the Listing Qualifications Department of Nasdaq notifying us that, for the last 30 consecutive business days, the bid price for our common stock had closed 
below the minimum $1.00 per share requirement for continued inclusion on the Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(a)(2), or the 
Bid Price Rule. On June 7, 2022, we received notification from Nasdaq notifying us that we were provided an additional 180 calendar day period or until 
December 5, 2022 to regain compliance with the Bid Price Rule. 

We completed a 1-for-20 reverse stock split on our common stock on November 10, 2022. We regained compliance with the Bid Price Rule after the 

closing bid price of our common stock was above $1.00 per share for 10 

86

 
 
consecutive business days from November 11, 2022 to November 25, 2022. On November 28, 2022, we received a letter from Nasdaq notifying us that we 
had regained compliance with the Bid Price Rule and we have remained in compliance.

In addition, on January 4, 2024, we received written notice, or the Notice, from the Listing Qualifications Department of Nasdaq stating that we 
failed to hold our annual meeting of shareholders within twelve months after our fiscal year ended December 31, 2022, as required by Nasdaq Listing Rule 
5620(a), or the Annual Meeting Listing Rule. The Notice does not result in the immediate delisting of our common stock from the Nasdaq Capital Market. 

The Notice stated that we have 45 calendar days, or until February 20, 2024, to submit a plan to regain compliance with the Annual Meeting Listing 
Rule. On January 31, 2024, we submitted a plan (which conveyed our intention to hold our 2023 annual meeting of stockholders on February 28, 2024) to 
regain compliance with the Annual Meeting Listing Rule within the required time frame. On February 20, 2024, we were notified that Nasdaq had accepted 
our  plan  and  granted  us  an  extension  until  February  28,  2024  to  regain  compliance.  On  February  28,  2024,  we  held  our  2023  annual  meeting  of 
stockholders and on February 29, 2024, we received a letter from Nasdaq notifying us that we had regained compliance with the Annual Meeting Listing 
Rule and we have remained in compliance. 

Furthermore, in connection with the Lung Acquisition, we issued 19,903 shares of Series X Convertible Preferred Stock, which are convertible into 
an aggregate of 19,903,000 shares of our common stock. Nasdaq Listing Rule 5110(a) provides that a company must apply for initial listing in connection 
with a transaction whereby a company combines with a non-Nasdaq entity, resulting in a change of control of such company and potentially allowing the 
non-Nasdaq  entity  to  effectively  obtain  Nasdaq  listing.  In  determining  whether  a  change  of  control  has  occurred,  Nasdaq  considers  all  relevant  factors 
including, changes in management, board of directors, voting power, ownership and financing structure of the company. If Nasdaq does not agree with our 
determination that the Lung Acquisition and the issuance of shares of our common stock and Series X Preferred Stock pursuant to the Lung Acquisition 
Agreement did not result in a change of control, we will be in violation of Nasdaq Listing Rule 5110(a) and our common stock could be delisted from the 
Nasdaq Capital Market. 

There  can  be  no  assurance  that  we  will  continue  to  maintain  compliance  with  the  requirements  for  listing  our  common  stock  on  Nasdaq.  Any 
potential delisting of our common stock from the Nasdaq Capital Market would likely result in decreased liquidity and increased volatility for our common 
stock and would adversely affect our ability to raise additional capital or to enter into strategic transactions. Any potential delisting of our common stock 
from the Nasdaq Capital Market would also make it more difficult for our stockholders to sell our common stock in the public market. 

An active trading market for our common stock may not be sustained. 

Our shares of common stock began trading on The Nasdaq Global Market on June 29, 2017, and transferred to The Nasdaq Capital Market, effective 
December  30,  2019.  Given  the  limited  trading  history  of  our  common  stock,  there  is  a  risk  that  an  active  trading  market  for  our  shares  may  not  be 
sustained, which could put downward pressure on the market price of our common stock and thereby affect the ability of stockholders to sell their shares. 
An inactive trading market for our common stock may also impair our ability to raise capital to continue to fund our operations by selling shares and may 
impair our ability to acquire other companies or technologies by using our shares as consideration. 

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our 

stock could decline. 

The  trading  market  for  our  common  stock  relies  in  part  on  the  research  and  reports  that  industry  or  financial  analysts  publish  about  us  or  our 
business. If few analysts commence, or if analysts discontinue, coverage of us, the trading price of our stock would likely decrease. If one or more of the 
analysts covering our business downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover
our stock, we could lose visibility in the market for our stock, which in turn could cause our stock price to decline. 

The price of our stock may be volatile, and you could lose all or part of your investment. 

87

 
 
The trading price of our common stock is highly volatile and could be subject to wide fluctuations in response to various factors, some of which are

any delay in our regulatory filings for LTI-03, LTI-01 or our other product candidates and any adverse development or perceived adverse 
development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a 
“refusal to file” letter or a request for additional information; 

adverse results or delays in future clinical trials; 

our decision to initiate a clinical trial, not to initiate a clinical trial or to terminate an existing clinical trial; 

adverse regulatory decisions, including failure to receive regulatory approval of LTI-03, LTI-01 or any other product candidate;

ineffectiveness of our internal controls; 

disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection 
for our technologies; 

significant lawsuits, including patent or stockholder litigation; 

general political and economic conditions; 

the level of expenses related to our product candidates or clinical development programs; 

investors’ general perception of us and our business; and 

other events or factors, many of which are beyond our control. 

In addition, the stock market in general, and the market for biopharmaceutical companies in particular, have experienced extreme price and volume 
fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may 
negatively affect the market price of our common stock, regardless of our actual operating performance. In the past, securities class action litigation has 
often been instituted against companies following periods of volatility in the market price of a company’s securities. This type of litigation, if instituted, 
could result in substantial costs and a diversion of management’s attention and resources. 

We could be subject to securities class action litigation. 

In the past, securities class action litigation has often been brought against a company following a decline in the market price of its securities. This 
risk  is  especially  relevant  for  us  because  pharmaceutical  companies  have  experienced  significant  stock  price  volatility  in  recent  years.  If  we  face  such 
litigation, it could result in substantial costs and a diversion of management’s attention and our resources, which could harm our business. 

We  are  a  “smaller  reporting  company”  and  the  reduced  disclosure  requirements  applicable  to  smaller  reporting  companies  may  make  our 

common stock less attractive to investors. 

We  are  a  smaller  reporting  company,  and  we  will  remain  a  smaller  reporting  company  until  the  fiscal  year  following  the  determination  that  our 
voting and non-voting common stock held by non-affiliates is more than $250.0 million measured on the last business day of our second fiscal quarter, or 
our annual revenues are less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-
affiliates  is  more  than  $700.0  million  measured  on  the  last  business  day  of  our  second  fiscal  quarter.  Smaller  reporting  companies  are  able  to  provide 
simplified  executive  compensation  disclosure  and  have  certain  other  reduced  disclosure  obligations,  including,  among  other  things,  being  required  to 
provide only two years of audited financial statements and not being required to provide selected financial data, supplemental financial information or risk 
factors. 

We have elected to take advantage of certain of the reduced reporting obligations. Investors may find our common stock less attractive as a result of 
our reliance on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our 
common stock and our stock price may be more volatile. 

We have incurred and will continue to incur increased costs as a result of operating as a public company, and our management will be required 

to devote substantial time to new compliance initiatives and corporate governance practices. 

As a public company we have incurred and we will continue to incur significant legal, accounting and other expenses. The Sarbanes-Oxley Act of 
2002,  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act,  the  listing  requirements  of  The  Nasdaq  Global  Market  and  other  applicable 
securities  rules  and  regulations  impose  various  requirements  on  public  companies,  including  establishment  and  maintenance  of  effective  disclosure  and 
financial  controls  and  corporate  governance  practices.  Our  management  and  other  personnel  will  need  to  devote  a  substantial  amount  of  time  to  these 
compliance  initiatives.  Moreover,  these  rules  and  regulations  increase  our  legal  and  financial  compliance  costs,  and  make  some  activities  more  time-
consuming and costly. 

89

 
 
These  rules  and  regulations  are  often  subject  to  varying  interpretations,  in  many  cases  due  to  their  lack  of  specificity,  and,  as  a  result,  their 
application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty 
regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

Changes in tax laws or in their implementation or interpretation may adversely affect our business and financial condition. 

Changes in tax law may adversely affect our business or financial condition. The TCJA, as amended by the CARES Act, significantly reformed the 
U.S.  Internal  Revenue  Code  of  1986,  as  amended,  or  the  Code.  The  TCJA,  among  other  things,  contained  significant  changes  to  corporate  taxation, 
including a reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21% and, the limitation of the deduction for net operating
losses to 80% of current year taxable income and the elimination of loss carrybacks for losses arising in taxable years beginning after December 31, 2017 
(though any such net operating losses may be carried forward indefinitely). The CARES Act delayed the 80% net operating loss limitation and allowed 
losses  to  be  carried  back  five  years  for  net  operating  losses  generated  in  years  beginning  after  December  31,  2017  and  before  December  1,  2021.  In 
addition,  beginning  in  2022,  the  TCJA  eliminated  the  option  to  deduct  research  and  development  expenditures  currently  and  requires  corporations  to 
capitalize and amortize them over five years. 

In addition to the CARES Act, as part of Congress’ response to the COVID-19 pandemic, economic relief legislation has been enacted in 2020 and
2021 containing tax provisions. The Inflation Reduction Act, or IRA, was also signed into law in August 2022. The IRA introduced new tax provisions, 
including a 1% excise tax imposed on certain stock repurchases by publicly traded corporations. The 1% excise tax generally applies to any acquisition by 
the publicly traded corporation (or certain of its affiliates) of stock of the publicly traded corporation in exchange for money or other property (other than 
stock  of  the  corporation  itself),  subject  to  a  de  minimis  exception.  Thus,  the  excise  tax  could  apply  to  certain  transactions  that  are  not  traditional  stock 
repurchases. 

Regulatory  guidance  under  the  TCJA,  the  IRA,  and  such  additional  legislation  is  and  continues  to  be  forthcoming,  and  such  guidance  could 
ultimately increase or lessen impact of these laws on our business and financial condition. In addition, it is uncertain if and to what extent various states 
will conform to the TCJA, the IRA, and additional tax legislation. 

We  might  not  be  able  to  utilize  a  significant  portion  of  our  net  operating  loss  carryforwards  and  research  and  development  tax  credit 

carryforwards. 

As of December 31, 2023, we had federal net operating loss carryforwards of $56.5 million, of which $2.9 million will, if not utilized, begin to 
expire in 2036. As of December 31, 2023, we had state net operating carryforwards of $8.2 million, which will, if not utilized, begin to expire in 2043. Our 
federal research and development tax credit carryforwards of $1.1 million will, if not utilized, begin to expire in 2035. We also have federal orphan drug tax
credit  carryforwards  of  $6.7  million  which  begin  to  expire  in  2039.  These  net  operating  loss  and  tax  credit  carryforwards  could  expire  unused  and  be 
unavailable to offset future income tax liabilities. We have a history of cumulative losses and anticipate that we will continue to incur significant losses in 
the foreseeable future; thus, we do not know whether or when we will generate taxable income necessary to utilize our net operating losses or research and 
development tax credit carryforwards. 

We have a history of cumulative losses and anticipate that we will continue to incur significant losses in the foreseeable future; thus, we do not know 

whether or when we will generate taxable income necessary to utilize our net operating losses or research and development tax credit carryforwards. 

In addition, as described above in “Changes in tax laws or in their implementation or interpretation may adversely affect our business and financial 
condition,” the TCJA, as amended by the CARES Act, includes changes to U.S. federal tax rates and the rules governing net operating loss carryforwards 
that may significantly impact our ability to utilize our net operating losses to offset taxable income in the future. 

90

 
 
Furthermore, under Section 382 of the Code and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is 
generally defined as a greater than 50% change, by value, in its equity ownership by certain stockholders over a three-year period, the corporation’s ability 
to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. As a result of the 
Company’s acquisition of Lung Therapeutics, the tax attributes have been limited under Section 382. The Company has reflected the reduction of these tax 
attributes within the income tax footnote at December 31, 2023.

There is also a risk that due to regulatory changes, such as suspensions on the use of net operating losses, or other unforeseen reasons, our existing 
net operating losses could expire or otherwise become unavailable to offset future income tax liabilities. In addition, state net operating losses generated in 
one state cannot be used to offset income generated in another state. For these reasons, even if we attain profitability, we may be unable to use a material 
portion of our net operating losses and other tax attributes.

We do not intend to pay dividends on our common stock so any returns will be limited to the value of our stock. 

We  currently  anticipate  that  we  will  retain  future  earnings  for  the  development,  operation  and  expansion  of  our  business  and  do  not  anticipate 
declaring or paying any cash dividends for the foreseeable future. Furthermore, future debt or other financing arrangements may contain terms prohibiting 
or  limiting  the  amount  of  dividends  that  may  be  declared  or  paid  on  our  common  stock.  Any  return  to  stockholders  will  therefore  be  limited  to  the 
appreciation of their stock. 

A significant portion of our total outstanding shares may be sold into the market at any time, which could cause the market price of our common 

stock to drop significantly, even if our business is doing well. 

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the 
market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. As of April 12, 2024, we had
16,972,512 shares of common stock outstanding and 12,523 shares of our Series X Preferred Stock outstanding, which were convertible into 12,523,000 
shares of common stock, subject to beneficial ownership limitations. 

Concurrently and in connection with the execution of the Lung Acquisition Agreement, our directors and officers  as of immediately after the Lung 
Acquisition, and the directors and officers of the majority shareholder of Lung immediately prior to the Lung Acquisition, entered into lock-up agreements 
with us, pursuant to which each such director, officer or stockholder is subject to a 180-day lockup on the sale or transfer of shares of common stock or any 
securities convertible into or exercisable or exchangeable for shares of common stock (including without limitation, shares of common stock or such other 
securities which may be deemed to be beneficially owned by each such director, officer or stockholder in accordance with the rules and regulations of the 
SEC and our securities which may be issued upon exercise of an option to purchase shares of common stock or a warrant to purchase shares of common 
stock) that were held by each such director, officer or stockholder at the closing of the Lung Acquisition and hereafter owned by each such director, officer 
or  stockholder,  including  those  shares  issued  in  the  Lung  Acquisition,  subject  to  certain  customary  exceptions.  Upon  expiration  of  this  180-day  lockup 
period, these shares will become eligible for sale in the public market. 

On the closing of the Financing, we entered into a Registration Rights Agreement with the Investors. Pursuant to the Registration Rights Agreement, 
we filed a resale registration statement with the SEC on January 29, 2024, which was declared effective on February 5, 2024. The shares subject to the 
resale  registration  statement  no  longer  constitute  restricted  securities  and  may  be  sold  freely  in  the  public  markets,  subject  to  lapse  on  any  related 
contractual restrictions related thereto of any Investor and subject to volume limitations applicable to affiliates.

We have also registered all shares of common stock that we may issue under our equity compensation plans, including upon exercise of outstanding 

options. These shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates. 

91

 
 
Assuming  the  conversion  of  all  outstanding  Series  X  Preferred  Stock  and  the  exercise  of  outstanding  Warrants,  there  is  a  concentration  of 
ownership of our outstanding common stock by one group of affiliated stockholders. If this group chooses to act together, it could exert substantial 
influence over our business, and the interests of this group may conflict with those of other stockholders. 

As  of  April  12,  2024,  entities  and  individuals  affiliated  with  Bios  Partners,  or  collectively,  the  Bios  Entities,  beneficially  owned  9.99%  of  our 
outstanding common stock. This ownership percentage does not, due to certain restrictions on conversion and exercisability, take into account the issuance 
of  all  shares  of  our  common  stock  upon  conversion  of  the  Series  X  Preferred  Stock  or  upon  exercise  of  the  Warrants  issued  to  the  Bios  Entities  in  the 
Financing. 

The Certificate of Designation for the Series X Preferred Stock provides that any holder of Series X Preferred Stock will not have a right to convert, 
subject to certain exceptions, the Series X Preferred Stock for our common stock if, as a result of such conversion, the holder, together with its affiliates and 
other attribution parties, would hold 19.99% of the total number of shares of our common stock then outstanding, subject to decrease upon written notice 
by the holder. Similarly, under the terms of the Warrants a holder shall not have the right to exercise any portion of any Warrant, to the extent that after 
giving effect to such exercise, the holder (together with its affiliates and any other persons acting as a group together with the holder or any of its affiliates), 
would  beneficially  own  in  excess  of  a  percentage  elected  by  the  holder  up  to  19.99%  of  the  number  of  shares  of  our  common  stock  outstanding 
immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. Assuming the 
conversion of all outstanding Series X Preferred Stock and the exercise of all outstanding warrants, options and any other rights to acquire our common 
stock, and without giving effect to the foregoing beneficial ownership limitations on Series X Preferred Stock and the Warrants, the Bios Entities would, as 
of April 12, 2024, own 45.8% of our common stock on a fully diluted basis. 

If any of the Bios Entities acted together, they could be able to exert substantial influence over our business. Additionally, the interests of the Bios 
Entities may be different from or conflict with the interests of our other stockholders. This concentration of voting power with the Bios Entities could delay, 
defer, or prevent a change of control, entrench our management and the Board of Directors, or delay or prevent a merger, consolidation, takeover, or other 
business combination involving us on terms that other stockholders may desire. In addition, conflicts of interest could arise in the future between us, on the 
one hand, and the Bios Entities on the other hand, concerning potential competitive business activities, business opportunities, the issuance of additional 
securities and other matters. 

Provisions  in  our  corporate  charter  documents  and  under  Delaware  law  could  make  an  acquisition  of  us,  which  may  be  beneficial  to  our 

stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management. 

Provisions in our certificate of incorporation and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of us 
that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for shares of common stock. 
These  provisions  could  also  limit  the  price  that  investors  might  be  willing  to  pay  in  the  future  for  shares  of  our  common  stock,  thereby  depressing  the 
market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these 
provisions  may  frustrate  or  prevent  any  attempts  by  our  stockholders  to  replace  or  remove  our  current  management  by  making  it  more  difficult  for 
stockholders to replace members of our board of directors. Among other things, these provisions: 

•

•

•

•

•

establish a classified board of directors such that not all members of the board are elected at one time; 

allow the authorized number of our directors to be changed only by resolution of our board of directors; 

limit the manner in which stockholders can remove directors from the board; 

establish advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of 
directors; 

require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written 
consent; 

92

 
 
•

•

•

 limit who may call stockholder meetings; 

authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that 
would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by 
our board of directors; and 

require the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal certain 
provisions of our charter or bylaws. 

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, 
which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after 
the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a 
prescribed manner. 

Our certificate of incorporation designates the state courts in the State of Delaware or, if no state court located within the State of Delaware has 
jurisdiction, the federal court for the District of Delaware, as the sole and exclusive forum for certain types of actions and proceedings that may be 
initiated by our stockholders, which could discourage lawsuits against the company and our directors, officers and employees. 

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the 
State  of  Delaware  (or,  if  the  Court  of  Chancery  does  not  have  jurisdiction,  the  federal  district  court  for  the  District  of  Delaware)  will  be  the  sole  and 
exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of 
our directors, officers or employees to our company or our stockholders, any action asserting a claim against us arising pursuant to any provision of the 
General Corporation Law of the State of Delaware or our certificate of incorporation or bylaws, or any action asserting a claim against us governed by the 
internal affairs doctrine. We do not expect this choice of forum provision will apply to suits brought to enforce a duty or liability created by the Securities 
Act, the Exchange Act of 1934, as amended, or any other claim for which federal courts have exclusive jurisdiction. This exclusive forum provision may 
limit the ability of our stockholders to bring a claim in a judicial forum that such stockholders find favorable for disputes with us or our directors, officers 
or employees, which may discourage such lawsuits against us and our directors, officers and employees.

Risk Management and Strategy

We  are  a  clinical  stage  biopharmaceutical  company,  with  no  commercial  operations  or  revenue  streams  and  our  sole  business  activity  has  been 
ongoing research into our drug therapies. We assess material risks from cybersecurity threats on an ongoing basis, including any potential unauthorized 
occurrence  on  or  conducted  through  our  information  systems  that  may  result  in  adverse  effects  on  the  confidentiality,  integrity,  or  availability  of  our 
information  systems  or  any  information  residing  therein.  As  our  company  grows,  we  plan  to  expand  our  strategy  for  cybersecurity  in  alignment  with 
nationally accepted standards. We have not encountered cybersecurity risks that have materially affected or are reasonably likely to materially affect us or 
our business strategy. For additional information regarding risks from cybersecurity threats, please refer to Item 1A, “Risk Factors,” in this Annual Report 
on Form 10-K.

Governance

Our  management  and  board  of  directors  recognize  the  critical  importance  of  maintaining  the  trust  and  confidence  of  our  business  partners  and 
employees, including the importance of managing cybersecurity risks as part of our larger risk management program. While all of our personnel play a part 
in managing cybersecurity risks, one of the key functions of our board of directors is informed oversight of our risk management process, including risks 
from cybersecurity threats. Our board of directors is responsible for monitoring and assessing strategic risk exposure, and 

93

 
 
our executive officers are responsible for the day-to-day management of the material risks that we face. Our Audit Committee, comprised of members with 
substantial experience in information technology governance and risk management, oversees our cybersecurity strategy. They are advised by a virtual CISO 
consultant with Certified Information Security Manager (CISM) and Certified Information Systems Security Professional (CISSP certifications, as well as 
extensive background in IT infrastructure, risk mitigation, and incident response planning.  In general, we seek to address cybersecurity risks through a 
cross-functional  approach  that  is  focused  on  preserving  the  confidentiality,  integrity,  and  availability  of  the  information  that  we  collect  and  store  by 
identifying, preventing, and mitigating cybersecurity threats and effectively responding to cybersecurity incidents when they occur.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations. 

The following discussion and analysis are meant to provide material information relevant to an assessment of the financial condition and results of 
operations of our Company, including an evaluation of the amounts and certainty of cash flows from operations and from outside sources, so as to allow 
investors to better view our Company from management’s perspective. You should read the following discussion and analysis of our financial condition and 
results of operations together with our audited consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-
K. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. 
Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors. We discuss factors that we 
believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under Item 1A. “Risk Factors” in this 
Annual Report on Form 10-K.

Overview and Recent Developments

We  are  a  clinical  stage  biopharmaceutical  company  focused  on  developing  novel  therapies  for  the  treatment  of  orphan  pulmonary  and  fibrosis 
indications with no approved or limited effective treatments. We currently have two product candidates in clinical development, LTI-03 and LTI-01, and 
multiple candidates in preclinical development focused on fibrosis indications. Our pipeline includes:

•

•

•

LTI-03,  a  peptide,  for  which  we  are  currently  recruiting  patients  for  a  Phase  1b  dose-ranging,  placebo-controlled  safety,  tolerability,  and 
pharmacodynamic biomarker activity trial in development for the treatment of IPF, that has demonstrated the ability to protect healthy lung 
epithelial cells and reduce pro-fibrotic signaling; 

LTI-01,  a  proenzyme  that  completed  a  Phase  2a  dose-ranging,  placebo-controlled  trial  and  a  Phase  1b  safety,  tolerability  and  proof  of 
mechanism trial in LPE patients, an indication that has no approved drug treatment; and 

preclinical programs targeting cystic fibrosis and a peptide program focused on the Cav1 protein for systemic fibrosis indications.

Prior to the termination of development of our main product candidate in February 2023 and the acquisition of Lung (as described below), our focus 
was the development of our main product candidate, ALRN-6924, a MDM2/MDMX dual inhibitor that leveraged our proprietary peptide drug technology.
Since our inception, we have devoted a substantial portion of our resources to developing our product candidates, including ALRN-6924, developing our 
proprietary stabilized cell-permeating peptide platform, building our intellectual property portfolio, business planning, raising capital and providing general 
and administrative support for these operations.

Announcement of Exploration of Strategic Alternatives

In  February  2023,  we  announced  a  review  of  initial  data  from  our  Phase  1b  chemoprotection  trial  of  ALRN-6924  in  patients  with  p53-mutated 
breast  cancer.  Based  on  these  findings,  we  decided  to  terminate  the  Phase  1b  breast  cancer  trial  and  further  development  of  ALRN-6924.    We  also 
announced that we were exploring a range of strategic alternatives to maximize shareholder value. We engaged Ladenburg Thalmann & Co., Inc. to act as a 
strategic advisor for this process. Strategic alternatives that were being evaluated included, but were not limited to, an acquisition, a merger, a business 
combination,  a  sale  of  assets  or  other  transactions.    In  addition,  in  February  2023,  we  determined  to  reduce  our  workforce  from  nine  to  three  full-time 
employees, which we completed in the second quarter of 2023.

The Lung Acquisition

On  October  31,  2023,  we  acquired  Lung  Therapeutics,  Inc.,  or  Lung,  pursuant  to  an  Agreement  and  Plan  of  Merger,  or  the  Lung  Acquisition 
Agreement. Following our acquisition of Lung, or the Lung Acquisition, the business conducted by Lung became the business primarily conducted by the 
Company  and  we  shifted  our  operating  disease  focus  to  advancing  a  pipeline  of  first-in-class  medicines  to  address  significant  unmet  medical  needs  in 
orphan pulmonary and fibrosis indications. 

96

 
 
Under the terms of the Lung Acquisition Agreement, at the closing of the Lung Acquisition, we issued to the stockholders of Lung 344,345 shares 
of our common stock and 19,903 shares of our newly designated Series X Preferred Stock. Each share of Series X Preferred Stock is convertible into 1,000 
shares of common stock.  In addition, we assumed (i) all Lung stock options and all warrants exercisable for Lung common stock immediately outstanding 
prior to the closing of the Lung Acquisition, each subject to adjustment pursuant to the terms of the Lung Acquisition Agreement.

Immediately following the closing of the Lung Acquisition, we entered into a Stock and Warrant Purchase Agreement, or the Purchase Agreement, 
with a group of accredited investors, or the Investors, led by Bio Partners, the majority stockholder of Lung prior to the closing of the Lung Acquisition, 
and  including  Nantahala  Capital,  as  well  as  additional  undisclosed  investors,  pursuant  to  which  we  issued  and  sold  (i)  an  aggregate  of  4,707  shares  of 
Series X Preferred Stock, and (ii) warrants to purchase up to an aggregate of 2,353,500 shares of common stock, or the Warrant Shares, for an aggregate 
purchase price of approximately $18.4 million, which included the conversion of certain convertible promissory notes in the aggregate principal amount of 
approximately $1.6 million issued by Lung to Bios Partners prior to the closing of the Lung Acquisition at a 10% discount to the per share price of the 
Series X Preferred Stock,, or the Financing, and collectively with the Lung Acquisition, the Transactions. The Financing closed on November 2, 2023.  

On  February  28,  2024,  we  held  our  2023  annual  meeting  of  stockholders  in  which  our  stockholders  approved  the  issuance,  in  accordance  with 
Nasdaq  Listing  Rule  5635(a),  of  shares  of  common  stock,  upon  conversion  of  our  outstanding  Series  X  Preferred  Stock.  Following  approval  of  the 
conversion of outstanding Series X Preferred Stock, the Company had approximately 29,495,512 shares of common stock issued and outstanding on a pro 
forma basis, which gives effect to the full conversion of the Series X Preferred Stock as of the date of our 2023 annual meeting of stockholders, without 
regard to beneficial ownership limitations that may limit the ability of certain holders of Series X Preferred Stock to convert such shares to common stock 
as  such  time.  On  March  5,  2024,  based  upon  existing  beneficial  ownership  limitations,  12,087  shares  of  Series  X  Preferred  Stock  were  automatically 
converted into 12,087,075 shares of common stock. The remaining approximately 12,522 shares of Series X Preferred Stock (which are convertible into 
12,522,925 shares of common stock) will remain convertible at the option of the holder thereof, subject to certain beneficial ownership limitations.

We  have  not  completed  the  development  of  any  of  our  product  candidates,  have  not  generated  any  revenue  from  product  sales  and  have  never 

generated an operating profit.

To date, we have financed operations primarily through $145.5 million in net proceeds from sales of common stock and warrants, $131.2 million 
from sales of preferred stock prior to our IPO, $34.9 million from a collaboration agreement in 2010, and $18.4 million in gross proceeds, less issuance 
costs of $0.9 million, in connection with the Financing following the Lung Acquisition, which included the conversion of certain convertible promissory 
notes in the aggregate principal amount of approximately $1.6 million issued by Lung to Bios Partners prior to the closing of the Lung Acquisition at a 
10% discount to the per share price of the Series X Preferred Stock.

Since our inception, we have incurred significant losses on an aggregate basis. Our net losses were $15.7 million and $27.3 million for the years 
ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated deficit of $288.5 million. These losses have resulted 
primarily from costs incurred in connection with research and development activities, licensing and patent investment and general and administrative costs 
associated  with  our  operations.  In  February  2023,  we  discontinued  development  of  ALRN-6924  which  substantially  reduced  our  operating  expenses. 
Notwithstanding these events, we expect to continue to incur operating losses for the foreseeable future. 

After the Lung Acquisition, we believe that, based on our current operating plan, our cash and cash equivalents of $17.3 million as of December 31, 
2023,  will  enable  us  to  fund  our  operating  expenses  into  the  fourth  quarter  of  2024  following  the  date  of  this  Annual  Report  on  Form  10-K.  We  have 
concluded that as of the date of this Annual Report on Form 10-K there is substantial doubt about our ability to continue as a going concern. Our funding 
estimates  are  based  on  assumptions  that  may  prove  to  be  wrong  and  we  could  use  our  available  capital  resources  sooner  than  we  currently  expect,  see 
“Liquidity and Capital Resources.” We intend to fund our operations primarily through utilization of our current financial resources and additional raises of 
capital.  Our  future  viability  is  dependent  on  our  ability  to  raise  additional  capital,  enter  into  a  financing,  consummate  a  successful  acquisition,  merger, 
business

combination, or a sale of assets or other transaction. If we become unable to continue as a going concern, we may have to liquidate our assets and the 
values we receive for our assets in liquidation or dissolution could be significantly lower than the values reflected in our consolidated financial statements. 

