We are a clinical stage biopharmaceutical company with a history of financial losses. We expect to continue to incur significant losses for the foreseeable future
and may never achieve or maintain cash self-sufficiency or profitability, which could result in a decline in the market value of our common stock.

We  expect  the  results  of  the  go/no  go  interim  analysis  decision  from  our  independent  data  monitoring  committee  with  respect  to  the  Phase  2b  portion  of  our
ongoing Validive clinical trial by the end of March 2023. A negative decision would require us to refocus our development efforts on our other product candidates
and could result in a decline in the market value of our common stock.

Funds raised to date are not sufficient to 1) assuming a positive result of the go/no go interim analysis decision anticipated by the end of March 2023, complete the
Phase 3 portion of our ongoing Validive Phase 2b/3 (“VOICE”) clinical program, including, if required, completing a second Phase 3 confirmatory clinical trial;
2) continue the clinical development of camsirubicin through and beyond our ongoing Phase 1b dose escalation clinical trial; 3) support further development of
MNPR-101 for radiopharmaceutical use in advanced cancers; or 4) support continued development of MNPR-202 and related compounds. If we are unable to
raise enough funds within the next 12 months from the sale of our common stock or other financing efforts, or conclude a strategic agreement or collaboration
such as out-licensing Validive or other product candidates, or entering into a clinical or commercial partnership, we will likely have to terminate one or more
programs. There can be no assurance that we will be able to secure such financing or find a suitable development partner on satisfactory terms.

We do not have and may never have any approved products on the market. Our business is highly dependent upon receiving marketing approvals from various
U.S. and international governmental agencies and would be severely harmed if we are not granted approvals to manufacture and sell our product candidates.

Our  clinical  trials  may  not  yield  sufficiently  conclusive  results  for  regulatory  agencies  to  approve  the  use  of  our  products,  which  would  adversely  affect  our
financial condition.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals will be delayed or prevented,
which would materially delay our program schedules and adversely affect our financial condition.

If we or our licensees, development collaborators, or suppliers are unable to manufacture our products in sufficient quantities or at defined quality specifications,
or are unable to obtain regulatory approvals for the manufacturing facility, we may be unable to develop and/or meet demand for our products and lose time to
market and potential revenues.

We rely on qualified third parties to conduct our active pharmaceutical ingredient manufacturing, our drug product manufacturing, non-clinical studies, and our
clinical trials. If these third parties do not or cannot successfully carry out their contractual duties and meet expected deadlines or performance goals, the initiation
or conduct of our clinical trials would be delayed and we may be unable to obtain regulatory approval for, or commercialize, our current product candidates or
any future products, and our financial condition would be adversely affected.

The  Russia-Ukraine  war,  and  resulting  sanctions  against  Russia  and  Russian  entities,  and  Russian  reduction  in  gas  shipments  to  the  EU  and  other  allies,  have
increased  fuel  costs,  reduced  access  to  critical  supplies  and  may  cause  shipping  delays.    The  broader  economic,  trade  and  financial  market  consequences  are
uncertain at this time, which may increase the cost of supplies for our clinical materials, may delay the manufacture of our clinical materials, may increase costs of
other goods and services or make it more difficult or costly to raise additional financing, any of which could cause an adverse effect on our clinical programs and
on our financial condition.

Market variables, such as inflation of product costs, labor rates and fuel, freight and energy costs, as well as geopolitical events could likely cause us to suffer
significant increases in our operating and administrative expenses.

Unstable  market  and  economic  conditions,  such  as  the  recent  volatility  in  the  markets  due  to  concerns  about  bank  stability  and  economic  challenges  due  to
inflation, may have serious adverse consequences on our ability to raise funds, which may cause us to delay, restructure or cease our operations.

The effects of economic and political pressure to lower pharmaceutical prices are a major threat to the economic viability of new research-based pharmaceutical
products, and any significant decrease in drug prices could materially and adversely affect the financial appeal of our  products and investment prospects.

We face significant competition from other biotechnology and pharmaceutical companies, and from research-based academic medical institutions, in our targeted
medical  indications,  and  our  operating  results  would  be  adversely  affected  if  we  fail  to  compete  effectively.  Many  competitors  have  greater  organizational
capabilities  in  our  industry,  much  higher  available  capital  resources,  and  established  marketing  resources  and  sales  in  the  targeted  markets.  Competition  and
technological change may make our product candidates obsolete or non-competitive.

The termination of third-party licenses would adversely affect our rights to important compounds or technologies which are essential to develop and market our
products.

If we and our third-party licensors do not obtain and preserve protection for our respective intellectual property rights, our competitors may be able to develop and
market competing drugs, which would adversely affect our financial condition.

.If  we  lose  key  management  leadership,  and/or  the  expertise  and  experience  of  our  scientific  personnel,  and  if  we  cannot  recruit  qualified  employees  or  other
highly qualified and experienced personnel for future requirements, we would be at risk to experience significant program delays and increased compensation and
operational costs, and our business would be materially disrupted.

The  long-term  effects  of  COVID-19  are  highly  uncertain,  and  their  scope  and  impact  could  have  a  substantial  negative  bearing  on  our  business,  financial
condition, operating results, stock price and ability to raise additional funds.

Item 1. Business

PART I

You should read the following discussion in conjunction with our financial statements as of December 31, 2022, and the notes to such financial statements included

elsewhere in this Annual Report on Form 10-K.

Overview

We are a clinical stage biopharmaceutical company focused on developing proprietary therapeutics designed to extend life or improve quality of life for cancer patients.
We are building a drug development pipeline through the licensing and acquisition of therapeutics in late preclinical and clinical development stages. We leverage our scientific
and clinical experience to help reduce the risk and accelerate the clinical development of our drug product candidates.

During 2022, we expanded the number of clinical trial sites in our global Phase 2b/3 clinical trial of our lead product candidate, Validive®  (clonidine  hydrochloride
mucobuccal  tablet;  clonidine  HCI  MBT),  for  the  prevention  of  chemoradiotherapy  (“CRT”)-induced  severe oral  mucositis  (“SOM”)  in  patients  with  oropharyngeal cancer
(“VOICE” trial). We currently have active sites in the U.S., Spain, France, Germany and Poland and have completed enrollment of the Phase 2b portion of the clinical trial with
a go/no go interim analysis decision from our independent data monitoring committee anticipated by the end of March 2023. We also continued enrolling in our U.S.-based
open-label, Phase 1b clinical trial of camsirubicin for the treatment of advanced soft tissue sarcoma (“ASTS”). We also, in collaboration with our partner, NorthStar Medical
Radioisotopes, LLC, continue to move forward with the development of MNPR-101 for radiopharmaceutical use in advanced cancers.  Finally, we continue to develop MNPR-
202, an analog of camsirubicin designed to potentially treat doxorubicin- and camsirubicin-resistant cancers, which is being tested in preclinical models by our collaborator, the
Cancer Science Institute of Singapore at the National University of Singapore.

To  complete  the  VOICE  clinical  program,  including,  if  required,  completing  a  second  Phase  3  confirmatory  clinical  trial,  we  will  require  additional  funding  in  the
millions or tens of millions of dollars (depending on if we have consummated a collaboration or partnership or neither for Validive) which we are planning to pursue within the
next 12 months. We also require additional funding to continue to develop camsirubicin through and beyond our ongoing Phase 1b clinical trial and to further fund our current
and future product pipeline.

Our Product Pipeline

 Our Product Candidates

Validive (clonidine hydrochloride mucobuccal tablet; clonidine HCI MBT)

Validive is designed to be used prophylactically to prevent SOM in patients undergoing CRT for oropharyngeal cancer (“OPC”). SOM is a painful and debilitating
inflammation and ulceration of the mucous membranes lining the oral cavity and oropharynx in response to chemoradiation. The majority of patients receiving CRT to treat
their OPC develop SOM, which remains one of the most common and devastating side effects of treatment in this indication. The potential clinical benefits to preventing SOM
in patients include: reduced treatment discontinuations leading to potentially improved overall survival outcomes; reduced mouth and throat pain avoiding the need for feeding
tube  intervention;  decreased  long-term  and  often  permanent  debilitation  arising  from  swallowing  difficulties,  neck  and  throat  spasms,  and  lung  complications  due  to  food
aspiration;  and  decreased  reliance  on  pain  medication.  Our  mucobuccal  tablet  (“MBT”)  formulation  is  a  novel  delivery  system  for  clonidine  that  allows  for  prolonged  and
enhanced local delivery of drug in the regions of mucosal radiation damage in patients with OPC. Validive has been granted fast track designation in the U.S., orphan drug
designation in the EU, and has global intellectual property patent protection through mid-2029 not accounting for possible patent extensions.

In  September  2017,  we  exercised  an  option  to  license  Validive  from  Onxeo  S.A.,  the  company  that  developed  Validive  through  its  Phase  2  clinical  trial.  In  the
completed Phase 2 clinical trial, Validive demonstrated clinically meaningful efficacy signals within the 64-patient OPC population randomized to placebo, Validive 50 µg dose
and Validive 100 µg dose. The absolute incidence of SOM in OPC patients who received a dose of Validive 100 µg once per day was reduced by 26.3% (incidence rate of
65.2% in placebo, 45.0% in Validive 50 µg group, and 38.9% in Validive 100 µg group). The median time to onset of SOM was 37 days in the placebo cohort; 45 days in the
Validive 50 µg cohort and no median time of onset was reached in the Validive 100 µg group since fewer than half of this cohort of patients developed SOM. There was also a
37.8% reduction in the median duration of the SOM for the Validive 100 µg group versus placebo (41.0 days placebo group, 34.0 days Validive 50 µg group, and 25.5 days
Validive 100 µg group) in patients that developed SOM. Median duration of SOM across all patients, inclusive of both those that did and did not develop SOM, was 17 days in
the placebo group and 0 days in each of the Validive 50 and 100 µg groups. A positive dose response was seen in each of these three clinical endpoints. Additionally, patients in
the Validive cohorts in the Phase 2 clinical trial demonstrated a safety profile similar to that of placebo. Onxeo’s promising preclinical studies and Phase 2 clinical trial have
informed the design and conduct of what we believe will be an effective Phase 2b/3 and, if required, second confirmatory Phase 3 clinical program.

Table of Contents

In February 2021, we dosed the first patient in our Phase 2b/3 VOICE trial. In August 2021, we successfully reached our original target of 20 activated clinical trial
sites for the Phase 2b portion of the 2b/3 Validive® VOICE trial, and in September 2021 we received authorization to proceed with the VOICE clinical trial in multiple countries
in Europe. In 2022, we completed enrollment of the Phase 2b portion of the VOICE trial and commenced enrolling the Phase 3 portion. As of March 10, 2023, we have 81
clinical sites activated and enrolling patients in the U.S. and Europe. To be prepared for a positive go/no-go decision based on the interim analysis, anticipated to occur by the
end  of  March  2023,  we  continue  to  activate  additional  sites  globally.  To  complete  the  VOICE  clinical  program,  including,  if  required,  completing  a  second  Phase  3
confirmatory clinical trial, we will require additional funding in the millions or tens of millions of dollars (depending on if we have consummated a collaboration or partnership
or neither for Validive), which we are planning to pursue within the next 12 months.

SOM typically arises in the immune tissue at the back of the tongue and throat, which comprise the oropharynx, and consists of acute severe tissue damage and pain
that prevents patients from swallowing, eating and drinking. Validive stimulates the alpha-2 adrenergic receptor (alpha-2AR) on macrophages (white blood cells present in the
immune tissues of the oropharynx) suppressing pro-inflammatory cytokine expression. Validive exerts its effects locally in the oral cavity and oropharynx over a prolonged
period of time through its unique MBT formulation. Patients who develop SOM are also at increased risk of developing late onset toxicities, including trismus (jaw, neck, and
throat spasms), dysphagia, and lung complications, which are often irreversible and lead to increased hospitalization and the need for further interventions sometimes years after
completion of CRT. We believe that the prevention of SOM by Validive will have the potential to reduce treatment discontinuation and/or treatment delays potentially leading to
improved survival outcomes and reducing or eliminating these long-term morbidities resulting from CRT.

The OPC target population for Validive is the most rapidly growing segment of head and neck cancer (“HNC”) patients, with an estimated greater than 40,000 new
cases of OPC in the U.S alone in 2023. The growth in OPC is driven by the increasing prevalence of oral human papilloma virus (“HPV”) infections in the U.S. and around the
world. Despite the availability of a pediatric/adolescent HPV vaccine, the rate of OPC incidence in adults is not anticipated to be materially reduced for decades due to low
adoption  of  the  vaccine  to  date. As  a  result,  the  incidence  of  HPV-driven  OPC  is  projected  to  increase  for  years  to  come  and  will  continue  to  represent  a  clinical  need  for
Validive for the prevention of CRT-induced SOM in patients with OPC since CRT is the standard of care treatment, and we anticipate that radiation will remain an important
treatment modality for these patients for years to come.

Validive  is  an  MBT  of  clonidine.  The  MBT  formulation  was  developed  to  enhance  drug  delivery  to  the  oral  mucosa  while  minimizing  systemic  absorption.  The
Validive tablet is tasteless and odorless and is self-administered once daily by affixing it to the outside of the patient’s upper gum where it dissolves slowly over a period of
several hours, resulting in the extended release of clonidine into the oral cavity and oropharynx, the sites of SOM following CRT for OPC. Validive treatment begins on the first
day of CRT and continue daily through the last day of radiation.

The majority of patients receiving CRT to treat their OPC develop SOM, which is one of the most common and devastating side effects of treatment in this indication.

We believe Validive has the potential to address several critical elements that affect SOM patients, including:

Reduction in the incidence of SOM. SOM can increase the risk of acute and chronic comorbidities, including dysphagia, trismus and lung complications, which are
often irreversible and lead to increased hospitalization and the need for additional interventions. In a Phase 2 clinical trial, the OPC patient cohort treated with Validive
100 µg demonstrated a reduction in the absolute incidence of SOM compared to placebo of 26.3% (incidence rate of 65.2% in placebo, 45.0% in Validive 50 µg group,
38.9% in Validive 100 µg group). A reduced incidence of SOM in OPC patients may lower the risk of acute and chronic comorbidities, and improve clinical outcomes
and quality of life.

Delay in the time to onset of SOM. SOM can cause cancer treatment delay and/or discontinuation, which seriously impacts overall survival outcomes. In the Phase 2
clinical trial, OPC patients had a time to onset of SOM of 37 days in the placebo cohort; 45-day time to onset of SOM in the Validive 50 µg cohort; and a median time
was not reached in the Validive 100 µg group as fewer than half of the patients developed SOM. Prolonging time to onset of SOM typically leads to fewer missed CRT
treatments, resulting in improved overall survival outcomes.

7

 
 
 
 
 
 
 
 
 
Table of Contents

Decrease in the duration of SOM. Longer duration of SOM leads to a higher risk of the need for parenteral nutrition and lower quality of life. SOM patients experience
difficulty  or  inability  to  drink  and/or  eat,  and  difficulty  in  swallowing  often  results  in  malnourishment  and  feeding  tube  intervention.  The  Phase  2  clinical  trial  data
demonstrated a 15.5-day reduction (by 37.8%) in the duration of SOM for patients treated with Validive 100 µg (41-day median duration with placebo, 34 days with the
Validive 50 µg group, and 25.5 days for the Validive 100 µg group) in patients that developed SOM. Median duration across all patients, inclusive of both those that did
and did not develop SOM, was 17 days in the placebo group and 0 days in each of the Validive 50 ug and 100 µg groups. Reduced duration of SOM has the capacity to
result in lower risk of malnourishment and feeding tube intervention, and fewer treatment terminations/delays.

While not designed by us, Onxeo’s promising preclinical studies and Phase 2 clinical trial have informed the design and conduct of what we believe will be an effective

Phase 2b/3 VOICE clinical trial.

In  response  to  COVID-19  and  its  effects  on  clinical  trials,  in  2020,  we  adjusted  our  clinical  development  plan  accordingly  to  fit  what  is  feasible  in  the  current
environment. We simplified the design of the previously planned Phase 3 clinical trial for Validive for the prevention of CRT-induced se vere oral mucositis in patients with
oropharyngeal cancer (“VOICE”), to a seamless Phase 2b/3 design. This design is based on a binary primary endpoint, incidence of SOM, and minimizes touch points with the
clinical  trial  sites  and  patients.  Validive  is  a  once  daily  self-administered  mucoadhesive  tablet  which  can  be  taken  in  the  patient’s  home  setting.  The  VOICE  trial
(NCT04648020)  is  a  randomized,  placebo-controlled  and  double  blinded  global  clinical  trial  with  trial  sites  in  the  U.S.,  Spain,  France,  Germany  and  Poland.  In  2022,  we
completed enrollment of the Phase 2b portion of the VOICE trial and commenced enrollment in the Phase 3 portion. As of March 10, 2023, we have 81 clinical sites activated
and enrolling patients in the U.S. and Europe.

The blinded interim analysis of clinical data from the Phase 2b patient cohort of the trial, to be performed by an independent data monitoring committee, will be used to
guide  us  as  to  whether  or  not  to  continue  enrolling  the  Phase  3  portion  of  the  trial.  This  analysis  should  be  completed  and  reported  out  by  the  end  of  March  2023.  To  be
prepared for a positive go/no-go decision based on the interim analysis, we continue to activate additional sites globally. The entire trial has been designed to enroll up to 260
evaluable patients. This modification in design allowed us to activate and commence dosing the VOICE trial in early 2021 without requiring near-term financing. If the interim
analysis  results  in  a  no-go  decision,  we  would  need  to  reconsider  our  efforts  with  respect  to  Validive  and  refocus  our  development  efforts  on  our  other  product  candidates
Because the interim analysis is being performed by an independent data monitoring committee, we do not know what the results will be as of the date of this Annual Report.

Assuming a positive result of the go/no go interim analysis decision anticipated by the end of March 2023, to complete the Phase 3 portion of the VOICE clinical
program,  including,  if  required,  completing  a  second  Phase  3  confirmatory  clinical  trial,  we  will  require  additional  funding  in  the  millions  or  tens  of  millions  of  dollars
(depending on if we have consummated a collaboration or partnership or neither for Validive), which we are planning to pursue within the next 12 months. Validive has been
granted  fast  track  designation  in  the  U.S.,  orphan  drug  designation  in  the  EU,  and  has  global  intellectual  property  patent  protection  through  mid-2029  not  accounting  for
possible patent extensions.

Validive U.S. Market Opportunity

The  incidence  of  HNC  (all  anatomical  types,  including  larynx,  oral  cavity,  oropharynx,  etc.)  in  the  U.S.  was  estimated  to  be  approximately  65,630  cases  in  2020
(American Society of Clinical Oncology, cancer.net). The most rapidly growing type of HNC is OPC. The oropharynx is comprised largely of immune tissue and includes the
soft palate, the base (rear one third) of the tongue, and the tonsils. In the U.S., the incidence of OPC is estimated to be greater than 40,000 cases in 2023. The majority of these
OPC patients (approximately 70%) are human papilloma virus positive (“HPV+”). The incidence of OPC is also increasing in the rest of the world (>30% of HNC), with >50%
of all OPC being HPV+. While certain types of HNC have been in decline in the U.S., such as laryngeal cancer as a result of a reduction in the smoking population, the total
incidence of HNC has been growing steadily primarily due to OPC. The increase in OPC is directly associated with increased infection with the human papilloma virus. The
incidence of HPV+ OPC has outpaced the incidence of HPV– HNC by 4-5-fold over the past decade. This trend of HPV+ OPC driving an increase in overall HNC is expected
to continue for some time as the relatively recent introduction of a vaccine designed to prevent the transfer and colonization with HPV is only effective if administered prior to
infection, and until October 2018, it was only recommended for those under the age of 26 (newer U.S. Food and Drug Administration (“FDA”) guidelines include those up to
age 45). Even for those under the age of 26 who are eligible for the vaccine, oral HPV infections are predicted to increase due to the lack of adequate use of HPV vaccinations.
Approximately 50% of eligible females and 33% of eligible males are presently being vaccinated.

Most OPC is caused by the HPV16 strain, with virus detectable in the tumor. More than 3% of adult men and 1% of adult woman have HPV16 detectable in their
saliva at any one time. The virus is transmitted through sexual contact and CDC estimates 10% of men and 3.6% of women in the U.S. have an active oral HPV infection. The
latency period for that proportion that do go on to develop HPV+ OPC is 15-20+ years. This HPV+ OPC population is expected to be a long-term driver of the incidence of
OPC, and the resultant SOM associated with what is frequently curative therapy for this serious malignancy.

In previous studies describing SOM in OPC patients receiving the CRT regimen we are using in our VOICE clinical program, patients had a SOM incidence rate of 55-
90%  across  studies.  In  the  Validive  Phase  2  trial,  the  incidence  of  SOM  in  OPC  patients  receiving  placebo  was  65.2%  (see  “Validive Phase 2 Clinical Trial Data”  section
below). Currently there is no way to predict which patients will develop SOM, so any active preventive treatment for SOM will likely be used in most OPC patients receiving
CRT. With the consistently growing incidence of OPC as a result of the human papillomavirus, there is the potential for a substantial and growing market for Validive.

Validive Mechanism of Action

Validive is designed to deliver high local concentrations of clonidine, an agonist of alpha-2AR, to the oral cavity and oropharynx, the site of irradiation in the treatment
of OPC. In the oropharynx, alpha-2AR is expressed on macrophages, immune cells that produce inflammatory cytokines, the molecules that are responsible for the development
of SOM, in response to CRT. Several published clinical reports have demonstrated that chemoradiation treatment substantially increased salivary cytokine levels and a recent
study demonstrated that these were positively associated with the formation of SOM in patients with head and neck cancer. Patients with HPV+ OPC demonstrate an increased
accumulation of macrophages in the tumor microenvironment compared to patients with OPC that were negative for human papilloma virus (“HPV–”), thus further priming
HPV+  OPC  patients  for  the  development  of  SOM.  The  alpha-2AR  regulates  the  expression  of  cytokines  by  macrophages,  and  clonidine  reduces  this  cytokine  production.
Macrophages  are  the  primary  immune  cells  in  the  oropharynx  that  express  alpha-2AR,  making  clonidine’s  mechanism  of  cytokine  suppression  macrophage  selective  and
distinct from the mechanism of other anti-inflammatory drugs. Further, Validive delivers clonidine to the mucosal surface, the site most affected by chemoradiation treatment in
OPC.  This  results  in  high  salivary  concentrations  of  clonidine,  minimizing  systemic  absorption,  and  allowing  for  maximal  exposure  the  at-risk  oral  mucosa  and  the  OPC
microenvironment to drug. Preclinical studies and a Phase 2 clinical trial of Validive have provided data that support Validive’s mechanism of action and therapeutic potential
for reducing the incidence of SOM in patients with OPC, improving oral mucositis-related symptoms, and decreasing CRT-related adverse events, while exhibiting a favorable
safety profile and high compliance rate in patients.

Validive Phase 2 Clinical Trial Data

In  October  2015,  the  results  from  an  international  Phase  2  clinical  trial  of  Validive  were  announced,  demonstrating  promising  signs  of  clinical  activity  and  safety
compared to placebo. The trial enrolled 183 HNC patients and was conducted in more than thirty centers in Europe and the United States. Patients who had undergone surgical
resection of their head and neck cancer with curative intent and who were planned to receive at least 50 Gray (Gy) of radiation in combination with chemotherapy, regardless of
anatomical location of disease, were included in this study. This global, multi-center, double-blind, randomized, placebo-controlled, three-arm study (NCT01385748) compared
the efficacy and safety of Validive 50 µg and 100 µg to placebo in patients with HNC receiving CRT. Of the 183 HNC patients, 64 had OPC (placebo = 24, Validive 50 µg =
21, Validive 100 µg = 19). Validive and placebo were administered once daily beginning 1 to 3 days prior to CRT and continuing until the end of chemoradiation.

We believe the Phase 2 clinical trial data support the development of Validive for the prevention of SOM in OPC patients. The analysis of OPC patients in this study

showed:

●

The incidence of SOM (primary endpoint) was reduced by 26.3% (40% relative to placebo) in OPC patients treated with Validive 100 µg (p=0.09, a meaningful
trend but not statistically significant). 65.2% of OPC patients on placebo experienced SOM compared to only 38.9% of OPC patients on Validive 100 µg.

■ Incidence of SOM in OPC Patients

Patients on Validive experienced a delay in the time to onset of SOM. Patients receiving placebo experienced a median time to onset of SOM of 37 days; patients
receiving Validive (50 µg one per day) experienced a 45-day median time to onset of SOM; and patients receiving Validive (100 µg once per day) did not reach a
median time to onset. A comparison of hazards for time to onset demonstrated that patients that received Validive 100 µg had a hazard ratio (HR)=0.48 compared
to placebo.

Patients receiving Validive experienced a decrease in the median duration of SOM. In patients that developed SOM, a 15.5-day reduction (by 37.8%) in the
median duration of SOM was observed in patients treated with Validive 100 µg (41-day median duration with placebo, 34 days in the Validive 50 µg group, and
25.5 days in the Validive 100 µg group). Median duration across all patients, inclusive of both those that did and did not develop SOM, was 17 days in the
placebo group and 0 days in each of the Validive 50 and 100 µg groups.

Severe drinking, eating, and speaking limitations due to mouth and throat soreness (“MTS”) score were also reduced in the Validive 100 µg treated cohort.

Improvements in other indicators of clinical benefit, including decreased weight loss, decreased opiate use and increased cumulative dose of radiation received,
strongly favored the Validive 100 µg treated group.

A dose response was observed with the Validive 100 µg dose, demonstrating a trend toward superiority over the Validive 50 µg dose as well as placebo.
Individual patient-level data supports advancing the Validive 100 µg dose into Phase 2b/3.

Individual Patient Data Showing Incidence, Time to Onset, and Duration of SOM in OPC patients
Treated with Placebo and Two Different Doses of Validive (50 and 100 µg/day)

For the full 183-patient Phase 2 population, which included various types of head and neck cancer such as oral and laryngeal cancer in addition to OPC, the incidence
of SOM was lower in patients treated with Validive (45.3% when the 50 and 100 µg dose groups were pooled together) than in patients receiving placebo (60.0%) (p = 0.064).
Additionally, Validive was very well tolerated, with the occurrence of adverse events of any type or grade being similar between placebo and Validive treated groups. Patients
treated with Validive experienced less nausea and dysphagia compared to placebo. No clinically meaningful decreases in systolic blood pressure or diastolic blood pressure
were noted between the placebo and Validive arms. There was no statistical difference in the number of patients having experienced at least one treatment emergent adverse
event related to the study treatment between placebo and Validive as summarized in the table below. Two patients in the placebo group and 2 patients in the Validive 50 µg
group  experienced  a  serious  treatment-emergent  adverse  event  (“STEAE”).  No  STEAEs  were  observed  in  the  Validive  100  µg  cohort.  No  patients  in  the  Validive-treated
cohorts were discontinued due to study drug. The 2-year survival rate was not statistically different between patients treated with placebo and Validive indicating that Validive
did not interfere with primary disease treatment.

All Serious Treatment-Emergent Adverse Events Related to Study Drug

MBT=mucoadhesive buccal tablet; n=number of patients studied

The mean overall patient compliance as assessed by the investigators was approximately 90%, and similar across all treatment groups. Overall compliance according to
patient diaries was also similar in all treatment groups and consistent with the compliance according to the investigator’s evaluation. The mean incidence of swallowing the MBT
was low (4.7%) for all patients based on 7,366 daily MBT applications across all treatment groups.

Our review of the Phase 2 clinical trial data suggests that the effect of Validive was much greater in OPC compared to non-OPC patients. We believe the Phase 2 data
along  with  the  mechanism  of  action  of  Validive  provide  a  rationale  for  developing  Validive  for  the  treatment  of  chemoradiation  induced  SOM  in  OPC  patients  as  a  first
indication. The most rapidly growing sub-population of HNC in the U.S. and Europe is OPC, largely driven by HPV+ disease. The oropharynx is the part of the throat at the
back of the mouth, which includes the soft palate, the base (rear one third) of the tongue, and the tonsils. HPV+ OPC is a molecularly defined population of HNC characterized
by the expression of a protein biomarker, p16 INK4a, and the presence of HPV DNA in the tumor. Evaluation of HPV status is part of the routine clinical assessment of patients
with OPC prior to initiating treatment.

Validive Phase 1 Clinical Trial Data

A Phase 1 clinical trial in 36 healthy volunteers comparing the pharmacokinetics of the systemic (oral tablet) clonidine HCl with clonidine MBT (local and sustained
delivery of clonidine to oral mucosa and oropharynx – Validive’s formulation) was completed. This was a single-center, Phase 1, single-blind randomized, three-period, three-
sequence, single-dose crossover study was conducted between August and November 2015. Healthy volunteers receiving Validive had far less systemic exposure to clonidine
with  the  50  µg  and  100  µg  clonidine  MBTs  (Validive)  versus  100  µg  clonidine  HCl  tablets  (swallowed  oral  tablet).  In  contrast,  levels  of  clonidine  in  saliva  in  volunteers
receiving a single dose of 50 µg and 100 µg clonidine MBT (Validive) was much greater than saliva levels in volunteers receiving a single dose of 100 µg clonidine HCl tablets.
Additionally, no significant effects on blood pressure were observed with the clonidine MBTs (Validive). Blood pressure effects were tested because clonidine is known to
lower blood pressure when absorbed systemically. These results are consistent with the expectation that the MBT formulation (Validive) is designed to release clonidine in the
oral cavity and oropharynx, as opposed to distributed systemically.

Both Validive 50 µg and 100 µg showed high salivary exposure (as seen above), with low systematic and blood pressure effect (as seen below):

Validive Preclinical Data

 The anti-inflammatory properties of clonidine were studied in a human oral mucosa organotypic culture model, as pro-inflammatory cytokines are believed to drive the
development  of  SOM.  Samples  of  healthy  non-keratinized  human  oral  mucosa  were  obtained  from  patients  undergoing  surgery.  The  experimental  oral  mucosa  pro-
inflammatory  process  was  mediated  by  the  addition  of  neuropeptide  substance  P  (“SP”)  to  the  culture  medium.  The  addition  of  SP  on  human  gingiva  induced  a  significant
increase in TNF-alpha, an important pro-inflammatory molecule involved in mucositis pathogenesis. Overall, on human gingiva stimulated by SP, a concentration dependent
decrease in TNF-alpha production was observed with clonidine, which was statistically significant at 3 µg/ml clonidine; see below:

Camsirubicin (5-imino-13-deoxydoxorubicin; formerly MNPR-201, GPX-150)

** = different from SP treatment alone, p<0.01

Our second product candidate, camsirubicin, is a novel analog of doxorubicin which has been designed to reduce the cardiotoxic side effects generated by doxorubicin
while retaining anti-cancer activity. A Phase 2 clinical trial for camsirubicin has been completed in patients with advanced (e.g., unresectable or metastatic) soft tissue sarcoma
(“ASTS”). Average life expectancy for these patients is 12-15 months. In this study, 52.6% of patients evaluable for tumor progression demonstrated clinical benefit (partial
response or stable disease), which was proportional to dose and consistently observed at higher cumulative doses of camsirubicin (>1000 mg/m2). Camsirubicin was very well
tolerated in this study and underscored the ability to potentially administer camsirubicin without restriction of cumulative dose in patients with ASTS. Although doxorubicin has
been the standard of care treatment for ASTS for over 40 years, doxorubicin is limited to a lifetime cumulative dose maximum of 450 mg/m 2. Even if a patient is responding to
doxorubicin, their treatment is discontinued once this lifetime cumulative dose has been reached.

Camsirubicin  is  a  proprietary  doxorubicin  analog  that  is  selective  for  topoisomerase  II-alpha.  Doxorubicin  is  used  to  treat  adult  and  pediatric  solid  and  blood
(hematologic) cancers, including soft tissue sarcomas, breast, gastric, ovarian and bladder cancers, leukemias and lymphomas. Despite clinical studies demonstrating the anti-
cancer  benefit  of  higher  cumulative  doses  of  doxorubicin,  the  clinical  efficacy  of  doxorubicin  has  historically  been  limited  by  the  risk  of  patients  developing  irreversible,
potentially  life-threatening  cardiotoxicity.  For  example,  several  clinical  studies  completed  in  the  1990s  demonstrated  that  concurrent  doxorubicin  (60  mg/m2,  8  cycles)  and
paclitaxel  gave  a  94%  overall  response  rate  in  patients  with  metastatic  breast  cancer  but  led  to  18%  of  these  patients  developing  congestive  heart  failure.  Reduction  of
doxorubicin  to  4-6  cycles  of  treatment  decreased  the  incidence  of  congestive  heart  failure,  but  also  reduced  response  rates  to  45-55%.  In  a  clinical  study  looking  at  dose
response, sarcoma patients on the high dose (75 mg/m2) doxorubicin had a response rate of 37% compared to just 18% in the low dose (45 mg/m2) doxorubicin group. With the
cumulative dose restriction on doxorubicin, the median progression free survival for ASTS patients is approximately 6 months, with median overall survival of 12-15 months.
There is a significant unmet opportunity to develop a replacement for doxorubicin that can be dosed higher and for longer to improve anti-tumor activity

Camsirubicin has been engineered specifically to retain the anticancer activity of doxorubicin while minimizing its toxic effects on the heart. Similar to doxorubicin, the
antitumor effects of camsirubicin are mediated through the stabilization of the topoisomerase II complex after a DNA strand break and DNA intercalation leading to tumor cell
apoptosis  (cell  death).  Inhibiting  the  topoisomerase  II-alpha  isoform  is  desired  for  the  anti-cancer  effect,  while  inhibiting  the  topoisomerase  II-beta  isoform  has  been
demonstrated to mediate, at least in part, the cardiotoxicity associated with all anthracycline drugs currently used in the clinic. Camsirubicin is substantially more selective than
doxorubicin  for  inhibiting  topoisomerase  II-alpha  versus  topoisomerase  II-beta.  This  selectivity  may  partly  explain  the  minimal  cardiotoxicity  that  has  been  observed  for
camsirubicin in preclinical and clinical studies to date. We believe that these attributes provide a strong rationale for developing camsirubicin as a monotherapy as well as in
combination with other anticancer agents, without potential restrictions on cumulative dose, and offer the opportunity to pursue a large market opportunity for camsirubicin in a
broad spectrum of cancer types.

