Risk Factors Summary

The risk factors summarized below could materially harm our business, operating results, and/or financial condition, impair our future prospects 
and/or cause the price of our common stock to decline. These risks are discussed more fully in the section titled "Risk Factors." Material risks that may 
affect our business, financial condition, results of operations, and trading price of our common stock include the following:

• We have incurred significant losses since our inception. We expect to incur losses over the next several years and may never achieve or maintain 

profitability.  

• We will need substantial additional funding to meet our financial obligations and to pursue our business objectives. If we are unable to raise 
capital when needed, we could be forced to delay, reduce or altogether cease our drug development programs or commercialization efforts. 

•

•

•

Our efforts are focused on the development of product candidates for treatment of eye disease through suprachoroidal injection and partnering 
with companies who can leverage our SCS Microinjector to deliver their ophthalmic product candidates to the suprachoroidal space, or SCS. 
Suprachoroidal injection is a novel approach and may fail to achieve and sustain market acceptance. 

If we are unable to obtain regulatory approval for, and commercialize either on our own or with a third party, CLS-AX or our other product 
candidates, or if we experience significant delays in doing so, our business may be harmed. 

Clinical drug development involves a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience 
delays in completing, or ultimately be unable to complete, the development of our product candidates. 

• We have entered into, and intend to continue to enter into, collaborations with third parties for the development and commercialization of 

XIPERE. In addition, we may seek commercialization partners for our product candidates. If those collaborations are not successful, we may not 
be able to capitalize on the market potential of XIPERE and our product candidates. 

•

If we are unable to obtain and maintain patent protection for our technology and product candidates, or if our licensors are unable to obtain and 
maintain patent protection for the technology or product candidates that we license from them, or if the scope of the patent protection obtained is 
not sufficiently broad, our competitors could develop and commercialize technology and drugs similar or identical to ours, and our ability to 
successfully commercialize our technology and product candidates may be impaired.

ITEM 1. BUSINESS

Overview

PART I

We are a biopharmaceutical company focused on revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space, or 

SCS. Our novel SCS injection platform, utilizing our proprietary SCS Microinjector, enables an in-office, repeatable, non-surgical procedure for the 
targeted and compartmentalized delivery of a wide variety of therapies to the macula, retina or choroid to potentially preserve and improve vision in 
patients with sight-threatening eye diseases. Our SCS injection platform can be used in conjunction with existing drugs designed for delivery to the SCS, 
novel therapies and future therapeutic innovations. We believe our proprietary suprachoroidal administration platform has the potential to become a 
standard for delivery of therapies intended to treat chorioretinal diseases.

We are leveraging our SCS injection platform by building an internal research and development pipeline targeting retinal diseases and by creating 
external collaborations with other companies. We are developing our own pipeline of small molecule product candidates for administration via our SCS 
Microinjector, and we also strategically partner with companies developing other ophthalmic therapeutic innovations to be administered using our SCS 
injection technology. Our first product, XIPERE (triamcinolone acetonide injectable suspension) for suprachoroidal use, was approved by the U.S. Food 
and Drug Administration, or the FDA, in October 2021. Approval of XIPERE was a significant milestone for us as it is the first approved therapeutic 
delivered into the SCS, the first commercial product developed by us and the first therapy for macular edema associated with uveitis.

We believe that we are creating a broad therapeutic platform for developing product candidates to treat serious eye diseases.

Our Suprachoroidal Space (SCS) Injection Platform

Our suprachoroidal injection platform is a novel, patented approach for delivering pharmacotherapy to the back of the eye via the SCS. When fluid 

is injected between the choroid and sclera, the elasticity of the SCS allows the fluid to migrate and spread spherically toward the posterior regions of the 
eye where it is absorbed into adjacent tissue. Our proprietary SCS microinjector is able to precisely administer drugs into the SCS utilizing a needle that is 
approximately one millimeter in length. This non-surgical method of administration facilitates more targeted delivery of therapeutic agents to chorioretinal 
structures and can be accomplished in an in-office setting. The suprachoroidal injection procedure is depicted in the picture below.

With suprachoroidal injections, product candidates are more directly administered to the retina and choroid, limiting exposure to non-target tissues 

as compared to other ocular drug administration techniques. Furthermore, a natural pressure gradient between the intraocular pressure, or IOP, and the SCS 
pressure drives suprachoroidal injectates posteriorly towards the macula, which facilitates treatment of macular disorders with this office-based approach, 
without the need for an intraocular catheter or other surgical techniques. In contrast, intravitreal injections, the current standard for delivery of many drugs 
for eye diseases, rely on diffusion of drug outward from the vitreous, a jelly-like substance that occupies the central portion of the eye, to the retina and 
choroid. This diffusion can result in lower concentrations of drug in these targeted areas and the drug spreading to unintended parts of the eye, potentially 
causing significant side effects. We believe treatment of eye disease via suprachoroidal injection may provide a number of benefits, including a non-
surgical procedure, lower frequency of administration, limited exposure to non-targeted tissues, faster onset of therapeutic effect and an improved safety 
profile.

Table of Contents

On January 1, 2024, a permanent Category 1 Current Procedural Terminology, or CPT, code was granted for the suprachoroidal injection of 
pharmacologic agents. We believe the Category 1 code may facilitate better access, insurance coverage and adoption of the suprachoroidal injection 
procedure.

Our extensive patent portfolio provides us with the right to develop and commercialize pharmacological agents for treatment of eye diseases via 

suprachoroidal injection. We believe this proprietary method of administration has the potential to become the standard for the delivery of therapies 
intended to treat retinal and choroidal diseases. Our intellectual property portfolio consists of 28 issued U.S. patents and more than 80 European and 
international patents broadly directed to the use of the SCS Microinjector, administration of any drug into the SCS by injection, as well as XIPERE and our 
product candidates.

Our SCS Microinjector

Our proprietary SCS Microinjector can be used to inject a wide variety of therapies into the SCS, including our internally developed and our 
collaborators’ drug candidates. Our SCS Microinjector provides targeted delivery to potentially improve efficacy and compartmentalization of medication 
to reduce or eliminate toxic effects on non-diseased cells. Suprachoroidal injection enables the rapid dispersion of medicine to the back of the eye, offering 
the potential for the medicine to act longer and minimize harm to the surrounding healthy parts of the eye.

Our SCS Microinjector has been used in thousands of suprachoroidal injections in our clinical trials and the clinical trials of our partners. It has been 

commercially accepted by retinal physicians following the launch of XIPERE in the United States by Bausch + Lomb with over 1,200 retinal physicians 
trained to date.  Suprachoroidal injections using our SCS Microinjector have demonstrated a clinical safety profile comparable to intravitreal injections.

The SCS Microinjector, shown in the picture below, is composed of a syringe and two 30-gauge hollow microneedles of varying lengths, each 

approximately one millimeter, within a custom-designed hub that optimizes insertion and suprachoroidal administration of drugs.

Current intravitreal injections are performed in a procedure similar to that of suprachoroidal injections, except that the hypodermic needles and 

syringes used in intravitreal injection procedures are designed so that the needle penetrates through all of the layers of the eye and drug is injected into the 
vitreous cavity. Intravitreal injections are typically performed using a needle that is approximately five millimeters in length, or five times the length of our 
microneedle. Using a needle of this length, the physician penetrates past the sclera, choroid and retina until reaching the vitreous and does not receive any 
tactile feedback as to when the needle reaches one of the layers between the sclera and the vitreous. 

By contrast, our SCS Microinjector is designed to inject drug into the SCS. This suprachoroidal injection is designed to be carried out under local 

anesthesia, perpendicular to the sclera, at a site similar to an intravitreal injection. Once the microneedle 

6

 
Table of Contents

penetrates the sclera and reaches the SCS, the boundary between the sclera and the choroid, the open bevel of the needle releases the drug between these 
two layers. Once drug is injected into the SCS, it spreads to the back of the eye, due to a natural pressure gradient between the IOP and the SCS pressure, 
precisely targeting the cells of interest without the need for intraocular catheters or other surgical techniques. 

Our Pipeline 

We have research capabilities focused on developing proprietary therapeutic formulations to utilize with our SCS Microinjector. Our current 
internal research and development initiatives are focused on small molecules to address serious diseases that affect the back of the eye. In addition to 
growing our internal pipeline, we are also focused on strategically collaborating with other companies to provide access to the suprachoroidal space 
through the use of our SCS Microinjector. 

The current development status of our pipeline of internal product candidates and external collaborations is summarized in the chart below: 

Clinical Development Pipeline

We are building a clinical development pipeline focused on small molecules.  Our first product, XIPERE, was approved by the FDA in October 

2021. The XIPERE approval supports our approach both clinically and preclinically to advance small molecule suspensions delivered into the SCS. 

Our most advanced clinical development product candidate is a proprietary suspension of axitinib, a tyrosine kinase inhibitor, or TKI, for 
suprachoroidal injection, which we refer to as CLS-AX. We have completed OASIS, a Phase 1/2a clinical trial in patients with neovascular age-related 
macular degeneration, commonly referred to as wet AMD. In December 2023, we completed the randomization of participants for ODYSSEY, our Phase 
2b clinical trial of CLS-AX. We expect to report topline data from the ODYSSEY trial in the third quarter of 2024.

CLS-AX (axitinib injectable suspension)

CLS-AX, our most advanced product candidate, is our proprietary suspension of the TKI axitinib for suprachoroidal injection delivered via our SCS 
Microinjector. CLS-AX is an inhibitor of vascular endothelial growth factor receptor-1, -2 and -3 that we believe may benefit patients as a potential longer 
duration maintenance therapy alongside other anti-VEGF therapies. We are developing CLS-AX for administration to the SCS as a long-acting therapy for 
wet AMD, a retinal degenerative disease that causes a progressive loss of central vision. 

AMD is the leading cause of irreversible blindness in adults over 55 years old in developed countries. Approximately 11 million individuals in the 

United States are affected with AMD, with a global prevalence of 170 million. Aging is the greatest risk factor; 

7

 
Table of Contents

therefore, the United States prevalence of AMD is anticipated to increase to 22 million by 2050, while the global prevalence is expected to increase to 288 
million by 2040. An estimated 10% to 15% of people with AMD will develop the wet form, which refers to the advanced neovascular stage of the disease 
in which blood vessels leak blood and fluid into the macula and damage photoreceptor cells. Wet AMD often progresses rapidly and causes substantial loss 
of central vision if left untreated. Current wet AMD therapy has a ceiling of efficacy as increased dosage or more intense regimens yield limited or no 
additional visual benefit and require adherence to a regimen of frequent injections. This treatment burden is further highlighted by recent large “real-world” 
retrospective studies of wet AMD which underscore the difficulty in adhering to regimens. These real-world studies demonstrate that patients are 
undertreated, receiving only 6 to 7 injections per year on average, resulting in mean improvement of only one to three letters in visual acuity after one year 
of treatment. The current anti-VEGF market for the treatment of retinal diseases consists of several drugs that generated aggregate 2020 sales of 
approximately $14.3 billion globally. 

Axitinib is currently approved to treat renal cell cancer. Because it is a well-characterized small molecule instead of a novel complex biologic, we 

believe there is potential for less immune response and inflammation compared to some new, contemporary biologic agents. Also, compared to other TKIs, 
axitinib has shown better biocompatibility with ocular cells, including retinal pigment epithelial cells, which may potentially translate to safety benefits. 
Other TKIs have shown biologic effect in wet AMD clinical trials when delivered systemically, topically and intravitreally.  However, each of these routes 
of administration have been associated with off-target effects. Consequently, a limitation of TKIs may be associated with the delivery of the drug and not a 
result of the mechanism of action. Importantly, we believe that administration of CLS-AX to the SCS using our SCS Microinjector, may minimize the 
occurrence of related adverse events, such as vitreous floaters, "snow globe" effect or corneal off-target effects seen with other TKI administration 
techniques. 

With its broad VEGF blockade, we believe axitinib may have efficacy advantages over existing retinal therapies, which predominantly focus on 

VEGF-A blockade and may upregulate other forms of VEGF. Axitinib achieves pan-VEGF blockade by acting at a different level of the angiogenesis 
cascade, directly inhibiting VEGF receptors-1, -2, and -3 with high potency and specificity. In preclinical studies, axitinib was observed to be greater than 
ten times more potent than other TKIs. In multiple preclinical animal studies conducted by independent investigators, axitinib has inhibited corneal, retinal 
and choroidal angiogenesis.  In addition, in preclinical models, axitinib more effectively inhibited and regressed experimental corneal neovascularization 
than other TKIs.

In our internal preclinical studies, CLS-AX delivered through suprachoroidal injection was well tolerated and showed durability over several 
months. This could lead to a longer lasting, highly effective treatment that may reduce the number of treatments and visits required for wet AMD patients 
to achieve optimal results. These studies have also demonstrated up to eleven times higher drug levels in affected tissues versus intravitreal administration 
of the same dose of axitinib. Therefore, suprachoroidal delivery of CLS-AX has the potential to compartmentalize therapy away from unaffected tissues for 
potential safety benefits and target the affected chorioretinal tissue layers for potential efficacy benefits. 

In August 2020, we announced that the FDA had accepted our Investigational New Drug application, or IND, for CLS-AX. In January 2021, we 

announced the enrollment of our first participant in OASIS, a Phase 1/2a clinical trial of CLS-AX in participants with wet AMD. OASIS was an open-
label, dose-escalation clinical trial to assess the safety and tolerability of single doses of CLS-AX administered through suprachoroidal injection following 
two or more prior treatments with aflibercept, an intravitreal anti-VEGF agent, dosed at screening. All participants were highly treatment-experienced wet 
AMD participants with active disease at screening. The primary endpoint for the trial assessed the safety and tolerability of CLS-AX for the three months 
following the administration of CLS-AX, and secondary endpoints evaluated the pharmacokinetics, visual function, ocular anatomy and the need for 
additional treatment with intravitreal aflibercept during the three- and six-month periods.

Participant inclusion criteria for enrollment in OASIS included: active subfoveal choroidal neovascularization secondary to AMD; two or more anti-

VEGF treatments with a meaningful response in the four months preceding the screening visit; and a best corrected visual acuity, or BCVA, score of ≥ 20 
letters (20/400) and ≤ 75 letters (20/32) with < 5 letters change between screening and baseline to ensure patient stability after anti-VEGF treatment. 
Participants were assessed at weeks four, eight and twelve. Participants were assessed for additional therapy if they experienced any of the following: (1) 
loss of 10 or more letters in BCVA compared to the best prior study-assessed BCVA in the study eye that is attributed to intra- or sub-retinal fluid observed 
by the investigator; (2) increase in central subfield retinal thickness greater than 75 microns from baseline at visit 2 in the study eye; or (3) presence of 
vision-threatening hemorrhage due to AMD in the study eye. The trial consisted of four cohorts at the following doses of CLS-AX delivered via 
suprachoroidal injection: Cohort 1 at 0.03 mg; Cohort 2 at 0.1 mg; Cohort 3 at 0.5 mg; Cohort 4 at 1.0 mg. In January 2021, we announced that the first 
participants had been enrolled in OASIS. In December 2021, we announced that the primary endpoints were met in Cohorts 1 and 2. CLS-AX was well 
tolerated with no serious adverse events; there were no treatment emergent adverse events related to aflibercept, CLS-AX or the suprachoroidal injection 
procedure, no dispersion of drug into the vitreous, and no adverse events related to IOP, inflammation or vasculitis. In July 2022, we completed patient 
enrollment of OASIS and also completed dosing in Cohort 3 in which each patient received a dose of 0.5 mg, and in Cohort 4 in which each patient 
received a dose of 1.0 mg.

Table of Contents

In the four OASIS cohorts we enrolled a total of 27 participants. All participants were highly treatment-experienced wet AMD participants with 

active disease at screening. These four cohorts allowed us to collect more CLS-AX patient data to help guide our selection of the most appropriate dosing 
protocol for ODYSSEY, our Phase 2b clinical trial of CLS-AX for the treatment of wet AMD. 

Participants in Cohorts 2, 3, and 4 who elected to participate in an extension study were followed for an additional 3 months. In November 2022, we 

reported positive results that included final three-month data from Cohorts 3 and 4, and interim data from the extension study. CLS-AX demonstrated a 
positive safety profile in all four cohorts. There were no serious adverse events and no treatment emergent adverse events related to aflibercept, CLS-AX, 
or the suprachoroidal injection procedure. There were also no dose limiting toxicities. There were no adverse events related to inflammation, vasculitis or 
vascular occlusion, and there were no vitreous “floaters” or dispersion of CLS-AX into the vitreous.  

In Cohorts 3 and 4, the data showed favorable durability with a meaningful reduction in treatment burden at the 3-month endpoint and to date in the 
extension study. Of the 16 participants in Cohorts 3 and 4, at the 3-month endpoint, 69% did not receive additional therapy, 92% did not receive additional 
therapy per protocol criteria, and there was at least a 73% reduction in treatment burden from the average monthly injections in the three months before 
CLS-AX administration.  Of the 12 participants in the extension study, based on interim data as of October 27, 2022, 88% (7/8) of participants did not 
receive additional therapy to the 5-month endpoint and 75% (3/4) of participants did not receive additional therapy to the 6-month endpoint.  Further, in the 
extension study, there was at least a 90% reduction in treatment burden from the average monthly injections in the six months before CLS-AX 
administration. In Cohorts 3 and 4, CLS-AX also showed an observable biologic effect with stable mean BCVA, stable mean central subfield thickness, or 
CST, and anatomical signs of TKI biologic effect observed on Optical Coherence Tomography, or OCT, images.

On February 2, 2023, we announced positive results from the completed OASIS extension study.

CLS-AX was well-tolerated and demonstrated a favorable safety profile across all cohorts in both the three-month dose-escalation portion (n=27) 

and the extension study (n=14). No serious adverse events, treatment emergent adverse events related to study or dose limiting toxicities were observed. In 
addition, there were no adverse events related to inflammation, vasculitis or vascular occlusion, no vitreous “floaters” or dispersion of CLS-AX into the 
vitreous and no retinal detachments, endophthalmitis or adverse events related to IOP.

The full extension data for Cohorts 3 and 4 (n=12) showed promising durability, with a 77% - 85% reduction in treatment burden observed 
compared to the average monthly injections in the six months before CLS-AX administration. The table below details the length of time the participants 
went without additional therapy:

Duration Without Additional Therapy
≥ 3 Months
≥ 4 Months
≥ 6 Months
> 6 Months

Number of Participants (n=12)
11/12 (92%)
10/12 (83%)
8/12 (67%)
6/12 (50%)

In Cohorts 3 and 4 of the extension study, CLS-AX showed signs of biologic effect with stable mean BCVA and stable mean  CST to the six-month 

timepoint. On OCT images, anatomical signs of TKI biologic effect were observed in anti-VEGF treatment experienced sub-responders. 

ODYSSEY Phase 2b Clinical Trial 

Based on the results from the OASIS trial, we are conducting a randomized, controlled, double-masked, Phase 2b clinical trial of CLS-AX for the 
treatment of wet AMD, which we refer to as ODYSSEY. ODYSSEY will compare CLS-AX suprachoroidal injection and aflibercept intravitreal injection 
over 36 weeks and is expected to have 60 total participants with a 2:1 randomization. The primary outcome measure is a mean change in best corrected 
visual acuity from baseline to week 36. The secondary outcome measures are changes in visual function and ocular anatomy, need for supplemental 
treatment and treatment burden as measured by total injections over the trial duration. We began enrolling participants in May 2023 and randomized our 
first participants in July 2023. In October 2023 we completed the recruitment of participants. The final participant was randomized to the CLS-AX 
treatment of the aflibercept comparator arm in December 2023. We expect to report topline data in the third quarter of 2024.

Preclinical

We have an experienced team of scientists and researchers evaluating small molecules that may be utilized as potential treatment options for back of 

the eye diseases. This work often entails developing a suspension formulation for delivery into the suprachoroidal space via our SCS Microinjector. 
Suprachoroidal delivery of a new suspension could provide targeting, compartmentalization and durability advantages over topical or intravitreal delivery, 
similar to what we have observed with XIPERE and CLS-AX. Once a formulation is confirmed, we proceed with conducting non-human studies until 
enough data is collected to warrant submitting an IND for such a product candidate.

XIPERE (triamcinolone acetonide injectable suspension) for suprachoroidal use

Our first product, XIPERE, formerly known as CLS-TA, is a proprietary, preservative-free suspension of the corticosteroid triamcinolone acetonide, 

or TA, for suprachoroidal use. Corticosteroids are the standard of care in uveitis. They are effective at treating the inflammatory aspect of ocular disease, 
but when delivered locally, either topically as drops, intravitreally or by periocular injection, they have been associated with significant side effects, such as 
cataract formation or exacerbation and elevated IOP, which can lead to glaucoma. 

XIPERE was approved for the treatment of macular edema associated with uveitis. Uveitis is a set of ocular inflammatory conditions affecting 
approximately 350,000 patients in the United States and more than one million worldwide. Approximately one-third of uveitis patients develop uveitic 
macular edema, a build-up of fluid in the macula, the area of the retina responsible for sharp, straight-ahead vision. Macular edema is the leading cause of 
vision loss and blindness in uveitis patients and can occur from uveitis affecting any anatomic location—anterior, intermediate, posterior or panuveitis.

We are evaluating options for potential submissions to regulatory agencies in additional territories not currently licensed for the treatment of patients 

with macular edema associated with uveitis. 

External Collaborations Pipeline

In order to expand the global reach of our suprachoroidal injection platform, we have strategically partnered some of our assets for development 
and/or commercialization and intend to continue partnering our assets. By entering into these partnerships, we have been able to expand the use of our 
suprachoroidal injection platform to other indications and geographies globally. We currently have collaborations with Bausch + Lomb, Arctic Vision, 
REGENXBIO, Inc., Aura Biosciences, Inc. and BioCryst Pharmaceuticals, Inc. As discussed below in “—Royalty Purchase and Sale Agreement”, we are 
obligated to pay HealthCare Royalty Management, LLC, or HCR, any such royalties or milestone payments until we have satisfied our obligations under 
the Purchase and Sale Agreement. 

License agreement for commercialization of XIPERE in United States and Canada

On October 22, 2019, we entered into a License Agreement with Bausch + Lomb or, as amended, the Bausch License Agreement. Pursuant to the 
Bausch License Agreement, we granted an exclusive license to Bausch to develop, manufacture, distribute, promote, market and commercialize XIPERE 
using our SCS Microinjector, as well as specified other steroids, corticosteroids and NSAIDs in combination with the SCS Microinjector, or together with 
XIPERE, the Products, subject to specified exceptions, in the United States and Canada, or the Territory, for the treatment of ophthalmology indications, 
including non-infectious uveitis.  

Pursuant to the Bausch License Agreement, Bausch paid us an upfront payment of $5.0 million in October 2019. In October 2021, the FDA 

approved XIPERE, and we received $5.0 million from Bausch as a result of the approval. In January 2022, we received an additional payment of $10.0 
million related to the completion of pre-launch activities for XIPERE. In addition, Bausch agreed to pay up to an aggregate of $55.0 million in additional 
milestone payments upon the achievement of (i) specified regulatory approvals for specified additional indications of XIPERE and (ii) specified levels of 
annual net sales (as defined in the Bausch License Agreement). Further, during the applicable royalty term, we will also be entitled to receive tiered 
royalties at increasing percentages from the high-teens to twenty percent, based on XIPERE achieving certain annual net sales thresholds in the Territory, as 
well as a lower royalty on annual net sales of other products, in each case subject to reductions in specified circumstances. However, we will not receive 
any royalties on the first $45.0 million of cumulative net sales of all products in the Territory. Bausch launched XIPERE in the United States in the first 
quarter of 2022. Our rights to these royalties and milestone payments have been sold pursuant to the terms and conditions of the Purchase and Sale 
Agreement described below in "—Royalty Purchase and Sale Agreement."

The Bausch License Agreement will expire upon expiration of the royalty terms for all Products and countries in the Territory, with each royalty 

term for a given Product and country ending on the latest of (i) the date of expiration of the last-to-expire valid claim 

10

Table of Contents

of any licensed patent rights covering such Product in such country in the Territory, (ii) the date of the loss of regulatory exclusivity for such Product in 
such country in the Territory, or (iii) ten years from the later of the first sale of such Product in such country in the Territory. Bausch may also terminate the 
Bausch License Agreement for convenience upon 180 days’ written notice. In addition, we can terminate the Bausch License Agreement if Bausch 
commences a legal action challenging the validity, enforceability or scope of any of the licensed patents.  Both parties may terminate the Bausch License 
Agreement (i) upon a material breach of the Bausch License Agreement, subject to a specified cure period and specified exceptions, or (ii) if the other party 
encounters bankruptcy or insolvency.

License agreement for commercialization of XIPERE in China, Hong Kong, Macau, Taiwan and South Korea, India, ASEAN Countries, 

Australia and New Zealand

On March 10, 2020, we entered into a license agreement, or the Arctic Vision License Agreement, with Arctic Vision (Hong Kong) Limited, or 

Arctic Vision. Pursuant to the Arctic Vision License Agreement, we granted an exclusive license to Arctic Vision to develop, distribute, promote, market 
and commercialize XIPERE, subject to specified exceptions, in China, Hong Kong, Macau, Taiwan and South Korea, or the Arctic Territory. Under the 
terms of the Arctic Vision License Agreement, neither party may commercialize XIPERE in the other party’s territory. Arctic Vision has agreed to use 
commercially reasonably efforts to pursue development and commercialization of XIPERE for indications associated with uveitis in the Arctic Territory. In 
addition, with our consent, Arctic Vision will have the right, but not the obligation, to develop and commercialize XIPERE for additional indications in the 
Arctic Territory.