Components of Aileron’s Results of Operations

Revenue 

We have not generated any revenue from product sales and we do not expect to generate any revenue from the sale of products in the foreseeable 

future. 

Operating Expenses

Our expenses since inception have consisted solely of research and development costs, general and administrative, and restructuring costs.  

Research and Development Expenses

For  the  periods  presented  in  this  Annual  Report  on  Form  10-K,  research  and  development  expenses  consist  primarily  of  costs  incurred  for  our 

research activities, including our discovery efforts, and the development of our product candidates, and include: 

•

•

•

•

•

•

•

•

salaries, benefits and other related costs, including stock-based compensation expense, for personnel engaged in research and development 
functions; 

expenses incurred in connection with the clinical development of its product candidates, including under agreements with third parties, such 
as consultants and contract research organizations, or CROs;

the  cost  of  manufacturing  product  candidates  for  use  in  its  clinical  trials  and  preclinical  studies,  including  under  agreements  with  third 
parties, such as consultants and contract manufacturing organizations, or CMOs; 

expenses  incurred  in  connection  with  the  preclinical  development  of  its  product  candidates,  including  outsourced  professional  scientific 
development services, consulting research fees and payments made under sponsored research arrangements with third parties;

the costs of laboratory supplies and acquiring, developing and manufacturing preclinical study and clinical trial materials; 

third-party license fees; 

costs related to compliance with regulatory requirements; and 

facility-related  expenses,  which  included  direct  depreciation  costs  and  allocated  expenses  for  rent  and  maintenance  of  facilities  and  other 
operating costs. 

We expense research and development costs as incurred. We recognize costs for certain development activities, such as clinical trials, based on an 
evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided to us by our 
vendors and our clinical investigative sites. Payments for these activities are based on the terms of the individual agreements, which may differ from the 
pattern of costs incurred, and are reflected in our financial statements as prepaid or accrued research and development expenses.

In  addition,  we  typically  used  our  employee  and  infrastructure  resources  across  our  development  programs.  We  tracked  outsourced  development 
costs and milestone payments made under our licensing arrangements by product candidate or development program, but we did not allocate personnel 
costs,  license  payments  made  under  our  licensing  arrangements  or  other  internal  costs  to  specific  development  programs  or  product  candidates  because 
these costs are deployed across multiple programs and, as such, are not separately classified. 

98

 
 
Research and development activities are central to our business model. The duration, costs and timing of clinical trials and development of a product 

candidate will depend on a variety of factors, including: 

•

•

•

•

•

the  scope,  rate  of  progress,  expense  and  results  of  clinical  trials  of  the  product  candidate  that  we  are  developing  and  other  research  and 
development activities that we have conducted; 

uncertainties in clinical trial design and patient enrollment rates; 

significant and changing government regulation and regulatory guidance; 

the timing and receipt of any marketing approvals; and 

the expense of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights. 

A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the 
costs and timing associated with the development of that product candidate. For example, if the FDA, or another regulatory authority were to have required 
us to conduct clinical trials beyond those that we anticipated would be required for the completion of clinical development of a product candidate, or if we 
experienced  significant  trial  delays  due  to  patient  enrollment  or  other  reasons,  we  would  have  been  required  to  expend  significant  additional  financial 
resources and time on the completion of clinical development. 

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in our 
executive,  finance  and  corporate  and  administrative  functions.  General  and  administrative  expenses  are  comprised  of  professional  fees  associated  with 
being a public company including costs of accounting, auditing, legal, regulatory, tax and consulting services associated with maintaining compliance with 
exchange  listing  and  SEC  requirements,  director  and  officer  insurance  costs;  and  both  public  and  investor  relations  costs.  General  and  administrative 
expenses also include legal fees relating to patent and corporate matters; legal and other professional fees relating to our strategic process; other insurance 
costs; travel expenses; and facility-related expenses, which include direct depreciation costs and allocated expenses for rent and maintenance of facilities 
and other operating costs. 

Restructuring Costs 

Restructuring-related  charges  are  comprised  of  one-time  termination  costs  in  connection  with  the  reduction-in-workforce,  including  severance, 

benefits, and related costs. 

Other Income, net 

Interest and Other Income

Interest income consists of interest income earned on our cash and cash equivalents. Historically, our interest income had not been significant due to 
low investment balances and low interest earned on those balances. We anticipate that our interest income will fluctuate in the future in response to our 
cash and cash equivalents and the interest rate environment. 

Other income, net consists of gains or losses recognized from non-routine items such as accretion on short-term investments, and gains or losses 

recognized from foreign currency transactions, and the disposal of fixed assets.

Research  and  development  expenses  for  the  year  ended  December  31,  2023  were  $4.0  million,  compared  to  $18.0  million  for  the  year  ended 
December 31, 2022. The decrease of $14.0 million was primarily a result of reduced spending of $6.0 million for our completed Phase 1b NSCLC trial, 
$1.6  million  for  our  completed  healthy  volunteer  study,  $2.6  million  for  our  terminated  Phase  1b  breast  cancer  trial,  $2.0  million  for  ALRN-6924 
manufacturing costs, and $1.0 million for other research expenses, and reduced spending of $2.7 million for employee related expenses and facilities and 
other expenses, offset by the research and development expense of $1.4 million and employee related expenses of $0.5 million incurred by Lung during 
2023 after the acquisition.

during 2023 as compared to the year 2022 mainly due to the acquisition in October 2023, offset by $0.3 million lower headcount costs and $0.4 million 
lower facilities and other expenses during 2023 as compared to the year 2022.

Restructuring and Other  

On February 16, 2023, our Board of Directors determined to reduce the Company’s remaining workforce from nine to three full-time employees. 
The determination to affect the workforce reduction was made in connection with our decision to terminate the Phase 1b breast cancer trial of ALRN-6924 
and further development of ALRN-6924.

As a result of the above restructuring initiatives, we incurred restructuring-related charges of $0.9 million for the year ended December 31, 2023. 
Restructuring-related charges were comprised of one-time termination costs in connection with the reduction-in-workforce, including severance, benefits, 
and related costs.

Other Income, net

Other income, net of $0.5 million for the year ended December 31, 2023 consisted of interest income of $0.4 million and investment accretion of 
$0.2  million.  We  anticipate  that  our  interest  income  and  investment  accretion  will  fluctuate  in  the  future  in  response  to  our  then-current  cash  and  cash 
equivalents, and then-current interest rates.  

Income Taxes

As of December 31, 2023, we had federal and state net operating loss carryforwards of $56.5 million and $8.2 million, respectively, which begin to 
expire in 2036 and 2043, respectively. As of December 31, 2023, we also had federal research and development tax credit carryforwards of $1.1 million, 
which begin to expire in 2035. The Company also has federal orphan drug tax credit carryforwards of $6.7 million which begin to expire in 2039.

Utilization of the net operating loss carryforwards and research and development tax credit carryforwards may be subject to a substantial annual
limitation  under  Section  382  of  the  Internal  Revenue  Code  of  1986  due  to  ownership  changes  that  have  occurred  previously  or  that  could  occur  in  the 
future.  These  ownership  changes  may  limit  the  amount  of  carryforwards  that  can  be  utilized  annually  to  offset  future  taxable  income.  In  general,  an 
ownership change, as defined by Section 382, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a 
corporation by more than 50% over a three-year period. As a result of the Company’s acquisition of Lung Therapeutics, the tax attributes have been limited 
under Section 382. The Company has reflected the reduction of these tax attributes within the income tax footnote at December 31, 2023.

On October 31, 2023, the Company acquired, in accordance with the terms of the Merger Agreement, the stock of Lung Therapeutics. In accordance 
with  ASC  805-740-25-3,  recognition  of  deferred  tax  assets  and  liabilities  is  required  for  substantially  all  temporary  differences  and  acquired  tax 
carryforwards and credits. The Company has computed estimated temporary differences and acquired tax carryforwards and credits as of the transaction 
date. The Company will not have tax basis in intangible assets recorded as part of the purchase. For accounting purposes, the intangible assets will not be 
amortized and subject to impairment review and testing. Though the tax effects may be delayed indefinitely, ASC 740-10-55-63 states that “deferred tax 
liabilities may not be eliminated or reduced because a reporting entity may be able to delay the settlement of those liabilities by delaying the events that 
would cause taxable temporary differences to reverse.” As such, the Company has recorded a deferred tax liability for the portion of the liability that cannot 
be offset with indefinite lived deferred tax assets.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have incurred significant losses on an aggregate basis. We have not commercialized any product candidates, and as we do 
not have any product candidates under development, we do not expect to generate revenue from sales of any products. We have financed our operations 
through sales of common stock in our initial public offering and follow-on public offerings, sales of common stock and warrants in a private placement, 
sales of common stock in “at-the-market” offerings, sales of common stock under our equity line with Lincoln Park Capital LLC, or LPC, sales of preferred 
stock prior to our initial public offering, payments received under a collaboration agreement and sales of common stock, preferred stock and warrants in 
connection with the Lung Acquisition and the Financing. As of December 31, 2023, we had cash and cash equivalents of $17.3 million. 

101

 
 
At-the-Market Program 

In January 2021, we entered into a Capital on Demand Sales Agreement, or the ATM Sales Agreement, with JonesTrading Institutional Services 
LLC, or JonesTrading, and William Blair & Company, L.L.C., or William Blair, as agents, under which we may issue and sell shares of common stock, 
having an aggregate offering price of up to $30.0 million. Sales of common stock through JonesTrading and William Blair may be made by any method 
that is deemed an “at the market” offering as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended. We are not obligated to make any 
sales of common stock under the ATM Sales Agreement. Pursuant to a prospectus relating to the ATM Sales Agreement we filed with the SEC on June 21, 
2022, we may offer and sell shares of our common stock having an aggregate offering price of up to $14.0 million under the ATM Sales Agreement. There 
were no sales under the ATM Sales Agreement during the year ended December 31, 2023, or the year ended December 31, 2022. 

Equity Line Financing 

On September 21, 2020, we entered into a purchase agreement, or the Equity Line Purchase Agreement, with LPC for an equity line financing. The 
Equity Line Purchase Agreement provided that, subject to the terms and conditions set forth therein, we had the right, but not the obligation, to sell to LPC, 
and LPC is obligated to purchase up to $15.0 million of shares of common stock at our sole discretion, over a 36-month period that commenced in October 
2020. We filed a registration statement on Form S-1 covering the sale of shares of common stock that are issued to LPC under the Equity Line Purchase 
Agreement, which was declared effective on October 15, 2020. The Equity Line Purchase Agreement was terminated in October 2023 pursuant to the terms 
thereof.

There were no sales under the Equity Line Purchase Agreement during the years ended December 31, 2023 and 2022.

The Lung Acquisition and Financing Transaction

On October 31, 2023, we acquired Lung, a privately held biopharmaceutical company focused on developing novel therapies for the treatment of 
orphan  pulmonary  and  fibrosis  indications  that  have  no  approved  or  limited  effective  treatments.  Immediately  following  the  acquisition  of  Lung,  we 
entered into a definitive agreement for the sale of (i) 4,707 shares of Series X Non-Voting Convertible Preferred Stock, at par value of $0.001, or the Series 
X  Preferred  Stock,  and  (ii)  warrants  to  purchase  an  aggregate  of  2,353,500  shares  of  Aileron's  common  stock  in  a  private  placement  to  a  group  of 
accredited  investors  led  by  Bios  Partners,  all  affiliated  entities  are  collectively  called  Bios,  and  including  Nantahala  Capital,  as  well  as  additional 
undisclosed investors, or the Financing. 

The  Financing  resulted  in  gross  proceeds  to  Aileron  of  approximately  $18.4  million,  which  included  the  conversion  of  certain  convertible 
promissory  notes  in  the  aggregate  principal  amount  of  approximately  $1.6  million  issued  by  Lung  to  Bios  Partners  prior  to  the  closing  of  the  Lung 
Acquisition at a 10% discount to the per share price of the Series X Preferred Stock. The Financing closed on November 2, 2023. 

The  exercise  price  of  the  Warrants  is  $4.89  per  share,  subject  to  certain  price  and  share  adjustments,  including  for  stock  splits,  stock  dividends, 
recapitalizations, subdivisions, combinations, noncash distributions and cash dividends. The Warrants issued under the Financing will be exercisable any 
time after May 2, 2024, and on or prior to May 2, 2027. Payment for Warrant shares upon exercise of the Warrants may be (i) in cash or (ii) in the event 
that there is no registration statement available for the resale of Warrant shares, by cashless exercise.

Under the terms of the Warrants, the Company shall not effect the exercise of any portion of any Warrant, and a holder shall not have the right to 
exercise any portion of any Warrant, to the extent that after giving effect to such exercise, the holder (together with its affiliates and any other persons 
acting as a group together with the holder or any of its affiliates), would beneficially own in excess of a percentage elected by the holder up to 19.99% of 
the  number  of  shares  of  common  stock  outstanding  immediately  after  giving  effect  to  such  exercise,  as  such  percentage  ownership  is  determined  in 
accordance with the terms of the Warrants. However, any holder may, upon written notice to the Company, increase or decrease such percentage to any 
other percentage not in excess of 19.99%; provided that any 

102

 
 
increase or decrease in such percentage will not be effective until 61 days after such notice is delivered to the Company.

In connection with the Financing, we entered into a Registration Rights Agreement, or the Registration Rights Agreement, with certain investors. 
Pursuant to the Registration Rights Agreement, we filed a resale registration statement with the SEC on January 29, 2024, which was declared effective on 
February  5,  2024.  The  Registration  Rights  Agreement  also  contains  customary  terms,  including  an  obligation  to  indemnify  the  investors,  their  officers, 
directors, agents, partners, members, managers, stockholders, affiliates and employees under the registration statement from certain liabilities and pay all 
fees and expenses (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for the investors, except
for reasonable and documented fees and expenses in an amount not to exceed $30,000 of the investors that hold a majority in interest of the registrable 
securities in connection with the review of the registration statement) incident to our obligations under the Registration Rights Agreement.

During the year ended December 31, 2023, operating activities used $19.8 million of cash, primarily resulting from our net loss of $15.7 million and 
cash  provided  by  the  change  in  operating  assets  and  liabilities  of  $5.4  million  offset  by  non-cash  charges  of  $1.3  million.  Non-cash  charges  resulted 
primarily from stock-based compensation expense of $1.2 million. Changes in our operating assets and liabilities during the year ended December 31, 2023 
consisted primarily of an increase of $5.0 million in accounts payable, and $0.4 million in accrued expenses and other current liabilities.  

During the year ended December 31, 2022, operating activities used $24.9 million of cash, primarily resulting from our net loss of $27.3 million and 
cash  provided  by  the  change  in  operating  assets  and  liabilities  of  $0.4  million  offset  by  non-cash  charges  of  $2.0  million.  Non-cash  charges  resulted 
primarily  from  stock-based  compensation  expense.  Changes  in  our  operating  assets  and  liabilities  during  the  year  ended  December  31,  2022  consisted 
primarily of a decrease of $1.6 million in accrued expenses and other current liabilities, a decrease of $1.6 million in prepaid expense and other assets, and 
an increase of $0.5 million in accounts payable.  

Investing Activities

During  the  year  ended  December  31,  2023,  investing  activities  provided  $16.2  million  of  cash.  We  received  $16.3  million  of  proceeds  from  the 

maturities of investments, offset by $0.1 million of cash and cash equivalents from the Lung Acquisition.

During the year ended December 31, 2022, investing activities provided $26.5 million of cash. We received $48.3 million of proceeds from the sale 

of investments, offset by $21.9 million of purchases of investments.

Financing Activities

During the year ended December 31, 2023, net cash provided by financing activities was $15.8 million due to the proceeds of $15.8 million from the 

Financing in October 2023.

Off-Balance Sheet Arrangements

As of December 31, 2023 and 2022 and in the periods presented, we did not have any off-balance sheet arrangements, as defined in the rules and 

regulations of the SEC.

Critical Accounting Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which 
have  been  prepared  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States.  The  preparation  of  our  consolidated  financial 
statements  and  related  disclosures  requires  us  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities,  costs,  and 
expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical experience, 
known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on 
an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions. 

Accrued Research and Development Expenses

As  part  of  the  process  of  preparing  our  financial  statements,  we  are  required  to  estimate  our  accrued  research  and  development  expenses.  This 
process  involves  reviewing  open  contract  and  purchase  orders,  communicating  with  our  personnel  to  identify  services  that  have  been  performed  on  our 
behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise 
notified of the actual costs. Some of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual 
milestones are met; however, some require advanced payments. We make estimates of our accrued expenses as of each balance sheet date in our financial 
statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid 
to:

•

•

•

•

vendors in connection with preclinical and clinical development activities;

CROs in connection with performing research activities on our behalf and conducting preclinical studies and clinical trials on our behalf;

investigative sites or other service providers in connection with clinical trials; and

CMOs or other vendors in connection with the production of preclinical and clinical trial materials.

We  base  our  expenses  related  to  preclinical  studies  and  clinical  trials  on  our  estimates  of  the  services  received  and  efforts  expended  pursuant  to 
quotes and contracts with multiple CMOs and CROs that supply, conduct and manage clinical trials and preclinical studies on our behalf. The financial 
terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in 
which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these 
contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In recording accrued or prepaid 
service fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites activated and the level of effort to 
be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or 
amount of prepaid expense accordingly. 

Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of 
services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too 
low in any particular period. To date, we have not made any material adjustments to our prior estimates of accrued research and development expenses.

104

 
 
Stock-Based Compensation

We account for stock-based compensation awards in accordance with ASC Topic 718, Compensation—Stock Compensation, or ASC 718. ASC 718 
requires  all  stock-based  payments,  including  grants  of  stock  options  and  restricted  stock,  to  be  recognized  in  the  statements  of  operations  and 
comprehensive loss based on their fair values. We measure stock-based awards based on their fair value on the date of grant and recognize compensation 
expense for those awards over the requisite service period, which is generally the vesting period of the respective award. We apply the straight-line method 
of expense recognition to all awards with only service-based vesting conditions and apply the graded-vesting method to all awards with performance-based 
vesting conditions or to awards with both service-based and performance-based vesting conditions.

We estimate the fair value of each stock option grant at the date of grant using the Black-Scholes option pricing model and the fair value of each 
restricted common stock award is estimated on the date of grant based on the fair value of our common stock on that same date. The Black-Scholes option-
pricing model requires inputs based on certain subjective assumptions including the volatility of our common stock, the expected term of our stock options, 
the  risk-free  interest  rate  for  a  period  that  approximates  the  expected  term  of  our  stock  options  and  our  expected  dividend  yield.  Changes  to  these 
assumptions  can  materially  affect  the  fair  value  of  stock  options  and  ultimately  the  amount  of  stock-based  compensation  expense  recognized  in  our 
consolidated financial statements. 

We account for stock option forfeitures during the period in which they occur.

Income Taxes

We  account  for  income  taxes  using  the  asset  and  liability  method,  which  requires  the  recognition  of  deferred  tax  assets  and  liabilities  for  the 
expected future tax consequences of events that have been recognized in the financial statements or in our tax returns. Deferred taxes are determined based 
on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences 
are expected to reverse. 

We assess the likelihood that our deferred tax assets will be recovered from future taxable income and, to the extent we believe, based upon the 
weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is 
established through a charge to income tax expense. Changes in valuation allowances from period to period are included in our tax provision in the period 
of change. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible 
tax planning strategies. 

We  account  for  uncertainty  in  income  taxes  recognized  in  the  consolidated  financial  statements  by  applying  a  two-step  process  to  determine  the 
amount  of  tax  benefit  to  be  recognized.  First,  the  tax  position  must  be  evaluated  to  determine  the  likelihood  that  it  will  be  sustained  upon  external 
examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the 
amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 
50%  likelihood  of  being  realized  upon  ultimate  settlement.  The  provision  for  income  taxes  includes  the  effects  of  any  resulting  tax  reserves,  or 
unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties. 

The  recognition  and  measurement  of  tax  benefits  requires  significant  judgment,  especially  in  assessing  uncertain  tax  positions.  Judgments 
concerning the recognition and measurement of our tax benefits, as well as limitations surrounding their realizability, might change as new information 
becomes available.

Contractual Obligations 

Our wholly owned subsidiary, Lung Therapeutics LLC, leased a facility containing 6,455 square feet of office space located at 3801 S. Capital of 
Texas Hwy, Suite 330, Austin, Texas, which expired on March 31, 2024. We do not plan on renewing the lease. Following expiration of the lease, we plan 
to operate virtually.

105

 
 
 Our remaining contractual rent commitment under this lease was less than $0.1 million as of December 31, 2023. For a description of our lease 

obligations, refer to Note 15 to our consolidated financial statements appearing in this Annual Report on Form 10-K.

Emerging Growth Company Status

We ceased to qualify as an emerging growth company as of December 31, 2022, and are now subject to Section 14A(a) and (b) of the Securities 
Exchange Act of 1934, as amended, or the Exchange Act, beginning with our fiscal year that started January 1, 2023. However, notwithstanding the loss of 
our status as an emerging growth company, we will continue to be exempt from Section 404(b) of the Sarbanes-Oxley Act of 2002 for so long as we are 
neither a “large accelerated filer” nor an “accelerated filer” as those terms are defined in Rule 12b-2 under the Exchange Act.

We are a “smaller reporting company” as defined in Rule 12b-2 under the Exchange Act. We may continue to be a smaller reporting company if 
either (i) the market value of our shares held by non-affiliates is less than $250.0 million or (ii) our annual revenue was less than $100.0 million during the 
most recently completed fiscal year and the market value of our shares held by non-affiliates is less than $700.0 million. For so long as we continue to be a 
smaller reporting company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies.

Recently Issued Accounting Pronouncements

We have reviewed all recently issued standards and have determined that, other than as disclosed in Note 2 to our consolidated financial statements 
appearing at the end of this Annual Report on Form 10-K, such standards will not have a material impact on our consolidated financial statements or do not 
otherwise apply to our operations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company, as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended, for this reporting period and 

are not required to provide the information required under this item.

Item 8. Financial Statements and Supplementary Data

The consolidated financial statements required to be filed pursuant to this Item 8 are appended to this Annual Report on Form 10-K. An index of 

those consolidated financial statements is found in Item 15 of Part IV of this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Limitations on Effectiveness of Controls and Procedures

The  term  “disclosure  controls  and  procedures,”  as  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Securities  Exchange  Act  of  1934,  as 
amended, or the Exchange Act, refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the 
reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s 
rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be 
disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, 
including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding 
required disclosure.

106

 
 
In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well 
designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and 
procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible 
controls and procedures relative to their costs.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and principal financial officer, evaluated, as of the end of the period covered 
by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the 
Exchange Act of 1934). Based on that evaluation, our Chief Executive Officer and our principal financial officer concluded that our disclosure controls and 
procedures  were  not  effective  at  the  reasonable  assurance  level  as  of  December  31,  2023,  because  of  the  identified  material  weaknesses  in  our  internal 
control over financial reporting described below.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial 
reporting  is  defined  in  Rules  13a-15(f)  and  15d-15(f)  promulgated  under  the  Exchange  Act  as  a  process  designed  by,  or  under  the  supervision  of,  the 
Company’s  principal  executive  and  principal  financial  officers  and  effected  by  the  Company’s  Board,  management  and  other  personnel,  to  provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles and includes those policies and procedures that:

•

•

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of 
the company;

Provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with 
generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with 
authorizations of management and directors of the company; and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets 
that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems 
determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation.  Projections  of  any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree 
of compliance with the policies or procedures may deteriorate.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the Internal Control-Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded 
that  the  Company’s  internal  control  over  financial  reporting  was  not  effective  as  of  December  31,  2023  as  a  result  of  the  material  weakness  discussed 
below. 

We  identified  material  weaknesses  in  our  internal  control  over  financial  reporting.  A  material  weakness  is  a  deficiency,  or  combination  of 
deficiencies, in internal control over financial reporting such that there is a possibility that a material misstatement of our financial statements will not be 
prevented or detected on a timely basis. The material weaknesses primarily related to the accounting for the business combination with Lung Therapeutics, 
Inc., specifically the (i) lack of sufficient accounting and supervisory personnel to maintain appropriate segregation of duties relating to user access of the 
financial  accounting  system  and  who  have  the  appropriate  level  of  technical  accounting  experience  and  training,    (ii)  lack  of  evidence  over  reviews  of 
account reconciliations and supporting schedules, and (iii) lack of adequate procedures and controls to ensure that accurate financial statements could have 
been  prepared  and  reviewed  on  a  timely  basis  for  annual  reporting  purposes.  In  the  year  ended  December  31,  2023,  management  identified  material 
weaknesses related to the accounting for our acquisition of Lung, including a lack of 

107

 
 
sufficient  precision  in  the  performance  of  reviews  supporting  the  purchase  price  allocation  accounting,  and  a  lack  of  timely  oversight  over  third-party 
specialists and the reports they produced to support the accounting for the acquisition.

We are implementing procedures to remediate these material weaknesses, including the hiring of a full-time additional employee in our accounting 
department,  integration  into  one  accounting  system,  third  party  accounting  specialists  and  a  more  streamlined  process  in  order  to  prepare  and  review 
financial  information,  however,  our  control  environment  needs  improvement,  and  as  a  result  we  may  be  exposed  to  errors.  Our  remediation  plan  also 
includes  the  hiring  of  additional  accounting  employees  and/or  consultants  with  the  specific  technical  accounting  experience  necessary  to  assist  with 
complex, non-routine transactions and to support the timely completion of financial close procedures, the implementation of robust processes, and to assist 
with  the  preparation  of  financial  statements  and  our  compliance  with  SEC  reporting  obligations.  Additionally,  we  intend  to  develop  and  implement 
consistent accounting policies, internal control procedures and provide additional training to our accounting and financial reporting personnel. While we 
are working to remediate such weakness as quickly and efficiently as possible, we cannot at this time, provide an estimate of the timeframe we expect in 
connection with implementing our plan to remediate the material weaknesses.

Changes in Internal Control Over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) has occurred during 

the quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

Rule 10b5-1 Trading Plans

During  the  three  months  ended  December  31,  2023,  none  of  the  Company’s  directors  or  executive  officers  adopted, modified  or  terminated  any 
contract, instruction or written plan for the purchase or sale of Company securities that was intended to satisfy the affirmative defense conditions of Rule 
10b5-1(c) or any “non-Rule 10b5-1 trading arrangement” (as defined in Item 408(c) of Regulation S-K).

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections

None.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Aileron Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the balance sheet of Aileron Therapeutics, Inc. (the “Company”) as of December 31, 2022, and the related statements of operations 
and  comprehensive  loss,  of  stockholders’  equity  and  of  cash  flows  for  the  year  then  ended,  including  the  related  notes  (collectively  referred  to  as  the 
“financial  statements”).  In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of 
December 31, 2022, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted 
in the United States of America.

Substantial Doubt about the Company’s Ability to Continue as a Going Concern

The financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial 
statements, the Company has incurred losses and negative cash flows from operations and had an accumulated deficit that raise substantial doubt about its 
ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include 
any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s 
financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) 
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit of these financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and 

perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the  financial  statements.  Our  audit  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors of
Aileron Therapeutics, Inc. 

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Aileron Therapeutics, Inc. (the “Company”) as of December 
31, 2023, the related consolidated statements of operations and comprehensive loss, changes in convertible preferred stock and 
stockholders’ equity and cash flows for the year ended December 31, 2023, and the related notes  (collectively referred to as the 
“financial statements”).  In our opinion, the financial statements present fairly, in all material respects, the financial position of 
the Company as of December 31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023 
in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph – Going Concern 

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going 
concern. As more fully described in Note 1, the Company has a significant working capital deficiency, has incurred significant 
losses  and  needs  to  raise  additional  funds  to  meet  its  obligations  and  sustain  its  operations.  These  conditions  raise  substantial 
doubt  about  the  Company's  ability  to  continue  as  a  going  concern.  Management's  plans  in  regard  to  these  matters  are  also 
described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of 
this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the  Company's  financial  statements  based  on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  Public  Company 
Accounting  Oversight  Board  (United  States)  ("PCAOB")  and  are  required  to  be  independent  with  respect  to  the  Company  in 
accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange 
Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to 
error  or  fraud.  The  Company  is  not  required  to  have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over 
financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but 
not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company's  internal  control  over  financial  reporting. 
Accordingly, we express no such opinion. 

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to 
error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis, 
evidence regarding the amounts

and  disclosures  in  the  financial  statements.  Our  audit  also  included  evaluating  the  accounting  principles  used  and  significant 
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our 
audit provides a reasonable basis for our opinion.

Critical Audit Matters 

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that 
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are 
material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The 
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and 
we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the 
accounts or disclosures to which they relate.

Business Combination

Critical Audit Matter Description

As described in Note 3 to the financial statements, the Company acquired Lung Therapeutics, Inc. on October 31, 2023.  This 
acquisition was accounted for as a business combination. We identified the evaluation of the acquisition-date fair value of the 
intangible assets acquired as a critical audit matter.

The principal consideration for our determination that the evaluation of the acquisition-date fair values of the intangible assets 
acquired was a critical audit matter is the high degree of subjective auditor judgment associated with evaluating management’s 
determination of the fair values of the acquired intangible assets, which is primarily due to the complexity of the valuation 
models used and the sensitivity of the underlying significant assumptions. The key assumptions used within the valuation models 
included prospective financial information such as future revenue growth and an applied discount rate. The calculated fair values 
are sensitive to changes in these key assumptions.

How the Critical Audit Matter was Addressed in the Audit

Our audit procedures related to the evaluation of acquisition-date fair values of intangible assets acquired included the following, 
among others:

•

•

•

We evaluated the reasonableness of the purchase price allocation analysis from management and the third-party 
specialist engaged by management.