Based on the encouraging clinical results to date, in September 2021, we commenced an open-label, Phase 1b dose escalation trial of camsirubicin plus growth factor
support (pegfilgrastim/G-CSF) in the U.S. as first-line treatment for patients with ASTS. The aim is to administer camsirubicin without restricting cumulative dose, thereby
potentially improving efficacy by keeping patients who are responding on treatment. These are patients who are not candidates for surgery or radiation treatment, and are largely
made  up  of  patients  with  metastatic  disease.  Doxorubicin  is  the  current  standard  of  care  in  the  first-line  setting  for  these  patients. Although  this  Phase  1b  is  designed  to
determine  the  maximum  tolerated  dose  of  camsirubicin,  given  the  historical  dose-dependent  anti-tumor  response  repeatedly  demonstrated  with  doxorubicin,  efficacy
measurements  are  being  tracked  in  these  patients  as  the  dose  is  increased.  In  November  2021,  the  first  dose  level  of  camsirubicin  had  been  completed,  with  a  positive
recommendation from the trial safety review committee to proceed to the next higher dose level. We are presently enrolling patients at the fifth dose level. The fifth dose level is
over twice the highest dose reached in any prior camsirubicin clinical trial (650 mg/m2 versus 265 mg/m2) and no drug-related cardiotoxicity has been observed to date up to the
current dose-level. The open-label Phase 1b camsirubicin dose-escalation trial is planning to enroll additional cohorts until the maximum tolerable dose is reached. In November
2022, we presented an abstract and poster of the Phase 1b clinical trial data at the Connective Tissue Oncology Society Annual Meeting in Vancouver, BC.

We currently anticipate topline results in the camsirubicin Phase 1b clinical trial by the end of 2023 and believe we have sufficient funds to advance the trial through
that  date.  However,  if  camsirubicin  reaches  higher  dose  levels  than  we  are  anticipating,  the  Phase  1b  clinical  trial  may  still  be  dosing  patients  beyond  the  end  of  2023  and
topline results may be deferred. Although we would likely consider this a positive development, it is possible that we would require additional funding to complete an extended
Phase  1b  clinical  trial  in  this  situation.  Regardless,  additional  funding  is  expected  to  be  required  to  support  further  development  through  and  beyond  our  ongoing  Phase  1b
clinical trial.

In June 2019, we entered into a clinical collaboration with Grupo Español de Investigación en Sarcomas (“GEIS”). GEIS is an internationally renowned non-profit
organization focused on the research, development and management of clinical trials for sarcoma, that has worked with many of the leading biotech and global pharmaceutical
companies. Following completion of our Phase 1b clinical trial, we continue to expect that GEIS will sponsor and lead a multi-country, randomized, open-label Phase 2 clinical
trial evaluating camsirubicin head-to-head against doxorubicin, the current first-line treatment for ASTS. The Phase 2 clinical trial is estimated to enroll 170 ASTS patients with
the primary endpoint of the trial being progression-free survival, with secondary endpoints including response rate, overall survival and incidence of treatment-emergent adverse
events. We will provide study drug to GEIS and supplemental financial support for the clinical trial. In addition to camsirubicin’s orphan drug designation in the U.S. by the
FDA, the European Commission also granted orphan drug designation for camsirubicin for the treatment of soft tissue sarcoma in the EU in November 2019.

Camsirubicin U.S. Market Opportunity

Camsirubicin is an analog of doxorubicin, the first anthracycline to gain FDA approval. Anthracyclines are a class of drugs that are among the most commonly used
agents in the treatment of cancer. They have demonstrated efficacy in a wide variety of cancers, including soft tissue sarcoma, breast cancer, lung cancer, ovarian cancer, and
lymphomas, among other types. Although doxorubicin was approved decades ago, it is still widely used. According to QY Research, in 2020 the global doxorubicin market was
$1.1836 billion, and expected to grow at a 7.7% compounded annual growth rate, with projections surpassing $1.8 billion by 2026. According to IQVIA, in 2015 the European
Union  had  over  $270  million  in  sales  between  doxorubicin  HCl  and  liposomal  doxorubicin.  Liposomal  versions  of  doxorubicin  (e.g.,  Doxil®)  demonstrated  that  a  different
formulation of doxorubicin with improved clinical benefits can command a significantly higher price premium compared to generic doxorubicin HCl.

The market opportunity for the first indication, ASTS, is anticipated to be substantial. In 2020, there were an estimated 13,130 new cases of soft tissue sarcoma (STS)
in the U.S., and approximately 5,350 deaths from STS, mainly from metastatic disease. Additionally, a few years ago a PDGFR-targeted antibody (olaratumab) was granted
accelerated approval based on data from an open label Phase 2 trial. In 2019, the olaratumab Phase 3 trial as first line for advanced soft tissue sarcoma came back negative,
resulting in the drug being pulled from the market. Olaratumab had just completed its second full year on the market in the U.S. and abroad before being pulled, reaching over
$304 million in sales in 2018, demonstrating the large unmet medical need and considerable market opportunity in ASTS.

Camsirubicin Clinical Data

Several clinical studies of camsirubicin have been completed.

In October 2013, a Phase 1 dose escalation study conducted at the University of Iowa completed enrollment of 24 patients who received one of eight different dose
levels of camsirubicin ranging from 14 to 265 mg/m2. No evidence of irreversible cardiotoxicity was observed in any of these patients, including 4 patients who received prior
anthracycline  (doxorubicin  or  related  molecules)  treatment.  Stable  disease  was  observed  in  55.0%  of  patients  in  this  Phase  1  study,  including  3  out  of  4  patients  with
leiomyosarcoma, which is a type of soft tissue sarcoma that originates in connective tissue and smooth muscle most commonly in the uterus, stomach and small intestine. No
growth factor support (G-CSF) was given to patients, and the limiting toxicity was neutropenia.

In January 2015, a multi-center open label single arm Phase 2 clinical trial was initiated in doxorubicin-naïve patients with ASTS. This Phase 2 clinical trial enrolled 22
patients and was completed in August 2016. Camsirubicin was administered intravenously at 265 mg/m 2 every 3 weeks for up to 16 doses, with all patients being given growth
factor support, and there was clear indication of anticancer activity at this well-tolerated dose and schedule. The majority of patients (52.6%) evaluable for tumor progression
demonstrated clinical benefit (stable disease or partial response), which was proportional to dose and consistently observed at higher cumulative doses of camsirubicin (>1000
mg/m2). The progression-free survival at 6 months was 38%, higher than the 6-month PFS of doxorubicin in three of the more recent studies, which showed 23%, 25%, and
33% 6-month PFS for doxorubicin. Camsirubicin was very well tolerated in this study and underscored the potential ability to administer camsirubicin without restriction for
cumulative  dose  in  patients  with ASTS.  Under  compassionate  use  access,  one  patient  received  20  cycles  of  camsirubicin  (cumulative  dose  5,300  mg/m 2). Apart  from  one
patient who developed febrile neutropenia and severe leukopenia, there were no grade 4 toxicities reported and no grade 3 side effects other than anemia. A transient decrease in
left ventricular ejection fraction (“LVEF”) was observed in four patients treated with camsirubicin. These decreases in LVEF in camsirubicin treated patients were not serious
adverse events and were transient, with LVEF subsequently returning to normal levels in all four subjects. Despite some subjects in this study receiving camsirubicin for up to
20 cycles, effects on cardiac function were of no clinical significance and there was no evidence of irreversible heart failure in any subject.

Camsirubicin Preclinical Data

In preclinical studies, camsirubicin showed a lack of acute as well as chronic functional cardiotoxicity and did not cause the cardiac histopathologic lesions observed
with doxorubicin in a chronic rabbit model. Below is in vitro data showing the lack of altered contractility with acute exposure of rabbit atria to camsirubicin, even at high
concentrations:

Camsirubicin Cardiac Contractility

Camsirubicin demonstrated limited effect on cardiac contractility, in-line with control

Chronic IV administration of camsirubicin two times per week into rabbits over the course of 13 weeks also showed a lack of cardiotoxicity of camsirubicin when
compared to doxorubicin (“DOX”). Echocardiography was performed weekly to obtain left ventricular fractional shortening (“LVFS”) measurements to assess cardiac function.
At  sacrifice,  all  six  doxorubicin-treated  rabbits  showed  cardiac  dysfunction  by  echocardiography,  and  LVFS  was  significantly  different  from  control  values  (p<0.001).  In
contrast, none of the camsirubicin-treated rabbits exhibited cardiac dysfunction by echocardiography at any time during the study. Below is a graph of the results:

Weekly Cardiac Echoes

None of the camsirubicin treated rabbits showed significant cardiac dysfunction compared to the vehicle control.

At  the  conclusion  of  the  13  weeks  of  drug  dosing,  the  rabbits  were  sacrificed,  and  the  left  atria  were  studied  to  assess  cardiac  function ex  vivo.  Atria  from  the
doxorubicin-treated rabbits had impaired cardiac contractility (dF/dt) compared to controls over the entire force-frequency range (1, 2 and 3 Hz). Cardiac contractility for the
camsirubicin treated cohort was not significantly different than the vehicle control. Below is a graph of the results:

Camsirubicin Cardiac Contractility

Cardiac  contractility  (dF/dt)  of  isolated  atria  at  the  three  contraction  rates  (1,  2,  and  3  contractions/sec)  obtained  from  rabbits  chronically  infused  with  either
doxorubicin, camsirubicin or saline vehicle (control).

Values are mean, error bars are standard error of the mean (SEM). Camsirubicin demonstrated limited effect on cardiac contractility, in-line with placebo.

Finally,  cardiac  scoring  of  the  left  ventricle  walls  obtained  from  the  rabbits  in  this  study  by  a  histopathologist  showed  increased  microscopic  injury  in  hearts  from
doxorubicin-treated  rabbits  compared  to  hearts  from  rabbits  administered  the  vehicle  control.  Heart  tissues  from  camsirubicin-treated  rabbits  were  the  same  as  the  vehicle
controls.

MNPR-101 for Radiopharmaceutical Use

Our  third  program  is  based  on  MNPR-101  (formerly  huATN-658),  a  novel  first-in-class  humanized  monoclonal  antibody  to  the  urokinase  plasminogen  activator
receptor (“uPAR”), for its use as a radiopharmaceutical in advanced cancers. uPAR is highly expressed in tumors while healthy tissue rarely, if ever, expresses uPAR. The
expression of uPAR on diseased cells and tissues allows for selective targeting of MNPR-101, which may be modified to carry imaging and therapeutic payloads.

MNPR-101 represents a novel approach for drug targeting of uPAR as it does not interfere with normal binding of uPA to uPAR. It instead blocks the CD11b (alpha-

M)-uPAR interaction. MNPR-101 is on its own believed to have potential activity against many different cancer types because it:

●

●

●

●

●

is selectively expressed on metastatic tumor, tumor-associated immune, and angiogenic endothelial cells, but not on most normal cells. Several Phase 1 positron
emission tomography (“PET”) imaging studies in human advanced cancer patients show that uPAR can only be detected in the tumor and not in normal tissues;

is central to several extracellular and intracellular oncogenic pathways required for metastasis (inhibiting the uPA system in turn inhibits many other downstream
targets, such as MAPK, AKT, MEK, and FAK, that are currently being targeted by other companies);

is expressed on immune cells that allow the tumor to evade recognition by the immune system;

mediates antibody-dependent cellular cytotoxicity (ADCC); and

has the potential to interfere at several different signaling pathways that converge at uPAR.

Table of Contents

Based upon the anticipated non-overlapping toxicity and distinct mechanism of action, we believe MNPR-101 has the potential to be used in combination with existing
cancer therapies. The selective expression of uPAR in tumors underpins our expectation that MNPR-101 will be well-tolerated and amenable to a radiopharmaceutical treatment
approach.

MNPR-101-Zr as a Potential Imaging Agent

MNPR-101-Zr  is  being  developed  as  an  imaging  agent  for  the  diagnosis  and  surveillance  of  multiple  cancer  types.  In  February  2023,  we  announced  that  based  on
promising recently generated preclinical imaging results with MNPR-101-Zr showing high uptake across multiple cancer types, we and NorthStar were committing to additional
funding with the aim of initiating a first-in-human imaging study with MNPR-101-Zr as early as the end of this year.

MNPR-101-Zr  is  a  zirconium-89  labeled  version  of  MNPR-101.  Positron  emission  tomography  (“PET”)  imaging  of  preclinical  mouse  models  for  triple-negative

breast, colorectal, and pancreatic tumors displayed high and selective uptake of MNPR-101-Zr in these uPAR-expressing tumors.

These proof-of-concept studies provide support for a first-in-human PET imaging study with MNPR-101-Zr and a future therapeutic study using actinium-225 labeled
radioimmunotherapeutic version of MNPR-101. Overall, the imaging results demonstrate the potential utility of MNPR-101 as a precision targeting agent for both imaging and
therapy in multiple cancer indications.

MNPR-101 RIT

Also  pursuant  to  our  collaboration  with  NorthStar,  we  continue  to  develop  potential  radioimmunotherapeutics  (“RITs”)  based  on  MNPR-101.  Our  collaboration
combines NorthStar’s expertise in the innovative production, supply, and distribution of important medical radioisotopes with our expertise in therapeutic drug development.
NorthStar and we have filed provisional composition of matter patents covering the actinium-based radiopharmaceutical drug candidate (MNPR-101-PCTA-Ac-225). We are
currently evaluating pathways to initiating a first-in-human study with this  drug candidate.

MNPR-202 and Related Analogs

In  June  2021,  we  entered  into  a  collaboration  agreement  with  the  Cancer  Science  Institute  of  Singapore  (“CSI  Singapore”),  one  of Asia’s  premier  cancer  research
centers, at the National University of Singapore (“NUS”) (consistently ranked as one of the world’s top universities) to evaluate the activity of MNPR-202 and related analogs
in multiple types of cancer. MNPR-202 was designed to retain the same potentially non-cardiotoxic backbone as camsirubicin but is modified at other positions which may
enable it to work in certain cancers that are resistant to camsirubicin and doxorubicin. In December 2020, we announced the issuance of our composition of matter U.S. patent
(US10,450,340) covering MNPR-202 and related analogs. CSI Singapore has tested MNPR-202 in preclinical cancer models with promising results and is currently conducting
additional preclinical studies with MNPR-202. In December 2022, in collaboration with Dr. Anand Jeyasekharan of CSI Singapore, we presented an abstract and poster of the
preclinical data of MNPR-202 at the American Society of Hematology 64th Annual Meeting in New Orleans, LA.

License, Development and Collaboration Agreements

Onxeo S.A.

In June 2016, we executed an agreement with Onxeo S.A., a French public company, which gave us the exclusive option to license (on a world-wide exclusive basis)
Validive (clonidine hydrocholoride mucobuccal tablet; clonidine HCI MBT) a mucoadhesive tablet of clonidine based on the Lauriad mucoadhesive technology. The agreement
includes clinical, regulatory, developmental and sales milestones that could reach up to $108 million if we achieve all milestones, and escalating royalties from 5% to 10% on
net sales. In September 2017, we exercised the option to license Validive from Onxeo for $1 million, but as of March 10, 2023, we have not been required to pay Onxeo any
other funds under the agreement. We will need to raise significant funds or enter into a collaboration partnership to support the completion of clinical development and potential
marketing approval of Validive.

18

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Under  the  agreement,  we  are  required  to  pay  royalties  to  Onxeo  on  a  product-by-product  and  country-by-country  basis  until  the  later  of  (1)  the  date  when  a  given
product is no longer within the scope of a patent claim in the country of sale or manufacture, (2) the expiry of any extended exclusivity period in the relevant country (such as
orphan  drug  exclusivity,  pediatric  exclusivity,  new  chemical  entity  exclusivity,  or  other  exclusivity  granted  beyond  the  expiry  of  the  relevant  patent),  or  (3)  a  specific  time
period after the first commercial sale of the product in such country. In most countries, including the U.S., the patent term is generally 20 years from the earliest claimed filing
date of a non-provisional patent application in the applicable country, not taking into consideration any potential patent term adjustment that may be filed in the future or any
regulatory extensions that may be obtained. The royalty termination provision pursuant to (3) described above is shorter than 20 years and is the least likely cause of termination
of royalty payments.

The Onxeo license agreement does not have a pre-determined term, but expires on a product-by-product and country-by-country basis; that is, the agreement expires
with respect to a given product in a given country whenever our royalty payment obligations with respect to such product have expired. The agreement may also be terminated
early for cause if either we or Onxeo materially breach the agreement, or if either we or Onxeo become insolvent. We may also choose to terminate the agreement, either in its
entirety or as to a certain product and a certain country, by providing Onxeo with advance notice.

Grupo Español de Investigación en Sarcomas (“GEIS”)

In June 2019, we executed a clinical collaboration with GEIS for the development of camsirubicin in patients with ASTS. Following completion of the Phase 1b clinical
trial in the U.S. that we initiated in the third quarter of 2021 with the first patient dosed in October 2021, we continue to expect that GEIS will sponsor and lead a multi-country,
randomized, open-label Phase 2 clinical trial to evaluate camsirubicin head-to-head against doxorubicin, the current first-line treatment for ASTS. We will provide study drug
and supplemental financial support for the clinical trial. =For the three months ended March 31, 2021, we incurred $0.3 million in expenses related to the GEIS collaboration
including  clinical  material  manufacturing-related  expense,  clinical  consulting,  database  management  expenses  and  intellectual  property  expenses.    We  can  terminate  the
agreement by providing GEIS with advance notice, and without affecting our rights and ownership to any related intellectual property or clinical data. In the second quarter of
2021, due to regulatory delays in Spain, we decided to conduct an open-label Phase 1b clinical trial of camsirubicin in the U.S., therefore no expenses were incurred related to
the GEIS collaboration beyond March 31, 2021.

XOMA Ltd.

To humanize our MNPR-101 antibody, we have taken a non-exclusive license to XOMA (US) LLC’s humanization technology and know-how. Humanization involves
replacing most of the non-critical parts of the mouse sequence of an antibody with the human sequence to minimize the ability of the human immune system to recognize this
antibody as foreign. As such, MNPR-101 has been engineered to be 95% human sequence using the XOMA technology. Under the terms of the license, we are to pay only upon
developmental and sales milestone achievements which could reach up to $14.925 million if we achieve all milestones. The agreement does not require the payment of sales
royalties. There can be no assurance that we will reach any milestones. As of March 10, 2023, we had not reached any milestones and had not been required to pay XOMA Ltd.
any funds under this license agreement. The first milestone payment is payable upon first dosing of a human patient in a Phase 2 clinical trial.

Intellectual Property Portfolio and Exclusivity

An important part of our strategy is obtaining patent protection to help preserve the proprietary nature of our product candidates, and to prevent others from developing
competitive agents that are similar. Our patent portfolio includes issued patents and pending patent applications in the U.S. and in foreign countries. Our general practice is to
seek patent protection in major markets worldwide.

Validive

We  license  all  intellectual  property  related  to  Validive  from  Onxeo  S.A.,  a  French  public  company.  See  “Business  –  License,  Development  and  Collaboration
Agreements”. Validive is covered by 57 issued patents in 31 jurisdictions, including the U.S., EU, Japan, and other Asian countries, and has orphan drug designation in the EU
as well as Fast Track designation from the FDA. These patents are method of use patents that cover the use of Validive to prevent and/or treat inflammation and inflammatory
pain  of  the  mucosa  including  cancer  therapy-induced  mucositis;  the  use  of  clonidine  or  clonidine  derivatives  for  the  prevention  or  treatment  of  adverse  side  effects  of
chemotherapy; and clonidine and/or clonidine derivatives for use in the prevention of skin injury resulting from radiotherapy, and have been assigned to us pursuant to our
license agreement with Onxeo. The latest patent expires in 2035 not accounting for possible extensions.

19

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In  November  2020,  we  announced  a  series  of  recently  issued  patents  for  Validive  (clonidine  HCl  mucobuccal  tablet).  These  patents,  including  U.S.  Patent  No.
10,675,271, provide claims covering “Clonidine and/or clonidine derivatives for use in the prevention and/or treatment of adverse side effects of chemotherapy”. These patents
expand  the  potential  use  of  Validive  in  cancer  patients,  beyond  the  earlier  allowed  claims  for  the  prevention  of  oral  mucositis  in  patients  receiving  CRT.  Specifically,  they
provide  protection  for  the  potential  ability  of  Validive  to  prevent  or  treat  common  chemotherapy-associated  side  effects  such  as  asthenia  and  fatigue  and  would  provide
protection should we determine in the future to conduct additional Validive development activities related to adverse side effects of chemotherapy beyond oropharyngeal cancer.

Camsirubicin

Camsirubicin (GPX-150) is covered by manufacturing process patents. We have a patent for chemical synthesis technology that efficiently converts cardiotoxic “13-
keto” anthracyclines such as doxorubicin, daunorubicin, epirubicin, and idarubicin into novel, patentable, and most likely less-cardiotoxic “5-imino-13-deoxy” analogs. A novel
chemical  composition  of  an  intermediate  for  this  synthesis  is  also  patented.  In  addition,  we  have  a  patent  covering  the  combination  of  camsirubicin  with  paclitaxel  for  the
treatment of cancer, plus covering the method of use of these two drugs for this purpose. Our camsirubicin patent portfolio contains eight issued U.S. patents (two of which have
expired) and one U.S. pending patent application. We have certain corresponding patents and applications in twenty-nine foreign jurisdictions, including the U.S., EU, Japan,
and other Asian countries. The process patents for the synthesis of camsirubicin intermediates will expire in 2024 and the patents covering the combination use of camsirubicin
and  its  analogs  with  taxanes  will  expire  in  2026.  The  patent  covering  novel,  potentially  more  potent  analogs  of  camsirubicin  expires  in  2038.  We  may  pursue  patent  term
extensions  where  appropriate.  We  have  obtained  patent  protection  around  the  intermediates  and  process  used  to  manufacture  camsirubicin  and  we  expect  to  obtain  Hatch-
Waxman exclusivity (applicable to new chemical entities) for 5 years that will prevent generic competition. We have also obtained U.S. and EU orphan drug status in soft tissue
sarcoma with additional orphan cancer indications expected to follow.

In  December  2020,  we  announced  the  issuance  of  a  U.S.  patent  (US  10,450,340)  covering  compositions  of  matter  (2-pyrrilino  camsirubicin)  for  a  novel  family  of
camsirubicin  analogs.  This  patent,  which  expands  the  Company’s  camsirubicin  intellectual  property  portfolio,  is  expected  to  expire  in  2038  not  including  any  patent  term
extensions. The patent broadens our camsirubicin portfolio and creates a pipeline that has been designed to retain the potentially favorable non-cardiotoxic chemical backbone
of camsirubicin and the potent broad-spectrum antitumor activity of doxorubicin. Further, preclinical evidence suggests that this new family of 2-pyrrilino camsirubicin analogs
could be active in doxorubicin-resistant tumor cells which may enable use in cancer types beyond those possible with camsirubicin.

MNPR-101

Our  patent  portfolio  for  our  MNPR-101  antibody  (huATN-658),  as  well  as  its  epitope,  consists  of  two  issued  U.S.  composition  of  matter  and  their  methods  of  use
patents  and  corresponding  (granted  and  pending)  patents  and  patent  applications  in  twenty-two  foreign  jurisdictions,  including  the  European  Union,  Japan,  and  other Asian
countries. These patents are owned by us. The patents covering the composition of matter of MNPR-101 will expire in 2025 and the patents covering the MNPR-101 epitope
will expire in 2027. Being a novel biologic, it is eligible for 12 years of exclusivity in the U.S. under the Biologics Price Competition and Innovation Act (“BPCI Act”), and it
will  benefit  from  varying  durations  of  similar  exclusivity  in  numerous  other  countries.  The  Radio-Immuno-Therapeutic  derivative  of  MNPR-101  (uPRIT)  patent,  if  granted
expires in 2041.

Patent life determination depends on the date of filing of the application and other factors as promulgated under the patent laws. In most countries, including the U.S.,
the patent term is generally 20 years from the earliest claimed filing date (the priority date) of a non-provisional patent application in the applicable country, not taking into
consideration any potential patent term adjustment that may be filed in the future or any regulatory extensions that may be obtained. Some of our patents are currently near
expiration and we may pursue patent term extensions for these where appropriate. See “Risk Factors – Risks Related to our Intellectual Property”.

MNPR-101 for Radiopharmaceutical Use

In  collaboration  with  NorthStar,  we  filed  a  provisional  patent  application  entitled  “Precision  Radioimmunotherapeutic  Targeting  of  the  Urokinase  Plasminogen
Activator Receptor (uPAR) for Treatment of Severe COVID-19 Disease” with the USPTO on June 15, 2020. A full international application (International Application Number
PCT/US2021/037416) that claims priority to the provisional filing date was filed under the Patent Cooperation Treaty (“PCT”) on June 15, 2021. This application covers novel
compositions and uses of cytotoxic radioisotopes attached to antibodies that bind to uPAR, thereby creating precision targeted radiotherapeutics, also known as uPRITs, for the
treatment of severe COVID-19 and other respiratory diseases. Advanced COVID-19 patients frequently develop severe, life-threatening, pulmonary inflammation as a result of
a viral induced cytokine storm. The development of this cytokine storm is associated with a high rate of mortality in severe COVID-19 patients, even when oxygen support and
mechanical ventilation are utilized. uPRITs have been designed with the goal of selectively eradicating the aberrantly activated immune cells responsible for causing cytokine
storm and its harmful systemic effects. The co-inventors of the provisional patent application are James Harvey, Chief Scientific Officer of NorthStar, and Andrew P. Mazar,
former Monopar Chief Scientific Officer.

In May 2021, we and NorthStar filed a provisional patent application with the USPTO titled “Bio-Targeted Radiopharmaceutical Compositions Containing Ac-225 and
Methods of Preparation.” Radiopharmaceutical therapy is a promising approach to treat cancer and other diseases using radioactive isotopes bound with proteins/antibodies to
target  and  kill  cells.  If  validated  through  further  evaluation,  it  could  potentially  improve  efficacy  and  safety  and  enhance  manufacturing  efficiency  of  actinium-based
radiopharmaceuticals, the full potential of which are presently constrained by the price and scarcity of Ac-225.

Also  in  May  2021,  we  and  NorthStar  filed  a  provisional  composition  of  matter  patent  application  titled  “Urokinase  Plasminogen  Activator  Receptor-Targeted
Radiopharmaceutical”  covering  a  radiotherapeutic  consisting  of  our  proprietary  antibody  MNPR-101  bound  to  Ac-225  via  the  isotope  binding  agent  PCTA.  This  RIT
demonstrated 98% radiochemical purity and high stability and has the potential to be a highly selective, potent treatment for a variety of cancers, severe COVID-19, and other
diseases characterized by aberrant uPA receptor expression.

Manufacturing

We do not currently own or operate manufacturing facilities for the production or testing of Validive, camsirubicin, MNPR-101, MNPR-101-Zr, MPNR-101 RITs or
MNPR-202, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We presently depend on third-party contract manufacturers for all our
required raw materials, Active Pharmaceutical Ingredients (“API”), and finished drug products for our preclinical and clinical studies. Both COVID-19 and the Russia-Ukraine
war, and related impacts on inflation and supply chain logistics, may impact the cost and delay shipping of supplies for our clinical materials manufacturing due to the rising
cost of fuel and sanctions that may delay global shipping. We have completed manufacturing of the clinical batches of drug product for Validive that are currently being utilized
in our ongoing Phase 2b/3 VOICE clinical trial and for camsirubicin which are being used in our ongoing Phase 1b dose-escalation camsirubicin clinical trial. We are in the
midst of manufacturing more camsirubicin for the clinical trials. We continue to develop MNPR-101-Zr, MNPR-101 RIT and MNPR-202 for potential scale-up.

Sales and Marketing

In  light  of  our  stage  of  corporate  development,  we  have  not  yet  established  a  commercial  organization  or  distribution  capabilities.  We  have  retained  worldwide
commercial rights for our product candidates. If our product candidates receive marketing approval, we plan to commercialize them in the U.S. and potentially in Europe with
our own focused, specialty sales force to be developed. We would expect to conduct most of the buildout of this organization following approval in the U.S. or following similar
marketing authorizations in Europe of any of our product candidates. We expect to explore commercialization of Validive and potentially other product candidates in certain
markets outside the U.S., including the EU, utilizing a variety of collaboration, distribution and other sales and marketing arrangements with one or more third parties.

Oncology Market Competition

The  pharmaceutical  industry  in  general,  and  the  oncology  therapeutics  sector  in  particular,  are  characterized  by  intense  competition.  We  face  competition  from
pharmaceutical and biotechnology companies, many of which are larger and better financed than us. We also face competition in our efforts to develop and commercialize new
oncology therapeutics from academic and government laboratories. The therapeutics that we are developing, if successfully commercialized, will have to compete with existing
therapeutics  already  on  the  market  and  novel  therapeutics  currently  in  development,  as  well  as  new  therapeutics  that  may  be  discovered  and  developed  in  the  future.  Our
product candidates will also have to compete with alternate treatment modalities, such as improvements in radiation treatments, which are also subject to continual innovation
and improvement. Additional information can be found in the section entitled “Risk Factors – Risks Related to Our Business Operations and Industry.”

Validive

There is no effective standard of care or FDA approved preventive or therapeutic treatment for patients that develop chemoradiation-induced SOM. Only symptomatic
treatments  such  as  opioids  and  palliative  mouthwashes  are  available  but  have  no  effect  on  the  occurrence,  time  to  onset,  or  duration  of  SOM.  Our  primary  competitor  is  a
dismutase mimetic which recently completed its Phase 3 clinical development including submission to the FDA for marketing approval. The dismutase mimetic is administered
through a daily 60-minute intravenous (“IV”) infusion to be completed within an hour before each radiation treatment. Validive, in comparison, is an easy to use, once daily
self-administered oral/buccal tablet that acts locally at the sites of SOM.

Camsirubicin

We believe our camsirubicin program, if approved, could replace doxorubicin as the first-line treatment for ASTS. In addition, we believe that camsirubicin would
compete  with  a  number  of  currently  available  anthracycline-based  drugs  on  the  market  for  other  cancer  indications.  These  are  largely  derivatives  of  doxorubicin,  or
reformulations of doxorubicin such as liposomal doxorubicin (e.g., Doxil, sold by Johnson & Johnson). All of these have the issue of cardiotoxicity. In addition to approved
products, there are a number of product candidates in development, largely as new formulations or derivatives of doxorubicin.

MNPR-101 for Radiopharmaceutical Use and MNPR-202

Our MNPR-101-Zr, MNPR-101 RIT and MNPR-202 programs are in the early stages of development and the most susceptible to all of the competitive factors listed in

the first paragraph of this section on Oncology Market Competition.

Government Regulation and Product Approval

Government authorities in the U.S., at the federal, state and local level, and in other countries extensively regulate, among other things, the research, development,
testing,  manufacture,  quality  control,  approval,  labeling,  packaging,  storage,  record-keeping,  promotion,  advertising,  distribution,  post-approval  monitoring  and  reporting,
marketing and export and import of products such as those we are developing. The pharmaceutical product candidates that we develop must be approved by the FDA before
they may be legally marketed in the U.S. See “Risk Factors – Risks Related to Clinical Development and Regulatory Approval”.

U.S. Pharmaceutical Product Development Process

In  the  U.S.,  the  FDA  regulates  pharmaceutical  products  under  the  Federal  Food,  Drug  and  Cosmetic Act  (“FDCA”)  and  implementing  regulations.  Pharmaceutical
products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate
federal,  state,  local  and  foreign  statutes  and  regulations  require  the  expenditure  of  substantial  time  and  financial  resources.  Failure  to  comply  with  the  applicable  U.S.
requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial enforcement. FDA
enforcement could result in refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial
suspension  of  production  or  distribution  injunctions,  fines,  refusals  of  government  contracts,  restitution,  disgorgement  or  civil  or  criminal  penalties. Any  agency  or  judicial
enforcement action could have a material adverse effect on us. The process required by the FDA before a non-biological pharmaceutical product may be marketed in the U.S.
generally involves the following:

Completion  of  preclinical  laboratory  tests,  animal  studies  and  formulation  studies  according  to  Good  Laboratory  Practices  (“GLP”),  and  other  applicable
regulations;

Submission to the FDA of an Investigational New Drug application (“IND”), which must become effective before human clinical studies may begin;

Performance  of  adequate  and  well-controlled  human  clinical  studies  according  to  the  FDA’s  current  Good  Clinical  Practices  (“GCP”),  to  establish  the  safety,
efficacy and optimum dose of the proposed pharmaceutical product for its intended use;

Submission to the FDA of a New Drug Application (“NDA”) or Biologics License Application (“BLA”), for a new pharmaceutical product;

Satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the pharmaceutical product is produced to assess compliance with
the  FDA’s  current  Good  Manufacturing  Practice  standards  (“cGMP:”),  to  assure  that  the  facilities,  methods  and  controls  are  adequate  to  preserve  the
pharmaceutical product’s identity, strength, quality and purity;

FDA audits of the preclinical and clinical study sites that generated the data in support of the NDA or BLA;

FDA review and approval of the NDA; and

Fulfillment of FDA post-marketing requirements, if any.

The  lengthy  process  of  seeking  required  approvals  and  the  continuing  need  for  compliance  with  applicable  statutes  and  regulations  require  the  expenditure  of

substantial resources, and approvals are inherently uncertain.