In March 2022, Arctic Vision announced dosing of the first patient in a Phase 1 clinical trial of ARVN011 in China for the treatment of diabetic 

macular edema. In July 2023, Arctic Vision announced the formal acceptance in Australia of its new drug application for suprachoroidal use of ARVN001 
for the treatment of uveitic macular edema. In October 2023, Arctic Vision completed enrollment in its Phase 3 randomized, double-blind, placebo-
controlled clinical trial in China for suprachoroidal use of ARVN001 for the treatment of uveitic macular edema. Arctic Vision has branded ARVN001 as 
Arcatus.

Pursuant to the Arctic Vision License Agreement, Arctic Vision paid us an upfront payment of $4.0 million in March 2020. In December 2021, we 
received a milestone payment of $4.0 million following receipt of FDA approval of XIPERE in the United States. In addition, Arctic Vision agreed to pay 
us up to a total of $22.5 million in development and sales milestone payments.  Further, during the applicable royalty term, we are also entitled to receive 
tiered royalties of 10% to 12% of net sales based on achieving certain annual net sales thresholds in the Arctic Territory, subject to customary reductions, 
payable on a product-by-product and country-by-country basis, commencing at launch in such country and lasting until the latest of (i) the date that all 
valid claims within the licensed patent rights covering XIPERE have expired, (ii) the date of the loss of marketing or regulatory exclusivity of XIPERE in a 
given country or (iii) ten years from the first commercial sale of XIPERE in a given country. Our rights to these royalties and milestone payments have 
been sold pursuant to the terms and conditions of the Purchase and Sale Agreement described below in "—Royalty Purchase and Sale Agreement."

The Arctic Vision License Agreement will expire upon the expiration of the last-to-expire royalty term.  Arctic Vision may terminate the Arctic 

Vision License Agreement for convenience upon 45 days’ notice if before regulatory approval in the Arctic Territory or 90 days’ notice if after regulatory 
approval in the Arctic Territory.  In addition, we can terminate the Arctic Vision License Agreement if Arctic Vision commences a legal action challenging 
the validity, enforceability or scope of the licensed patents.  Both parties may terminate the Arctic Vision License Agreement (i) upon a material breach of 
the Arctic Vision License Agreement, subject to a specified cure period, or (ii) if the other party enters bankruptcy.  Upon termination, all licenses and other 
rights granted to Arctic Vision pursuant to the Arctic Vision License Agreement would revert to us. If Arctic Vision exercises its termination right for 
convenience or if the Arctic Vision License Agreement terminates as a result of Arctic Vision’s material breach or bankruptcy, Arctic Vision will assign and 
transfer all regulatory approvals, related documents and trademarks (with respect to trademarks, only those specific to) pertaining to XIPERE in the Arctic 
Territory to us.  If Arctic Vision terminates the Arctic Vision License Agreement as a result of material breach by us or our bankruptcy after regulatory 
approval of XIPERE in the Arctic Territory, we are obligated to pay Arctic Vision royalties equal to a low-single digit percentage of net sales of XIPERE in 
the Arctic Territory. 

In August 2021, we entered into an amendment to the Arctic Vision License Agreement to expand the territories covered by the license to include 

India and the ASEAN Countries (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam).  In 
September 2021, we entered into a second amendment to the Arctic Vision License Agreement to expand the Arctic Territory to include Australia and New 
Zealand. We received an aggregate of $3.0 million in consideration for the expansion of the Arctic Territory.

Gene Therapy 

We believe our platform offers the potential for safer, targeted ocular gene therapy without some of the risks of surgery and subretinal 

administration. Suprachoroidal administration of gene therapy could ultimately enhance access to care because it does not require specialized gene therapy 
surgery treatment centers. The procedure for suprachoroidal injection is conducted in an office setting and is similar in terms of patient preparation and 
duration to the procedure for intravitreal injection.  Therefore, we believe our products could be incorporated into retina specialists’ standard medical 
practice.

During the past several years, gene therapy has demonstrated in preclinical studies and clinical trials conducted by third parties that genetic material 

can be effectively and tolerably introduced to the retinal tissues, most often using an adeno-associated virus, or AAV. Safe and reproducible delivery of 
gene therapy vector into the subretinal space is essential for successful targeting of the retinal pigment epithelium, or RPE, and photoreceptor rods or cones. 
Currently, the only approved retinal gene therapy and most investigational retinal gene therapies are delivered via retinal surgery at a limited number of 
specialized ocular gene therapy treatment centers. During the pars plana vitrectomy surgery, the surgeon creates a small hole in the retina to inject the gene 
therapy beneath the retina to the subretinal space without tearing or damaging the retina and macula. This process creates a small retinal detachment, which 
separates and exposes the photoreceptors and RPE to the gene therapy.  The retina is in a diseased state and already compromised and the procedure carries 
iatrogenic risk. However, the success of this surgery is critical for the clinical efficacy of retinal gene therapy. Consequently, the surgery requires extensive 
training and the limited number of specialized ocular gene therapy centers creates patient access issues. Unlike vitrectomy, suprachoroidal administration 
does not require detachment of the photoreceptors from the RPE, and consequently, avoids the risk of iatrogenic subretinal injection to an already-
compromised retina. Suprachoroidal injection procedure training is minimal and could ultimately enhance access to care because it would not have to be 
administered at a specialized gene therapy surgery treatment center.

Inherited retinal diseases, or IRDs, such as Stargardt disease and Usher syndrome, represent some of the most challenging diseases that 

ophthalmologists encounter. They cause progressive and relentless vision loss due to changes in genes critical to the survival of photoreceptors and RPE 
cells, yet delivery of therapeutics to these cells is challenging. In preclinical animal studies from which data was presented at the American Academy of 
Ophthalmology 2019 Annual Meeting in October 2019, the suprachoroidal injection of luciferase DNA nanoparticles, or DNPs, in rabbits produced activity 
comparable to that seen from subretinal injections of luciferase DNPs. In these studies, SCS injections of DNPs were generally well tolerated across both 
rabbits and non-human primates, and no significant abnormalities were observed on ophthalmic exams. DNPs can also transfer large genes at potentially 
higher doses without the risks of subretinal surgery, which may allow for gene therapy in some of the most common IRDs. 

We believe suprachoroidal administration may further enhance the value proposition of ocular gene therapy by potentially improving safety and 

expanding access. In preclinical studies we have observed that SCS injection can administer both viral and non-viral gene therapy. Using marker genes like 
green fluorescent protein and luciferase in both rabbits and non-human primates, gene therapy was delivered with our SCS injection to achieve expression 
in the retina and choroid. To expand our overall development pipeline, we are looking to selectively partner our proprietary technology for use with novel 
gene therapies.

REGENXBIO, Inc.

We have expanded the reach of our SCS Microinjector technology in AAV-based gene therapy through a development and commercial partner. 

In August 2019, we entered into an option and license agreement, or the REGENXBIO Option and License Agreement, with REGENXBIO Inc., or 

REGENXBIO, pursuant to which we granted REGENXBIO an exclusive option, or the Option, to enter into a commercial license agreement granting 
REGENXBIO an exclusive, worldwide and sublicensable license to our SCS Microinjector for the in-office delivery of AAV-based gene therapies for the 
treatment of wet AMD, diabetic retinopathy and other conditions for which anti-VEGF treatment is currently the standard of care. 

In October 2019, REGENXBIO exercised the Option and paid us an option fee equal to $2.0 million less $0.5 million received under a prior 
technology access agreement. Under the license agreement, REGENXBIO paid us $3.0 million in connection with a development milestone and agreed to 
additional payments to us of up to an aggregate of $31.0 million upon the achievement of specified development milestones and up to $102.0 million in 
sales-based milestone payments, as well as mid-single digit royalties on net sales of products using the SCS Microinjector during the royalty term. Our 
rights to these royalties and milestone payments have been sold pursuant to the terms and conditions of the Purchase and Sale Agreement described below 
in "—Royalty Purchase and Sale Agreement."

Table of Contents

REGENXBIO will be responsible for all development, regulatory and commercialization activities for their gene therapy product candidates. We 

will be responsible for supplying the SCS Microinjector in support of REGENXBIO’s preclinical studies, clinical studies and commercial use.

REGENXBIO is currently conducting two multi-center, open-label, randomized, controlled, dose-escalation Phase 2 clinical trials evaluating the 

efficacy, safety and tolerability of suprachoroidal delivery of ABBV-RGX-314 using our SCS Microinjector technology: (1) a Phase 2 trial entitled 
AAVIATE for the treatment of wet AMD; and (2) a second Phase 2 trial entitled ALTITUDE for the treatment of diabetic retinopathy, or DR. In November 
2023, REGENXBIO presented data from the ALTITUDE trial showing that, at one year, dose level 2 in non-proliferative DR patients prevented disease 
progression as measured by the Early Treatment Diabetic Retinopathy Study-Diabetic Retinopathy Severity Scale. In January 2024, REGENXBIO 
presented data from the AAVIATE trial demonstrating that, at six months, patients treated with ABBV-RGX-314 continue to demonstrate stable vision and 
retinal anatomy while a meaningful reduction in anti-VEGF treatment burden was observed. REGENXBIO expects to provide program updates for the 
ALTITUDE trial in the second quarter of this year and for the AAVIATE trial in mid-2024. 

Ocular Oncology

Ocular cancers are a group of rare, life-threatening conditions that affect one or both eyes. The main indications include choroidal melanoma, 
choroidal metastases, cancers of the ocular surface and retinoblastoma, among others. Diagnosing and treating these cancers early is important because they 
have the potential to spread both within the eye and to other organs. The risk for ocular cancer increases with age and increases significantly after the age of 
50. For cancers that occur inside the eye (e.g., choroidal melanoma), the typical treatment is radiotherapy in the form of plaque brachytherapy and proton 
beam therapy, but these treatments are highly invasive and result in major vision loss and other comorbidities for many patients. 

Choroidal melanoma is the most common intraocular cancer in adults, with an incidence of approximately 11,000 patients per year in the United 

States and Europe. This comprises approximately 90% of all cases of uveal melanoma, consisting of melanomas in the choroid, ciliary body and iris, which 
are collectively referred to as the uvea. It is estimated that 96% of patients are diagnosed early without clinical evidence of metastatic disease. There are 
approximately 2,000 new cases treated each year in the United States and 1,600 new cases treated each year in Europe. However, despite the current 
treatments with radiotherapy, the long-term prognosis is poor with death occurring in more than 50% of cases. There are no FDA-approved therapies for 
choroidal melanoma. There is a need for treatment of early-stage disease which includes small melanomas and indeterminate lesions representing 
approximately 9,000 patients in the United States and Europe. 

Aura Biosciences, Inc.

On July 9, 2019, we entered into a worldwide licensing agreement with Aura Biosciences, Inc., or Aura, for the use of our SCS Microinjector to 

deliver Aura’s proprietary drug candidates into the SCS for the potential treatment of certain ocular cancers, including choroidal melanoma. Our SCS 
Microinjector may offer a non-surgical alternative to intravitreal delivery of Aura’s oncology drug candidates, and we believe suprachoroidal 
administration may further enhance the value proposition of choroidal melanoma by potentially improving safety and expanding access. Pursuant to the 
licensing agreement, we have received an aggregate of  $1.6 million in connection with upfront license fees and development milestones. We are eligible to 
receive up to an additional $19.5 million in payments related to pre-specified development and regulatory milestones, as well as low to mid-single digit 
royalties on net sales that utilize the SCS Microinjector. Our rights to these royalties and milestone payments have been sold pursuant to the terms and 
conditions of the Purchase and Sale Agreement described below in "—Royalty Purchase and Sale Agreement."

Aura is utilizing our SCS Microinjector to deliver their viral like drug conjugate, bel-sar, for the treatment of choroidal melanoma. In November 
2023, Aura reported positive clinical safety and efficacy updates from its ongoing Phase 2 clinical trial with suprachoroidal administration. The results, 
with 90% of patients at twelve months of follow-up who received three cycles of therapy in Cohorts 5 and 6 and who match the criteria for the planned 
global Phase 3 trial, showed a tumor control rate of 80% and the visual acuity preservation rate was 90%. In December 2023, Aura announced the first 
patient dosed in CoMpass, their global Phase 3 clinical trial.

BioCryst Pharmaceuticals, Inc.

On November 1, 2023, we entered into a license agreement, or the BioCryst License Agreement, with BioCryst Pharmaceuticals, Inc., or BioCryst,  

pursuant to which we granted BioCryst an exclusive, worldwide and sublicensable license to our SCS Microinjector for the delivery of BioCryst’s 
proprietary plasma kallikrein inhibitor known as avoralstat for the treatment and prevention of diabetic macular edema, or DME. 

13

Table of Contents

We received an upfront license fee payment of $5.0 million in connection with signing of the BioCryst License Agreement. In addition, we are 
eligible to receive up to an additional $30.0 million in clinical and regulatory milestone payments, and up to a total of $47.5 million in a series of post-
approval sales-based milestone payments based on the achievement of annual global net product sales milestones up to $2.0 billion. Further, during the 
royalty term, BioCryst has also agreed to pay us tiered mid-single digit royalties on annual global net product sales, with the highest royalty rate applied to 
sales over $1.5 billion, subject to reductions in specified circumstances. Our rights to these royalties and milestone payments have been sold pursuant to the 
terms and conditions of the Purchase and Sale Agreement described below in "—Royalty Purchase and Sale Agreement."

BioCryst will be responsible for all development, regulatory and commercialization activities for avoralstat. We are responsible for supplying SCS 

Microinjectors to meet BioCryst’s reasonable needs.  

The BioCryst License Agreement, unless earlier terminated, will expire (a) on a country-by-country basis upon the expiration of the royalty term in 

such country or (b) in its entirety upon the expiration of all payment obligations of BioCryst under the BioCryst License Agreement in all countries 
pursuant to clause (a). Each party has the right terminate the BioCryst License Agreement (i) upon a material breach of the BioCryst License Agreement by 
the other party, subject to a specified cure period and specified exceptions, or (ii) if the other party encounters bankruptcy or insolvency. We may terminate 
the BioCryst License Agreement if BioCryst or any of its sublicensees, or a Sublicensee commences a legal action challenging the validity, enforceability 
or scope of any of the licensed patents, provided that with respect to any such action initiated by a Sublicensee, or Sublicensee Action, we may terminate 
the BioCryst License Agreement if the Sublicensee Action is not terminated within a specified period of time following BioCryst’s receipt of written notice 
from us or if BioCryst does not terminate the applicable sublicense, in each case within a specified period of time. BioCryst may terminate the BioCryst 
License Agreement (i) immediately upon written notice to us if, after exercising commercially reasonable efforts, BioCryst determines in good faith that it 
is not advisable to continue development or commercialization of avoralstat as a result of a material safety issue and (ii) in its entirety or in part on a 
country-by-country basis, for any or no reason, upon prior written notice to us, provided that in the event of such a termination, BioCryst shall not, for a 
period of two years from the date of such a termination, initiate in the territory subject to the termination a Phase 3 clinical trial in which avoralstat is 
administered to the suprachoroidal space using a device other than the SCS Microinjector.

Royalty Purchase and Sale Agreement

On August 8, 2022, or the Closing Date, we, through our wholly-owned subsidiary Clearside Royalty LLC, a Delaware limited liability company, or 

Royalty Sub, entered into a Purchase and Sale Agreement, or the Purchase and Sale Agreement, with entities managed by HealthCare Royalty 
Management, LLC, or HCR, pursuant to which Royalty Sub sold to HCR certain of its rights to receive royalty and milestone payments payable to Royalty 
Sub under the Arctic Vision License Agreement, the Bausch License Agreement, that certain License Agreement, effective as of July 3, 2019, by and 
between us and Aura Biosciences, Inc., or the Aura License Agreement, the REGENXBIO Option and License Agreement and any and all out-license 
agreements following the Closing Date for, or related to XIPERE  or the SCS Microinjector technology (to be used in connection with compounds or 
products of any third parties delivered, in whole or in part, by means of the SCS Microinjector technology), excluding, for the avoidance of doubt, any in-
licensed or internally developed therapies following the Closing Date, or the Royalties, in exchange for up to $65 million. In connection with this 
transaction, we assigned the Arctic Vision License Agreement, Bausch License Agreement, Aura License Agreement, REGENXBIO Option and License 
Agreement, our license agreement with Emory University and The Georgia Tech Research Corporation and related intellectual property rights to Royalty 
Sub.  

Under the terms of the Purchase and Sale Agreement, Royalty Sub received an initial payment of $32.1 million, representing the $32.5 million to 

which we were entitled, net of certain of HCR's transaction-related expenses which we agreed to reimburse. An additional $12.5 million was deposited by 
HCR in an escrow account which, was released to HCR pursuant to the Letter Agreement described below. The terms of the Purchase and Sale Agreement 
also provide for an additional $20 million milestone payment to Royalty Sub upon attainment of a second pre-specified sales milestone related to 2024 
XIPERE sales, or the Second Milestone Event. 

The Purchase and Sale Agreement will automatically expire, and the payment of Royalties from the Royalty Sub to HCR will cease, when HCR has 

received payments of the Royalties equal to 2.5 times the aggregate amount of payments made by HCR under the Agreement if the Second Milestone 
Event is achieved on or prior to December 31, 2024, or the Initial Cap. If the Second Milestone Event is not achieved on or prior to December 31, 2024, 
payment of Royalties from Royalty Sub to HCR will cease when HCR has received Royalties payments equal to 3.4 times the aggregate amount of 
payments under the Purchase and Sale Agreement, or the Alternative Cap.  In the event of a change in control, acquiror will have the option to make a 
payment to HCR of the Initial Cap or the Alternative Cap, depending on which is then in effect, less the aggregate amount of Royalty payments made by 
Royalty Sub to HCR under the Purchase and Sale Agreement as a one-time payment at which time, payment of Royalties to HCR will cease.  Alternatively, 
in the event of a change in control, the acquiror will have the option to make an initial payment of 1.0 times the aggregate amount of payments made by 
HCR under the Purchase and Sale Agreement as of the date of such change in control, then in that event, payment of Royalties from Royalty Sub to HCR 
will cease when HCR has received total Royalties payments (including the 

14

Table of Contents

initial payment) equal to the Alternative Cap. After the Purchase and Sale Agreement expires, all rights to receive the Royalties return to Royalty Sub.

On December 22, 2023, we, through Royalty Sub, entered into a letter agreement, or the Letter Agreement, with HCR and HCR Clearside SPV, LLC 

(as assignee of HCR Collateral Management, LLC), or Agent, amending the Purchase and Sale Agreement. Pursuant to the terms of the Letter Agreement, 
Royalty Sub and Agent mutually agreed that Royalty Sub waived any and all rights to the $12.5 million milestone payment which was deposited in an 
escrow account, or the First Milestone Payment, in connection with the closing of the transactions contemplated by the Purchase and Sale Agreement and 
agreed to the release of the First Milestone Payment to Agent. 

Manufacturing

We do not own any manufacturing facilities. We utilize contract manufacturing organizations, or CMOs, to formulate and produce our drug 

candidates and to produce our SCS Microinjector. We procure active pharmaceutical ingredients for our drugs from third-party suppliers. We expect to 
continue to utilize third-party manufacturers to produce quantities of our drug candidates and the SCS Microinjector.

On May 8, 2018, we entered into a supply agreement with Gerresheimer Regensburg GmbH to supply our SCS Microinjector. Unless terminated 

earlier pursuant to its terms, the Gerresheimer agreement has an initial term of five years, after which it renews in three-year increments unless either party 
gives notice of non-renewal at least one year in advance. Each party has the right to terminate the agreement for customary reasons such as material breach 
and bankruptcy. The Gerresheimer agreement contains provisions relating to compliance by Gerresheimer with current Good Manufacturing Practices, 
regulations promulgated by the FDA, confidentiality and other customary matters for an agreement of this nature. We may enter into commercial supply 
agreements with our other suppliers.

Commercialization 

We have entered into exclusive license agreements for the commercialization and development of XIPERE with Bausch + Lomb in the United 

States and Canada and with Arctic Vision in China, Hong Kong, Macau, Taiwan, South Korea, India, the ASEAN Countries, Australia and New Zealand. 
We may enter into distribution or licensing arrangements for commercialization rights for other regions. We have also entered into an exclusive license 
agreement for the use of our SCS Microinjector with BioCryst. If any of our future product candidates, including CLS-AX, are approved by the applicable 
regulatory authorities, we may either commercialize those product candidates ourselves or through license or collaboration agreements with third parties.

Competition

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on 
proprietary drugs. While we believe that our technologies, knowledge, experience and scientific resources provide us with competitive advantages, we face 
potential competition from many different sources, including major pharmaceutical companies, specialty pharmaceutical and biotechnology companies, 
government agencies and public, and private research and academic institutions. Any product candidate that we successfully develop and commercialize 
will compete with existing therapies and new therapies that may become available in the future. 

XIPERE faces competition from other commercially available forms of TA and other topical, injectable and implantable corticosteroids, although 

none are approved for the indication of macular edema associated with uveitis. Bristol-Myers Squibb markets TA, under the brand name Kenalog, for 
which a number of generic equivalents are currently available. Kenalog is indicated only for intramuscular or intraarticular injection; however, it is used 
off-label for intraocular inflammation using intravitreal and periocular administration. In addition, Alcon’s injectable TA, Triesence, is approved in the 
United States for the treatment of uveitis and other ocular inflammatory conditions unresponsive to topical corticosteroids, but it is not indicated for the 
treatment of macular edema associated with uveitis. Ozurdex, marketed by Allergan, is a bio-erodible, extended-release implant that delivers the 
corticosteroid and dexamethasone, and is approved for the treatment of non-infectious uveitis affecting the posterior segment of the eye and for macular 
edema due to retinal vein occlusion, or RVO, in both the United States and in the European Union. Ozurdex is also approved in the United States for the 
treatment of diabetic macular edema, or DME. Retisert and Yutiq, both intravitreal implants of fluocinolone acetonide, are marketed by Bausch and 
Alimera, respectively, and are approved in the United States for the treatment of chronic non-infectious uveitis affecting the posterior segment of the eye. In 
addition, Oxular is developing OXU-001 which is dexamethasone delivered via the Oxulumis suprachoroidal device for the treatment of DME.  It is 
possible physicians may use OXU-001 off label to treat macular edema associated with uveitis once approved.

Table of Contents

CLS-AX faces competition with anti-VEGF drugs, the current standard of care for RVO and wet AMD, as well as other drug candidates in 

development for ocular use for the treatment of wet AMD, such as other TKI’s. Axitinib, also known by its brand name Inlyta, is not currently approved for 
an ocular indication but is approved by the FDA and marketed by Pfizer for the treatment of advanced renal cell carcinoma. Genentech has several products 
which serve as competitors in this space, including anti-VEGF agents Lucentis, Avastin, and Susvimo. Lucentis is currently approved in the United States 
and European Union for the treatment of wet AMD, macular edema following RVO, and diabetic retinopathy in patients with DME. Avastin is an anti-
VEGF drug routinely used off-label by uveitis and retina specialists in both the United States and in certain countries of the European Union for the 
treatment of numerous retinal diseases. Susvimo, an ocular implant that releases ranibizumab over time, received approval from the FDA in October 2021 
for the treatment of wet AMD in patients who have previously responded to anti-VEGF therapy. Additionally, Genentech’s product, Vabysmo (faricimab-
svoa), an intravitreal injection which blocks two disease pathways, including (Ang-2) and vascular endothelial growth factor-A (VEGF-A), received 
approval in January 2022 for the treatment of wet AMD and diabetic macular edema. 

In addition to Genentech’s products, Regeneron’s anti-VEGF product, Eylea 2 mg and 8 mg and Novartis’ product, Beovu, also present potential 

competition for CLS-AX in both the United States and Europe. Eylea is approved for the treatment of wet AMD, macular edema following RVO and 
diabetic retinopathy and DME in the United States and for the treatment of wet AMD, RVO and DME in the European Union. 

Additional future competition may emerge from biosimilar anti-VEGF products as they are approved and enter the market.

Ocular drug candidates being investigated for treatment of wet AMD may also represent potential competition for CLS-AX. Ocular Therapeutics 

and Eyepoint are companies currently investigating TKIs for ocular use in late-stage clinical trials. We expect other established companies will seek to 
develop new products in the ocular space with the goal of superior efficacy and duration over the current standard of care. 

REGENXBIO, Adverum, and 4D Molecular Therapeutics are currently conducting mid to late-stage clinical trials with various ocular gene therapies 

for the treatment of wet AMD. These gene-based treatments could potentially compete with CLS-AX due to their potential to be long-acting treatments.  

The SCS Microinjector faces competition from other devices being developed to access ocular posterior tissues via the SCS. Oxular Limited and 

Everads both have developed competing products and are in various stages of early-stage clinical development. 