We assessed the qualifications and competence of management and the third-party specialist.

We evaluated the methodologies used to determine the fair values of the intangible assets.

F-3

 
 
 
 
 
 
 
 
 
 
•

•

•

We tested the assumptions used within the discounted cash flow models to estimate the fair values of the intangible 
assets, which included key assumptions such as the future revenue growth and the applied discount rate.

We assessed the reasonableness of management’s forecast by inquiring with management to understand how the 
forecast was developed and comparing the projections to external sources, including industry trends and peer 
companies’ historical data.

We involved our internal valuation specialist who assisted in the evaluation and testing performed on the 
reasonableness of significant assumptions to the models, including the applied discount rate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in thousands, except share and per share data)

1. Nature of the Business

Aileron  Therapeutics,  Inc.  (“Aileron”  or  the  “Company”)  was  a  clinical  stage  chemoprotection  oncology  company.  The  Company's  product 
candidate,  ALRN-6924,  was  a  MDM2/MDMX  dual  inhibitor  that  leverages  its  proprietary  peptide  drug  technology.  In  February  2023,  the  Company 
decided to terminate further development of ALRN-6924. Refer to Note 10 for more details on the restructuring event in 2023.

On October 31, 2023, Aileron acquired Lung Therapeutics, Inc. (“Lung Therapeutics” or "Lung") pursuant to an Agreement and Plan of Merger, 
dated October 31, 2023 (the “Lung Acquisition Agreement”), by and among the Company, AT Merger Sub I, Inc., a Delaware corporation and its wholly 
owned subsidiary, or First Merger Sub, AT Merger Sub II, LLC, a Delaware limited liability company and its wholly owned subsidiary, or Second Merger 
Sub,  and  Lung.  Pursuant  to  the  Lung  Acquisition  Agreement,  First  Merger  Sub  merged  with  and  into  Lung,  pursuant  to  which  Lung  was  the  surviving 
entity and became its wholly owned subsidiary, or the First Merger. Immediately following the First Merger, Lung merged with and into Second Merger 
Sub,  pursuant  to  which  Second  Merger  Sub  was  the  surviving  entity,  such  merger,  together  with  the  First  Merger,  the  Lung  Acquisition.  Lung  was 
incorporated on November 13, 2012 under the laws of the state of Texas. Its principal offices are in Austin, Texas. Following the Lung Acquisition, the 
Company  shifted  its  operating  disease  focus  to  advancing  a  pipeline  of  first-in-class  medicines  to  address  significant  unmet  medical  needs  in  orphan 
pulmonary and fibrosis indications with the potential to greatly improve patient outcomes over currently available treatments. Following expiration of the 
lease on March 31, 2024, the Company expects to operate virtually for the foreseeable future.

The Company is subject to risks and uncertainties common to clinical-stage companies in the biotechnology industry, including, but not limited to 
the risk that the Company never achieves profitability, the need for substantial additional financing, the risk of relying on third parties, risks of clinical trial 
failures, dependence on key personnel, protection of proprietary technology, and compliance with government regulations. The Company’s lead product 
candidate, LTI-03, is being developed for the treatment of Idiopathic Pulmonary Fibrosis (“IPF”) and has completed a healthy volunteer Phase 1a clinical 
trial.  LTI-03  is  currently  in  a  Phase  1b  clinical  trial  in  IPF  patients.  The  Company’s  second  product  candidate,  LTI-01,  is  in  development  for  loculated 
pleural effusion (“LPE”). The Company has completed Phase 1b and Phase 2a clinical trials in LPE patients.     

Liquidity and Going Concern

In  accordance  with  Accounting  Standards  Update  (“ASU”)  No.  2014-15,  Disclosures  of  Uncertainties  about  an  Entity’s  Ability  to  Continue  as  a 
Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial 
doubt about the Company’s ability to continue as a going concern within one year after the date the accompanying consolidated financial statements were 
issued. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented 
as of the date the consolidated financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its 
plans  sufficiently  alleviates  substantial  doubt  about  the  company’s  ability  to  continue  as  a  going  concern.  The  mitigating  effect  of  management’s  plans, 
however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the consolidated 
financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial 
doubt  about  the  entity’s  ability  to  continue  as  a  going  concern  within  one  year  after  the  date  that  the  financial  statements  are  issued.  Generally,  to  be 
considered probable of being effectively implemented, the plans must have been approved before the date that the consolidated financial statements are 
issued.

The  Company’s  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  to  operate  as  a  going  concern, 
which  contemplates  the  continuity  of  operations,  realization  of  assets  and  the  satisfaction  of  liabilities  in  the  ordinary  course  of  business.  Through 
December  31,  2023,  the  Company  has  financed  its  operations  primarily  through  $145,467  in  net  proceeds  from  sales  of  common  stock  and  warrants, 
$131,211 from sales of 

F-9

 
 
preferred  stock  prior  to  its  initial  public  offering  (“IPO”),  and  $34,910  from  a  collaboration  agreement  in  2010,  and  $18,429  in  gross  proceeds,  less
issuance costs of $893, in connection with the financing following the Lung Acquisition, which included the conversion of certain convertible promissory 
notes in the aggregate principal amount of approximately $1,553 issued by Lung to Bios Partners prior to the closing of the Lung Acquisition at a 10% 
discount to the per share price of the Series X non-voting convertible preferred stock (“Series X Preferred Stock”), or the Financing, and collectively with 
the Lung Acquisition, the Transactions.

After the Lung Acquisition, management believes that, based on the Company’s current operating plan, the Company’s cash and cash equivalents of 
$17,313 as of December 31, 2023, will enable Aileron to fund its operating expenses and capital expenditure requirements for at least six months following 
the date of this Annual Report on Form 10-K. Since its inception, the Company has not generated any revenue from product sales and have never generated 
an operating profit. The Company has incurred significant losses on an aggregate basis. The Company’s net losses were $15,732 and $27,329 for the years 
ended December 31, 2023 and 2022, respectively. As  of  December  31,  2023,  the  Company  had  an  accumulated  deficit  of  $288,517. These losses have 
resulted  primarily  from  costs  incurred  in  connection  with  research  and  development  activities,  licensing  and  patent  investment  and  general  and 
administrative  costs  associated  with  the  Company's  operations.  In  February  2023,  the  Company  discontinued  development  of  ALRN-6924  which 
substantially reduced its operating expenses. Notwithstanding these events, management expects to continue to incur operating losses for the foreseeable 
future  until  the  Company  completes  development  and  approval  of  its  product  candidates.  The  Company  will  continue  to  fund  its  operations  primarily 
through utilization of its current financial resources and additional raises of capital.

These  conditions  raise  substantial  doubt  about  the  Company’s  ability  to  continue  as  a  going  concern  for  at  least  one  year  from  the  date  those 
consolidated financial statements are issued. The Company plans to address these conditions by raising funds from its current investors, potential outside 
investors  and  other  funding  sources.  However,  there  is  no  assurance  that  such  funding  will  be  available  to  the  Company,  will  be  obtained  on  terms 
favorable  to  the  Company  or  will  provide  the  Company  with  sufficient  funds  to  meet  its  objectives.  The  Company’s  funding  estimates  are  based  on 
assumptions that may prove to be wrong, and the Company could use its available capital resources sooner than it currently expects. The Company’s future 
viability is dependent on its ability to raise additional capital, enter into a financing, consummate a successful acquisition, merger, business combination, or 
a sale of assets or other transaction. If the Company becomes unable to continue as a going concern, it may have to liquidate its assets and the values it 
receives for its assets in liquidation or dissolution could be significantly lower than the values reflected in its consolidated financial statements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United 
States  of  America  (“U.S.  GAAP”).  Any  reference  in  these  notes  to  applicable  guidance  is  meant  to  refer  to  the  authoritative  GAAP  as  found  in  the 
Accounting Standards Codification (“ASC”) and as amended by ASUs of the Financial Accounting Standards Board (“FASB”). 

Principles of Consolidation 

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, Lung Therapeutics, 
LLC,  Lung  Therapeutics  Australia  Pty  Ltd,  and  Lung  Therapeutics  Limited.  All  intercompany  balances  and  transactions  have  been  eliminated  in 
consolidation. 

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that 
affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported 
amounts of revenue and expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements 
include, but are not limited to, the accrual for research and development expenses, the value of stock-based 

F-10

 
 
compensation, the purchase price allocation for the Lung Acquisition, and the valuation of warrants. Estimates are periodically reviewed in light of changes 
in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those 
estimates. 

Foreign Currency Transactions 

The functional currency for the Company’s wholly owned foreign subsidiary, Lung Therapeutics Australia Pty Ltd., is the United States dollar. All 

foreign currency transaction gains and losses are recognized in the consolidated statements of operations and comprehensive loss. 

Concentration of Credit Risk and of Significant Suppliers 

Financial  instruments  that  potentially  expose  the  Company  to  concentrations  of  credit  risk  consist  primarily  of  cash  and  cash  equivalents. 
Periodically, the Company maintains balances in operating accounts above federally insured limits. The Company deposits its cash in financial institutions 
that it believes have high credit quality. The Company has not experienced any losses on such accounts and does not believe it is exposed to any significant 
credit risk on cash and cash equivalents. 

The  Company  is  dependent  on  third-party  manufacturers  to  supply  products  for  research  and  development  activities  of  its  programs,  including 
preclinical  and  clinical  testing.  In  particular,  the  Company  relied  on  a  small  number  of  manufacturers  to  supply  it  with  its  requirements  for  the  active 
pharmaceutical  ingredients  and  formulated  drugs  related  to  these  programs.  These  programs  could  have  been  adversely  affected  by  a  significant 
interruption in the supply of active pharmaceutical ingredients and formulated drugs.

Cash and Cash Equivalents

The  Company  maintains  cash  balances  in  various  accounts,  including  those  insured  by  the  Federal  Deposit  Insurance  Corporation  (FDIC).  The 

FDIC provides insurance coverage up to applicable limits for deposits held in participating financial institutions.

The  Company  considers  all  short-term,  highly  liquid  investments  with  original  maturities  of  90  days  or  less  at  the  acquisition  date  to  be  cash 

equivalents. The Company’s cash equivalents are comprised of funds held in money market accounts and are measured at fair value on a recurring basis.

Restricted Cash

As  of  December  31,  2023  and  December  31,  2022,  restricted  cash  of  $25  consisted  of  cash  deposited  in  a  separate  restricted  bank  account  as  a

security deposit for the Company’s corporate credit cards.

Fair Value Measurements

Certain  assets  and  liabilities  are  carried  at  fair  value  under  GAAP.  ASC  820,  Fair  Value  Measurement  (“ASC  820”),  establishes  a  fair  value 
hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own 
assumptions (unobservable inputs). Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit 
price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. 
Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets 
and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are 
considered observable and the last is considered unobservable.

•

•

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted 
prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by 
observable market data.

F-11

 
 
•

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the 
assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value 
requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in 
Level  3.  A  financial  instrument’s  level  within  the  fair  value  hierarchy  is  based  on  the  lowest  level  of  any  input  that  is  significant  to  the  fair  value 
measurement.

The  Company’s  cash  equivalents  are  carried  at  fair  value,  determined  according  to  the  fair  value  hierarchy  described  above  (see  Note  3).  The 

carrying values of the Company’s accounts payable and accrued expenses approximate their fair value due to the short-term nature of these liabilities.

Property and Equipment 

Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation  and  amortization.  Depreciation  and  amortization  expense  is  recognized 

using the straight-line method over the following estimated useful lives: 

Computer equipment and software
Furniture and fixtures

3 to 5 years
7 years

Expenditures for repairs and maintenance of assets are charged to expense as incurred. Upon retirement or sale, the cost and related accumulated 
depreciation and amortization of assets disposed of are removed from the accounts and any resulting gain or loss is included in the consolidated statements 
of operations and comprehensive loss. 

Leases

The Company accounts for leases under ASC Topic 842, Leases (“ASC 842”). Under ASC 842, at inception of a contract, the Company determines 
whether  an  arrangement  is  or  contains  a  lease.  For  all  leases,  the  Company  determines  the  classification  as  either  operating  leases  or  financing  leases. 
Operating leases are included in operating lease right-of-use assets and operating lease liabilities in the Company’s consolidated balance sheets.

Lease  recognition  occurs  at  the  commencement  date  and  lease  liability  amounts  are  based  on  the  present  value  of  lease  payments  over  the  lease 
term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. If a 
lease does not provide information to determine an implicit interest rate, the Company uses its incremental borrowing rate in determining the present value 
of lease payments. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term, and lease liabilities represent 
the Company’s obligation to make lease payments under the lease. ROU assets also include any lease payments made prior to the commencement date and 
exclude lease incentives received. Operating lease payments are expensed using the straight-line method as a general and administrative expense over the 
lease term. The depreciable life of assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase 
option reasonably certain of exercise. The Company has elected to apply the practical short-term expedient to leases with a lease term of 12 months or less, 
which does not subject the leases to capitalization.

The Company has an operating lease of office space, which has a remaining lease term of less than one year and includes one or more options to 
renew or terminate early. The Company determines if an arrangement contains a lease at inception. Operating lease right-of-use assets and lease liabilities 
are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Certain adjustments to the 
right-of-use  asset  may  be  required  for  items  such  as  prepaid  or  accrued  lease  payments,  initial  direct  costs  paid  or  incentives  received.  The  Company’s 
leases do not contain an implicit rate, and therefore the Company uses an estimated incremental borrowing rate based on the information available at the 
lease commencement date in determining the present value of lease payments. Options to extend or terminate the lease are reflected in the calculation when 
it  is  reasonably  certain  that  the  option  will  be  exercised.  The  Company  has  elected  to  account  for  lease  and  non-lease  components  as  a  single  lease 
component, however non-lease components that are variable, such as common area maintenance and utilities, are generally paid separately from rent based 
on actual costs incurred and therefore are not 

F-12

 
 
 
 
included in  the  right-of-use  asset  and  operating  lease  liability  and  are  reflected  as  an  expense  in  the  period  incurred.  Leases  with  an  initial  term  of  12 
months or less are not recorded on the consolidated balance sheet.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill represents the excess of the purchase price of an acquired business over the amount assigned to the assets acquired and liabilities assumed. 
The Company's indefinite-lived intangible assets, which consist of in-process research and development ("IPR&D"), acquired in the Lung Acquisition were 
recorded at fair value on their acquisition date. Goodwill and indefinite-lived intangible assets are not amortized but are subject to impairment testing on an 
annual basis as of December 31 or more frequently if events or circumstances indicate a potential impairment. The Company accounts for goodwill and 
indefinite-lived  intangible  assets  in  accordance  with  ASC  350,  Intangibles  Goodwill  and  Other,  and  Accounting  Standards  Update,  or  ASU  2017-04, 
Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The Company’s goodwill and intangible assets are deductible 
for tax purposes.

Impairment of Long-Lived Assets 

Long-lived  assets  consist  of  property  and  equipment,  goodwill  and  intangible  assets.  Long-lived  assets  to  be  held  and  used  are  tested  for 
recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors 
that  the  Company  considers  in  deciding  when  to  perform  an  impairment  review  include  significant  underperformance  of  the  business  in  relation  to 
expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review 
is performed to evaluate a long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use 
and eventual disposition of the long-lived asset to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash 
flows expected to result from the use of an asset are less than its carrying amount. The impairment loss would be based on the excess of the carrying value 
of the impaired asset over its fair value, determined based on discounted cash flows. 

In performing the Company’s annual goodwill impairment test, the Company is permitted to first assess qualitative factors to determine whether it is 
more  likely  than  not  that  the  fair  value  of  the  Company’s  reporting  unit  exceeds  its  carrying  amount,  including  goodwill.  In  performing  the  qualitative 
assessment, the Company considers certain events and circumstances specific to the reporting unit and to the entity as a whole, such as macroeconomic 
conditions, industry and market considerations, overall financial performance and cost factors when evaluating whether it is more likely than not that the 
fair value of the reporting unit exceeds its carrying amount. The Company is also permitted to bypass the qualitative assessment and proceed directly to the 
quantitative assessment. If the Company chooses to undertake the qualitative assessment and concludes that it is more likely than not that the fair value of 
the  reporting  unit  is  less  than  its  carrying  amount,  the  Company  would  then  proceed  to  the  quantitative  impairment  assessment.  In  the  quantitative 
assessment,  the  Company  compares  the  fair  value  of  the  reporting  unit  to  its  carrying  amount,  which  includes  goodwill.  If  the  fair  value  exceeds  the 
carrying value, no impairment loss exists. If the fair value is less than the carrying amount, a goodwill impairment loss is measured and recorded.

To date, the Company has not recorded any impairment losses on long-lived assets. For additional details regarding goodwill and intangible assets, 

refer to Note 7.

Series X Convertible Preferred Stock 

The  Company  has  classified  its  Series  X  convertible  preferred  stock,  referred  to  as  Series  X  Preferred  Stock,  as  temporary  equity  in  the 
accompanying consolidated  balance  sheets  due  to  terms  that  allow  for  redemption  of  the  shares  in  cash  upon  certain  change  in  control  events  that  are 
outside of the Company’s control, including sale or transfer of control of the Company as holders of the Series X Preferred Stock could cause redemption 
of the shares in these situations. The Company did not accrete the carrying values of the preferred stock to the redemption values since a liquidation event 
was not considered probable as of December 31, 2023. Subsequent adjustments of the carrying values to the ultimate redemption values will be made only 
when it becomes probable that such a liquidation event will occur.

Research and Development Costs 

Research  and  development  costs  are  expensed  as  incurred.  Research  and  development  expenses  are  comprised  of  costs  incurred  in  performing 
research  and  development  activities,  including  stock-based  compensation  and  benefits,  facilities  costs,  costs  of  clinical  trials,  sponsored  research, 
manufacturing, and external costs of outside vendors engaged to conduct preclinical development activities and trials. 

Costs incurred in obtaining technology licenses are immediately recognized as research and development expense if the technology licensed has not 

reached technological feasibility and has no alternative future uses. 

The Company has entered into various research and development and other agreements with commercial firms, researchers, universities, and others 
for provisions of goods and services. These agreements are generally cancelable, and the related costs are recorded as research and development expenses 
as incurred. Research and development expenses include costs for salaries, employee benefits, subcontractors, facility-related expenses, depreciation and 
amortization, stock-based compensation, laboratory supplies, and external costs of outside vendors engaged to conduct discovery, preclinical and clinical 
development activities, and clinical trials as well as to manufacture clinical trial materials, and other costs. The Company records accruals for estimated 
ongoing research and development costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or clinical 
trials, including the phase or completion of events, invoices received and contracted costs. Significant judgments and estimates are made in determining the 
accrued balances at the end of any reporting period. Actual results could differ materially from the Company’s estimates. Nonrefundable advance payments 
for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such prepaid expenses are 
recognized as an expense when the goods have been delivered or the related services have been performed, or when it is no longer expected that the goods 
will be delivered, or the services rendered. 

Upfront payments, milestone payments and annual maintenance fees under license agreements are expensed in the period in which they are incurred 

in the consolidated statements of operations and comprehensive loss.

Patent Costs 

All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about 

the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses. 

Accounting for Stock-Based Compensation 

The Company measures all stock options and other stock-based awards granted to employees, directors and non-employee consultants based on the 
fair  value  on  the  date  of  the  grant  and  recognizes  compensation  expense  of  those  awards,  net  of  forfeitures,  over  the  requisite  service  period,  which  is 
generally the vesting period of the respective award. The Company applies the straight-line method of expense recognition to all awards with only service-
based  vesting  conditions  and  applies  the  graded  vesting  method  to  all  awards  with  performance-based  vesting  conditions  or  both  service-based  and 
performance-based vesting conditions. 

The Company recognizes compensation expense for only the portion of awards that are expected to vest. The Company accounts for forfeitures as 
they occur. For performance-based awards, the Company does not recognize expense until the underlying vesting conditions are deemed to be probable of
occurrence.

The Company classifies share-based compensation expenses in its statement of operations and comprehensive loss in the same manner in which the 
award recipient's payroll costs are classified or in which the award recipient's service payments are classified, either to general and administrative expenses 
or research and development expenses.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company estimates its 
expected stock volatility based on the historical volatility of its own traded stock price. For options with service-based vesting conditions, the expected 
term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The expected 
term of 

F-14

 
 
stock options granted to non-employees is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the 
U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected 
dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future. 
The quoted market price of the Company’s common stock is used to estimate the fair value of the stock-based awards at grant date.

Income Taxes 

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for 
the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred taxes are 
determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in 
which the differences are expected to reverse. 

The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based 
upon  the  weight  of  available  evidence,  that  it  is  more  likely  than  not  that  all  or  a  portion  of  the  deferred  tax  assets  will  not  be  realized,  a  valuation 
allowance is established through a charge to income tax expense. Changes in valuation allowances from period to period are included in the Company’s tax 
provision in the period of change. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering 
prudent and feasible tax planning strategies. 

The  Company  accounts  for  uncertainty  in  income  taxes  recognized  in  the  financial  statements  by  applying  a  two-step  process  to  determine  the 
amount  of  tax  benefit  to  be  recognized.  First,  the  tax  position  must  be  evaluated  to  determine  the  likelihood  that  it  will  be  sustained  upon  external 
examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the 
amount of benefit to recognize in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 
50%  likelihood  of  being  realized  upon  ultimate  settlement.  The  provision  for  income  taxes  includes  the  effects  of  any  resulting  tax  reserves,  or 
unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties. 

Inflation Reduction Act of 2022

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a 
new U.S. federal 1% excise tax on certain repurchases of stock by publicly traded U.S. domestic corporations and certain U.S. domestic subsidiaries of 
publicly  traded  foreign  corporations  occurring  on  or  after  January  1,  2023.  The  excise  tax  is  imposed  on  the  repurchasing  corporation  itself,  not  its 
shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time 
of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new 
stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The 
U.S. Department of the Treasury (the “Treasury”) has been given authority to provide regulations and other guidance to carry out and prevent the abuse or 
avoidance of the excise tax.

Any redemption or other repurchase that occurs after December 31, 2022, in connection with a business combination, extension vote or otherwise, 
may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a business combination, 
extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with 
the  business  combination,  extension  or  otherwise,  (ii)  the  structure  of  a  business  combination,  (iii)  the  nature  and  amount  of  any  private  investment  in 
public  equity  (“PIPE”)  or  other  equity  issuances  in  connection  with  a  business  combination  (or  otherwise  issued  not  in  connection  with  a  business 
combination but issued within the same taxable year of a business combination) and (iv) the content of regulations and other guidance from the Treasury. In 
addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise 
tax  have  not  been  determined.  The  foregoing  could  cause  a  reduction  in  the  cash  available  on  hand  to  complete  a  business  combination  and  in  the 
Company’s ability to complete a business combination.

Segment Information 

The  Company  manages  its  operations  as  a  single  segment  for  the  purposes  of  assessing  performance  and  making  operating  decisions.  The 
Company’s  singular  focus  is  on  developing  novel  therapies  for  the  treatment  of  orphan  pulmonary  and  fibrosis  indications  with  no  approved  or  limited 
effective treatments. All of the Company’s tangible assets are held in the United States. The Company views its operations and manages its business in one 
operating segment operating exclusively in the United States.

Comprehensive Loss 

Comprehensive loss includes net loss as well as other changes in stockholders’ equity (deficit) that result from transactions and economic events 
other than those with stockholders. The Company’s other comprehensive loss in all periods presented includes unrealized gains (losses) on available-for-
sale investments and foreign currency translation adjustments.

Net Loss per Share

Basic  net  loss  per  share  attributable  to  common  stockholders  is  computed  by  dividing  the  net  loss  attributable  to  common  stockholders  by  the 
weighted  average  number  of  shares  of  common  stock  outstanding  for  the  period.  Diluted  net  loss  attributable  to  common  stockholders  is  computed  by 
adjusting  loss  per  share  attributable  to  common  stockholders  to  reallocate  undistributed  earnings  based  on  the  potential  impact  of  dilutive  securities. 
Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the 
weighted  average  number  of  shares  of  common  stock  outstanding  for  the  period,  including  potential  dilutive  common  shares.  For  purpose  of  this 
calculation, outstanding options and warrants to purchase common stock are considered potential dilutive common shares.

Acquisition Accounting

The fair value of the consideration exchanged in a business combination is allocated to tangible assets and identifiable intangible assets acquired and 
liabilities assumed at acquisition date fair value. Goodwill is measured as the excess of the consideration transferred over the net fair value of identifiable 
assets  acquired  and  liabilities  assumed.  The  accounting  for  an  acquisition  involves  a  considerable  amount  of  judgment  and  estimation.  Cost,  income, 
market  or  a  combination  of  approaches  may  be  used  to  establish  the  fair  value  of  consideration  exchanged,  assets  acquired,  and  liabilities  assumed, 
depending  on  the  nature  of  those  items.  The  valuation  approach  is  determined  in  accordance  with  generally  accepted  valuation  methods.  Key  areas  of 
estimation and judgment may include the selection of valuation approaches, cost of capital, market characteristics, cost structure, impacts of synergies, and 
estimates of terminal value, among other factors.

While the Company uses estimates and assumptions as part of the purchase price allocation process to estimate the fair value of assets acquired and 
liabilities assumed, estimates are inherently uncertain and subject to refinement. During the measurement period, which may be up to one year from the 
acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill, to the extent 
that adjustments are identified to the preliminary purchase price allocation. Upon conclusion of the measurement period, or final determination of the value 
of the assets acquired and liabilities assumed, whichever comes first, any subsequent adjustments are recorded to results of operations.

Recently Adopted Accounting Pronouncements 

On January 1, 2023, the Company adopted ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on 
Financial  Instruments,  for  the  fiscal  year  beginning  January  1,  2023  using  the  modified  retrospective  approach,  and  no  cumulative  effect  adjustment  to 
accumulated deficit was needed as of the adoption date. Additionally, no prior period amounts were adjusted. The new standard adjusts the accounting for 
assets held on an amortized cost basis, including short-term investments accounted for as available-for-sale, and receivables. The standard eliminates the 
probable initial recognition threshold and requires an entity to reflect its current estimate of all expected credit losses. The allowance for credit losses is a 
valuation account that is deducted from the amortized 

F-16

 
 
cost basis of the financial assets to present the net amount expected to be collected. The adoption of this standard did not have a material impact on the 
Company’s consolidated financial statements and related disclosures.

Accounting Pronouncements Not Yet Adopted

In  October  2023,  the  FASB  issued  ASU  2023-06—Disclosure  Improvements:  Codification  Amendments  in  Response  to  the  SEC’s  Disclosure 
Update and Simplification Initiative, to clarify or improve disclosure and presentation requirements of a variety of Topics. ASU 2023-06 adds 14 of the 27 
identified  disclosure  or  presentation  requirements  to  the  Codification.  However,  each  amendment  in  the  ASU  will  only  become  effective  if  the  SEC 
removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The effective dates of ASU 2023-06 will depend, 
in part, on whether an entity is already subject to the SEC’s current disclosure requirements. For such entities and those that must “file or furnish financial 
statements with or to the SEC in preparation for the sale of or for purposes of issuing securities that are not subject to contractual restrictions on transfer,” 
the  effective  date  for  each  amendment  will  be  the  date  on  which  the  SEC’s  removal  of  that  related  disclosure  requirement  from  Regulation  S-X  or 
Regulation S-K becomes effective, with early adoption prohibited. For all other entities, the amendments will be effective two years after the date of such 
removal. The Company is currently assessing the effect of this ASU on its consolidated financial statements and related disclosures.

In  November  2023,  the  FASB  issued  ASU  2023-07—Segment  Reporting  (Topic  280):  Improvements  to  Reportable  Segment  Disclosures,  to 
improve the disclosures about a public entity’s reportable segments and address requests from investors for additional, more detailed information about a 
reportable segment’s expenses. All public entities will be required to report segment information in accordance with the new guidance starting in annual 
periods beginning after December 15, 2023. The Company plans to adopt the ASU for the fiscal year beginning January 1, 2024. Since the Company has 
only one reportable segment, the Company will need to disclose the title and position of the chief operating decision maker (“CODM”) and an explanation 
of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources, as well 
as disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the CODM. The Company is currently assessing the 
effect of this ASU on its consolidated financial statements and related disclosures.

In  December  2023,  the  FASB  issued  ASU  2023-09—Income  Taxes  (Topic  740):  Improvements  to  Income  Tax  Disclosures,  to  address  investor 
requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation 
and income taxes paid information as well as certain other amendments to improve the effectiveness of income tax disclosures. The amendments in this 
update are effective for annual periods beginning after December 15, 2024. The Company does not expect adoption of this ASU to have a material impact 
on  its  results  of  operations,  financial  condition,  and  its  consolidated  financial  statements  other  than  adding  new  disclosures,  which  the  Company  is 
currently evaluating, as the Company has not recorded any net tax provision for the periods presented due to the losses incurred and the need for a full 
valuation allowance on net deferred tax assets.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a 

future date are not expected to have a material impact on the Company’s consolidated financial statements and related disclosures upon adoption.

3. Business Acquisition

On  October  31,  2023,  Aileron  acquired  100%  of  Lung,  pursuant  to  the  Lung  Acquisition  Agreement.  At  the  closing  of  the  Lung  Acquisition, 
Aileron issued to the stockholders of Lung 344,345 shares of its common stock (excluding 221 fractional shares from the total 344,566 shares pursuant to 
the  Lung  Acquisition  Agreement)  and  19,903  shares  of  its  newly  designated  Series  X  Preferred  Stock  (excluding  238  fractional  shares  from  the  total 
20,141 shares pursuant to the Lung Acquisition Agreement). Each share of Series X Preferred Stock is convertible into 1,000 shares of common stock. The 
Company paid $290 cash in lieu of fractional shares of both common stock and Series X Preferred Stock. In addition, Aileron assumed all Lung's stock 
options (1,780,459) and all warrants (726,437) 

F-17

 
 
exercisable for Lung common stock immediately outstanding prior to the closing of the Lung Acquisition, each subject to adjustment pursuant to the terms 
of the Lung Acquisition Agreement.