Before testing any compounds with potential therapeutic value in humans, the pharmaceutical product candidate enters the preclinical testing stage. Preclinical tests
include  laboratory  evaluations  of  product  chemistry,  toxicity  and  formulation,  as  well  as  in-vitro  and  animal  studies  to  assess  the  potential  safety  and  activity  of  the
pharmaceutical product candidate. These early proof-of-principle studies are done using sound scientific procedures and thorough documentation. The conduct of single and
repeat dose toxicology and toxicokinetic studies in animals must comply with federal regulations and requirements including GLP. The sponsor must submit the results of the
preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the
IND. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA has concerns and notifies the sponsor. In such a case, the IND sponsor and the
FDA must resolve any outstanding concerns before the clinical study can begin. If resolution cannot be reached within the 30-day review period, either the FDA places the IND
on clinical hold, or the sponsor withdraws the application. The FDA may also impose clinical holds on a pharmaceutical product candidate at any time before or during clinical
studies due to safety concerns or non-compliance. Accordingly, it is not certain that submission of an IND will result in the FDA allowing clinical studies to begin, or that, once
begun, issues will not arise that suspend or terminate such clinical studies.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at
the end of Phase 2, and before an NDA or BLA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share
information about the data gathered to date, for the sponsor to ask specific questions to the FDA, for the FDA to provide advice, and for the sponsor and FDA to reach agreement
on the next phase of development. Sponsors typically use the end of Phase 2 meeting to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3
clinical (registration) trial(s) that they believe will support approval of the new drug. A sponsor may be able to request a Special Protocol Assessment (“SPA”), the purpose of
which is to reach agreement with the FDA on the Phase 3 clinical trial protocol design and analyses that will form the primary basis of an efficacy claim.

According to FDA guidance for industry on the SPA process, a sponsor which meets the prerequisites may make a specific request for a SPA and provide information
regarding the design and size of the proposed clinical trial. The FDA’s goal is to evaluate the protocol within 45 days of the request to assess whether the proposed trial is
adequate, and that evaluation may result in discussions and a request for additional information. A SPA request must be made before the proposed trial begins, and all open
issues must be resolved before the trial begins. If a written agreement is reached, it will be documented and made part of the IND record. The agreement will be binding on the
FDA and may not be changed by the sponsor or the FDA after the trial begins except with the written agreement of the sponsor and the FDA or if the FDA determines that a
substantial scientific issue essential to determining the safety or efficacy of the drug was identified after the testing began.

Clinical studies involve the administration of the pharmaceutical product candidate to healthy volunteers or patients under the supervision of qualified investigators,
generally physicians not employed by or under the clinical study sponsor’s control. Clinical studies are conducted under protocols detailing, among other things, the objectives
of the clinical study, dosing procedures, subject selection and exclusion criteria, how the results will be analyzed and presented and the parameters to be used to monitor subject
safety. Each protocol must be submitted to the FDA as part of the IND. Clinical studies must be conducted in accordance with Good Clinical Practice (“GCP”) guidelines.
Further, each clinical study must be reviewed and approved by an independent institutional review board (“IRB”), at, or servicing, each institution at which the clinical study
will be conducted. An IRB is charged with protecting the welfare and rights of study participants and is tasked with considering such items as whether the risks to individuals
participating in the clinical studies are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided
to each clinical study subject or his or her legal representative and must monitor the clinical study until completed.

Human clinical studies are typically conducted in three sequential phases that may overlap or be combined:

●

●

●

●

●

Phase  1.  The  pharmaceutical  product  is  initially  introduced  into  healthy  human  subjects  and  tested  for  safety,  dosage  tolerance,  absorption,  metabolism,
distribution and excretion.

Phase 2. The pharmaceutical product is evaluated in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the
efficacy of the product for specific targeted diseases, to determine dosage tolerance, optimal dosage and dosing schedule and to identify patient populations with
specific characteristics where the pharmaceutical product may be more effective.

Phase  3.  Clinical  studies  are  undertaken  to  further  evaluate  dosage,  clinical  efficacy  and  safety  in  an  expanded  patient  population  at  geographically  dispersed
clinical study sites. These clinical studies are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labeling.
The studies must be well-controlled and usually include a control arm for comparison. One or two Phase 3 studies are required by the FDA for an NDA or BLA
approval, depending on the disease severity and other available treatment options.

Post-approval studies, or Phase 4 clinical studies, may be conducted after initial marketing approval. These studies are used to gain additional experience from the
treatment of patients in the intended therapeutic indication.

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and written IND safety reports must be submitted to the
FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk for human
subjects. Phase 1, Phase 2 and Phase 3 clinical studies may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data
safety monitoring board may suspend a clinical study 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 study at its institution if the clinical study is not being conducted
in accordance with the IRB’s requirements or if the pharmaceutical product has been associated with unexpected serious harm to patients.

Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical
characteristics of the pharmaceutical product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The
manufacturing process must be capable of consistently producing quality batches of the pharmaceutical product candidate and, among other things, must develop methods for
testing the identity, strength, quality and purity of the final pharmaceutical product. Additionally, appropriate packaging must be selected and tested, and stability studies must
be conducted to demonstrate that the pharmaceutical product candidate does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

The  results  of  product  development,  preclinical  studies  and  clinical  studies,  along  with  descriptions  of  the  manufacturing  process,  analytical  tests  conducted  on  the
chemistry of the pharmaceutical product, proposed labeling and other relevant information are submitted to the FDA as part of an NDA or BLA requesting approval to market
the product. The submission of an NDA or BLA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain limited circumstances.

In addition, under the Pediatric Research Equity Act (“PREA”), an NDA, BLA or a supplement thereof must contain data to assess the safety and effectiveness of the
pharmaceutical 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. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply
to any pharmaceutical product for an indication for which orphan designation has been granted.

The FDA reviews all NDAs and BLAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA or BLA for
filing.  Once  the  submission  is  accepted  for  filing,  the  FDA  begins  an  in-depth  review  of  the  NDA  or  BLA.  Under  the  goals  and  policies  agreed  to  by  the  FDA  under  the
Prescription Drug User Fee Act (“PDUFA”), the FDA has 10 months in which to complete its initial review of a standard NDA or BLA and respond to the applicant, and six
months for a priority NDA or BLA. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs or BLAs. The review process and the PDUFA goal
date may be  extended  by  three  months  if  the  FDA  requests  or  if  the  NDA  or  BLA  sponsor  otherwise  provides  additional  information  or  clarification  regarding  information
already provided in the submission within the last three months before the PDUFA goal date.

After  the  NDA  or  BLA  submission  is  accepted  for  filing,  the  FDA  reviews  the  NDA  or  BLA  application  to  determine,  among  other  things,  whether  the  proposed
product  is  safe  and  effective  for  its  intended  use,  and  whether  the  product  is  being  manufactured  in  accordance  with  cGMP  to  assure  and  preserve  the  product’s  identity,
strength,  quality  and  purity.  The  FDA  may  refer  applications  for  novel  pharmaceutical  products  or  pharmaceutical  products  which  present  difficult  questions  of  safety  or
efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should
be  approved  and  under  what  conditions.  The  FDA  is  not  bound  by  the  recommendations  of  an  advisory  committee,  but  it  considers  such  recommendations  carefully  when
making decisions. During the pharmaceutical product approval process, the FDA also will determine whether a risk evaluation and mitigation strategy (“REMS”), is necessary
to assure the safe use of the pharmaceutical product. If the FDA concludes that a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS; the FDA
will not approve the NDA or BLA without a REMS, if required.

Before approving an NDA or BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines
that  the  manufacturing  processes  and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product  within  required
specifications. Additionally, before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites as well as the site where the pharmaceutical product is
manufactured to assure compliance with GCP and cGMP. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable, it will
outline the deficiencies in the submission and often will request additional testing or information. In addition, the FDA will require the review and approval of product labeling.

The NDA and BLA review and approval process is lengthy and difficult and the FDA may refuse to approve an NDA or BLA if the applicable regulatory criteria are
not satisfied or may require additional clinical data or other data and information. Even if such data and information are submitted, the FDA may ultimately decide that the
NDA  or  BLA  does  not  satisfy  the  criteria  for  approval.  Data  obtained  from  clinical  studies  are  not  always  conclusive  and  the  FDA  may  interpret  data  differently  than  the
sponsor interprets the same data. The FDA will issue a complete response letter if the agency decides not to approve the NDA or BLA. The complete response letter usually
describes all of the specific deficiencies in the NDA or BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major,
for  example,  requiring  additional  clinical  studies. Additionally,  the  complete  response  letter  may  include  recommended  actions  that  the  applicant  might  take  to  place  the
application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in
the letter, or withdraw the application.

Table of Contents

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited,
which  could  restrict  the  commercial  value  of  the  product.  Further,  the  FDA  may  require  that  certain  contraindications,  warnings  or  precautions  be  included  in  the  product
labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to further assess pharmaceutical product safety and effectiveness and may
require testing and surveillance programs to monitor the safety of approved products that have been commercialized.

Expedited Development and Review Programs

The FDA has a Fast Track program that is intended to expedite or facilitate the process for reviewing new pharmaceutical products that meet certain criteria. Validive
has  Fast  Track  designation.  New  pharmaceutical  products  are  eligible  for  Fast  Track  designation  if  they  are  intended  to  treat  a  serious  or  life-threatening  condition  and
demonstrate the potential to address unmet medical needs for the condition. The Fast Track designation must be requested by the sponsor. Fast Track designation applies to the
combination of the product and the specific indication for which it is being studied. With a Fast Track designated product, the FDA may consider for review sections of the
NDA or BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA or BLA, if the
FDA agrees to accept sections of the NDA or BLA and determines that the schedule is acceptable and if the sponsor pays any required user fees upon submission of the first
section of the NDA or BLA.

Any product submitted to the FDA for marketing approval, including a Fast Track program, may also be eligible for other types of FDA programs intended to expedite
development and review, such as priority review and accelerated approval. Any product is eligible for priority review if it has the potential to provide safe and effective therapy
where no satisfactory alternative therapy exists or a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. The FDA
will attempt to direct additional resources to the evaluation of an application for a new pharmaceutical product designated for priority review in an effort to facilitate the review.
Additionally,  a  product  may  be  eligible  for  accelerated  approval.  Pharmaceutical  products  studied  for  their  safety  and  effectiveness  in  treating  serious  or  life-threatening
illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval, which means that the products may be approved on the
basis of adequate and well-controlled clinical studies establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or
on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity. As a condition of approval, the FDA may require that a sponsor of a pharmaceutical
product  receiving  accelerated  approval  perform  adequate  and  well-controlled  post-marketing  clinical  studies.  In  addition,  the  FDA  currently  requires  as  a  condition  for
accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Fast Track designation, priority
review and accelerated approval do not change the standards for approval but may expedite the development or approval process.

Breakthrough Therapy Designation

The FDA is also required to expedite the development and review of the application for approval of drugs that are intended to treat a serious or life-threatening disease
or condition where preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant
endpoints. Under the breakthrough therapy program, the sponsor of a new product candidate may request that the FDA designate the product candidate for a specific indication
as a breakthrough therapy concurrent with, or after, the filing of the IND for the product candidate. The FDA must determine if the product candidate qualifies for breakthrough
therapy designation within 60 days of receipt of the sponsor’s request. Validive, camsirubicin and MNPR-101 may all be eligible for breakthrough therapy designation pending
additional data.

European Union Drug Review and Approval

In the European Economic Area (“EEA”) (which is comprised of the 28 Member States of the European Union plus Norway, Iceland and Liechtenstein), medicinal

products can only be commercialized after obtaining a Marketing Authorization (“MA”). There are two types of MA:

26

 
 
 
 
 
 
 
 
 
 
Table of Contents

The Community MA, which is issued by the European Commission through the Centralized Procedure, based on the opinion of the CHMP, or Committee for Medicinal
Products for Human Use, of the European Medicines Agency (“EMA”), is valid throughout the entire territory of the EEA. The Centralized Procedure is mandatory for certain
types of products, such as biotechnology medicinal products, orphan medicinal products, and medicinal products containing a new active substance indicated for the treatment of
AIDS, cancer, neurodegenerative disorders, diabetes and auto-immune and viral diseases. The Centralized Procedure is optional for products containing a new active substance
not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the EU.

National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover their respective territory, are available for products not
falling within the mandatory scope of the Centralized Procedure. Where a product has already been authorized for marketing in a Member State of the EEA, this National MA
can  be  recognized  in  other  Member  States  through  the  Mutual  Recognition  Procedure.  If  the  product  has  not  received  a  National  MA  in  any  Member  State  at  the  time  of
application, it can be approved simultaneously in various Member States through the Decentralized Procedure. Under the above described procedures, before granting the MA,
the  EMA  or  the  competent  authorities  of  the  Member  States  of  the  EEA  make  an  assessment  of  the  risk-benefit  balance  of  the  product  on  the  basis  of  scientific  criteria
concerning its quality, safety and efficacy.

PRIME Designation

The EMA launched its PRIME regulatory initiative to enhance support for the development of therapies that target an unmet medical need. The initiative focuses on
drugs that may offer a major therapeutic advantage over existing treatments, or benefit patients with no treatment options. These therapies are considered priority medicines
within the EU. Through PRIME, the EMA offers early, proactive and enhanced support to drug developers to optimize the generation of robust data on a therapy’s benefits and
risks and enable accelerated assessment of drug applications. MNPR-101 may be eligible for PRIME designation.

Post-Approval Requirements

Any pharmaceutical products for which a sponsor receives FDA approvals are subject to  continuing  regulation  by  the  FDA,  including,  among  other  things,  record-
keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution
requirements, complying with certain electronic records and signature requirements and complying with FDA and FTC promotion and advertising requirements, which include,
among others, standards for direct-to-consumer advertising, prohibitions on promoting pharmaceutical products for uses or in patient populations that are not described in the
pharmaceutical product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities and promotional activities involving the internet.
Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, actions by the U.S. Department of
Justice  and/or  U.S.  Department  of  Health  and  Human  Services  Office  of  Inspector  General,  mandated  corrective  advertising  or  communications  with  doctors,  and  civil  or
criminal  penalties. Although  physicians  may  prescribe  legally  available  pharmaceutical  products  for  off-label  uses,  manufacturers  may  not  directly  or  indirectly  market  or
promote such off-label uses.

Manufacturers of FDA approved products are required to comply with applicable FDA manufacturing requirements contained in the FDA’s cGMP regulations. cGMP
regulations require, among other things, quality control and quality assurance, as well as the corresponding maintenance of records and documentation. Pharmaceutical product
manufacturers and other entities involved in the manufacture and distribution of approved pharmaceutical products are required to register their establishments with the FDA
and certain state agencies, and are subject to periodic unannounced inspections by the 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.  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 withdrawal of the product from the market. In
addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as
adding new indications and additional labeling claims, are also subject to further FDA review and approval. The FDA also may require post-marketing testing, known as Phase
4 testing, risk minimization action plans and surveillance to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or
use of the product.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical product candidates for which we obtain regulatory approval. In the
U.S.  and  markets  in  other  countries,  sales  of  any  products  for  which  we  receive  regulatory  approval  for  commercial  sale  will  depend  in  part  upon  the  availability  of
reimbursement  from  third-party  payers.  Third-party  payers  include  government  payers  such  as  Medicare  and  Medicaid,  managed  care  providers,  private  health  insurers  and
other organizations. The process for determining whether a payer will provide coverage for a pharmaceutical product may be separate from the process for setting the price or
reimbursement rate that the payer will pay for the pharmaceutical product. Third-party payers may limit coverage to specific pharmaceutical products on an approved list, or
formulary, which might not include all of the FDA-approved pharmaceutical products for a particular indication. Third-party payers are increasingly challenging the price and
examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct expensive pharmaco-
economic studies in order to demonstrate the medical necessity and cost-effectiveness of our products, in addition to the costs required to obtain the FDA approvals. A payer’s
decision to provide coverage for a pharmaceutical product does not imply that an adequate reimbursement rate will be approved.

In 2003, the federal government enacted legislation providing a partial prescription drug benefit for Medicare recipients, which became effective at the beginning of
2006. However, to obtain payments under this program, a company would be required to sell products to Medicare recipients through prescription drug plans operating pursuant
to this legislation. As part of their participation in the Medicare prescription drug program, these plans negotiate discounted prices for prescription drugs. Federal, state and local
governments in the U.S. continue to consider legislation to limit the growth of health care costs, including the requirement to reduce the price of certain prescription drugs.
Future legislation and regulations could limit payments for pharmaceuticals such as the product candidates that we are developing.

Different  pricing  and  reimbursement  schemes  exist  in  other  countries.  In  the  European  Community,  governments  influence  the  price  of  pharmaceutical  products
through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those products to consumers. Some jurisdictions
operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed upon. To obtain reimbursement or pricing
approval,  some  of  these  countries  may  require  the  completion  of  clinical  studies  that  compare  the  cost-effectiveness  of  a  particular  pharmaceutical  product  candidate  to
currently available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on
health care costs in general, particularly prescription drugs, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In
addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

International Regulation

In addition to regulations in the U.S., there are a variety of foreign regulations governing clinical studies and commercial sales and distribution of our future product
candidates. Whether or not FDA approval is obtained for a product, approval of a product must be obtained by the comparable regulatory authorities of foreign countries before
clinical studies or marketing of the product can commence in those countries. The approval process varies from country to country, and the time may be longer or shorter than
that required for FDA approval. The requirements governing the conduct of clinical studies, product licensing, pricing and reimbursement vary greatly from country to country.
In addition, certain regulatory authorities in select countries may require us to repeat previously conducted preclinical and/or clinical studies under specific criteria for approval
in their respective country which may delay and/or greatly increase the cost of approval in certain markets targeted for approval by us.

Under  E.U.  regulatory  systems,  marketing  applications  for  pharmaceutical  products  must  be  submitted  under  a  centralized  procedure  to  the  EMA.  The  centralized
procedure provides for the granting of a single marketing authorization that is valid for all E.U. member states. The EMA also has designations for Orphan Drugs, which, if
applicable,  can  provide  for  faster  review,  lower  fees  and  more  access  to  advice  during  drug  development.  While  the  marketing  authorization  in  the  European  Union  is
centralized, the system for clinical studies (application, review and requirements) is handled by each individual country. Approval to run a clinical study in one country does not
guarantee approval in any other country. The pharmaceutical industry in Canada is regulated by Health Canada. A New Drug Submission (“NDS”) is the equivalent of a U.S.
NDA and must be filed to obtain approval to market a pharmaceutical product in Canada. Marketing regulations and reimbursement are subject to national and provincial laws.
In Japan, applications for approval to manufacture and market new drugs must be approved by the Ministry of Health, Labor and Welfare. Nonclinical and clinical studies must
meet the requirements of Japanese laws. Results from clinical studies conducted outside of Japan must be supplemented with at least a bridging clinical study conducted in
Japanese patients.

Table of Contents

In  addition  to  regulations  in  Europe,  Canada,  Japan  and  the  U.S.,  there  are  a  variety  of  foreign  regulations  governing  clinical  studies,  commercial  distribution  and
reimbursement of future product candidates which we may be subject to as we pursue regulatory approval and commercialization of Validive, camsirubicin, MNPR-101, or any
future product candidates internationally.

Compliance with Environmental Laws

Since we do not have our own laboratory or manufacturing facilities, we do not estimate any annual costs of compliance with environmental laws.

Employees

Our operations are currently managed by five individuals (including our executive chairman and our Acting Chief Medical Officer), of whom two have a PhD, two
have an MD, two have an MBA, one has an MSc in health economics and policy, one has an MS from Stanford University, and one is a former CPA. They have worked at
industry  leading  companies  such  as  BioMarin  Pharmaceutical  Inc.,  Raptor  Pharmaceuticals,  and  Onyx  Pharmaceuticals. As  of  March  10,  2023,  we  had  twelve  employees;
eleven of whom were full-time. We anticipate hiring additional employees in clinical operations, regulatory affairs and other departments, to help manage our clinical studies,
regulatory  submissions,  and  manufacturing  to  support  Validive  and  camsirubicin  program  development,  business  development  and  corporate  strategy.  In  addition,  to
complement our internal expertise, we have contracts with medical and scientific consultants, manufacturers, laboratories, and contract research organizations that specialize in
various aspects of drug development including clinical development, preclinical development, manufacturing, quality assurance, and regulatory affairs.

Item 1A. Risk Factors

RISK FACTORS

An  investment  in  our  common  stock  involves  a  high  degree  of  risk. A  prospective  investor  should  carefully  consider  the  following  information  about  these  risks,
together  with  other  information  appearing  elsewhere  in  this Annual  Report  on  Form  10-K,  before  deciding  to  invest  in  our  common  stock.  The  occurrence  of  any  of  the
following risks could have a material adverse effect on our business, financial condition, results of operations and future prospects and prospective investors could lose all or
part of their investment. The risk factors discussed below and elsewhere in this Annual Report on Form 10-K are not exhaustive; other significant risks may exist that are not
identified in this Annual Report on Form 10-K, but that might still materially and adversely affect our business, prospects, financial condition, and results of operations were
any of such risks to occur.

Risks Related to Our Financial Condition and Capital Requirements

We have a limited operating history, expect to incur significant operating losses, and have a high risk of never being profitable.

We commenced operations in December 2014 and have an operating history of approximately eight years. Therefore, there is limited historical financial or operational
information upon which to evaluate our performance. Our prospects must be considered in light of the uncertainties, risks, expenses, and difficulties frequently encountered by
companies  in  their  early  clinical  stages  of  operations.  Many,  if  not  most,  companies  in  our  industry  at  our  stage  of  development  never  become  profitable  and  are  acquired,
merge, sell major product assets or go out of business before successfully developing any product that generates revenue from commercial sales and enables profitability.

From inception in December 2014 through December 31, 2022, we have incurred losses of approximately $51.8 million, which includes $13.5 million of non-cash in-
process research and development, which was incurred in connection with our 2017 acquisition of camsirubicin. We expect to continue to incur substantial operating losses over
the next several years for the clinical development of our current and future licensed or purchased product candidates and will continue to incur losses for the foreseeable future.
We expect that our R&D and G&A expenses will increase to enable the execution of our strategic plan. As a result, we anticipate that we will seek to raise additional capital
within the next 12 months to fund our future operations. We will seek to obtain needed capital through a combination of equity offerings, including the usage of our Capital on
DemandTM Sales Agreement with JonesTrading, debt financings, strategic collaborations and grant funding. To date, we have funded our operations through net proceeds from
the initial public offering of our common stock, net proceeds from sales of our common stock through an at-the-market sales program, private placements of our preferred and
common stock, and the net receipt of funds related to our acquisition of camsirubicin and related assets.

The amount of future losses and when, if ever, we will become profitable are uncertain. We do not have any products that have generated revenues from commercial
sales, and do not expect to generate revenues from the commercial sale of products in the near future, if ever. Our ability to generate revenue and achieve profitability will
depend on, among other things, successful completion of the development of our product candidates; obtaining necessary regulatory approvals from the FDA and international
regulatory agencies; establishing manufacturing/quality, sales, and marketing and distribution arrangements with third parties; obtaining adequate reimbursement by third-party
payers;  and  raising  sufficient  funds  to  finance  our  activities.  If  we  are  unsuccessful  at  some  or  all  of  these  undertakings,  our  business,  financial  condition,  and  results  of
operations are expected to be materially and adversely affected.

30

 
 
 
 
 
 
 
 
 
 
Table of Contents

We will need to raise substantial additional funding or find a suitable pharmaceutical partner to continue to advance our clinical programs and support our preclinical
activities.

In  order  to  be  commercially  viable,  we  must  successfully  research,  develop,  test,  obtain  regulatory  approval  for,  manufacture,  introduce,  market  and  distribute
Validive, camsirubicin, MNPR-101-Zr, MNPR-101 RIT, MNPR-202, and, if applicable, any current and future product candidates we may develop. The estimated required
capital and time-frames necessary to achieve these developmental milestones as described in this Annual Report on Form 10-K or as we may state from time to time is subject
to inherent risks, which are beyond our control. Clinical development of Validive, camsirubicin, MNPR-101-Zr, MNPR-101 RIT, and MNPR-202 will require significant funds.
Proceeds to-date from the sales of our common stock we believe could be sufficient for us to complete our ongoing open-label Phase 1b camsirubicin clinical trial (but this may
not be the case if camsirubicin reaches even higher dose levels than we are anticipating)  and, assuming a positive result of the go/no go interim analysis decision anticipated by
the end of March 2023, continue enrolling the Phase 3 portion of our ongoing Validive Phase 2b/3 (VOICE) clinical program, but will not be sufficient for us to complete our
VOICE clinical program, including if we need to run a second confirmatory Phase 3 clinical trial and support further development through and beyond our ongoing Phase 1b
camsirubicin  clinical  trial.  To  complete  the  VOICE  clinical  program,  including,  if  required,  completing  a  second  Phase  3  confirmatory  clinical  trial,  we  will  need  to  raise
additional funding in the millions or tens of millions of dollars. Therefore, we will need to raise significant additional funds or find a suitable pharmaceutical partner within the
next 12 months to complete the VOICE clinical program, as well as support further development of camsirubicin through and beyond our ongoing Phase 1b, to support MNPR-
101-Zr,  MNPR-101  RIT  and  MNPR-202  and  related  compounds  in  various  indications  and  generally  to  support  our  current  and  any  future  product  candidates  through
completion of clinical trials, approval processes and, if applicable, commercialization, If we are able to raise financing, it may be on terms that are unfavorable to us and if we
are unable to raise sufficient funds or find a suitable pharmaceutical partner, we may have to discontinue or delay clinical development of Validive and/or any other of our
current or future product candidates.

If the interim analysis for our ongoing Validive Phase 2b/3 clinical program yields a no-go decision, our business would be adversely impacted.

This interim analysis for our ongoing Validive Phase 2b/3 clinical program, and the resulting go/no-go decision about whether to proceed to the Phase 3 portion of the
trial, is expected by the end of March 2023. Because the interim analysis is being performed by an independent data monitoring committee, we do not know what the results will
be as of the date of this Annual Report. If the interim analysis results in a no-go decision, we would need to reconsider our efforts with respect to Validive and refocus our
development efforts on our other product candidates. Validive has been our lead product candidate to date and is the most clinically advanced, and if we had to reconsider or
abandon our efforts, it would likely materially adversely impact our financing prospects, as well as the price of our common stock.

Our operations and financial results could be adversely impacted by COVID-19, which may negatively impact our ability to manufacture our product candidates for our
clinical  trials,  our  ability  to  accrue  and  conduct  our  clinical  trials,  and  may  delay  regulatory  agency  responses.  Any  such  impact  will  negatively  impact  our  financial
condition and could require us to delay our clinical development programs.

In response to COVID-19 and its effects on clinical trials, we modified the original adaptive design Phase 3 clinical trial for our lead product candidate, Validive, in
2020 to be a Phase 2b/3 VOICE clinical trial to better fit the types of trials which can enroll patients in the current environment. We have activated sites and commenced dosing
in  our  VOICE  clinical  program.  We  completed  enrollment  of  the  Phase  2b  portion  of  the  trial  and  commenced  enrollment  of  the  Phase  3  portion  of  the  VOICE  trial.  To
complete VOICE clinical program, including, if required, completing a second Phase 3 confirmatory clinical trial, we will need to raise additional funding in the millions or tens
of millions of dollars (depending on if we have consummated a collaboration or partnership or neither for Validive), or find a suitable pharmaceutical partner, both of which we
are  planning  to  pursue  within  the  next  12  months.  There  can  be  no  assurance  that  any  such  events  will  occur,  and  the  long-term  effects  of  COVID-19  continue  to  create
uncertainties and challenges to our ability to seek additional funding and explore collaborations and partnerships.

While we are currently continuing our ongoing clinical trials, COVID-19 and related precautions have directly or indirectly impacted the timeline for certain of our
clinical trials. We are continuing to monitor the impact of COVID-19 on our operations and ongoing clinical development activity, generally. As a result of COVID-19, we may
experience further disruptions that could severely impact our business, preclinical studies and clinical trials, including:

●

●

●

●

Delays in receiving approval from the FDA and foreign regulatory authorities to initiate our planned clinical trials;

Delays or difficulties in enrolling and monitoring patients in our clinical trials;

Delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

Delays in trial drug shipments due to COVID-19 vaccine shipments tying up available pharmaceutical product shipping lanes and increasing their cost;

Diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff
supporting the conduct of our clinical trials;

Risk that participants enrolled in our clinical trials will acquire COVID-19 while the clinical trial is ongoing, which could impact the results of the clinical trial,
including by increasing the number of observed adverse events;

Interruption  of  key  clinical  trial  activities,  such  as  clinical  trial  site  data  monitoring,  due  to  limitations  on  travel  imposed  or  recommended  by  federal  or  state
governments, employers and others or interruption of clinical trial subject visits and study procedures, which may impact the integrity of subject data and clinical
study endpoints;

Interruption or delays in the operations of the FDA and foreign regulatory agencies, which may impact approval timelines;

Interruption  of,  or  delays  in  receiving,  supplies  of  our  product  candidates  from  our  contract  manufacturing  organizations  due  to  staffing  or  supply  shortages,
production slowdowns, global shipping delays or stoppages and disruptions in delivery systems;

Limitation on employee resources that would otherwise be focused on the conduct of our preclinical studies and clinical trials, including because of sickness of
our employees or their families or the desire of employees to avoid contact with large groups of people.

Refusal of the FDA to accept data from clinical trials in affected geographies; and

Impacts from prolonged remote work arrangements, such as increased cybersecurity risks.

The  extent  to  which  the  long-term  effects  of  COVID-19  further  impacts  our  business,  including  our  preclinical  studies  and  clinical  trials,  results  of  operations  and
financial condition will depend on future developments which remain highly uncertain and cannot be predicted with confidence. Such factors include but are not limited to the
global availability and acceptability of available vaccinations, the continued efficacy of available vaccines and treatments, the potential and duration of another major outbreak
and  the  impacts  of  new  variations  of  the  virus,  continued  or  reimplemented  travel  restrictions,  local  states  of  emergency  requiring  quarantines  and  shelter-in-place  orders,
adherence to social distancing and mask-wearing recommendations in the U.S. and other countries and the availability of effective global therapeutics to treat COVID-19.

The Russia-Ukraine war will likely have continuing global effects on fuel costs and shipping and broader impacts on economic, trade and financial market conditions,
which  could  delay  the  shipping  of  supplies  for  our  clinical  material  manufacturing,  potentially  resulting  in  increased  manufacturing  expenses,  delays  to  our  clinical
programs and adverse effects on our financing activities and financial condition.

The  Russia-Ukraine  war  is  a  volatile  situation,  resulting  in  financial  services  and  banking  instability  in  the  region.  The  U.S.  and  other  countries’  sanctions  against
Russia and Russian entities, together with existing inflationary conditions and supply chain challenges arising in the wake of COVID-19, are affecting fuel costs and shipping,
resulting  in  higher  costs  and  delays  for  various  types  of  supplies.  These  cost  increases  and  delays  may  affect  our  clinical  material  manufacturing  which  will  likely  have  an
adverse effect on our financial condition. In addition, at this stage, we are unable to predict whether the war will have broader adverse impacts to European, U.S. or global
economic,  trade  and  financial  market  conditions,  which  could  adversely  affect  our  operations  and  financial  condition  in  a  variety  of  ways.  In  particular,  financial  market
instability or volatility may make it more difficult to raise required financing.

If we continue to incur operating losses and fail to obtain the capital necessary to fund our operations, we will be unable to advance our development programs, complete
our clinical trials, or bring products to market, or may be forced to reduce or cease operations entirely. In addition, any capital obtained by us may be obtained on terms
that are unfavorable to us, our investors, or both.

While we believe adequate cash is currently available to operate for the next twelve months, developing a new drug and conducting clinical trials and the regulatory
review processes for one or more disease indications involves substantial costs. We have projected cash requirements for the near term based on a variety of assumptions, but
some or all of such assumptions are likely to be incorrect and/or incomplete, possibly materially in an adverse direction. Our actual cash needs may deviate materially from
those  projections,  changes  in  market  conditions  or  other  factors  may  increase  our  cash  requirements,  or  we  may  not  be  successful  even  in  raising  the  amount  of  cash  we
currently project will be required for the near term. We will need to raise additional capital in the future; the amount of additional capital needed will vary as a result of a number
of factors, including without limitation the following:

●

●

●

●

●

●

●

●

receiving less funding than we require;

higher than expected costs to manufacture and ship our active pharmaceutical ingredient and our product candidates;

higher than expected costs for preclinical testing;

an increase in the number, size, duration, and/or complexity of our clinical trials;

slower than expected progress in developing Validive, camsirubicin, MNPR-101-Zr, MNPR-101 RIT, MNPR-202 or other product candidates, including without
limitation, additional costs caused by program delays;

higher than expected costs associated with attempting to obtain regulatory approvals, including without limitation additional costs caused by additional regulatory
requirements or larger clinical trial requirements;

higher than expected personnel, consulting or other costs, such as adding personnel or industry expert consultants or pursuing the licensing/acquisition of
additional assets; and

higher than expected costs to protect our intellectual property portfolio or otherwise pursue our intellectual property strategy.

When we attempt to raise additional financing, there can be no assurance that we will be able to secure such additional financing in sufficient quantities or at all. We
may  be  unable  to  raise  additional  capital  for  reasons  including,  without  limitation,  our  operational  and/or  financial  performance,  investor  confidence  in  us  and  the
biopharmaceutical  industry,  credit  availability  from  banks  and  other  financial  institutions,  the  status  of  current  projects,  and  our  prospects  for  obtaining  any  necessary
regulatory approvals. General economic and financial market conditions, which have recently been impacted by inflation, bank instability and other factors, can also adversely
impact our ability to raise additional financing. Potential investors’ capital investments may have shifted to other opportunities with perceived greater returns and/or lower risk,
thereby reducing capital available to us, if available at all.

In addition, any additional financing might not be available, and even if available, may not be available on terms acceptable to us or our then-existing investors. We
will  seek  to  raise  funds  through  public  or  private  equity  offerings,  including  the  usage  of  our  Capital  on  DemandTM Sales Agreement  with  JonesTrading,  debt  financings,
corporate collaboration or licensing arrangements, mergers, acquisitions, sales of intellectual property, or other financing vehicles or arrangements. To the extent that we raise
additional capital by issuing equity securities or other securities, our then-existing investors will experience dilution. If we raise funds through debt financings or bank loans, we
may become subject to restrictive covenants, our assets may be pledged as collateral for the debt, and the interests of our then-existing investors would be subordinated to the
debt  holders  or  banks.  In  addition,  our  use  of  and  ability  to  exploit  assets  pledged  as  collateral  for  debt  or  loans  may  be  restricted  or  forfeited.  To  the  extent  that  we  raise
additional funds through collaboration or licensing arrangements, we may be required to relinquish significant rights (including without limitation intellectual property rights) to
our technologies or product candidates, or grant licenses on terms that are not favorable to us. If we are not able to raise needed funding under acceptable terms or at all, then we
will have to reduce expenses, including the possible options of curtailing operations, abandoning opportunities, licensing or selling off assets, reducing costs to a point where
clinical development or other progress is impaired, or ceasing operations entirely.