Both large and established companies, as well as smaller or early-stage companies could represent challenges in the competitive space.  Larger 

established companies may have greater resources such as greater financial resources, deeper expertise and personnel in nonclinical development, clinical 
development, manufacturing and regulatory sectors.  Smaller or early-stage companies could pose a challenge competitively through collaborative 
arrangements with large and established companies.  Lastly, both small and large companies will compete in areas such as recruiting and retaining qualified 
scientific and management personnel and establishing clinical trial sites and patient recruitment for competing clinical trials.

Several key competitive factors affecting the potential success of our product candidates are likely to be the efficacy, safety, method of 

administration, convenience, price and the availability of coverage and reimbursement from government and other third-party payors.  Additionally, our 
commercial opportunity could be reduced or eliminated if our competitors develop and commercialize drugs that are safer, more effective, more convenient 
or are less expensive than any drugs we develop.  The timing of competitors’ regulatory approval and patent protection could also impact commercial 
opportunities.  Competitors receiving approval prior to us could result in stronger market positioning and/or obtaining FDA market exclusivity. 
Competitors’ patent protection could potentially delay FDA approval of our product candidates for up to 30 months, as well as subject us to potential patent 
litigation that might arise beyond the 30 months.

Intellectual property

Our success depends in part on our ability to obtain and maintain patent and other intellectual property and proprietary protection for our 

technologies and methods of accessing the SCS, drug candidates and formulations as well as patent and other intellectual property and proprietary 
protection for novel applications, uses and technological innovations related to our drug candidates, proprietary delivery devices and core technologies. We 
also rely on trade secrets, know-how and continuing technological innovation to develop and maintain our proprietary position.

Patents and patent applications 

Our patent estate, on a worldwide basis, includes 28 granted U.S. patents broadly directed to devices and methods of administering drugs into the 

SCS by injection, including one design patent. In addition, our patent estate includes 21 patent applications pending in the United States, 88 issued foreign 
patents, 2 pending international PCT applications and 39 patent applications pending in major international markets, including the European Union, 
Canada, India, Japan, China and Australia, relating to our SCS delivery technology, as well as the formulations of our current therapeutic drug candidates 
and delivery device. Of these patents and patent applications, we license 8 issued U.S. patents, 4 pending U.S. applications, and 23 of the issued foreign 
patents in major international markets, each relating to devices or methods of delivering drugs to the eye by microneedle administration, pursuant to a 
license agreement with Georgia Tech Research Corporation and Emory University that is described below. With respect to in-licensed international PCT 
applications, according to the terms of the license agreement, we advise Georgia Tech and Emory regarding the countries in which patent applications 
should be pursued. Subject to payment of required maintenance fees, annuities and other charges, our issued in-licensed U.S. patents are expected to expire 
between 2027 and 2029, without taking into account possible patent term adjustments or extensions. Applications relating to SCS delivery technology and 
methods, our current therapeutic drug candidates and formulations, various therapeutic uses, including treatment of specific indications such as macular 
edema associated with uveitis and RVO, wet AMD as well as DME and improvement of specified clinical parameters, are expected to expire, if issued, 
between 2027 and 2042, without taking into account possible patent term adjustments or extensions. 

The term of individual patents depends on the legal term for patents in the countries in which they are granted. In most countries, including the 
United States, the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In 
the United States, a patent’s term may, in certain cases, be extended by patent term adjustment, which compensates a patentee for administrative delays by 
the U.S. Patent and Trademark Office in examining and granting a patent, or may be shortened if a patent is terminally disclaimed over a commonly owned 
patent or a patent naming a common inventor and having an earlier expiration date. The Drug Price Competition and Patent Term Restoration Act of 1984, 
or the Hatch-Waxman Act, permits a patent term extension of up to five years beyond the expiration date of a U.S. patent as partial compensation for the 
length of time the drug is under regulatory review. 

Our product candidates are protected against genericization through numerous patents. In the case of XIPERE injected into the SCS, an applicant 

who files a paragraph 4 Abbreviated New Drug Application, or ANDA, or 505(b)(2) NDA certifying they may circumvent our patents must also 
demonstrate comparability of the proposed drug, which we believe may require a clinical trial in macular edema associated with uveitis, against our 
product, unless a biowaiver is obtained. 

Third-party patent filings 

Numerous U.S. and foreign issued patents and patent applications owned by third parties exist in the fields in which we are developing products, 
including patents and applications related to surgical methods of accessing the SCS and certain formulations of TA. Because patent applications can take 
many years to issue, there may be applications unknown to us, which may later result in issued patents that our product candidates or proprietary 
technologies may infringe. 

Under U.S. law, a person may be able to patent a discovery of a new way to use a previously known compound, even if such compound itself is 

patented, provided the newly discovered use is novel and nonobvious. Such a method-of-use patent, however, if valid, only protects the use of a claimed 
compound for the specified methods claimed in the patent. This type of patent does not prevent persons from using the compound for any previously 
known use of the compound. Further, this type of patent does not prevent persons from making and marketing the compound for an indication that is 
outside the scope of the patented method. 

License agreement with Emory and Georgia Tech 

We have entered into a license agreement, or the Georgia Tech License Agreement, with Emory University, or Emory, and the Georgia Tech 

Research Corporation, or GTRC and together with Emory, the Licensor, under which we received a worldwide exclusive license to specified patents 
relating to methods and devices for drug delivery using a microinjector. The field of the license covers all ophthalmic uses of the microinjector for 
mammals and birds. Under this license agreement, we have agreed to direct all prosecution of intellectual property to the licensors’ patent counsel and have 
agreed to pay for all intellectual property expenses associated with the licensed patents. 

In addition to upfront and milestone payments of $65,000 in the aggregate made to date, we made a $75,000 payment related to a milestone that was 

achieved in December 2021 for the commercialization of a drug developed using the licensed patents. On July 1, 2018 and 2019, we paid Emory and 
GTRC $75,000 and $50,000, respectively, to extend the date by which we may achieve the commercialization milestone. Additionally, we are currently 
paying a low single-digit royalty on any worldwide net product sales related to the licensed patents, with minimum annual royalties starting at $15,000 per 
year after commercialization. The minimum 

17

Table of Contents

annual royalty increases each year after the first commercial sale, up to a maximum amount of $100,000 per year in the sixth calendar year and in 
subsequent years. 

On January 31, 2024, or the Amendment Execution Date, we and the Licensor entered into an amendment, or the Amendment, to the Georgia Tech 

License Agreement.

Pursuant to the Amendment, the parties agreed to reduce the Sublicense Percentage (as defined in the Georgia Tech License Agreement) from a low 
double digit percentage to a high single digit percentage that we will pay the Licensor applicable to any fees or payments paid to us by any Sublicensee (as 
defined in the Georgia Tech License Agreement) of the Licensed Patents and/or Licensed Technology (each as defined in the Georgia Tech License 
Agreement), on or after July 1, 2023, excluding (i) amounts paid to us by a Sublicensee to reimburse us for certain research and development costs 
pursuant to a written agreement between us and such Sublicensee, (ii) the value of intellectual property transferred or granted to us if necessary or helpful 
to the development or commercialization of Licensed Products (as defined in the License Agreement) and (iii) amounts paid for shares of our stock. The 
payment to Licensor of any such Sublicense Percentage is due within 30 days of receipt by us of a qualifying payment from a Sublicensee, provided 
however, with respect to any qualifying payments received by us from a Sublicensee after July 1, 2023 but prior to January 1, 2025, the payment to 
Licensor of any such Sublicensee Percentage is due to Licensor by March 31, 2025.

In addition, the parties agreed to a revised annual license maintenance fee due each year, or the Maintenance Fee, starting in 2023 through 2028, as 

follows: $250,000 for 2023 through 2025, $350,000 for 2026, $400,000 for 2027 and $500,000 for 2028. We paid the Maintenance Fee for 2023 in 
February 2024. The remaining annual Maintenance Fee payments are due on October 1st of each year.

The remaining terms of the Georgia Tech License Agreement, including the low single digit royalty rate paid to the Licensor by us on sales of 

Licensed Products, were unchanged by the Amendment.

We are solely responsible for the development and commercialization of products related to the licensed patients. We are obligated to provide Emory

and GTRC a written report detailing our activities related to the development and commercialization of products twice a year. 

Royalties are calculated based on net sales of products covered by a patent licensed under the agreement and are due on each such product sold as 
long as the patent covering that particular product is valid and unexpired. Unless otherwise terminated pursuant to its termination provisions, the Georgia 
Tech License Agreement will expire upon the expiration of the last to expire of the licensed patents. We have the right to terminate the Georgia Tech 
License Agreement at any time upon 60 days’ written notice to Emory and GTRC. Emory and GTRC may also terminate the Georgia Tech License 
Agreement in the event of a material breach by us. The Georgia Tech License Agreement will immediately terminate if we challenge the validity or 
enforceability of any of the licensed patents in a court or other governmental agency of competent jurisdiction. 

Trademarks, trade secrets and know-how 

Our trademark portfolio currently consists of two registered trademarks in Australia and Korea, two registered trademarks in Russia, two registered 

trademarks in Singapore, six registered trademarks in Brazil, five registered and one pending application in Canada, five registered trademarks, one 
pending and one unfiled trademarks in China, six registered trademarks in the European Union, two registered trademarks in each of India and New 
Zealand, one registered trademarks in Japan, three registered, one pending and two unfiled applications in Israel, eight registered trademarks and one 
pending in Mexico, four registered and three pending applications in South Africa, six registered trademarks and four pending applications in the United 
States and six registered trademarks in the United Kingdom. We also have three international registrations: the first with registered protection in the 
European Union, India, Japan, New Zealand, Korea and Singapore; the second with registered protection in Australia, China, European Union, India, 
Israel, Japan, Korea, Mexico, New Zealand, Russia, and Singapore; and the third with extensions of protection pending in Australia, Brazil, Canada, Japan 
and Mexico.

Government regulation

In the United States, the FDA regulates drug and device products under the Food, Drug and Cosmetic Act, or FDCA, and its implementing 

regulations. This includes combination products where a drug and a device are used together.

In the case of our product candidates, the primary mode of action is attributable to the drug component of the product, which means that the FDA’s 

Center for Drug Evaluation and Research, has primary jurisdiction over the premarket development, review and approval of our product candidates. 

18

Table of Contents

Drugs 

The clinical testing, manufacturing, labeling, storage, distribution, record keeping, advertising, promotion, import, export and marketing, among 

other things, of our product candidates are governed by extensive regulation by governmental authorities in the United States and other countries. The 
FDA, under the FDCA, regulates pharmaceutical products in the United States. The steps required before a drug may be approved for marketing in the 
United States generally include: 

•

•

•

•

•

•

preclinical laboratory tests and animal tests conducted under good laboratory practice;

the submission to the FDA of an IND application for human clinical testing, which must become effective before human clinical trials 
commence;

adequate and well-controlled human clinical trials to establish the safety and efficacy of the product and conducted in accordance with Good 
Clinical Practices, or GCP;

the submission to the FDA of an NDA;

FDA acceptance, review and approval of the NDA, which might include an Advisory Committee review; and

satisfactory completion of an FDA inspection of the manufacturing facilities at which the product is made to assess compliance with current 
Good Manufacturing Practices, or cGMPs.

The testing and approval process requires substantial time, effort and financial resources, and the receipt and timing of any approval is uncertain. 

The FDA may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable 
health risk. 

Preclinical studies include laboratory evaluations of the product candidate, as well as animal studies to assess the potential safety and efficacy of the 

product candidate. The results of the preclinical studies, together with manufacturing information and analytical data, are submitted to the FDA as part of 
the IND, which must become effective before clinical trials may be commenced. The IND will become effective automatically 30 days after receipt by the 
FDA, unless the FDA raises concerns or questions about the conduct of the trials as outlined in the IND prior to that time. In this case, the IND sponsor and 
the FDA must resolve any outstanding concerns before clinical trials can proceed. The FDA or an independent institutional review board, or IRB, may 
nevertheless initiate a clinical hold after the 30 days if, for example, significant health risks arise. 

In the United States, each clinical trial must be reviewed and approved by an IRB at each of the sites at which the trial will be conducted. The IRB 

will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. 

Clinical trials are typically conducted in three sequential phases prior to approval, but the phases may overlap. These phases generally include the 

following: 

Phase 1. Phase 1 clinical trials represent the initial introduction of a product candidate into human subjects, frequently healthy volunteers. In Phase 

1, the product candidate is usually tested for safety, including adverse effects, dosage tolerance, absorption, distribution, metabolism, excretion and 
pharmacodynamics. 

Phase 2. Phase 2 clinical trials usually involve studies in a limited patient population to (1) evaluate the efficacy of the product candidate for 

specific indications, (2) determine dosage tolerance and optimal dosage and (3) identify possible adverse effects and safety risks. 

Phase 3. If a product candidate is found to be potentially effective and to have an acceptable safety profile in Phase 2 clinical trials, the clinical trial 

program will be expanded to Phase 3 clinical trials to further demonstrate clinical efficacy, optimal dosage and safety within an expanded patient 
population at geographically dispersed clinical trial sites. 

Phase 4 clinical trials may be conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic 

indication and to document a clinical benefit in the case of drugs approved under accelerated approval regulations, or when otherwise requested by the 
FDA in the form of post-market requirements or commitments. Failure to promptly conduct any required Phase 4 clinical trials could result in enforcement 
action or withdrawal of approval. 

The results of preclinical studies and clinical trials, together with detailed information on the manufacture, composition and quality of the product, 

are submitted to the FDA in the form of an NDA, requesting approval to market the product. The application must be accompanied by a significant user fee 
payment, although waivers may be granted and exemptions apply in limited cases. The 

19

Table of Contents

FDA has substantial discretion in the approval process and may refuse to accept any application or decide that the data is insufficient for approval and 
require additional preclinical, clinical or other studies. 

Review of application 

Once an NDA has been accepted for filing, which occurs, if at all, 60 days after submission, the FDA sets a user fee goal date that informs the 

applicant of the specific date by which the FDA intends to complete its review. This is typically 10 months from the date of submission for drugs that are 
not new molecular entities, such as our product candidates. The review process can be expedited if priority review is granted.  In such a case, the FDA 
review period is only 6 months.  Alternatively, the FDA review process can be extended by FDA requests for additional information or clarification. The 
FDA reviews NDAs 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 cGMPs to assure and preserve the product’s identity, strength, quality and purity. Before approving an NDA, the 
FDA may inspect the facilities at which the product is manufactured and will not approve the product unless the manufacturing facility complies with 
cGMPs and may also inspect clinical trial sites for integrity of the data supporting safety and efficacy. The device component of our products will also be 
subject to review as part of the NDA review process and its manufacturers subject to inspection for compliance with device cGMPs embodied in the 
Quality System Regulation, or QSR. During the approval process, the FDA also will determine whether a risk evaluation and mitigation strategy, or REMS, 
is necessary to assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor of the application must submit a proposed REMS, 
and the FDA will not approve the application without an approved REMS, if required. A REMS can substantially increase the costs of obtaining approval. 
The FDA could also require a special warning, known as a boxed warning, to be included in the product label in order to highlight a particular safety risk. 
The FDA may also convene an advisory committee of external experts to provide input on certain review issues relating to risk, benefit and interpretation 
of clinical trial data. The FDA may delay approval of an NDA if applicable regulatory criteria are not satisfied and/or the FDA requires additional testing or 
information. The FDA may require post-marketing testing and surveillance to monitor safety or efficacy of a product. The FDA will issue either an 
approval of the NDA or a complete response letter, or CRL, detailing the deficiencies and information required for reconsideration of the application. 

Post-approval requirements 

Approved drugs that are manufactured or distributed in the United States are subject to pervasive and continuing regulation by the FDA, including, 

among other things, requirements relating to recordkeeping, periodic reporting, product distribution, advertising and promotion and reporting of adverse 
experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims and some 
manufacturing and supplier changes are subject to prior FDA review and approval. There also are continuing, annual program user fee requirements for 
approved products, as well as new application fees for certain supplemental applications. 

The FDA may impose a number of post-approval requirements as a condition of approval of an NDA. For example, the FDA may require post-

marketing testing, including Phase 4 clinical trials, and surveillance to further assess and monitor the product’s safety and effectiveness after 
commercialization. The FDA may also require a REMS, which could involve requirements for, among other things, a medication guide, special training for 
prescribers and dispensers, and patient registries. 

In addition, entities involved in the manufacture and distribution of approved devices or drugs are required to register their establishments with the 

FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP 
requirements. The FDA has promulgated specific requirements for drug cGMPs, device cGMPs embodied in the QSR and combination product cGMPs 
that, for drug/device combination products, specify the requirements within the drug cGMPs and the QSR with which manufacturers must comply. Changes 
to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require 
investigation and correction of any deviations from cGMP requirements and impose reporting and documentation requirements upon the sponsor and any 
third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of 
production and quality control to maintain cGMP compliance. 

Once an approval is granted, the FDA may issue enforcement letters or withdraw the approval if compliance with regulatory requirements and 

standards is not maintained or if problems occur after the product reaches the market. Corrective action could delay product distribution and require 
significant time and financial expenditures. Later discovery of previously unknown problems with a product, including adverse events of unanticipated 
severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling 
to add new safety information; imposition of post-market 

20

Table of Contents

studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences 
include, among other things: 

•

•

•

•

•

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

fines, warning letters or holds on post-approval clinical trials;

refusal of the FDA to approve applications or supplements to approved applications, or suspension or revocation of product approvals;

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

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only 

for the approved indications and in accordance with the provisions of the approved label. Physicians, on the other hand, may prescribe products for off-
label uses. Although the FDA and other regulatory agencies do not regulate a physician’s choice of drug treatment made in the physician’s independent 
medical judgment, they do restrict promotional communications from companies or their sales force with respect to off-label uses of products for which 
marketing clearance has not been issued. However, companies may share truthful and not misleading information that is otherwise consistent with the 
product’s FDA approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, 
including without limitation the FDCA, the federal civil False Claims Act, other federal and state health care fraud and abuse laws and state consumer 
protection laws. A company that is found to have improperly promoted off-label uses may be subject to significant liability, including investigation by 
federal and state authorities. 

The Hatch-Waxman amendments 

One of our regulatory strategies is to pursue development of our drugs as Section 505(b)(2) NDAs under the FDCA. As an alternative path to FDA 
approval for modifications to formulations or uses of drugs previously approved by the FDA, an applicant may submit an NDA under Section 505(b)(2) of 
the FDCA. Section 505(b)(2) was enacted as part of the Hatch-Waxman Amendments. A Section 505(b)(2) NDA is an application that contains full reports 
of investigations of safety and effectiveness, but where at least some of the information required for approval comes from studies not conducted by, or for, 
the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted. 
This type of application permits reliance for such approvals on literature or on an FDA finding of safety, effectiveness or both for an approved drug 
product. As such, under Section 505(b)(2), the FDA may rely, for approval of an NDA, on data not developed by the applicant. Therefore, if we can satisfy 
the conditions required for a Section 505(b)(2) NDA submission, it may eliminate the need for us to conduct some of the preclinical studies or clinical trials 
for the new product candidate that might otherwise have been required, although the review time is not shortened. As a condition for approval, the FDA 
may also require us to perform additional studies or measurements, including clinical trials, to support the change from the approved branded reference 
drug. 

Orange Book listing  

In seeking approval for a drug through an NDA, including a 505(b)(2) NDA, applicants are required to list with the FDA certain patents whose 
claims cover the applicant’s product. Upon approval of an NDA, each of the patents listed in the application for the drug is then published in the FDA’s 
Approved Drug Products with Therapeutic Equivalence Evaluations, known as the Orange Book. Any applicant who files an Abbreviated New Drug 
Application, or ANDA, seeking approval of a generic equivalent version of a drug listed in the Orange Book or a 505(b)(2) NDA referencing a drug listed 
in the Orange Book must certify, for each patent listed in the Orange Book for the referenced drug, to the FDA that (1) no patent information on the drug 
product that is the subject of the application has been submitted to the FDA, (2) such patent has expired, (3) the date on which such patent expires or (4) 
such patent is invalid or will not be infringed upon by the manufacture, use or sale of the drug product for which the application is submitted. The fourth 
certification described above is known as a paragraph IV certification. A notice of the paragraph IV certification must be provided to each owner of the 
patent that is the subject of the certification and to the holder of the approved NDA to which the ANDA or 505(b)(2) application refers. The applicant may 
also elect to submit a “section viii” statement certifying that its proposed label does not contain (or carves out) any language regarding the patented 
method-of-use rather than certify to a listed method-of-use patent. This section viii statement does not require notice to the patent holder or NDA owner. 
There might also be no relevant patent certification. 

If the reference NDA holder and patent owners file patent litigation directed to one of the Orange Book listed patents within 45 days of the receipt of 

the paragraph IV certification notice, the FDA is prohibited from approving the application until the earlier of 30 months from the receipt of the paragraph 
IV certification, expiration of the patent, settlement of the lawsuit or a decision in the case 

21

Table of Contents

that is favorable to the applicant. Even if the 45 days expire, a patent infringement lawsuit can be brought and could delay market entry, but it would not 
extend the FDA-related 30-month stay of approval. 

The ANDA or 505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the branded 

reference drug has expired as described in further detail below. 

Non-patent exclusivity 

In addition to patent exclusivity, the holder of the NDA for the listed drug may be entitled to a period of non-patent exclusivity, during which the 

FDA cannot approve an ANDA or 505(b)(2) application that relies on the listed drug. 

A drug, including one approved under a 505(b)(2) application, may obtain a three-year period of non-patent market exclusivity for a particular 

condition of approval, or change to a marketed product, such as a new formulation for a previously approved product, if one or more new clinical studies 
(other than bioavailability or bioequivalence studies) was essential to the approval of the application and was conducted/sponsored by the applicant. Should 
this occur, the FDA would be precluded from approving any ANDA or 505(b)(2) application until after that three-year exclusivity period has run. However, 
the FDA can accept an application and begin the review process during the three-year exclusivity period. A 505(b)(2) NDA may also be subject to a five-
year exclusivity period for a new chemical entity, whereby the FDA will not accept for filing, with limited exception, a product seeking to rely upon the 
FDA’s findings of safety or effectiveness for such new chemical entity. 

Orphan drugs 

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug intended to treat a rare disease or condition affecting fewer than 
200,000 individuals in the United States, or in other limited cases. Orphan drug designation does not convey any advantage in or shorten the duration of the 
regulatory review and approval process, though companies developing orphan drugs are eligible for certain incentives, including tax credits for qualified 
clinical testing. In addition, an NDA for a product that has received orphan drug designation is not subject to a prescription drug user fee unless the 
application includes an indication other than the rare disease or condition for which the drug was designated. 

If a product that has orphan drug designation subsequently receives the first FDA approval for the disease or condition for which it has such 
designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same active 
moiety for the same indication for seven years, except in limited circumstances, such as another drug’s showing of clinical superiority over the drug with 
orphan exclusivity. Competitors, however, may receive approval of different active moieties for the same indication or obtain approval for the same active 
moiety for a different indication. In addition, doctors may prescribe products for off-label uses and undermine our exclusivity. Orphan drug exclusivity 
could block the approval of one of our products for seven years if a competitor obtains approval for the same active moiety for the same indication before 
we do, unless we are able to demonstrate that our product is clinically superior. 

We may seek orphan drug designation for products in the future. We cannot guarantee that we will obtain orphan drug designation for any products 
in any jurisdiction. Even if we are able to obtain orphan drug designation for a product, we cannot be sure that such product will be approved, that we will 
be able to obtain orphan drug exclusivity upon approval, if ever, or that we will be able to maintain any exclusivity that is granted. 

Foreign regulation 

In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other 

countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial 
sales and distribution of our products. Whether or not we obtain FDA approval for a product, we would need to obtain the necessary approvals by the 
comparable foreign regulatory authorities before we can commence clinical trials or marketing of the product in foreign countries and jurisdictions. 
Although many of the issues discussed above with respect to the United States apply similarly in the context of the European Union and other geographies, 
the approval process varies between countries and jurisdictions and can involve additional product testing and additional administrative review periods. The 
time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory 
approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country 
or jurisdiction may negatively impact the regulatory process in others. 

Federal and state fraud and abuse, data privacy and security and transparency laws 

22

Table of Contents

In addition to FDA restrictions on marketing and promotion of drugs and devices, other federal and state laws restrict our business practices. These 

laws include, without limitation, anti-kickback and false claims laws, data privacy and security laws, as well as transparency laws regarding payments or 
other items of value provided to healthcare providers. 

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting or receiving any remuneration 
(including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, to induce or in return for purchasing, leasing, ordering or arranging for 
or recommending the purchase, lease or order of any good, facility, item or service reimbursable, in whole or in part, under Medicare, Medicaid or other 
federal healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value. Although there are a number of statutory 
exceptions and regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices 
that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny if they do not 
qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor does 
not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality of the arrangement will be evaluated on a case-by-case 
basis based on a cumulative review of all its facts and circumstances. Several courts have interpreted the statute’s intent requirement to mean that if any one 
purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the federal Anti-Kickback Statute has been 
violated. Therefore, even if we structure our programs with the intent of compliance with such laws, there can be no certainty that we would not need to 
defend ourselves against enforcement or litigation due to the fact that there is significant enforcement interest in life sciences companies in the United 
States and some of the applicable laws are broad in scope.