Immediately following the closing of the Lung Acquisition, on October 31, 2023, Aileron entered into a Stock and Warrant Purchase Agreement 
(the “Purchase Agreement” or the "PIPE") with a group of accredited investors, pursuant to which Aileron issued and sold (i) an aggregate of 4,707 shares 
of Series X Preferred Stock, and (ii) warrants (the “Warrants”) to purchase up to an aggregate of 2,353,500 shares of Aileron common stock (the “Warrant 
Shares”), for an aggregate purchase price of approximately $18,429, which included the conversion of certain convertible promissory notes in the aggregate 
principal  amount  of  $1,553  issued  by  Lung  to  Bios  Partners,  the  majority  stockholder  of  Lung  prior  to  the  closing  of  the  Lung  Acquisition,  at  a  10% 
discount  to  the  per  share  price  of  the  Series  X  Preferred  Stock.  The  Financing  closed  on  November  2,  2023.  Subject  to  stockholder  approval  for  the 
conversion rights of the Series X Preferred Stock, each share of Series X Preferred Stock is convertible into 1,000 shares of common stock.

The net proceeds from the Financing of approximately $17,536 are expected to be used to advance Aileron’s clinical development pipeline, business 

development activities, working capital and other general corporate purposes.

The  Lung  Acquisition  was  accounted  for  under  the  acquisition  method  of  accounting  under  ASC  805.  Under  the  acquisition  method,  the  total 
purchase price of the acquisition is allocated to the net tangible and identifiable intangible assets acquired and liabilities assumed based on the fair values as 
of the date of the acquisition. Consideration transferred is the sum of the acquisition-date fair values of the assets transferred, the liabilities incurred by the 
acquirer  to  the  former  owners  of  the  acquiree,  and  the  equity  interests  issued  by  the  acquirer  to  the  former  owners  of  the  acquiree  (except  for  the 
measurement of share-based payment awards). The total purchase price consideration consisted of the following:

Fair value of common stock issued to Lung stockholders
Fair value of Series X Preferred Stock issued to Lung stockholders
Cash in lieu of fractional shares
Fair value of the options assumed
Fair value of the warrants assumed

As of December 31, 2023, the Company had 5,000,000 shares of preferred stock, par value $0.001 per share, authorized, out of which 24,610 shares 
of  Series  X  Preferred  Stock  were  issued  and  outstanding.  As  of  December  31,  2022,  the  Company  had  5,000,000  shares  of  preferred  stock,  par  value 
$0.001 per share, authorized, and no shares of preferred stock issued or outstanding. 

On October 31, 2023 Aileron acquired Lung. Under the terms of the Lung Acquisition Agreement, at the closing of the Lung Acquisition, Aileron 
issued to the stockholders of Lung 344,345 shares of the common stock of Aileron, par value $0.001 per share, and 19,903 shares of Series X Preferred 
Stock.  

Immediately  following  the  closing  of  the  Lung  Acquisition,  on  October  31,  2023,  Aileron  entered  into  the  Purchase  Agreement  with  a  group  of 
accredited investors, pursuant to which Aileron issued and sold 4,707 shares of Series X Preferred Stock and Warrants to purchase up to an aggregate of 
2,353,500 shares of Aileron common stock. Refer to Note 3 for more details on the Financing in connection with the Purchase Agreement.

Since the Series X Preferred Stock was sold as a unit with the Warrants according to the Purchase Agreement, the proceeds received were allocated 
to each instrument on a relative fair value basis. Total gross proceeds of $18,429 reduced by $893 of the issuance costs were allocated as follows: $16,795 
to the Series X Preferred Stock and $741 to the Warrants. The Series X Preferred Stock and the Warrants issued in the Financing were recorded at par value 
of $0.001.

The  Company  evaluated  the  Series  X  Preferred  Stock  for  liability  classification  in  accordance  with  the  provisions  of  ASC  480,  Distinguishing 
Liabilities from Equity ("ASC 480"), and determined that equity treatment was appropriate because the Series X Preferred Stock did not meet the definition 
of the liability instruments. Specifically, the Series X Preferred Stock is not mandatorily redeemable and does not embody an obligation to buy back the 
shares outside of the Company’s control in a manner that could require the transfer of assets. The Company determined that the Series X Preferred Stock 
would be recorded as temporary equity, based on the guidance of ASC 480, given that it is contingently redeemable (see below).

Subject to stockholders’ approval, each share of Series X Preferred Stock is convertible into 1,000 shares of Common Stock. The preferences, rights, 

and limitations initially applicable to the Series X Preferred Stock are set forth in the Certificate of Designation. 

The Series X Preferred Stock has the following characteristics:

Voting

Except as otherwise required by law, the Series X Preferred Stock does not have voting rights. However, as long as any shares of Series X Preferred 
Stock  are  outstanding,  the  Company  will  not,  without  the  affirmative  vote  of  the  holders  of  a  majority  of  the  then  outstanding  shares  of  the  Series  X 
Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series X Preferred Stock or alter or amend the Certificate of 
Designation, amend or repeal any provision of, or add any provision to, the Certificate of Incorporation or by-laws of the Company, or file any articles of 
amendment, certificate of designations, preferences, limitations and relative rights of any series of preferred stock, if such action would adversely alter or 
change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series X Preferred Stock, (ii) issue further shares of
Series X Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of Series X Preferred Stock, or (iii) enter into 
any agreement with respect to any of the foregoing. Additionally, the approval of the holders of a 

F-21

 
 
majority  of  the  Series  X  Preferred  Stock  is  required  for  certain  change  of  control  transactions,  provided  that  this  approval  right  will  terminate  upon 
stockholders’ approval of the conversion proposal. 

Dividends

Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Preferred Stock equal, on an as-if-converted-to-common-
stock  basis,  and  in  the  same  form  as  dividends  actually  paid  on  shares  of  the  common  stock.  Such  dividends  are  not  cumulative.  Since  the  Company’s 
inception, no dividends have been declared or paid.

Liquidation, dissolution or winding up

The Series X Preferred Stock does not have a preference upon any liquidation, dissolution or winding-up of the Company. 

 Upon liquidation, dissolution or winding up of the Company, the Series X preferred stockholders shall be entitled to receive an equivalent amount 
of distributions as would be paid on the common stock underlying the Series X Preferred Stock, determined on an as-converted basis, pari passu with any 
distributions to the common stock shareholders.

Conversion

Subject to stockholders’ approval of the conversion proposal, the Series X Preferred Stock is convertible into common stock at a rate of 1,000 shares 
of common stock for every one share of Series X Preferred Stock that is converted. The Series X Preferred Stock is subject to certain beneficial ownership 
limitations, including that a holder of Series X Preferred Stock is prohibited from converting shares of Series X Preferred Stock into shares of common 
stock if, as a result of such conversion, such holder (together with its affiliates and any other persons acting as a group together with the holder or any of its 
affiliates) would beneficially own more than a specified percentage (to be initially set at 19.99% and thereafter adjusted by the holder to a number not to 
exceed 19.99%) of the total number of shares of common stock issued and outstanding immediately after giving effect to such conversion.

At the 2023 Annual Meeting on February 28, 2024, the Company’s stockholders approved the issuance of shares of common stock, upon conversion 

of its outstanding Series X Preferred Stock. Refer to Note 18 for more details on the 2023 Annual Meeting.

Redemption

Shares of the Series X Preferred Stock are not redeemable at the election of the holder except for in the event the Company would have been unable 
to  obtain  an  affirmative  stockholder  vote  at  the  2023  Annual  Meeting  to  permit  conversion,  each  holder  of  Series  X  Preferred  Stock  would  have  been 
entitled to elect, at the holder’s option, to have the shares of Series X Preferred Stock be redeemed by the Company and equal to the estimated fair value of 
the Series X Preferred Stock share at the time of redemption. Due to this redemption feature, as of December 31, 2023, the Series X Preferred Stock was 
classified within temporary equity on the consolidated balance sheet.

Maturity

The Series X Preferred Stock shall be perpetual unless converted.

12. Common Stock

As of December 31, 2023 and 2022, the Company was authorized to issue 45,000,000 shares of common stock, par value $0.001 per share. As of 
December 31, 2023, the Company had 4,885,512 shares of common stock issued and outstanding. As of December 31, 2022, the Company had 4,541,167 
shares of common stock issued and outstanding. 

F-22

 
 
Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders 
are entitled to receive dividends, as may be declared by the Company’s board of directors, if any. As of December 31, 2023 and 2022, no dividends had 
been declared. 

In the event of liquidation or dissolution, the holders of the common stock are entitled to receive proportionately all assets available for distribution 

to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Issuance of Common Stock

As disclosed above, on October 31, 2023, the Company issued to the stockholders of Lung 344,345 shares of the common stock of Aileron, par 
value  $0.001  per  share,  under  the  terms  of  the  Lung  Acquisition  Agreement.  In  addition,  Aileron  assumed  (i)  all  Lung  stock  options  immediately 
outstanding  prior  to  the  First  Merger,  each  becoming  an  option  for  common  stock  subject  to  adjustment  pursuant  to  the  terms  of  the  Lung  Acquisition 
Agreement,  and  (ii)  all  warrants  exercisable  for  Lung  common  stock  immediately  outstanding  prior  to  the  First  Merger,  each  becoming  a  warrant  to 
purchase common stock, subject to adjustment pursuant to the terms of the Lung Acquisition Agreement. Immediately following the closing of the Lung 
Acquisition, the Company had 4,885,512 shares of common stock issued and outstanding. 

As  disclosed  in  the  Note  3  above,  immediately  following  the  closing  of  the  Lung  Acquisition,  on  October  31,  2023,  Aileron  entered  into  the 
Purchase Agreement with a group of accredited investors, pursuant to which Aileron issued and sold 4,707 shares of Series X Preferred Stock and warrants 
to purchase up to an aggregate of 2,353,500 shares of Aileron common stock. The exercise price of the Warrants is $4.89 per share, subject to certain price 
and share adjustments, including for stock splits, stock dividends, recapitalizations, subdivisions, combinations, reclassifications, noncash distributions, and 
cash dividends. The Warrants will be exercisable any time after the later of May 2, 2024, the date the requisite stockholder approval is obtained, and on or 
prior to May 2, 2027. Payment for Warrant shares upon exercise of the Warrants may be (i) in cash or (ii) in the event that there is no registration statement 
available for the resale of Warrant shares, by cashless exercise.

Under the terms of the Warrants, the Company shall not effect the exercise of any portion of any Warrant, and a holder shall not have the right to 
exercise any portion of any Warrant, to the extent that after giving effect to such exercise, the holder (together with its affiliates and any other persons 
acting as a group together with the holder or any of its affiliates), would beneficially own in excess of a percentage elected by the holder up to 19.99% of 
the  number  of  shares  of  common  stock  outstanding  immediately  after  giving  effect  to  such  exercise,  as  such  percentage  ownership  is  determined  in 
accordance with the terms of the Warrants. However, any holder may, upon written notice to the Company, increase or decrease such percentage to any 
other percentage not in excess of 19.99%; provided that any increase or decrease in such percentage will not be effective until 61 days after such notice is 
delivered to the Company.

The Company has assessed the Warrants for appropriate equity or liability classification and determined the Warrants are freestanding instruments 
that do not meet the definition of a liability pursuant to ASC 480 and do not meet the definition of a derivative pursuant to ASC 815, Derivatives and 
Hedging (“ASC 815”). The Warrants are indexed to the Company’s common stock and meet all other conditions for equity classification under ASC 480 
and ASC 815. Accordingly, the Warrants are classified as equity and accounted for as a component of additional paid-in capital at the time of issuance. The 
Warrants were initially recognized at their relative fair value in the amount of $741 at the time of issuance determined using Black-Scholes option-pricing 
model and will not be remeasured.

Reverse Stock Split 

The Company’s stockholders approved a reverse stock split of the Company’s common stock on June 15, 2022. The Company effected the Reverse 
Stock Split on November 10, 2022. Pursuant to the Reverse Stock Split, every 20 shares of the Company’s issued and outstanding shares of common stock 
were automatically combined into one issued and outstanding share of common stock, without any change in the par value per share of the common stock. 
The  Reverse  Stock  Split  reduced  the  authorized  number  of  shares  of  common  stock  from  300,000,000 to 15,000,000  and,  pursuant  to  the  certificate  of 
amendment, such reduced authorized number of shares of common stock was subsequently multiplied by three, such that following the Reverse Stock Split 
the Company has 45,000,000 shares of 

F-23

 
 
common stock authorized. The Reverse Stock Split affected all issued and outstanding shares of the Company’s common stock, and the respective numbers 
of  shares  of  common  stock  underlying  the  Company’s  outstanding  stock  options,  outstanding  warrants  and  the  Company’s  equity  incentive  plans  were 
proportionately adjusted. All share and per share amounts disclosed give effect to the Reverse Stock Split on a retroactive basis.

As of December 31, 2023, 4,885,512 shares of common stock were issued and outstanding, no shares were held in treasury, and 24,610 shares of 

Series X Preferred Stock were issued and outstanding. In addition, as of December 31, 2023, there were: 

•

•

•

•

24,847,000 shares of common stock reserved for issuance upon conversion of the Series X Preferred Stock;

2,212,102 shares of common stock issuable upon the exercise of options under existing equity incentive plans, of which 1,780,459 options 
were assumed through the Lung Acquisition;

416,617 and 7,500 shares of common stock reserved for issuance under the 2021 Plan and 2017 Employee Stock Purchase Plan, respectively, 
as well as any automatic increases in the number of shares of the common stock reserved under these plans; and

3,726,696  shares  of  common  stock  reserved  for  issuance  upon  exercise  of  outstanding  warrants.  The  warrants  consist  of  (i)  warrants  to 
purchase 646,759 shares of the Company’s common stock, with an exercise price of $40.00 per share, which were issued in the April 2019 
private placement, which expire on April 2, 2024; (ii) warrants to purchase 726,437 shares of the Company’s common stock, with an exercise 
price of $5.66, which expire on May 20, 2029, which were assumed in connection with the Lung Acquisition, and (iii) warrants to purchase 
2,353,500 shares of the Company’s common stock, which were issued and sold in the Financing as described above.

Accordingly,  as  of  December  31,  2023,  out  of  the  45,000,000  shares  of  common  stock  presently  authorized,  36,095,427  shares  are  issued  and 

outstanding or reserved for issuance and 8,904,573 shares of common stock remain available for future issuance.

13. Stock-Based Awards

As  of  December  31,  2023,  the  Company  had  five  equity  compensation  plans,  each  of  which  was  approved  by  its  stockholders:  2006  Equity 
Incentive  Plan,  as  amended  (the  “2006  Plan”),  2016  Stock  Incentive  Plan  (the  “2016  Plan”),  2017  Stock  Incentive  Plan  (the  “2017  Plan”),  2021  Stock 
Incentive  Plan  (the  “2021  Plan”),  and  2017  Employee  Stock  Purchase  Plan  (the  “2017  ESPP”).  The  Company  also  assumed  Lung’s  2013  Long-Term 
Incentive Plan (the “2013 Plan”) as a result of the Lung Acquisition. 

As of December 31, 2023, the Company had 9,482 shares to be issued upon exercise of outstanding options under the 2006 Plan; 8,404 shares to be
issued upon exercise of outstanding options under the 2016 Plan, and 130,903 shares to be issued upon exercise of outstanding options under the 2017 Plan. 
No outstanding options under the 2006 Plan, the 2016 Plan, or the 2017 Plan as of December 31, 2023. As such, no shares remained available for future 
issuance under the 2006 Plan, the 2016 Plan, or the 2017 Plan as of December 31, 2023.

Shares that are expired, terminated, surrendered or canceled without having been fully exercised will be available for future awards. In addition, 
shares  of  common  stock  that  are  tendered  to  the  Company  by  a  participant  to  exercise  an  award  are  added  to  the  number  of  shares  of  common  stock 
available for the grant of awards.

The exercise price for stock options granted may not be less than the fair market value of the common stock as of the date of grant.

2021 Stock Incentive Plan

The Company’s 2021 Plan was approved by the Company’s stockholders on June 15, 2021 and became effective on June 16, 2021. Under the 2021 
Plan, the Company may grant incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, awards of restricted 
stock units and other stock-based awards. The 

F-24

 
 
Company’s employees, officers, directors, consultants and advisors are eligible to receive awards under the 2021 Plan; however, incentive stock options 
may only be granted to employees. The 2021 Plan is administered by the Company’s Board of Directors (the “Board”) or, at the discretion of the Board, by 
a committee of the Board. The number of shares of common stock covered by options and the date those options become exercisable, type of options to be 
granted, exercise prices, vesting and other restrictions are determined at the discretion of the Board, or its committee if so delegated.

Stock  options  granted  under  the  2021  Plan  with  service-based  vesting  conditions  generally  vest  over  four years  and  may  not  have  a  duration  in 

excess of ten years, although options have been granted with vesting terms of less than four years.

The  total  number  of  shares  of  common  stock  that  may  be  issued  under  the  2021  Plan  was  840,254  as  of  December  31,  2023,  of  which  416,617 
shares remained available for grant. The Company initially reserved 625,000 shares of common stock, plus the number of shares of common stock subject 
to  outstanding  awards  under  the  2017  Plan,  the  2016  Plan  and  the  2006  Plan  that  expire,  terminate  or  are  otherwise  surrendered,  canceled,  forfeited  or 
repurchased by the Company at their original issuance price pursuant to a contractual repurchase right up to 314,006 shares. 

2017 Stock Incentive Plan

The 2017 Plan was approved by the Company’s stockholders on June 16, 2017, and became effective on June 28, 2017. Under the 2017 Plan, the 
Company could grant incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, awards of restricted stock units 
and other stock-based awards. The Company’s employees, officers, directors, consultants and advisors were eligible to receive awards under the 2017 Plan; 
however, incentive stock options could only be granted to employees. The 2017 Plan is administered by the Board or, at the discretion of the Board, by a 
committee  of  the  Board.  The  number  of  shares  of  common  stock  covered  by  options  and  the  date  those  options  become  exercisable,  type  of  options 
granted, exercise prices, vesting and other restrictions were determined at the discretion of the Board, or its committee if so delegated.

Stock  options  granted  under  the  2017  Plan  with  service-based  vesting  conditions  generally  vest  over  four years  and  may  not  have  a  duration  in 
excess of ten years, although options have been granted with vesting terms of less than four years. The exercise price for stock options granted may not be 
less than the fair market value of the common stock as of the date of grant.

As of the effective date of the 2021 Plan, the Board determined to grant no further awards under the 2017 Plan.

Shares that are expired, terminated, surrendered or canceled without having been fully exercised under the 2017 Plan will be available for future 
awards under the 2021 Plan. In addition, shares of common stock that are tendered to the Company by a participant to exercise an award are added to the 
number of shares of common stock available for the grant of awards under the 2021 Plan.

2017 Employee Stock Purchase Plan

On  June  16,  2017,  the  Company’s  stockholders  approved  the  2017  ESPP,  which  became  effective  on  June  28,  2017.  Under  the  2017  ESPP,  the 
number of shares of common stock that may be issued under the 2017 ESPP will automatically increase on each January 1, beginning with the fiscal year 
ended December 31, 2018 and continuing for each fiscal year until, and including, the fiscal year ending December 31, 2027, equal to the least of (i) 31,120 
shares, (ii) 1% of the outstanding shares of common stock on such date and (iii) an amount determined by the Company’s Board. On January 1, 2023 and 
January 1, 2024, no additional shares were reserved for issuance under the 2017 ESPP pursuant to this provision. 7,500 shares remained available for future 
issuance under the 2017 ESPP as of December 31, 2023. 

2013 Stock Incentive Plan

F-25

 
 
The Company assumed the Lung’s 2013 Plan as a result of the Lung Acquisition. In October 2013, Lung’s Board of Directors (“Lung’s Board”) 
approved  the  2013  Plan  to  provide  long-term  incentives  for  its  employees,  non-employee  directors  and  certain  consultants.  As  of  December  31,  2023, 
1,780,459 shares were reserved to be issued upon exercise of options outstanding under the 2013 Plan, and 726,437 shares to be issued upon exercise of 
outstanding warrants under Lung’s 2013 Plan. These options and warrants were assumed by the Company in connection with the Lung Acquisition. 

Before the Lung Acquisition, the 2013 Plan was administered by the Lung’s Board or, at the discretion of the Lung’s Board, by a committee of the 
Lung’s Board. The exercise prices, vesting and other restrictions are determined at the discretion of the Lung’s Board, or its committee if so delegated, 
except that the exercise price per share of stock options may not be less than 100% of the fair market value of the share of common stock on the date of 
grant and the term of stock option may not be greater than ten years. The vesting periods for equity awards are determined by the Board, but generally are 
four  years.  The  contractual  term  for  stock  option  awards  is  ten  years.  The  vesting  periods  for  equity  awards  were  determined  by  Lung’s  Board,  but 
generally are four years. The contractual term for stock option awards is ten years. Following the closing of the Lung Acquisition on October 31, 2023, no 
further awards can be granted under the 2013 Plan.

Stock Option Valuation

The assumptions that the Company used to determine the grant-date fair value of the stock options granted to employees and directors during the 

years ended December 31, 2023 and 2022 and at the Lung Acquisition date were as follows, presented on a weighted average basis:

respectively.

The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the 
Company’s  common  stock  for  those  stock  options  that  had  exercise  prices  lower  than  the  fair  value  of  the  Company’s  common  stock.  There  were  no 
options exercised during the year ended December 31, 2023. The aggregate intrinsic value of stock options exercised during the year ended December 31, 
2022 was $0.

Stock-Based Compensation

The  Company  recorded  stock-based  compensation  expense  related  to  stock  options  in  the  following  expense  categories  of  its  statements  of 

operations and comprehensive loss:

The  Company’s  potential  dilutive  securities,  which  include  stock  options  as  of  December  31,  2023  and  2022,  have  been  excluded  from  the 
computation of diluted net loss per share attributable to common stockholders whenever the effect of including them would be to reduce the net loss per 
share. In periods where there is a net loss, the weighted average number of shares of common stock outstanding used to calculate both basic and diluted net 
loss per share attributable to common stockholders is the same. The following potential shares of common stock, presented based on amounts outstanding 
at each period end, were excluded from the calculation of diluted net loss per share attributable to common stockholders for the periods indicated because 
including them would have had an anti-dilutive effect:

On  March  26,  2021,  the  Company  entered  into  a  sublease  agreement  (the  “Sublease”)  by  and  among  the  Company,  Vittoria  Industries  North 
America, Inc. (the “Sublessor”) and Waterfront Equity Partners, LLC (the “Lessor”), under which the Company was leasing approximately 3,365 square 
feet of office space located at 285 Summer Street, Unit 101, Boston, Massachusetts (the “Premises”). The Sublease was subject and subordinate to a lease 
agreement, dated as of July 13, 2012, by and between the Sublessor and Lessor, pursuant to which the Sublessor is leasing the Premises from the Lessor. 
The Sublease expired March  31,  2023,  and  the  Company  did  not  renew  the  Sublease.  Following  expiration  of  the  Sublease,  the  Company  is  operating
virtually, and expects to do so in the foreseeable future. 

On August 16, 2021, Lung Therapeutics entered into an operating lease agreement to rent approximately 6,455 square feet of office space for its 
corporate headquarters in Austin, Texas, beginning on October 1, 2021. The lease agreement is for a 30-month term that ended on March 31, 2024, and 
includes a rent escalation clause and a rent holiday. In addition to the base rent, the Company was also responsible for its share of operating expenses, 
electricity and real estate taxes, in accordance with the terms of the lease agreement. Following expiration of the lease, the Company expects to operate 
virtually for the foreseeable future. 

The Company recognizes rent expense on a straight-line basis throughout the remaining term of the lease.

The following table contains a summary of the lease costs recognized and other information pertaining to the Company’s operating leases for the

Intellectual Property Licenses

Harvard and Dana-Farber Agreement

In August 2006, the Company entered into an exclusive license agreement with President and Fellows of Harvard College (“Harvard”) and Dana-
Farber  Cancer  Institute  (“DFCI”).  The  agreement  granted  the  Company  an  exclusive  worldwide  license,  with  the  right  to  sublicense,  under  specified 
patents and patent applications to develop,

obtain regulatory approval for and commercialize specified product candidates based on cell-permeating peptides. Under the agreement, the Company is 
obligated to use commercially reasonable efforts to develop and commercialize one or more licensed products and to achieve specified milestone events by 
specified dates. In connection with entering into the agreement, the Company paid an upfront license fee and issued to Harvard and DFCI shares of its 
common stock.

In February 2010, the agreement was amended and restated (the “Harvard/DFCI agreement”) under which additional patent rights were added to the 
scope of the license agreement and the annual license maintenance fees were increased. Under the Harvard/DFCI agreement, the Company is obligated to 
make aggregate milestones payments of up to $7,700 per licensed therapeutic product upon the Company’s achievement of specified clinical, regulatory 
and sales milestones with respect to such product and up to $700 per licensed diagnostic product upon the Company’s achievement of specified regulatory 
and sales milestones with respect to such product. In addition, the Company is obligated to pay royalties of low single-digit percentages on annual net sales 
of licensed products sold by the Company, its affiliates or its sublicensees. The royalties are payable on a product-by-product and country-by-country basis 
and  may  be  reduced  in  specified  circumstances.  In  addition,  the  agreement  obligates  the  Company  to  pay  a  percentage,  up  to  the  mid-twenties,  of  fees 
received  by  the  Company  in  connection  with  its  sublicense  of  the  licensed  products.  In  accordance  with  the  terms  of  the  agreement,  the  Company’s 
sublicense payment obligations may be subject to specified reductions.

The Harvard/DFCI agreement requires the Company to pay annual license maintenance fees of $110 each year. Any payments made in connection 

with the annual license maintenance fees will be credited against any royalties due.

The Company incurred license maintenance fees of $35 and $110  during  each  of  the  years  ended  December  31,  2023  and  2022,  respectively.  In 
addition, the Company did not make any milestone payments during the years ended December 31, 2023 and 2022. During the years ended December 31, 
2023 and 2022, no milestones were achieved and no liabilities for milestone payments were recorded in the Company’s consolidated financial statements. 
From  2010  through  December  31,  2023  and  December  31,  2022,  the  Company  had  made  non-refundable  cash  payments,  consisting  of  license  and 
maintenance fees, milestone payments and sublicense fees, totaling $5,153 and $5,118, respectively.

As  of  December  31,  2023,  the  Company  had  not  developed  a  commercial  product  using  the  licensed  technologies  and  no  royalties  under  the 

agreement had been paid or were due.

Under the Harvard/DFCI agreement, the Company is responsible for all patent expenses related to the prosecution and maintenance of the licensed 
patents and applications in-licensed under the agreement as well as cost reimbursement of amounts incurred for all documented patent-related expenses. 
The agreement will expire on a product-by-product and country-by-country basis upon the last to expire of any valid patent claim pertaining to licensed 
products covered under the agreement.

Umicore Agreement

In  December  2006,  the  Company  entered  into  a  license  agreement  with  Materia,  Inc.  (“Materia”),  under  which  it  was  granted  a  non-exclusive 
worldwide license, with the right to sublicense, under specified patent and patent applications to utilize Materia’s catalysts to develop, obtain regulatory 
approval for and commercialize specified peptides owned or controlled by Materia and the right to manufacture specified compositions owned or controlled 
by  Materia.  In  February  2017,  Materia  assigned  the  license  agreement  (the  “Umicore  agreement”)  to  Umicore  Precious  Metals  Chemistry  USA,  LLC 
(“Umicore”), and Umicore agreed to continue to supply the Company under the agreement.

The Company incurred license fees of $50 during each of the years ended December 31, 2023 and 2022. The Company did not make any milestone 
payments during the years ended December 31, 2023 and 2022. During the year ended December 31, 2023, no milestones were achieved and no liabilities 
for additional milestone payments were recorded in the Company’s consolidated financial statements.

The Umicore Agreement terminated in July 2023 with the expiration of the last patent the Company had licensed.

Agreement with the University of Texas Health Science Center at Tyler 

In June 2013, Lung entered into a patent and technology license agreement with the Board of Regents of the University of Texas System, or UT 
System, on behalf of University of Texas Health Science Center at Tyler, or UTHSCT. The patent and technology license agreement with UT System, or 
the  UTHSCT  Agreement,  provides  Lung  access  to  patents  and  technology  related  to  the  development  of  LTI-01  and  LTI-03.  As  part  of  the  UTHSCT 
Agreement, Lung has (i) a royalty-bearing, exclusive license under the patent rights to manufacture, distribute, and sell certain intellectual property; (ii) a 
non-exclusive license under the technology rights to manufacture, distribute and sell the licensed product; and (iii) a sublicensing right that allows Lung to 
grant sublicenses to affiliates and third parties to use the licensed product in the field of use and approved territories outlined in the UTHSCT Agreement. 
In  December  2013,  the  UTHSCT  Agreement  was  amended  and  restated  to  include  certain  patents  in  all  fields  worldwide.  In  May  2017,  the  UTHSCT 
Agreement was amended and restated to modify the specific milestone criteria. 

In consideration of the UTHSCT Agreement, Lung granted UT System (via UTHSCT and UT Horizon Fund affiliates) (i) 2,000,000 shares of Lung 
common stock and (ii) 400,000 shares of Lung non-convertible preferred stock. On February 6, 2015, UT System exchanged the 400,000 shares of Lung 
non-convertible preferred stock for 4,000,000 shares of Lung common stock. In addition, Lung agreed to pay past and ongoing patent expenses, and Lung 
owes UTHSCT sublicensing fees, assignment fees, and single digit royalties on worldwide net product sales, with fixed minimum royalty payments that 
started in 2015. 