Market variables, such as inflation of product costs, labor rates and fuel, freight and energy costs, as well as geopolitical events could likely cause us to suffer significant
increases in our operating and administrative expenses.

In the wake of the COVID-19 pandemic, the Russia-Ukraine war and other geopolitical factors, economic conditions have become strained, with inflation and supply
chain challenges impacting businesses worldwide. These conditions affect fuel costs and shipping, resulting in higher costs and delays for various types of supplies. These cost
increases and delays may affect our clinical material manufacturing which will likely have an adverse effect on our financial condition. In addition, the effects of responses to
inflationary  conditions,  such  as  significantly  increased  interest  rates,  on  the  economy  and  market  conditions  are  difficult  to  predict.  If  U.S.  or  global  economic,  trade  and
financial market conditions continue to be challenged or volatile, or we do not effectively manage our response to these conditions, our operations and financial condition could
be adversely affected in a variety of ways.

Unstable  market  and  economic  conditions  may  have  serious  adverse  consequences  on  our  ability  to  raise  funds,  which  may  cause  us  to  delay,  restructure  or  cease  our
operations.

From  time  to  time,  global  and  domestic  credit  and  financial  markets  have  experienced  extreme  disruptions,  including  severely  diminished  liquidity  and  credit
availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. Recently, COVID-19
and the Russia-Ukraine war have created volatility and uncertainty.  Recent instability in the banking industry has added to the volatility and uncertainty. Our financing strategy
will be adversely affected by any such economic downturn, volatile business environment and continued unpredictable and unstable market conditions. If the equity and credit
markets deteriorate, it may make a debt or equity financing more difficult to complete, costlier, and more dilutive. Failure to secure any necessary financing in a timely manner
and on favorable terms will have a material adverse effect on our business strategy and financial performance, and could require us to cease or delay our operations.

Risks Related to Clinical Development and Regulatory Approval

We do not have and may never have any approved products on the market. Our business is highly dependent upon receiving approvals from various U.S. and international
governmental agencies and will be severely harmed if we are not granted approval to manufacture and sell our product candidates.

In order for us to commercialize any treatment for chemoradiation-induced SOM, cancer or any other disease indication, we must obtain regulatory approvals of such
treatment for that indication. Satisfying regulatory requirements is an expensive process that takes many years and involves compliance with requirements covering research
and  development,  testing,  manufacturing,  quality  control,  labeling  and  promotion  of  drugs  for  human  use.  To  obtain  necessary  regulatory  approvals,  we  must,  among  other
requirements, complete clinical trials demonstrating that our products are safe and effective for a particular indication. There can be no assurance that our products will prove to
be safe and effective, that our clinical trials will demonstrate the necessary safety and effectiveness of our product candidates, or that we will succeed in obtaining regulatory
approval for any treatment we develop even if such safety and effectiveness are demonstrated.

Any delays or difficulties we encounter in our clinical trials may delay or preclude regulatory approval from the FDA or from international regulatory organizations.
Any delay or preclusion of regulatory approval would be expected to delay or preclude the commercialization of our products. Examples of delays or difficulties that we may
encounter in our clinical trials include without limitation the following:

●

●

●

●

●

Clinical trials may not yield sufficiently conclusive results for regulatory agencies to approve the use of our products.

Our products may fail to be more effective than current therapies, or to be effective at all.

We may discover that our products have adverse side effects, which could cause our products to be delayed or precluded from receiving regulatory approval or
reduce the effective size of our target patient population or otherwise expose us to significant commercial and legal risks.

It may take longer than expected to determine whether or not a treatment is safe and effective.

Patients involved in our clinical trials may suffer severe adverse side effects even up to death, whether as a result of treatment with our products, the withholding
of such treatment, or other reasons which may not include the effects of our treatment (whether within or outside of our control).

We may fail to be able to enroll a sufficient number of patients in our clinical trials to meet trial statistical plans and gain statistical significance, or it may take
longer than expected to enroll.

Patients  enrolled  in  our  clinical  trials  may  not  have  the  safety  or  efficacy  characteristics  necessary  to  obtain  regulatory  approval  for  a  particular  indication  or
patient population.

We may be unable to produce sufficient quantities of product to complete the clinical trials.

Even if we are successful in our clinical trials, required governmental approvals may still not be obtained or, if obtained, may not be maintained.

If approval for commercialization is granted, it is possible the authorized use will be more limited than is necessary for commercial success, or that approval may
be  conditioned  on  completion  of  further  clinical  trials  or  other  activities,  which  will  cause  a  substantial  increase  in  costs  and  which  we  might  not  succeed  in
performing or completing.

If granted, approval may be withdrawn or limited if problems with our products emerge or are suggested by the data arising from their use or if there is a change
in law or regulation.

Any success we may achieve at a given stage of our clinical trials does not guarantee that we will achieve success at any subsequent stage, including without limitation

final FDA or other regulatory organizations’ approval.

We  may  encounter  delays  or  rejections  in  the  regulatory  approval  process  because  of  additional  government  regulation  resulting  from  future  legislation  or
administrative action, or  from  changes  in  the  policies  of  the  FDA  or  other  regulatory  bodies  during  the  period  of  product  development,  clinical  trials,  or  regulatory  review.
Failure  to  comply  with  applicable  regulatory  requirements  may  result  in  criminal  prosecution,  civil  penalties,  recall  or  seizure  of  products,  total  or  partial  suspension  of
production,  or  an  injunction  preventing  certain  activity,  as  well  as  other  regulatory  action  against  our  product  candidates  or  us. As  a  company,  we  have  no  experience  in
successfully obtaining regulatory approval for a product and thus may be poorly equipped to gauge, and may prove unable to manage, risks relating to obtaining such approval.

Outside  the  U.S.,  our  ability  to  market  a  product  is  contingent  upon  receiving  clearances  from  appropriate  non-U.S.  regulatory  authorities.  Non-U.S.  regulatory
approval typically includes all of the risks associated with FDA clearance discussed above as well as geopolitical uncertainties and the additional uncertainties and potential
prejudices  faced  by  U.S.  pharmaceutical  companies  conducting  business  abroad.  In  certain  cases,  governmental  pricing  restrictions  and  practices  can  make  achieving  even
limited profitability very difficult.

Even  if  we  complete  the  clinical  trials  we  discussed  with  the  FDA,  there  is  no  guarantee  that  at  the  time  of  submission  the  FDA  will  accept  our  new  drug  application
(“NDA”) based on the trials discussed.

The FDA provided guidance on our proposed VOICE trial, but the FDA is not bound by the guidance they give, and can change their position in the future. Any future
decision by the FDA will be driven largely by the data generated from the VOICE clinical program. However, the FDA and other regulatory organizations will learn from their
total experience in the review of multiple drugs in multiple indications and they will apply the knowledge of broad and diverse experience even if less than a perfect match with
our product.

As a company, we have never completed a clinical trial and have limited experience in completing regulatory filings and any delays in regulatory filings could materially
affect our financial condition.

While members of our team have conducted numerous clinical trials at previous companies, and have launched and marketed innovative pharmaceutical products in
the U.S. and internationally, as a company, we have not yet completed any clinical trials of our product candidates, nor have we demonstrated the ability to obtain marketing
approvals,  manufacture  product  candidates  at  a  commercial  scale,  or  conduct  sales  and  marketing  activities  necessary  for  the  successful  commercialization  of  a  product.
Consequently, we have no historical basis as a company by which one can evaluate or predict reliably our future success or viability.

Additionally, while our team has experience at prior companies with regulatory filings, as a company, we have limited experience with regulatory filings with agencies
such as the FDA or EMA. Any delay in our regulatory filings for our 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  “refuse  to  file”  letter  or  a  request  for  additional  information,
could materially affect our financial condition.

We  may  seek  fast  track  designation  for  one  or  more  of  our  current  and  future  product  candidates,  but  we  might  not  receive  such  designation,  and  even  if  we  do,  such
designation may not actually lead to a faster development or regulatory review or approval process.

Our  lead  product  candidate,  Validive,  has  been  given  fast  track  designation  from  the  FDA.  Fast  track  designation  does  not  ensure  that  we  will  receive  marketing
approval or that approval will be granted within any particular timeframe. We may not experience a faster development, regulatory review or approval process with fast track
designation compared to conventional FDA procedures. Additionally, the FDA may withdraw fast track designation, for reasons such as it comes to believe a drug candidate no
longer adequately addresses an unmet medical need. Fast track designation alone does not guarantee qualification for the FDA’s priority review procedures. If we seek fast track
designation for other product candidates, we may not receive such a designation from the FDA.

We, or any future collaborators, may not be able to obtain and maintain orphan drug exclusivity for our product candidates in the U.S. and Europe.

Validive has been granted orphan drug designation for the treatment of SOM in the EU. Camsirubicin has been granted orphan drug designation for the treatment of soft
tissue sarcoma in the U.S. and in the EU. We may seek additional orphan drug designations or regulatory incentives for our pipeline product candidates, for other indications or
for future product candidates. There can be no assurances that we will be able to obtain such designations.

Even if we obtain orphan drug designation for a product candidate, we may not be able to maintain orphan drug exclusivity for that drug. For example, orphan drug
designation may be removed if the prevalence of an indication increases beyond the patient number limit required to maintain designation. Generally, if a drug with an orphan
drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity,
which precludes the EMA or the FDA from approving another marketing application for the same product in the same indication for that time period. Orphan drug exclusivity
may be lost if the FDA or EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity at the specified
quality of the product to meet the needs of patients with the rare disease or condition. Moreover, even after an orphan drug is approved, the FDA can subsequently approve a
different drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to
patient care compared to our product.

The FDA may reevaluate the Orphan Drug Act and its regulations and policies, and similarly the EMA may reevaluate its policies and regulations. We do not know if,
when, or how the FDA or EMA may change their orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending
on what changes the FDA and/or EMA may make to their orphan drug regulations and policies, our business could be adversely impacted.

If  serious  adverse  or  undesirable  side  effects  are  identified  during  the  development  of  our  product  candidates,  we  may  abandon  or  limit  our  development  or
commercialization of such product candidates.

If  our  product  candidates  are  associated  with  undesirable  side  effects  or  have  unexpected  characteristics,  we  may  need  to  abandon  their  development  or  limit
development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit
perspective.

If we elect to or are forced to suspend or terminate any clinical trial with one of our product candidates, the commercial prospects of such product candidate will be
harmed, and our ability to generate revenue from such product candidate will be delayed or eliminated. Any of these occurrences may harm our business, financial condition
and prospects significantly.

36

With regard to our lead product candidate, unforeseen side effects from Validive could arise either during clinical development or, if approved, after Validive has been

marketed. This could cause regulatory approvals for, or market acceptance of, Validive to be harder and costlier to obtain.

To date, no difference in the frequency of serious adverse events (“SAEs”) has been observed in patients treated with Validive compared to placebo. In the Phase 2
clinical trial, two patients in the placebo group and 2 patients in the Validive 50 µg group experienced SAEs that were assessed as treatment related. No patients in the Validive
treated cohorts were discontinued due to the study drug. Clonidine, the active ingredient of Validive, has been used for over 50 years as an orally swallowed systemic treatment
for high blood pressure. Validive administration leads to very low, but still detectable exposure of clonidine outside the oral cavity. Thus, there is some risk that patients may
experience side effects due to this systemic exposure, which could include a reduction in blood pressure, irregular heartbeat, drowsiness or dry mouth.

The results of our current or any future clinical trials may show that the side effects of Validive are unacceptable or intolerable, which would interrupt, delay or halt
clinical trials, and result in delay of, or failure to obtain, marketing approval from the FDA or EMA and other regulatory authorities, or result in marketing approval from the
FDA or EMA and other regulatory authorities with restrictive label warnings.

If Validive receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by the use of Validive:

regulatory authorities may withdraw their approval of the product, which would force us to remove Validive from the market;

regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication, or field alerts to physicians and pharmacies;

we may be required to change instructions regarding the way the product is administered, conduct additional clinical trials or change the labeling of the product;

we may be subject to limitations on how we may promote the product;

sales of the product may decrease significantly;

we may be subject to litigation or product liability claims; and

our reputation may suffer.

●

●

●

●

●

●

●

Any  of  these  events  could  prevent  us  or  our  potential  future  collaborators  from  achieving  or  maintaining  market  acceptance  of  Validive  and/or  could  substantially

increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of Validive.

As with any clinical trial, our VOICE clinical program entails significant risk of not meeting clinical endpoints. If the results of VOICE are not statistically significant, the
FDA will likely not approve Validive for marketing which will result in a decrease in our stock price and market value.

The  VOICE  clinical  program  has  been  designed  based  on  an  analysis  of  the  64  oropharyngeal  cancer  (“OPC”)  patients  included  in  the  Phase  2  trial  (n=  24  in  the
placebo group, n= 21 Validive 50 µg group, and n= 19 Validive 100 µg group). While a dose response was observed in the Validive treated OPC cohorts compared to placebo
across multiple clinically meaningful endpoints, the ability to establish statistical significance was limited by the relatively small sample size. This increases the risk that the
VOICE trial may not achieve its prospectively defined endpoints. VOICE includes an interim analysis after the 2b portion that allows for an assessment of the primary (and
only) endpoint, incidence of SOM, before proceeding to the Phase 3 portion of the trial. This interim analysis, and the resulting go/no-go decision about whether to proceed to
the Phase 3 portion of the trial, is expected by the end of March 2023. If the interim analysis results in a  no-go decision, we would need to reconsider our efforts with respect to
Validive and refocus our development efforts on our other product candidates. Validive has been our lead product candidate to date and is the most clinically advanced, and if
we had to reconsider or abandon our efforts, it would likely materially adversely impact our financing prospects, as well as the price of our common stock. Because the interim
analysis is being performed by an independent data monitoring committee, we do not know what the results will be as of the date of this Annual Report. Assuming positive
results from the interim analysis and that we fully proceed to the Phase 3 portion of the trial, we may also be required by the FDA to conduct a second Phase 3 confirmatory
clinical trial which may not yield the same results. If our VOICE clinical trial results are not statistically significant, the FDA will likely not approve Validive for marketing,
which will result in a decrease in our stock price and market value.

If we experience delays or difficulties in the enrollment of subjects to our clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented, which
could materially affect our financial condition.

Identifying,  screening  and  enrolling  patients  to  participate  in  clinical  trials  of  our  product  candidates  is  critical  to  our  success,  and  we  may  not  be  able  to  identify,
recruit, enroll and dose a sufficient number of patients with the required or desired characteristics to complete our clinical trials in a timely manner. The timing of our clinical
trials depends on our ability to recruit patients to participate as well as to subsequently dose these patients and complete required follow-up periods. In particular, because our
current clinical trials of Validive and camsirubicin are focused on indications with relatively small patient populations, our ability to enroll eligible patients may be limited or
may result in slower enrollment than we anticipate.

In  addition,  we  may  experience  enrollment  delays  related  to  increased  or  unforeseen  regulatory,  legal  and  logistical  requirements  and  COVID-19-related  issues  at
certain  clinical  trial  sites.  These  delays  could  be  caused  by  reviews  by  regulatory  authorities  and  contractual  discussions  with  individual  clinical  trial  sites. Any  delays  in
enrolling and/or dosing patients in our current clinical trials could result in increased costs, delays in advancing our product candidates, delays in testing the effectiveness of our
product candidates or in termination of the clinical trials altogether.

Patient enrollment may be affected if our competitors have ongoing clinical trials with products for the same indications as our product candidates, and patients who

would otherwise be eligible for our clinical trials instead enroll in our competitors’ clinical trials. Patient enrollment may also be affected by other factors, including:

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

●

delays in U.S. or foreign regulatory approvals to start the clinical trial;

Our inability to enroll a sufficient number of patients for clinical trials would result in significant delays and could require us to abandon one or more clinical trials
altogether. Enrollment delays in these clinical trials may result in increased development costs for our product candidates, which could materially affect our financial condition.

If we or our licensees, development collaborators, or suppliers are unable to manufacture our products in sufficient quantities or at defined quality specifications, or are
unable  to  obtain  regulatory  approvals  for  the  manufacturing  facility,  we  may  be  unable  to  develop  and/or  meet  demand  for  our  products  and  lose  time  to  market  and
potential revenues.

Completion of our clinical trials and commercialization of our product candidates require access to, or development of, facilities to manufacture a sufficient supply of
our product candidates. We will utilize third parties to manufacture Validive, camsirubicin, and MNPR-101. We currently have manufacturing arrangements for Validive and
camsirubicin. We have not yet secured  manufacturing agreements for MNPR-101-Zr, MNPR-101 RIT or MNPR-202.

In the future we may become unable, for various reasons, to rely on our sources for the manufacture of our product candidates, either for clinical trials or, at some future
date, for commercial distribution. We may not be successful in identifying additional or replacement third-party manufacturers, or in negotiating acceptable terms with any we
do identify. We may face competition for access to these manufacturers’ facilities and may be subject to manufacturing delays if the manufacturers give other clients higher
priority  than  they  give  to  us.  Even  if  we  are  able  to  identify  an  additional  or  replacement  third-party  manufacturer,  the  delays  and  costs  associated  with  establishing  and
maintaining a relationship with such manufacturer may have a material adverse effect on us.

Before we can begin to commercially manufacture Validive, camsirubicin, MNPR-101-Zr, MNPR-101 RIT, MNPR-202 or any other product candidate, we must obtain
regulatory approval of the manufacturing facility and process. Manufacturing of drugs for clinical and commercial purposes must comply with current Good Manufacturing
Practices requirements, commonly known as “cGMP.” The cGMP requirements govern quality control and documentation policies and procedures. Complying with cGMP and
non-U.S.  regulatory  requirements  will  require  that  we  expend  time,  money,  and  effort  in  production,  recordkeeping,  and  quality  control  to  ensure  that  the  product  meets
applicable specifications and other requirements. We, or our contracted manufacturing facility, must also pass a pre-approval inspection prior to FDA approval. Failure to pass a
pre-approval inspection will likely significantly delay or prevent FDA approval of our products. If we fail to comply with these requirements, we would be subject to possible
regulatory action and may be limited in the jurisdictions in which we are permitted to sell our products and will lose time to market and potential revenues.

It is uncertain whether product liability insurance will be adequate to address product liability claims, or that insurance against such claims will be affordable or available
on acceptable terms in the future.

Clinical research involves the testing of new drugs on human volunteers pursuant to a clinical trial protocol. Such testing involves a risk of liability for personal injury
to  or  death  of  patients  due  to,  among  other  causes,  adverse  side  effects,  improper  administration  of  the  new  drug,  or  improper  volunteer  behavior.  Claims  may  arise  from
patients,  clinical  trial  volunteers,  consumers,  physicians,  hospitals,  companies,  institutions,  researchers,  or  others  using,  selling,  or  buying  our  products,  as  well  as  from
governmental bodies including a possibility in some states for product liability claims being made based on generic copies of our drugs. In addition, product liability and related
risks are likely to increase over time, in particular upon the commercialization or marketing of any products by us or parties with which we enter into development, marketing,
or distribution collaborations. Although we have obtained product liability insurance in connection with our clinical trials, there can be no assurance that the amount and scope
of such insurance coverage will be appropriate and sufficient in the event any claims arise, that we will be able to secure additional coverage should we attempt to do so, or that
our insurers would not contest or refuse any attempt by us to collect on such insurance policies. Regardless of their merit or eventual outcome, product liability claims may
result in:

withdrawal of clinical trial volunteers;

decreased demand for our products when approved;

injury to our reputation and significant, adverse media attention; and

potentially significant litigation costs, including without limitation, any damages awarded to the plaintiffs if we lose or settle claims.

If  the  market  opportunities  for  our  current  and  potential  future  drug  candidates  are  smaller  than  we  believe  they  are,  our  ability  to  generate  product  revenues  will  be
adversely affected and our business may suffer.

Our understanding of the number of people who suffer from SOM resulting from CRT for the treatment of OPC, whom Validive may have the potential to treat, is
based upon estimates and on various reports from governments or medical institutions. These estimates or reports may prove to be incorrect, and new studies may demonstrate
or suggest a lower estimated incidence or prevalence of this condition. The number of patients in the U.S. or elsewhere may turn out to be lower than expected, may not be
otherwise amenable to Validive treatment, or treatment-amenable patients may become increasingly difficult to identify and access, all of which would adversely affect our
business prospects and financial condition. In particular, the treatable population for Validive may further be reduced if our estimates of addressable populations are erroneous
or sub-populations of patients within the addressable population do not derive benefit from Validive.

Risks Related to Our Reliance on Third Parties

Corporate, non-profit, and academic collaborators may take actions (including lack of effective actions) to delay, prevent, or undermine the success of our products.

Our  operating  and  financial  strategy  for  the  development,  clinical  testing,  manufacture,  and  commercialization  of  product  candidates  is  heavily  dependent  on  us
entering into collaborations with corporations, non-profit organizations, academic institutions, licensors, licensees, and other parties. There can be no assurance that we will be
successful  in  establishing  such  collaborations.  Current  and  future  collaborations  are  and  may  be  terminable  at  the  sole  discretion  of  the  collaborator.  The  activities  of  any
collaborator will not be within our direct control and may not be in our power to influence. There can be no assurance that any collaborator will perform its obligations to our
satisfaction or at all; that we will derive any revenue, profits, or benefit from such collaborations; or that any collaborator will not compete with us. If any collaboration is not
pursued,  we  may  require  substantially  greater  capital  to  undertake  development  and  commercialization  of  our  proposed  products,  and  may  not  be  able  to  develop  and
commercialize  such  products  effectively,  if  at  all.  In  addition,  a  lack  of  development  and  commercialization  collaborations  may  lead  to  significant  delays  in  introducing
proposed  products  into  certain  markets  and/or  reduced  sales  of  proposed  products  in  such  markets.  Furthermore,  current  and  future  collaborators  may  act  deliberately  or
inadvertently in ways detrimental to our interests.

The termination of third-party licenses could adversely affect our rights to important compounds or technologies.

We have exercised our option to license Validive; as such, Onxeo has the ability to terminate the license if we breach our obligations under the license agreement. A
termination  of  the  license  agreement  might  force  us  to  cease  developing  and/or  selling  Validive,  if  it  gets  to  market.  We  rely  on  certain  rights  to  MNPR-101  that  we  have
secured  through  a  non-exclusive  license  agreement  with  XOMA.  XOMA,  as  licensor,  has  the  ability  to  terminate  the  license  if  we  breach  our  obligations  under  the  license
agreement and do not remedy any such breach within a set time after receiving written notice of such breach from XOMA. A termination of the license agreement might force
us to cease developing and/or selling MNPR-101-Zr or MNPR-101 RIT, if it gets to market.

Data provided by collaborators and other parties upon which we rely have not been independently verified and could turn out to be inaccurate, misleading, or incomplete.

We  rely  on  third-party  vendors,  scientists,  and  collaborators  to  provide  us  with  significant  data  and  other  information  related  to  our  projects,  clinical  trials,  and
business.  We  do  not  independently  verify  or  audit  all  of  such  data  (including  possibly  material  portions  thereof). As  a  result,  such  data  may  be  inaccurate,  misleading,  or
incomplete.

In certain cases, we may need to rely on a single supplier for a particular manufacturing material or service, and any interruption in or termination of service by such
supplier could delay or disrupt the commercialization of our products.

We rely on third-party suppliers for the materials used to manufacture our compounds. Some of these materials may at times only be available from one supplier. Any
interruption in or termination of service by such single source suppliers could result in a delay or disruption in manufacturing until we locate an alternative source of supply.
There can be no assurance that we would be successful in locating an alternative source of supply or in negotiating acceptable terms with such prospective supplier.

Our  Validive  manufacturer  is  in  the  United  Kingdom  (“UK”),  and  it  is  unknown  in  the  long-term  how  they  will  be  impacted  by  Brexit;  however,  if  they  are  negatively
impacted, this could increase our manufacturing costs, delivery schedules, and adversely impact our financial condition.

The  UK  left  the  European  Union  (“EU”)  on  January  31,  2020,  which  is  commonly  referred  to  as  “Brexit.”  The  full  long-term  impact  of  Brexit,  however,  remains
uncertain. Our Validive manufacturer may be negatively affected by interest rate, exchange rate and other market and economic volatility, as well as regulatory and political
uncertainty. The tax consequences of the UK’s withdrawal from the EU are uncertain as well. If Brexit has a detrimental effect on our Validive manufacturer, it could, in turn,
adversely impact our manufacturing costs and financial condition.

We rely on a limited number of contracted manufacturing plants. If we need to enlist new contract manufacturers, it will delay our camsirubicin clinical program and may
increase our cost for our Phase 1b and future camsirubicin clinical trials.

Our contracted camsirubicin active pharmaceutical ingredient manufacturing plant and our contracted raw materials manufacturing plant are in countries in Asia and
Europe, either of which may be affected by imposed tariffs and regional geopolitical factors outside of their control, including the Russia-Ukraine war, which may affect the
supply of camsirubicin active pharmaceutical ingredient and raw materials. If we need to enlist new contract manufacturers, it will delay our camsirubicin clinical program and
may increase our cost for our Phase 1b and future camsirubicin clinical trials.

We  rely  on  third  parties  to  conduct  our  non-clinical  studies  and  our  clinical  trials.  If  these  third  parties  do  not  successfully  carry  out  their  contractual  duties  or  meet
expected deadlines, we may be unable to obtain regulatory approval for or commercialize our current product candidates or any future products, on a timely and efficient
basis or at all, and our financial condition will be adversely affected.

We  do  not  have  the  capacity  to  independently  conduct  non-clinical  studies  and  clinical  trials.  We  rely  on  medical  institutions,  clinical  investigators,  contract
laboratories, collaborative partners and other third parties, such as contract research organizations or clinical research organizations, to conduct non-clinical studies and clinical
trials on our product candidates. The third parties with whom we contract for execution of our non-clinical studies and clinical trials play a significant role in the conduct of
these studies and trials and the subsequent collection and analysis of data. However, these third parties are not our employees, and except for contractual duties and obligations,
we have limited ability to control the amount or timing of resources that they devote to our programs.

Although we rely on third parties to conduct our non-clinical studies and clinical trials, we remain responsible for ensuring that each of our non-clinical studies and
clinical trials is conducted in accordance with its investigational plan and protocol. Moreover, the FDA, EMA and other foreign regulatory authorities require us to comply with
regulations and standards, including some regulations commonly referred to as good clinical practices (“GCPs”), for conducting, monitoring, recording and reporting the results
of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the trial subjects are adequately informed of the potential risks of participating
in clinical trials.

41

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In addition, the execution of non-clinical studies and clinical trials, and the subsequent compilation and analyses of the data produced, requires coordination among
various  parties.  In  order  for  these  functions  to  be  carried  out  effectively  and  efficiently,  it  is  imperative  that  these  parties  communicate  and  coordinate  with  one  another.
Moreover, these third parties may also have relationships with other commercial entities, some of which may compete with us. Under certain circumstances, these third parties
may be able to terminate their agreements with us upon short notice. If the third parties conducting our clinical trials do not perform their contractual duties or obligations,
experience work stoppages, do not meet expected deadlines, terminate their agreements with us or need to be replaced, or if the quality or accuracy of the clinical data they
obtain is compromised due to the failure to adhere to our clinical trial protocols or GCPs, or for any other reason, we may need to enter into new arrangements with alternative
third parties, which could be difficult, costly or impossible, and our clinical trials may be extended, delayed or terminated or may need to be repeated. If any of the foregoing
were to occur, we may not be able to obtain, on a timely and efficient basis or at all, regulatory approval for or to commercialize the product candidate being tested in such trials,
and as a result, our financial condition will be adversely affected.

Risks Related to Commercialization of Our Product Candidates

We have no experience as a company in commercializing any product. If we fail to obtain commercial expertise, upon product approval by regulatory agencies, our product
launch and revenues could be delayed.

As  a  company,  we  have  never  obtained  regulatory  approval  for,  or  commercialized,  any  product. Accordingly,  we  have  not  yet  begun  to  build  out  any  sales  or
marketing or distribution capabilities. If we are unable to establish, or contract for, effective sales and marketing and distribution capabilities, or if we are unable to enter into
agreements with third parties to commercialize our product candidates on favorable terms or on any reasonable terms at all, we may not be able to effectively generate product
revenues  once  our  product  candidates  are  approved  for  marketing.  If  we  fail  to  obtain  commercial  expertise  or  capabilities,  upon  drug  approval,  our  product  launch  and
subsequent revenues could be delayed and /or fail to reach their commercial potential.

Our product development efforts are at an early stage. We have not yet undertaken any marketing efforts, and there can be no assurance that future anticipated market
testing  and  analyses  will  validate  our  marketing  strategy.  We  may  need  to  modify  the  products,  or  we  may  not  be  successful  in  either  developing  or  marketing  those
products.

As a company, we have not completed the development or clinical trials of any product candidates and, accordingly, have not yet begun to market or generate revenue
from  the  commercialization  of  any  products.  Obtaining  approvals  of  these  product  candidates  will  require  substantial  additional  research  and  development  as  well  as  costly
clinical trials. There can be no assurance that we will successfully complete development of our product candidates or successfully market them. We may encounter problems
and delays relating to research and development, regulatory approval, intellectual property rights of product candidates, or other factors. There can be no assurance that our
development programs will be successful, that our product candidates will prove to be safe and effective in or after clinical trials, that the necessary regulatory approvals for any
product  candidates  will  be  obtained,  or,  even  if  obtained,  will  be  as  broad  as  sought  or  will  be  maintained  for  any  period  thereafter,  that  patents  will  issue  on  our  patent
applications, that any intellectual property protections we secure will be adequate, or that our collaboration arrangements will not diminish the value of our intellectual property
through licensing or other arrangements. Furthermore, there can be no assurance that any product we might market will be received favorably by customers (whether physicians,
payers,  patients,  or  all  three),  adequately  reimbursed  by  third-party  payers,  or  that  competitive  products  will  not  perform  better  and/or  be  marketed  more  successfully.
Additionally, there can be no assurances that any future market testing and analyses will validate our marketing strategies. We may need to seek to modify the product labels
through additional studies in order to be able to market them successfully to reach their commercial potential.

If we are unable to establish relationships with licensees or collaborators to carry out sales, marketing, and distribution functions or to create effective marketing, sales, and
distribution capabilities, we will be unable to market our products successfully.

Our  business  strategy  may  include  out-licensing  product  candidates  to  or  collaborating  with  larger  firms  with  experience  in  marketing  and  selling  pharmaceutical
products. There can be no assurance that we will successfully be able to establish marketing, sales, or distribution relationships with any third-party, that such relationships, if
established, will be successful, or that we will be successful in gaining market acceptance for any products we might develop. To the extent that we enter into any marketing,
sales, or distribution arrangements with third parties, our product revenues per unit sold are expected to be lower than if we marketed, sold, and distributed our products directly,
and any revenues we receive will depend upon the efforts of such third parties.

42

 
 
 
 
 
 
 
 
 
 
Table of Contents

If  we  are  unable  to  establish  such  third-party  marketing  and  sales  relationships,  or  choose  not  to  do  so,  we  would  have  to  establish  in-house  marketing  and  sales
capabilities.  We  have  no  experience  in  marketing  or  selling  oncology  pharmaceutical  products,  and  currently  have  no  marketing,  sales,  or  distribution  infrastructure  and  no
experience developing or managing such infrastructure for an oncology related product. To market any products directly, we would have to establish a marketing, sales, and
distribution force that has technical expertise and could support a distribution capability. Competition in the biopharmaceutical industry for technically proficient marketing,
sales, and distribution personnel is intense and attracting and retaining such personnel may significantly increase our costs. There can be no assurance that we will be able to
establish internal marketing, sales, or distribution capabilities or that these capabilities will be sufficient to meet our needs.

Commercial success of our product candidates will depend on the acceptance of these products by physicians, payers, and patients.

Any product candidate that we may develop may not gain market acceptance among physicians, payers and patients. Market acceptance of and demand for any product

that we may develop will depend on many factors, including without limitation:

●

●

●

●

●

●

●

●

Comparative superiority of the efficacy and safety in the treatment of the disease indication compared to alternative treatments;

Less incidence, less prevalence and more severity of adverse side effects;

Potential advantages over alternative treatments;

Cost effectiveness;

Convenience and ease of administration, stability and shelf life, for distributor, physician and patient;

Sufficient third-party coverage and/or reimbursement;

Strength of sales, marketing and distribution support; and

Our ability to provide acceptable and compelling evidence of safety and efficacy.

If any product candidate developed by us receives regulatory approval but does not achieve an adequate level of market acceptance by physicians, payers, and patients,
we  may  generate  insufficient,  little,  or  no  product  revenue  to  earn  appropriate  returns  on  the  investment  of  product  development  costs  and  may  not  become  profitable  at
sufficient product sales volumes to earn sustainable profitability.

Our products may not be accepted for reimbursement or adequately reimbursed by third-party payers.

The  successful  commercialization  of  any  products  we  might  develop  will  depend  substantially  on  whether  the  costs  of  our  products  and  related  treatments  are
reimbursed at acceptable levels by government authorities, private healthcare insurers, and other third-party payers, such as health maintenance organizations. Reimbursement
rates may vary, depending upon the third-party payer, the type of insurance plan, and other similar or dissimilar factors. If our products do not achieve adequate reimbursement,
then the number of physician prescriptions of our products may not be sufficient to make our products profitable, and to earn a sufficient profit to earn a reasonable return on
our investment and a provide a cash flow to finance future investments on the next generation of products and investments in new technological platforms.