Additionally, the intent standard under the federal Anti-Kickback Statute was amended by the Patient Protection and Affordable Care Act, as 

amended by the Health Care and Education Reconciliation Act of 2010, collectively the Affordable Care Act, to a stricter standard such that a person or 
entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the 
Affordable Care Act codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a 
false or fraudulent claim for purposes of the federal civil False Claims Act. 

The federal civil False Claims Act prohibits, among other things, any person or entity from knowingly presenting, or causing to be presented, a false 

or fraudulent claim for payment or approval to the federal government or knowingly making, using or causing to be made or used a false record or 
statement material to a false or fraudulent claim to the federal government. A claim includes “any request or demand” for money or property presented to 
the U.S. government. The federal civil False Claims Act also applies to false submissions that cause the government to be paid less than the amount to 
which it is entitled, such as a rebate. Intent to deceive is not required to establish liability under the federal civil False Claims Act. Pharmaceutical, device 
and other healthcare companies have been prosecuted under these laws for, among other things, allegedly providing free product to customers with the 
expectation that the customers would bill federal programs for the product. Companies have been prosecuted for causing false claims to be submitted 
because of the companies’ marketing of products for unapproved, and thus non-covered, uses. 

The government may further prosecute conduct constituting a false claim under the federal criminal False Claims Act. The federal criminal False 

Claims Act prohibits the making or presenting of a claim to the government knowing such claim to be false, fictitious, or fraudulent and, unlike the federal 
civil False Claims Act, requires proof of intent to submit a false claim. 

The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal and civil statutes that 
prohibit, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including 
private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation 
of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or 
fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Like the federal Anti-Kickback Statute, the 
Affordable Care Act amended the intent standard for certain healthcare fraud statutes under HIPAA such that a person or entity no longer needs to have 
actual knowledge of the statute or specific intent to violate it in order to have committed a violation. 

The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is determined to have presented or 
caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed 
or is false or fraudulent. 

Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to 

items and services reimbursed under Medicaid and other state programs. 

Under HIPAA, the U.S. Department of Health and Human Services, or HHS, has issued regulations to protect the privacy and security of protected 

health information used or disclosed by covered entities including certain health care providers, health plans, and 

23

Table of Contents

healthcare clearinghouses. HIPAA also regulates standardization of data content, codes and formats used in health care transactions and standardization of 
identifiers for health plans and providers. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or 
HITECH and their regulations, including the omnibus final rule published on January 25, 2013, also imposes certain obligations on the business associates 
of covered entities that obtain protected health information in providing services to or on behalf of covered entities and their subcontractors that use, 
disclose, access, or otherwise process protected health information. In addition to federal privacy regulations, there are a number of state laws governing 
confidentiality and security of health information that are applicable to our business. In addition to possible federal civil and criminal penalties for HIPAA 
violations, state attorneys general are authorized to file civil actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees 
and costs associated with pursuing federal civil actions.  Accordingly, state attorneys general (along with private plaintiffs) have brought civil actions 
seeking injunctions and damages resulting from alleged violations of HIPAA’s privacy and security rules.  New laws and regulations governing privacy and 
security may be adopted in the future as well. 

Outside the United States, an increasing number of laws, regulations, and industry standards govern data privacy and security.  For example, the 
European Union’s General Data Protection Regulation, or EU GDPR, and the United Kingdom’s GDPR, or UK GDPR, impose strict requirements for 
processing personal data.  Under the EU GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of 
up to 20 million Euros or 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes 
of data subjects or consumer protection organizations authorized at law to represent their interests. In Canada, the Personal Information Protection and 
Electronic Documents Act and various related provincial laws, as well as Canada’s Anti-Spam Legislation, may, in the future, apply to our operations. 

In the ordinary course of business, we may transfer personal data from Europe and other jurisdictions to the United States or other countries.  Europe 

and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In particular, the 
European Economic Area (EEA) and the United Kingdom (UK) have significantly restricted the transfer of personal data to the United States and other 
countries whose privacy laws it believes are inadequate.  Although there are currently various mechanisms that may be used to transfer personal data from 
the EEA and UK to the United States in compliance with law, such as the EEA and UK’s standard contractual clauses, these mechanisms are subject to 
legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States.  If there is no 
lawful manner for us to transfer personal data from the EEA, the UK or other jurisdictions to the United States, or if the requirements for a legally-
compliant transfer are too onerous, we could face significant adverse consequences, including increased exposure to regulatory actions, substantial fines 
and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of 
personal data necessary to operate our business.   Additionally, companies that transfer personal data out of the EEA and UK to other jurisdictions, 
particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups.

Additionally, California has enacted legislation that has been dubbed the first “GDPR-like” law in the United States.  Known as the California 
Consumer Privacy Act, or CCPA, it applies to personal information of consumers, business representatives, and employees, and requires businesses to 
provide specific disclosures in privacy notices and honor requests of California residents to exercise certain privacy rights.  The CCPA provides for civil 
penalties of up to $7,500 per violation and allows private litigants affected by certain data breaches to recover significant statutory damages.  Although the 
CCPA exempts some data processed in the context of clinical trials, the CCPA increases compliance costs and potential liability with respect to other 
personal data we maintain about California residents.  In addition, the California Privacy Rights Act of 2020, or CPRA, expands the CCPA’s requirements, 
including by adding a new right for individuals to correct their personal information and establishing a new regulatory agency to implement and enforce the 
law.  Other states, such as Virginia, Colorado, Utah, and Connecticut have also passed comprehensive privacy laws, and similar laws are being considered 
in several other states, as well as at the federal and local levels. While these states, like the CCPA, also exempt some data processed in the context of 
clinical trials, these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom 
we rely.

With the GDPR, CCPA, CPRA, and other state and Federal laws, regulations and other obligations relating to privacy and data protection imposing new 
and relatively burdensome obligations, and with substantial uncertainty over the interpretation and application of these and other obligations, we may face 
challenges in addressing their requirements and making necessary changes to our policies and practices, and may incur significant costs and expenses in an 
effort to do so. Additionally, if third parties we work with, such as vendors or service providers, violate applicable laws or regulations or our policies, such 
violations may also put our or our customers’ data at risk and could in turn have an adverse effect on our business.

Additionally, a trend has continued of increased federal and state regulation of payments and transfers of value provided to healthcare professionals 
and/or entities. On February 8, 2013, the Centers for Medicare & Medicaid Services, or CMS, released its final rule implementing the Physician Payments 
Sunshine Act that imposes annual reporting requirements on certain manufacturers of drugs, devices, biologicals and medical supplies for payments and 
other transfers of value provided by them, directly or indirectly, to 

24

 
Table of Contents

physicians (defined to include doctors, dentists, optometrists, podiatrists, and chiropractors), other healthcare professionals (such as physicians assistants 
and nurse practitioners), and teaching hospitals, as well as ownership and investment interests held by physicians and their family members. Certain states 
also mandate implementation of commercial compliance programs, impose restrictions on pharmaceutical manufacturer and device manufacturer marketing 
practices, require registration of pharmaceutical sales representatives, require drug manufacturers to report information on the pricing of certain drugs, or 
require tracking and reporting of gifts, compensation and other remuneration to particular types of healthcare professionals and entities. 

Because of the breadth of these laws and the narrowness of the statutory exceptions and regulatory safe harbors available under such laws, it is 
possible that some of our current or future business activities, including certain clinical research, sales and marketing practices and the provision of certain 
items and services to our customers, could be subject to challenge under one or more of such laws. The heightening compliance environment and the need 
to build and maintain robust and expandable systems to comply with different compliance and/or reporting requirements in multiple jurisdictions could 
increase the possibility that a healthcare company may fail to comply fully with one or more of these requirements. If our operations are found to be in 
violation of any of the health care laws or regulations described above that are applicable to us, or any other laws that apply to us, we may be subject to 
penalties, including potentially significant criminal, civil and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion 
from participation in government healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, additional reporting 
requirements and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with 
these laws, 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, once approved, are sold in a foreign country, we may be subject to similar foreign laws, 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. 

Coverage and reimbursement 

The physicians who use XIPERE and our other product candidates, if approved, may be reimbursed by third-party payors for both the 

suprachoroidal injection using our SCS Microinjector and for the drug itself. On July 1, 2016, the American Medical Association, or AMA, approved a 
new Category III Current Procedural Terminology, or CPT, code for the suprachoroidal injection of pharmacologic agents. Category III codes are a set of 
temporary codes maintained by the AMA for emerging technology, services and procedures. Payment for these services or procedures are based on the 
coverage policies of individual third-party payors, including private insurers and government-funded programs, like Medicare, and Medicare administrative 
contractors. In November 2023, AMA assigned XIPERE the Category 1 CPT code 67516. We believe the Category 1 code may facilitate better access and 
adoption of XIPERE and the suprachoroidal injection method.

Our strategy will include efforts to engage third-party payors to establish coverage, coding and reimbursement that will facilitate access to XIPERE 

and our product candidates and the SCS injection procedure as we expand our commercialization efforts in the United States. Our success in these efforts 
depends in part on the extent to which third-party payors provide coverage and establish adequate reimbursement levels for the procedures during which 
XIPERE and our product candidates are administered and for the drugs themselves. Failure by physicians, hospitals, ambulatory surgery centers and other 
users of our products to obtain sufficient coverage and adequate reimbursement from third-party payors for the procedures to administer XIPERE and our 
product candidates or for XIPERE and the product candidates themselves, or adverse changes in third-party payors’ policies would have a material adverse 
effect on our business, financial condition, results of operations and future growth prospects. 

In the U.S., third-party payors continue to implement initiatives that restrict the use of certain technologies to those that meet certain clinical 

evidentiary requirements. Failure to obtain favorable coverage policies could have a material adverse effect on our business and operations. 

In addition to uncertainties surrounding coverage policies, third-party payors from time to time update reimbursement amounts and also revise the 

methodologies used to determine reimbursement amounts. This includes annual updates to payments to ambulatory surgery centers, hospitals and 
physicians for the procedures performed administering our products, which could directly impact the demand for XIPERE and any of our product 
candidates that may be approved. An example of payment updates is the Medicare program updates to physician payments, which is done on an annual 
basis using a prescribed statutory formula. In the past, when the application of the formula resulted in lower payment, Congress has passed interim 
legislation to prevent the reductions. However, the Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, ended the use of the statutory 
formula and established a quality payment program, also referred to as the Quality Payment Program. The quality payment program has two tracks, one 
known as the merit-based incentive payment system for providers in the fee-for service Medicare program, and the advanced alternative payment model for 
providers in specific care models, such as accountable care organizations. Under both Advanced Alternative Payment Models, or APMs, and Merit-based 
Incentive Payment System, or MIPS, performance data collected each performance year will affect Medicare payments in later years, including potentially 
reducing payments. In addition, beginning on January 1, 2023, certain 

25

Table of Contents

manufacturers will be required to pay quarterly refunds to CMS for discarded amounts of single-dose container and single-use package drugs covered 
under Medicare Part B. Refunds will be based on the discarded volume above 10% of the total allowed amount, except in unique circumstances as 
determined by CMS. Any changes in coverage and reimbursement that further restricts coverage of our products or lowers reimbursement for procedures 
using our products could materially affect our business. 

Healthcare reform 

Current and future legislative proposals to further reform healthcare or reduce healthcare costs may result in lower reimbursement for our products, 
or for the procedures associated with the use of our products, or limit coverage of our products. The cost containment measures that third-party payors and 
providers are instituting and the effect of any healthcare reform initiative implemented in the future could significantly reduce our revenues from the sale of 
our products. 

For example, implementation of the Affordable Care Act has the potential to substantially change healthcare financing and delivery by both 

governmental and private insurers, and significantly impact the pharmaceutical and medical device industries. 

The Affordable Care Act imposed, among other things, a new federal excise tax on the sale of certain medical devices, established an annual, 

nondeductible fee on any entity that manufactures or imports certain specified branded prescription drugs and biologic agents, addressed a new 
methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, 
instilled, implanted or injected, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended 
the Medicaid Drug Rebate program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations and provided incentives 
to programs that increase the federal government’s comparative effectiveness research. There have been judicial and Congressional challenges to certain 
aspects of the Affordable Care Act. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain 
taxes under the Affordable Care Act have been signed into law. Further, on June 17, 2021, the U.S. Supreme Court dismissed a challenge on procedural 
grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Prior to the U.S. 
Supreme Court ruling, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period from February 15, 2021 
through May 15, 2021 for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also 
instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, 
reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to 
obtaining access to health insurance coverage through Medicaid or the Affordable Care Act. On August 16, 2022, President Biden signed the Inflation 
Reduction Act of 2022, or IRA, into law, which, among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in 
Affordable Care Act marketplaces through plan year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 
by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is unclear any additional 
healthcare reform measures of the Biden administration will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. On August 2, 2011, President 
Obama signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction to recommend 
to Congress proposals in spending reductions. The Joint Select Committee did not achieve a targeted deficit reduction of at least $1.2 trillion for the years 
2013 through 2021, triggering the legislation’s automatic reduction to several government programs. This includes reductions to Medicare payments to 
providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent amendments, will remain in effect until 2032. On January 2, 
2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several 
providers, including hospitals, imaging centers and cancer treatment centers and increased the statute of limitations period for the government to recover 
overpayments to providers from three to five years. 

Further, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed 

products, which have resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, 
bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under 
Medicare, and reform government program reimbursement methodologies for drug products. At the federal level, in July 2021, the Biden administration 
released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to 
Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug 
pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to 
advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs 
and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not 
equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs 
and biologics covered under Medicare Part B 

26

Table of Contents

or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement many of these provisions through guidance, as 
opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 2023. On August 29, 2023, HHS announced the 
list of the first ten drugs that will be subject to price negotiation, although the Medicare drug price negotiation program is currently subject to legal 
challenges. It is unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden 
administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation 
Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the 
models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to 
control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of 
Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the 
first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not 
previously been exercised, it is uncertain if that will continue under the new framework. At the state level, legislatures have increasingly passed legislation 
and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, 
discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage 
importation from other countries and bulk purchasing.

The Foreign Corrupt Practices Act 

The Foreign Corrupt Practices Act, or the FCPA, prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering 

of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the 
foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed 
in the United States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all 
transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for 
international operations. Activities that violate the FCPA, even if they occur wholly outside the United States, can result in criminal and civil fines, 
imprisonment, disgorgement, oversight, and debarment from government contracts. 

Employees and Human Capital Resources

ITEM 1A. RISK FACTORS 

You should carefully consider the risks described below, as well as general economic and business risks and the other information in this Annual 

Report on Form 10-K. The occurrence of any of the events or circumstances described below or other adverse events could have a material adverse effect 
on our business, results of operations and financial condition and could cause the trading price of our common stock to decline. Additional risks or 
uncertainties not presently known to us or that we currently deem immaterial may also harm our business.

Risks Related to Our Financial Position and Capital Needs 

We have incurred significant losses since our inception. We expect to incur losses over the next several years and may never achieve or maintain 
profitability.  

We incurred a net loss of $32.5 million and $32.9 million, respectively, in 2023 and 2022. We expect to incur significant expenses and operating 

losses over the next several years. Our financial results may fluctuate significantly from quarter to quarter and year to year.

We have devoted substantially all of our financial resources and efforts to research and development, including preclinical studies and clinical trials.  

We anticipate that our expenses will increase substantially as we:  

•

•

•

•

•

•

conduct and complete our ongoing and planned clinical trials; 

seek to discover, research and develop additional product candidates; 

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

establish additional partnerships for the development and commercialization of our assets;

maintain, expand and protect our intellectual property portfolio; and

hire additional clinical, manufacturing and scientific personnel.

To become and remain profitable, we must succeed in developing drugs that can generate significant revenue once commercialized. This will require 
us to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our product candidates, manufacturing, 
obtaining regulatory approval and potentially entering into agreements for the commercialization of any products for which we may obtain regulatory 
approval, as well as discovering and developing additional product candidates. We are only in the preliminary stages of most of these activities. We may 
never succeed in these activities and, even if we do, may never generate sufficient revenue to achieve profitability.

Because of the numerous risks and uncertainties associated with drug development, we are unable to accurately predict the timing or amount of 
expenses or when, or if, we will be able to achieve profitability. If we are required by regulatory authorities to perform studies in addition to those currently 
expected, or if there are any delays in the initiation and completion of our clinical trials or the development of any of our product candidates, our expenses 
could increase. 

Even if we achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and 
remain profitable would depress our value and could impair our ability to raise capital, expand our business, maintain our research and development efforts, 
diversify our product offerings or continue our operations. A decline in our value could also cause you to lose all or part of your investment. 

We will need substantial additional funding to meet our financial obligations and to pursue our business objectives. If we are unable to raise capital 
when needed, we could be forced to delay, reduce or altogether cease our drug development programs or commercialization efforts. 

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements into the 

third quarter of 2025. However, we will need to obtain substantial additional funding in connection with our continuing operations beyond the third quarter 
of 2025, including additional funding to complete clinical development of CLS-AX. Our future capital requirements will depend on many factors, 
including:  

•

•

the progress and results of our ongoing, planned and future clinical trial programs; 

the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for our other product candidates; 

28

Table of Contents

•

•

•

•

•

•

•

the number and development requirements of other product candidates that we may pursue; 

the costs, timing and outcome of regulatory review of our product candidates; 

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our 
product candidates for which we receive marketing approval and intend to commercialize ourselves; 

the amount of revenue, if any, received pursuant to our license and collaboration agreements;

the amount of revenue, if any, received from commercial sales of any of our product candidates for which we receive marketing approval; 

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and 
defending any intellectual property-related claims; and 

the extent to which we acquire or in-license other product candidates and technologies. 

Identifying potential product candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process 
that takes years to complete, and we may never generate the necessary data or results required to obtain regulatory approval of our product candidates and 
achieve product sales. In addition, XIPERE and our other product candidates, if approved, may not achieve commercial success. Accordingly, we will need 
to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable 
terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have 
sufficient funds for our current or future operating plans. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, 
reduce or altogether cease our research and development programs or future commercialization efforts. 

Raising additional capital may cause dilution to our stockholders, restrict our operations or require us to relinquish rights to our technologies or 
product candidates. 

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity 

offerings, debt financings and potential collaboration, license and development agreements. For example, in February 2024, we completed a registered 
direct offering of 11,111,111 shares of common stock and accompanying warrants to purchase 11,111,111 shares of common stock for gross proceeds of 
approximately $15.0 million, before deducting placement agent fees and estimated offering expenses. We do not currently have any committed external 
source of funds, although as described in this report we have also entered into an at-the-market sales facility that allows us to sell shares of our common 
stock at prevailing market prices and on specified terms, depending on market conditions. To the extent that we raise additional capital through the sale of 
equity or convertible debt securities, your ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences 
that adversely affect your rights as a common stockholder. Debt financing and preferred equity 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 collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may 
be required to grant licenses on terms that may not be favorable to or relinquish valuable rights to our technologies, research programs, product candidates 
or future revenue streams. For example, we, through our wholly-owned subsidiary, sold our rights to receive certain royalty and milestone payments under 
the Arctic Vision License Agreement, Bausch License Agreement, the Aura License Agreement, the REGENXBIO Option and License Agreement and any 
out-license agreements for, or related to, XIPERE or our SCS Microinjector technology to be used in connection with compounds or products of any third 
parties in exchange for up to $65 million. 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 drug development efforts or future commercialization efforts or grant rights to develop and market product candidates 
that we would otherwise prefer to develop and market ourselves. 

Our agreements with HCR contain various covenants and other provisions, which, if violated, could materially adversely affect our financial condition.

In August 2022, we, through Royalty Sub, entered into the Purchase and Sale Agreement, with HCR pursuant to which we sold our rights to royalty 

and milestone payments due to us from XIPERE and certain license agreements related to our SCS Microinjector, or the Royalties, subject to a cap of 2.5 
times the total purchase price paid by HCR under the Purchase and Sale Agreement, which cap can be increased to 3.4 times under certain circumstances. 
Under the terms of the Purchase and Sale Agreement, Royalty Sub received an initial payment of $32.5 million, less certain expenses. The terms of the 
Purchase and Sale Agreement also provide for an additional $20 million milestone payment to Royalty Sub upon attainment of a second pre-specified sales 
milestone related to 2024 XIPERE sales.

In connection with the Purchase and Sale Agreement, we entered into a Contribution and Servicing Agreement with Royalty Sub, pursuant to which 

we assigned the Arctic Vision License Agreement, Bausch License Agreement, Aura License Agreement, REGENXBIO Option and License Agreement, 
our license agreement with Emory University and The Georgia Tech Research Corporation and related intellectual property rights, or collectively the 
Contributed Assets, to Royalty Sub. The Contribution and Servicing Agreement contains various representations and warranties, covenants, 
indemnification obligations and other provisions related to the contribution of the Contributed Assets and our maintenance and servicing obligations with 
respect to the same. 

In connection with the Purchase and Sale Agreement, we also entered into a Pledge and Security Agreement with HCR. The Pledge and Security 
Agreement contains various representations, warranties and covenants, and includes a limited recourse guaranty of Royalty Sub’s obligations under the 
Purchase and Sale Agreement which is secured by the pledge in favor of HCR all of the capital stock of Royalty Sub. HCR is entitled to foreclose on the 
capital stock of Royalty Sub following the occurrence of certain remedies events, including, without limitation, a bankruptcy of us, our failure of to 
perform our obligations under the Contribution and Servicing Agreement or in the event of a change of control of us, any failure to make the payment 
required under Section 2.3 of the Purchase and Sale Agreement within the time period required thereunder. Such foreclosure, if it were to occur, could have 
a material adverse effect on our financial condition as HCR, by virtue of owning Royalty Sub, would own the Royalties and the Contributed Assets.

Our business could be adversely affected by economic downturns, inflation, increases in interest rates, natural disasters, public health crises, political 
crises, geopolitical events, such as the conflicts in Ukraine and the Middle East, or other macroeconomic conditions.

The global economy, including credit and financial markets, has experienced extreme volatility and disruptions, including, among other things, 

severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, supply chain shortages, increases in 
inflation rates, higher interest rates and uncertainty about economic stability. In 2023, the Federal Reserve raised interest rates multiple times in response to 
concerns about inflation and it may raise them again. Higher interest rates, coupled with reduced government spending and volatility in financial markets 
may increase economic uncertainty and affect consumer spending. Similarly, the ongoing military hostilities in Russia, Ukraine and the Middle East have 
created extreme volatility in the global capital markets and is expected to have further global economic consequences, including disruptions of the global 
supply chain and energy markets. Any such volatility and disruptions may adversely affect our or our partners’ business. If the equity and credit markets 
deteriorate, including as a result of political unrest or war, it may make any necessary debt or equity financing more costly or more dilutive or more 
difficult to obtain in a timely manner or on favorable terms, if at all. Increased inflation rates can adversely affect us by increasing our costs, including 
clinical trials costs and labor and employee benefit costs.

Adverse developments affecting financial institutions, companies in the financial services industry or the financial services industry generally, such as 
actual events or concerns involving liquidity, defaults or non-performance, could adversely affect our operations and liquidity. 

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in 
the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may 
in the future lead to market-wide liquidity problems. 

Our access to our cash and cash equivalents in amounts adequate to finance our operations could be significantly impaired by the financial 
institutions with which we have arrangements directly facing liquidity constraints or failures. In addition, investor concerns regarding the U.S. or 
international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and 
operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on 
acceptable terms or at all. Any material decline in available funding or our ability to access our cash and cash equivalents could adversely impact our 
ability to meet our operating expenses, result in breaches of our contractual obligations or result in violations of federal or state wage and hour laws, any of 
which could have material adverse impacts on our operations and liquidity.

Risks Related to the Development of Our Product Candidates 

Our efforts are focused on the development of product candidates for treatment of eye disease through suprachoroidal injection and partnering with 
companies who can leverage our SCS Microinjector to deliver their ophthalmic product candidates to the SCS. Suprachoroidal injection is a novel 
approach and may fail to achieve and sustain market acceptance. 

Injecting drugs into the SCS is a novel approach for ophthalmic therapies, and there is no guarantee this approach will provide adequate patient 

benefit or be accepted by physicians, patients or third-party payors. We have also licensed our SCS Microinjector 

30

 
Table of Contents

technology to third parties to deliver their proprietary drug candidates into the SCS for the potential treatment of certain ocular indications. 

Although the FDA approved XIPERE for suprachoroidal use for the treatment of macular edema associated with uveitis, we cannot guarantee that 

suprachoroidal injection of other drugs will prove in ongoing and future clinical trials to be a safe or effective approach for treating eye diseases in humans, 
nor can we ensure that such other drugs will achieve regulatory approval, even if the clinical trials are successful. 

In addition, the novelty of suprachoroidal injection may make it difficult to demonstrate to physicians and third-party payors that suprachoroidal 

injection of drugs is an appropriate approach for treating eye diseases and provides advantages compared to the current standards of care. Further, if we or 
our commercialization and collaboration partners are not successful in conveying to physicians, patients and third-party payors that the suprachoroidal 
administration of drugs with our proprietary SCS Microinjector provides useful patient outcomes, we or our commercialization and collaboration partners 
may experience reluctance, or refusal, on the part of physicians to order and use, and third-party payors to cover and provide adequate reimbursement for, 
such drugs. Additionally, in some cases, drugs delivered using our SCS Microinjector will complement the current standard of care, rather than serve as a 
replacement for the current standard of care. Therefore, we or our commercialization and collaboration partners may encounter significant difficulty in 
gaining broad market acceptance by physicians, third-party payors and potential patients. 