Pursuant to the UTHSCT Agreement, Lung is required to use diligent efforts to commercialize the licensed technology as soon as commercially 

practicable, including maintaining active research and development, regulatory, marketing and sales program, all as commercially reasonable. 

The  Company  may  terminate  the  UTHSCT  Agreement  for  convenience  with  90  days’  notice.  UTHSCT  may  also  terminate  the  UTHSCT 

Agreement, but only if the Company breaches the terms of the agreement. 

Agreement with the University of Texas at Austin 

In May 2015, Lung entered into a patent license agreement with UT Austin on behalf of the UT System. This license agreement with UT Austin, or 
the UT Austin 6607 Agreement, relates to the patent rights to polypeptide therapeutics and uses thereof. Pursuant to the UT Austin 6607 Agreement Lung 
has (i) a royalty-bearing, exclusive license under the patent rights to manufacture, distribute, and sell the licensed product; and (ii) a sublicensing right that 
allows  Lung  to  grant  sublicenses  to  affiliates  and  third  parties  to  use  the  licensed  product  in  the  field  of  use  and  approved  territories  outlined  in  the 
agreement.  The  UT  Austin  6607  Agreement  was  amended  and  restated  in  January  2017,  November  2018,  and  June  2019.  The  amendments  related  to 
extension of milestone payment dates and specific terminology around the milestone achievement criteria. 

In consideration of the UT Austin 6607 Agreement, Lung agreed to pay past and ongoing patent expenses, milestone fees upon certain development 
and regulatory milestone events, annual license fees, tiered sublicense fees, assignment fees, low single digit royalties on net sales and an FDA Priority 
Review Voucher fee if Lung sells or transfers this voucher. 

Pursuant to the UT Austin 6607 Agreement, Lung is required to use diligent efforts to commercialize the licensed products, including maintaining 
active  research  and  development,  regulatory,  marketing  and  sales  program.  Moreover,  Lung  is  required  to  meet  certain  development  and  regulatory 
milestones by specific dates. 

The Company may terminate the UT Austin 6607 Agreement for convenience with 90 days’ notice. UT Austin may also terminate the UT Austin 

6607 Agreement, but only if the Company breaches the terms of the agreement. 

Agreement with Medical University of South Carolina 

F-30

 
 
In March 2016, Lung entered into a license agreement with Medical University of South Carolina Foundation for Research Development, or MUSC. 
Pursuant to this license agreement with MUSC, or the MUSC Agreement, Lung has patent rights related to protecting against lung fibrosis by up regulating 
Cav1. The MUSC Agreement granted (i) a royalty-bearing, exclusive license under the patent rights to make, use and sell the license product; and (ii) a 
sublicensing right that allows Lung to grant sublicenses to affiliates and third parties to use the licensed product in the field of use and approved territories 
outlined  in  the  agreement.  In  September  2018,  the  agreement  was  amended  and  restated  to  include  definitions  of  related  methods,  related  products  and 
related rights. 

In  consideration  of  the  MUSC  Agreement,  Lung  agreed  to  pay  a  non-refundable  license  fee,  patent  expenses,  milestone  fees  upon  certain
development,  regulatory  and  commercial  milestone  events,  sublicense  fees,  assignment  fees  and  low  single  digit  royalties  on  net  sales,  with  a  fixed 
minimum royalty payment starting in 2019 and a transaction fee upon Lung's liquidation. 

Pursuant to the MUSC Agreement, Lung is required to use diligent efforts to develop, manufacture and sell the licensed products. 

The Company may terminate the MUSC Agreement for convenience by providing a written notice to MUSC effective 90 days following the receipt 

of notice, and either party may terminate the agreement for a breach of contract. 

Agreement with Vivarta Therapeutics LLC 

In  March  2018,  Lung  entered  into  a  license  agreement  with  Vivarta  Therapeutics,  LLC,  or  Vivarta.  This  license  agreement  with  Vivarta,  or  the 
Vivarta Agreement, relates to intellectual property relating to epithelial sodium channel inhibitors and methods to treat pulmonary disease. Pursuant to the 
Vivarta Agreement Lung has (i) a royalty-bearing, exclusive license under the intellectual property rights to make, use and sell the licensed product, and (ii) 
a sublicensing right that allows Lung to grant sublicenses to affiliates and third parties to use the licensed product in the field of use and approved territories 
outlined in the agreement. 

In consideration for the Vivarta Agreement, Lung agreed to grant Vivarta a warrant to purchase an aggregate of 75,000 shares of Lung common 
stock for $0.12 per share, to pay a license fee of $10,000 upon the Vivarta Agreement effective date and $40,000 within 30 days of the receipt of a positive 
freedom  to  operate  analysis  from  legal  counsel.  Lung  also  agreed  to  pay  patent  expenses,  milestone  fees  upon  certain  development  and  regulatory 
milestone events, sublicense fees, assignment fees and low single digit royalties on net sales. 

Pursuant to the Vivarta Agreement, Lung is required to use diligent efforts to develop, manufacture and sell the licensed products. 

The Company may terminate the Vivarta Agreement for convenience by providing a written notice to Vivarta effective 90 days following the receipt 

of notice, and either party may terminate the agreement for a breach of contract. 

Manufacturing Commitments

Indemnification Agreements

In the ordinary course of business, the Company may provide indemnification of varying scope and terms to vendors, lessors, business partners and 
other  parties  with  respect  to  certain  matters  including,  but  not  limited  to,  losses  arising  out  of  breach  of  such  agreements  or  from  intellectual  property 
infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with members of its board of directors 
and  officers  that  will  require  the  Company,  among  other  things,  to  indemnify  them  against  certain  liabilities  that  may  arise  by  reason  of  their  status  or 
service as directors or officers. The maximum potential amount of future payments the Company could be required to make under these indemnification 
agreements is, in many cases, unlimited. To date, the Company has not incurred any material costs as a result of such indemnifications. The Company does 
not believe that the outcome of any claims under indemnification arrangements will have a material effect on its financial position, results of operations or 
cash flows, and it had not accrued any liabilities related to such obligations in its consolidated financial statements as of December 31, 2023 or December 
31, 2022.

16. Income Taxes

On October 31, 2023, the Company acquired, in accordance with the terms of the Lung Acquisition Agreement, the stock of Lung Therapeutics 
("Target"). In accordance with ASC 805-740-25-3, recognition of deferred tax assets and liabilities is required for substantially all temporary differences 
and acquired tax carryforwards and credits. The Company has computed estimated temporary differences and acquired tax carryforwards and credits as of 
the transaction date. The Company will not have tax basis in intangible assets recorded as part of the purchase. For accounting purposes, the intangible 
assets will not be amortized and subject to impairment review and testing. Though the tax effects may be delayed indefinitely, ASC 740-10-55-63 states 
that “deferred tax liabilities may not be eliminated or reduced because a reporting entity may be able to delay the settlement of those liabilities by delaying 
the events that would cause taxable temporary differences to reverse.” As such, the Company has recorded a deferred tax liability for the portion of the 
liability that cannot be offset with indefinite lived deferred tax assets.

The Company reported no income tax expense or benefit for the year ended December 31, 2023. The reported amount of income tax expense for the 
years differs from the amount that would result from applying domestic federal statutory tax rates to pretax losses primarily because of changes in valuation 
allowance.

A reconciliation of the U.S. federal statutory income tax rate to the Company’s effective income tax rate is as follows:

Federal statutory income tax rate

State taxes, net of federal benefit
Research and development and orphan drug tax credits
Other permanent items
Change in deferred tax asset valuation allowance
Loss of federal net operating losses due to 382

As of December 31, 2023, the Company had net operating loss carryforwards for federal and state purposes of $56,518 and $8,197, respectively. 
$2,863 of the U.S. federal tax operating loss carryforwards will begin to expire in 2036. Approximately $53,655 of the U.S. federal tax operating losses can 
be carried forward indefinitely. Of this amount, $44,420 of federal net operating losses came over from the Lung Acquisition, of which $2,863 will begin to 
expire in 2036 and the remaining $41,557 can be carried forward indefinitely. The state tax operating loss carryforwards expire beginning in 2043. As of 
December 31, 2023, the Company also had available research and development tax credit carryforwards for federal income tax purposes of $1,094, which 
begin to expire in 2035. As of December 31, 2023, the Company also had available orphan drug credit carryforwards of $6,731 for federal income tax 
purposes,  which  begin  to  expire  in  2039.  Of  this  amount,  $1,064  of  research  and  development  credit  carryforwards  and  $6,574  of  orphan  drug  credit 
carryforwards came over from the Lung Acquisition. 

On December 22, 2017, the Tax Cuts and Jobs Act (the "TCJA") was signed into law. Under the TCJA provisions, effective with tax years beginning
on or after January 1, 2022, taxpayers can no longer immediately expense research and development expenditures. Taxpayers are now required to capitalize 
and amortize these costs over 5 years for research conducted within the United States or 15 years for research conducted abroad. As a result, the Company 
capitalized $3,639 of research and development expenses for the year ended December 31, 2023 for tax purposes.

Utilization of the net operating loss carryforwards and research and development tax credit carryforwards may be subject to a substantial annual
limitation  under  Section  382  of  the  Internal  Revenue  Code  of  1986  due  to  ownership  changes  that  have  occurred  previously  or  that  could  occur  in  the 
future.  These  ownership  changes  may  limit  the  amount  of  carryforwards  that  can  be  utilized  annually  to  offset  future  taxable  income.  In  general,  an 
ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a 
corporation by more than 50% over a three-year  period.  As  of  December  31,  2023,  the  Company  has  wound  down  its  original  business  operations  and 
entered into a merger in the year, which resulted in a significant shift in ownership. The Company expects to have all prior year net operating losses and tax 
credits  of  its  legacy  business  to  be  completely  limited  going  forward  due  to  the  lack  of  continuation  in  its  legacy  business.  As  such,  all  prior  year  net 
operating  losses  and  tax  credits  have  been  written  down  to  zero  as  of  December  31,  2023.  The  remaining  net  operating  losses  and  tax  credits  as  of 
December 31, 2023 relate to post-merger activity in the year, as well as acquired attributes as part of the merger in the year. A study has been completed on 
the Target ownership shifts through December 31, 2023, and multiple ownership changes were determined. As a result, the Company has written down the 
$1,673 portion of the Target net operating losses expected to expire unutilized and include the $44,420 of remaining net operating losses and $7,638 of 
federal tax credits as part of its available attributes. As of December 31,

2023, the  total  federal  net  operating  losses  are  $56,518  and  federal  research  and  development  tax  credits  are  $7,825,  which  could  be  subject  to  future 
limitations under these rules.

The  Company  has  evaluated  the  positive  and  negative  evidence  bearing  upon  its  ability  to  realize  the  deferred  tax  assets.  Management  has 
considered the Company’s cumulative net losses and its lack of commercialization of any products or generation of any revenue from product sales since 
inception  and  has  concluded  that  it  is  more  likely  than  not  that  the  Company  will  not  realize  the  benefits  of  the  deferred  tax  assets.  The  Company 
maintained a full valuation allowance on its net deferred tax assets as of December 31, 2023. Management reevaluates the positive and negative evidence at 
each reporting period. The decrease in the valuation allowance relates primarily to the deferred tax liability recognized as a result of the transaction as well 
as the reduction in prior year deferred tax assets due to Section 382 limitations. The increase in the valuation allowance for deferred tax assets during the 
year ended December 31, 2023 related primarily to an increase in net operating loss carryforwards. Changes in the valuation allowance were as follows:

Valuation allowance at beginning of year

Decreases/(increases) recorded to income tax provision
Increases recorded to invested capital

Valuation allowance at end of year

The Company has not recorded any amounts for unrecognized tax benefits as of December 31, 2023 or 2022. 

The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal course of business, the Company 
is subject to examination by federal and state jurisdictions, where applicable. There are currently no pending tax examinations. The Company’s tax years 
are still open under statute from 2019 to the present. Earlier years may be examined to the extent that tax credit or net operating loss carryforwards are used 
in future periods. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision. As of December 31, 
2023 and 2022, the Company had no accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s 
consolidated statements of operations and comprehensive loss. 

17. Related Party Transactions 

Immediately following the closing of the Lung Acquisition, the Company entered into the Purchase Agreement with a group of accredited investors 
led  by  Bios  Partners,  the  majority  stockholder  of  Lung  prior  to  the  closing  of  Lung  Acquisition,  and  including  Nantahala  Capital,  as  well  as  additional 
undisclosed  investors,  pursuant  to  which  the  Company  issued  and  sold  (i)  an  aggregate  of  4,707  shares  of  Series  X  Preferred  Stock,  and  (ii)  up  to  an 
aggregate  of  2,353,500  Warrant  Shares,  as  described  in  the  Note  3,  which  included  the  conversion  of  convertible  promissory  notes  in  the  aggregate 
principal amount of $1,553 issued by Lung to Bios Partners prior to the closing of the acquisition at a 10% discount to the per share price of Series X 
Preferred Stock. The Financing closed on November 2, 2023.

18. Subsequent Event

On February 28, 2024, the Company held its 2023 annual meeting of stockholders (the “2023 Annual Meeting”) at which the stockholders of the 
Company approved an amendment (the “Plan Amendment”) to the Aileron’s 2021 Plan to increase the number of shares of common stock issuable under 
the 2021 Plan by 3,000,000 shares to 3,840,254. On January 17, 2024, upon the recommendation of the compensation committee and subject to stockholder 
approval, the Company’s Board of Directors adopted the Plan Amendment. Other than increasing the number of shares issuable under the 2021 Plan, the 
Plan  Amendment  does  not  make  any  changes  to  the  2021  Plan.  The  material  terms  of  the  2021  Plan  are  described  in  the  Company’s  definitive  proxy 
statement for the 2023 Annual Meeting filed with the Securities and Exchange Commission on January 29, 2024 (the “Proxy Statement”).

At  the  2023  Annual  Meeting,  the  Company’s  stockholders  approved  an  amendment  to  the  Company’s  Restated  Certificate  of  Incorporation,  as 
amended, to increase the number of authorized shares of common stock of the Company from 45,000,000 to 100,000,000 shares. The Company filed the 
Certificate of Amendment to implement 

F-34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
the increase in the number of authorized shares, which was effective upon filing, with the Secretary of State of the State of Delaware on February 28, 2024. 
The additional shares of common stock authorized by the Certificate of Amendment have rights identical to the Company’s currently outstanding Common 
Stock.

At the 2023 Annual Meeting, the Company’s stockholders also approved the issuance, in accordance with Nasdaq Listing Rule 5635(a), of shares of 
common stock, upon conversion of the Company's outstanding Series X Preferred Stock. Following approval of the conversion of outstanding Series X 
Preferred  Stock,  the  Company  had  29,495,512  shares  of  common  stock  issued  and  outstanding  on  a  pro  forma  basis,  which  gives  effect  to  the  full 
conversion of the Series X Preferred Stock as of the date of the 2023 Annual Meeting, without regard to beneficial ownership limitations that may limit the 
ability  of  certain  holders  of  Series  X  Preferred  Stock  to  convert  such  shares  to  common  stock  as  such  time.  On  March  5,  2024,  based  upon  existing 
beneficial ownership limitations, 12,087 shares of Series X Preferred Stock were automatically converted into 12,087,000 shares of common stock. The 
remaining  approximately  12,523  shares  of  Series  X  Preferred  Stock  (which  are  convertible  into  12,523,000  shares  of  common  stock)  will  remain 
convertible at the option of the holder thereof, subject to certain beneficial ownership limitations.

On  February  29,  2024,  the  Company  received  a  letter  from  the  Listing  Qualifications  Department  of  the  Nasdaq  Stock  Market  notifying  the 
Company  that  it  has  regained  compliance  with  the  annual  meeting  requirement  for  continued  listing  on  the  Nasdaq  Capital  Market  set  forth  in  Nasdaq 
Listing Rule 5620.

On March 11, 2024, the Company and Manuel C. Alves-Aivado, M.D., Ph.D., agreed that his employment with the Company would cease and he 
would resign from his position as Chief Executive Officer of the Company, effective as of March 11, 2024 (the “Separation Date”). Dr. Aivado will remain 
a member of the Company’s Board. Dr. Aivado’s resignation from the Company was not the result of any disagreement with the Company on any matter 
relating to its operations, policies or practices.

In connection with Dr. Aivado’s separation from the Company, and in accordance with the severance agreement, dated as of September 6, 2018, 
between  the  Company  and  Dr.  Aivado,  Dr.  Aivado  is  entitled  to  receive  his  base  salary  for  eighteen  months  of  $881  following  the  separation  date, 
payments  on  Dr.  Aivado’s  behalf  of  the  monthly  premiums  for  medical  insurance  coverage  under  COBRA  until  the  earlier  of  the  date  that  is  eighteen 
months  following  the  separation  date  or  the  date  on  which  Dr.  Aivado  becomes  eligible  to  receive  group  health  insurance  coverage  through  another 
employer, a lump sum payment of $441 equal to one and one-half times Dr. Aivado’s target bonus for the 2024 calendar year, and acceleration in full of the 
vesting  of  any  unvested  equity  awards.  Dr.  Aivado’s  receipt  of  these  post-separation  benefits  under  the  severance  agreement  is  conditioned  upon  his 
execution of a severance and release of claims agreement with the Company.

DESCRIPTION OF SECURITIES REGISTERED UNDER SECTION 12 OF THE EXCHANGE ACT OF 1934, AS AMENDED

The following description of the common stock, par value $0.001 per share, of Aileron Therapeutics, Inc. (“us,” “our,” “we” or the “Company”), which is 
the  only  security  of  the  Company  registered  under  Section  12  of  the  Securities  Exchange  Act  of  1934,  as  amended,  summarizes  certain  information 
regarding  the  common  stock  in  our  restated  certificate  of  incorporation,  as  amended,  our  amended  and  restated  bylaws  and  applicable  provisions  of 
Delaware  corporate  law,  and  is  qualified  by  reference  to  our  restated  certificate  of  incorporation,  as  amended,  certificate  of  amendment  of  our  restated 
certificate of incorporation, dated as of November 10, 2022, certificate of amendment of our restated certificate of incorporation, dated as of February 28, 
2024,  amended  and  restated  bylaws,  and  certificate  of  designation  of  our  Series  X  Non-Voting  Convertible  Preferred  Stock,  which  are  incorporated  by 
reference as Exhibit 3.1, 3.2, 3.3, 3.4, and 3.5, respectively, to the Annual Report on Form 10-K of which this exhibit is a part.

Authorized Capital Stock

Our  authorized  capital  stock  consists  of  100,000,000  shares  of  common  stock,  par  value  $0.001  per  share  (“Common  Stock”),  and  5,000,000  shares  of 
preferred stock, par value $0.001 per share, of which 24,847 shares have been designated as Series X Non-Voting Convertible Preferred Stock, par value 
$0.001 per share (“Series X Preferred Stock”).

Common Stock 

Voting Rights. Holders of Common Stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have 
cumulative voting rights. An election of directors by our stockholders will be determined by a plurality of the votes cast by the stockholders entitled to vote 
on the election. Any matter other than the election of directors to be voted upon by the stockholders at such meeting will be decided by the affirmative vote 
of our stockholders having a majority in voting power of the votes cast by the stockholders present or represented and voting on such matter, except when a 
different vote is required by law, our certificate of incorporation or our bylaws. 

Dividends. Holders of Common Stock are entitled to receive proportionately any dividends as may be declared and paid on the common stock from funds 
lawfully available therefor as and when determined by our board of directors, subject to any preferential dividend rights of outstanding preferred stock. 

Liquidation and Dissolution. In the event of our liquidation or dissolution, the holders of Common Stock are entitled to receive proportionately all assets 
available for distribution to stockholders after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. 

Other Rights.  Holders  of  Common  Stock  have  no  preemptive,  subscription,  redemption  or  conversion  rights.  The  rights,  preferences  and  privileges  of 
holders of Common Stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may 
designate and issue in the future. Outstanding shares of Common Stock are non-assessable. Holders of Common Stock are not, and will not be, subject to 
any liability as stockholders.

Preferred Stock 

Under the terms of our certificate of incorporation, our board of directors is authorized to issue shares of preferred stock in one or more series without 
stockholder  approval.  Our  board  of  directors  has  the  discretion  to  determine  the  rights,  preferences,  privileges  and  restrictions,  including  voting  rights, 
dividend  rights,  conversion  rights,  redemption  privileges  and  liquidation  preferences,  of  each  series  of  preferred  stock.  The  issuance  of  preferred  stock 
could impede the completion of a merger, tender offer or other takeover attempt.

Series X Non-Voting Convertible Preferred Stock

As  reported  on  a  current  report  on  Form  8-K  filed  with  the  Securities  and  Exchange  Commission  on  October  31,  2023,  the  Company  acquired  Lung 
Therapeutics,  Inc.  (“Lung”),  which  acquisition  closed  on  October  31,  2023  (the  “Lung  Acquisition.”).  In  connection  with  the  Lung  Acquisition,  the 
Company issued newly-designated shares of Series X Preferred Stock.

Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Preferred Stock equal, on an as-if-converted-to-Common-Stock 
basis, and in the same form as dividends actually paid on shares of the Common Stock. Except as otherwise required by law, the Series X Preferred Stock 
does not have voting rights. However, as 

1

long as any shares of Series X Preferred Stock are outstanding, we will not, without the affirmative vote of the holders of a majority of the then outstanding 
shares  of  the  Series  X  Preferred  Stock,  (i)  alter  or  change  adversely  the  powers,  preferences  or  rights  given  to  the  Series  X  Preferred  Stock  or  alter  or 
amend the Certificate of Designation of Preferences, Rights and Limitations of Series X Preferred Stock (the “Certificate of Designation”), amend or repeal 
any  provision  of,  or  add  any  provision  to,  the  Certificate  of  Incorporation  or  by-laws  of  the  Company,  or  file  any  articles  of  amendment,  certificate  of 
designations, preferences, limitations and relative rights of any series of preferred stock, if such action would adversely alter or change the preferences, 
rights, privileges or powers of, or restrictions provided for the benefit of the Series X Preferred Stock, (ii) issue further shares of Series X Preferred Stock 
or  increase  or  decrease  (other  than  by  conversion)  the  number  of  authorized  shares  of  Series  X  Preferred  Stock,  or  (iii)  enter  into  any  agreement  with 
respect to any of the foregoing. The Series X Preferred Stock does not have a preference upon any liquidation, dissolution or winding-up of the Company.

Each share of Series X Preferred Stock is convertible at any time at the option of the holder thereof, into 1,000 shares of Common Stock, subject to certain 
beneficial ownership limitations, including that a holder of Series X Preferred Stock is prohibited from converting shares of Series X Preferred Stock into 
shares of Common Stock if, as a result of such conversion, such holder (together with its affiliates and any other persons acting as a group together with the 
holder or any of its affiliates) would beneficially own more than a specified percentage (to be initially set at 19.99% and thereafter adjusted by the holder to 
a number not to exceed 19.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion.

Common Stock Issuable Upon Exercise of Warrants

PIPE Warrants

In November 2023 in connection with a financing, we issued warrants (“PIPE Warrants”) to purchase up to an aggregate of 2,353,500 shares of Common 
Stock (“PIPE Warrant Shares”). The exercise price of the PIPE Warrants is $4.89 per share, subject to certain price and share adjustments, including for 
stock splits, stock dividends, recapitalizations, subdivisions, combinations, reclassifications, noncash distributions and cash dividends. The PIPE Warrants 
will be exercisable any time after May 2, 2024 and will remain exercisable until May 2, 2027. Payment for PIPE Warrant Shares upon exercise of the PIPE 
Warrants may be (i) in cash or (ii) in the event that there is no registration statement available for the resale of PIPE Warrant Shares, by cashless exercise.

Under the terms of the PIPE Warrants, we shall not effect the exercise of any portion of any PIPE Warrant, and a holder shall not have the right to exercise 
any portion of any Warrant, to the extent that after giving effect to such exercise, the holder (together with its affiliates and any other persons acting as a 
group together with the holder or any of its affiliates), would beneficially own in excess of a percentage elected by the holder up to 19.99% of the number 
of shares of Common Stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with 
the terms of the PIPE Warrants. However, any holder may, upon written notice to us, increase or decrease such percentage to any other percentage not in 
excess  of  19.99%;  provided  that  any  increase  or  decrease  in  such  percentage  will  not  be  effective  until  61  days  after  such  notice  is  delivered  to  the 
Company.

Lung Warrants

In connection with the Lung Acquisition, the Company assumed all outstanding warrants exercisable for Lung common stock (the “Lung Warrants”), each 
becoming a warrant to purchase Common Stock, subject to adjustment pursuant to the terms of that certain Agreement and Plan of Merger, dated October 
31, 2023, by and among the Company, AT Merger Sub I, Inc., AT Merger Sub II, LLC, and Lung.

The Lung Warrants are exercisable for up to an aggregate of 726,437 shares of Common Stock. The weighted average exercise price of the Lung Warrants 
is $5.66 per share, subject to customary adjustments. The Lung Warrants are currently exercisable. Certain of the Lung Warrants remain exercisable until 
November 2027 and the remainder remain exercisable until May 2029.

Provisions of Our Certificate of Incorporation and By-laws and the DGCL That May Have Anti-Takeover Effects

The DGCL contains, and our certificate of incorporation and by-laws contain, provisions that could have the effect of delaying, deferring or discouraging 
another party from acquiring control of us. These provisions, which are 

2

 
summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage 
persons seeking to acquire control of us to first negotiate with our board of directors. 

Staggered Board; Removal of Directors. Our certificate of incorporation and by-laws divide our board of directors into three classes with staggered three-
year terms. In addition, a director may be removed only for cause and only by the affirmative vote of the holders of at least 75% of the votes that all of our 
stockholders would be entitled to cast in an annual election of directors. Any vacancy on our board of directors, including a vacancy resulting from an 
enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. The classification of our board of directors 
and the limitations on the removal of directors and filling of vacancies could make it more difficult for a third party to acquire, or discourage a third party 
from seeking to acquire, control of our company. 

Stockholder Action by Written Consent; Special Meetings. Our certificate of incorporation provides that any action required or permitted to be taken by our 
stockholders must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. 
Our certificate of incorporation and by-laws also provide that, except as otherwise required by law, special meetings of our stockholders can only be called 
by the chairman of our board of directors, our chief executive officer or our board of directors. 

Advance Notice Requirements for Stockholder Proposals. Our by-laws establish an advance notice procedure for stockholder proposals to be brought before 
an annual meeting of stockholders, including proposed nominations of persons for election to our board of directors. Stockholders at an annual meeting 
may consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or 
by a stockholder of record on the record date for the meeting who is entitled to vote at the meeting and who has delivered timely written notice in proper 
form to our secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying until the 
next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities. 

Delaware Business Combination Statute. We are subject to Section 203 of the DGCL. Subject to certain exceptions, Section 203 prevents a publicly held 
Delaware  corporation  from  engaging  in  a  “business  combination”  with  any  “interested  stockholder”  for  three  years  following  the  date  that  the  person 
became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the business 
combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the 
“interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any entity or person beneficially owning 
15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person. 

Amendment of Certificate of Incorporation and By-laws. The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote 
on any matter is required to amend a corporation’s certificate of incorporation or by-laws, unless a corporation’s certificate of incorporation or by-laws, as 
the case may be, requires a greater percentage. Our by-laws may be amended or repealed by a majority vote of our board of directors or by the affirmative 
vote of the holders of at least 75% of the votes that all of our stockholders would be entitled to cast in any annual election of directors. In addition, the 
affirmative  vote  of  the  holders  of  at  least  75%  of  the  votes  that  all  of  our  stockholders  would  be  entitled  to  cast  in  any  annual  election  of  directors  is 
required to amend or repeal or to adopt any provisions inconsistent with any of the provisions of our certificate of incorporation described above under “-
Staggered Board; Removal of Directors” and “-Stockholder Action by Written Consent; Special Meetings.” 

Exclusive Forum Selection. Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of 
Chancery of the State of Delaware (or if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) shall be the 
sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of a fiduciary duty 
owed by any of our directors, officers or employees to our company or stockholders, (3) any action asserting a claim against us arising pursuant to any 
provision of the DGCL or our certificate of incorporation or by-laws, or (4) any action asserting a claim against us governed by the internal affairs doctrine. 
We do not expect this choice of forum provision will apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended, 
the Exchange Act of 1934, as amended, or any other claim for which federal courts have exclusive jurisdiction. Although our certificate of incorporation 
contains the choice of forum provision described above, it is possible that a court could rule that such a provision is inapplicable for a particular claim or 
action or that such provision is unenforceable.

AILERON THERAPEUTICS, INC.

2021 STOCK INCENTIVE PLAN

1.  Purpose 

The purpose of this 2021 Stock Incentive Plan (the “Plan”) of Aileron Therapeutics, Inc., a Delaware corporation (the “Company”), is to advance the 
interests of the Company’s stockholders by enhancing the Company’s ability to attract, retain and motivate persons who are expected to make important 
contributions to the Company and by providing such persons with equity ownership opportunities and performance-based incentives that are intended to 
better align the interests of such persons with those of the Company’s stockholders. Except where the context otherwise requires, the term “Company” shall 
include any of the Company’s present or future parent or subsidiary corporations as defined in Sections 424(e) or (f) of the Internal Revenue Code of 1986, 
as amended, and any regulations thereunder (the “Code”) and any other business venture (including, without limitation, joint venture or limited liability 
company) in which the Company has a controlling interest, as determined by the Board of Directors of the Company (the “Board”).

2.  Eligibility 

All of the Company’s employees, officers and directors, as well as consultants and advisors to the Company (as the terms consultants and advisors are 
defined and interpreted for purposes of Form S-8 under the Securities Act of 1933, as amended (the “Securities Act”), or any successor form) are eligible to 
be granted Awards (as defined below) under the Plan. Each person who is granted an Award under the Plan is deemed a “Participant.” The Plan provides 
for the following types of awards, each of which is referred to as an “Award”: Options (as defined in Section 5), SARs (as defined in Section 6), Restricted 
Stock (as defined in Section 7), RSUs (as defined in Section 7), Other Stock-Based Awards (as defined in Section 8) and Cash-Based Awards (as defined in 
Section 8). Except as otherwise provided by the Plan, each Award may be made alone or in addition or in relation to any other Award. The terms of each 
Award need not be identical, and the Board need not treat Participants uniformly.