Comparative effectiveness research demonstrating benefits of a competitor’s product could adversely affect the sales of our product candidates. If third-party payers do
not consider our products to be cost-effective compared to other available therapies, they may not cover our products as a benefit under their plans or, if they do, the level of
payment may not be sufficient to allow us to sell our products on a profitable basis sufficient for our Company to remain competitive and thrive.

Table of Contents

Adequate  third-party  reimbursement  may  not  be  available  to  enable  us  to  maintain  price  levels  sufficient  to  realize  an  appropriate  return  on  our  investment  in  the
product development of that product. In addition, in the U.S. there is a growing emphasis on comparative effectiveness research, both by private payers and by government
agencies. To the extent other drugs or therapies are found to be more effective than our products, payers may elect to cover such therapies in lieu of our products or reimburse
our products at a lower rate.

The effects of economic and political pressure to lower pharmaceutical prices are a major threat to the economic viability of new research-based pharmaceutical products,
and any significant decrease in drug prices could materially and adversely affect our prospects.

Emphasis on managed care and government price controls in the U.S. has increased and we expect this will continue to increase the pressure on pharmaceutical pricing.
Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for
which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Any  development  along  these  lines  could  materially  and  adversely  affect  our  prospects.  We  are  unable  to  predict  what  political,  legislative  or  regulatory  changes
relating to the healthcare industry, including without limitation any changes affecting governmental and/or private or third-party coverage and reimbursement, may be enacted
in the future, or what effect such legislative or regulatory changes would have on our business. However, if governmental price management does not provide for the very high
price of pharmaceutical research, it could create very demanding challenges for our industry and our prospects or require breakthroughs in research productivity, of which there
can be no assurance.

If we obtain FDA approval for any of our product candidates, we will be subject to various federal and state fraud and abuse laws; these laws may impact, among other
things,  our  proposed  sales,  marketing  and  education  programs.  Fraud  and  abuse  laws  are  expected  to  increase  in  breadth  and  in  detail,  which  will  likely  increase  our
operating costs and the complexity of our programs to ensure compliance with such enhanced laws.

If  we  obtain  FDA  approval  for  any  of  our  product  candidates  and  begin  commercializing  those  products  in  the  U.S.,  our  operations  may  be  directly,  or  indirectly
through our customers, distributors, or other business partners, subject to various federal and state fraud and abuse laws, including, without limitation, anti-kickback statutes and
false claims statutes which may increase our operating costs. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition,
we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct business.

If our operations are found to be in violation of any of the federal and state fraud and abuse laws or any other governmental regulations that apply to us, we may be subject
to criminal actions and significant civil monetary penalties, which would adversely affect our ability to operate our business and our results of operations.

If  our  operations  are  found  to  be  in  violation,  even  inadvertently,  of  any  of  the  federal  and  state  fraud  and  abuse  laws,  including,  without  limitation,  anti-kickback
statutes  and  false  claims  statutes  or  any  other  governmental  regulations  that  apply  to  us,  we  may  be  subject  to  penalties,  including  criminal  and  significant  civil  monetary
penalties, damages, fines, imprisonment, exclusion from participation in government healthcare programs, and the curtailment or restructuring of our operations, any of which
could adversely affect our ability to operate our business and our results of operations. To the extent that any of our product candidates are ultimately sold in a foreign country,
we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud
and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.

Negotiated prices for our products covered by a Part D prescription drug plan and other government programs will be lower than the prices we might otherwise obtain.

Government  payment  for  some  of  the  costs  of  prescription  drugs  may  increase  demand  for  our  products  for  which  we  receive  marketing  approval;  however,  any
negotiated prices for our products covered by a Part D prescription drug plan and other government programs will be lower than the prices we might otherwise obtain. We
anticipate that the number and type of products that will be subject to federal pricing will increase substantially over time. There may be rules to demand that the government
and medical institutions, which are in part supported by government funding, will be granted access to medicines at the same highly favorable prices given to the governmental
direct medical care programs.

Risks Related to Our Intellectual Property

If we and our third-party licensors do not obtain and preserve protection for our respective intellectual property rights, our competitors may be able to take advantage of
our (and our licensors’) development efforts to develop competing drugs.

Our commercial success will depend in part on obtaining patent protection for any products and other technologies we might develop, and successfully defending any
patents we obtain against third-party challenges. We have licensed all intellectual property related to Validive from Onxeo S.A., a French public company. See “Business –
License,  Development  and  Collaboration  Agreements”.  The  assignment  and  transfer  of  the  camsirubicin  (formerly  GPX-150)  patent  portfolio  from  TacticGem,  LLC
(“TacticGem”) to us has been completed. We filed and have been granted in the U.S. and various countries around the world patents for antibodies that target uPAR for our
MNPR-101  program.  We  have  also  been  granted  in  the  U.S.  and  various  countries  around  the  world  patents  to  a  specific  sequence  of  amino  acids  on  uPAR,  to  which  our
MNPR-101 antibody binds. We are currently prosecuting this patent in other countries around the world to further protect MNPR-101. We also have jointly applied for patents
with our collaborator, NorthStar, for MNPR-101-Zr and MNPR-101 RIT conjugates. The patent process is subject to numerous risks and uncertainties, and there can be no
assurance that we will be successful in obtaining and defending patents. See “Business - Intellectual Property Portfolio and Exclusivity”. These risks and uncertainties include
without limitation the following:

●

●

●

●

●

Patents that may be issued or licensed may be challenged, invalidated, or circumvented; or may not provide any competitive advantage for other reasons.

Our licensors may terminate or breach our existing or future license agreements, thereby reducing or preventing our ability to exclude competition; termination of
such license agreements may also subject us to risk of patent infringement of patents to which we no longer have a license.

Our competitors, many of which have substantially greater resources than us and have made significant investments in competing technologies, may seek, or may
already have obtained, patents that will limit, interfere with, or eliminate our ability to make, use, and sell our potential products either in the U.S. or in
international markets.

As a matter of public policy regarding worldwide health concerns, there may be significant pressure on the U.S. government and other international governmental
bodies to limit the scope of domestic and international patent protection for cancer treatments that prove successful.

Countries other than the U.S. may have less restrictive patent laws than those upheld by the U.S. courts; therefore, non-U.S. competitors could exploit these laws
to create, develop, and market competing products. In some countries, the legal compliance with pharmaceutical patents, patent applications and other intellectual
property regulations is very weak or actively evaded in some cases with government aid.

In  addition,  the  U.S.  Patent  and  Trademark  Office  (“USPTO”)  and  patent  offices  in  other  jurisdictions  have  often  required  that  patent  applications  concerning
pharmaceutical and/or biotechnology-related inventions be limited or narrowed substantially to cover only the specific innovations exemplified in the patent application, thereby
limiting  their  scope  of  protection  against  competitive  challenges.  Thus,  even  if  we  or  our  licensors  are  able  to  obtain  patents,  the  scope  of  the  patents  may  be  substantially
narrower than anticipated.

If we permit our patents to lapse or expire, we will not be protected and will have less of a competitive advantage. The value of our products may be greatly reduced if
this occurs. Our patents expire at different times and are subject to the laws of multiple countries. Some of our patents are currently near expiration and we may pursue patent
term extensions for these where appropriate. See “Business - Intellectual Property Portfolio and Exclusivity”.

In addition to patents, we also rely on trade secrets and proprietary know-how. While we take measures to protect this information by entering into confidentiality and
invention  agreements  with  our  employees,  consultants  and  collaborators,  we  cannot  provide  any  assurances  that  these  agreements  will  be  fully  enforceable  and  will  not  be
breached, that we will be able to protect ourselves from the harmful effects of disclosure if they are not fully enforceable or are breached, that any remedy for a breach will
adequately compensate us, that these agreements will achieve their intended aims, or that our trade secrets will not otherwise become known or be independently discovered by
competitors. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In
addition, some courts inside and outside the U.S., are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently
developed  by  a  competitor,  we  would  have  no  right  to  prevent  them  from  using  that  technology  or  information  to  compete  with  us.  If  any  of  our  trade  secrets  were  to  be
disclosed to or independently developed by a competitor, our competitive position would be harmed, and the value of the trade secrets may be greatly reduced.

The patent protection we obtain and preserve for our product candidates may not be sufficient to provide us with any material competitive advantage.

We may be subject to competition despite the existence of intellectual property we license or own. We can give no assurances that our intellectual property claims will
be sufficient to prevent third parties from designing around patents we own or license and developing and commercializing competitive products. The existence of competitive
products that avoid our intellectual property could materially adversely affect our operating results and financial condition. Furthermore, limitations, or perceived limitations, in
our  intellectual  property  may  limit  the  interest  of  third  parties  to  partner,  collaborate  or  otherwise  transact  with  us,  if  third  parties  perceive  a  higher  than  acceptable  risk  to
commercialization of our products or future products. When looking at our Validive patents’ ability to block competition, the protection offered by our patents may be, to some
extent, more limited than the protection provided by patents claiming the composition of matter of entirely new chemical structures previously unknown. If a competitor were
able to successfully design around any method of use and formulation patents we may have now or in the future, it is highly likely that our business and competitive advantage
would be adversely affected.

Patent terms may be inadequate to protect our competitive position on our product candidates for an adequate amount of time. If this occurs, our competitive position,
business, financial condition, results of operations, and prospects would be materially harmed.

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 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  for  a  product  candidate,  we  may  be  open  to  competition  from  competitive  medications,  including  generic  medications.  Given  the
amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such product candidates might expire before or shortly
after  such  product  candidates  are  commercialized. As  a  result,  our  owned  and  licensed  patent  portfolio  may  not  provide  us  with  sufficient  rights  to  exclude  others  from
commercializing product candidates similar or identical to ours.

Depending upon the timing, duration and conditions of any FDA marketing approval of our product candidates, 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  Act  of  1984,  referred  to  as  the  Hatch-Waxman  Amendments,  and  similar
legislation  in  the  European  Union.  The  Hatch-Waxman  Amendments  permit  a  patent  term  extension  of  up  to  five  years  for  a  patent  covering  an  approved  product  as
compensation  for  effective  patent  term  lost  during  product  development  and  the  FDA  regulatory  review  process.  However,  we  may  not  receive  an  extension  if  we  fail  to
exercise due diligence during the testing phase or regulatory review process, fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or
otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. Only one patent per approved product can be extended,
the  extension  cannot  extend  the  total  patent  term  beyond  14  years  from  approval  and  only  those  claims  covering  the  approved  drug,  a  method  for  using  it  or  a  method  for
manufacturing it may be extended. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can
enforce our patent rights for the applicable product candidate will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our
revenue from applicable products could be reduced. Further, if this occurs, our competitors may take advantage of our investment in development and trials by referencing our
clinical and preclinical data and launch their product earlier than might otherwise be the case, and our competitive position, business, financial condition, results of operations,
and prospects would be materially harmed.

Intellectual property disputes could require us to spend time and money to address such disputes and could limit our intellectual property rights.

The biopharmaceutical industry has been characterized by extensive litigation regarding patents and other intellectual property rights, and companies have employed
intellectual property litigation and USPTO post-grant proceedings to gain a competitive advantage. We may become subject to infringement claims or litigation arising out of
patents and pending applications of our competitors, or additional interference proceedings declared by the USPTO to determine the priority and patentability of inventions. The
defense and prosecution of intellectual property suits, USPTO proceedings, and related legal and administrative proceedings are costly and time-consuming to pursue, and their
outcome  is  uncertain.  Litigation  may  be  necessary  to  enforce  our  issued  patents,  to  protect  our  trade  secrets  and  know-how,  or  to  determine  the  enforceability,  scope,  and
validity of the proprietary rights of others. An adverse determination in litigation or USPTO post-grant and interference proceedings to which we may become a party could
subject us to significant liabilities, require us to obtain licenses from third parties, or restrict or prevent us from selling our products in certain markets. Even if a given patent or
intellectual  property  dispute  were  settled  through  licensing  or  similar  arrangements,  our  costs  associated  with  such  arrangements  may  be  substantial  and  could  include  the
payment by us of large, fixed payments and ongoing royalties. Furthermore, the necessary licenses may not be available on satisfactory terms or at all. Even where we have
meritorious claims or defenses, the costs of litigation may prevent us from pursuing these claims or defenses and/or may require extensive financial and personnel resources to
pursue these claims or defenses. In addition, it is possible there may be defects of form in our current and future patents that could result in our inability to defend the intended
claims. Intellectual property disputes arising from the aforementioned factors, or other factors, may materially harm our business.

We may not be able to enforce our intellectual property rights throughout the world.

The  laws  of  some  foreign  countries  do  not  protect  intellectual  property  rights  to  the  same  extent  as  the  laws  of  the  U.S.  Companies  have  encountered  significant
problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not
favor the enforcement of patents and other intellectual property protection, especially those relating to life sciences. This could make it difficult for us to stop the infringement of
our patents or the misappropriation of our other intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner
must  grant  licenses  to  third  parties.  In  addition,  many  countries  limit  the  enforceability  of  patents  against  third  parties,  including  government  agencies  or  government
contractors. In these countries, patents may provide limited or no benefit.

Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from
other aspects of our business. Furthermore, while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able
to initiate or maintain similar efforts in all jurisdictions in which we may wish to market Validive or any future products. Accordingly, our efforts to protect our intellectual
property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the U.S. and foreign countries may affect our ability to
obtain and enforce adequate intellectual property protection for our products and technology.

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

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents
in the biopharmaceutical industry involves both technological and legal diligence and complexity. Therefore, obtaining and enforcing biopharmaceutical patents is costly, time
consuming and inherently uncertain. In addition, the U.S. has recently enacted and is currently implementing wide ranging patent reform legislation. The U.S. Supreme Court
has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in
certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to
the value of patents once obtained. Depending on future actions by the U.S. Congress, the federal courts and the USPTO, as well as other jurisdictions around the world, the
laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents
that we might obtain in the future.

Table of Contents

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.

The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during
the patent process. There are situations in which noncompliance due to issues beyond our control, can result in abandonment or lapse of a patent or patent application, resulting
in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the
case.

If we fail to comply with our obligations under any license, collaboration or other intellectual property-related agreements, we may be required to pay damages and could
lose intellectual property rights that may be necessary for developing, commercializing and protecting our current or future technologies or drug candidates or we could
lose certain rights to grant sublicenses.

Any  license,  collaboration  or  other  intellectual  property-related  agreements  impose,  and  any  future  license,  collaboration  or  other  intellectual  property-related
agreements we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and
enforcement or other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to
pay  damages  and  the  licensor  may  have  the  right  to  terminate  the  license.  In  spite  of  our  best  efforts,  any  of  our  future  licensors  might  conclude  that  we  have  materially
breached our license agreements and might therefore terminate the license agreements, thereby removing our ability to develop and commercialize products and technologies
covered  by  these  license  agreements. Any  license  agreements  we  enter  into  may  be  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 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.

We may seek to obtain licenses from licensors in the future, however, we may be unable to obtain any such licenses at a reasonable cost or on reasonable terms, if at all.
In addition, if any of our future licensors terminate any such license agreements, such license termination could result in our inability to develop, manufacture and sell products
that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Any of these events could have a material adverse effect on
our competitive position, business, financial condition, results of operations, and ability to achieve profitability.

Furthermore, we may not have the right to control the preparation, filing, prosecution, maintenance, enforcement and defense of patents and patent applications that we
license from third parties. Therefore, we cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced and defended in a
manner  consistent  with  the  best  interests  of  our  business.  If  our  future  licensors  fail  to  prosecute,  maintain,  enforce  and  defend  patents  we  may  in-license,  or  lose  rights  to
licensed patents or patent applications, our license rights may be reduced or eliminated. In such circumstances, our right to develop and commercialize any of our products or
drug  candidates  that  is  the  subject  of  such  licensed  rights  could  be  materially  adversely  affected.  In  certain  circumstances,  our  licensed  patent  rights  are  subject  to  our
reimbursing our licensors for their patent prosecution and maintenance costs.

Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit,
that we are infringing, misappropriating or otherwise violating the licensor’s intellectual property rights and the amount of any damages or future royalty obligations that would
result, if any such claims were successful, would depend on the technology and intellectual property we use in products that we successfully develop and commercialize, if any.
Therefore, even if we successfully develop and commercialize products, due to such obligations, we may be unable to achieve or maintain profitability.

Third parties may initiate legal proceedings alleging that we are infringing, misappropriating or otherwise violating their intellectual property rights, the outcome of which
would be uncertain and could have a material adverse impact on the success of our business.

Our commercial success depends, in part, upon our ability or the ability of any of our future collaborators to develop, manufacture, market and sell our current or any
future drug candidates and to use our proprietary technologies without infringing, misappropriating or otherwise violating the proprietary and intellectual property rights of third
parties. The biotechnology and pharmaceutical industries are characterized by extensive and complex litigation regarding patents and other intellectual property rights.

We or any of our future licensors or strategic partners, may be party to, or be threatened with, adversarial proceedings or litigation regarding intellectual property rights
with respect to our current or any potential future drug candidates and technologies, including derivation, reexamination, inter partes review, post-grant review or interference
proceedings  before  the  USPTO  and  similar  proceedings  in  jurisdictions  outside  of  the  U.S.  such  as  opposition  proceedings.  If  we  or  our  licensors  or  strategic  partners  are
unsuccessful  in  any  interference  proceedings  or  other  priority  or  validity  disputes  (including  through  any  patent  oppositions)  to  which  we  or  they  are  subject,  we  may  lose
valuable intellectual property rights through the loss of one or more patents or our patent claims may be narrowed, invalidated, or held unenforceable. In some instances, we
may  be  required  to  indemnify  our  licensors  or  strategic  partners  for  the  costs  associated  with  any  such  adversarial  proceedings  or  litigation.  Third  parties  may  also  assert
infringement, misappropriation or other claims against us, our licensors or our strategic partners based on existing patents or patents that may be granted in the future, as well as
other intellectual property rights, regardless of their merit. There is a risk that third parties may choose to engage in litigation or other adversarial proceedings with us, our
licensors or our strategic partners to enforce or otherwise assert their patent rights or other intellectual property rights. Even if we believe such claims are without merit, a court
of competent jurisdiction could hold that these third-party patents and other intellectual property rights are valid, enforceable and infringed, which could have a material adverse
impact  on  our  ability  to  utilize  our  developed  technologies  or  to  commercialize  our  current  or  any  future  drug  candidates  deemed  to  be  infringing.  In  order  to  successfully
challenge the validity of any such U.S. patent in federal court, we would need to overcome a presumption of validity by presenting clear and convincing evidence of invalidity.
There is no assurance that a court of competent jurisdiction, even if presented with evidence we believe to be clear and convincing, would invalidate the claims of any such U.S.
patent.

Further, we cannot guarantee that we will be able to successfully settle or otherwise resolve such adversarial proceedings or litigation. If we are unable to successfully
settle future claims on terms acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from or
experience substantial delays in marketing our drug candidates. If we or any of our licensors or strategic partners are found to infringe, misappropriate or violate a third-party
patent or other intellectual property rights, we could be required to pay damages, including treble damages and attorney’s fees, if we are found to have willfully infringed. In
addition, we, or any of our licensors or strategic partners may choose to seek, or be required to seek, a license from a third-party, which may not be available on commercially
reasonable terms, if at all. Even if a license can be obtained on commercially reasonable terms, the rights may be non-exclusive, which could give our competitors access to the
same technology or intellectual property rights licensed to us, and we could be required to make substantial licensing and royalty payments. We also could be forced, including
by court order, to cease utilizing, developing, manufacturing and commercializing our developed technologies or drug candidates deemed to be infringing. We may be forced to
redesign current or future technologies or products. Any of the foregoing could have a material adverse effect on our ability to generate revenue or achieve profitability and
possibly prevent us from generating revenue sufficient to sustain our operations.

In addition, we or our licensors or strategic partners may find it necessary to pursue claims or to initiate lawsuits to protect or enforce our patent or other intellectual
property rights. If we or our licensors or strategic partners were to initiate legal proceedings against a third-party to enforce a patent covering one of our drug candidates or our
developed technology, the defendant could counterclaim that such patent is invalid or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity
or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, claiming patent-
ineligible  subject  matter,  lack  of  novelty,  indefiniteness,  lack  of  written  description,  non-enablement,  anticipation  or  obviousness.  Grounds  for  an  unenforceability  assertion
could  be  an  allegation  that  someone  connected  with  prosecution  of  the  patent  withheld  relevant  information  from  the  USPTO  or  made  a  misleading  statement  during
prosecution. The outcome of such invalidity and unenforceability claims is unpredictable. With respect to the validity question, for example, we cannot be certain that there is
no invalidating prior art of which we or our licensors or strategic partners and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal
assertion of invalidity or unenforceability, we could lose at least part, and perhaps all, of the patent protection for one or more of our drug candidates. The narrowing or loss of
our owned and licensed patent claims could limit our ability to stop others from using or commercializing similar or identical technologies and products. All of these events
could have a material adverse effect on our business, financial condition, results of operations and prospects. Patent and other intellectual property rights also will not protect
our  drug  candidates  and  technologies  if  competitors  or  third  parties  design  around  such  drug  candidates  and  technologies  without  legally  infringing,  misappropriating  or
violating our patent or other intellectual property rights.

The cost to us in defending or initiating any litigation or other proceedings relating to our patent or other intellectual property rights, even if resolved in our favor, could
be substantial, and any litigation or other proceedings would divert our management’s attention and distract our personnel from their normal responsibilities. Such litigation or
proceedings could materially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities.
We may not have sufficient financial or other resources to conduct such litigation or proceedings adequately. Some of our competitors may be able to more effectively sustain
the costs of complex patent litigation because they have substantially greater resources. Uncertainties resulting from the initiation and continuation of patent litigation or other
proceedings could delay our research and development efforts and materially limit our ability to continue our operations. Furthermore, because of the substantial amount of
discovery required in connection with certain such proceedings, there is a risk that some of our confidential information could be compromised by disclosure. 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, such announcements could have a material adverse effect on the price of our common stock.

Intellectual  property  rights  of  third  parties  could  adversely  affect  our  ability  to  commercialize  our  current  or  future  technologies  or  drug  candidates,  and  we  might  be
required  to  litigate  or  obtain  licenses  from  third  parties  to  develop  or  market  our  current  or  future  technologies  or  drug  candidates,  which  may  not  be  available  on
commercially reasonable terms, or at all.

There  are  numerous  companies  that  have  pending  patent  applications  and  issued  patents  broadly  covering  immune-therapies  generally  or  covering  small  molecules
directed against the same targets as, or targets similar to, those we are pursuing. Our competitive position may materially suffer if patents issued to third parties or other third-
party intellectual property rights cover our current or future technologies, drug candidates or elements thereof, or our manufacture or uses relevant to our development plans. In
such cases, we may not be in a position to develop or commercialize current or future technologies or drug candidates unless we successfully pursue litigation to nullify or
invalidate  the  third-party  intellectual  property  rights  concerned  or  enter  into  a  license  agreement  with  the  intellectual  property  rights  holder,  if  available  on  commercially
reasonable terms. There may be issued patents of which we are not aware, held by third parties that, if found to be valid and enforceable, could be alleged to be infringed by our
current or future technologies or drug candidates. There also may be pending patent applications of which we are not aware that may result in issued patents, which could be
alleged  to  be  infringed  by  our  current  or  future  technologies  or  drug  candidates.  Should  such  an  infringement  claim  be  successfully  brought,  we  may  be  required  to  pay
substantial damages or be forced to abandon our current or future technologies or drug candidates or to seek a license from any patent holders. No assurances can be given that a
license will be available on commercially reasonable terms, if at all.

Third-party intellectual property rights holders may also actively bring infringement, misappropriation or other claims alleging violations of intellectual property rights
against  us.  We  cannot  guarantee  that  we  will  be  able  to  successfully  settle  or  otherwise  resolve  such  claims.  If  we  are  unable  to  successfully  settle  future  claims  on  terms
acceptable to us, we may be required to engage in or to continue costly, unpredictable and time-consuming litigation and may be prevented from, or experience substantial
delays in, marketing our drug candidates. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from
commercializing  any  of  our  current  or  future  technologies  or  drug  candidates  that  are  held  to  be  infringing,  misappropriating  or  otherwise  violating  third-party  intellectual
property rights. We might, if possible, also be forced to redesign current or future technologies or drug candidates so that we no longer infringe, misappropriate or violate the
third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that
we would otherwise be able to devote to our business, which could have a material adverse effect on our financial condition and results of operations.

Risks Related to Our Business Operations and Industry

We have a limited operating history.

To date, we have engaged exclusively in acquiring pharmaceutical product candidates, licensing rights to product candidates, entering into collaboration agreements
with  respect  to  key  services  or  technologies  for  our  drug  product  development,  and  commenced  clinical  trials,  but  have  not  yet  completed  any  clinical  trials,  received  any
governmental approvals, brought any product to market, manufactured products in commercial quantities or sold any pharmaceutical products. As a company we have limited
experience in negotiating, establishing, and maintaining strategic relationships, conducting clinical trials, and managing the regulatory approval process, all of which will be
necessary if we are to be successful. Our lack of experience in these critical areas makes it difficult for a prospective investor to evaluate our abilities and increases the risk that
we will fail to successfully execute our strategies.

50

 
 
 
 
 
 
 
 
 
Table of Contents

Furthermore,  if  our  business  grows  rapidly,  our  operational,  managerial,  legal,  and  financial  resources  will  be  strained.  Our  development  will  require  continued

improvement and expansion of our management team and our operational, managerial, legal, and financial systems and controls.

In  the  normal  course  of  business,  we  have  evaluated  and  expect  to  evaluate  potential  acquisitions  and/or  licenses  of  patents,  compounds,  and  technologies  that  our
management believes could complement or expand our business. In the event that we identify an acquisition or license candidate we find attractive, there is no assurance that we
will be successful in negotiating an agreement to acquire or license, or in financing or profitably exploiting, such patents, compounds, or technologies. Furthermore, such an
acquisition or license could divert management time and resources away from other activities that would further our current business development.

If  we  lose  key  management  leadership,  and/or  scientific  personnel,  and  if  we  cannot  recruit  qualified  employees,  managers,  directors,  officers,  or  other  significant
personnel, it is highly likely that we will experience program delays and increases in compensation costs, and our business will be materially disrupted.

Our  future  success  is  highly  dependent  on  the  continued  service  of  principal  members  of  our  management,  leadership,  and  scientific  personnel,  who  are  able  to
terminate their employment with us at any time and may be able to compete with us. The loss of any of our key management, leadership, or scientific personnel including, in
particular,  Christopher  M.  Starr,  our  Executive  Chairman  of  the  Board  of  Directors  (referred  to  as  the  “Board”),  and  Chandler  D.  Robinson,  our  President  and  CEO,  could
materially disrupt our business and materially delay or prevent the successful product development and commercialization of our product candidates. We have an employment
agreement  with  Dr.  Robinson  which  has  no  term  but  is  for  at-will  employment,  meaning  the  executive  has  the  ability  to  terminate  his  employment  at  any  time.  We  have  a
consulting agreement with Dr. Starr that is terminable with 30-days’ notice by Dr. Starr or us.

Our future success will also depend on our continuing ability to identify, hire, and retain highly skilled personnel for all areas of the organization. Competition in the
biopharmaceutical industry for scientifically and technically qualified personnel is intense, and we may be unsuccessful in identifying, hiring, and retaining qualified personnel.
Our continued requirement to identify, hire, and retain highly competent personnel may cause our compensation costs to increase materially.

We  incur  costs  as  a  result  of  operating  as  a  public  company,  and  our  management  is  required  to  devote  substantial  time  to  investor  relations,  information  and
communication to the public, and related compliance initiatives and corporate governance practices.

As a public company, and particularly after we are no longer an emerging growth company, we will incur significant legal, accounting and other expenses that we did
not incur as a private company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listing requirements of the Nasdaq Capital
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 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. For example, we expect that these rules
and regulations may make it more difficult and more expensive for us to obtain director and officer liability insurance, which in turn could make it more difficult for us to attract
and retain qualified members of our Board. However, 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.

Despite  ongoing  compliance  training  and  periodic  education,  our  employees  and  consultants  may  engage  in  misconduct  or  other  improper  activities,  including
noncompliance with regulatory standards and requirements, which could result in delays or terminations of our development programs and adversely affect our business.

Although we regularly train our employees on compliance and we are aware of no misconduct or improper activities to date, we are exposed to the risk of employee or
consultant  fraud  or  other  misconduct.  Misconduct  by  our  employees  or  consultants  could  include  intentional  failures  to:  comply  with  FDA  regulations;  provide  accurate
information to the FDA; comply with manufacturing standards; comply with federal and state healthcare fraud and abuse laws and regulations; report financial information or
data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and
regulations  intended  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,  sales  commission,  customer  incentive  programs  and  other  business  arrangements.  Employee  and  consultant  misconduct  could  also
involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always
possible to identify and deter such misconduct, 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 be in compliance with such laws or 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  fines  or  other  sanctions.  Such  actions  could  adversely  affect  our  business  including  delaying  or  terminating  one  or  more  of  our
development programs.

We are an emerging growth company and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common
stock less attractive to investors.

We are an emerging growth company. Under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), emerging growth companies can delay adopting new
or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected to opt out of this provision and, as a result, we will
comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies.

For as long as we continue to be an emerging growth company, we also intend to take advantage of certain other exemptions from various reporting requirements that
are  applicable  to  other  public  companies  including,  but  not  limited  to,  reduced  disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports  and  proxy
statements, exemptions from the requirements of holding a nonbinding advisory stockholder vote on executive compensation and any golden parachute payments not previously
approved, exemption from the requirement of auditor attestation in the assessment of our internal control over financial reporting and exemption from any requirement that may
be  adopted  by  the  Public  Company  Accounting  Oversight  Board  regarding  mandatory  audit  firm  rotation  or  a  supplement  to  the  auditor’s  report  providing  additional
information  about  the  audit  and  the  financial  statements  (auditor  discussion  and  analysis).  If  we  do  take  advantage  of  these  exemptions,  the  information  that  we  provide
stockholders will be different than what is available with respect to other public companies. We cannot predict if investors will find our common stock less attractive because
we will rely on these exemptions. If investors find our common stock less attractive as a result of our status as an emerging growth company, there may be less liquidity for our
common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest of (1) the last day of the year (a) following the fifth anniversary of the completion of our initial public
offering, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of
our  common  stock  that  is  held  by  non-affiliates  exceeds  $700  million  as  of  the  prior  June  30th,  and  (2)  the  date  on  which  we  have  issued  more  than  $1.0  billion  in  non-
convertible debt securities during the prior three-year period. We anticipate this will be December 31, 2024.

Competition and technological change may make our product candidates less competitive or obsolete.

The  biopharmaceutical  industry  is  subject  to  rapid  technological  change.  We  have  many  potential  competitors,  including  major  drug  and  chemical  companies,
specialized biopharmaceutical firms, universities and other research institutions. These companies, firms, and other institutions may develop products that are more effective
than  our  product  candidates  or  that  would  make  our  product  candidates  less  competitive  or  obsolete.  Many  of  these  companies,  firms,  and  other  institutions  have  greater
financial resources than us and may be better able to withstand and respond to adverse market conditions within the biopharmaceutical industry, including without limitation the
lengthy product development and regulatory approval processes for product candidates.

We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.

The  biotechnology  and  pharmaceutical  industries  are  characterized  by  rapidly  advancing  technologies,  intense  competition  and  a  strong  emphasis  on  proprietary
products. While we believe we have significant competitive advantages with our expertise in small molecules and biologics, and rare disease clinical development, along with a
strong  intellectual  property  portfolio,  we  currently  face  and  will  continue  to  face  competition  for  our  drug  development  programs  from  companies  that  target  SOM,  are
developing  doxorubicin  analogs/replacement,  or  are  targeting  uPAR.  The  competition  is  likely  to  come  from  multiple  sources,  including  larger  pharmaceutical  companies,
biotechnology  companies  and  academia. Accordingly,  our  competitors  may  have  more  resources  and  be  more  successful  than  us  in  obtaining  approval  for  treatments  and
achieving widespread market acceptance. For any products that we may ultimately commercialize, not only will we compete with any existing therapies and those therapies
currently in development, we will have to compete with new therapies that may become available in the future.

We may engage in strategic transactions that could impact our liquidity, increase our expenses and present significant distractions to our management.

From time to time, we may consider strategic transactions, such as acquisitions of companies, asset purchases, and out-licensing or in-licensing of products, product
candidates  or  technologies.  Additional  potential  transactions  that  we  may  consider  include  a  variety  of  different  business  arrangements,  including  spin-offs,  strategic
partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any such transaction will require us to incur non-recurring or other charges,
may increase our near- and long-term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our
operations and financial results. For example, these transactions may entail numerous operational and financial risks, including:

●

●

●

●

●

●

●

●

●

exposure to unknown technologies, product candidates, medical conditions and indications, product manufacturing challenges and uncertainties, and other
unknown factors of potential high risk;

disruption of our business and diversion of our management’s time and attention in order to develop acquired products, product candidates or technologies;

incurrence of substantial debt or dilutive issuances of equity securities to pay for acquisitions;

higher-than-expected acquisition and integration costs;

write-downs of assets, goodwill or impairment charges;

increased amortization expenses;

difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;

impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and

inability to retain key employees of any acquired businesses or for our current business based on changed circumstances.

Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that
we do complete may be subject to the foregoing or other risks, and could have a material adverse effect on our business, results of operations, financial condition and prospects.

Our business and operations are vulnerable to computer system failures, cyber-attacks or deficiencies in our cyber-security, which could increase our expenses, divert the
attention of our management and key personnel away from our business operations and adversely affect our results of operations.

Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are vulnerable to damage from: computer
viruses; malware; natural disasters; terrorism; war; telecommunication and electrical failures; cyber-attacks or cyber-intrusions over the Internet; attachments to emails; persons
inside  our  organization;  or  persons  with  access  to  systems  inside  our  organization.  The  risk  of  a  security  breach  or  disruption,  particularly  through  cyber-attacks  or  cyber
intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and
intrusions from around the world have increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product
development programs. For example, the loss of clinical trial data from completed or ongoing or planned 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 or security breach was to result in a loss of or damage to our data or
applications, or inappropriate disclosure of confidential or proprietary information, we could incur material legal claims and liability, and damage to our reputation, and the
further development of our product candidates could be delayed. We could be forced to expend significant resources in response to a cyber security breach, including repairing
system damage, increasing cyber security protection costs by deploying additional personnel and protection technologies, paying regulatory fines and resolving legal claims and
regulatory actions, all of which would increase our expenses, divert the attention of our management and key personnel away from our business operations and adversely affect
our results of operations.