Our licensing partners may require that we modify our SCS Microinjector to deliver their product candidates, and we may be unable to do so. 

We are currently partnering with companies who can leverage our SCS Microinjector to deliver their ophthalmic product candidates to the SCS. Our 

current and future licensing partners may request modifications to the design of our SCS Microinjector to accommodate the delivery of their respective 
product candidates. If we are unable to make such modifications, we may not receive regulatory and development milestone payments that we otherwise 
would be eligible to receive after we have satisfied our obligations under the Purchase and Sale Agreement, which could significantly harm our financial 
position.

If we are unable to obtain regulatory approval for, and commercialize either on our own or with a third party, CLS-AX or our other product candidates, 
or if we experience significant delays in doing so, our business may be harmed. 

Given our experience with our clinical programs, the successful development of any of our product candidates is extremely uncertain, and we cannot 
guarantee that we will be successful in developing any of our product candidates. Further, the FDA may conclude that our clinical trials are not sufficient to 
support approval of our product candidates. 

We have invested substantially all of our efforts and financial resources in the development of our proprietary SCS Microinjector for suprachoroidal 
injection of drugs and the identification of potential drug candidates using that technology. Our ability to generate revenue from our product candidates will 
depend heavily on their successful development and eventual commercialization, either by us or third parties. The success of those product candidates will 
depend on several factors, including the following: 

•

•

•

•

•

•

•

•

•

•

successful completion of preclinical studies and requisite clinical trials; 

performing preclinical studies and clinical trials in compliance with FDA requirements; 

receipt of marketing approvals from applicable regulatory authorities; 

ability to import sufficient quantity of product for trials or potential commercialization; 

obtaining marketing approvals with labeling for sufficiently broad patient populations and indications, without unduly restrictive distribution 
limitations or safety warnings, such as black box warnings or a risk evaluation and mitigation strategy, or REMS, program; 

obtaining and maintaining patent, trademark and trade secret protection and regulatory exclusivity for our product candidates; 

making arrangements with third-party manufacturers for, or establishing, commercial manufacturing capabilities; 

launching commercial sales of products, if and when approved, whether alone or in collaboration with others; 

successful training of physicians in the proper use of our SCS Microinjector; 

the ability to market our products for use with our SCS Microinjector without a requirement from the FDA that we obtain a separate medical 
device authorization; 

31

Table of Contents

•

•

•

•

•

acceptance of the therapies and of the concept of suprachoroidal injection of drugs, if and when approved, by physicians, patients and third-
party payors; 

competing effectively with other therapies; 

obtaining and maintaining healthcare coverage and adequate reimbursement from third-party payors; 

protecting our rights in our intellectual property portfolio; and 

maintaining a continued acceptable safety profile of the drugs and our SCS Microinjector following approval. 

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully 

commercialize our product candidates, which would materially harm our business. 

Data from our clinical trials that we announce or publish from time to time may change as more patient data become available, and such data are 
subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish data from our clinical trials. Data from clinical trials are subject to the risk that one or more of the clinical 
outcomes may materially change as patient enrollment continues and more patient data become available. Data also remain subject to audit and verification 
procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, data should be viewed 
with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our prospects 
for obtaining regulatory approval of our product candidates.

We may not be successful in our efforts to build a pipeline of product candidates. 

A key element of our strategy is to build a pipeline of product candidates for the treatment of a variety of diseases of the back of the eye via 
suprachoroidal injection and to progress these product candidates through developmental efforts. We may not be able to develop product candidates that are 
safe and effective. Even if we are successful in continuing to build our pipeline, the potential product candidates that we identify may not be suitable for 
clinical development, including as a result of being shown to have significant side effects or other characteristics that indicate that they are unlikely to 
receive marketing approval or achieve market acceptance. If we do not successfully develop product candidates based upon our approach, we will not be 
able to obtain product revenue in future periods, which could significantly harm our financial position and adversely affect our stock price. 

Clinical drug development involves a lengthy and expensive process with an uncertain outcome. We may incur additional costs or experience delays in 
completing, or ultimately be unable to complete, the development of our product candidates. 

The risk of failure for our product candidates is high. It is impossible to predict when or if CLS-AX or any of our product candidates will prove 

effective or safe in humans and will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any 
product candidate, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of our 
product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to 
outcome. A failure of one or more clinical trials can occur at any stage of testing.

The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials and interim results of a clinical 
trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many 
companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain 
marketing approval of their products.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing 

approval for our product candidates, including:  

•

•

•

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

we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with 
prospective trial sites; 

clinical trials of our product candidates may produce negative or inconclusive results, including failure to demonstrate statistical significance, 
and we may decide, or regulators may require us, to conduct additional clinical trials or abandon product development programs; 

32

Table of Contents

•

•

•

•

•

•

the number of patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials 
may be slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate; 

our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or 
at all; 

regulators may issue a clinical hold, or regulators or institutional review boards may require that we or our investigators suspend or terminate 
clinical research for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being 
exposed to unacceptable health risks; 

the cost of clinical trials of our product candidates may be greater than we anticipate; 

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

our product candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators or 
institutional review boards to suspend or terminate the trials. 

For example, our ODYSSEY trial was delayed due to the issuance by FDA of draft guidance, requiring us to reassess our original protocol design 

and we subsequently decided to amend the protocol to have aflibercept as the comparator drug.

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we 

are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are only 
modestly positive or if there are safety concerns, we may:  

•

•

•

•

•

•

be delayed in obtaining marketing approval for our product candidates; 

not obtain marketing approval at all; 

obtain approval for indications or patient populations that are not as broad as intended or desired; 

obtain approval with labeling that includes significant use or distribution restrictions or safety warnings, such as black box warnings or a 
REMS program; 

be subject to additional post-marketing testing requirements; or 

have the product removed from the market after obtaining marketing approval. 

Our drug development costs may also increase if we experience delays in testing or marketing approvals. We do not know whether any of our 

preclinical studies or clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant preclinical 
study or clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow 
our competitors to bring products to market before we do and impair our or our potential collaborators’ ability to successfully commercialize our product 
candidates. 

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or 
prevented. 

We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of 
eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. We cannot predict how 
successful we will be at enrolling patients in future clinical trials. In addition, if we are not successful at enrolling patients in one clinical trial, it may affect 
when we are able to initiate our next clinical trial, which could result in significant delays in our efforts to pursue regulatory approval of and commercialize 
our product candidates. In addition, some of our competitors have ongoing clinical trials to treat the same indications as our product candidates, and 
patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors. Patient enrollment is affected by other 
factors including: 

•

•

•

•

•

the severity of the disease under investigation; 

the eligibility criteria for the study in question; 

the perceived risks and benefits of the product candidate under study; 

the availability of drugs approved to treat the diseases under study; 

the efforts to facilitate timely enrollment in clinical trials; 

33

Table of Contents

•

•

•

the patient referral practices of physicians; 

the ability to monitor patients adequately during and after treatment; and 

the proximity and availability of clinical trial sites for prospective patients. 

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 
cause our value to decline and limit our ability to obtain additional financing. 

If serious adverse or unacceptable side effects are identified during the development of our product candidates, we may need to abandon or limit our 
development of some of our product candidates. 

If our product candidates are associated with side effects in clinical trials or have characteristics that are unexpected, we may need to abandon their 
development or limit development to more narrow uses or subpopulations in which the side effects or other characteristics are less prevalent, less severe or 
more acceptable from a risk-benefit perspective. Many product candidates that initially showed promise in early-stage testing have later been found to 
cause side effects that prevented further development of the product candidate. In addition, in some cases, the FDA could issue a clinical hold to stop the 
study. 

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications 
that may be more profitable or for which there is a greater likelihood of success. 

Because we have limited financial and management resources, we focus on research programs and product candidates that we identify for specific 

indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have 
greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial drugs or profitable market 
opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any 
commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may 
relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been 
more advantageous for us to retain sole development and commercialization rights to such product candidate. 

Risks Related to Our Dependence on Third Parties 

We have granted an exclusive license to Bausch for the commercialization and development of XIPERE in the United States and Canada. After we 
have satisfied our obligations under the Purchase and Sale Agreement, if we are unable to maintain our partnership with Bausch, or if Bausch fails to 
successfully commercialize XIPERE, our business and prospects will be materially harmed.

We have granted an exclusive license to Bausch for the commercialization and development of XIPERE in the United States and Canada. Pursuant 

to our agreement with Bausch, we are entitled to receive payments based on the achievement of specified sales and regulatory milestones and tiered 
royalties based on annual net sales of XIPERE. We will not retain these royalties and milestone payments until our obligations under the Purchase and Sale 
Agreement described above in “Business—Royalty Purchase and Sale Agreement” are satisfied. The successful or timely achievement of many of these 
milestones is outside of our control because the relevant activities will be conducted by Bausch or third parties engaged by Bausch, including 
manufacturers and suppliers. We expect to depend to a large degree on the payments from Bausch after we have satisfied our obligations under the 
Purchase and Sale Agreement as well as payments from future potential commercialization partners in order to fund our operations, and a failure to receive 
such payments may cause us to:

•

•

•

•

•

•

delay, reduce or terminate certain research and development programs;

reduce headcount;

pursue the raising of additional funds through equity or convertible debt financings that could be dilutive to our stockholders;

seek funds by entering into agreements that require us to assign rights to technologies or products that we would have otherwise retained; 

enter into new arrangements that may be less favorable than those we would have obtained under different circumstances; or 

consider strategic transactions or engaging in a joint venture with a third party.

34

Table of Contents

We have entered into, and intend to continue to enter into, collaborations with third parties for the development and commercialization of XIPERE. In 
addition, we may seek commercialization partners for our product candidates. If those collaborations are not successful, we may not be able to 
capitalize on the market potential of XIPERE and our product candidates. 

We have entered into, and intend to continue to enter into, agreements with third-party collaborators for the development and commercialization of 

XIPERE and our product candidates. Our likely collaborators for any collaboration arrangements include large and mid-size pharmaceutical companies, 
regional and national pharmaceutical companies and smaller biotechnology companies. Our ability to generate revenues from these arrangements will 
depend on our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. 

Collaborations involving XIPERE and our product candidates would pose the following risks to us:  

•

•

•

•

•

•

•

•

•

•

•

•

•

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

collaborators may not perform their obligations as expected;

collaborators may refuse to perform clinical trials or other obligations required for approval in a particular jurisdiction outside the United 
States; 

our collaborators’ regulatory submissions may be denied by the applicable regulatory authorities;

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

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

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

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

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

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

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

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

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

Collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If a 
present or future collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our drug development or 
commercialization program could be delayed, diminished or terminated. 

35

Table of Contents

We rely on third parties to conduct our clinical trials for our product candidates, and those third parties may not perform satisfactorily, including 
failing to meet deadlines for the completion of such trials or failing to comply with applicable regulatory requirements. 

We have engaged contract research organizations, or CROs, for our ongoing and planned clinical trials. We also expect to engage CROs for any of 

our other product candidates that may progress to clinical development. We expect to rely on CROs, as well as other third parties, such as clinical data 
management organizations, medical institutions and clinical investigators, to conduct those clinical trials. Agreements with such third parties might 
terminate for a variety of reasons, including a failure to perform by the third parties. If we need to enter into alternative arrangements, that would delay our 
drug development activities. 

Our reliance on these third parties for research and development activities will reduce our control over these activities but will not relieve us of our 

responsibilities. For example, we will remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general 
investigational plan and protocols for the trial. Moreover, the FDA requires us to comply with regulatory standards, commonly referred to as Good Clinical 
Practices, or GCPs, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and 
that the rights, integrity and confidentiality of trial participants are protected. We also are required to register certain ongoing clinical trials and post the 
results of certain completed clinical trials on a government-sponsored database, ClinicalTrials.gov, within specified timeframes. Failure to do so by us or 
third parties can result in FDA refusal to approve applications based on the clinical data, enforcement actions, adverse publicity and civil and criminal 
sanctions. 

Furthermore, these third parties may also have relationships with other entities, some of which may be our competitors. If these third parties do not 

successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our 
stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or 
may be delayed in our or our potential collaborators’ efforts to, successfully commercialize our product candidates. 

In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and may receive cash 

or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of 
interest, or the FDA concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the 
applicable clinical trial site may be questioned and the utility of the clinical trial itself may be jeopardized, which could result in the delay or rejection by 
the FDA of any NDA we submit. Any such delay or rejection could prevent the commercialization of our current or future product candidates. 

We also expect to rely on other third parties to store and distribute product supplies for our clinical trials. Any performance failure or regulatory 

noncompliance on the part of our distributors could delay clinical development or marketing approval of our product candidates or commercialization of 
our products, producing additional losses and depriving us of potential product revenue. 

We do not have our own manufacturing capabilities and rely on third parties to produce clinical and commercial supplies of our current product 
candidates and our SCS Microinjector. This reliance on third parties increases the risk that we will not have sufficient quantities of our drug products 
and our SCS Microinjector, or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization 
efforts. 

We do not have any manufacturing facilities or personnel. We currently procure the active pharmaceutical ingredient of our product candidates on a 

purchase order basis from a third-party manufacturer, but we do not have a commercial supply agreement in place with that manufacturer. In addition, we 
have entered into a supply agreement with Gerresheimer, our SCS Microinjector supplier. Some of our current suppliers are based outside of the United 
States. In addition, some of the facilities of our third-party manufacturers have only undergone a limited number of FDA inspections or no inspections.  We 
expect to continue to rely on third parties as we proceed with preclinical and clinical studies using our SCS Microinjector, as well as for commercial 
manufacture, for any of our product candidates that receive marketing approval. This reliance on third parties increases the risk that we will not have 
sufficient quantities of our drug products including our SCS Microinjector or such quantities at an acceptable cost or quality, which could delay, prevent or 
impair our ability to timely conduct our clinical trials or our other development or commercialization efforts. In addition, we may be unable to establish any 
agreements with third-party manufacturers or collaborators or to do so on acceptable terms. 

Reliance on third-party manufacturers or collaborators entails additional risks, including:  

•

•

reliance on the third party for regulatory compliance and quality assurance;

the possible breach of the manufacturing agreement by the third party;

36

Table of Contents

•

•

the possible misappropriation of our proprietary information, including our trade secrets and know-how; and

the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

Our product candidates, including our proprietary drug formulations packaged together with our SCS Microinjector, are subject to the drug 
regulations of the FDCA. Third-party manufacturers may not be able to comply with current Good Manufacturing Practices, or cGMP, regulations, 
regulations applicable to drug/device combination products, including applicable provisions of the FDA’s drug cGMP regulations, device cGMP 
requirements embodied in the Quality System Regulation, or QSR, or similar regulatory requirements outside the United States. Our failure, or the failure 
of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, a refusal to 
file determination by the FDA, receipt of a CRL, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, 
seizures or recalls of product candidates, operating restrictions and criminal prosecutions, any of which could significantly affect our ability to achieve 
regulatory approval of our product candidates. 

Our product candidates that we may develop may compete with other drugs and devices for access to manufacturing facilities. There are a limited 

number of manufacturers that operate under the drug and device cGMP regulations applicable to our product candidates and that might be capable of 
manufacturing for us. Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. 
We do not currently have arrangements in place for redundant supply or a second source for bulk drug substance or our SCS Microinjector. If our current 
contract manufacturers cannot perform as agreed, we may be required to replace such manufacturers. Although we believe that there are several potential 
alternative manufacturers who could manufacture our drugs and the components of our SCS Microinjector, we may incur added costs and delays in 
identifying and qualifying any such replacement. For example, the FDA could require supplemental data if a new supplier is relied upon for the supply of 
our products. Any interruption or delay in the supply of components and materials, or our inability to obtain components or materials from alternate sources 
at acceptable prices in a timely manner, could impair our ability to meet the demand of our customers and cause them to cancel orders. 

Our current and anticipated future dependence upon others for the manufacture of our product candidates may compromise our future profit 

margins and/or our commercialization partner's ability to commercialize any product candidates that receive marketing approval on a timely and 
competitive basis. 

If we are not able to establish additional collaborations, we may have to alter some of our future development and commercialization plans. 

Our drug development programs and the potential commercialization of our product candidates will require substantial additional cash to fund 
expenses. For some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies for the future development 
and potential commercialization of those product candidates. 

We face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, 
among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the 
proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by 
the FDA or similar regulatory authorities outside the United States, the potential market for the subject product candidate, the costs and complexities of 
manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our 
ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market 
conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to 
collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under 
existing license agreements from entering into agreements on certain terms with potential collaborators. Collaborations are complex and time-consuming to 
negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that 
have resulted in a reduced number of potential future collaborators. 

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the 

development of such product candidate, reduce or delay its development program or one or more of our other development programs, delay its potential 
commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization 
activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to 
obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further 
develop our product candidates or bring them to market and generate product revenue.

Risks Related to the Commercialization of Our Product Candidates 

If we are unable to establish sales and distribution capabilities for our product candidates for which we do not out-license commercialization rights, we 
may not be successful in commercializing those product candidates, if and when they are approved. 

We do not have a sales infrastructure. To achieve commercial success for any product candidate for which we may obtain marketing approval in the 

United States and have not licensed the commercialization rights to a third party, we will need to establish a sales organization. There are risks involved 
with establishing our own sales and distribution capabilities. For example, recruiting and training a sales force is expensive and time-consuming and could 
delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force is delayed or does not occur for any reason, we 
would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot 
retain or reposition our sales and marketing personnel. 

Factors that may inhibit our efforts to commercialize our drugs on our own include:  

•

•

•

•

our inability to recruit, train and retain adequate numbers of effective sales and marketing personnel; 

the inability of sales personnel to obtain access to physicians or educate an adequate number of physicians as to the benefits of our product 
candidates; 

the lack of complementary drugs to be offered by sales personnel, which may put us at a competitive disadvantage compared to companies 
with more extensive product lines; and 

unforeseen costs and expenses associated with creating an independent sales and marketing organization. 

If we are unable to establish our own sales and distribution capabilities and, instead, enter into arrangements with third parties to perform these 
services, our product revenues and our profitability, if any, are likely to be lower than if we were to sell and distribute any product candidates that we 
develop ourselves. In addition, we may not be successful in entering into arrangements with third parties to sell and distribute our product candidates or 
may be unable to do so on terms that are favorable to us. We likely will have little control over such third parties, and any of them may fail to devote the 
necessary resources and attention to sell and market our product candidates effectively. If we do not establish sales and distribution capabilities 
successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates. 

XIPERE and any of our product candidates that receive marketing approval, may fail to achieve the degree of market acceptance by physicians, 
patients, third-party payors and others in the medical community necessary for commercial success. 

XIPERE and any of our product candidates that receive marketing approval may nonetheless fail to gain sufficient market acceptance by physicians, 

patients, third-party payors and others in the medical community. Suprachoroidal injection of drugs is a novel approach and physicians, patients or third-
party payors may be hesitant to deviate from or change the current standard of care. If XIPERE or our product candidates do not achieve an adequate level 
of market acceptance, we may not generate significant product revenue and we may not become profitable. The degree of market acceptance of XIPERE 
and our product candidates, if approved for commercial sale, will depend on a number of factors, including:  

•

•

•

•

•

•

•

•

•

•

•

the efficacy and potential advantages compared to alternative treatments; 

our ability to offer our drugs for sale at competitive prices; 

the convenience and ease of administration compared to alternative treatments; 

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

the willingness of the healthcare community and patients to adopt new technologies and our novel approach of SCS injection of drugs; 

the willingness of uveitis and retina specialists to expend the time necessary to receive proper training on injecting drugs into the SCS using 
our SCS Microinjector; 

the ability to manufacture our products in sufficient quantities and yields; 

the strength of marketing and distribution support provided by us or our collaborators; 

the availability of third-party payor coverage and adequate reimbursement; 

the prevalence and severity of any side effects; and 

any restrictions on the use of our drugs together with other medications.

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

The development and commercialization of new products is highly competitive. We face competition with respect to our current product candidates 

and will face competition with respect to any product candidates that we may seek to develop or commercialize in the future, from major pharmaceutical 
companies, specialty pharmaceutical companies and biotechnology companies worldwide. We also are aware of companies that are developing 
suprachoroidal injectors which may compete with our SCS Microinjector. 

With respect to XIPERE, we face competition from other commercially available forms of TA and other injectable and implantable corticosteroids. 
Bristol-Myers Squibb markets TA under the brand name Kenalog, for which a number of generic equivalents are currently available. Kenalog is indicated 
only for intramuscular or intraarticular injection; however, it is commonly used off-label for intraocular inflammation using intravitreal and periocular 
administration. In addition, Alcon’s injectable TA, Triesence, is approved in the United States for the treatment of uveitis and other ocular inflammatory 
conditions unresponsive to topical corticosteroids, although it is not indicated for the treatment of macular edema associated with uveitis. Ozurdex, 
marketed by Allergan, is a bioerodable extended release implant that delivers the corticosteroid dexamethasone and is approved for the treatment of non-
infectious uveitis affecting the posterior segment of the eye and for macular edema due to RVO in both the United States and in the European Union. 
Ozurdex is also approved in the United States for the treatment of DME. Retisert and Yutiq, both intravitreal implants of fluocinolone acetonide, are 
marketed by Bausch and Alimera, respectively, and are approved in the United Sates for the treatment of chronic non-infectious uveitis affecting the 
posterior segment of the eye.

CLS-AX faces competition with anti-VEGF drugs, the current standard of care for RVO and wet AMD, as well as other drug candidates in 

development for ocular use for the treatment of wet AMD, such as other TKI’s. Axitinib, also known by its brand name Inlyta, is not currently approved for 
an ocular indication but is approved by the FDA and marketed by Pfizer for the treatment of advanced renal cell carcinoma. Genentech has several products 
which serve as competitors in this space, including anti-VEGF agents Lucentis, Avastin, and Susvimo. Lucentis is currently approved in the United States 
and European Union for the treatment of wet AMD, macular edema following RVO, and diabetic retinopathy in patients with DME. Avastin is an anti-
VEGF drug routinely used off-label by uveitis and retina specialists in both the United States and in certain countries of the European Union for the 
treatment of numerous retinal diseases. Susvimo, an ocular implant that releases ranibizumab over time, received approval from the FDA in October 2021 
for the treatment of wet AMD in patients who have previously responded to anti-VEGF therapy.  Additionally, Genentech’s product, Vabysmo (faricimab-
svoa), an intravitreal injection which blocks two disease pathways, including (Ang-2) and vascular endothelial growth factor-A (VEGF-A), received 
approval in January 2022 for the treatment of wet AMD and diabetic macular edema. In addition to Genentech’s products, Regeneron’s anti-VEGF product, 
Eylea 2 mg and 8 mg and Novartis’ product, Beovu, also present potential competition for CLS-AX in both the United States and Europe.  Eylea is 
approved for the treatment of wet AMD, macular edema following RVO and diabetic retinopathy and DME in the United States and for the treatment of 
wet AMD, RVO and DME in the European Union. Novartis’ Beovu was approved in 2019 for the treatment of wet AMD in the United States and in 2020 
in Europe. 

Ocular drug candidates being investigated for treatment of wet AMD may also represent potential competition for CLS-AX.   Ocular Therapeutics 

and Eyepoint are companies currently investigating TKIs for ocular use in late-stage clinical trials. We expect other established companies will seek to 
develop new products in the ocular space with the goal of superior efficacy and duration over the current standard of care. 

REGENXBIO, Adverum, and 4D Molecular Therapeutics are currently conducting mid to late-stage clinical trials with various  ocular gene 

therapies for the treatment of wet AMD.  These gene-based treatments could potentially compete with CLS-AX due to their potential to be long acting 
treatments.  

The SCS Microinjector faces competition from other devices being developed to access ocular posterior tissues via the SCS. Oxular Limited and 

Everads both have developed competing products and are in various stages of early-stage clinical development

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, 
have fewer or less severe side effects, are more convenient or are less expensive than any product candidates that we may develop. Our competitors also 
may obtain FDA or other regulatory approval for their product candidates more rapidly than we may obtain approval for ours, which could result in product 
approval delays if a competitor obtains market exclusivity from the FDA or our competitors establishing a strong market position before we or our 
collaborators are able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking 
to encourage the use of generic drugs. For some of the indications that we are pursuing, drugs used off-label, such as Kenalog and Avastin, serve as cheaper 
alternatives to our product candidates. Their lower prices could result in significant pricing pressure, even if our product candidates are otherwise viewed as 
a preferable therapy. Additional drugs may become available on a generic basis over the coming years. If our product candidates achieve marketing 
approval, we expect that they will be priced at a significant premium over competitive generic drugs.

Many of the companies against which we are competing or against which we may compete in the future have significantly greater financial 

resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and 
marketing approved drugs than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources 
being concentrated among a smaller number of our competitors. Smaller and other early-stage companies may also prove to be significant competitors, 
particularly through collaborative arrangements with large and established companies. These third parties compete with us in recruiting and retaining 
qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies 
complementary to, or necessary for, our programs. 