3.  Administration and Delegation 

(a) Administration by Board of Directors. The Plan will be administered by the Board. The Board shall have authority to grant Awards and to adopt, amend 
and repeal such administrative rules, guidelines and practices relating to the Plan as it shall deem advisable. The Board may construe and interpret the terms 
of the Plan and any Award agreements entered into under the Plan. The Board may correct any defect, supply any omission or reconcile any inconsistency 
in the Plan or any Award. All actions and decisions by the Board with respect to the Plan and any Awards shall be made in the Board’s discretion and shall 
be final and binding on all persons having or claiming any interest in the Plan or in any Award.

(b) Appointment of Committees. To the extent permitted by applicable law, the Board may delegate any or all of its powers under the Plan to one or more 
committees or subcommittees of the Board (a “Committee”). All references in the Plan to the “Board” shall mean the Board or a Committee of the Board 
or the officers referred to in Section 3(c) to the extent that the Board’s powers or authority under the Plan have been delegated to such Committee or 
officers.

(c) Delegation to Officers. Subject to any requirements of applicable law (including as applicable Sections 152 and 157(c) of the General Corporation Law 
of the State of Delaware), the Board may delegate to one or more officers of the Company the power to grant Awards (subject to any limitations under the 
Plan) to employees or officers of the Company and to exercise such other powers under the Plan as the Board may determine, provided that the Board shall 
fix the terms of Awards to be granted by such officers, the maximum number of shares subject to Awards that the officers may grant, and the time period in 
which such Awards may be granted; and provided further, that no officer shall be authorized to grant Awards to any “executive officer” of the Company (as 
defined by Rule 3b-7 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) or to any “officer” of the Company (as defined by 
Rule 16a-1(f) under the Exchange Act).

 
 
4.  Stock Available for Awards 

(a) Number of Shares; Share Counting.

(1) Authorized Number of Shares. Subject to adjustment under Section 10, Awards may be made under the Plan (any or all of which Awards may be in the 
form of Incentive Stock Options (as defined in Section 5(b)) for up to such number of shares of common stock, $0.001 par value per share, of the Company 
(the “Common Stock”) as is equal to the sum of:

(A) 3,625,000 shares of Common Stock (reduced by the number of shares subject to awards granted under the Company’s 2017 Stock Incentive Plan 
between April 15, 2021 and June 15, 2021); plus

(B) such additional number of shares of Common Stock (up to 314,006 shares) as is equal to the number of shares of Common Stock subject to awards 
granted under the Company’s 2017 Stock Incentive Plan, the Company’s 2016 Stock Incentive Plan and the Company’s 2006 Stock Incentive Plan which 
awards expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by the Company at their original issuance price pursuant to a 
contractual repurchase right (subject, however, in the case of Incentive Stock Options to any limitations of the Code).

Shares of Common Stock issued under the Plan may consist in whole or in part of authorized but unissued shares or treasury shares.

(2) Share Counting. For purposes of counting the number of shares available for the grant of Awards under the Plan under Section 4(a)(1):

(A) all shares of Common Stock covered by SARs shall be counted against the number of shares available for the grant of Awards under the Plan; provided, 
however, that (i) SARs that may be settled only in cash shall not be so counted and (ii) if the Company grants an SAR in tandem with an Option for the 
same number of shares of Common Stock and provides that only one such Award may be exercised (a “Tandem SAR”), only the shares covered by the 
Option, and not the shares covered by the Tandem SAR, shall be so counted, and the expiration of one in connection with the other’s exercise will not 
restore shares to the Plan;

(B) if any Award (i) expires or is terminated, surrendered or cancelled without having been fully exercised or is forfeited in whole or in part (including as 
the result of shares of Common Stock subject to such Award being repurchased by the Company at the original issuance price pursuant to a contractual 
repurchase right) or (ii) results in any Common Stock not being issued (including as a result of an SAR that was settleable either in cash or in stock actually 
being settled in cash), the unused Common Stock covered by such Award shall again be available for the grant of Awards; provided, however, that (1) in the 
case of Incentive Stock Options, the foregoing shall be subject to any limitations under the Code, (2) in the case of the exercise of an SAR, the number of 
shares counted against the shares available under the Plan shall be the full number of shares subject to the SAR multiplied by the percentage of the SAR 
actually exercised, regardless of the number of shares actually used to settle such SAR upon exercise and (3) the shares covered by a Tandem SAR shall not 
again become available for grant upon the expiration or termination of such Tandem SAR;

(C) to the extent that an RSU may be settled solely in cash, no shares shall be counted against the limit on the shares available for grant of Awards under 
the Plan;

(D) shares of Common Stock delivered (by actual delivery, attestation, or net exercise) to the Company by a Participant to (i) purchase shares of Common 
Stock upon the exercise of an Award or (ii) satisfy tax withholding obligations with respect to Awards (including shares retained from the Award creating 
the tax obligation) shall not be added back to the number of shares available for the future grant of Awards; and

(E) shares of Common Stock repurchased by the Company on the open market using the proceeds from the exercise of an Award shall not increase the 
number of shares available for future grant of Awards.

 
 
(b) Limit on Awards to Non-Employee Directors. The maximum aggregate amount of cash and equity value (calculated based on grant date fair value for 
financial reporting purposes) of Awards granted in any calendar year to any individual non-employee director in his or her capacity as a non-employee 
director shall not exceed $750,000; provided, however, that such maximum aggregate amount shall not exceed $1,000,000 in any calendar year for any 
individual non-employee director in such non-employee director’s initial year of service; and provided, further, however, that fees paid by the Company on 
behalf of any non-employee director in connection with regulatory compliance and any amounts paid to a non-employee director as reimbursement of an 
expense shall not count against the foregoing limit. The Board may make additional exceptions to this limit for individual non-employee directors in 
extraordinary circumstances, as the Board may determine in its discretion, provided that the non- employee director receiving such additional compensation 
may not participate in the decision to award such compensation. For the avoidance of doubt, this limitation shall not apply to cash or Awards granted to the 
non-employee director in his or her capacity as an advisor or consultant to the Company.

(c) Substitute Awards. In connection with a merger or consolidation of an entity with the Company or the acquisition by the Company of property or stock 
of an entity, the Board may grant Awards in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof. 
Substitute Awards may be granted on such terms as the Board deems appropriate in the circumstances, notwithstanding any limitations on Awards 
contained in the Plan or any sublimits contained in the Plan. Substitute Awards shall not count against the overall share limit set forth in Section 4(a)(1), 
except as may be required by reason of Section 422 and related provisions of the Code.

5.  Stock Options 

(a) General. The Board may grant options to purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be 
covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option, including conditions 
relating to applicable federal or state securities laws, as the Board considers necessary or advisable.

(b) Incentive Stock Options. An Option that the Board intends to be an “incentive stock option” as defined in Section 422 of the Code (an “Incentive Stock 
Option”) shall only be granted to employees of Aileron Therapeutics, Inc., any of Aileron Therapeutics, Inc.’s present or future parent or subsidiary 
corporations as defined in Sections 424(e) or (f) of the Code, and any other entities the employees of which are eligible to receive Incentive Stock Options 
under the Code, and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. An Option that is not intended 
to be an Incentive Stock Option shall be designated a “Nonstatutory Stock Option.” The Company shall have no liability to a Participant, or any other 
person, if an Option (or any part thereof) that is intended to be an Incentive Stock Option is not an Incentive Stock Option or if the Company converts an 
Incentive Stock Option to a Nonstatutory Stock Option.

(c) Exercise Price. The Board shall establish the exercise price of each Option or the formula by which such exercise price will be determined. The exercise 
price shall be specified in the applicable Option agreement. The exercise price shall be not less than 100% of the Grant Date Fair Market Value (as defined 
below) of the Common Stock on the date the Option is granted; provided that if the Board approves the grant of an Option with an exercise price to be 
determined on a future date, the exercise price shall be not less than 100% of the Grant Date Fair Market Value on such future date. “Grant Date Fair 
Market Value” of a share of Common Stock for purposes of the Plan will be determined as follows:

(1) if the Common Stock trades on a national securities exchange, the closing sale price (for the primary trading session) on the date of grant; or

(2) if the Common Stock does not trade on any such exchange, the average of the closing bid and asked prices on the date of grant as reported by an over-
the-counter marketplace designated by the Board; or

(3) if the Common Stock is not publicly traded, the Board will determine the Grant Date Fair Market Value for purposes of the Plan using any measure of 
value it determines to be appropriate (including, as it considers appropriate, relying on appraisals) in a manner consistent with the valuation principles 
under Code Section 409A, except as the Board may expressly determine otherwise.

 
 
For any date that is not a trading day, the Grant Date Fair Market Value of a share of Common Stock for such date will be determined by using the closing 
sale price or average of the bid and asked prices, as appropriate, for the immediately preceding trading day and with the timing in the formulas above 
adjusted accordingly. The Board can substitute a particular time of day or other measure of “closing sale price” or “bid and asked prices” if appropriate 
because of exchange or market procedures or can, in its sole discretion, use weighted averages either on a daily basis or such longer period as complies 
with Code Section 409A.

The Board has sole discretion to determine the Grant Date Fair Market Value for purposes of the Plan, and all Awards are conditioned on the Participant’s 
agreement that the Board’s determination is conclusive and binding even though others might make a different determination.

(d) Duration of Options. Each Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable 
Option agreement; provided, however, that no Option will be granted with a term in excess of 10 years.

(e) Exercise of Options. Options may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the 
Company, together with payment in full (in the manner specified in Section 5(f)) of the exercise price for the number of shares for which the Option is 
exercised. Shares of Common Stock subject to the Option will be delivered by the Company as soon as practicable following exercise.

(f) Payment Upon Exercise. Common Stock purchased upon the exercise of an Option granted under the Plan shall be paid for as follows:

(1) in cash or by check, payable to the order of the Company;

(2) except as may otherwise be provided in the applicable Option agreement or approved by the Board, by (i) delivery of an irrevocable and unconditional 
undertaking by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price and any required tax withholding or (ii) 
delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the 
Company cash or a check sufficient to pay the exercise price and any required tax withholding;

(3) to the extent provided for in the applicable Option agreement or approved by the Board, by delivery (either by actual delivery or attestation) of shares of 
Common Stock owned by the Participant valued at their fair market value (valued in the manner determined by (or in a manner approved by) the Board), 
provided (i) such method of payment is then permitted under applicable law, (ii) such Common Stock, if acquired directly from the Company, was owned 
by the Participant for such minimum period of time, if any, as may be established by the Board and (iii) such Common Stock is not subject to any 
repurchase, forfeiture, unfulfilled vesting or other similar requirements;

(4) to the extent provided for in the applicable Nonstatutory Stock Option agreement or approved by the Board, by delivery of a notice of “net exercise” to 
the Company, as a result of which the Participant would receive (i) the number of shares underlying the portion of the Option being exercised, less (ii) such 
number of shares as is equal to (A) the aggregate exercise price for the portion of the Option being exercised divided by (B) the fair market value of the 
Common Stock (valued in the manner determined by (or in a manner approved by) the Board) on the date of exercise;

(5) to the extent permitted by applicable law and provided for in the applicable Option agreement or approved by the Board, by payment of such other 
lawful consideration as the Board may determine; or

(6) by any combination of the above permitted forms of payment.

(g) Limitation on Repricing. Unless such action is approved by the Company’s stockholders, the Company may not (except as provided for under Section 
10): (1) amend any outstanding Option granted under the Plan to provide an exercise price per share that is lower than the then-current exercise price per 
share of such outstanding Option, (2) cancel any outstanding option (whether or not granted under the Plan) and grant in substitution therefor new Awards 

 
 
under the Plan (other than Awards granted pursuant to Section 4(c)) covering the same or a different number of shares of Common Stock and having an 
exercise price per share lower than the then-current exercise price per share of the cancelled option, (3) cancel in exchange for a cash payment any 
outstanding Option with an exercise price per share above the then-current fair market value of the Common Stock (valued in the manner determined by (or 
in a manner approved by) the Board), or (4) take any other action under the Plan that constitutes a “repricing” within the meaning of the rules of the Nasdaq 
Stock Market (“Nasdaq”).

(h) No Reload Options. No Option granted under the Plan shall contain any provision entitling the Participant to the automatic grant of additional Options 
in connection with any exercise of the original Option.

(i) No Dividend Equivalents. No Option shall provide for the payment or accrual of dividend equivalents.

6.  Stock Appreciation Rights 

(a) General. The Board may grant Awards consisting of stock appreciation rights (“SARs”) entitling the holder, upon exercise, to receive an amount of 
Common Stock or cash or a combination thereof (such form to be determined by the Board) determined by reference to appreciation, from and after the 
date of grant, in the fair market value of a share of Common Stock (valued in the manner determined by (or in a manner approved by) the Board) over the 
measurement price established pursuant to Section 6(b). The date as of which such appreciation is determined shall be the exercise date.

(b) Measurement Price. The Board shall establish the measurement price of each SAR and specify it in the applicable SAR agreement. The measurement 
price shall not be less than 100% of the Grant Date Fair Market Value of the Common Stock on the date the SAR is granted; provided that if the Board 
approves the grant of an SAR effective as of a future date, the measurement price shall be not less than 100% of the Grant Date Fair Market Value on such 
future date.

(c) Duration of SARs. Each SAR shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable 
SAR agreement; provided, however, that no SAR will be granted with a term in excess of 10 years.

(d) Exercise of SARs. SARs may be exercised by delivery to the Company of a notice of exercise in a form (which may be electronic) approved by the 
Company, together with any other documents required by the Board.

(e) Limitation on Repricing. Unless such action is approved by the Company’s stockholders, the Company may not (except as provided for under Section 
10): (1) amend any outstanding SAR granted under the Plan to provide a measurement price per share that is lower than the then-current measurement price 
per share of such outstanding SAR, (2) cancel any outstanding SAR (whether or not granted under the Plan) and grant in substitution therefor new Awards 
under the Plan (other than Awards granted pursuant to Section 4(c)) covering the same or a different number of shares of Common Stock and having a 
measurement price per share lower than the then-current measurement price per share of the cancelled SAR, (3) cancel in exchange for a cash payment any 
outstanding SAR with a measurement price per share above the then-current fair market value of the Common Stock (valued in the manner determined by 
(or in a manner approved by) the Board), or (4) take any other action under the Plan that constitutes a “repricing” within the meaning of the rules of 
Nadsaq.

(f) No Reload SARs. No SAR granted under the Plan shall contain any provision entitling the Participant to the automatic grant of additional SARs in 
connection with any exercise of the original SAR.

(g) No Dividend Equivalents. No SAR shall provide for the payment or accrual of dividend equivalents.

7.  Restricted Stock; RSUs 

(a) General. The Board may grant Awards entitling recipients to acquire shares of Common Stock (“Restricted Stock”), subject to the right of the Company 
to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) from 
the recipient in the event that 

 
 
 
conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the 
Board for such Award. The Board may also grant Awards entitling the recipient to receive shares of Common Stock or cash to be delivered at the time such 
Award vests (“RSUs”).

(b) Terms and Conditions for Restricted Stock and RSUs. The Board shall determine the terms and conditions of Restricted Stock and RSUs, including the 
conditions for vesting and repurchase (or forfeiture) and the issue price, if any.

(c) Additional Provisions Relating to Restricted Stock.

(1) Dividends. Any dividends (whether paid in cash, stock or property) declared and paid by the Company with respect to shares of Restricted Stock 
(“Unvested Dividends”) shall be paid to the Participant only if and when such shares become free from the restrictions on transferability and forfeitability 
that apply to such shares. Each payment of Unvested Dividends, once payable, will be made no later than the end of the calendar year in which the 
dividends are paid to stockholders of that class of stock or, if later, the 15th day of the third month following the lapsing of the restrictions on transferability 
and the forfeitability provisions applicable to the underlying shares of Restricted Stock. No interest will be paid on Unvested Dividends.

(2) Stock Certificates. The Company may require that any stock certificates issued in respect of shares of Restricted Stock, as well as dividends or 
distributions paid on such Restricted Stock, shall be deposited in escrow by the Participant, together with a stock power endorsed in blank, with the 
Company (or its designee). At the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer 
subject to such restrictions to the Participant or if the Participant has died, to his or her Designated Beneficiary. “Designated Beneficiary” means (i) the 
beneficiary designated, in a manner determined by the Board, by a Participant to receive amounts due or exercise rights of the Participant in the event of the 
Participant’s death or (ii) in the absence of an effective designation by a Participant, the Participant’s estate.

(d) Additional Provisions Relating to RSUs.

(1) Settlement. Upon the vesting of and/or lapsing of any other restrictions (i.e., settlement) with respect to each RSU, the Participant shall be entitled to 
receive from the Company the number of shares of Common Stock specified in the Award agreement or (if so provided in the applicable Award agreement 
or otherwise determined by the Board) an amount of cash equal to the fair market value (valued in the manner determined by (or in a manner approved by) 
the Board) of such number of shares or a combination thereof. The Board may provide that settlement of RSUs shall be deferred, on a mandatory basis or at 
the election of the Participant, in a manner that complies with Section 409A of the Code or any successor provision thereto, and the regulations thereunder 
(“Section 409A”).

(2) Voting Rights. A Participant shall have no voting rights with respect to any RSUs.

(3) Dividend Equivalents. The Award agreement for RSUs may provide Participants with the right to receive an amount equal to any dividends or other 
distributions declared and paid on an equal number of outstanding shares of Common Stock (“Dividend Equivalents”). Dividend Equivalents may be paid 
currently or credited to an account for the Participant and may be settled in cash and/or shares of Common Stock, in each case to the extent provided in the 
Award agreement, and shall be subject to the same restrictions on transfer and forfeitability as the RSUs with respect to which such Dividend Equivalents 
are paid. No interest will be paid on Dividend Equivalents.

8.  Other Stock-Based and Cash-Based Awards 

(a) General. The Board may grant other Awards of shares of Common Stock, and other Awards that are valued in whole or in part by reference to, or are 
otherwise based on, shares of Common Stock or other property (“Other Stock-Based Awards”). Such Other Stock-Based Awards shall also be available as 
a form of payment in the settlement of other Awards granted under the Plan or as payment in lieu of compensation to which a Participant is otherwise 
entitled. Other Stock-Based Awards may be paid in shares of Common Stock or cash, as the Board shall determine. The Company may also grant Awards 
denominated in cash rather than shares of Common Stock (“Cash-Based Awards”).

 
 
(b) Terms and Conditions. Subject to the provisions of the Plan, the Board shall determine the terms and conditions of each Other Stock-Based Award or 
Cash-Based Awards, including any purchase price applicable thereto.

(c) Dividend Equivalents. The Award agreement for an Other Stock-Based Award may provide Participants with the right to receive Dividend Equivalents. 
Dividend Equivalents may be paid currently or credited to an account for the Participant and may be settled in cash and/or shares of Common Stock, in 
each case to the extent provided in the Award Agreement, and shall be subject to the same restrictions on transfer and forfeitability as the Other Stock-
Based Award with respect to which such Dividend Equivalents are paid. No interest will be paid on Dividend Equivalents.

9.  Performance Awards.

(a) Grants. Awards under the Plan may be made subject to the achievement of performance goals pursuant to this Section 9 (“Performance Awards”).

(b) Performance Measures. The Board may specify that the degree of granting, vesting and/or payout shall be subject to the achievement of one or more 
objective performance measures established by the Board, which may be based on the relative or absolute attainment of specified levels of one or any 
combination of the following, which may be determined in accordance with generally accepted accounting principles (“GAAP”) or on a non-GAAP basis, 
as determined by the Board: (i) the entry into an arrangement or agreement with a third party for the development, commercialization, marketing or 
distribution of products, services or technologies, or for conducting a research program to discover and develop a product, service or technology, and/or the 
achievement of milestones under such arrangement or agreement, including events that trigger an obligation or payment right; (ii) achievement of domestic 
and international regulatory milestones, including the submission of filings required to advance products, services and technologies in clinical development 
and the achievement of approvals by regulatory authorities relating to the commercialization of products, services and technologies; (iii) the achievement of 
discovery, preclinical and clinical stage scientific objectives, discoveries or inventions for products, services and technologies under research and 
development; (iv) the entry into or completion of a phase of clinical development for any product, service or technology, such as the entry into or 
completion of phase 1, 2 and/or 3 clinical trials; (v) the consummation of debt or equity financing transactions, or acquisitions of business, technologies 
and assets; (vi) new product or service releases; (vii) the achievement of qualitative or quantitative performance measures set forth in operating plans 
approved by the Board from time to time; (viii) specified levels of product sales, net income, earnings before or after discontinued operations, interest, 
taxes, depreciation and/or amortization, operating profit before or after discontinued operations and/or taxes, sales, sales growth, earnings growth, cash 
flow or cash position, gross margins, stock price, market share, return on sales, assets, equity or investment; (ix) improvement of financial ratings; (x) 
achievement of balance sheet or income statement objectives; (xi) total stockholder return; (xii) other comparable measures of financial and operational 
performance; and/ or (xiii) any other measure selected by the Board. Such goals may reflect absolute entity or business unit performance or a relative 
comparison to the performance of a peer group of entities or other external measure of the selected performance criteria and may be absolute in their terms 
or measured against or in relationship to other companies comparably, similarly or otherwise situated. The Board may specify that such performance 
measures shall be adjusted to exclude any one or more of (i) non-recurring or unusual gains or losses, (ii) gains or losses on the dispositions of discontinued 
operations, (iii) the cumulative effects of changes in accounting principles, (iv) the writedown of any asset, (v) fluctuation in foreign currency exchange 
rates, (vi) charges for restructuring and rationalization programs and (vii) any other item or items determined by the Board. Such performance measures: 
(x) may vary by Participant and may be different for different Awards; and (y) may be particular to a Participant or the department, branch, line of business, 
subsidiary or other unit in which the Participant works and may cover such period as may be specified by the Board.

(c) Adjustments. Notwithstanding any provision of the Plan, with respect to any Performance Award, the Board may waive the achievement of the 
applicable performance measures or otherwise amend Performance Awards in a manner permitted under the Plan.

10.  Adjustments for Changes in Common Stock and Certain Other Events 

(a) Changes in Capitalization. In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of 
shares, spin-off or other similar change in capitalization or event, or any 

 
 
dividend or distribution to holders of Common Stock other than an ordinary cash dividend, (i) the number and class of securities available under the Plan, 
(ii) the share counting rules set forth in Section 4(a), (iii) the number and class of securities and exercise price per share of each outstanding Option, (iv) the 
share and per-share provisions and the measurement price of each outstanding SAR, (v) the number of shares subject to and the repurchase price per share 
subject to each outstanding award of Restricted Stock and (vi) the share and per-share-related provisions and the purchase price, if any, of each outstanding 
RSU and each Other Stock-Based Award, shall be equitably adjusted by the Company (or substituted Awards may be made, if applicable) in the manner 
determined by the Board. Without limiting the generality of the foregoing, in the event the Company effects a split of the Common Stock by means of a 
stock dividend and the exercise price of and the number of shares subject to an outstanding Option are adjusted as of the date of the distribution of the 
dividend (rather than as of the record date for such dividend), then an optionee who exercises an Option between the record date and the distribution date 
for such stock dividend shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon 
such Option exercise, notwithstanding the fact that such shares were not outstanding as of the close of business on the record date for such stock dividend.

(b) Reorganization Events.

(1) Definition. A “Reorganization Event” shall mean: (a) any merger or consolidation of the Company with or into another entity as a result of which all of 
the Common Stock of the Company is converted into or exchanged for the right to receive cash, securities or other property or is cancelled, (b) any transfer 
or disposition of all of the Common Stock of the Company for cash, securities or other property pursuant to a share exchange or other transaction or (c) any 
liquidation or dissolution of the Company.

(2) Consequences of a Reorganization Event on Awards Other than Restricted Stock.

(A) In connection with a Reorganization Event, the Board may take any one or more of the following actions as to all or any (or any portion of) outstanding 
Awards other than Restricted Stock on such terms as the Board determines (except to the extent specifically provided otherwise in an applicable Award 
agreement or another agreement between the Company and the Participant): (i) provide that such Awards shall be assumed, or substantially equivalent 
Awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to a Participant, provide that all of 
the Participant’s unvested Awards will be forfeited immediately prior to the consummation of such Reorganization Event and/ or that all of the Participant’s 
unexercised Awards will terminate immediately prior to the consummation of such Reorganization Event unless exercised by the Participant (to the extent 
then exercisable) within a specified period following the date of such notice, (iii) provide that outstanding Awards shall become exercisable, realizable or 
deliverable, or restrictions applicable to an Award shall lapse, in whole or in part prior to or upon such Reorganization Event, (iv) in the event of a 
Reorganization Event under the terms of which holders of Common Stock will receive upon consummation thereof a cash payment for each share 
surrendered in the Reorganization Event (the “Acquisition Price”), make or provide for a cash payment to Participants with respect to each Award held by 
a Participant equal to (A) the number of shares of Common Stock subject to the vested portion of the Award (after giving effect to any acceleration of 
vesting that occurs upon or immediately prior to such Reorganization Event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) the 
exercise, measurement or purchase price of such Award and any applicable tax withholdings, in exchange for the termination of such Award, (v) provide 
that, in connection with a liquidation or dissolution of the Company, Awards shall convert into the right to receive liquidation proceeds (if applicable, net of 
the exercise, measurement or purchase price thereof and any applicable tax withholdings) and (vi) any combination of the foregoing. In taking any of the 
actions permitted under this Section 10(b)(2)(A), the Board shall not be obligated by the Plan to treat all Awards, all Awards held by a Participant, or all 
Awards of the same type, identically.

(B) Notwithstanding the terms of Section 10(b)(2)(A)(i), in the case of outstanding RSUs that are subject to Section 409A: (i) if the applicable RSU 
agreement provides that the RSUs shall be settled upon a “change in control event” within the meaning of Treasury Regulation Section 1.409A-3(i)(5)(i), 
and the Reorganization Event constitutes such a “change in control event”, then no assumption or substitution shall be permitted pursuant to Section 10(b)
(2)(A)(i) and the RSUs shall instead be settled in accordance with the terms of the applicable RSU agreement; and (ii) the Board may only undertake the 
actions set forth in clauses (iii), (iv) or (v) of Section 10(b)(2)(A) if the Reorganization Event constitutes a “change in control event” as defined under 
Treasury Regulation Section 1.409A-3(i)(5)(i) and such action is permitted or required by Section 409A; if the Reorganization Event is not a “change in 

 
 
control event” as so defined or such action is not permitted or required by Section 409A, and the acquiring or succeeding corporation does not assume or 
substitute the RSUs pursuant to clause (i) of Section 10(b)(2)(A), then the unvested RSUs shall terminate immediately prior to the consummation of the 
Reorganization Event without any payment in exchange therefor.

(C) For purposes of Section 10(b)(2)(A)(i), an Award (other than Restricted Stock) shall be considered assumed if, following consummation of the 
Reorganization Event, such Award confers the right to purchase or receive pursuant to the terms of such Award, for each share of Common Stock subject to 
the Award immediately prior to the consummation of the Reorganization Event, the consideration (whether cash, securities or other property) received as a 
result of the Reorganization Event by holders of Common Stock for each share of Common Stock held immediately prior to the consummation of the 
Reorganization Event (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the 
outstanding shares of Common Stock); provided, however, that if the consideration received as a result of the Reorganization Event is not solely common 
stock of the acquiring or succeeding corporation (or an affiliate thereof), the Company may, with the consent of the acquiring or succeeding corporation, 
provide for the consideration to be received upon the exercise or settlement of the Award to consist solely of such number of shares of common stock of the 
acquiring or succeeding corporation (or an affiliate thereof) that the Board determined to be equivalent in value (as of the date of such determination or 
another date specified by the Board) to the per share consideration received by holders of outstanding shares of Common Stock as a result of the 
Reorganization Event.

(3) Consequences of a Reorganization Event on Restricted Stock. Upon the occurrence of a Reorganization Event other than a liquidation or dissolution of 
the Company, the repurchase and other rights of the Company with respect to outstanding Restricted Stock shall inure to the benefit of the Company’s 
successor and shall, unless the Board determines otherwise, apply to the cash, securities or other property which the Common Stock was converted into or 
exchanged for pursuant to such Reorganization Event in the same manner and to the same extent as they applied to such Restricted Stock; provided, 
however, that the Board may either provide for termination or deemed satisfaction of such repurchase or other rights under the instrument evidencing any 
Restricted Stock or any other agreement between a Participant and the Company, either initially or by amendment, or provide for forfeiture of such 
Restricted Stock if issued at no cost. Upon the occurrence of a Reorganization Event involving the liquidation or dissolution of the Company, except to the 
extent specifically provided to the contrary in the instrument evidencing any Restricted Stock or any other agreement between a Participant and the 
Company, all restrictions and conditions on all Restricted Stock then outstanding shall automatically be deemed terminated or satisfied.

11.  General Provisions Applicable to Awards 

(a) Transferability of Awards. Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by a Participant, either voluntarily or by 
operation of law, except by will or the laws of descent and distribution or, other than in the case of an Incentive Stock Option, pursuant to a qualified 
domestic relations order, and, during the life of the Participant, shall be exercisable only by the Participant; provided, however, that, except with respect to 
Awards subject to Section 409A, the Board may permit or provide in an Award for the gratuitous transfer of the Award by the Participant to or for the 
benefit of any immediate family member, family trust or other entity established for the benefit of the Participant and/or an immediate family member 
thereof if the Company would be eligible to use a Form S-8 under the Securities Act for the registration of the sale of the Common Stock subject to such 
Award to such proposed transferee; provided further, that the Company shall not be required to recognize any such permitted transfer until such time as 
such permitted transferee shall, as a condition to such transfer, deliver to the Company a written instrument in form and substance satisfactory to the 
Company confirming that such transferee shall be bound by all of the terms and conditions of the Award. References to a Participant, to the extent relevant 
in the context, shall include references to authorized transferees. For the avoidance of doubt, nothing contained in this Section 11(a) shall be deemed to 
restrict a transfer to the Company.