Failure to comply with health and data protection laws and regulations could lead to government enforcement actions (which could include civil or criminal penalties),
private litigation or adverse publicity and could negatively affect our operating results and business.

We and our current and any of our future collaborators may be subject to federal, state and foreign data protection laws and regulations (i.e., laws and regulations that
address privacy and data security). In the U.S., numerous federal and state laws and regulations, including federal health information privacy laws (e.g., the Health Insurance
Portability  and Accountability Act  (“HIPAA”),  as  amended  by  the  Health  Information  Technology  for  Economic  and  Clinical  Health Act  (“HITECH”)),  state  data  breach
notification laws, state health information privacy laws and federal and state consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), that govern the
collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of our collaborators. In addition, we
may obtain health information from third parties (including research institutions from which we obtain clinical trial data) that are subject to privacy and security requirements
under HIPAA, as amended by HITECH, or other privacy and data security laws. Depending on the facts and circumstances, we could be subject to criminal penalties if we
knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA.

International data protection laws, including Regulation 2016/679, known as the General Data Protection Regulation (“GDPR”) may also apply to health-related and
other personal information obtained outside of the U.S. The GDPR went into effect on May 25, 2018. The GDPR introduced new data protection requirements in the EU, as
well as potential fines for non-compliant companies of up to the greater of €20 million or 4% of annual global revenue. The regulation imposes numerous new requirements for
the collection, use, storage and disclosure of personal information, including more stringent requirements relating to consent and the information that must be shared with data
subjects  about  how  their  personal  information  is  used,  the  obligation  to  notify  regulators  and  affected  individuals  of  personal  data  breaches,  extensive  new  internal  privacy
governance obligations and obligations to honor expanded rights of individuals in relation to their personal information (e.g., the right to access, correct and delete their data). In
addition, the GDPR includes restrictions on cross-border data transfers. The GDPR increased 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 to ensure compliance with the GDPR, including as implemented by
individual countries. Further Brexit has created uncertainty with regard to data protection regulation in the United Kingdom. In particular, it is unclear how data transfers to and
from the United Kingdom will be regulated.

In  addition,  California  recently  enacted  the  California  Consumer  Privacy Act  (“CCPA”),  which  creates  new  individual  privacy  rights  for  California  consumers  (as
defined  in  the  law)  and  places  increased  privacy  and  security  obligations  on  entities  handling  personal  data  of  consumers  or  households.  The  CCPA  will  require  covered
companies to provide new disclosure to consumers about such companies’ data collection, use and sharing practices, provide such consumers new ways to opt-out of certain
sales or transfers of personal information, and provide consumers with additional causes of action. The CCPA went into effect on January 1, 2020, and the California Attorney
General may bring enforcement actions for violations beginning July 1, 2020. The CCPA was amended on September 23, 2018, and it remains unclear what, if any, further
modifications will be made to this legislation or how it will be interpreted. As currently written, the CCPA may impact our business activities and exemplifies the vulnerability
of our business to the evolving regulatory environment related to personal data and protected health information.

Compliance with U.S. and international data protection laws and regulations could require us to take on more onerous obligations in our contracts, restrict our ability to
collect, use and disclose data, or in some cases, impact our ability to operate in certain jurisdictions. Failure to comply with U.S. and international data protection laws and
regulations could result in government enforcement actions (which could include civil or criminal penalties), private litigation or adverse publicity and could negatively affect
our operating results and business.

If we, our contract research organizations (“CROs”) or our IT vendors experience security or data privacy breaches or other unauthorized or improper access to, use of, or
destruction of personal data, we may face costs, significant liabilities, harm to our brand and business disruption.

In connection with our drug research and development efforts, we or our CROs may collect and use a variety of personal data, such as names, mailing addresses, email
addresses,  phone  numbers  and  clinical  trial  information. Although  we  have  extensive  measures  in  place  to  prevent  the  sharing  and  loss  of  patient  data  in  our  clinical  trial
processes associated with our developed technologies and drug candidates, any failure to prevent or mitigate security breaches or improper access to, use of, or disclosure of our
clinical data or patients’ personal data could result in significant liability under state (e.g., state breach notification laws), federal (e.g., HIPAA, as amended by HITECH), and
international laws (e.g., the GDPR). Any failure to prevent or mitigate security breaches or improper access to, use of, or disclosure of our clinical data or patients’ personal data
may cause a material adverse impact to our reputation, affect our ability to conduct new studies and potentially disrupt our business. We may also rely on third-party IT vendors
to host or otherwise process some of our data and that of users, and any failure by such IT vendor to prevent or mitigate security breaches or improper access to or disclosure of
such information could have similarly adverse consequences for us. If we are unable to prevent or mitigate the impact of such security or data privacy breaches, we could be
exposed to litigation and governmental investigations, which could lead to a potential disruption to our business.

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our  research  and  development  and  drug  candidates  and  future  commercial  manufacturing  may  involve  the  use  of  hazardous  materials  and  various  chemicals.  We
currently  do  not  maintain  a  research  laboratory,  but  we  engage  third-party  research  organizations  and  manufacturers  to  conduct  our  preclinical  studies,  clinical  trials  and
manufacturing. These third-party laboratories and manufacturers are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling
and disposal of these hazardous materials. We must rely on the third parties’ procedures for storing, handling and disposing of these materials in their facilities to comply with
the relevant guidelines of the states in which they operate and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe that
their safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations, the risk of accidental contamination or
injury  from  these  materials  cannot  be  eliminated.  If  an  accident  occurs,  this  could  result  in  significant  delays  in  our  development.  We  are  also  subject  to  numerous
environmental, health and workplace safety laws and regulations. Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due
to injuries to our employees, this insurance may not provide adequate coverage against potential liabilities. Additional federal, state and local laws and regulations affecting our
operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

We have limited the liability of and indemnified our directors and officers.

Although  our  directors  and  officers  are  accountable  to  us  and  must  exercise  good  faith,  good  business  judgement,  and  integrity  in  handling  our  affairs,  our  Second
Amended  and  Restated  Certificate  of  Incorporation  (the  “Certificate  of  Incorporation”)  and  indemnification  agreements  executed  by  all  of  our  non-employee  directors  and
officers provides that our non-employee directors and officers will be indemnified to the fullest extent permitted under Delaware law. As a result, our stockholders may have
fewer rights against our non-employee directors and officers than they would have absent such provisions in our Certificate of Incorporation and indemnification agreements,
and a stockholder’s ability to seek and recover damages for a breach of fiduciary duties may be reduced or restricted. Delaware law allows indemnification of our non-employee
directors and officer, if they (a) have acted in good faith, in a manner the non-employee director or officer reasonably believes to be in or not opposed to our best interests, and
(b) with respect to any criminal action or proceeding, if the non-employee director or officer had no reasonable cause to believe the conduct was unlawful.

55

 
 
 
 
 
 
 
 
 
 
Table of Contents

Pursuant to the Certificate of Incorporation and indemnification agreement, each non-employee director and officer who is made a party to a legal proceeding because
he or she is or was a non-employee director or officer, is indemnified by us from and against any and all liability, except that we may not indemnify a non-employee director or
officer: (a) for any liability incurred in a proceeding in which such person is adjudged liable to Monopar or is subjected to injunctive relief in favor of Monopar; (b) for acts or
omissions that involve intentional misconduct or a knowing violation of law, fraud or gross negligence; (c) for unlawful distributions; (d) for any transaction for which such
non-employee director or officer received a personal benefit or as otherwise prohibited by or as may be disallowed under Delaware law; or (e) with respect to any dispute or
proceeding between us and such non-employee director or officer unless such indemnification has been approved by a disinterested majority of the Board or by a majority in
interest of disinterested stockholders. We are required to pay or reimburse attorney’s fees and expenses of a non-employee director or officer seeking indemnification as they
are incurred, provided the non-employee director or officer executes an agreement to repay the amount to be paid or reimbursed if there is a final determination by a court of
competent jurisdiction that such person is not entitled to indemnification.

Future legislation or executive or private sector actions may increase the difficulty and cost for us to commercialize our products and adversely affect the prices obtained
for such products.

In the U.S., there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the Affordable Care Act (the
“ACA”),  was  enacted,  which  substantially  changed  the  way  healthcare  is  financed  by  both  governmental  and  private  insurers,  and  significantly  impacted  the  U.S.
pharmaceutical industry.

Since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the ACA, and we expect there will be
additional challenges and amendments to the ACA in the future. Various portions of the ACA are currently undergoing legal and constitutional challenges in the US Supreme
Court; the Trump Administration signed various executive orders and other directives that eliminated cost sharing subsidies and various provisions that would impose a fiscal
burden on states or a cost, fee, tax, penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices;
and Congress has introduced several pieces of legislation aimed at significantly revising or repealing the ACA. The US Supreme Court is expected to rule on a legal challenge
to the constitutionality of the ACA in 2021. The American Rescue Plan Act of 2021 which was recently enacted into law includes provisions which further the ACA, including
expansion of marketplace subsidies and credits to reduce or eliminate premiums in the federal exchange for persons with certain income levels and providing subsidies for state
exchanges. The implementation of the ACA is ongoing, the law appears likely to continue the downward pressure on pharmaceutical pricing, especially under the Medicare
program, and may also increase regulatory burdens and operating costs. Litigation and legislation related to the ACA are likely to continue, with unpredictable and uncertain
results. It is unclear whether the ACA will be overturned, repealed, replaced, or further amended. We cannot predict what affect further changes to the ACA would have on our
business.

In addition, government price reporting and payment regulations are complex, and we will be required to continually assess the methods by which we plan to calculate
and report any future pricing in accordance with these obligations. Our methodologies for calculations are inherently subjective and may be subject to review and challenge by
various government agencies, which may disagree with our interpretation. If the government disagrees with our reported calculations, we may need to restate the previously
reported data and could be subject to additional financial and legal liability.

Further, the increasing cost of healthcare as a percentage of GDP and the massive and increasing deferred liabilities behind most governmental healthcare programs
(such as Medicare and Medicaid and state and local healthcare programs especially for retirement benefits) continue to be an economic challenge which threatens the overall
economic health of the U.S. High cost healthcare products and therapies that are early in their life cycle are attractive targets for parties that believe that the cost of healthcare
must  be  better  controlled  and  significantly  reduced.  Pharmaceutical  prices  and  healthcare  reform  have  been  debated  and  acted  upon  by  legislators  for  many  years.  Future
legislation or executive or private sector actions related to healthcare reform could materially and adversely affect our business by reducing our ability to generate revenue at
prices sufficient to reward for the risks and costs of pharmaceutical development, to raise capital, and to market our products.

There is no assurance that federal or state healthcare reform will not adversely affect our future business and financial results, and we cannot predict how future federal
or state legislative, judicial or administrative changes relating to healthcare reform and third-party payers will affect the pharmaceutical industry in general and our business in
particular.

Even  if  we  are  able  to  commercialize  any  drug  candidate,  such  drug  candidate  may  become  subject  to  unfavorable  pricing  regulations  or  third-party  coverage  and
reimbursement policies, which would harm our business.

Our ability to commercialize any products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for these products and related
treatments  will  be  available  from  third-party  payors,  such  as  government  authorities,  private  healthcare  insurers  and  health  maintenance  organizations.  Patients  who  are
prescribed medications for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs.
Coverage  and  adequate  reimbursement  from  government  healthcare  programs,  such  as  Medicare  and  Medicaid,  and  private  healthcare  insurers  are  critical  to  new  product
acceptance. Patients are unlikely to use our future products, if any, unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost.

Cost-containment is a priority in the U.S. healthcare industry and elsewhere. As a result, government authorities and other third-party payors have attempted to control
costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with
predetermined discounts from list prices and are challenging the prices charged for medical products. Third-party payors also may request additional clinical evidence beyond
the data required to obtain marketing approval, requiring a company to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-
effectiveness of its products. Commercial third-party payors often rely upon Medicare coverage policy and payment limitations in setting their reimbursement rates, but also
have their own methods and approval process apart from Medicare determinations. Therefore, coverage and reimbursement for pharmaceutical products in the U.S. can differ
significantly from payor to payor. We cannot be sure that coverage and adequate reimbursement will be available for any product that we commercialize and, if reimbursement
is available, that the level of reimbursement will be adequate. Coverage and reimbursement may impact the demand for, or the price of, any drug candidate for which we obtain
marketing  approval.  If  coverage  and  reimbursement  are  not  available  or  are  available  only  at  limited  levels,  we  may  not  be  able  to  successfully  commercialize  any  drug
candidate for which we obtain marketing approval.

Additionally, the regulations that govern regulatory approvals, pricing and reimbursement for new drugs and therapeutic biologics vary widely from country to country.
Some countries require approval of the sale price of a drug or therapeutic biologic before it can be marketed. 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  regulatory  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 one or more drug candidates, even if our drug candidates obtain regulatory approval.

Politically  divided  governmental  actions  and  related  political  actions  outside  of  government  can  impact  the  FDA’s  role  in  the  timely  and  effective  review  of  new
pharmaceutical products in the U.S. and our business may be adversely impacted.

A relevant example of dysfunctional government was the 35-day government shutdown that ended February 15, 2019, which limited the FDA to activities necessary to
address imminent threats to human life and to activities funded by carry-over user fees. Future government shutdowns or other activities which limit the financial resources
available to the FDA (and in particular to the Center for Drug Evaluation and Research) will delay the processing of new product drug development submissions, reviews, and
approvals and other required regulatory actions. Such delays will adversely impact our business and financial condition.

57

 
 
 
 
 
 
 
 
 
Table of Contents

Effective collaboration with the FDA’s Center for Drug Evaluation and Research (“CDER”) for the approval of drug candidates is a highly demanding process which can
result in increased time and expense to gain approvals.

Our lead drug development program, Validive, will be reviewed by CDER. Efficient and professional collaboration with the FDA’s CDER is essential for the timely
clinical testing, test evaluations, analysis and approval of our drug candidates. CDER has an outstanding record of drug approvals and substantial funds to operate a highly
professional organization but is also very demanding as to the quality of clinical research and applications for marketing approvals for drug candidates.

Our Company has in-house expertise and experience in the management of drug approvals. Qualified consultants and drug research organizations are also available to
aid in our drug approval process; however, there is a meaningful risk that discussions and interactions inherent in the drug approval process and future developments or new
improvements will result in delays, added expenses and new scientific/medical requirements which will cause adverse financial results and will likely impact the price of the
Company’s stock.

Future tax reform measures may negatively impact our financial position.

Tax reform measures are unpredictable and can change as the U.S. Congress and executive leadership changes. For example, on December 22, 2017, the Tax Cuts and
Jobs Act of 2017 was signed into law that significantly revised the Internal Revenue Code of 1986, as amended (the “Code”). It is difficult to predict what future tax reform
measures, if any, could be implemented and the extent to which they will impact our financial condition and our business.

Foreign currency exchange rates may adversely affect our consolidated financial statements.

Sales and purchases in currencies other than the U.S. Dollar expose us to fluctuations in foreign currencies relative to the U.S. Dollar and may adversely affect our
consolidated financial statements. Increased strength of the U.S. Dollar increases the effective price of our future drug products sold in U.S. Dollars into other countries, which
may require us to lower our prices or adversely affect sales to the extent we do not increase local currency prices. Decreased strength of the U.S. Dollar could adversely affect
the cost of materials, products and services we purchase overseas. Sales and expenses of our non-U.S. businesses are also translated into U.S. Dollars for reporting purposes and
the strengthening or weakening of the U.S. Dollar could result in unfavorable foreign currency translation and transaction effects. In addition, certain of our businesses may in
the future invoice customers in a currency other than the business’ functional currency, and movements in the invoiced currency relative to the functional currency could also
result in unfavorable foreign currency translation and transaction effects. We also face exchange rate risk from our investments in subsidiaries owned and operated in foreign
countries.

Our anticipated operating expenses and capital expenditures over the next year are based upon our management’s estimates of possible future events. Actual amounts and
the cost of new conditions could differ materially from those estimated by our management.

Development of pharmaceuticals and cancer drugs is extremely risky and unpredictable. We have estimated operating expenses and capital expenditures over the next
year based on certain assumptions. Any change in the assumptions could cause the actual results to vary substantially from the anticipated expenses and expenditures and could
result in material differences in actual versus forecasted expenses or expenditures. Furthermore, all of the factors are subject to the effect of unforeseeable future events. The
estimates  of  capital  expenditures  and  operating  expenses  represent  forward-looking  statements  within  the  meaning  of  the  federal  securities  laws.  Prospective  investors  are
cautioned that any such forward-looking statements are not guarantees of future performance and involve risks and uncertainties. Actual events or results may differ materially
from those discussed in the forward-looking statements as a result of various factors, including the risk factors set forth under this “Risk Factors” section in this Annual Report
on Form 10-K.

The financial and operational projections that we may make from time to time are subject to inherent risks.

The projections that we provide herein or our management may provide from time to time (including, but not limited to, our success in raising strategic and substantial
financial resources, the cost and timing of our clinical trials, clinical and regulatory timelines, production and supply matters, commercial launch dates, and other financial or
operational  matters)  reflect  numerous  assumptions  made  by  our  management,  including  assumptions  with  respect  to  our  specific  as  well  as  general  business,  regulatory,
economic, market and financial conditions and other matters, all of which are difficult to predict and many of which are beyond our control. Accordingly, there is a risk that the
assumptions made in preparing the projections, or the projections themselves, will prove inaccurate. There may be differences between actual and projected results, and actual
results may be materially different from those contained in the projections. The inclusion of the projections in this Annual Report on Form 10-K should not be regarded as an
indication that our management considered or consider the projections to be a guaranteed prediction of future events, and the projections should not be relied upon as such. See
“Cautionary Statement Concerning Forward-Looking Statements.”

Our present and potential future international operations may expose us to business, political, operational, and financial risks associated with doing business outside of the
U.S.

Our business is subject to risks associated with conducting business internationally. Some of our suppliers and clinical research organizations and clinical trial sites are
located outside of the U.S. Furthermore, if we or any future collaborator succeeds in developing any products, we anticipate marketing them in the EU, the United Kingdom and
other jurisdictions in addition to the U.S. If approved, we or our collaborator may hire sales representatives and conduct physician and patient association outreach activities
outside of the U.S. Doing business internationally involves a number of risks, including but not limited to:

●

●

●

●

●

●

●

●

●

●

●

●

multiple, conflicting and changing laws and regulations such as privacy regulations, tax laws, export and import restrictions, employment laws, regulatory
requirements, and other governmental approvals, permits and licenses which can vary jurisdictions to jurisdiction with different degrees of review and
enforcement;

failure by us to obtain and maintain regulatory approvals for the use of our products in various countries;

rejection or qualification of foreign clinical trial data by the competent authorities of other countries;

additional potentially relevant third-party patent and other intellectual property rights that may be necessary to develop and commercialize our products and drug
candidates;

complexities and difficulties in obtaining, maintaining, enforcing and defending our patent and other intellectual property rights;

difficulties in staffing and managing foreign operations by a small-scale organization;

complexities associated with managing multiple payor reimbursement regimes, government payors or patient self-pay systems;

limits, as a U.S.-based company, in our ability to penetrate international markets;

financial risks, such as longer payment cycles, difficulty collecting accounts receivable, the impact of local and regional financial crises on demand and payment
for our products and exposure to foreign currency exchange rate fluctuations;

natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease, boycotts, curtailment of trade and other
business restrictions, implementation of tariffs;

certain expenses including, among others, expenses for travel, translation and insurance; and

regulatory  and  compliance  risks  that  relate  to  anti-corruption  compliance  and  record-keeping  that  may  fall  within  the  purview  of  the  U.S.  Foreign  Corrupt
Practices Act, its accounting provisions or its anti-bribery provisions or provisions of anti-corruption or anti-bribery laws in other countries.

Any  of  these  factors  could  harm  our  ongoing  international  clinical  operations  and  supply  chain,  as  well  as  any  future  international  expansion  and  operations  and,

consequently, our business, financial condition, prospects and results of operations.

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to
criminal or civil liability and harm our business.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended (“the FCPA”), the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S.
Travel Act,  the  USA  PATRIOT Act,  and  possibly  other  state  and  national  anti-bribery  and  anti-money  laundering  laws  in  countries  in  which  we  conduct  activities. Anti-
corruption  laws  are  interpreted  broadly  and  prohibit  companies  and  their  employees,  agents,  third-party  intermediaries,  joint  venture  partners  and  collaborators  from
authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We interact with officials and
employees of government agencies and government-affiliated hospitals, universities and other organizations. In addition, we may engage third-party intermediaries to promote
our clinical research activities abroad or to obtain necessary permits, licenses and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of
these  third-party  intermediaries,  our  employees,  representatives,  contractors,  partners  and  agents,  even  if  we  do  not  explicitly  authorize  or  have  actual  knowledge  of  such
activities.

We have a Code of Business Conduct and Ethics which mandates compliance with the FCPA and other anti-corruption laws applicable to our business throughout the
world. However, we cannot assure you that our employees and third-party intermediaries will comply with this code or such anti-corruption laws. Noncompliance with anti-
corruption  and  anti-money  laundering  laws  could  subject  us  to  whistleblower  complaints,  investigations,  sanctions,  settlements,  prosecution,  other  enforcement  actions,
disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of
export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas, investigations or other enforcement actions are launched, or
governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could
be  materially  harmed.  In  addition,  responding  to  any  action  will  likely  result  in  a  materially  significant  diversion  of  management’s  attention  and  resources  and  significant
defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can
result in added costs and administrative burdens.

Risks Associated with our Common Stock

Existing and new investors will experience dilution as a result of future sales or issuances of our common stock and future option exercises under our 2016 Stock Incentive
Plan and any amendments to the plan.

Our non-employee directors, employees, and certain of our consultants have been and will be issued equity and/or granted options that vest with the passage of time.
Up to a total of 5,100,000 shares of our common stock may be issued as stock options or restricted stock units under the Amended and Restated Monopar Therapeutics Inc.
2016  Stock  Incentive  Plan,  and  stock  options  for  the  purchase  of  up  to  2,147,790  shares  of  our  common  stock  have  already  been  granted  (1,215,724  stock  options  are
exercisable) and are outstanding along with 633,042 restricted stock units that have been granted to non-employee directors and employees as of March 10, 2023. The issuance
of such equity upon vesting of restricted stock units and/or the exercise of such options will dilute both our existing and our new investors. As of March 10, 2023, 189,346
stock options have been exercised.

Our  existing  and  our  new  investors  will  also  experience  substantial  dilution  resulting  from  the  issuance  by  us  of  equity  securities  in  connection  with  certain
transactions, including without limitation, future offering of shares in future fundraising efforts, intellectual property licensing, acquisition, or commercialization arrangements.

Holders of the shares of our common stock will have no control of our operations or of decisions on major transactions.

Our business and affairs are managed by or under the direction of our Board. Our stockholders are entitled to vote only on actions that require a stockholder vote under
federal or state law. Stockholder approval requires the consent and approval of holders of a majority or more of our outstanding stock. Shares of stock do not have cumulative
voting  rights  and  therefore,  holders  of  a  majority  of  the  shares  of  our  outstanding  stock  will  be  able  to  elect  all  Board  members.  TacticGem,  LLC  (“TacticGem”)  owns
7,166,667  shares  of  common  stock  (54.34%).  The  limited  liability  company  agreement  requires  TacticGem  to  pass  through  votes  (including  the  vote  for  the  election  of
directors) to its members in proportion to their membership percentages in TacticGem (57.367% owned by Tactic Pharma and 42.633% owned by Gem). As a result, Tactic
Pharma, our initial investor, holds an approximately 32.4% beneficial interest in us and together with Gem’s beneficial ownership of approximately 23.2%, the two entities
control a majority of our stock and will be able to elect all Board members and control our affairs. Some of our Board members and executive officers own and control Tactic
Pharma. Although no single person has a controlling interest in Tactic Pharma, acting together, they are able to control Tactic Pharma and a large voting block of our common
stock and together with Gem can elect a majority of our Board.

Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a de-listing of our common stock.

If we fail to satisfy the continued listing requirements of The Nasdaq Capital Market, such as the corporate governance requirements or the minimum closing bid price
requirement, the Nasdaq Stock Market (“Nasdaq”) may take steps to de-list our common stock. Such a de-listing or the announcement of such de-listing will have a negative
effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a de-listing, we would take
actions to restore our compliance with the Nasdaq listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to
become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq minimum bid price
requirement or prevent future non-compliance with the Nasdaq listing requirements.

The stock price of our common stock may be volatile or may decline regardless of our operating performance.

The  market  prices  for  securities  of  biotechnology  and  pharmaceutical  companies  have  historically  been  highly  volatile,  and  the  market  has  from  time-to-time
experienced  significant  price  and  volume  fluctuations  that  appear  to  be  unrelated  to  the  operating  performance  of  particular  companies.  Our  common  stock  has  only  been
trading on the Nasdaq Capital Market since December 19, 2019, and has experienced significant volatility in market prices through March 10, 2023, ranging from a low of
$1.39 to a high of $48.00. Our small public float and relatively low and inconsistent trading volumes exacerbate volatility.

The market price of our common stock is likely to remain highly volatile and may fluctuate substantially due to many factors, including:

announcements concerning the progress and success of our clinical trials, our ability to obtain regulatory approval for and commercialize our product candidates,
including  any  requests  we  receive  from  the  FDA  for  additional  studies  or  data  that  result  in  delays  in  obtaining  regulatory  approval  or  launching  our  product
candidates, if approved;

unstable market conditions in the pharmaceutical and biotechnology sectors or the economy as a whole;

price and volume fluctuations in the overall stock market;

the failure of our product candidates, if approved, to achieve anticipated commercial success; in the time projected by securities analysts and others;

announcements of the clinical success, NDA approval or introduction of new products by us or our direct competitors;

announcements of developments concerning product development results or intellectual property rights of others;

litigation or public concern about the safety and/or efficacy of our potential or approved products;

actual  fluctuations  in  our  quarterly  or  annual  operating  results,  and  concerns  by  investors  that  such  fluctuations  may  occur  in  the  future  and  are  indicative  of
internal problems;

deviations in our operating results from the estimates of securities analysts or other analyst comments;

additions or departures of key personnel;

healthcare  reform  legislation,  including  measures  directed  at  controlling  the  pricing  of  pharmaceutical  products,  and  third-party  coverage  and  reimbursement
policies;

announcements or publicity concerning current or future strategic collaborations;

discussion of our Company, our stock price or our potential future market value by the financial and scientific press and online investor communities; and

market responses to the fluctuating conditions of COVID-19 or to the Russia-Ukraine war.

 We may become involved in securities class action litigation that could divert management’s attention and harm our business.

The  stock  markets  have  from  time-to-time  experienced  significant  price  and  volume  fluctuations  that  have  affected  the  market  prices  for  the  common  stock  of
biotechnology and pharmaceutical companies. Our stock price has experienced such fluctuations since our initial public offering. These broad market fluctuations may cause
the market price of our stock to advance or decline. 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  biotechnology  and  biopharmaceutical  companies  have  experienced  significant  stock  price  volatility  in  recent
years. We may become involved in this type of litigation in the future. Litigation often is expensive and diverts management’s attention and resources, which could adversely
affect our business.

Substantial amounts of our outstanding shares may be sold into the market. If there are substantial sales of shares of our common stock, the price of our common stock
could decline.

The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by our non-employee directors, executive officers
and significant stockholders, or if there is a large number of shares of our common stock available for sale and the market perceives that sales will occur. We have 13,193,172
outstanding shares of our common stock as of March 10, 2023. A majority of our outstanding shares of common stock are currently held by non-employee directors, executive
officers and other affiliates and are subject to volume limitations under Rule 144 under the Securities Act of 1933, as amended (Securities Act).

Our  largest  stockholders  have  rights,  subject  to  some  conditions,  to  require  us  to  file  registration  statements  covering  their  shares  or  to  include  their  shares  in
registration  statements  that  we  may  file  for  ourselves  or  our  stockholders.  We  have  also  registered  shares  of  common  stock  that  we  have  issued  and  may  issue  under  our
employee equity incentive plans. These shares are able to be sold freely in the public market upon issuance, subject to existing internal practices which prohibit sales under
certain circumstances. The market price of the shares of our common stock could decline as a result of the sale of a substantial number of our shares of common stock in the
public market or the perception in the market that the holders of a large number of shares intend to sell their shares.

Our ability to use our net operating loss carry-forwards and certain other tax attributes may be limited.

Under Section 382 of the Code, if a corporation undergoes an “ownership change” (generally defined as a greater than 50% change, by value, in its equity ownership
over a three-year period), the corporation’s ability to use its pre-change net operating loss carry-forwards and other pre-change tax attributes (such as research tax credits) to
offset its post-change income may be limited. We believe that additional fundraising efforts in the next three years, may trigger an “ownership change” limitation in the near
future. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carry-forwards to offset U.S. federal taxable income will be subject to
limitations, which could result in increased future tax liability to us had we not been subject to such limitations.

If  securities  or  industry  analysts  do  not  publish  research  or  publish  inaccurate  or  unfavorable  research  about  our  business,  our  stock  price  and  trading  volume  could
decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our business. If one or
more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price may decline. If one or more of
these analysts ceases coverage of our Company or fails to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading
volume to decline.

We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of
our common stock.

We have never declared or paid any cash dividends on our capital stock, and we do not intend to pay any cash dividends in the foreseeable future. Any determination to
pay dividends in the future will be at the discretion of our Board. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never
occur, as the only way to realize any future gains as a return on their investments.

There can be no assurance that we will ever provide liquidity to our investors through a sale of our Company.

While  acquisitions  of  pharmaceutical  companies  like  ours  are  not  uncommon,  potential  investors  are  cautioned  that  no  assurances  can  be  given  that  any  form  of
merger,  combination,  or  sale  of  our  Company  will  take  place  or  that  any  merger,  combination,  or  sale,  even  if  consummated,  would  provide  liquidity  or  a  profit  for  our
investors. You should not invest in our Company with the expectation that we will be able to sell the business in order to provide liquidity or a profit for our investors.

Delaware law and provisions in our amended and restated bylaws could make a merger, tender offer or proxy contest difficult, thereby depressing the potential trading price
of our common stock.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us difficult, limit attempts by our stockholders to replace or

remove our current management or Board and adversely affect our stock price.

Provisions  of  our  amended  and  restated  bylaws  may  delay  or  discourage  transactions  involving  an  actual  or  potential  change  in  our  control  or  change  in  our
management, including transactions in which stockholders might otherwise receive a premium for their shares, or transactions that our stockholders might otherwise deem to be
in their best interests. Therefore, these provisions could adversely affect the price of our stock. Among other things, our amended and restated bylaws:

●

●

●

provide that all vacancies on our Board may only be filled by our Board and not by stockholders;

allow the holders of a plurality of the shares of common stock entitled to vote in any election of directors to elect all of the directors standing for election, if they
should so choose; and

provide that special meetings of our stockholders may be called only by our Board.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally
prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the
date on which the stockholder became an “interested” stockholder.

Item 2. Properties

We are currently leasing office space for our executive headquarters at 1000 Skokie Blvd in the Village of Wilmette, Illinois for our corporate offices. We believe that

we will lease additional office space within the next 12 months as we continue to hire additional personnel.

Item 3. Legal Proceedings

We are currently not, and to date have never been, a party to any adverse material legal proceedings.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our common stock is listed under the symbol “MNPR” on the Nasdaq Capital Market.

Holders

As of March 10, 2023, there were 13,193,172 shares of our common stock outstanding held by 30 holders of record and approximately 2,700 beneficial stockholders.

Dividends

We have never paid cash dividends on any of our capital stock and we currently intend to retain our future earnings, if any, to fund the development and growth of our

business. We do not intend to pay cash dividends to holders of our common stock in the foreseeable future.

Registration Rights

We  are  subject  to  an  agreement  with  TacticGem,  LLC  (“TacticGem”),  our  largest  stockholder,  which  obligates  us  to  file  a  Form  S-3  or  other  appropriate  form  of
registration statement covering the resale of any of our common stock by TacticGem, or its members Gem Pharmaceuticals, LLC, or Tactic Pharma, LLC, upon direction by
TacticGem. We are required to use our best efforts to have such registration statement declared effective as soon as practical after it is filed. In the event that such registration
statement for resale is not approved by the SEC, and TacticGem submits a written request, we are required to prepare and file a registration statement on Form S-1 registering
such common stock for resale and to use our best efforts to have such registration statement declared effective as soon as practical thereafter. Additionally, if we propose to
register our common stock for sale for cash, TacticGem and its members have the right to include some of their shares in such registration After registration, pursuant to these
rights, these shares will become freely tradable without restriction under the Securities Act other than pursuant to restrictions on affiliates under Rule 144.

Recent Sales of Unregistered Securities.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You  should  read  the  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  together  with  our  financial  statements  and  related  notes
appearing at the end of this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on
Form 10-K, including information with respect to our plans and strategy for our business and related financing activities, includes forward-looking statements that involve risks
and uncertainties. You should read the “Risk Factors” section of this Annual Report on Form 10-K, Item 1A, for a discussion of important factors that could cause actual results
to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical stage biopharmaceutical company focused on developing proprietary therapeutics designed to extend life or improve quality of life for cancer patients.
We are building a drug development pipeline through the licensing and acquisition of therapeutics in late preclinical or in clinical development stages. We leverage our scientific
and clinical experience to help reduce the risk of and accelerate the clinical development of our drug product candidates.

Financial Status

Our cash, cash equivalents and investments as of December 31, 2022, was $13.1 million. As discussed further below and elsewhere in this Annual Report, we expect
that our current funds will be sufficient for us to obtain topline results from our ongoing open-label Phase 1b camsirubicin clinical trial as planned by the end of 2023 (but as
discussed below, this may not be the case if camsirubicin reaches even higher dose levels than we are anticipating and topline results are deferred as dosing continues beyond
2023) and, assuming a positive result of the go/no go interim analysis decision anticipated by the end of March 2023, the continued enrollment in the Phase 3 portion of our
ongoing Validive Phase 2b/3 (VOICE) clinical program. We will require additional funding to advance our clinical and preclinical programs and we anticipate that we will seek
to raise additional capital within the next 12 months to fund our future operations.