XIPERE and our product candidates may be subject to unfavorable pricing regulations, third-party coverage and reimbursement policies or healthcare 
reform initiatives. 

Our and our collaborators’ ability to commercialize XIPERE and any of our product candidates successfully will depend, in part, on the extent to 

which coverage and adequate reimbursement for XIPERE and our product candidates will be available from government payor programs at the federal and 
state levels, including Medicare and Medicaid, private health insurers, managed care plans and other third-party payors. Government authorities and other 
third-party payors, such as private health insurers and health maintenance organizations, decide which medical products they will pay for and establish 
reimbursement levels. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and 
are challenging the prices charged for drugs and products. Coverage and reimbursement may not be available and, even if these are available, the level of 
reimbursement may not be satisfactory. Inadequate reimbursement levels may adversely affect the demand for, or the price of, any product candidate for 
which we obtain marketing approval. Obtaining and maintaining coverage and adequate reimbursement for our drugs may be difficult. We or our 
collaborators may be required to conduct expensive pharmacoeconomic studies to justify coverage and reimbursement or the level of reimbursement 
compared to other therapies. If coverage and adequate reimbursement are not available or reimbursement is available only to limited levels, we or our 
collaborators may not be able to successfully commercialize XIPERE and any other product candidates for which marketing approval is obtained. 

A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have 
attempted to control costs by limiting coverage and the amount of reimbursement for particular medical products. By way of example, the Medicare 
Prescription Drug Improvement and Modernization Act of 2003, or MMA, changed the way Medicare covers and pays for pharmaceutical products. The 
legislation expanded Medicare coverage for outpatient drug purchases by those covered by Medicare under a new Part D program and introduced a new 
reimbursement methodology based on average sales prices for Medicare Part B physician-administered drugs, including drugs currently on the market used 
by physicians to treat the clinical indications for which we are currently seeking FDA approval and likely XIPERE and our other product candidates, if 
approved. As a result of this legislation and the expansion of federal coverage of drug products, there is additional pressure to contain and reduce costs. 
While the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in 
setting their own reimbursement rates, and any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from 
private payors. These cost reduction initiatives and other provisions of the MMA could decrease the coverage and reimbursement that we receive for any 
approved products and could seriously harm our business. 

Further, from time to time, typically on an annual basis, payment amounts are updated and revised by third-party payors. Because we expect that 
customers who use XIPERE and our other product candidates, if approved, will be separately reimbursed for the procedure administering our products, 
these updates could directly impact the demand for our products. An example of payment updates is the Medicare program updates to physician payments, 
which is done on an annual basis using a prescribed statutory formula. In the past, when the application of the formula resulted in lower payment, Congress 
has passed interim legislation to prevent the reductions. However, the Medicare Access and CHIP Reauthorization Act of 2015, or MACRA, ended the use 
of the statutory formula, also referred to as the Sustainable Growth Rate, for clinician payment and established a quality payment incentive program, also 
referred to as the Quality Payment Program. This program provides clinicians with two ways to participate, including through the Advanced Alternative 
Payment Models, or APMs, and the Merit-based Incentive Payment System, or MIPS. Under both APMs and MIPS, performance data collected each 
performance year will affect Medicare payments in later years, including potentially reducing payments. Any reduction in reimbursement from Medicare or 
other government programs may result in a similar reduction in payments from private payors. We cannot predict how pending and future healthcare 
legislation will impact our business, and any changes in coverage and reimbursement that further restricts coverage of our products or lowers 
reimbursement for procedures using our products could materially affect our business.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the 

indications for which the product is approved by the FDA or similar regulatory authorities outside the United States. Moreover, eligibility for coverage and 
reimbursement does not imply that a product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, 
sale and distribution expenses. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be 
made permanent. 

40

Table of Contents

We believe that physicians who use XIPERE and our other product candidates, if approved, may be reimbursed by third-party payors for both the 
suprachoroidal injection using our SCS Microinjector and for the drug itself. On July 1, 2016, the American Medical Association, or AMA, approved a 
new Category III Current Procedural Terminology, or CPT, code for the suprachoroidal injection of pharmacologic agents. Category III codes are a set of 
temporary codes maintained by the AMA for emerging technology, services and procedures. Payment for these services or procedures are based on the 
coverage policies of individual payors, including private insurers and government-funded programs, like Medicare, and Medicare administrative 
contractors. CPT code 0465T became effective on January 1, 2017. In November 2023, AMA assigned XIPERE the Category 1 CPT code 67516. We 
believe the Category 1 code may facilitate better access and adoption of XIPERE and the suprachoroidal injection method. Additionally, there is no 
guarantee that these billing codes or the payment amounts, if any, associated with such codes will be sufficient to successfully commercialize any approved 
product and, even if adequate payment amounts are obtained, they could change in the future. 

Reimbursement rates may vary according to the use of the product and the clinical setting in which it is used, may be based on reimbursement levels 

already set for lower cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory 
discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of 
drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and 
payment limitations in setting their own reimbursement policies. However, no uniform policy requirement for coverage and reimbursement for drug 
products exists among third-party payors in the United States. Therefore, coverage and reimbursement can differ significantly from payor to payor. As a 
result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the 
use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained at all. 
Additionally, coverage policies and reimbursement rates may change at any time. For example, beginning on January 1, 2023, certain manufacturers will be 
required to pay quarterly refunds to CMS for discarded amounts of single-dose container and single-use package drugs covered under Medicare Part B. 
Refunds will be based on the discarded volume above 10% of the total allowed amount, except in unique circumstances, as determined by CMS. Our or our 
collaborators’ inability to promptly obtain coverage and adequate reimbursement rates from both government-funded and private payors for any approved 
drugs that we develop could significantly harm our operating results, our ability to raise capital and our overall financial condition. Further, any changes in 
coverage and reimbursement that further restricts coverage of our products or lowers reimbursement for procedures using our products could materially 
affect our business.

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

and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining 
approvals. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins 
after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing 
governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then 
be subject to price regulations that delay commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues able to be 
generated from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in XIPERE and one or 
more product candidates, even if our other product candidates obtain marketing approval. 

There can be no assurance that XIPERE and our other product candidates, if they are approved for sale in the United States or in other countries, 

will be considered medically reasonable and necessary for a specific indication, that they will be considered cost-effective by third-party payors, that 
coverage or an adequate level of reimbursement will be available, or that third-party payors’ reimbursement policies will not adversely affect our ability to 
sell XIPERE and our other product candidates profitably if they are approved for sale. 

Product liability lawsuits against us could cause us to incur substantial liabilities.

We face an inherent risk of product liability exposure related to the sale of XIPERE as well as the testing of our product candidates in human clinical 
trials. If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. 
Regardless of merit or eventual outcome, liability claims may result in:  

•

•

•

•

•

decreased demand for any product candidates or products that we may develop; 

injury to our reputation and significant negative media attention; 

withdrawal of clinical trial participants; 

significant costs to defend the related litigation; 

substantial monetary awards paid to trial participants or patients; 

41

Table of Contents

•

•

•

loss of revenue; 

reduced resources of our management to pursue our business strategy; and 

our or our collaborators’ inability to commercialize any drugs that we may develop. 

We currently hold $10.0 million in product liability insurance coverage in the aggregate, with a per incident limit of $10.0 million, which may not be 

adequate to cover all liabilities that we may incur. We may need to increase our insurance coverage as we expand our clinical trials or if we or our 
collaborators commence commercialization of our product candidates. Insurance coverage is increasingly expensive. We may not be able to maintain 
insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise. 

Risks Related to Employee Matters and Managing Our Growth 

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel. 

We are highly dependent on the management, research and development, clinical, financial and business development expertise of our executive 

officers and senior management, as well as the other members of our scientific and clinical development teams. Our executive officers may terminate their 
employment with us at any time. We do not maintain “key person” insurance for any of our executives or employees. 

Recruiting and retaining qualified scientific and clinical personnel will also be critical to our success. The loss of the services of our executive 

officers or other key employees could impede the achievement of our objectives and seriously harm our ability to successfully implement our business 
strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited 
number of individuals in our industry with the breadth of skills and experience required to successfully develop and gain regulatory approval of our product 
candidates. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable 
terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the 
hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific 
and clinical advisors, to assist us in formulating our strategy. Our consultants and advisors may have commitments under consulting or advisory contracts 
with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our 
growth strategy will be limited. 

Risks Related to Our Intellectual Property 

If we are unable to obtain and maintain patent protection for our technology and product candidates, or if our licensors are unable to obtain and 
maintain patent protection for the technology or product candidates that we license from them, or if the scope of the patent protection obtained is not 
sufficiently broad, our competitors could develop and commercialize technology and drugs similar or identical to ours, and our ability to successfully 
commercialize our technology and product candidates may be impaired. 

Our success depends in large part on our and our licensors’ ability to obtain and maintain patent protection in the United States and other countries 
with respect to our product candidates. We and our licensors seek to protect our proprietary position by filing patent applications in the United States and 
abroad related to our technology and product candidates. 

The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent 

applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development 
output before it is too late to obtain patent protection or that we have published an invention prior to filing a relevant patent application. We may not have 
the right to control the preparation, filing and prosecution of patent applications, or to maintain the rights to patents licensed to third parties. For example, 
we do not control the prosecution of the patent applications licensed to us under the Emory/GT License described below. Therefore, these patents and 
applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. If such licensors fail to maintain such 
patents, or lose rights to those patents, the rights we have licensed may be reduced or eliminated. 

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and 
has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of 
the United States or visa-versa. For example, European patent law restricts the patentability of methods of treatment of the human body more than United 
States law does. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States 
and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot know with certainty 
whether we were the first to make 

42

Table of Contents

the inventions claimed in our owned or licensed patents or pending patent applications, or that we were the first to file for patent protection of such 
inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future 
patent applications may not result in patents being issued that protect our technology or product candidates, in whole or in part, or which effectively prevent 
others from commercializing competitive technologies and drugs. Changes in either the patent laws or interpretation of the patent laws in the United States 
and other countries may diminish the value of our patents or narrow the scope of our patent protection. 

Recent patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the 

enforcement or defense of our issued patents. On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. 
The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way patent applications 
are prosecuted, redefine prior art and may also affect patent litigation. The United States Patent and Trademark Office recently developed new regulations 
and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, 
and in particular, the first to file provisions, only became effective on March 16, 2013. Accordingly, it is not clear what, if any, impact the Leahy-Smith Act 
will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding 
the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could significantly harm our business and 
financial condition. In addition, patent reform legislation may pass in the future that could lead to additional uncertainties and increased costs surrounding 
the prosecution, enforcement and defense of our owned and licensed patents and patent applications. 

Moreover, we may be subject to a third-party preissuance submission of prior art to the U.S. Patent and Trademark Office, or become involved in 

opposition, derivation, reexamination, inter partes review, post-grant review or interference proceedings challenging our patent rights or the patent rights of 
others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third 
parties to commercialize our technology or drugs and compete directly with us, without payment to us, or result in our inability to manufacture or 
commercialize drugs without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent 
applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product 
candidates. 

Even if our owned and licensed patent applications issue as patents, they may not issue in a form that will provide us with any meaningful protection 

and may not be of sufficient scope or strength to provide us with any commercial advantage. Our competitors may be able to design around our owned or 
licensed patents by developing similar or alternative technologies or drugs without infringing on our intellectual property rights. 

In addition, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, and our owned and licensed patents may 

be challenged in the courts or patent offices in the United States and abroad. Such challenges may result in loss of exclusivity or freedom to operate or in 
patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or 
commercializing similar or identical technology and drugs, or limit the duration of the patent protection of our technology and drugs. Given the amount of 
time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or 
shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude 
others from commercializing drugs similar or identical to ours, and our business will suffer. 

Changes in U.S. patent law or the patent law of other countries or jurisdictions could diminish the value of patents in general, thereby impairing our 
ability to protect our products. 

The United States has enacted and implemented 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 actions by the U.S. Congress, the federal courts and the USPTO, the laws and regulations governing 
patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce patents that we have licensed or that we 
might obtain in the future. For example, recent decisions raise questions regarding the award of patent term adjustment, or PTA, for patents in families 
where related patents have issued without PTA. Thus, it cannot be said with certainty how PTA will or will not be viewed in future and whether patent 
expiration dates may be impacted. Similarly, changes in patent law and regulations in other countries or jurisdictions or changes in the governmental bodies 
that enforce them or changes in how the relevant governmental authority enforces patent laws or regulations may weaken our ability to obtain new patents 
or to enforce patents that we have licensed or that we may obtain in the future. For example, the complexity and uncertainty of European patent laws have 
also increased in recent years. In Europe, a new unitary patent system will likely be introduced by the end of 2023, which would significantly impact 
European patents, including 

43

 
Table of Contents

those granted before the introduction of such a system. Under the unitary patent system, European applications will soon have the option, upon grant of a 
patent, of becoming a Unitary Patent which will be subject to the jurisdiction of the Unitary Patent Court (UPC). As the UPC is a new court system, there is 
no precedent for the court, increasing the uncertainty of any litigation. Patents granted before the implementation of the UPC will have the option of opting 
out of the jurisdiction of the UPC and remaining as national patents in the UPC countries. Patents that remain under the jurisdiction of the UPC will be 
potentially vulnerable to a single UPC-based revocation challenge that, if successful, could invalidate the patent in all countries who are signatories to the 
UPC.  We cannot predict with certainty the long-term effects of any potential changes.

We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and 
unsuccessful. 

Competitors may infringe our issued patents or other intellectual property. To counter infringement or unauthorized use, we may be required to file 
infringement claims, which can be expensive and time consuming. Any claims we assert against perceived infringers could provoke these parties to assert 
counterclaims against us alleging that we infringe their patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is 
invalid or unenforceable, in whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on 
the grounds that our patents do not cover the technology. An adverse result in any litigation proceeding could put one or more of our patents at risk of being 
invalidated or interpreted narrowly, which would undermine our competitive position. 

Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain 
and could significantly harm business. 

Our commercial success depends upon our ability, and the ability of any collaborators, to develop, manufacture, market and sell our product 
candidates and use our proprietary technologies without infringing the proprietary rights of third parties. There is considerable intellectual property 
litigation in the biotechnology and pharmaceutical industries. In particular, we are focused on developing product candidates based on widely used 
therapeutic agents, many of which are protected by proprietary rights of third parties, and we are developing proprietary formulations of these therapeutic 
agents specifically for suprachoroidal injection using our proprietary SCS Microinjector. Although we seek to develop our proprietary drug formulations 
that don’t infringe the intellectual property rights of others, we may become party to, or threatened with, future adversarial proceedings or litigation 
regarding intellectual property rights with respect to our drugs or other aspects of our technology, including interference or derivation proceedings before 
the U.S. Patent and Trademark Office. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in 
the future. 

If we are found to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue 

developing and marketing our technology and drugs. However, we may not be able to obtain any required license on commercially reasonable terms or at 
all. Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We 
could be forced, including by court order, to cease commercializing the infringing technology or product. In addition, we could be found liable for 
monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could 
prevent us from commercializing our product candidates or force us to cease some of our business operations. 

Competing products may be sold in countries in which our patent coverage might not exist or be as strong. If we lose a patent lawsuit alleging our 

infringement of a competitor’s patent, or if FDA approval is stayed pending the outcome of patent litigation, we could be prevented from marketing our 
products. As a result, our ability to grow our business and compete in the market may be harmed. 

Intellectual property litigation could cause us to spend substantial resources and distract our personnel from their normal responsibilities. 

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses 

and could distract our technical and management personnel from their normal responsibilities. In addition, there could be public announcements of the 
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could 
hurt the price of our common stock. Such litigation or proceedings could substantially 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 sustain the costs of such litigation or proceedings more effectively than we 
can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could 
compromise our ability to compete in the marketplace.

If we fail to comply with our obligations under our existing intellectual property licenses with third parties, we could lose license rights that are 
important to our business. 

We are a party to a license agreement with Emory University and Georgia Tech Research Corporation, or the Emory/GT License, and may enter into 

additional license agreements in the future. Our existing license agreement imposes, and we expect that future license agreements would impose, various 
diligence, milestone payment, royalty, insurance and other obligations on us. For example, under the Emory/GT License, we are required to use 
commercially reasonable efforts to develop and commercialize licensed products under the agreement and to satisfy other specified obligations, including 
the payment of license fees and minimum royalty payments. If we fail to comply with our obligations under our license agreements, our licensors may have 
the right to terminate these license agreements, in which event we might not be able to market any product that is covered by these agreements, or to 
convert the license to a non-exclusive license, which could impair the value of the product candidate being developed under the license agreement. 
Termination of these license agreements or reduction or elimination of our licensed rights may result in our having to negotiate new or reinstated licenses 
with less favorable terms. If our licensors under the Emory/GT License were to terminate their license agreement with us for any reason, we would lose 
access to critical technology related to our SCS Microinjector. 

We may need to license additional intellectual property from third parties, and such licenses may not be available or may not be available on 
commercially reasonable terms. 

A third party may hold intellectual property rights, including patent rights, that are important or necessary to the development of our product 

candidates. It may be necessary for us or our collaborators to use the patented or proprietary technology of third parties to commercialize our product 
candidates, in which case we would be required to obtain a license from these third parties. Such a license may not be available on commercially 
reasonable terms, or at all, and we could be forced to cease development of one or more or our product candidates or accept unfavorable contractual terms. 
If we are unable to obtain such licenses on commercially reasonable terms, our business could be harmed. 

We may be subject to claims by third parties asserting that we or our employees have misappropriated their intellectual property, or claiming ownership 
of what we regard as our own intellectual property. 

Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies. Although we try to ensure 

that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these employees or 
we have inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, of any such employee’s 
former employer. We may also in the future be subject to claims that we have caused an employee to breach the terms of his or her non-competition or non-
solicitation agreement. Litigation may be necessary to defend against these potential claims. 

In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property to 

execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who in fact 
develops intellectual property that we regard as our own. Our and their assignment agreements may not be self-executing or may be breached, and we may 
be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual 
property. 

If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or 

personnel. A court could prohibit us from using technologies or features that are essential to our products, if such technologies or features are found to 
incorporate or be derived from the trade secrets or other proprietary information of the former employers. Even if we are successful in prosecuting or 
defending against such claims, litigation could result in substantial costs and could be a distraction to management. In addition, any litigation or threat 
thereof may adversely affect our ability to hire employees or contract with independent service providers. Moreover, a loss of key personnel or their work 
product could hamper or prevent our or our collaborators’ ability to commercialize our product candidates. 

Any trademarks we may obtain may be infringed or successfully challenged, resulting in harm to our business. 

We expect to rely on trademarks as one means to distinguish any of our product candidates that are approved for marketing from the products of our 

competitors. Other than the trade name XIPERE, we have not yet selected trademarks for our product candidates or begun the process of applying to 
register trademarks for our product candidates. Once we select trademarks and apply to register them, our trademark applications may not be approved. In 
addition, third parties may oppose our trademark applications, or otherwise challenge our use of the trademarks. If our trademarks are successfully 
challenged, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devote resources to 
advertising and marketing new brands. Our competitors may infringe our trademarks and we may not have adequate resources to enforce our trademarks.

Some intellectual property that we have in-licensed may have been discovered through a government funded program and may be subject to certain 
federal regulations.

Some of the intellectual property rights we have licensed, including such rights licensed from Emory University and Georgia Tech Research 

Corporation, may have been generated through the use of U.S. government funding and may therefore be subject to certain federal regulations. As a result, 
the U.S. government may have certain rights to intellectual property embodied in our current or future product candidates pursuant to the Bayh-Dole Act of 
1980, or Bayh-Dole Act. These U.S. government rights in certain inventions developed under a government-funded program include a non-exclusive, non-
transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government may have the right to require 
us to grant exclusive, partially exclusive or non-exclusive licenses to any of these inventions to a third party if it determines that: (i) adequate steps have not 
been taken to commercialize the invention, (ii) government action is necessary to meet public health or safety needs or (iii) government action is necessary 
to meet requirements for public use under federal regulations (also referred to as “march-in rights”). The U.S. government also could take title to these 
inventions if we, or the applicable licensor, fail to disclose the invention to the government and fail to file an application to register the intellectual property 
within specified time limits. Intellectual property generated under a government funded program is also subject to certain reporting requirements, 
compliance with which may require us or the applicable licensor to expend substantial resources. In addition, the U.S. government requires that any 
products embodying the subject invention or produced through the use of the subject invention be manufactured substantially in the United States. The 
manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been 
made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the 
circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. 
product manufacturers for products covered by such intellectual property. To the extent any of our current or future intellectual property is generated 
through the use of U.S. government funding, the provisions of the Bayh-Dole Act may similarly apply.

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

In addition to seeking patent and trademark protection for our product candidates, we also rely on trade secrets, including unpatented know-how, 

technology and other proprietary information, to maintain our competitive position. We seek to protect our trade secrets, in part, by entering into non-
disclosure and confidentiality agreements with parties who have access to them, such as our employees, corporate collaborators, outside scientific 
collaborators, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment 
agreements with our employees and consultants. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary 
information, including our trade secrets. Monitoring unauthorized uses and disclosures of our intellectual property is difficult, and we do not know whether 
the steps we have taken to protect our intellectual property will be effective. In addition, we may not be able to obtain adequate remedies for any such 
breaches. 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 United States are less willing or unwilling to protect trade secrets. 

Moreover, our competitors may independently develop knowledge, methods and know-how equivalent to our trade secrets. Competitors could 
purchase our products and replicate some or all of the competitive advantages we derive from our development efforts for technologies on which we do not 
have patent protection. 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, or those to whom they communicate it, 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. 

Risks Related to Regulatory Approval of Our Product Candidates and Other Legal Compliance Matters 

If we are not able to obtain, or if there are delays in obtaining, required regulatory approvals, we and our collaborators will not be able to 
commercialize our product candidates, and our ability to generate revenue will be materially impaired. 

Our product candidates and the activities associated with their development and commercialization, including their design, research, testing, 

manufacture, safety, efficacy, quality control, recordkeeping, labeling, packaging, storage, approval, advertising, promotion, sale, distribution, import, 
export, and reporting of safety and other post-market information, are subject to comprehensive regulation by the FDA and other regulatory agencies in the 
United States and by the European Medicines Agency, or EMA, and similar regulatory authorities outside the United States. Failure to obtain marketing 
approval for a product candidate will prevent us, or any collaborator to whom we grant rights, from commercializing the product candidate. We expect to 
rely on third-party CROs to assist us in preparing some or all aspects of the applications necessary to gain marketing approvals. Securing marketing 
approval requires the submission of extensive preclinical and clinical data and supporting information to regulatory authorities for each therapeutic 
indication to establish the product candidate’s safety and efficacy. Securing marketing approval also requires the 

46

Table of Contents

submission of information about the product manufacturing process to, and inspection of manufacturing facilities by, the regulatory authorities. Our product 
candidates may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other 
characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use. If any of our product candidates receives marketing 
approval, the accompanying label may limit its approved use, which could limit sales of the product. 

The process of obtaining marketing approvals, both in the United States and abroad, is expensive and may take many years, if approval is obtained 

at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Changes in 
marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory 
review for each submitted product application, may cause delays in the approval or rejection of an application. Regulatory authorities have substantial 
discretion in the approval process and may refuse to accept any application or may decide that our data is insufficient for approval and require additional 
preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or 
prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval 
commitments that render the approved product not commercially viable. 

If we experience delays in obtaining approval or if we fail to obtain approval of our product candidates, the commercial prospects for our product 

candidates may be harmed and our ability to generate revenues will be materially impaired. 

If the FDA does not conclude that a product candidate satisfies the requirements for the Section 505(b)(2) regulatory approval pathway, or if the 
requirements under Section 505(b)(2) are not as we expect, the approval pathway for our product candidates in this pathway will likely take 
significantly longer, cost significantly more and entail significantly greater complications and risks than anticipated, and in either case may not be 
successful.

We believe that certain of our product candidates, including our proprietary drug formulations packaged together with our SCS Microinjector, will 

be regulated under the drug provisions of the FDCA, enabling us to submit NDAs for approval of our product candidates. The Drug Price Competition and 
Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Amendments, added Section 505(b)(2) to the FDCA. Section 505(b)(2) permits the 
filing of an NDA where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the 
applicant has not obtained a right of reference.

If the FDA does not allow us to pursue the Section 505(b)(2) regulatory pathway for a product candidate as anticipated, we may need to conduct 

additional clinical trials, provide additional data and information and meet additional standards for regulatory approval. If this were to occur, the time and 
financial resources required to obtain FDA approval for our product candidates, and complications and risks associated with our product candidates, would 
likely substantially increase. We may need to obtain additional funding, which could result in significant dilution to the ownership interests of our then 
existing stockholders to the extent we issue equity securities or convertible debt. We cannot assure you that we would be able to obtain such additional 
financing on terms acceptable to us, if at all.

Moreover, inability to pursue the Section 505(b)(2) regulatory pathway could result in competitive products reaching the market before our product 

candidates, which could impact our competitive position and prospects. Even if we are allowed to pursue the Section 505(b)(2) regulatory pathway, we 
cannot assure you that our product candidates will receive the requisite approvals for commercialization, or that a competitor would not obtain approval 
first, including subsequent market exclusivity from the FDA, thereby delaying potential approval of our product.