(b) Documentation. Each Award shall be evidenced in such form (written, electronic or otherwise) as the Board shall determine. Each Award may contain 
terms and conditions in addition to those set forth in the Plan.

(c) Termination of Status. The Board shall determine the effect on an Award of the disability, death, termination or other cessation of employment, 
authorized leave of absence or other change in the employment or other status of a Participant and the extent to which, and the period during which, the 
Participant, or the Participant’s legal 

 
 
representative, conservator, guardian or Designated Beneficiary, may exercise rights, or receive any benefits, under an Award.

(d) Withholding. The Participant must satisfy all applicable federal, state, and local or other income and employment tax withholding obligations before the 
Company will deliver stock certificates or otherwise recognize ownership of Common Stock under an Award. The Company may elect to satisfy the 
withholding obligations through additional withholding on salary or wages. If the Company elects not to or cannot withhold from other compensation, the 
Participant must pay the Company the full amount, if any, required for withholding or have a broker tender to the Company cash equal to the withholding 
obligations. Payment of withholding obligations is due before the Company will issue any shares on exercise, vesting or release from forfeiture of an 
Award or at the same time as payment of the exercise or purchase price, unless the Company determines otherwise. If provided for in an Award or approved 
by the Board, a Participant may satisfy the tax obligations in whole or in part by delivery (either by actual delivery or attestation) of shares of Common 
Stock, including shares retained from the Award creating the tax obligation, valued at their fair market value (valued in the manner determined by (or in a 
manner approved by) the Company); provided, however, except as otherwise provided by the Board, that the total tax withholding where stock is being 
used to satisfy such tax obligations cannot exceed the Company’s minimum statutory withholding obligations (based on minimum statutory withholding 
rates for federal and state tax purposes, including payroll taxes, that are applicable to such supplemental taxable income), except that, to the extent that the 
Company is able to retain shares of Common Stock having a fair market value (determined by, or in a manner approved by, the Company) that exceeds the 
statutory minimum applicable withholding tax without financial accounting implications or the Company is withholding in a jurisdiction that does not have 
a statutory minimum withholding tax, the Company may retain such number of shares of Common Stock (up to the number of shares having a fair market 
value equal to the maximum individual statutory rate of tax (determined by, or in a manner approved by, the Company)) as the Company shall determine in 
its sole discretion to satisfy the tax liability associated with any Award. Shares used to satisfy tax withholding requirements cannot be subject to any 
repurchase, forfeiture, unfulfilled vesting or other similar requirements.

(e) Amendment of Award. Except as otherwise provided in Sections 5(g) and 6(e) with respect to repricings and Section 12(d) with respect to actions 
requiring stockholder approval, the Board may amend, modify or terminate any outstanding Award, including but not limited to, substituting therefor 
another Award of the same or a different type, changing the date of exercise or realization, and converting an Incentive Stock Option to a Nonstatutory 
Stock Option. The Participant’s consent to such action shall be required unless (i) the Board determines that the action, taking into account any related 
action, does not materially and adversely affect the Participant’s rights under the Plan or (ii) the change is permitted under Section 10.

(f) Conditions on Delivery of Stock. The Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove 
restrictions from shares previously issued or delivered under the Plan until (i) all conditions of the Award have been met or removed to the satisfaction of 
the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such shares have been 
satisfied, including any applicable securities laws and regulations and any applicable stock exchange or stock market rules and regulations, and (iii) the 
Participant has executed and delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the 
requirements of any applicable laws, rules or regulations.

(g) Acceleration. The Board may at any time provide that any Award shall become immediately exercisable in whole or in part, free from some or all 
restrictions or conditions or otherwise realizable in whole or in part, as the case may be.

12. Miscellaneous 

(a) No Right To Employment or Other Status. No person shall have any claim or right to be granted an Award by virtue of the adoption of the Plan, and the 
grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The 
Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under 
the Plan, except as expressly provided in the applicable Award.

 
 
(b) No Rights As Stockholder; Clawback. Subject to the provisions of the applicable Award, no Participant or Designated Beneficiary shall have any rights 
as a stockholder with respect to any shares of Common Stock to be issued with respect to an Award until becoming the record holder of such shares. In 
accepting an Award under the Plan, the Participant agrees to be bound by any clawback policy that the Company has in effect or may adopt in the future.

(c) Effective Date and Term of Plan. The Plan shall become effective on the date the Plan is approved by the Company’s stockholders (the “Effective 
Date”). No Awards shall be granted under the Plan after the expiration of 10 years from the Effective Date, but Awards previously granted may extend 
beyond that date.

(d) Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time provided that (i) no amendment that 
would require stockholder approval under the rules of the national securities exchange on which the Company then maintains its primary listing may be 
made effective unless and until the Company’s stockholders approve such amendment; and (ii) if the national securities exchange on which the Company 
then maintains its primary listing does not have rules regarding when stockholder approval of amendments to equity compensation plans is required (or if 
the Company’s Common Stock is not then listed on any national securities exchange), then no amendment to the Plan (A) materially increasing the number 
of shares authorized under the Plan (other than pursuant to Section 4(c) or 10), (B) expanding the types of Awards that may be granted under the Plan, or 
(C) materially expanding the class of participants eligible to participate in the Plan shall be effective unless and until the Company’s stockholders approve 
such amendment. In addition, if at any time the approval of the Company’s stockholders is required as to any other modification or amendment under 
Section 422 of the Code or any successor provision with respect to Incentive Stock Options, the Board may not effect such modification or amendment 
without such approval. Unless otherwise specified in the amendment, any amendment to the Plan adopted in accordance with this Section 12(d) shall apply 
to, and be binding on the holders of, all Awards outstanding under the Plan at the time the amendment is adopted, provided the Board determines that such 
amendment, taking into account any related action, does not materially and adversely affect the rights of Participants under the Plan. No Award shall be 
made that is conditioned upon stockholder approval of any amendment to the Plan unless the Award provides that (i) it will terminate or be forfeited if 
stockholder approval of such amendment is not obtained within no more than 12 months from the date of grant and (2) it may not be exercised or settled (or 
otherwise result in the issuance of Common Stock) prior to such stockholder approval.

(e) Authorization of Sub-Plans (including for Grants to non-U.S. Employees). The Board may from time to time establish one or more sub-plans under the 
Plan for purposes of satisfying applicable securities, tax or other laws of various jurisdictions. The Board shall establish such sub-plans by adopting 
supplements to the Plan containing (i) such limitations on the Board’s discretion under the Plan as the Board deems necessary or desirable or (ii) such 
additional terms and conditions not otherwise inconsistent with the Plan as the Board shall deem necessary or desirable. All supplements adopted by the 
Board shall be deemed to be part of the Plan, but each supplement shall apply only to Participants within the affected jurisdiction and the Company shall 
not be required to provide copies of any supplement to Participants in any jurisdiction which is not the subject of such supplement.

(f) Compliance with Section 409A of the Code. If and to the extent (i) any portion of any payment, compensation or other benefit provided to a Participant 
pursuant to the Plan in connection with his or her employment termination constitutes “nonqualified deferred compensation” within the meaning of Section 
409A and (ii) the Participant is a specified employee as defined in Section 409A(a)(2)(B)(i) of the Code, in each case as determined by the Company in 
accordance with its procedures, by which determinations the Participant (through accepting the Award) agrees that he or she is bound, such portion of the 
payment, compensation or other benefit shall not be paid before the day that is six months plus one day after the date of “separation from service” (as 
determined under Section 409A) (the “New Payment Date”), except as Section 409A may then permit. The aggregate of any payments that otherwise 
would have been paid to the Participant during the period between the date of separation from service and the New Payment Date shall be paid to the 
Participant in a lump sum on such New Payment Date, and any remaining payments will be paid on their original schedule.

The Company makes no representations or warranty and shall have no liability to the Participant or any other person if any provisions of or payments, 
compensation or other benefits under the Plan are determined to constitute nonqualified deferred compensation subject to Section 409A but do not to 
satisfy the conditions of that section.

 
 
(g) Limitations on Liability. Notwithstanding any other provisions of the Plan, no individual acting as a director, officer, employee or agent of the Company 
will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection 
with the Plan, nor will such individual be personally liable with respect to the Plan because of any contract or other instrument he or she executes in his or 
her capacity as a director, officer, employee or agent of the Company. The Company will indemnify and hold harmless each director, officer, employee or 
agent of the Company to whom any duty or power relating to the administration or interpretation of the Plan has been or will be delegated, against any cost 
or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Board’s approval) arising out of any act or 
omission to act concerning the Plan unless arising out of such person’s own fraud or bad faith.

(h) Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the 
State of Delaware, excluding choice-of-law principles of the law of such state that would require the application of the laws of a jurisdiction other than the 
State of Delaware.

Committee, but not inconsistent with the Plan. The Committee shall determine whether an Award shall include one type 
of Incentive or two or more Incentives granted in combination or two or more Incentives granted in tandem (that is, a 
joint grant where exercise of one Incentive results in cancellation of all or a portion of the other Incentive). Although the

formula by which such price or prices may be determined) to be paid for the purchase of the Common Stock subject to 
such Awards, and (z) not authorize an officer to designate himself as a recipient of any Award.

3.3 Authority of the Committee. The Committee, in its discretion, shall (i) interpret the Plan, (ii) prescribe,

determination, or other action made or taken by the Committee shall be final, binding, and conclusive on all interested parties. 
The Committee’s discretion set forth herein shall not be limited by any provision of the Plan, including any provision which by 
its tennis is applicable notwithstanding any other provision of the Plan to the contrary.

The  Committee  may  delegate  to  officers  of  the  Company,  pursuant  to  a  written  delegation,  the  authority  to  perform 
specified  functions  under  the  Plan.  Any  actions  taken  by  any  officers  of  the  Company  pursuant  to  such  written  delegation  of

Company’s securities are listed or quoted, or any other applicable law, rule or restriction (collectively, “applicable law”), to the 
extent  that  any  such  restrictions  are  no  longer  required  by  applicable  law,  the  Committee  shall  have  the  sole  discretion  and 
authority to grant Awards that are not subject to such mandated restrictions and/or to waive any such mandated restrictions with 
respect to outstanding Awards.

shall  determine.  Except  as  required  by  this  Plan,  Awards  granted  at  different  times  need  not  contain  similar  provisions.  The 
Committee’s  determinations  under  the  Plan  (including  without  limitation  determinations  of  which  Employees,  Consultants  or 
Outside Directors, if any, are to receive Awards, the form, amount and timing of such Awards, the terms and provisions of 

 
 
 
such Awards and the agreements evidencing same) need not be uniform and may be made by it selectively among Participants 
who receive, or are eligible to receive, Awards under the Plan.

ARTICLE 5
SHARES SUBJECT TO PLAN

5.1 Number Available for Awards. Subject to adjustment as provided in Articles 11 and 12, the maximum 
number of shares of Common Stock that may be delivered pursuant to Awards granted under the Plan is 14,188,922 shares, 100% 
of which may be delivered pursuant to Incentive Stock Options. Shares to be issued may be made available from authorized but 
unissued Common Stock, Common Stock held by the Company in its treasury, or Common Stock purchased by the Company on 
the open market or otherwise. During the term of this Plan, the Company will at all times reserve and keep available the number 
of shares of Common Stock that shall be sufficient to satisfy the requirements of this Plan.

5.2 Reuse of Shares. To the extent that any Award under this Plan may be forfeited, expires or canceled, in 
whole or in part, then the number of shares of Common Stock covered by the Award or Stock Option so forfeited, expired or 
canceled may again be awarded pursuant to the provisions of this Plan. In the event that previously acquired shares of Common 
Stock are delivered to the Company in full or partial payment of the exercise price for the exercise of a Stock Option granted 
under this Plan, the number of shares of Common Stock available for future Awards under this Plan shall be reduced only by the 
net number of shares of Common Stock issued upon the exercise of the Stock Option. Awards that may be satisfied either by the 
issuance of shares of Common Stock or by cash or other consideration shall be counted against the maximum number of shares 
of Common Stock that may be issued under this Plan only during the period that the Award is outstanding or to the extent the 
Award  is  ultimately  satisfied  by  the  issuance  of  shares  of  Common  Stock.  Notwithstanding  any  provisions  of  the  Plan  to  the 
contrary, only shares forfeited back to the Company, shares canceled on account of termination, expiration or lapse of an Award, 
shares surrendered in payment of the exercise price of an option or shares withheld for payment of applicable employment taxes 
and/or  withholding  obligations  resulting  from  the  exercise  of  an  option  shall  again  be  available  for  grant  of  Incentive  Stock 
Options under the Plan, but shall not increase the maximum number of shares described in Section 5.1 above as the maximum 
number of shares of Common Stock that may be delivered pursuant to Incentive Stock Options.

ARTICLE 6
GRANT OF AWARDS

6.1

In General.

(a)

The  grant  of  an  Award  shall  be  authorized  by  the  Committee  and  shall  be  evidenced  by  an  Award 
Agreement setting forth the Incentive or Incentives being granted, the total number of shares of Common Stock subject 
to the Incentive(s), the Grant Price (if applicable), the Award Period, the Date of Grant, and such other terms, provisions, 
limitations, and performance objectives, as are approved by the Committee, but (i) not inconsistent with the Plan and (ii) 
to the extent an Award issued under the Plan is subject to Section 409A of the Code, in compliance with the applicable 
requirements of Section 409A of the Code and the regulations or other guidance issued thereunder. The Company 

 
 
 
 
shall  execute  an  Award  Agreement  with  a  Participant  after  the  Committee  approves  the  issuance  of  an  Award.  Any 
Award granted pursuant to this Plan must be granted within ten (10) years of the date of adoption of this Plan. The Plan 
must be submitted to the Company’s shareholders for approval; however, the Committee may grant Awards under the 
Plan prior to the time of shareholder approval. Any such Award granted prior to such shareholder approval will be made 
subject  to  such  shareholder  approval.  The  grant  of  an  Award  to  a  Participant  shall  not  be  deemed  either  to  entitle  the 
Participant to, or to disqualify the Participant from, receipt of any other Award under the Plan.

(b)

If  the  Committee  establishes  a  purchase  price  for  an  Award,  the  Participant  must  accept  such  Award 
within  a  period  of  thirty  (30)  days  (or  such  shorter  period  as  the  Committee  may  specify)  after  the  Date  of  Grant  by 
executing the applicable Award Agreement and paying such purchase price.

(c)

Except  as  otherwise  provided  herein,  a  Participant  shall  have  no  rights  as  a  holder  of  any  unissued 
securities covered by an Award until the date the Participant becomes the holder of record if such securities. Except as 
provided in Section 11 hereof, no adjustment or other provision shall be made for dividends or other rights with respect 
to such securities, except to the extent that the Award Agreement provides for dividend payments or dividend equivalent 
rights.

(d) An Award Agreement may not include provisions that “reload” the Award upon exercise.

(e)

The  Committee  may  specify  in  an  Award  Agreement  at  the  time  of  Award  that  the  Participant’s  rights, 
payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon 
the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of 
an  Award.  Such  events  may  include,  but  shall  not  be  limited  to,  violation  of  material  Company  policies,  breach  of 
noncompetition, confidentiality or other restrictive covenants that may apply to the Participant, or other conduct by the 
Participant that is detrimental to the business or reputation of the Company.

6.2 Grant  Price.  The  Grant  Price  for  any  share  of  Common  Stock  that  may  be  purchased  under  a 
Nonqualified Stock Option may be equal to or greater than the Fair Market Value of the share on the Date of Grant. The Grant 
Price for any share of Common Stock that may be purchased under an Incentive Stock Option must be at least equal to the Fair 
Market Value of the share on the Date of Grant; if an Incentive Stock Option is granted to an Employee who owns or is deemed 
to own (by reason of the attribution rules of Section 424(d) of the Code) more than ten percent (10%) of the combined voting 
power of all classes of stock of the Company (or any Parent or Subsidiary), the Grant Price must be at least 110% of the Fair 
Market Value of the Common Stock on the Date of Grant.

6.3 Maximum ISO Grants.  The  Committee  may  not  grant  Incentive  Stock  Options  under  the  Plan  to  any 
Employee  that  would  permit  the  aggregate  Fair  Market  Value  (determined  on  the  Date  of  Grant)  of  the  Common  Stock  with 
respect to which Incentive Stock Options (under this and any other plan of the Company and its Subsidiaries) are exercisable for 

 
 
 
the first time by such Employee during any calendar year to exceed $100,000. To the extent any Stock Option granted under this 
Plan that is designated as an Incentive Stock Option exceeds this limit or otherwise fails to qualify as an Incentive Stock Option, 
such  Stock  Option  (or  any  such  portion  thereof)  shall  be  a  Nonqualified  Stock  Option.  In  such  case,  the  Committee  shall 
designate which stock will be treated as Incentive Stock Option stock by causing the issuance of a separate stock certificate and 
identifying such stock as Incentive Stock Option stock on the Company’s stock transfer records.

6.4 Restricted Stock. If Restricted Stock is granted to or received by a Participant under an Award (including 
a  Stock  Option),  the  Committee  shall  set  forth  in  the  related  Award  Agreement:  (i)  the  number  of  shares  of  Common  Stock 
awarded, (ii) the price, if any, to be paid by the Participant for such Restricted Stock and the method of payment of the price, (iii) 
the  time  or  times  within  which  such  Award  may  be  subject  to  forfeiture,  (iv)  specified  Performance  Goals  of  the  Company,  a 
Parent  or  Subsidiary,  any  division  thereof  or  any  group  of  Employees  of  the  Company,  or  other  criteria,  that  the  Committee 
determines  must  be  met  in  order  to  remove  any  restrictions  (including  vesting)  on  such  Award,  and  (v)  all  other  terms, 
limitations,  restrictions,  and  conditions  of  the  Restricted  Stock,  which  shall  be  consistent  with  this  Plan  and  to  the  extent  a 
Restricted Stock granted under the Plan is subject to Section 409A of the Code, in compliance with the applicable requirements 
of Section 409A of the Code and the regulations or other guidance issued thereunder. The provisions of Restricted Stock need not 
be the same with respect to each Participant.

(a)

Legend on Shares. Each Participant who is awarded or receives Restricted Stock will be issued a stock 
certificate or certificates in respect of such shares of Common Stock. Such certificate(s) shall be registered in the name 
of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to 
such Restricted Stock, substantially as provided in Section 15.9 of the Plan.

(b) Restrictions and Conditions. Shares of Restricted Stock shall be subject to the following restrictions and 

conditions:

(i)Subject  to  the  other  provisions  of  this  Plan  and  the  terms  of  the  particular  Award  Agreements, 
during such period as may be determined by the Committee commencing on the Date of Grant or the date of 
exercise of an Award (the “Restriction Period”), the Participant shall not be permitted to sell, transfer, pledge 
or assign shares of Restricted Stock. Except for these limitations, the Committee may in its sole discretion, 
remove any or all of the restrictions on such Restricted Stock whenever it may determine that, by reason of 
changes in applicable laws or other changes in circumstances arising after the date of the Award, such action 
is appropriate.

(ii)Except  as  provided  in  sub-paragraph  (i)  above  or  in  the  applicable  Award  Agreement,  the 
Participant  will  have,  with  respect  to  his  or  her  Restricted  Stock,  all  of  the  rights  of  a  shareholder  of  the 
Company, including the right to vote the shares, and the right to receive any dividends thereon. Certificates 
for shares of Common Stock free of restriction under this Plan shall be delivered to the Participant promptly 
after,  and  only  after,  the  Restriction  Period  shall  expire  without  forfeiture  in  respect  of  such  shares  of 
Common Stock or after any other 

 
 
restrictions  imposed  in  such  shares  of  Common  Stock  by  the  applicable  Award  Agreement  or  other 
agreement have expired. Certificates for the shares of Common Stock forfeited under the provisions of the 
Plan  and  the  applicable  Award  Agreement  shall  be  promptly  returned  to  the  Company  by  the  forfeiting 
Participant. Each Award Agreement shall require that each Participant, in connection with the issuance of a 
certificate  for  Restricted  Stock,  shall  endorse  such  certificate  in  blank  or  execute  a  stock  power  in  form 
satisfactory to the Company in blank and deliver such certificate and executed stock power to the Company.

(iii)The Restriction Period of Restricted Stock shall commence on the Date of Grant or the date of 
exercise  of  an  Award,  as  specified  in  the  Award  Agreement,  and,  subject  to  Article 12  of  the  Plan,  unless 
otherwise  established  by  the  Committee  in  the  Award  Agreement  setting  forth  the  terms  of  the  Restricted 
Stock, shall expire upon satisfaction of the conditions set forth in the Award Agreement; such conditions may 
provide  for  vesting  based  on  such  Performance  Goals,  as  may  be  determined  by  the  Committee  in  its  sole 
discretion.

(iv)Except as otherwise provided in the particular Award Agreement, upon Termination of Service 
for any reason during the Restriction Period, the nonvested shares of Restricted Stock shall be forfeited by 
the  Participant.  In  the  event  a  Participant  has  paid  any  consideration  to  the  Company  for  such  forfeited 
Restricted Stock, the Committee shall specify in the Award Agreement that either (i) the Company shall be 
obligated  to,  or  (ii)  the  Company  may,  in  its  sole  discretion,  elect  to,  pay  to  the  Participant,  as  soon  as 
practicable after the event causing forfeiture, in cash, an amount equal to the lesser of the total consideration 
paid by the Participant for such forfeited shares or the Fair Market Value of such forfeited shares as of the 
date of Termination of Service, as the Committee, in its sole discretion shall select. Upon any forfeiture, all 
rights of a Participant with respect to the forfeited shares of the Restricted Stock shall cease and terminate, 
without any further obligation on the part of the Company.

(c)

Section  83(b)  Election.  If  a  Participant  makes  an  election  pursuant  to  Section  83(b)  of  the  Code  with 
respect to an Award of Restricted Stock, the Participant shall file, within 30 days following the Date of Grant, a copy of 
such election with the Company and with the Internal Revenue Service, in accordance with the regulations under Section 
83(b)  of  the  Code.  The  Committee  may  provide  in  an  Award  Agreement  that  the  Award  of  Restricted  Stock  is 
conditioned upon the Participant’s making or refraining from making an election with respect to the Award under Section
83(b) of the Code.

6.5

Performance Goals. Awards of Restricted Stock under the Plan may be made subject to the attainment of 
Performance Goals relating to one or more business criteria that, when applicable, shall be within the meaning of Section 162(m) 
of the Code and consist of one or more or any combination of the following criteria: cash flow; cost; revenues; sales; ratio of debt 
to debt plus equity; net borrowing, credit quality or debt ratings; profit before tax; economic profit; earnings before interest and 
taxes; earnings before interest, taxes, depreciation and amortization; gross margin; earnings per share (whether on a pre-tax, after-
tax, operational or other basis); 

 
 
operating earnings; capital expenditures; expenses or expense levels; economic value added; ratio of operating earnings to capital 
spending  or  any  other  operating  ratios;  free  cash  flow;  net  profit;  net  sales;  net  asset  value  per  share;  the  accomplishment  of 
mergers,  acquisitions,  dispositions,  public  offerings  or  similar  extraordinary  business  transactions;  sales  growth;  price  of  the 
Company’s  Common  Stock;  return  on  assets,  equity  or  shareholders’  equity;  market  share;  inventory  levels,  inventory  turn  or 
shrinkage;  or  total  return  to  shareholders  (“Performance  Criteria”).  Any  Performance  Criteria  may  be  used  to  measure  the 
performance of the Company as a whole or any business unit of the Company and may be measured relative to a peer group or 
index. Any Performance Criteria may include or exclude (i) extraordinary, unusual and/or non- recurring items of gain or loss, (ii) 
gains  or  losses  on  the  disposition  of  a  business,  (iii)  changes  in  tax  or  accounting  regulations  or  laws,  or  (iv)  the  effect  of  a 
merger or acquisition, as identified in the Company’s quarterly and annual earnings releases. In all other respects, Performance 
Criteria  shall  be  calculated  in  accordance  with  the  Company’s  financial  statements,  under  generally  accepted  accounting 
principles, or under a methodology established by the Committee prior to the issuance of an Award that is consistently applied 
and identified in the audited financial statements, including footnotes, or the Management Discussion and Analysis section of the 
Company’s annual report. However, to the extent Section 162(m) of the Code is applicable, the Committee may not in any event 
increase the amount of compensation payable to an individual upon the attainment of a Performance Goal.

6.6

Stock Appreciation Rights. An Award may be in the form of a SAR. The Grant Price of a SAR shall not 
be less than the Fair Market Value of the Common Stock subject to such SAR on the Date of Grant. The holder of a tandem SAR 
may elect to exercise either the Stock Option or the SAR, but not both. Subject to the foregoing provisions, the terms, conditions 
and limitations applicable to any SARs awarded to Employees pursuant to this Plan, including the Grant Price, the term of any 
SARs and the date or dates upon which they become exercisable, shall be determined by the Committee.

6.7 Effect of Award on Shareholders Agreement. Each Participant shall become a party to the Shareholders 
Agreement  as  a  condition  to  the  grant  of  any  Award  of  Restricted  Stock  or  the  exercise  of  a  Stock  Option,  whereupon  such 
Participant shall be deemed to be a Shareholder (as defined in the Shareholders Agreement) for all purposes of the Shareholders 
Agreement.

ARTICLE 7
AWARD PERIOD; VESTING

7.1 Award Period.  Subject  to  the  other  provisions  of  this  Plan,  the  Committee  may,  in  its  sole  discretion, 
provide that an Incentive may not be exercised in whole or in part for any period or periods of time or beyond any date specified 
in the Award Agreement. Except as provided in the Award Agreement, an Incentive may be exercised in whole or in part at any 
time  during  its  term.  The  Award  Period  for  an  Incentive  shall  be  reduced  or  terminated  upon  Termination  of  Service.  No 
Incentive granted under the Plan may be exercised at any time after the end of its Award Period. No portion of any Incentive may 
be exercised after the expiration of ten (10) years following its Date of Grant. However, if an Employee owns or is deemed to 
own (by reason of the attribution rules of Section 424(d) of the Code) more than ten percent (10%) of the combined voting power 
of all classes of stock of the Company (or any Parent or Subsidiary) and an Incentive Stock Option is granted to such Employee, 
the term of such Incentive Stock 

 
 
 
Option (to the extent required by the Code at the time of grant) may be no more than five (5) years following the Date of Grant.

7.2 Vesting.  The  Committee,  in  its  sole  discretion,  may  determine  that  an  Incentive  will  be  immediately 
vested in whole or in part, or that all or any portion may not be vested until a date, or dates, subsequent to its Date of Grant, or 
until the occurrence of one or more specified events, including a Change in Control, subject in any case to the terms of the Plan. 
If  the  Committee  imposes  conditions  upon  vesting,  then,  subsequent  to  the  Date  of  Grant,  the  Committee  may,  in  its  sole 
discretion, accelerate the date on which all or any portion of the Incentive may be vested.

ARTICLE 8
EXERCISE OR CONVERSION OF INCENTIVE

limitations and restrictions set forth in the Award Agreement

8.1

In  General.  A.  vested  Incentive  may  be  exercised  or  converted,  during  its  Award  Period,  subject  to 

8.2

Securities  Law  and  Exchange  Restrictions.  In  no  event  may  an  Incentive  be  exercised  or  shares  of 
Common  Stock  issued  pursuant  to  an  Award  if  a  necessary  listing  or  quotation  of  the  shares  of  Common  Stock  on  a  stock 
exchange  or  inter-dealer  quotation  system  or  any  registration  under  state  or  federal  securities  laws  required  under  the 
circumstances has not been accomplished.

8.3 Exercise of Stock Option.

(a)

In General. If a Stock Option is exercisable prior to the time it is vested, the Common Stock obtained on 
the exercise of the Stock Option shall be Restricted Stock that is subject to the applicable provisions of the Plan and the 
Award  Agreement.  If  the  Committee  imposes  conditions  upon  exercise,  then  subsequent  to  the  Date  of  Grant,  the 
Committee  may,  in  its  sole  discretion,  accelerate  the  date  on  which  all  or  any  portion  of  the  Stock  Option  may  be 
exercised. No Stock Option may be exercised for a fractional share of Common Stock. The granting of a Stock Option 
will impose no obligation upon the Participant to exercise that Stock Option.

(b) Notice and Payment. Subject to such administrative regulations as the Committee may from time to time 
adopt, a Stock Option may be exercised by the delivery of written notice to the Committee setting forth the number of 
shares of Common Stock with respect to which the Stock Option is to be exercised and the date of exercise thereof (the 
“Exercise Date”), which shall be at least three (3) days after giving such notice unless an earlier time shall have been 
mutually  agreed  upon.  On  the  Exercise  Date,  the  Participant  shall  deliver  to  the  Company  consideration  with  a  value 
equal to the total Grant Price of the shares to be purchased, payable as provided in the Award Agreement, which may 
provide for payment in any one or more of the following ways: (a) cash or check, bank draft, or money order payable to 
the  order  of  the  Company,  (b)  Common  Stock  (including  Restricted  Stock)  owned  by  the  Participant  on  the  Exercise 
Date,  valued  at  its  Fair  Market  Value  on  the  Exercise  Date,  and  which  the  Participant  has  not  acquired  from  the 
Company within six (6) months prior to the Exercise Date, (c) by delivery (including by FAX) to the Company or its 
designated agent of an executed irrevocable option exercise form together 

 
 
 
with irrevocable instructions from the Participant to a broker or dealer, reasonably acceptable to the Company, to sell 
certain  of  the  shares  of  Common  Stock  purchased  upon  exercise  of  the  Stock  Option  or  to  pledge  such  shares  as 
collateral for a loan  and  promptly  deliver  to  the  Company  the  amount  of  sale or loan proceeds necessary to pay such 
purchase price, or (d) in any other form of valid consideration that is acceptable to the Committee in its sole discretion. 
In the event that shares of Restricted Stock are tendered as consideration for the exercise of a Stock Option, a number of 
shares  of  Common  Stock  issued  upon  the  exercise  of  the  Stock  Option  with  an  Grant  Price  equal  to  the  value  of 
Restricted Stock used as consideration therefor shall be subject to the same restrictions and provisions as the Restricted 
Stock so tendered.