Our primary funding source over the past three years was sales of shares of our common stock under at-the-market sales programs through Capital on DemandTM Sales
Agreements with JonesTrading Institutional Services LLC (“Jones Trading”). During 2020 and the first quarter of 2021, we sold 1,964,724 shares of our common stock at an
average  gross  price  of  $10.02  per  share  for  net  proceeds  of  $19,100,603,  after  fees  and  commissions  of  $591,188.  The  maximum  aggregate  offering  price  under  the  prior
agreement was reached during the first quarter of 2021 and there were no further sales under that agreement. In April 2022, we entered into a new at-the-market sales agreement.
Pursuant to that agreement, during 2022, the Company sold 64,573 shares of its common stock at an average gross price per share of $2.71 for net proceeds of $170,552, after
fees and commissions of $4,377. In addition, the Company incurred legal, accounting and other fees totaling $83,234 for net proceeds after fees, commissions and expenses of
$87,318. From January 1, 2023 to March 10, 2023, the Company sold 241,475 shares of its common stock at an average gross price per share of $3.47 for net proceeds of
$836,836, after fees and commissions of $20,940.

Validive Clinical Update

In February 2021, we dosed the first patient in our Phase 2b/3 VOICE trial of Validive® for the prevention of chemoradiation treatment (“CRT”)-induced severe oral
mucositis (“SOM”) in patients  with  oropharyngeal cancer (“VOICE”). In August 2021,  we  successfully  reached  our  original  target  of  20  activated  clinical  trial  sites  for  the
Phase 2b portion of the 2b/3 Validive® VOICE trial and in September 2021, we received authorization to proceed with the VOICE clinical trial in multiple countries in Europe.
In 2022, we completed enrollment of the Phase 2b portion of the VOICE trial and commenced enrollment in the Phase 3 portion. As of March 10, 2023, we have 81 clinical
sites activated and enrolling patients in the U.S. and Europe. To be prepared for a potential positive go/no-go decision based on the interim analysis, we continue to activate
additional sites globally. This interim analysis, and the resulting go/no-go decision about whether to proceed to the Phase 3 portion of the trial, is expected by the end of March
2023. If the interim analysis results in a no-go decision, we would need to reconsider our efforts with respect to Validive and refocus our development efforts on our other
product candidates. Validive has been our lead product candidate to date and is the most clinically advanced, and if we had to reconsider or abandon our efforts, it would likely
materially  adversely  impact  our  financing  prospects,  as  well  as  the  price  of  our  common  stock.  Because  the  interim  analysis  is  being  performed  by  an  independent  data
monitoring committee, we do not know what the results will be as of the date of this Annual Report.

Table of Contents

To  complete  the  VOICE  clinical  program,  including,  if  required,  completing  a  second  Phase  3  confirmatory  clinical  trial,  we  will  require  additional  funding  in  the
millions or tens of millions of dollars (depending on if we have consummated a collaboration or partnership or neither for Validive), which we are planning to pursue within the
next 12 months.

Camsirubicin Clinical Update

In August 2021, we announced clearance from the U.S. Food and Drug Administration (“FDA”) to proceed with an open-label Phase 1b dose-escalation clinical trial
evaluating camsirubicin plus growth factor support (pegfilgrastim/G-CSF) in patients with advanced soft tissue sarcoma (“ASTS”). In September 2021, we initiated the Phase
1b clinical trial, and in October 2021 we dosed the first patients. In February 2022, we announced that the first dose level of camsirubicin had been completed in November
2021, with a positive recommendation from the trial safety review committee to proceed to next higher dose level and that three patients had already been dosed at the second
dose level. That dose level was successfully cleared, as was the third and fourth dose levels, and we are presently enrolling patients at the fifth dose level. The fifth dose level is
over twice the highest dose administered in any prior camsirubicin clinical trial (650 mg/m2 versus 265 mg/m2) and no drug-related cardiotoxicity has been observed to date up
to the current dose-level. The open-label Phase 1b camsirubicin dose-escalation trial is planning to enroll additional cohorts until the maximum tolerable dose is reached.

In November 2022, we presented an abstract and poster of the Phase 1b clinical trial data at the Connective Tissue Oncology Society Annual Meeting in Vancouver,
BC.  Following  completion  of  the  Phase  1b  clinical  trial,  we  continue  to  expect  that  Grupo  Español  de  Investigación  en  Sarcomas  (“GEIS”)  will  sponsor  and  lead  a  multi-
country,  randomized,  open-label  Phase  2  clinical  trial  to  evaluate  camsirubicin  head-to-head  against  doxorubicin,  the  current  first-line  treatment  for ASTS.  We  currently
anticipate topline results in the camsirubicin Phase 1b clinical trial by the end of 2023 and believe we have sufficient funds to advance the trial through that date. However, if
camsirubicin  reaches  higher  dose  levels  than  we  are  anticipating,  the  Phase  1b  clinical  trial  may  still  be  dosing  patients  beyond  the  end  of  2023  and  topline  results  may  be
deferred. Although we would likely consider this a positive development, it is possible that we would require additional funding to complete an extended Phase 1b clinical trial
in this situation. Regardless, additional funding is expected to be required to support further development through and beyond our ongoing Phase 1b clinical trial. 

  MNPR-101 for Radiopharmaceutical Use Development Update

 Pursuant to our 50/50 collaboration development agreement with NorthStar Medical Radioisotopes, LLC (“NorthStar”) to develop potential radioimmunotherapeutics
based on MNPR-101 (“MNPR-101 RITs”), we have coupled MNPR-101 to imaging and therapeutic radioisotopes. The resulting conjugates, MNPR-101-Zr and MNPR-101-
PCTA-Ac225, are designed to be highly selective agents that have the potential to image and kill certain cancer cells. By eradicating these cancer cells with a uPAR-targeted
RIT (“uPRIT”), the therapeutic goal is to spare healthy cells while quickly killing the cancer cells.

Based on promising recently generated preclinical imaging results with MNPR-101-Zr showing high uptake across multiple tumor types, the companies committed to
additional funding with the aim of initiating a first-in-human imaging study with MNPR-101-Zr as early as the end of this year. MNPR-101-Zr is a zirconium-89 labeled version
of  MNPR-101,  a  highly  selective  antibody  against  the  urokinase  plasminogen  activator  receptor  (“uPAR”).  Positron  emission  tomography  (“PET”)  imaging  of  preclinical
mouse models for triple-negative breast, colorectal, and pancreatic tumors displayed high and selective uptake of MNPR-101-Zr in these uPAR-expressing tumors. These proof-
of-concept studies provide support for a first-in-human PET imaging study with MNPR-101-Zr and a future therapeutic study using the previously announced actinium-225
labeled MNPR-101 RIT. Overall, the imaging results demonstrate the potential utility of MNPR-101 as a precision targeting agent for both imaging and therapy in multiple
cancer indications.

MNPR-202 and Related Analogs Updates

In  June  2021,  we  entered  into  a  collaboration  agreement  with  the  Cancer  Science  Institute  of  Singapore  (“CSI  Singapore”),  one  of Asia’s  premier  cancer  research
centers, at the National University of Singapore (“NUS”) (consistently ranked as one of the world’s top universities) to evaluate the activity of MNPR-202 and related analogs
in multiple types of cancer. MNPR-202 was designed to retain the same potentially non-cardiotoxic backbone as camsirubicin but is modified at other positions which may
enable it to work in certain cancers that are resistant to camsirubicin and doxorubicin. In December 2020, we announced the issuance of our composition of matter U.S. patent
(US10,450,340)  covering  MNPR-202  and  related  analogs.  CSI  Singapore  has  tested  MNPR-202  in  preclinical  cancer  models  with  promising  results.  In  December  2022,  in
collaboration with Dr. Anand Jeyasekharan of CSI Singapore, we presented an abstract and poster of the preclinical data of MNPR-202 at the American Society of Hematology
64th Annual Meeting in New Orleans, LA.

Our Strategy

Our management team has extensive  experience  in  developing  therapeutics  and  medical  technologies  through  global  regulatory  approval  and  commercialization.  In
aggregate, companies they co-founded have achieved four drug approvals and three diagnostic medical imaging device approvals in the U.S. and the EU, successfully sold an
asset  developed  by  management  which  is  currently  in  Phase  3  clinical  trials,  sold  two  oncology-focused  diagnostic  imaging  businesses  to  Fortune  Global  1000  firms,  and
completed the clinical and commercial development and ultimately the sale of a commercial biopharmaceutical company for over $800 million in cash. In addition, the team has
supported multiple regulatory submissions with the FDA and EMA and launched multiple drugs in the U.S and the EU. Understanding the preclinical, clinical, regulatory and
commercial development processes and hurdles are key factors in successful drug development and the expertise demonstrated by our management team across all of these
areas increases the probability of success in advancing the product candidates in our product pipeline. Our strategic goal is to acquire, develop and commercialize promising
oncology product candidates that address important unmet medical needs of cancer patients. Seven key elements of our strategy to achieve this goal are to:

Leverage data generated from the Phase 2 Validive clinical trial to complete the execution of a hopefully successful VOICE clinical program for Validive
for SOM in oropharyngeal cancer (“OPC”). In the prior Phase 2 clinical trial the absolute incidence of SOM in OPC patients was reduced by 26.3%, the time
to SOM onset was delayed, and the duration of disease in patients that developed SOM was decreased by 15.5 days in the Validive 100 µg cohort versus placebo.
In addition to the data from the Phase 2 clinical trial, we believe the guidance from our key opinion leaders (“KOLs”) as well as from the FDA and EMA, and our
own internal clinical trial design expertise, help position us well for an effective VOICE clinical trial program.

Obtain  FDA  and  EMA  approval  of  Validive  to  maximize  the  commercial  potential  of  Validive  in  both  the  U.S.  and  the  EU,  and  seek  marketing
partnerships outside these markets. If the VOICE clinical program of Validive is successful and FDA and EMA approvals are obtained, we currently intend to
commercialize Validive in the U.S. and the EU ourselves, which may include establishing our own specialty sales force and seeking partnerships outside of these
territories for regulatory approval and drug sales and distribution.

Advance the clinical development of camsirubicin, by pursuing indications where doxorubicin has demonstrated efficacy. ASTS will be the first indication,
which  is  anticipated  to  allow  camsirubicin  to  go  head-to-head  against  doxorubicin,  the  current  first-line  treatment.  In  this  indication,  camsirubicin  previously
demonstrated  clinical  benefit  (stable  disease  or  partial  response)  in  52.6%  of  patients  evaluable  for  tumor  progression  in  a  single-arm  Phase  2  study.  Clinical
benefit was proportional to dose and was consistently observed at higher cumulative doses of camsirubicin (>1000 mg/m2). Camsirubicin was very well tolerated
in this Phase 2 study and underscored the ability to potentially administer camsirubicin without restriction as to cumulative dose (doxorubicin is limited due to
heart toxicity to 450 mg/m2 cumulative dose). Our current ongoing Phase 1b clinical trial continues towards establishing a new, higher recommended dose for the
next Phase 2 ASTS clinical trial.

Continue the development of MNPR-101-Zr, MNPR-101 RIT and related molecules as therapeutic, diagnostic and imaging agents. We plan to continue
the development of MNPR-101-Zr, MNPR-101 RIT and related molecules for diagnostic, imaging, and therapeutic use in cancer.

Continue  the  development  of  MNPR-202  and  related  analogs  in  multiple  types  of  cancers. The  2-pyrrilino  camsirubicin  analog  (MNPR-202)  and  related
analogs  represent  proprietary  compositions  of  matter  designed  to  retain  the  non-cardiotoxic  backbone  of  camsirubicin  yet  exhibit  novel  features  in  terms  of
antitumor  activity  and  mechanism  that  distinguish  these  analogs  from  camsirubicin  as  well  as  from  doxorubicin,  potentially  addressing  camsirubicin-  and
doxorubicin-resistant cancers.

Expand  our  drug  development  pipeline  through  advancing  current  assets,  in-licensing,  and  acquisition  of  oncology  product  candidates.  We  plan  to
continue  the  expansion  of  our  drug  development  pipeline  through  acquiring  or  in-licensing  additional  oncology  product  candidates,  particularly  those  that
leverage existing scientific and clinical data that helps reduce the risks of the next steps in clinical development.

Utilize the expertise and prior experience of our team in the areas of asset acquisition, drug development and commercialization to establish ourselves as
a  leading  biopharmaceutical  company.  Our  senior  executive  team  has  relevant  experience  in  biopharmaceutical  in-licensing  and  acquisitions  as  well  as
developing  product  candidates  through  approval  and  commercialization.  In  aggregate,  our  team  has  co-founded  BioMarin  Pharmaceutical  (Nasdaq:  BMRN),
Sensant Corp (acquired by Siemens), American BioOptics (assets acquired by Olympus), Raptor Pharmaceuticals ($800 million sale to Horizon Therapeutics), and
Tactic Pharma, LLC (“Tactic Pharma”) (sale of lead asset, choline tetrathiomolybdate, was ultimately acquired by Alexion in June 2018 for $764 million; Alexion
was subsequently acquired by AstraZeneca).

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). An emerging growth company may take

advantage of specified reduced reporting burdens that are otherwise applicable generally to public companies. These provisions include, but are not limited to:

●

●

●

●

●

inclusion of only two years, as compared to three years, of audited financial statements in addition to any required unaudited interim financial statements with
correspondingly reduced “Management’s discussion and analysis of financial condition and results of operations” disclosures;

an exemption from the auditor attestation requirement in the assessment of our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of
2002 (“Sarbanes-Oxley Act”);

an exemption from compliance with any new requirements adopted by the Public Company Accounting Oversight Board (“PCAOB”) requiring mandatory audit
firm rotation;

reduced disclosure about executive compensation arrangements; and

an exemption from the requirement to seek non-binding advisory votes on executive compensation or golden parachute arrangements.

We expect to take advantage of these provisions until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of
(1) the last day of the year (a) following the fifth anniversary of the completion of our initial public offering which is December 2024, (b) in which we have total annual gross
revenue of at least
$1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700
million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

We  have  elected  to  take  advantage  of  certain  of  the  reduced  disclosure  obligations  in  this Annual  Report  on  Form  10-K,  and  may  elect  to  take  advantage  of  other
reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be reduced and/or less detailed than what you might find
from other public reporting companies.

The JOBS Act also permits an emerging growth company such as us to take advantage of an extended transition period to comply with new or revised accounting
standards applicable to public companies until those standards would otherwise apply to private companies. We have irrevocably elected to opt out of this provision and, as a
result, we will comply with new or revised accounting standards when they are required to be adopted by public companies that are not emerging growth companies. In addition,
we  are  also  a  “smaller  reporting  company”  as  defined  in  Rule  12b-2  of  the  Exchange  Act  and  have  elected  to  take  advantage  of  certain  of  the  scaled  back  disclosure
requirements available to smaller reporting companies such as avoiding the extensive narrative disclosure required of other reporting companies, particularly in the description
of executive compensation.

Revenues

We are an emerging growth company. We have no approved drugs and have not generated any revenues. To date, we have engaged in acquiring or in-licensing drug
product candidates, entering into collaboration agreements for testing and clinical development of our drug product candidates and providing the infrastructure to support the
clinical development of our drug product candidates. We do not anticipate commercial revenues from operations until we complete testing and development of one of our drug
product candidates and obtain marketing approval or we sell, enter into a collaborative marketing arrangement, or out-license one of our drug product candidates to another
party. See “Liquidity and Capital Resources”.

Recently Issued and Adopted Accounting Pronouncements

During  the  year  ended  December  31,  2022,  there  were  no  relevant  recently  issued  accounting  pronouncements  that  would  impact  our  financial  position  and  our

consolidated results of operations and comprehensive loss or cashflows.

Critical Accounting Policies and Use of Estimates

While our significant accounting policies are described in more detail in Note 2 of our consolidated financial statements included elsewhere in this Annual Report on

Form 10-K, we believe the following accounting policies to be critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Clinical Trials Accruals

We accrue and expense the costs for clinical trial activities performed by third parties based upon estimates of the percentage of work completed over the life of the
individual study in accordance with agreements established with contract research organizations, service providers, and clinical trial sites. We estimate the amounts to accrue
based upon discussions with internal clinical personnel and external service providers as to progress or stage of completion of trials or services and the agreed upon fee to be
paid for such services. Costs of setting up clinical trial sites for participation in the trials are expensed immediately as R&D expenses. Clinical trial site costs related to patient
screening and enrollment are accrued as patients are screened/entered into the trial.

Stock-Based Compensation

We  account  for  stock-based  compensation  arrangements  with  employees,  non-employee  directors  and  consultants  using  a  fair  value  method,  which  requires  the
recognition of compensation expense for costs related to all stock-based compensation grants, including stock option and restricted stock unit (“RSU”) grants. The fair value
method requires us to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model or the closing stock price on the date of grant in
the case of RSUs.

Stock-based  compensation  costs  for  stock  awards  granted  to  our  employees,  non-employee  directors  and  consultants  are  based  on  the  fair  value  of  the  underlying
instruments calculated using the Black-Scholes option-pricing model on the date of grant for stock options and using the closing stock price on the date of grant for RSUs and
recognized  as  expense  on  a  straight-line  basis  over  the  requisite  service  period,  which  is  the  vesting  period.  Determining  the  appropriate  fair  value  model  and  related
assumptions requires judgment, including selecting methods for estimating our future stock price volatility and expected holding term. The expected volatility rates are estimated
based on our actual historical volatility over the two-year period from our initial public offering on December 18, 2019, through December 31, 2021. The expected term for
stock options granted during the years ended December 31, 2022, and 2021, was estimated using the simplified method. Forfeitures only include actual forfeitures to-date as the
Company accounts for forfeitures as they occur due to a limited history of forfeitures. We have not paid dividends and do not anticipate paying a cash dividend in future vesting
periods and, accordingly, use an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the
estimated expected term of the awards.

R&D expenses for the year ended December 31, 2022 were $7,592,000, compared to $6,493,000 for the year ended December 31, 2021. This represents an increase of
$1,099,000 primarily attributed to (1) a $1,044,000 increase for Validive clinical trial planning and execution including manufacturing costs, (2) a $460,000 increase due to
camsirubicin clinical trial planning and execution including manufacturing costs, (3) a $193,000 increase in R&D consulting, partially offset by (1) a $534,000 decrease for
R&D personnel salaries, bonuses, benefits and annual (non-cash) equity grants and  (2) a $64,000 net decrease in other R&D expenses.

General and Administrative (“G&A") Expenses

G&A expenses for the year ended December 31, 2022, were $2,945,000, compared to $2,634,000 for the year ended December 31, 2021. This represents an increase of
$311,000 primarily attributed to (1) a $349,000 increase in G&A personnel salaries, bonuses, benefits and stock-based compensation for annual (non-cash) equity grants, and (2)
a $27,000 net increase in other G&A expenses partially offset by a $65,000 decrease in patent costs.

Interest Income

Interest  income  for  the  year  ended  December  31,  2022,  decreased  by  $3,000  versus  the  year  ended  December  31,  2021.  The  decrease  was  caused  by  lower  bank

balances offset by an increase in interest rates in 2022.

Liquidity and Capital Resources

Sources of Liquidity

We have incurred losses and cumulative negative cash flows from operations since we commenced operations resulting in an accumulated deficit of approximately
$51.8 million as of December 31, 2022. We anticipate that we will continue to incur losses for the foreseeable future. We expect that our R&D and G&A expenses will increase
to enable the execution of our strategic plan. As a result, we anticipate that we will seek to raise additional capital within the next 12 months to fund our future operations. We
will  seek  to  obtain  needed  capital  through  a  combination  of  equity  offerings,  including  the  usage  of  our  Capital  on  DemandTM Sales Agreement  with  JonesTrading,  debt
financings, strategic collaborations and grant funding. To date, we have funded our operations through net proceeds from the initial public offering of our common stock, net
proceeds from sales of our common stock through at-the-market sales programs, private placements of our preferred and common stock, and the net receipt of funds related to
the acquisition of camsirubicin. We anticipate that the currently available funds as of March 10, 2023, will fund our planned operations at least through March 31, 2024.

We invest our cash equivalents in two money market accounts and U.S. Treasury Bills.

During 2022, the Company began investing its idle cash due to the rising interest rates and at December 31, 2022, the Company holds short term liquid investments of
$4,934,000 which can be readily converted to cash. During the years ended December 31, 2022 and 2021, we had net cash outflows of $12,118,000 and net cash inflows of
$3,567,000, respectively, a decrease of $15,685,000. During 2022, we had higher net cash used investing activities and less funds raised from sales of our common stock under
an at-the-market sales program compared to 2021.

Cash Flow Used in Operating Activities

The cash flow used in operating activities during the year ended December 31, 2022, compared to the year ended December 31, 2021 was essentially flat.

Cash Flow Used in Investing Activities

The increase to cash flow used in investing activities during the year ended December 31, 2022, compared to the year ended December 31, 2021 of approximately
$4,919,000 was a result of our investment in U.S. Treasury Bills at the end of 2022. Prior to 2022, idle cash was invested in money market accounts and recorded  as  cash
equivalents.

Cash Flow Provided by Financing Activities

The  decrease  in  cash  flow  provided  by  financing  activities  during  the  year  ended  December  31,  2022,  compared  to  the  year  ended  December  31,  2021,  of

approximately $10,846,000 was primarily due to higher net proceeds from sales of our common stock through an at-the-market sales program in 2021.

Future Funding Requirements

To date, we have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to
generate any revenue from product sales or royalties unless and until we obtain regulatory approval of and commercialize any of our current or future drug product candidates
or we out-license or sell a drug product candidate to another party. At the same time, we expect our expenses to increase in connection with our ongoing development activities,
particularly  as  we  continue  the  research,  development,  future  preclinical  studies  and  clinical  trials  of,  and  seek  regulatory  approval  for,  our  current  and  future  drug  product
candidates.  If  we  obtain  regulatory  approval  of  any  of  our  current  or  future  drug  product  candidates,  we  will  need  substantial  additional  funding  for  commercialization
requirements and our continuing drug product development operations.

As a company, we have not completed development through marketing approvals of any therapeutic products. We expect to continue to incur significant increases in

expenses and increasing operating losses for the foreseeable future. We anticipate that our expenses will increase substantially as we:

advance the clinical development and execute the regulatory strategy for Validive, assuming a positive result of the go/no go interim analysis decision anticipated
by the end of March 2023;

advance the clinical development and execute the regulatory strategy for camsirubicin;

continue  the  preclinical  activities  and  potentially  enter  clinical  development  of  an  MNPR-101-derived  radioimmunotherapeutics  (MNPR-101  RIT)  and
companion diagnostics (MNPR-101-Zr), to treat cancer;

continue the preclinical activities, and potentially later-on enter clinical development, of MNPR-202 (and related analogs) for various cancer indications;

acquire and/or license additional pipeline drug product candidates and pursue the future preclinical and/or clinical development of such drug product candidates;

seek regulatory approvals for any of our current and future drug product candidates that successfully complete registration clinical trials;

establish or purchase the services of a sales, marketing and distribution infrastructure to commercialize any products for which we obtain marketing approval;

develop or contract for manufacturing/quality capabilities or establish a reliable, high quality supply chain sufficient to support our clinical requirements and to
provide sufficient capacity to launch and supply the market for any product for which we obtain marketing approval; and

add  or  contract  for  required  operational,  financial  and  management  information  systems  and  capabilities  and  other  specialized  expert  personnel  to  support  our
drug product candidate development and planned commercialization efforts.

We anticipate that the funds available as of March 10, 2023, will fund our obligations at least through March 31, 2024. We have based this estimate on assumptions
that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with
the development and commercialization of our drug product candidates, and the extent to which we enter into collaborations with third parties to participate in the development
and commercialization of our drug product candidates, we are unable to accurately estimate with high reliability the amounts and timing required for increased capital outlays
and operating expenditures associated with our current and anticipated drug product candidate development programs.

Our future capital requirements will depend on many factors, including:

·

·

·

·

·

·

the progress of clinical development and regulatory interactions and approvals of Validive;

the progress of clinical development and regulatory interactions and approvals of camsirubicin;

activities through our collaboration with NorthStar;

the progress of preclinical and potentially clinical development of MNPR-202 (and related analogs);

assuming a positive result of the go/no go interim analysis decision anticipated by the end of March 2023, clinical research services and clinical site fees for our
Phase 3 VOICE clinical program, including, if required, completing a second Phase 3 confirmatory clinical trial;

process  development,  manufacturing  costs,  clinical  trial  expenses  and  clinical  database  management  of  camsirubicin  in  connection  with  the  Phase  1b  dose
escalation clinical trial and other future clinical development;

support  of  the  development  of  MNPR-101-derived  radioimmunotherapeutics  (MNPR-101  RIT)  and  companion  diagnostics  (MNPR-101-Zr)  to  treat  cancer,
including activities through our collaboration with NorthStar;

preclinical studies (and if successful, clinical studies) of MNPR-202 (and related analogs); and

employee compensation and consulting fees to support the increased scope of activities required for the progress of our product candidate programs including
Validive, camsirubicin, MNPR-101 RIT (uPRIT and related compounds) and companion diagnostics (MNPR-101-Zr) and MNPR-202 (and related analogs).

We  have  activated  clinical  trial  sites  and  are  dosing  patients  in  our  VOICE  clinical  trial.  In  order  to  complete  the  VOICE  clinical  program,  including,  if  required,
completing a second Phase 3 confirmatory clinical trial, we will require additional funding in the millions or tens of millions of dollars (depending on if we have consummated a
collaboration or partnership or neither for Validive), or find a suitable pharmaceutical partner, both of which we are planning to pursue within the next 12 months. There can be
no assurance that any such events will occur. We have also initiated and commenced dosing in our Phase 1b camsirubicin clinical trial. We intend to continue evaluating drug
product candidates for the purpose of growing our pipeline. Identifying and securing high-quality compounds usually takes time and related expenses; however, our spending
could be significantly accelerated in 2023 and onward if additional drug product candidates are acquired and enter clinical development. In this event, we may be required to
expand our management team, and pay higher contract manufacturing costs, contract research organization fees, other clinical development costs and insurance costs that are
not currently projected. Beyond our need to raise additional funding within the next 12 months to complete the VOICE clinical program, additional long-term funding is needed
to  commercialize  Validive,  if  approved,  and  otherwise  generally  to  support  our  current  and  future  product  candidates  through  clinical  trials,  approval  processes  and,  if
applicable, commercialization.

Until  we  can  generate  a  sufficient  amount  of  product  revenue  to  finance  our  cash  requirements,  we  expect  to  finance  our  future  cash  needs  primarily  through  a
combination  of  equity  offerings,  including  the  usage  of  our  Capital  on  Demand™  Sales Agreement  with  JonesTrading,  debt  financings,  strategic  collaborations  and  grant
funding. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our current stockholders will be diluted,
and the terms of these securities may include liquidation or other preferences that adversely affect our current stockholders’ rights. Debt financing, if available, may involve
agreements  that  include  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 funds through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with other parties,
we likely will have to share or relinquish valuable rights to our technologies, future revenue streams, research programs or drug product candidates or grant licenses on terms
that may not be favorable to us, which will reduce our future returns and affect our future operating flexibility. If we are unable to raise additional funds through equity or debt
financings when needed,  we  may  be  required  to  delay,  limit,  reduce  or  terminate  our  pipeline  product  development  or  commercialization  efforts  or  grant  rights  to  others  to
develop and market drug product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

License, Development and Collaboration Agreements

Onxeo S.A.

In June 2016, we executed an agreement with Onxeo S.A., a French public company, which gave us the exclusive option to license (on a world-wide exclusive basis)
Validive (clonidine hydrochloride mucobuccal tablet; clonidine HCI MBT a mucoadhesive tablet of clonidine based on the Lauriad mucoadhesive technology. The agreement
includes clinical, regulatory, developmental and sales milestones that could reach up to $108 million if we achieve all milestones, and escalating royalties from 5% to 10% on
net sales. In September 2017, we exercised the option to license Validive from Onxeo for $1 million, but as of March 10, 2023, we have not been required to pay Onxeo any
other  funds  under  the  agreement.  We  will  need  to  raise  significant  funds  or  enter  into  a  collaboration  partnership  to  support  the  completion  of  clinical  development  and
marketing approval of Validive.

Under  the  agreement,  we  are  required  to  pay  royalties  to  Onxeo  on  a  product-by-product  and  country-by-country  basis  until  the  later  of  (1)  the  date  when  a  given
product is no longer within the scope of a patent claim in the country of sale or manufacture, (2) the expiry of any extended exclusivity period in the relevant country (such as
orphan  drug  exclusivity,  pediatric  exclusivity,  new  chemical  entity  exclusivity,  or  other  exclusivity  granted  beyond  the  expiry  of  the  relevant  patent),  or  (3)  a  specific  time
period after the first commercial sale of the product in such country. In most countries, including the U.S., the patent term is generally 20 years from the earliest claimed filing
date of a non-provisional patent application in the applicable country, not taking into consideration any potential patent term adjustment that may be filed in the future or any
regulatory extensions that may be obtained. The royalty termination provision pursuant to (3) described above is shorter than 20 years and is the least likely cause of termination
of royalty payments.

The Onxeo license agreement does not have a pre-determined term, but expires on a product-by-product and country-by-country basis; that is, the agreement expires
with respect to a given product in a given country whenever our royalty payment obligations with respect to such product have expired. The agreement may also be terminated
early for cause if either we or Onxeo materially breach the agreement, or if either we or Onxeo become insolvent. We may also choose to terminate the agreement, either in its
entirety or as to a certain product and a certain country, by providing Onxeo with advance notice.

Grupo Español de Investigación en Sarcomas (“GEIS”)

In June 2019, we executed a clinical collaboration with GEIS for the development of camsirubicin in patients with advanced soft tissue sarcoma (“ASTS”). Following
completion of the Phase 1b clinical trial in the U.S. that we initiated in the third quarter of 2021 with the first patient dosed in October 2021, we continue to expect that GEIS
will sponsor and lead a multi-country, randomized, open-label Phase 2 clinical trial to evaluate camsirubicin head-to-head against doxorubicin, the current first-line treatment
for ASTS. We will provide study drug and supplemental financial support for the clinical trial. For quarter ended March 31, 2021, we incurred $0.3 million in expenses under
the  GEIS  agreement  and  other  clinical-related  expenses  including  clinical  material  manufacturing  and  database  management  expenses  in  support  of  the  then-planned  GEIS
Phase  2  camsirubicin  clinical  trial.  We  can  terminate  the  agreement  by  providing  GEIS  with  advance  notice,  and  without  affecting  our  rights  and  ownership  to  any  related
intellectual property or clinical data. In the second quarter of 2021, due to regulatory delays in Spain, we decided to conduct an open-label Phase 1b clinical trial of camsirubicin
in the U.S., therefore no expenses were incurred related to the GEIS collaboration beyond March 31, 2021.

XOMA Ltd.

Pursuant  to  a  non-exclusive  license  agreement  with  XOMA  Ltd.  for  the  humanization  technology  used  in  the  development  of  MNPR-101,  we  are  obligated  to  pay
XOMA Ltd. clinical, regulatory and sales milestones which could reach up to $14.925 million if we achieve all milestones for MNPR-101. The agreement does not require the
payment of sales royalties. There can be no assurance that we will achieve any milestones. As of March 10, 2023, we had not reached any milestones and had not been required
to pay XOMA Ltd. any funds under this license agreement.

Service Providers

In the normal course of business, we contract with service providers to assist in the performance of R&D, including drug product manufacturing, process development,
clinical and preclinical development, and G&A including financial strategy, audit, tax and legal support. We can elect to discontinue the work under these agreements at any
time.  We  could  also  enter  into  collaborative  research  and  development,  contract  research,  manufacturing  and  supplier  agreements  in  the  future,  which  may  require  upfront
payments and/or long-term commitments of cash.

Office Lease

We are currently leasing office space for our executive headquarters at 1000 Skokie Blvd., in the Village of Wilmette, Illinois for $4,238 per month through February

2024, and we anticipate that we will lease additional space in the future as we hire additional personnel.

Legal Contingencies

We are currently not, and to date have never been, a party to any adverse material legal proceedings.

Indemnification

In  the  normal  course  of  business,  we  enter  into  contracts  and  agreements  that  contain  a  variety  of  representations  and  warranties  and  provide  for  general
indemnification. Our exposure under these agreements is unknown because it involves claims that may be made against us in the future, but that have not yet been made. To
date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of
these indemnification obligations.

In accordance with our Second Amended and Restated Certificate of Incorporation, Amended and Restated Bylaws and the indemnification agreements entered into
with  each  officer  and  non-employee  director,  we  have  indemnification  obligations  to  our  officers  and  non-employee  directors  for  certain  events  or  occurrences,  subject  to
certain limits, while they are serving at our request in such capacity. There have been no claims to date. See Item 1A - “Risk Factors - We have limited the liability of and
indemnified our directors and officers.”

Item 9A. Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer have provided certifications filed as Exhibits 31.1 and 32.1, and 31.2, respectively. Such certifications should

(a) Management’s Annual Report on Internal Control over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting,  as  defined  in  Rule  13a15(f)  of  the  Securities
Exchange Act of 1934 (the “Exchange Act”). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of the
financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. This process includes
those policies and procedures (i) that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets,
(ii)  that  receipts  and  expenditures  are  being  made  only  in  accordance  with  authorizations  of  our  management  and  non-employee  directors,  (iii)  that  provide  reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements, and
(iv)  that  provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  GAAP.  Because  of  its
inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the internal control over financial
reporting to future periods are subject to risk that the internal control may become inadequate because of changes in conditions, or that the degree of compliance with policies or
procedures may deteriorate.

Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. Management based this assessment on the
criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework (2013). Management’s assessment
included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of our internal control over financial reporting.
Based on management’s assessment, management has concluded that, as of December 31, 2022, our internal control over financial reporting was effective.