In addition, notwithstanding the approval of a number of products by the FDA under Section 505(b)(2) over the last few years, some pharmaceutical 

companies and others have objected to the FDA’s interpretation of Section 505(b)(2). If the FDA’s interpretation of Section 505(b)(2) is successfully 
challenged, the FDA may be required to change its Section 505(b)(2) policies and practices, which could delay or even prevent the FDA from approving 
any NDA that we submit under Section 505(b)(2).

Additional time may be required to obtain regulatory approval for our product candidates because of the complexity involved with co-packaging a drug-
device combination product. 

Our product candidates require coordination within the FDA and similar foreign regulatory agencies for review of the drug along with the SCS 

Microinjector. Although the FDA and similar foreign regulatory agencies have systems in place for the review and approval of combination products such 
as ours, we may experience delays in the development and commercialization of our product candidates due to regulatory timing constraints and 
uncertainties in the product development and approval process. In addition, to date, the FDA has not requested a separate medical device authorization 
submission for our SCS Microinjector. However, the FDA may request a separate medical device authorization submission for our SCS Microinjector in 
the future, which could delay the 

47

Table of Contents

development and commercialization of our product candidates. Additionally, other jurisdictions may have additional requirements for any drug and device 
combination, which may cause delays in product approval. 

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

In order to market and sell our products in the European Union and any other jurisdictions, we must obtain separate marketing approvals and comply 

with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing or requirements. 
The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the 
United States generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is 
required that the product be approved for reimbursement before the product can be approved for sale in that country. We may not obtain approvals from 
regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other 
countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other 
countries or jurisdictions or by the FDA. However, failure to obtain approval in one jurisdiction may impact our ability to obtain approval elsewhere. We 
may not be able to file for marketing approvals and may not receive necessary approvals in order for us or our collaborators to commercialize our products 
in any market. 

A variety of risks associated with marketing our product candidates internationally could affect our business. 

We may seek regulatory approval for our product candidates outside of the United States and, accordingly, we expect that we will be subject to 

additional risks related to operating in foreign countries if we obtain the necessary approvals, including:  

•

•

•

•

•

•

•

•

•

•

•

•

differing regulatory requirements in foreign countries; 

the potential for so-called parallel importing, which is what happens when a local seller, faced with high or higher local prices, opts to import 
goods from a foreign market with low or lower prices rather than buying them locally; 

unexpected changes in tariffs, trade barriers, price and exchange controls and other regulatory requirements; 

economic weakness, including inflation, or political instability in particular foreign economies and markets; 

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; 

foreign taxes, including withholding of payroll taxes; 

foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other obligations incident to 
doing business in another country; 

differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;

difficulties staffing and managing foreign operations; 

workforce uncertainty in countries where labor unrest is more common than in the United States; 

potential liability under the Foreign Corrupt Practices Act of 1977 or comparable foreign regulations; 

challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect 
intellectual property rights to the same extent as the United States; 

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and 

business interruptions resulting from geo-political actions, including war and terrorism. 

These and other risks associated with our international operations may compromise our ability to achieve or maintain profitability. 

We are subject to U.S. and certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and 
regulations.  Compliance with these legal standards could impair our ability to compete in domestic and international markets.  We can face criminal 
liability and other serious consequences for violations, which can harm our business.

We are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, 
various  economic  and  trade  sanctions  regulations  administered  by  the  U.S.  Treasury  Department’s  Office  of  Foreign  Assets  Controls,  the  U.S.  Foreign 
Corrupt  Practices  Act  of  1977,  as  amended,  or  FCPA,  the  U.S.  domestic  bribery  statute  contained  in  18  U.S.C.  §  201,  the  U.S.  Travel  Act,  the  USA 
PATRIOT Act, and other state and national anti-bribery and anti-money 

48

Table of Contents

laundering laws in the countries in which we conduct activities.  Anti-corruption laws are interpreted broadly and prohibit companies and their employees, 
agents, contractors, and other collaborators from authorizing, promising, offering, or providing, directly or indirectly, improper payments or anything else 
of value to recipients in the public or private sector.  We may engage third parties to sell our products outside the United States, to conduct clinical trials, 
and/or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals.  We have direct or indirect interactions with officials and 
employees of government agencies or government-affiliated hospitals, universities, and other organizations.  We can be held liable for the corrupt or other 
illegal activities of our employees, agents, contractors, and other collaborators, even if we do not explicitly authorize or have actual knowledge of such 
activities.  Any violations of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the 
loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences.

Any product candidate for which we obtain marketing approval could be subject to post-marketing restrictions or recall or withdrawal from the market, 
and we may be subject to penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product 
candidates, when and if any of them are approved. 

Any product candidate for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, 

advertising and promotional activities for such product, will be subject to continual requirements of and review by the FDA and other regulatory 
authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, 
cGMP requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements 
regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be 
subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including the requirement to implement 
a REMS, which could involve requirements for, among other things, a medication guide, special training for prescribers and dispensers, and patient 
registries. If any of our product candidates receives marketing approval, the accompanying label may limit its approved uses, which could limit sales of the 
product, or include a black box warning to highlight a specific health risk. 

The FDA may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the 

product. The FDA closely regulates the post-approval marketing and promotion of products to ensure products are marketed only for the approved 
indications and in accordance with the provisions of the approved labeling. Physicians, on the other hand, may prescribe products for off-label uses. 
Although the FDA and other regulatory agencies do not regulate a physician’s choice of drug treatment made in the physician’s independent medical 
judgment, they do restrict promotional communications from companies or their sales force with respect to off-label uses of products for which marketing 
clearance has not been issued. However, companies may share truthful and not misleading information that is otherwise consistent with the product’s FDA 
approved labeling. The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we do not market our drugs 
for their approved indications, we may be subject to enforcement action for off-label marketing. Violations of the FDCA relating to the promotion of 
prescription drugs may lead to investigations alleging violations of federal and state healthcare fraud and abuse laws, such as the federal civil False Claims 
Act, as well as state consumer protection laws.

In addition, later discovery of previously unknown adverse events or other problems with our drugs, including device malfunctions, manufacturers 

or manufacturing processes, or failure to comply with regulatory requirements, may have negative consequences, including:  

•

•

•

•

•

•

•

•

•

•

•

restrictions on such drugs, manufacturers or manufacturing processes; 

restrictions on the labeling or marketing of a drug; 

restrictions on drug distribution or use; 

requirements to conduct post-marketing studies or clinical trials; 

warning letters; 

recall or withdrawal of the drugs from the market; 

refusal to approve pending applications or supplements to approved applications that we submit; 

clinical holds; 

safety alerts; 

fines, restitution or disgorgement of profits or revenues; 

suspension or withdrawal of marketing approvals; 

49

Table of Contents

•

•

•

refusal to permit the import or export of our drugs; 

product seizure; or 

injunctions or the imposition of civil or criminal penalties. 

Non-compliance with European Union requirements regarding safety monitoring, or pharmacovigilance, and with requirements related to the 
development of drugs for the pediatric population, can also result in significant financial penalties. Similarly, failure to comply with the European Union’s 
requirements regarding the protection of personal information can also lead to significant penalties and sanctions. 

Even though we have received orphan drug designation in the European Union for the treatment of non-infectious uveitis, we may not be able to 
obtain orphan drug marketing exclusivity for this product candidate. 

Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively small patient 

populations as orphan drugs. We have received orphan drug designation from the EMA for the treatment of non-infectious uveitis, and we may seek orphan 
drug designation from the FDA or EMA for our future product candidates. However, we cannot pursue orphan drug designation from the FDA for the 
treatment of uveitis. 

Regulation (EC) No 141/2000 and Regulation (EC) No 847/2000 provide that a product can be designated as an orphan medicinal product by the 

European Commission if its sponsor can establish: that the product is intended for the diagnosis, prevention or treatment of (1) a life-threatening or 
chronically debilitating condition affecting not more than five in ten thousand persons in the European Union when the application is made, or (2) a life-
threatening, seriously debilitating or serious and chronic condition in the European Union and that without incentives the medicinal product is unlikely to 
be developed. For either of these conditions, the applicant must demonstrate that there exists no satisfactory method of diagnosis, prevention or treatment 
of the condition in question that has been authorized in the European Union or, if such method exists, the medicinal product will be of significant benefit to 
those affected by that condition. Once authorized, orphan medicinal products are entitled to ten years of market exclusivity in all EU Member States and in 
addition a range of other benefits during the development and regulatory review process including scientific assistance for study protocols, authorization 
through the centralized marketing authorization procedure covering all member countries and a reduction or elimination of registration and marketing 
authorization fees. However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the ten-year 
period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan 
medicinal product is unable to supply sufficient quantities. Marketing authorization may also be granted to a similar medicinal product with the same 
orphan indication if this product is safer, more effective or otherwise clinically superior to the original orphan medicinal product. In addition, the period of 
market exclusivity may be reduced to six years if it can be demonstrated based on available evidence that the original orphan medicinal product is 
sufficiently profitable not to justify maintenance of market exclusivity. There is no guarantee that we will be able to obtain or maintain orphan exclusivity 
even if we receive marketing authorization in Europe. 

Our employees, independent contractors, principal investigators, CROs, consultants, commercial partners and vendors may engage in misconduct or 
other improper activities, including non-compliance with regulatory standards and requirements. 

We are exposed to the risk of employee fraud or other misconduct or failure to comply with applicable regulatory requirements. Misconduct by 
employees and independent contractors, such as principal investigators, CROs, consultants, commercial partners and vendors, could include failures to 
comply with FDA regulations, to provide accurate information to the FDA, to comply with manufacturing standards we have established, to comply with 
federal and state healthcare fraud and abuse laws, to report financial information or data accurately or to disclose unauthorized activities to us. In particular, 
sales, marketing and other business arrangements in the healthcare industry are subject to extensive laws intended to prevent fraud, kickbacks, self-dealing 
and other abusive practices. These laws may restrict or prohibit a wide range of business activities, including research, manufacturing, distribution, pricing, 
discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Employee and independent 
contractor misconduct could also involve the improper use of individually identifiable information, including, without limitation, information obtained in 
the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. In addition, federal procurement laws impose 
substantial penalties for misconduct in connection with government contracts and require certain contractors to maintain a code of business ethics and 
conduct. It is not always possible to identify and deter employee and independent contractor misconduct, and any precautions we take to detect and prevent 
improper activities 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. If any such actions are instituted against us, those actions could have a 
significant impact on our business, including the imposition of substantial civil, criminal and administrative penalties, damages, monetary fines, 
disgorgement, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, 
imprisonment, diminished profits and future earnings, additional reporting requirements and/or oversight if we become subject to a corporate integrity 
agreement or 

50

Table of Contents

similar agreement to resolve allegations of non-compliance with these laws, and curtailment or restructuring of our operations, any of which could 
adversely affect our ability to operate. 

Our current and future relationships with healthcare professionals, principal investigators, consultants, customers and third-party payors in the United 
States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, physician payment transparency, 
health information privacy and security and other healthcare laws and regulations, which could expose us to penalties. 

Healthcare providers, including physicians, and third-party payors in the United States and elsewhere will play a primary role in the 

recommendation and prescription of any product candidates for which we obtain marketing approval. Our current and future arrangements with healthcare 
professionals, principal investigators, consultants, customers and third-party payors may expose us to broadly applicable fraud and abuse and other 
healthcare laws, including, without limitation, the federal Anti-Kickback Statute and the federal civil False Claims Act, that may constrain the business or 
financial arrangements and relationships through which we research, sell, market and distribute any product candidates for which we obtain marketing 
approval. In addition, we may be subject to physician payment transparency laws and patient privacy and security regulation by the federal government and 
by the states and foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws (including privacy and 
cybersecurity laws and regulations) that may affect our ability to operate include the following:  

•

•

•

•

•

•

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving 
or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual 
for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in 
part, under federal and state healthcare programs such as Medicare and Medicaid; 

federal civil and criminal false claims laws, including, without limitation, the federal civil False Claims Act which  permits private 
individuals, on behalf of the government, to bring civil whistleblower or qui tam actions to enforce the law, prohibits individuals or entities 
from, among other things, knowingly presenting, or causing to be presented, to the federal government, including federal health care 
programs, such as, the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, 
decrease or conceal an obligation to pay money to the federal government; 

the civil monetary penalties statute, which imposes penalties against any person or entity who, among other things, is determined to have 
presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that 
was not provided as claimed or is false or fraudulent; 

the Health Insurance Portability and Accountability Act, or HIPAA, which created additional federal civil and criminal statutes that prohibit 
knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false 
or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any 
healthcare benefit program, regardless of whether the payor is public or private, knowingly and willfully embezzling or stealing from a health 
care benefit program, willfully obstructing a criminal investigation of a health care offense and knowingly and willfully falsifying, 
concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, 
or payment for, healthcare benefits, items or services relating to healthcare matters;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2019, or HITECH, and their respective 
implementing regulations, which impose obligations on “covered entities,” including certain healthcare providers, health plans, and 
healthcare clearinghouses, as well as their respective “business associates” that create, receive, maintain or transmit individually identifiable 
health information for or on behalf of a covered entity and their subcontractors that use, disclose, access, or otherwise process individually 
identifiable health information, with respect to safeguarding the privacy, security and transmission of individually identifiable health 
information; 

the Physician Payments Sunshine Act, created under Section 6002 of the Patient Protection and Affordable Care Act, as amended by the 
Health Care and Education Reconciliation Act of 2010, or collectively, the Affordable Care Act, imposed annual reporting requirements for 
certain manufacturers of drugs, devices, biologics and medical supplies for certain payments and “transfers of value” provided to physicians 
(defined to include doctors, dentists, optometrists, podiatrists, and chiropractors), other healthcare professionals (such as physicians assistants 
and nurse practitioners), and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family 
members; 

analogous state and foreign laws, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and 
claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state and 
foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the 
relevant compliance guidance promulgated by the

federal government or to adopt compliance programs as prescribed by state laws and regulations, or that otherwise restrict payments that may 
be made to healthcare providers; state and foreign laws that require drug manufacturers to report information related to payments and other 
transfers of value to physicians and other healthcare providers or marketing expenditures; state and local laws requiring the registration of 
pharmaceutical sales representatives; and state and foreign laws governing the privacy and security of health information in certain 
circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating 
compliance efforts; 

U.S. data privacy regulations, such as the CCPA, which creates new individual privacy rights for consumers and places increased privacy and 
security obligations on entities handling personal data of consumers or households.  The CCPA requires covered companies to provide new 
disclosures to California consumers, provides such consumers new ways to opt-out of certain sales of personal information, and allows for a 
new cause of action for data breaches;

new U.S. data privacy regulations, such as the California Privacy Rights Act of 2020, or CPRA, which establishes a new California Privacy 
Protection Agency to implement and enforce the CPRA.  Other states, such as Virginia, Colorado, Utah, and Connecticut have also passed 
comprehensive privacy laws that have or will go into effect during 2023, and similar laws are being considered in several other states, as well 
as at the federal and local levels. While these new state laws, like the CCPA, also exempt some data processed in the context of clinical trials, 
these developments further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom we 
rely. If we become subject to new data privacy laws, at the state level, the risk of enforcement action against us could increase because we 
may become subject to additional obligations, and the number of individuals or entities that can initiate actions against us may increase 
(including individuals, via a private right of action, and state actors);

foreign data privacy regulations, such as the General Data Protection Regulation (2016/679), or GDPR, which applies to identified or 
identifiable personal data in electronic or paper form.  Under the GDPR, fines of up to €20.0 million or up to 4% of the annual global turnover 
of the infringer, whichever is greater, could be imposed for significant non-compliance.  The GDPR includes more stringent operational 
requirements for processors and controllers of personal data and creates additional rights for data subjects, including a private right of action. 
Also under the EU GDPR, companies may face temporary or definitive bans on data processing and other corrective actions. Other such 
foreign data privacy obligations include the EU GDPR as it forms part of United Kingdom, or UK, law by virtue of section 3 of the European 
Union (Withdrawal) Act 2018, or UK GDPR; and

In the ordinary course of business, we may transfer personal data from Europe and other jurisdictions to the United States or other countries. 
Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In 
particular, the European Economic Area (EEA) and the United Kingdom (UK) have significantly restricted the transfer of personal data to the 
United States and other countries whose privacy laws it believes are inadequate.  Other jurisdictions may adopt similarly stringent 
interpretations of their data localization and cross-border data transfer laws.  Although there are currently various mechanisms that may be 
used to transfer personal data from the EEA and UK to the United States in compliance with law, such as the EEA and UK’s standard 
contractual clauses, these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to 
lawfully transfer personal data to the United States.  If there is no lawful manner for us to transfer personal data from the EEA, the UK or 
other jurisdictions to the United States, or if the requirements for a legally-compliant transfer are too onerous, we could face significant 
adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data 
processing activities to other jurisdictions at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the 
inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of 
personal data necessary to operate our business.   Additionally, companies that transfer personal data out of the EEA and UK to other 
jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activist groups. 

Further, the Affordable Care Act, among other things, amended the intent requirement of the federal Anti-Kickback Statute and the healthcare fraud 

statute. A person or entity no longer needs to have actual knowledge of these statutes or specific intent to violate them in order to have committed a 
violation. In addition, the Affordable Care Act provided that the government may assert that a claim including items or services resulting from a violation 
of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. 

Efforts to ensure that our future business arrangements with third parties will comply with applicable healthcare laws and regulations may involve 

substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, 
regulations or case law involving applicable fraud and abuse or other healthcare laws. If our operations are found to be in violation of any of these laws or 
any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, including, without 
limitation, damages, fines, imprisonment, disgorgement, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, 
additional reporting requirements and/or oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of 

52

Table of Contents

non-compliance with these laws, and the curtailment or restructuring of our operations, as well as reputational harm, which could significantly harm our 
business. If any of the physicians or other healthcare providers or entities with whom we expect to do business, including future collaborators, are found 
not to be in compliance with applicable laws, they may be subject to the same criminal, civil and administrative sanctions, including exclusions from 
participation in government healthcare programs, which could also affect our business. 

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product 
candidates and affect the prices we may obtain. 

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding 

the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our 
ability to profitably sell any product candidates for which we obtain marketing approval. 

Among policy makers and payors in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with 

the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a 
particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, President Obama signed into law the 
Affordable Care Act, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance 
remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the 
health industry and impose additional health policy reforms. 

The Affordable Care Act among other things, increased the minimum level of Medicaid rebates payable by manufacturers of brand name drugs; 
required collection of rebates for drugs paid by Medicaid managed care organizations; required manufacturers to participate in a coverage gap discount 
program, under which they must agree to offer point-of-sale discounts (increased to 70 percent, effective as of January 1, 2019) off negotiated prices of 
applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under 
Medicare Part D; imposed a non-deductible annual fee on pharmaceutical manufacturers or importers who sell certain “branded prescription drugs” to 
specified federal government programs, implemented a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate 
Program are calculated for drugs that are inhaled, infused, instilled, implanted, or injected expanded the types of entities eligible for the 340B drug discount 
program; expanded eligibility criteria for Medicaid programs; created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, 
and conduct comparative clinical effectiveness research, along with funding for such research; and established a Center for Medicare Innovation at CMS to 
test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending.

There have been judicial and congressional challenges to certain aspects of the Affordable Care Act. On June 17, 2021 the U.S. Supreme Court 

dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was 
repealed by Congress. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order to initiate a special 
enrollment period for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also instructs 
certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, 
reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to 
obtaining access to health insurance coverage through Medicaid or the Affordable Care Act. The Affordable Care Act may be subject to additional judicial 
or Congressional challenges in the future. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which, 
among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in Affordable Care Act marketplaces through plan 
year 2025. The IRA also eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary 
maximum out-of-pocket cost and creating a new manufacturer discount program. It is unclear how any additional healthcare reform measures of the Biden 
administration will impact the Affordable Care Act and our business. 

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. These changes included aggregate 

reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and, due to subsequent legislative 
amendments, will stay in effect through 2032, unless additional Congressional action is taken. Additionally, on March 11, 2021, President Biden signed the 
American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average 
manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. In January 2013, President Obama signed into law 
the American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several providers, and increased the statute 
of limitations period for the government to recover overpayments to providers from three to five years. These new laws may result in 

53

Table of Contents

additional reductions in Medicare and other healthcare funding, which could negatively impact customers for our product candidates, if approved, and, 
accordingly, our financial operations. 

Further, there has been heightened governmental scrutiny recently over the manner in which drug manufacturers set prices for their marketed 

products, which have resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, 
bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under 
Medicare, and reform government program reimbursement methodologies for drug products. At the federal level, in July 2021, the Biden administration 
released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to 
Biden’s executive order, on September 9, 2021, the Department of Health and Human Services, or HHS, released a Comprehensive Plan for Addressing 
High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to 
advance these principles. In addition, the IRA, among other things, (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs 
and biologics covered under Medicare, and subject drug manufacturers to civil monetary penalties and a potential excise tax by offering a price that is not 
equal to or less than the negotiated “maximum fair price” for such drugs and biologics under the law, and (ii) imposes rebates with respect to certain drugs 
and biologics covered under Medicare Part B or Medicare Part D to penalize price increases that outpace inflation. The IRA permits HHS to implement 
many of these provisions through guidance, as opposed to regulation, for the initial years. These provisions take effect progressively starting in fiscal year 
2023. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the Medicare drug price 
negotiation program is currently subject to legal challenges. It is unclear how the IRA will be implemented but is likely to have a significant impact on the 
pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining 
three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and 
improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the 
Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On 
December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering 
the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in 
rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.  At the state level, 
legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including 
price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, 
in some cases, designed to encourage importation from other countries and bulk purchasing. 

We expect that other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and other 

healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any 
approved product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from 
private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain 
profitability, or commercialize our drugs. 

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for drugs. 
We cannot be sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or 
what the impact of such changes on the marketing approvals of our product candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress 
of the FDA’s approval process may significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-
marketing testing and other requirements.

Governments outside the United States tend to impose strict price controls, which may affect our revenue, if any. 

In some countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. 
In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To 
obtain coverage and reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost-
effectiveness of our product candidate to other available therapies. If reimbursement of our drugs is unavailable or limited in scope or amount, or if pricing 
is set at unsatisfactory levels, our business could be harmed, possibly materially.

Risks Related to Ownership of Our Common Stock 

The trading price of the shares of our common stock may be volatile, and purchasers of our common stock could incur substantial losses. 

Our stock price has been and may continue to be volatile. The stock market in general and the market for biopharmaceutical companies in particular 

have experienced extreme volatility that has often been unrelated or disproportionate to the operating performance of particular companies. Broad market 
and industry factors, including potentially worsening economic conditions, inflation and other adverse effects or developments may negatively affect the 
market price of our common stock, regardless of our actual operating performance. As a result of this volatility, investors may not be able to sell their 
common stock at or above the price paid for the shares. The market price for our common stock may be influenced by many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated variations in our operating results; 

changes in financial estimates by us or by any securities analysts who might cover our stock; 

conditions or trends in our industry; 

changes in the structure of healthcare payment systems;

stock market price and volume fluctuations of comparable companies and, in particular, those that operate in the biopharmaceutical industry; 

announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures; 

announcements of investigations or regulatory scrutiny of our operations or lawsuits filed against us; 

capital commitments; 

investors’ general perception of us and our business; 

recruitment or departure of key personnel;  

sales of our common stock, including sales by our directors and officers or specific stockholders; and

general political and economic conditions. 

In addition, in the past, stockholders have initiated class action lawsuits against pharmaceutical and biotechnology companies following periods of 

volatility in the market prices of these companies’ stock. Such litigation, if instituted against us, could cause us to incur substantial costs and divert 
management’s attention and resources from our business. 

If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our 
stock price and trading volume could decline. 

The trading market for our common stock will be influenced by the research and reports that equity research analysts publish about us and our 

business. Equity research analysts may elect not to initiate or to continue to provide research coverage of our common stock, and such lack of research 
coverage may adversely affect the market price of our common stock. Even if we do have equity research analyst coverage, we will not have any control 
over the analysts or the content and opinions included in their reports. The price of our stock could decline if one or more equity research analysts 
downgrade our stock or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of our company or fails to 
publish reports on us regularly, demand for our stock could decrease, which in turn could cause our stock price or trading volume to decline.

The issuance of additional stock and other equity-linked securities in connection with financings, acquisitions, investments, our stock incentive plans 
or otherwise will dilute all other stockholders. 

Subject to compliance with applicable rules and regulations, we may issue our shares of common stock or securities convertible into our common 

stock from time to time in connection with a financing, acquisition, investment, our stock incentive plans or otherwise. For example, we, among other 
things, issued warrants to purchase 11,111,111 shares of common stock to certain investors in a registered direct offering. As of March 5, 2024, we had 
outstanding warrants to purchase an aggregate of 11,111,111 shares of common stock. The exercise of our outstanding warrants could result in significant 
dilution to existing stockholders, adversely affect 

55

Table of Contents

the market price of our common shares and impair our ability to raise capital through the sale of additional equity securities. Any such issuance could result 
in substantial dilution to our existing stockholders and cause the trading price of our common stock to decline. 

If we fail to meet all applicable requirements of Nasdaq and Nasdaq determines to delist our common stock, the delisting could adversely affect the 
market liquidity of our common stock and the market price of our common stock could decrease.