(c)

Issuance  of  Certificate.  Except  as  otherwise  provided  in  Section  6.4  hereof  (with  respect  to  shares  of 
Restricted  Stock)  or  in  the  applicable  Award  Agreement,  upon  payment  of  all  amounts  due  from  the  Participant,  the 
Company  shall  cause  certificates  for  the  Common  Stock  then  being  purchased  to  be  delivered  as  directed  by  the 
Participant  (or  the  person  exercising  the  Participant’s  Stock  Option  in  the  event  of  his  death)  at  its  principal  business 
office  promptly  after  the  Exercise  Date;  provided  that  if  the  Participant  has  exercised  an  Incentive  Stock  Option,  the 
Company  may  at  its  option  retain  physical  possession  of  the  certificate  evidencing  the  shares  acquired  upon  exercise 
until the expiration of the holding periods described in Section 422(a)(1) of the Code. The obligation of the Company to 
deliver  shares  of  Common  Stock  shall,  however,  be  subject  to  the  condition  that,  if  at  any  time  the  Committee 
determines in its sole discretion that the listing, registration, or qualification of the Stock Option or the Common Stock 
upon  any  securities  exchange  or  inter-dealer  quotation  system  or  under  any  state  or  federal  law,  or  the  consent  or 
approval of any governmental regulatory body, is necessary as a condition of, or in connection with, the Stock Option or 
the issuance or purchase of shares of Common Stock thereunder, the Stock Option may not be exercised in whole or in 
part unless such listing, registration, qualification, consent, or approval shall have been effected or obtained free of any 
conditions not reasonably acceptable to the Committee.

(d)

Failure to Pay. Except as may otherwise be provided in an Award Agreement, if the Participant fails to 
pay  for  any  of  the  Common  Stock  specified  in  such  notice  or  fails  to  accept  delivery  thereof,  that  portion  of  the 
Participant’s Stock Option and right to purchase such Common Stock may be forfeited, at the option of the Committee.

8.4 Disqualifying  Disposition  of  Incentive  Stock  Option.  If  shares  of  Common  Stock  acquired  upon 
exercise of an Incentive Stock Option are disposed of by a Participant prior to the expiration of either two (2) years from the Date 
of Grant of such Stock Option or one (1) year from the transfer of shares of Common Stock to the Participant pursuant to the 
exercise  of  such  Stock  Option,  or  in  any  other  disqualifying  disposition  within  the  meaning  of  Section  422  of  the  Code,  such 
Participant  must  notify  the  Company  in  writing  of  the  date  and  terms  of  such  disposition.  A  disqualifying  disposition  by  a 
Participant shall not affect the status of any other Stock Option granted under the Plan as an Incentive Stock Option within the 
meaning of Section 422 of the Code.

 
 
ARTICLE 9
AMENDMENT OR DISCONTINUANCE

Subject to the limitations set forth in this Article 9, the Board may at any time and from time to time, without the consent 
of  the  Participants,  alter,  amend,  revise,  suspend,  or  discontinue  the  Plan  in  whole  or  in  part;  provided,  however,  that  no 
amendment for which shareholder approval is required either (i) by any securities exchange or inter-dealer quotation system on 
which the Common Stock is listed or traded or (ii) in order for the Plan and Incentives awarded under the Plan to continue to 
comply with Sections 162(m), 421, and 422 of the Code, including any successors to such Sections, may be effective unless such 
amendment  shall  be  approved  by  the  requisite  vote  of  the  shareholders  of  the  Company  entitled  to  vote  thereon.  Any  such 
amendment  shall,  to  the  extent  deemed  necessary  or  advisable  by  the  Committee,  be  applicable  to  any  outstanding  Incentives 
theretofore granted under the Plan, notwithstanding any contrary provisions contained in any Award Agreement. In the event of 
any such amendment to the Plan, the holder of any Incentive outstanding under the Plan shall, upon request of the Committee and 
as a condition to the exercisability thereof, execute a conforming amendment in the form prescribed by the Committee to any 
Award Agreement relating thereto. Notwithstanding anything contained in this Plan to the contrary, unless required by law, no 
action contemplated or permitted by this Article 9 shall adversely affect any rights of Participants or obligations of the Company 
to Participants with respect to any Incentive theretofore granted under the Plan without the consent of the affected Participant.

ARTICLE 10
TERM

The Plan shall be effective from the date that this Plan is approved by the Board. Unless sooner terminated by action of 
the Board, the Plan will terminate on October 23, 2023, but Incentives granted before that date will continue to be effective in 
accordance with their terms and conditions.

ARTICLE 11
CAPITAL ADJUSTMENTS

In  the  event  that  any  dividend  or  other  distribution  (whether  in  the  form  of  cash,  Common  Stock,  other  securities,  or 
other  property),  recapitalization,  stock  split,  reverse  stock  split,  rights  offering,  reorganization,  merger,  consolidation,  split-up, 
spin-off,  split-off,  combination,  subdivision,  repurchase,  or  exchange  of  Common  Stock  or  other  securities  of  the  Company, 
issuance of warrants or other rights to purchase Common Stock or other securities of the Company, or other similar corporate 
transaction  or  event  affects  the  Common  Stock  such  that  an  adjustment  is  determined  by  the  Committee  to  be  appropriate  to 
prevent the dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the 
Committee shall, in such mariner as it may deem equitable, adjust any or all of the (i) the number of shares and type of Common 
Stock  (or  the  securities  or  property)  that  thereafter  may  be  made  the  subject  of  Awards,  (ii)  the  number  of  shares  and  type  of 
Common Stock (or other securities or property) subject to outstanding Awards, (iii) the Grant Price of each outstanding Award, 
and (iv) the amount, if any, the Company pays for forfeited shares of Common Stock in accordance with Section 6.4;  provided 
however, that the number of shares of Common Stock (or other securities or property) subject to any Award shall always be a 
whole number. In lieu of the foregoing, if deemed 

 
 
 
 
appropriate, the Committee may make provision for a cash payment to the holder of an outstanding Award. Notwithstanding the 
foregoing, no such adjustment or cash payment may be made or authorized to the extent that such adjustment or cash payment 
would cause the Plan or any Stock Option to violate Section 422 of the Code. Such adjustments shall be made in accordance with 
the rules of any securities exchange, stock market, or stock quotation system to which the Company is subject.

Upon  the  occurrence  of  any  such  adjustment  or  cash  payment,  the  Company  shall  provide  notice  to  each  affected 
Participant  of  its  computation  of  such  adjustment  or  cash  payment,  which  shall  be  conclusive  and  shall  be  binding  upon  each 
such Participant.

ARTICLE 12
RECAPITALIZATION, MERGER AND CONSOLIDATION

12.1 No Effect on Company’s Authority. The existence of this Plan and Incentives granted hereunder shall 
not  affect  in  any  way  the  right  or  power  of  the  Company  or  its  shareholders  to  make  or  authorize  any  or  all  adjustments, 
recapitalizations, reorganizations, or other changes in the Company’s capital structure and its business, or any Change in Control, 
or  any  merger  or  consolidation  of  the  Company,  or  any  issuance  of  bonds,  debentures,  preferred  or  preference  stocks  ranking 
prior to or otherwise affecting the Common Stock or the rights thereof (or any rights, options, or warrants to purchase same), or 
the  dissolution  or  liquidation  of  the  Company,  or  any  sale  or  transfer  of  all  or  any  part  of  its  assets  or  business,  or  any  other 
corporate act or proceeding, whether of a similar character or otherwise.

12.2 Conversion of Incentives When Company Survives. Subject to any required action by the shareholders 
and except as otherwise provided by Section 12.4 hereof or as may be required to comply with Section 409A of the Code and the 
regulations  or  other  guidance  issued  thereunder,  if  the  Company  shall  be  the  surviving  or  resulting  corporation  in  any  merger, 
consolidation or share exchange, any Incentive granted hereunder shall pertain to and apply to the securities or rights (including 
cash, property, or assets) to which a holder of the number of shares of Common Stock subject to the Incentive would have been 
entitled.

12.3 Exchange  or  Cancellation  of  Incentives  When  Company  Does  Not  Survive.  Except  as  otherwise 
provided by Section 12.4 hereof or as may be required to comply with Section 409A of the Code and the regulations or other 
guidance issued thereunder, in the event of any merger, consolidation or share exchange pursuant to which the Company is not 
the  surviving  or  resulting  corporation,  there  shall  be  substituted  for  each  share  of  Common  Stock  subject  to  the  unexercised 
portions  of  outstanding  Incentives,  that  number  of  shares  of  each  class  of  stock  or  other  securities  or  that  amount  of  cash, 
property, or assets of the surviving, resulting or consolidated company which were distributed or distributable to the shareholders 
of the Company in respect to each share of Common Stock held by them, such outstanding Incentives to be thereafter exercisable 
for such stock, securities, cash, or property in accordance with their terms.

12.4 Cancellation of Incentives. Notwithstanding the provisions of Sections 12.2 and 12.3 hereof, and except 
as  may  be  required  to  comply  with  Section  409A  of  the  Code  and  the  regulations  or  other  guidance  issued  thereunder,  all 
Incentives granted hereunder may be canceled by the Company, in its sole discretion, as of the effective date of any Change in 
Control, merger, consolidation or share exchange, or any issuance of bonds, debentures, preferred or 

 
 
 
preference  stocks  ranking  prior  to  or  otherwise  affecting  the  Common  Stock  or  the  rights  thereof  (or  any  rights,  options,  or 
warrants to purchase same), or of any proposed sale of all or substantially all of the assets of the Company, or of any dissolution 
or liquidation of the Company, by either:

(a)

giving  notice  to  each  holder  thereof  or  his  personal  representative  of  its  intention  to  cancel  those 
Incentives for which the issuance of shares of Common Stock involved payment by the Participant for such shares and, 
permitting the purchase during the thirty (30) day period next preceding such effective date of any or all of the shares of 
Common Stock subject to such outstanding Incentives, including in the Board’s discretion some or all of the shares as to
which such Incentives would not otherwise be vested and exercisable; or

(b)

in the case of Incentives that are either (i) settled only in shares of Common Stock, or (ii) at the election 
of  the  Participant,  settled  in  shares  of  Common  Stock,  paying  the  holder  thereof  an  amount  equal  to  a  reasonable 
estimate of the difference between the net amount per share payable in such transaction or as a result of such transaction, 
and  the  price  per  share  of  such  Incentive  to  be  paid  by  the  Participant  (hereinafter  the  “Spread”),  multiplied  by  the 
number  of  shares  subject  to  the  Incentive.  In  cases  where  the  shares  constitute,  or  would  after  exercise,  constitute 
Restricted Stock, the Company, in its discretion may include some or all of those shares in the calculation of the amount 
payable  hereunder.  In  estimating  the  Spread,  appropriate  adjustments  to  give  effect  to  the  existence  of  the  Incentives 
shall be made, such as deeming the Incentives to have been exercised, with the Company receiving the exercise price 
payable  thereunder,  and  treating  the  shares  receivable  upon  exercise  of  the  Incentives  as  being  outstanding  in 
determining the net amount per share. In cases where the proposed transaction consists of the acquisition of assets of the 
Company, the net amount per share shall be calculated on the basis of the net amount receivable with respect to shares of 
Common  Stock  upon  a  distribution  and  liquidation  by  the  Company  after  giving  effect  to  expenses  and  charges, 
including but not limited to taxes, payable by the Company before such liquidation could be completed.

(c) An  Award  that  by  its  terms  would  be  fully  vested  or  exercisable  upon  a  Change  in  Control  will  be 

considered vested or exercisable for purposes of Section 12.4(a) hereof.

ARTICLE 13
LIQUIDATION OR DISSOLUTION

Subject to Section 12.4 hereof, in case the Company shall, at any time while any Incentive under this Plan shall be in 
force and remain unexpired, (i) sell all or substantially all of its property, or (ii) dissolve, liquidate, or wind up its affairs, then 
each Participant shall be entitled to receive, in lieu of each share of Common Stock of the Company that such Participant would 
have  been  entitled  to  receive  under  the  Incentive,  the  same  kind  and  amount  of  any  securities  or  assets  as  may  be  issuable, 
distributable, or payable upon any such sale, dissolution, liquidation, or winding up with respect to each share of Common Stock 
of the Company. If the Company shall, at any time prior to the expiration of any Incentive, make any partial distribution of its 
assets, in the nature of a partial liquidation, whether payable in cash or in kind (but excluding the distribution of a cash dividend 
payable out of earned surplus and designated as such) and an adjustment is determined by the Committee to be appropriate to 
prevent the dilution of the benefits or potential benefits 

 
 
 
intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, make such 
adjustment in accordance with the provisions of Article 11 hereof.

ARTICLE 14
INCENTIVES IN SUBSTITUTION FOR
INCENTIVES GRANTED BY OTHER ENTITIES

Incentives may be granted under the Plan from time to time in substitution for similar instruments held by employees, 
consultants  or  directors  of  a  corporation,  partnership,  or  limited  liability  company  who  become  or  are  about  to  become 
Employees, Consultants or Outside Directors of the Company or any Parent or Subsidiary as a result of a merger or consolidation 
of the employing corporation with the Company, the acquisition by the Company of equity of the employing entity, or any other 
similar transaction pursuant to which the Company becomes the successor employer. The terms and conditions of the substitute 
Incentives so granted may vary from the terms and conditions set forth in this Plan to such extent as the Committee at the time of 
grant may deem appropriate to conform, in whole or in part, to the provisions of the Incentives in substitution for which they are 
granted.

ARTICLE 15
MISCELLANEOUS PROVISIONS

15.1 Investment  Intent.  The  Company  may  require  that  there  be  presented  to  and  filed  with  it  by  any 
Participant  under  the  Plan,  such  evidence  as  it  may  deem  necessary  to  establish  that  the  Incentives  granted  or  the  shares  of 
Common Stock to be purchased or transferred are being acquired for investment and not with a view to their distribution.

confer upon any Participant any right with respect to continuance of employment by the Company or any Parent or Subsidiary.

determination,  or  interpretation  taken  or  made  in  good  faith  with  respect  to  the  Plan,  and  all  members  of  the  Board  and  the 
Committee, each officer of the Company, and each Employee of the Company acting on behalf of the Board or the Committee 
shall,  to  the  extent  permitted  by  law,  be  fully  indemnified  and  protected  by  the  Company  in  respect  of  any  such  action, 
determination, or interpretation.

be deemed to give any person any right to be granted an Award or any other rights except as may be evidenced by an Award 
Agreement, or any amendment thereto, duly authorized by the Committee and executed on behalf of the Company, and then only 
to the extent and upon the terms and conditions expressly set forth therein.

15.5 Compliance  With  Other  Laws  and  Regulations.  Notwithstanding  anything  contained  herein  to  the 
contrary, the Company shall not be required to sell or issue shares of Common Stock under any Incentive if the issuance thereof 
would constitute a violation by the Participant or the Company of any provisions of any law or regulation of any governmental 
authority or any national securities exchange or interdealer quotation system or other forum in 

 
 
 
 
 
which shares of Common Stock are quoted or traded (including without limitation Section 16 of the 1934 Act and Section 162(m) 
of the Code); and, as a condition of any sale or issuance of shares of Common Stock under an Incentive, the Committee may 
require such agreements or undertakings, if any, as the Committee may deem necessary or advisable to assure compliance with 
any such law or regulation. The Plan, the grant and exercise of Incentives hereunder, and the obligation of the Company to sell 
and deliver shares of Common Stock, shall be subject to all applicable federal and state laws, rules and regulations and to such 
approvals by any government or regulatory agency as may be required.

15.6 Tax Requirements. The Company or, if applicable, any Parent or Subsidiary (for purposes of this Section 
15.6, the term “Company” shall be deemed to include any applicable Parent or Subsidiary), shall have the right to deduct from all 
amounts paid in cash or other form in connection with the Plan, any Federal, state, local, or other taxes required by law to be 
withheld  in  connection  with  an  Award  granted  under  this  Plan.  The  Company  may,  in  its  sole  discretion,  also  require  the 
Participant  receiving  shares  of  Common  Stock  issued  under  the  Plan  to  pay  the  Company  the  amount  of  any  taxes  that  the 
Company is required to withhold in connection with the Participant’s income arising with respect to the Award. Such payments 
shall be required to be made when requested by Company and may be required to be made prior to the delivery of any certificate 
representing shares of Common Stock. Such payment may be made (i) by the delivery of cash to the Company in an amount that 
equals or exceeds (to avoid the issuance of fractional shares under (iii) below) the required tax withholding obligations of the 
Company; (ii) if the Company, in its sole discretion, so consents in writing, the actual delivery by the exercising Participant to the 
Company of shares of Common Stock that the Participant has not acquired from the Company within six (6) months prior to the 
date of exercise, which shares so delivered have an aggregate Fair Market Value that equals or exceeds (to avoid the issuance of 
fractional shares under (iii) below) the required tax withholding payment; (iii) if the Company, in its sole discretion, so consents 
in writing, the Company’s withholding of a number of shares to be delivered upon the exercise of the Stock Option, which shares 
so withheld have an aggregate fair market value that equals (but does not exceed) the required tax withholding payment; or (iv) 
any  combination  of  (i),  (ii),  or  (iii).  The  Company  may,  in  its  sole  discretion,  withhold  any  such  taxes  from  any  other  cash 
remuneration  otherwise  paid  by  the  Company  to  the  Participant.  The  Committee  may  in  the  Award  Agreement  impose  any 
additional tax requirements or provisions that the Committee deems necessary or desirable.

15.7 Assignability.  Incentive  Stock  Options  may  not  be  transferred,  assigned,  pledged,  hypothecated  or 
otherwise conveyed or encumbered other than by will or the laws of descent and distribution and may be exercised during the 
lifetime  of  the  Participant  only  by  the  Participant  or  the  Participant’s  legally  authorized  representative,  and  each  Award 
Agreement in respect of an Incentive Stock Option shall so provide. The designation by a Participant of a beneficiary will not 
constitute  a  transfer  of  the  Stock  Option.  The  Committee  may  waive  or  modify  any  limitation  contained  in  the  preceding 
sentences of this Section 15.7 that is not required for compliance with Section 422 of the Code.

Except  as  otherwise  provided  herein,  Nonqualified  Stock  Options  may  not  be  transferred,  assigned,  pledged, 
hypothecated or otherwise conveyed or encumbered other than by will or the laws of descent and distribution. The Committee 
may, in its discretion, authorize all or a portion of a Nonqualified Stock Option to be granted to a Participant on terms which 
permit transfer by such Participant to (i) the spouse (or former spouse), children or grandchildren of the Participant 

 
 
(“Immediate  Family  Members”),  (ii)  a  trust  or  trusts  for  the  exclusive  benefit  of  such  Immediate  Family  Members,  (iii)  a 
partnership  in  which  the  only  partners  are  (1)  such  Immediate  Family  Members  and/or  (2)  entities  which  are  controlled  by 
Immediate  Family  Members,  (iv)  an  entity  exempt  from  federal  income  tax  pursuant  to  Section  501(c)(3)  of  the  Code  or  any 
successor  provision,  or  (v)  a  split  interest  trust  or  pooled  income  fund  described  in  Section  2522(c)(2)  of  the  Code  or  any 
successor provision, provided that (x) there shall be no consideration for any such transfer, (y) the Award Agreement pursuant to 
which  such  Nonqualified  Stock  Option  is  granted  must  be  approved  by  the  Committee  and  must  expressly  provide  for 
transferability in a manner consistent with this Section, and (z) subsequent transfers of transferred Nonqualified Stock Options 
shall be prohibited except those by will or the laws of descent and distribution.

Following  any  transfer,  any  such  Nonqualified  Stock  Option  shall  continue  to  be  subject  to  the  same  terms  and 
conditions as were applicable immediately prior to transfer, provided that for purposes of Articles 8, 9, 11, 13 and 15 hereof the 
term “Participant” shall be deemed to include the transferee. The events of Termination of Service shall continue to be applied 
with respect to the original Participant, following which the Nonqualified Stock Options shall be exercisable or convertible by the 
transferee only to the extent and for the periods specified in the Award Agreement. The Committee and the Company shall have 
no  obligation  to  inform  any  transferee  of  a  Nonqualified  Stock  Option  of  any  expiration,  termination,  lapse  or  acceleration  of 
such Stock Option. The Company shall have no obligation to register with any federal or state securities commission or agency 
any Common Stock issuable or issued under a Nonqualified Stock Option that has been transferred by a Participant under this 
Section 15.7.

15.9 Legend.  Each  certificate  representing  shares  of  Restricted  Stock  issued  to  a  Participant  shall  bear  the 
following legend, or a similar legend deemed by the Company to constitute an appropriate notice of the provisions hereof (any 
such certificate not having such legend shall be surrendered upon demand by the Company and so endorsed):

On the face of the certificate:

“Transfer of this stock is restricted in accordance with conditions printed on the reverse of this 
certificate.”

On the reverse:

“The  shares  of  stock  evidenced  by  this  certificate  are  subject  to  and  transferable  only  in 
accordance with that certain Lung Therapeutics, Inc. 2013 Long-Term Incentive Plan, a copy 
of  which  is  on  file  at  the  principal  office  of  the  Company  in  Austin,  Texas.  No  transfer  or 
pledge of the shares evidenced hereby may be made except in accordance with and subject to 
the provisions of said Plan. By acceptance of this certificate, any holder, transferee or pledgee 
hereof agrees to be bound by all of the provisions of said Plan.”

 
 
The  following  legend  shall  be  inserted  on  a  certificate  evidencing  Common  Stock  issued  under  the  Plan  if  the  shares 

were not issued in a transaction registered under the applicable federal and state securities laws:

“Shares  of  stock  represented  by  this  certificate  have  been  acquired  by  the  holder  for 
investment and not for resale, transfer or distribution, have been issued pursuant to exemptions 
from the registration requirements of applicable state and federal securities laws, and may not 
be offered for sale, sold or transferred other than pursuant to effective registration under such
laws,  or  in  transactions  otherwise  in  compliance  with  such  laws,  and  upon  evidence 
satisfactory to the Company of compliance with such laws, as to which the Company may rely 
upon an opinion of counsel satisfactory to the Company.”

A copy of this Plan shall be kept on file in the principal office of the Company in Austin, Texas.

Compensation Recovery Policy

Exhibit 97.1

This Compensation Recovery Policy (this “Policy”) is adopted by Aileron Therapeutics, Inc. (the “Company”) in accordance with Nasdaq Listing Rule 
5608 (“Rule 5608”).  This Policy is effective as of October 2, 2023 (the “Effective Date”).

1.

Definitions

(a) “Accounting Restatement” means a requirement that the Company prepare an accounting restatement due to the material noncompliance of 
the Company with any financial reporting requirement under the U.S. federal securities laws, including any required accounting restatement to correct an 
error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement 
if  the  error  were  corrected  in  the  current  period  or  left  uncorrected  in  the  current  period.  Changes  to  the  Company’s  financial  statements  that  do  not 
represent  error  corrections  are  not  an  Accounting  Restatement,  including:  (A)  retrospective  application  of  a  change  in  accounting  principle;  (B) 
retrospective  revision  to  reportable  segment  information  due  to  a  change  in  the  structure  of  the  Company’s  internal  organization;  (C)  retrospective 
reclassification due to a discontinued operation; (D) retrospective application of a change in reporting entity, such as from a reorganization of entities under 
common control; and (E) retrospective revision for stock splits, reverse stock splits, stock dividends or other changes in capital structure.

(b) “Committee” means the Compensation Committee of the Company’s Board of Directors (the “Board”).

(c) “Covered  Person”  means  a  person  who  served  as  an  Executive  Officer  at  any  time  during  the  performance  period  for  the  applicable 

Incentive-Based Compensation.

(d) “Erroneously Awarded Compensation” means the amount of Incentive-Based Compensation that was Received that exceeds the amount of 
Incentive-Based Compensation that otherwise would have been Received had the amount of Incentive-Based Compensation been determined based on the 
restated amounts, computed without regard to any taxes paid by the Covered Person or by the Company on the Covered Person’s behalf. For Incentive-
Based  Compensation  based  on  stock  price  or  total  shareholder  return,  where  the  amount  of  Erroneously  Awarded  Compensation  is  not  subject  to 
mathematical recalculation directly from the information in an Accounting Restatement, the amount of Erroneously Awarded Compensation will be based 
on  a  reasonable  estimate  by  the  Committee  of  the  effect  of  the  Accounting  Restatement  on  the  stock  price  or  total  shareholder  return  upon  which  the 
Incentive-Based Compensation was Received.  The Company will maintain documentation of the determination of that reasonable estimate and provide 
such documentation to Nasdaq.

(e) “Executive Officer” means the Company’s officers as defined in Rule 16a-1(f) under the Securities Exchange Act of 1934, as amended. 

(f) “Financial Reporting Measures” means (A) measures that are determined and presented in accordance with the accounting principles used 
in preparing the Company’s financial statements, and any measures that are derived wholly or in part from such measures (whether or not such measures 
are presented within the Company’s financial statements or included in a filing made with the U.S. Securities and Exchange Commission), (B) stock price 
and (C) total shareholder return.  

(g) “Incentive-Based Compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of 

a Financial Reporting Measure.

(h) Incentive-Based Compensation is deemed to be “Received” in the Company’s fiscal period during which the Financial Reporting Measure 
specified in the applicable Incentive-Based Compensation award is attained, even if the payment or grant of the Incentive-Based Compensation occurs after 
the end of that period or is subject to additional time-based vesting requirements.

(i) “Recovery Period” means the three completed fiscal years immediately preceding the earlier of: (A) the date the Board, a committee of the 
Board,  or  the  officer  or  officers  of  the  Company  authorized  to  take  such  action  if  Board  action  is  not  required,  concludes,  or  reasonably  should  have 
concluded, that the Company is required to prepare an Accounting Restatement; or (B) the date a court, regulator, or other legally authorized body directs 
the  Company  to  prepare  an  Accounting  Restatement.  In  addition,  if  there  is  a  change  in  the  Company’s  fiscal  year  end,  the  Recovery  Period  will  also 
include any transition period to the extent required by Rule 5608.

2.

Recovery of Erroneously Awarded Compensation

Subject to the terms of this Policy and the requirements of Rule 5608, if the Company is required to prepare an Accounting Restatement, the 
Company will attempt to recover, reasonably promptly from each Covered Person, any Erroneously Awarded Compensation that was Received by such 
Covered Person during the Recovery Period pursuant to Incentive-Based Compensation that is subject to this Policy.

3.

Interpretation and Administration

(a) Role  of  the  Committee.    This  Policy  will  be  interpreted  by  the  Committee  in  a  manner  that  is  consistent  with  Rule  5608  and  any  other 
applicable law and will otherwise be interpreted in the business judgment of the Committee.  All decisions and interpretations of the Committee will be 
final and binding. 

(b) Compensation  Not  Subject  to  this  Policy.    This  Policy  does  not  apply  to  Incentive-Based  Compensation  that  was  Received  before  the 
Effective  Date.  With  respect  to  any  Covered  Person,  this  Policy  does  not  apply  to  Incentive-Based  Compensation  that  was  Received  by  such  Covered 
Person before beginning service as an Executive Officer.

(c) Determination of Means of Recovery. Subject to the requirement that recovery be made reasonably promptly, the Committee will determine 
the appropriate means of recovery, which may vary between Covered Persons or based on the nature of the applicable Incentive-Based Compensation, and 
which may involve, without limitation, establishing a deferred repayment plan or setting off against current or future compensation otherwise payable to 
the Covered Person.  Recovery of Erroneously Awarded Compensation will be made without regard to income taxes paid by the Covered Person or by the 
Company on the Covered Person’s behalf in connection with such Erroneously Awarded Compensation. 

(d) Determination  That  Recovery  is  Impracticable.  The  Company  is  not  required  to  recover  Erroneously  Awarded  Compensation  if  a 
determination is made by the Committee that either (A) after the Company has made and documented a reasonable attempt to recover such Erroneously 
Awarded Compensation, the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered or (B) recovery 
of such Erroneously Awarded Compensation would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to 
employees of the registrant, to fail to meet the requirements of Section 401(a)(13) or 411(a) of the Internal Revenue Code and regulations thereunder.

(e) No  Indemnification  or  Company-Paid  Insurance.  The  Company  will  not  indemnify  any  Covered  Person  against  the  loss  of  Erroneously 
Awarded Compensation and will not pay or reimburse any Covered Person for the purchase of a third-party insurance policy to fund potential recovery 
obligations.

(f) Interaction  with  Other  Clawback  Provisions.  The  Company  will  be  deemed  to  have  recovered  Erroneously  Awarded  Compensation  in 
accordance  with  this  Policy  to  the  extent  the  Company  actually  receives  such  amounts  pursuant  to  any  other  Company  policy,  program  or  agreement, 
pursuant to Section 304 of the Sarbanes-Oxley Act or otherwise.

(g) No  Limitation  on  Other  Remedies.  Nothing  in  this  Policy  will  be  deemed  to  limit  the  Company’s  right  to  terminate  employment  of  any 
Covered Person, to seek recovery of other compensation paid to a Covered Person, or to pursue other rights or remedies available to the Company under 
applicable law.

Adopted by the Board on November 28, 2023.