(b) Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer,
of  the  effectiveness  of  our  disclosure  controls  and  procedures  as  of  December  31,  2022,  pursuant  to  Rules  13a15(e)  and  15d15(e)  under  the  Exchange Act.  Based  on  that
evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures, as of such date, were effective.

(c) Changes in Internal Control over Financial Reporting

We  have  concluded  that  the  consolidated  financial  statements  and  other  financial  information  included  in  this Annual  Report  on  Form  10-K  fairly  present  in  all

material respects our financial condition, results of operations and comprehensive loss and cash flows as of, and for, the periods presented.

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2022 that have materially affected, or are reasonably

likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

On  March  20,  2023,  our  Board  of  Directors  (“Board”)  increased  the  size  of  our  Board  from  five  to  six  members.  Simultaneously,  upon  recommendation  from  our
Corporate  Governance  &  Nominating  Committee,  our  Board  appointed  Kim  R.  Tsuchimoto  to  serve  on  our  Board  until  our  next  annual  meeting  of  stockholders.  Ms.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of Monopar Therapeutics Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Monopar Therapeutics Inc. and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, and the
related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows, for each of the two years in the period ended December 31, 2022,
and  the  related  notes  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material
respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period
ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  consolidated
financial statements based on our audits. 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 audits 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 consolidated 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 audits, 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 audits included performing procedures to assess the risks of material misstatement of the consolidated 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  consolidated  financial
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of
the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ BPM LLP

We have served as the Company’s auditor since 2015.

Note 1 - Nature of Business and Liquidity

Nature of Business

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

Monopar Therapeutics Inc. (“Monopar” or the ”Company”) is a clinical-stage biopharmaceutical company focused on developing proprietary therapeutics designed to extend
life or improve quality of life for cancer patients. Monopar currently has four compounds in development: 1) Validive® (clonidine hydrochloride mucobuccal tablet; clonidine
HCI MBT), a Phase 2b/3 clinical stage, first-in-class mucoadhesive buccal tablet for the prevention of radiation induced severe oral mucositis (“SOM”) in oropharyngeal cancer
patients; 2) camsirubicin (generic name for MNPR-201, GPX-150; 5-imino-13-deoxydoxorubicin), a Phase 1b clinical stage novel analog of doxorubicin engineered specifically
to retain anticancer activity while minimizing toxic effects on the heart; 3) MNPR-101 RIT and MNPR-101-Zr, a preclinical stage uPAR-targeted antibody being developed as a
radioimmunotherapeutic and companion diagnostic for advanced cancers; and 4) an early stage camsirubicin analog, MNPR-202, for various cancers. 

Liquidity

The Company has incurred an accumulated deficit of approximately $51.8 million as of December 31, 2022. To date, the Company has primarily funded its operations with the
net proceeds from the Company’s initial public offering of its common stock on Nasdaq, sales of its common stock in the public market through at-the-market sales agreements,
private placements of convertible preferred stock and of common stock and cash provided in the camsirubicin asset purchase transaction. Management estimates that currently
available cash will provide sufficient funds to enable the Company to meet its obligations at least through March 2024. The Company’s ability to fund its future operations,
including the continued clinical development of Validive and camsirubicin, is dependent upon its ability to execute its business strategy, to obtain additional funding and/or to
execute collaborative research agreements. There can be no certainty that future financing or collaborative research agreements will occur in the amounts required or at a time
needed to maintain operations, if at all.

The  coronavirus  disease  (“COVID-19”)  continues  to  affect  economies  and  business  around  the  world.  In  response  to  COVID-19  and  its  effects  on  clinical  trials,  in  2020
Monopar modified the original adaptive design Phase 3 clinical trial for its lead product candidate, Validive, to be a Phase 2b/3 clinical trial (“VOICE”) to better fit the types of
trials which can enroll sufficient required patients in the current environment. This modification allowed the Company to activate the VOICE clinical trial without requiring
near-term financing. To complete the VOICE clinical program, including, if required, completing a second Phase 3 confirmatory clinical trial, Monopar will require additional
funding in the millions or tens of millions of dollars (depending on if the Company has consummated a collaboration or partnership or neither for Validive), which it is planning
to pursue within the next 12 months. Due to many uncertainties, the Company is unable to estimate COVID-19’s financial impact or duration in light of global vaccine rollouts,
treatment  options  and  potential  surges  of  new  cases  from  current  or  future  COVID-19  variants  or  its  potential  impact  on  the  Company’s  current  clinical  trials,  including
COVID-19’s effect on drug candidate manufacturing, shipping, patient recruitment at clinical sites and regulatory agencies around the globe. 

The Russia-Ukraine war, and resulting sanctions against Russia and Russian entities or allies, have increased fuel costs and may cause shipping delays. The broader economic,
trade and financial market consequences are uncertain at this time, which may increase the cost of supplies for the Company’s clinical materials, may delay the manufacture of
its clinical materials, may increase costs of other goods and services, or make it more difficult or costly to raise additional financing, any of which could cause an adverse effect
on the Company’s clinical programs and on the Company’s financial condition.

Market  variables,  such  as  inflation  of  product  costs,  higher  capital  costs,  labor  rates  and  fuel,  freight  and  energy  costs,  as  well  as  geopolitical  events  could  likely  cause  the
Company to suffer significant increases in its operating and administrative expenses.

Note 2 - Significant Accounting Policies

Basis of Presentation

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

These consolidated financial statements include the financial results of Monopar Therapeutics Inc., its wholly-owned French subsidiary, Monopar Therapeutics, SARL, and its
wholly-owned Australian subsidiary, Monopar Therapeutics Australia Pty Ltd and have been prepared in accordance with accounting principles generally accepted in the U.S.
(“GAAP”) and include all disclosures required by GAAP for financial reporting. All intercompany accounts have been eliminated. The principal accounting policies applied in
the  preparation  of  these  consolidated  financial  statements  are  set  out  below  and  have  been  consistently  applied  in  all  periods  presented.  The  Company  has  been  primarily
involved in performing research activities, developing product candidates, and raising capital to support and expand these activities.

The accompanying consolidated financial statements contain all normal, recurring adjustments necessary to present fairly the Company’s consolidated financial position as of
December  31,  2022  and  2021,  the  Company’s  consolidated  results  of  operations  and  comprehensive  loss  and  the  Company’s  consolidated  cash  flows  for  the  years  ended
December 31, 2022 and 2021.

Functional Currency

The Company’s consolidated functional currency is the U.S. Dollar. The Company’s Australian subsidiary and French subsidiary use the Australian Dollar and European Euro,
respectively, as their functional currency. At each quarter-end, each foreign subsidiary’s balance sheets are translated into U.S. Dollars based upon the quarter-end exchange
rate, while their statements of operations and comprehensive loss and statements of cash flows are translated into U.S. Dollars based upon an average exchange rate during the
period.

Comprehensive Loss

Comprehensive loss represents net loss plus any income or losses not reported in the consolidated statements of operations and comprehensive loss, such as foreign currency
translations gains and losses and unrealized gains and losses on debt security investments that are reflected on the Company’s consolidated statements of stockholders’ equity.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and
liabilities,  disclosure  of  contingent  assets  and  liabilities,  and  reported  amounts  of  expenses  in  the  consolidated  financial  statements  and  accompanying  notes. Actual  results
could differ from those estimates. 

Going Concern Assessment

The Company applies Accounting Standards Codification 205-40 (“ASC 205-40”), Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, which
the Financial Accounting Standards Board (“FASB”) issued to provide guidance on determining when and how reporting companies must disclose going concern uncertainties in
their financial statements. ASC 205-40 requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the
date of issuance of the entity’s financial statements (or within one year after the date on which the financial statements are available to be issued, when applicable). Further, a
company must provide certain disclosures if there is “substantial doubt about the entity’s ability to continue as a going concern.” In February 2023, the Company analyzed its
cash requirements at least through March 2024 and has determined that, based upon the Company’s current available cash, the Company has no substantial doubt about its ability
to continue as a going concern.

Cash Equivalents

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

The  Company  considers  all  highly  liquid  investments  purchased  with  a  maturity  of  90  days  or  less  on  the  date  of  purchase  to  be  cash  equivalents.  Cash  equivalents  as  of
December 31, 2022 consisted of two money market accounts and U.S. Treasury Bills. Cash equivalents as of December 31, 2021 consisted of one money market account.

Investments

The Company considers all of its investments in debt securities (U.S. Government or Agencies), with maturities at the date of purchase from three months to one year to be
available-for-sale securities. These investments are recorded at fair value with the unrealized gains and losses reflected in accumulated other comprehensive income (loss) on the
Company’s  consolidated  balance  sheets.  Realized  gains  and  losses  from  the  sale  of  investments,  if  any,  are  determined  are  recorded  net  in  the  consolidated  statements  of
operations and comprehensive loss. The investments selected by the Company have a low level of inherent credit risk given they are issued by the U.S. government and any
changes in their fair value are primarily attributable to changes in interest rates and market liquidity. Investments as of December 31, 2022 consisted of U.S. Treasury Bills with
maturities of 91 days to one year. There were no investments as of December 31, 2021.

Prepaid Expenses

Prepayments are expenditures for goods or services before the goods are used or the services are received and are charged to operations as the benefits are realized. Prepaid
expenses  may  include  payments  to  development  collaborators  in  excess  of  actual  expenses  incurred  by  the  collaborator,  measured  at  the  end  of  each  reporting  period.
Prepayments also include insurance premiums, dues and subscriptions and software costs of $10,000 or more per year that are expensed monthly over the life of the contract,
which is typically one year. Prepaid expenses are reflected on the Company’s consolidated balance sheets as other current assets.

Leases

Lease agreements are evaluated to determine whether an arrangement is or contains a lease in accordance with ASC 842, Leases. Right-of-use lease assets and lease liabilities
are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The right-of-use lease asset on the Company’s
consolidated balance sheets includes any lease payments made and excludes lease incentives. The incremental borrowing taking into consideration the Company’s credit quality
and  borrowing  rate  for  similar  assets  is  used  in  determining  the  present  value  of  future  payments.  Lease  expense  is  recorded  as  general  and  administrative  expenses  on  the
Company’s consolidated statements of operations and comprehensive loss. ASC 842 was adopted by the Company on January 1, 2019. See Note 8 for discussion of operating
leases.

Concentration of Credit Risk

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

Financial  instruments  that  potentially  subject  the  Company  to  concentration  of  credit  risk  consist  of  cash  and  cash  equivalents.  The  Company  maintains  cash  and  cash
equivalents at two reputable financial institutions. As of December 31, 2022, the balance at one financial institution was in excess of the $ 250,000 Federal Deposit Insurance
Corporation (“FDIC”) insurable limit. The Company has not experienced any losses on its deposits since inception and management believes the Company is not exposed to
significant risks with respect to these financial institutions.

Fair Value of Financial Instruments

For  financial  instruments  consisting  of  cash  and  cash  equivalents,  investments,  accounts  payable,  accrued  expenses,  and  other  current  liabilities,  the  carrying  amounts  are
reasonable estimates of fair value due to their relatively short maturities.

The Company adopted ASC 820, Fair Value Measurements and Disclosures, as amended, which addresses the measurement of the fair value of financial assets and financial
liabilities.  Under  this  standard,  fair  value  is  defined  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  (i.e.,  the  “exit  price”)  in  an  orderly
transaction between market participants at the measurement date.

The  standard  establishes  a  hierarchy  for  inputs  used  in  measuring  fair  value  that  maximizes  the  use  of  observable  inputs  and  minimizes  the  use  of  unobservable  inputs  by
requiring that the most observable inputs be used when available. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on
market data obtained from independent sources. Unobservable inputs reflect a reporting entity’s pricing an asset or liability developed based on the best information available
under the circumstances. The fair value hierarchy consists of the following three levels: 

Level 1 – instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets.

Level 2 – instrument valuations are obtained from readily available pricing sources for comparable instruments.

Level 3 – instrument valuations are obtained without observable market values and require a high-level of judgment to determine the fair value.

Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each reporting period.
There were no transfers between Level 1, 2 or 3 of the fair value hierarchy during the years ended December 31, 2022, and 2021. The following table presents the assets and
liabilities recorded that are reported at fair value on our consolidated balance sheets on a recurring basis. No values were recorded in Level 2 or Level 3 at December 31, 2022,
and 2021.

(1) Cash equivalents as of December 31, 2022 represent the fair value of the Company’s investment in two money market accounts and U.S. Treasury Bills with maturities
at the date of purchase of less than 90 days. On December 31, 2021 cash equivalents represented the fair value of the Company’s investment in a money market account.

(2) Investments represents the fair value of the Company’s investment in U.S. Treasury Bills with maturities at the date of purchase from 90 days to one year.

Net Loss per Share

Net loss per share for the years ended December 31, 2022, and 2021, is calculated by dividing net loss by the weighted-average shares of common stock outstanding during the
period. Diluted net loss per share for the years ended December 31, 2022, and 2021 is calculated by dividing net loss by the weighted-average shares of the sum of a) weighted
average common stock outstanding (12,718,166  and 12,472,217 shares for the years ended December 31, 2022, and 2021, respectively) and b) potentially dilutive shares of
common  stock  (such  as  stock  options  and  restricted  stock  units)  outstanding  during  the  period. As  of  December  31,  2022,  and  2021,  potentially  dilutive  securities  included
stock-based  awards  to  purchase  up  to 1,915,600  and 1,655,451  shares  of  the  Company’s  common  stock,  respectively.  For  the  years  ended  December  31,  2022,  and  2021,
potentially dilutive securities are excluded from the computation of fully diluted net loss per share as their effect is anti-dilutive.

Research and Development Expenses

Research  and  development  (“R&D”)  costs  are  expensed  as  incurred.  Major  components  of  R&D  expenses  include  salaries  and  benefits  paid  to  the  Company’s  R&D  staff,
compensation  expenses  of  G&A  personnel  performing  R&D,  fees  paid  to  consultants  and  to  the  entities  that  conduct  certain  R&D  activities  on  the  Company’s  behalf  and
materials and supplies which were used in R&D activities during the reporting period.

Clinical Trials Accruals

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

The Company accrues and expenses the costs for clinical trial activities performed by third parties based upon estimates of the percentage of work completed over the life of the
individual study in accordance with agreements established with contract research organizations, service providers, and clinical trial sites. The Company estimates the amounts
to accrue based upon discussions with internal clinical personnel and external service providers as to progress or stage of completion of trials or services and the agreed upon fee
to be paid for such services. Costs of setting up clinical trial sites for participation in the trials are expensed immediately as R&D expenses. Clinical trial site costs related to
patient screening and enrollment are accrued as patients are screened/entered into the trial.

Collaborative Agreements

The Company and its collaborative partners are active participants in collaborative agreements and all parties would be exposed to significant risks and rewards depending on
the  technical  and  commercial  success  of  the  activities.  Contractual  payments  to  the  other  parties  in  collaboration  agreements  and  costs  incurred  by  the  Company  when  the
Company is deemed to be the principal participant for a given transaction are recognized on a gross basis in R&D expenses. Royalties and license payments are recorded as
earned.

During the years ended December 31, 2022, and 2021, no milestones were met, and no royalties were earned, therefore, the Company did not pay or accrue/expense any license
or royalty payments.

Licensing Agreements

The  Company  has  various  agreements  licensing  technology  utilized  in  the  development  of  its  product  or  technology  programs.  The  licenses  contain  success  milestone
obligations and royalties on future sales. During the years ended December 31, 2022, and 2021, no milestones were met, and no royalties were earned, therefore, the Company
did not pay or accrue/expense any license or royalty payments under any of its license agreements.

Patent Costs

The Company expenses costs relating to issued patents and patent applications, including costs relating to legal, renewal and application fees, as a component of general and
administrative expenses in its consolidated statements of operations and comprehensive loss.

Income Taxes

The Company uses  an  asset  and  liability  approach  for  accounting  for  deferred  income  taxes,  which  requires  recognition  of  deferred  income  tax  assets  and  liabilities  for  the
expected future tax consequences of events that have been recognized in its financial statements but have not been reflected in its taxable income. Estimates and judgments are
required in the calculation of certain tax liabilities and in the determination of the recoverability of certain deferred income tax assets, which arise from temporary differences
and carryforwards. Deferred income tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which
those tax assets and liabilities are expected to be realized or settled.

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

The Company regularly assesses the likelihood that its deferred income tax assets will be realized from recoverable income taxes or recovered from future taxable income. To
the extent that the Company believes any amounts are not “more likely than not” to be realized, the Company records a valuation allowance to reduce the deferred income tax
assets. In the event the Company determines that all or part of the net deferred tax assets are not realizable in the future, an adjustment to the valuation allowance would be
charged to earnings in the period such determination is made. Similarly, if the Company subsequently determines deferred income tax assets that were previously determined to
be unrealizable are now realizable, the respective valuation allowance would be reversed, resulting in an adjustment to earnings in the period such determination is made.

Internal Revenue Code Sections 382 and 383 (“Sections 382 and 383”) limit the use of net operating loss (“NOL”) carryforwards and R&D credits, after an ownership change.
To date, the Company has not conducted a Section 382 or 383 study, however, because the Company will continue to raise significant amounts of equity in the coming years,
the Company expects that Sections 382 and 383 will limit the Company’s usage of NOLs and R&D credits in the future.

ASC  740, Income  Taxes,  requires  that  the  tax  benefit  of  net  operating  losses,  temporary  differences,  and  credit  carryforwards  be  recorded  as  an  asset  to  the  extent  that
management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income
within the carryforward period. The Company has reviewed the positive and negative evidence relating to the realizability of the deferred tax assets and has concluded that the
deferred tax assets are not “more likely than not” to be realized. As a result, the Company recorded a full valuation allowance as of December 31, 2022, and 2021. U.S. Federal
R&D  tax  credits  from  2016  to  2019  were  utilized  to  reduce  payroll  taxes  in  future  periods  and  were  recorded  as  other  current  assets  (anticipated  to  be  received  within  12
months), on the Company’s consolidated balance sheets. The Company intends to maintain the valuation allowance until sufficient evidence exists to support its reversal. The
Company regularly reviews its tax positions. For a tax benefit to be recognized, the related tax position must be “more likely than not” to be sustained upon examination. Any
amount recognized is generally the largest benefit that is “more likely than not” to be realized upon settlement. The Company’s policy is to recognize interest and penalties
related to income tax matters as an income tax expense. For the years ended December 31, 2022, and 2021, the Company did not have any interest or penalties associated with
unrecognized tax benefits.

The Company is subject to U.S. Federal, Illinois and California state income taxes. In addition, the Company is subject to local tax laws of France and Australia. Tax regulations
within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. Monopar was originally formed as an
LLC in December 2014, then incorporated on December 16, 2015. The Company is subject to U.S. Federal, state and local tax examinations by tax authorities for the tax years
2015 through 2021. The Company does not anticipate significant changes to its current uncertain tax positions through December 31, 2022. The Company plans on filing its
U.S. Federal and state tax returns for the year ended December 31, 2022, prior to the extended filing deadlines in all jurisdictions.

Stock-Based Compensation

The  Company  accounts  for  stock-based  compensation  arrangements  with  employees,  non-employee  directors  and  consultants  using  a  fair  value  method,  which  requires  the
recognition of compensation expense for costs related to all stock-based awards, including stock option and restricted stock unit (“RSU”) grants. The fair value method requires
the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model or the closing stock price on the date of grant in the
case of RSUs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

Stock-based compensation expense for awards granted to employees, non-employee directors and consultants are based on the fair value of the underlying instrument calculated
using the Black-Scholes option-pricing model on the date of grant for stock options and using the closing stock price on the date of grant for RSUs and recognized as expense
on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment,
including estimating the future stock price volatility and expected terms. The expected volatility rates are estimated based on the Company’s historical actual volatility over the
two-year period from its initial public offering on December 18, 2019 through December 31, 2021. Forfeitures only include known forfeitures to-date as the Company accounts
for forfeitures as they occur due to a limited history of forfeitures. The expected term for options granted to date is estimated using the simplified method. The Company has not
paid dividends and does not anticipate paying a cash dividend in the future vesting period and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is
based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Note 3 - Investments

As of December 31, 2022 the Company had two money market accounts and available-for-sale investments with contractual maturities of one year or less as follows:

Note 7 – Income Taxes

ASC  740, Income  Taxes,  requires  that  the  tax  benefit  of  net  operating  losses,  temporary  differences,  and  credit  carryforwards  be  recorded  as  an  asset  to  the  extent  that
management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income
within the carryforward period. The Company has reviewed the positive and negative evidence relating to the realizability of the deferred tax assets and has concluded that the
deferred  tax  assets  are  not  “more  likely  than  not”  to  be  realized.  The  valuation  allowance  increased  by  approximately  $3,421,000  and  $2,500,000  during  the  years  ended

As of December 31, 2022, Company had total federal net operating loss carryforwards of approximately $12,428,000, which will begin to expire in 2035. Losses generated after
2017 will be carried forward indefinitely. At December 31, 2022, the Company had state net operating loss carryforwards of approximately $ 12,457,000 which will begin to
expire in 2027.

As of December 31, 2022, the Company had federal and state tax credits of $1,426,000 and $183,000, respectively. The federal credits expire beginning after the year 2035 and
the state credits began to expire in 2023.

The Tax Reform Act of 1986 limits the use of net operating carryforwards and R&D credits in certain situations where changes occur in the stock ownership of a company. In
the event the Company has had a change in ownership, utilization of the carryforwards and R&D credits could be limited. The Company has not performed a net operating loss
or R&D credit utilization study to date.

The Company accounts for uncertain tax positions in accordance with ASC 740-10, “Accounting for Uncertainty in Income Taxes.” ASC 740-10 prescribes a comprehensive
model for the recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken or are expected to be taken on a
tax return. It is Company’s policy to include penalties and interest expense related to income taxes as an income tax expense.

offset  by  the  reversal  of  related  deferred  tax  assets  which  are  subject  to  a  full  valuation  allowance.  The  Company  anticipates  that  no  material  amounts  of  unrecognized  tax
benefits will be settled within 12 months of the reporting date. As of December 31, 2022, the Company had no accrued interest or penalties recorded related to uncertain tax
positions.

The Company files U.S. federal, California and Illinois state tax returns. Company is subject to California state minimum franchise taxes. All tax returns will remain open for
examination by the federal and state taxing authorities for three and four years, respectively, from the date of utilization of any net operating loss carryforwards or R&D credits.
In addition, due to the operations in certain foreign countries, the Company became subject to local tax laws of such countries. Nonetheless, as of December 31, 2022, due to the
insignificant expenditures in such countries, there was no material tax effect to the Company’s 2022 consolidated financial statements.

On  December  22,  2017,  the  Tax  Cuts  and  Jobs Act  of  2017  (“TCJA”)  was  enacted.  On  January  1,  2022,  a  provision  of  the  TCJA  went  into  effect  which  requires  the
capitalization  of  research  and  development  costs  in  the  year  incurred  and  requires  taxpayers  to  amortize  such  costs  over  five  years  and  15  years  for  domestic  and  foreign
expense, respectively. The Company evaluated the impact of the TCJA and prepared the provision by following the treatment of research and development expenditures for tax
purposes under Section 174.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 8 – Commitments and Contingencies

License, Development and Collaboration Agreements

Onxeo S.A.

In June 2016, the Company executed an option and license agreement with Onxeo S.A. (“Onxeo”), a public French company, which gave Monopar the exclusive option to
license (on a world-wide exclusive basis) Validive to pursue treating severe oral mucositis in patients undergoing chemoradiation treatment for head and neck cancers. The pre-
negotiated Onxeo license agreement for Validive as part of the option agreement includes clinical, regulatory, developmental and sales milestones that could reach up to $108
million if the Company achieves all milestones, and escalating royalties on net sales from 5% to 10%. On September 8, 2017, the Company exercised the license option, and
therefore paid Onxeo the $1 million fee under the option and license agreement.

Under the agreement, the Company is required to pay royalties to Onxeo on a product-by-product and country-by-country basis until the later of (1) the date when a given
product is no longer within the scope of a patent claim in the country of sale or manufacture, (2) the expiry of any extended exclusivity period in the relevant country (such as
orphan  drug  exclusivity,  pediatric  exclusivity,  new  chemical  entity  exclusivity,  or  other  exclusivity  granted  beyond  the  expiry  of  the  relevant  patent),  or  (3)  a  specific  time
period after the first commercial sale of the product in such country. In most countries, including the U.S., the patent term is generally 20 years from the earliest claimed filing
date of a non-provisional patent application in the applicable country, not taking into consideration any potential patent term adjustment that may be filed in the future or any
regulatory extensions that may be obtained. The royalty termination provision pursuant to (3) described above is shorter than 20 years and is the least likely cause of termination
of royalty payments.

The  Onxeo  license  agreement  does  not  have  a  pre-determined  term,  but  expires  on  a  product-by-product  and  country-by-country  basis;  that  is,  the  agreement  expires  with
respect to a given product in a given country whenever the Company’s royalty payment obligations with respect to such product have  expired.  The  agreement  may  also  be
terminated early for cause if either the Company or Onxeo materially breach the agreement, or if either the Company or Onxeo  become  insolvent.  The  Company  may  also
choose to terminate the agreement, either in its entirety or as to a certain product and a certain country, by providing Onxeo with advance notice.

The Company is internally developing Validive and has its ongoing VOICE clinical trial, which, if successful, may allow the Company to apply for marketing approval within
the  next  several  years.  The  Company  will  need  to  raise  significant  funds  or  enter  into  a  collaboration  partnership  to  support  the  further  development,  including  potential
commercialization of Validive. As of December 31, 2022, the Company had not reached any of the pre-specified milestones and has not been required to pay Onxeo any funds
under this license agreement other than the $1 million one-time license fee.

Grupo Español de Investigación en Sarcomas (“GEIS”)

In June 2019, the Company executed a clinical collaboration agreement with GEIS for the development of camsirubicin in patients with advanced soft tissue sarcoma (“ASTS”).
Following completion of the Phase 1b clinical trial in the U.S. that Monopar initiated in the third quarter of 2021 with the first patient dosed in October 2021, the Company
continues to expect that GEIS will sponsor and lead a multi-country, randomized, open-label Phase 2 clinical trial to evaluate camsirubicin head-to-head against doxorubicin,
the current first-line treatment for ASTS. The Company will provide study drug and supplemental financial support for the clinical trial. For three months ended March 31,
2021,  Monopar  incurred  $0.3  million  in  expenses  under  the  GEIS  agreement  and  other  clinical-related  expenses  including  clinical  material  manufacturing  and  database
management expenses in support of the then-planned GEIS Phase 2 camsirubicin

clinical  trial.  The  Company  can  terminate  the  agreement  by  providing  GEIS  with  advance  notice,  and  without  affecting  the  Company’s  rights  and  ownership  to  any  related
intellectual  property  or  clinical  data.  In  the  second  quarter  of  2021,  due  to  regulatory  delays  in  Spain,  Monopar  decided  to  conduct  an  open-label  Phase  1b  clinical  trial  of
camsirubicin in the U.S., therefore no expenses were incurred related to the GEIS collaboration beyond March 31, 2021. 

 XOMA Ltd.

The intellectual property rights contributed by Tactic Pharma to the Company included the non-exclusive license agreement with XOMA Ltd. for the humanization technology
used in the development of MNPR-101. Pursuant to such license agreement, the Company is obligated to pay XOMA Ltd. clinical, regulatory and sales milestones for MNPR-
101 that could reach up to $14.925 million if the Company achieves all milestones. The agreement does not require the payment of sales royalties. There can be no assurance
that the Company will reach any milestones under the XOMA agreement. As of December 31, 2022, the Company had not reached any milestones and has not been required to
pay XOMA Ltd. any funds under this license agreement.   

Operating Leases

The Company is currently leasing office space for its executive headquarters at 1000 Skokie Blvd., in the Village of Wilmette, Illinois for $4,238 per month. In February 2022,
the Company entered into a 24-month lease for 1,202 square feet of the office space for $2,379 per month. In May 2022, the Company entered into a 22-month lease for 939
square feet of additional office space for $1,859 per month. 

As of December 31, 2022, in accordance with ASC 842, Leases, the two leases were recorded as an operating lease right-of-use (“ROU”) asset and a lease liability included in
accounts payable, accrued expenses and other current liabilities, and non-current operating lease liability on the Company’s consolidated balance sheets. The initial ROU asset
and associated liability is equal to the present value of the minimum lease payments. Since the rate implicit in the lease is rarely readily determinable, the Company applied an
incremental borrowing rate taking into consideration our credit quality and borrowing rate for similar assets. The lease terms used to calculate the ROU asset and related lease
liability does not include an option to extend but does include an option to terminate the lease. Lease costs for operating leases are recognized on a straight-line basis over the
expected lease term and recorded as general and administrative expenses on the Company’s consolidated statements of operations and comprehensive loss. Amortization of the
ROU  asset  commenced  on April  1,  2022,  and  June  1,  2022,  for  the  two  operating  leases,  respectively.  No  ROU  asset  or  lease  liability  was  recorded  in  2021  as  the  lease
obligation was less than one year.

Legal Contingencies

MONOPAR THERAPEUTICS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2022

The Company may be subject to claims and assessments from time to time in the ordinary course of business. No claims have been asserted to date. 

Indemnification

In  the  normal  course  of  business,  the  Company  enters  into  contracts  and  agreements  that  contain  a  variety  of  representations  and  warranties  and  provide  for  general
indemnification. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but that have not
yet been made. To date, the Company has not paid any claims nor been required to defend any action related to its indemnification obligations. However, the Company may
record charges in the future as a result of future claims against these indemnification obligations. 

In accordance with its second amended and restated certificate of incorporation, amended and restated bylaws and the indemnification agreements entered into with each officer
and non-employee director, the Company has indemnification obligations to its officers and non-employee directors for certain events or occurrences, subject to certain limits,
while they are serving at the Company’s request in such capacities. There have been no indemnification claims to date.

 EXHIBIT 4.1

We have the authority to issue 40,000,000 shares of Common Stock, $0.001 par value.

DESCRIPTION OF REGISTERED SECURITIES

Common Stock

Voting Rights

The holders of shares of our common stock are entitled to one vote per share for the election of directors and on all other matters submitted to a vote of stockholders.
Shares of our common stock do not have cumulative voting rights. The election of our Board of Directors (“Board”) is decided by a plurality of the votes cast at a meeting of
our stockholders by the holders of stock entitled to vote in the election.

Dividends

Holders of our common stock are entitled to receive such dividends as may be declared by our Board out of funds legally available therefor.

Liquidation

Upon our dissolution and liquidation, holders of our common stock are entitled to a ratable share of our net assets remaining after payments to our creditors.

Rights and Preferences

Our stockholders have no preemptive rights to acquire additional shares of our common stock or other securities. The shares of our common stock are not subject to

redemption.

Preferred Stock

We have no preferred stock authorized or outstanding.

Anti-Takeover Provisions

Delaware Law

We are subject to Section 203 of the Delaware General Corporation Law. 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 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.

Authorized but Unissued Shares

The  authorized  but  unissued  shares  of  our  common  stock  are  available  for  future  issuance  without  stockholder  approval,  subject  to  any  limitations  imposed  by  the
listing standards of any exchange on which our shares are listed. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee
benefit plans. The existence of authorized but unissued and unreserved common stock could make more difficult or discourage an attempt to obtain control of us by means of a
proxy contest, tender offer, merger or otherwise.

Election of Director by Plurality of Shares; Vacancies

Our Amended and Restated By-laws provide that directors will be elected by a plurality of votes cast by the shares present in person or by proxy at a meeting of the
stockholders and entitled to vote thereon, a quorum being present at such meeting. There is no cumulative voting, meaning that Directors may be elected with a vote of holders
of less than a majority of the outstanding common stock.

Our Amended and Restated By-laws also provide that vacancies occurring on our Board may be filled by the affirmative votes of a majority of the remaining members
of our Board or by the sole remaining director, and not by our stockholders. Such provisions in our corporate organizational documents and under Delaware law may prevent or
frustrate attempts by our stockholders to change our management or hinder efforts to acquire a controlling interest in us. The inability to make changes to our Board could
prevent or discourage an attempt to take control of the Company by means of a proxy contest, tender offer, merger or otherwise.

Special Meeting of Stockholders; Advance Notice Requirements for Stockholder Proposals and Director Nominations; Stockholder Action

Our Amended and Restated By-laws provide that, except as otherwise required by law, special meetings of the stockholders can only be called by our Board.

1

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Stockholders at a special meeting may only consider matters set forth in the notice of the meeting. These provisions could have the effect of delaying until the next stockholder
meeting stockholder actions that may be favored by the holders of a majority of our outstanding voting securities.

Super Majority Voting

The General Corporation Law of the State of Delaware 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 Amended and Restated By-laws may be amended or repealed by a majority vote of our Board or the affirmative vote of the holders of at least a majority of the votes that
all our stockholders would be entitled to cast in any election of Directors.

Registration Rights

We  are  subject  to  an  agreement  with  TacticGem,  LLC  (“TacticGem”),  our  largest  stockholder,  which  obligates  us  to  file  a  Form  S-3  or  other  appropriate  form  of
registration statement covering the resale of any of our Common Stock by TacticGem, or its members Gem Pharmaceuticals, LLC, or Tactic Pharma, LLC, upon direction by
TacticGem at any time after we have been subject to the reporting requirements of the 1934 Act for at least twelve months (the “Initial Holding Period”).. We are required to
use  our  best  efforts  to  have  such  registration  statement  declared  effective  as  soon  as  practical  after  it  is  filed.  In  the  event  that  such  registration  statement  for  resale  is  not
approved by the SEC, and TacticGem submits a written request, we are required to prepare and file a registration statement on Form S-1 registering such Common Stock for
resale and to use our best efforts to have such registration statement declared effective as soon as practical thereafter. After registration, pursuant to these rights, these shares
will become freely tradable without restriction under the Securities Act other than pursuant to restrictions on affiliates under Rule 144.

Listing

Our common stock is listed on the Nasdaq Capital Market under the symbol “MNPR.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is VStock Transfer, LLC (“VStock”). VStock’s address is 18 Lafayette Place, Woodmere, NY 11598.