On September 27, 2023, we received a letter from Nasdaq, notifying us that, for the previous 30 consecutive business day periods prior to the date of 
the letter, the closing bid price for our common stock was below $1.00. In accordance with Nasdaq Listing Rule 5810(c)(3)(A) we were provided an initial 
period of 180 calendar days, or until March 25, 2024, to regain compliance with Nasdaq’s bid price requirement. On December 12, 2023, as a result of our 
common stock trading over $1.00 for 10 consecutive business days, we received a notice from the Nasdaq Listing Qualifications Office indicating that we 
regained compliance with the minimum bid price requirement under Nasdaq Listing Rule 5450(a)(1).

There can be no assurance that we will maintain compliance with the requirements for listing our common stock on Nasdaq. If we are unable to 

satisfy the Nasdaq criteria for continued listing, our common stock would be subject to delisting. A delisting of our common stock could negatively impact 
us by, among other things, reducing the liquidity and market price of our common stock; reducing the number of investors willing to hold or acquire our 
common stock, which could negatively impact our ability to raise equity financing; decreasing the amount of news and analyst coverage of us; and limiting 
our ability to issue additional securities or obtain additional financing in the future. In addition, delisting from Nasdaq may negatively impact our 
reputation and, consequently, our business.

If a significant number of our shares are sold into the market, it could cause the market price of our common stock to drop significantly, even if our 
business is doing well. 

Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell, or the market 

perceives that our stockholders intend to sell, substantial amounts of our common stock in the public market, the market price of our common stock could 
decline significantly. All of our outstanding shares of common stock are available for sale in the public market, subject only to the restrictions of Rule 144 
under the Securities Act in the case of our affiliates.

In addition, we have filed registration statements on Form S-8 registering the issuance of shares of common stock subject to options or other equity 

awards issued or reserved for future issuance under our equity incentive plans. These registered shares will be available for sale in the public market subject 
to vesting arrangements and exercise of options and, in the case of our affiliates, the restrictions of Rule 144. 

Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our 
management and hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower as a result. 

There are provisions in our certificate of incorporation and bylaws that may make it difficult for a third party to acquire, or attempt to acquire, 

control of our company, even if a change in control was considered favorable by you and other stockholders. For example, our board of directors has the 
authority to issue up to 10,000,000 shares of preferred stock. The board of directors can fix the price, rights, preferences, privileges, and restrictions of the 
preferred stock without any further vote or action by our stockholders. The issuance of shares of preferred stock may delay or prevent a change in control 
transaction. As a result, the market price of our common stock and the voting and other rights of our stockholders may be adversely affected. An issuance 
of shares of preferred stock may result in the loss of voting control to other stockholders. 

Our charter documents also contain other provisions that could have an anti-takeover effect, including:

•

•

•

•

•

only one of our three classes of directors are elected each year; 

stockholders are not entitled to remove directors other than by a 66 2⁄3% vote and only for cause; 

stockholders are not permitted to take actions by written consent; 

stockholders cannot call a special meeting of stockholders; and 

stockholders must give advance notice to nominate directors or submit proposals for consideration at stockholder meetings. 

In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which regulates corporate 

acquisitions by prohibiting Delaware corporations from engaging in specified business combinations with 

56

Table of Contents

particular stockholders of those companies. These provisions could discourage potential acquisition proposals and could delay or prevent a change in 
control transaction. They could also have the effect of discouraging others from making tender offers for our common stock, including transactions that 
may be in your best interests. These provisions may also prevent changes in our management or limit the price that investors are willing to pay for our 
stock. 

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for certain 
litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us 
or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for the 

following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any 
action asserting a claim for breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any action 
asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our 
amended and restated bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine. However, this exclusive forum provision would 
not apply to suits brought to enforce a duty or liability created by the Securities Act or the Exchange Act. The choice of forum provision may limit a 
stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may 
discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provision 
contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs 
associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

We are a “smaller reporting company” and as a result of the reduced disclosure and governance requirements applicable to smaller reporting 
companies, our common stock may be less attractive to investors. 

We are a “smaller reporting company,” meaning that the market value of our shares held by non-affiliates is less than $700 million and our annual 

revenue was less than $100 million during the most recently completed fiscal year. We will continue to be a smaller reporting company if either (i) the 
market value of our shares held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently 
completed fiscal year and the market value of our shares held by non-affiliates is less than $700 million. As a smaller reporting company, we may choose to 
present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and we have reduced disclosure 
obligations regarding executive compensation. In addition, as a smaller reporting company and non-accelerated filer, we are not required to comply with 
the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act.

We cannot predict whether investors will find our securities less attractive because we will rely on these exemptions. If some investors find our 
securities less attractive as a result of our reliance on these exemptions, the trading prices of our securities may be lower than they otherwise would be, 
there may be a less active trading market for our securities and the trading prices of our securities may be more volatile.

We have broad discretion in the use of our cash and cash equivalents and may invest or spend our cash in ways with which investors do not agree. 

We have broad discretion over the use of our cash and cash equivalents. Investors may not agree with our decisions, and our use of our cash may not 
yield any return on investment. Our failure to apply our resources effectively could compromise our ability to pursue our growth strategy. Investors will not 
have the opportunity to influence our decisions on how to use our cash and cash equivalents.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, will be the sole 
source of gains and investors may never receive a return on their investment. 

Investors should not rely on an investment in our common stock to provide dividend income. We have not declared or paid cash dividends on our 

common stock to date. We currently intend to retain our future earnings, if any, to fund the development and growth of our business. In addition, our prior 
loan agreement prohibited us from paying dividends without the consent of the lenders under the agreement, and we expect that the terms of any future debt
agreements would likewise preclude us from paying dividends. As a result, capital appreciation, if any, of our common stock will be investors’ sole source 
of gain for the foreseeable future. Investors seeking cash dividends should not purchase our common stock.

General Risk Factors

If our information technology systems or those third parties upon which we rely or our data, are or were compromised, we could experience adverse 
consequences resulting from such compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; 
disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse consequences.

In the ordinary course of our business, we and the third parties upon which we rely, process, collect, receive, store, process, generate, use, transfer, 

disclose, and share proprietary, confidential, and sensitive data, including personal data (such as health-related data), intellectual property, and trade secrets.

Our internal computer systems, and those of our CROs, contract manufacturing organizations and other third parties on whom we rely, are 

vulnerable to damage from computer viruses, unauthorized access, security breaches, natural disasters, terrorism, war and telecommunication and electrical 
failures. Cyberattacks, malicious internet-based activity, and online and offline fraud are prevalent and continue to increase. These threats are becoming 
increasingly difficult to detect and threaten the confidentiality, integrity, and availability of our sensitive information and information technology systems, 
and those of the third parties upon which we rely. These threats come from a variety of sources. In addition to traditional computer “hackers,” threat actors, 
personnel (such as through theft or misuse), sophisticated nation-states, and nation-state-supported actors now engage in attacks.  We and the third parties 
upon which we rely may be subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through phishing 
attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks 
(such as credential stuffing), personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or 
hardware failures, loss of data or other information technology assets, adware, telecommunications failures, earthquakes, fires, floods, and other similar 
threats. 

If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may 
experience adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); 
additional reporting requirements and/or oversight; restrictions on processing sensitive information (including personal data); litigation (including class 
claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; diversion of management attention; interruptions in 
our operations (including availability of data); financial loss; and other similar harms.  

Remote work has become more common and has increased risks to our information technology systems and data, as more of our employees utilize 

network connections, computers and devices outside our premises or network, including working at home, while in transit and in public locations.

Future or past business transactions (such as acquisitions or integrations) could expose us to additional cybersecurity risks and vulnerabilities, as our 
systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies.  Furthermore, we may discover 
security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our 
information technology environment and security program.

We rely on third-party service providers and technologies to operate critical business systems to process sensitive information in a variety of 
contexts, including, without limitation, cloud-based infrastructure, data center facilities, encryption and authentication technology, employee email, content 
delivery to customers, and other functions. Our ability to monitor these third parties’ information security practices is limited, and these third parties may 
not have adequate information security measures in place.  If our third-party service providers experience a security incident or other interruption, we could 
experience adverse consequences.  While we may be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related 
obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award.

In addition, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply 
chain or our third-party partners’ supply chains have not been compromised. While we have implemented security measures designed to protect against 
security incidents, there can be no assurance that these measures will be effective.

Any of the foregoing could result in a material disruption of our clinical and product development activities and business operations, in addition to 
possibly requiring substantial expenditures of resources to remedy. For example, the loss or compromise of clinical trial data from completed or ongoing 
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 incident was to result in a loss or damage to our data or applications, or inappropriate disclosure of confidential or proprietary 
information, or any personal data for which we are responsible, we could incur significant unexpected losses, expenses and liabilities, we could face 
litigation or suffer reputational harm and the further development of our product candidates could be delayed. Our contracts may not contain limitations 

58

Table of Contents

of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, 
damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to 
protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially 
reasonable terms or at all, or that such coverage will pay future claims.

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

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the 
handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous materials, including 
chemicals and biological materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these 
materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from 
our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur 
significant costs associated with civil or criminal fines and penalties for failure to comply with such 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 resulting 

from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for 
environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These 
current or future laws and regulations may impair our research, development or production efforts. Our failure to comply with these laws and regulations 
also may result in substantial fines, penalties or other sanctions. 

The 2017 comprehensive tax reform bill, as modified by the CARES Act, the Inflation Reduction Act, and possible future changes in tax laws or 
regulations could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law the Tax Act, which significantly revised the Internal Revenue Code of 1986, as amended, 

or the Code. In March 2020, the Tax Act was modified in certain respects by the Coronavirus Aid, Relief, and Economic Security (CARES) Act. More 
recently, the Inflation Reduction Inflation of 2022, or the IRA, was enacted which includes provisions that impact the U.S. federal income taxation of 
corporations, including imposing a minimum tax on the book income of certain large corporations and an excise tax on certain corporate stock repurchases 
that would be imposed on the corporation repurchasing such stock. Future guidance from the U.S. Internal Revenue Service and other tax authorities with 
respect to the Tax Act, as modified by the CARES Act, and the IRA, may affect us, and certain aspects of the Tax Act, CARES Act and IRA could be 
repealed or modified in future legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to our U.S. operations, the 
taxation of foreign earnings, and the deductibility of expenses under the Tax Act, the CARES Act, the IRA, or future tax reform legislation could have a 
material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase 
our future U.S. tax expense. The foregoing items, as well as any other future changes in tax laws, could have a material adverse effect on our business, cash 
flow, financial condition, or results of operations. In addition, it is uncertain if and to what extent various states will conform to the Tax Act, the CARES 
Act, the IRA, or any newly enacted federal tax legislation.

Our effective tax rate may fluctuate, and we may incur obligations in tax jurisdictions in excess of accrued amounts.

We are subject to taxation in numerous U.S. states and territories. As a result, our effective tax rate is derived from a combination of applicable tax 

rates in the various places in which we operate. In preparing our financial statements, we estimate the amount of tax that will become payable in each of 
such places. Nevertheless, our effective tax rate may be different than experienced in the past due to numerous factors, including changes in the mix of our 
profitability from state to state, the results of examinations and audits of our tax filings, our inability to secure or sustain acceptable agreements with tax 
authorities, changes in accounting for income taxes and changes in tax laws. Any of these factors could cause us to experience an effective tax rate 
significantly different from previous periods or our current expectations and may result in tax obligations in excess of amounts accrued in our financial 
statements.

We plan to use potential future operating losses and our federal and state NOL carryforwards to offset future taxable income, if any. However, our 
ability to use existing NOL carryforwards could be limited as a result of issuances of equity securities. 

As of December 31, 2023, we had approximately $225.9 million of federal and $89.3 million of state net operating loss, or NOL, carryforwards. If 

not utilized, the portion of these federal NOL carryforwards arising in tax years beginning before 2018 will 

59

Table of Contents

begin to expire at various dates beginning in 2034, and these state NOL carryforwards will begin to expire at various dates beginning in 2027. Under the 
Tax Act, as modified by the CARES Act, federal NOLs incurred in taxable years beginning in 2018 and in later years may be carried forward indefinitely, 
but the deductibility of such federal NOLs is limited for taxable years beginning after 2020 to 80% of taxable income. Certain states have conformed to the 
federal NOL rules included in the Tax Act and CARES Act. However, under Section 382 of the Code of 1986, as interpreted by the U.S. Internal Revenue 
Service, the amount of benefits from our NOL carryforwards may be impaired or limited if we incur ownership changes. The completion of our IPO, 
follow-on public offerings, private placements and other transactions that have occurred, and future offerings of our securities have triggered, and may in 
the future trigger additional, ownership changes. We have determined that three such ownership changes have occurred in the past. We have determined 
that $38,000 and $2,000 of our deferred tax assets related to federal NOL and R&D credits, respectively, will expire due to Section 382.

In addition, since we will need to raise substantial additional funding to finance our operations, we may undergo ownership changes in the future. 

Any such additional limitations may significantly reduce the value of our NOL carryforwards before they expire, which could result in greater tax liabilities 
than we would incur in the absence of such limitations. At the state level, there may be periods during which the use of net operating loss carryforwards is 
suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired. 

We are subject to the reporting requirements of the Securities Exchange Act of 1934, the Sarbanes-Oxley Act and the rules and regulations of The 

Nasdaq Stock Market. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal 
control over financial reporting. Because we are a smaller reporting company and a non-accelerated filer, we are not required to comply with the auditor 
attestation requirements of Section 404 of the Sarbanes-Oxley Act. However, we must perform system and process evaluation and testing of our internal 
control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting in this report and future 
annual reports on Form 10-K, as required by Section 404 of the Sarbanes-Oxley Act. This requires that we incur substantial additional professional fees and 
internal costs to expand our accounting and finance functions and that we expend significant management efforts. 

We may discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement 
of our financial statements. Our internal control over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how 
well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent 
limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all 
control issues and instances of fraud will be detected. 

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if we are unable to maintain 

proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If that were to happen, the market price of 
our stock could decline and we could be subject to sanctions or investigations by The Nasdaq Stock Market, the Securities and Exchange Commission or 
other regulatory authorities. 

We incur significant costs and demands upon management as a result of being a public company. 

As a public company listed in the United States, we incur significant legal, accounting and other costs, which we expect to increase if we cease to be 

a smaller reporting company under SEC rules. These additional costs could negatively affect our financial results. In addition, changing laws, regulations 
and standards relating to corporate governance and public disclosure, including regulations implemented by the SEC and The Nasdaq Stock Market, may 
increase legal and financial compliance costs and make some activities more time consuming. These laws, regulations and standards are subject to varying 
interpretations and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. We 
intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative 
expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. 

If, notwithstanding our efforts to comply with new laws, regulations and standards, we fail to comply, regulatory authorities may initiate legal 
proceedings against us and our business may be harmed. Failure to comply with these rules might also make it more difficult for us to obtain some types of 
insurance, including director and officer liability insurance, and we might be forced to accept reduced policy limits and coverage or incur substantially 
higher costs to obtain the same or similar coverage. The impact of these events could also make it more difficult for us to attract and retain qualified 
persons to serve on our board of directors, on committees of our board of directors or as members of senior management.

Climate change, extreme weather events, earthquakes and other natural disasters could adversely affect our business.

In recent years, extreme weather events and changing weather patterns such as storms, flooding, droughts, fires and temperature changes have 

become more common. As a result, we are potentially exposed to varying natural disaster or extreme weather risks such as hurricanes, tornadoes, fires, 
droughts or floods, or other events that may result from the impact of climate change on the environment, such as sea level rise. The potential impacts of 
climate change may also include increased operating costs associated with additional regulatory requirements and investments in reducing energy, water 
use and greenhouse gas emissions.

Adverse global economic conditions and geopolitical tensions could have a negative effect on our business, results of operations and financial 
condition and liquidity.

In recent years, concerns about the global economic outlook have adversely affected market and business conditions in general. Macroeconomic 

weakness and uncertainty could make it more difficult for us or the licensing partners on whom we depend to commercialize XIPERE to manage our 
respective operations. Geopolitical tensions, such as Russia’s recent incursion into Ukraine, ongoing conflicts between the United States and China, tariff 
and trade policy changes, economic sanctions and increasing potential of conflict involving countries in Asia, including countries that are part of the Arctic 
Territory under our license agreement with Arctic Vision, create uncertainty for us and for global commerce generally. Sustained or worsening of global 
economic conditions and increasing geopolitical tensions may increase our cost of doing business, limit our ability to access capital, disrupt our supply 
chain operations or the supply chain operations of our licensing partners and intensify pricing pressures. Any or all of these factors could negatively affect 
our business, financial condition and result of operations.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Risk management and strategy

We have implemented and maintain various information security processes designed to identify, assess and manage material risks from 

cybersecurity threats to our critical computer networks, third party hosted services, communications systems, hardware and software, and our critical data, 
including intellectual property, confidential information that is proprietary, strategic or competitive in nature, and trade secrets, data we may collect about 
trial participants in connection with clinical trials, sensitive third-party data, business plans, transactions, and financial information, or collectively 
Information Systems and Data.  

Our cybersecurity function, which comprises, in part, our information technology team, helps identify, assess and manage our cybersecurity threats 

and risks. Our cybersecurity function identifies and assesses risks from cybersecurity threats by monitoring and evaluating our threat environment using 
various methods including, for example, manual tools, internal or external audits, automated tools, subscribing to and analyzing reports and services that 
identify cybersecurity threats and threat actors, conducting threat assessments for internal and external threats, conducting scans of the threat environment, 
evaluating our (and our industry’s) risk profile, using external intelligence feeds, conducting vulnerability assessments to identify vulnerabilities, and 
evaluating threats reported to us.  Depending on the environment, we implement and maintain various technical, physical, and organizational measures and 
processes designed to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data, including, for example: incident 
detection and response, an incident response plan, a vendor risk management program, employee training, data encryption, access controls, physical 
security, network security controls, systems monitoring, cyber insurance, and asset management, tracking, and disposal. 

Our assessment and management of material risks from cybersecurity threats are integrated into the Company’s overall risk management processes. 

For example, the cybersecurity function works with management to prioritize our risk management processes and mitigate cybersecurity threats that are 
more likely to lead to a material impact to our business.

We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, 
including for example professional services firms (including legal counsel), threat intel service providers, and cybersecurity software providers. We also 
use third-party service providers to perform a variety of functions throughout our business, such as hosting companies, application providers, contract 
research organizations, supply chain resources, and contract manufacturing organizations. We manage cybersecurity risks associated with our use of these 
providers by conducting audits and risk assessments on certain vendors, requesting and analyzing responses on a security questionnaire, and reviewing 
relevant reports. 

61

Table of Contents

For a description of the risks from cybersecurity threats that may materially affect the Company and how they may do so, see our risk factors under 
Part 1. Item 1A. Risk Factors in this Annual Report on Form 10-K, including “—If our information technology systems or those third parties upon which 
we rely or our data, are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to 
regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and 
other adverse consequences.”.

Governance 

Our board of directors addresses the Company’s cybersecurity risk management as part of its general oversight function. The audit committee is 

responsible for overseeing Company’s cybersecurity risk management processes, including oversight and mitigation of risks from cybersecurity threats.  

Our cybersecurity risk assessment and management processes are implemented and maintained by certain members of management, including our 
Senior Director of Information Technology, who has over 23-years of experience in IT management (including cybersecurity) and a degree in Computer 
Information Systems.

Our Senior Director of IT, as part of our overall cybersecurity function, is responsible for hiring appropriate personnel, helping to integrate 
cybersecurity risk considerations into the Company’s overall risk management strategy, and communicating key priorities to relevant personnel. Our Chief 
Financial Officer, or CFO, is responsible for approving budgets, helping prepare for cybersecurity incidents, approving cybersecurity processes, and 
reviewing security assessments and other significant security-related incidents. 

Our response process to cybersecurity incidents is designed to escalate certain incidents to members of management depending on the 

circumstances, including the CFO. Our CFO and Senior Director of IT work with the Company’s incident response team to help the Company mitigate and 
remediate cybersecurity incidents of which they are notified.  In addition, the Company’s incident response policy includes reporting to the board of 
directors committee responsible for certain cybersecurity incidents.

The audit committee receives an annual update from our cybersecurity function concerning the Company’s significant cybersecurity threats and risk 

and the processes the Company has implemented to address them. In addition, they receive timely notifications of significant cybersecurity incidences 
based on our cybersecurity response plan. The audit committee also has access to various reports, summaries or presentations related to cybersecurity 
threats, risk and mitigation.

ITEM 2. PROPERTIES

Our principal offices occupy approximately 14,000 square feet of office space in Alpharetta, Georgia under a lease with an initial term until 

November 2026, with a renewal option for one additional three-year term. 

We believe that our current leased facilities are suitable and adequate to meet our current needs. We intend to add new facilities or expand existing 
facilities as we add employees, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion 
of our operations.

ITEM 3. LEGAL PROCEEDINGS

We are not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceeding against us that we 

believe could have a material adverse effect on our business, operating results or financial condition.

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 in conjunction with the financial 

statements and the related notes to those statements included later in this Annual Report. In addition to historical financial information, the following 
discussion contains forward‑looking statements that reflect our plans, estimates, beliefs and expectations that involve risks and uncertainties. Our actual 
results and the timing of events could differ materially from those discussed in these forward‑looking statements. Factors that could cause or contribute to 
these differences include those discussed below and elsewhere in this Annual Report, particularly in Item 1A. “Risk Factors” and “Special Note Regarding 
Forward‑Looking Statements.” 

Overview

We are a biopharmaceutical company focused on revolutionizing the delivery of therapies to the back of the eye through the suprachoroidal space, or 

SCS. Our SCS injection platform, utilizing our proprietary SCS Microinjector, enables an in-office, repeatable, non-surgical procedure for the targeted and 
compartmentalized delivery of a wide variety of therapies to the macula, retina or choroid to potentially preserve and improve vision in patients with sight-
threatening eye diseases. Our suprachoroidal injection technology can be used in conjunction with existing drugs designed for delivery to the SCS, novel 
therapies, and future therapeutic innovations. We believe our proprietary suprachoroidal administration platform has the potential to become a standard for 
delivery of therapies intended to treat chorioretinal diseases.

We are leveraging our SCS injection platform by building an internal research and development pipeline targeting retinal diseases and by creating 
external collaborations with other companies. We are developing our own pipeline of small molecule product candidates for administration via our SCS 
Microinjector, and we also strategically partner with companies developing other ophthalmic therapeutic innovations to be administered using our SCS 
injection platform. Our first product, XIPERE (triamcinolone acetonide injectable suspension) for suprachoroidal use, was approved by the U.S. Food and 
Drug Administration, or the FDA, in October 2021. Approval of XIPERE was a significant milestone for us as it is the first approved therapeutic delivered 
into the SCS, the first commercial product developed by us, and the first therapy for macular edema associated with uveitis.

Our operations to date have been limited to organizing and staffing our company, raising capital, conducting preclinical studies and clinical trials 
and undertaking other research and development initiatives. To date, we have only generated revenue through upfront payments and milestone payments 
related to license agreements and other revenue generated from collaboration agreements. We have primarily financed our operations through public 
offerings and private placements of our equity securities, issuances of convertible promissory notes and loan agreements. As of December 31, 2023, we had 
an accumulated deficit of $320.9 million. We recorded net losses of $32.5 million and $32.9 million for the years ended December 31, 2023 and 2022, 
respectively, and net income of $0.4 million for the year ended December 31, 2021. We anticipate that a substantial portion of our capital resources and 
efforts in the foreseeable future will be focused on completing the necessary development for and obtaining regulatory approval of our product candidates, 
as well as discovering compounds and developing proprietary therapeutics to utilize with our SCS Microinjector.

We expect to continue to incur significant and increasing operating losses at least for the next several years. We do not expect to generate significant 

product or license and other revenue unless and until XIPERE is successfully commercialized by its licensees or until we successfully complete 
development of, obtain regulatory approval for and commercialize additional product candidates, either on our own or together with a third party. Our 
financial results may fluctuate significantly from quarter to quarter and year to year, depending on the timing of our clinical trials and our expenditures on 
other research and development activities. We expect clinical trial expenses to increase in 2024 as a result of our ongoing Phase 2b clinical trial of CLS-AX 
as well as continuing our pipeline development. We also will continue our efforts to seek to discover, research and develop additional product candidates 
and seek regulatory approvals in additional regions for XIPERE for the treatment of macular edema associated with uveitis. Based on our current research 
and development plans, we expect to have sufficient resources to fund our planned operations into the third quarter of 2025. We will require additional 
capital in order to complete clinical development of CLS-AX.

Macroeconomic Considerations

Unfavorable conditions in the economy in the United States and abroad may negatively affect the growth of our business and our results of 
operations. For example, macroeconomic events, rising inflation, the U.S. Federal Reserve raising interest rates, and conflicts in Ukraine, Russia and the 
Middle East have led to economic uncertainty globally. The effect of macroeconomic conditions may not be fully reflected in our results of operations until 
future periods. If, however, economic uncertainty increases or the global economy worsens, our business, financial condition and results of operations may 
be harmed. For further discussion of the potential impacts of macroeconomic events on our business, financial condition, and operating results, see the 
section titled “Risk Factors.”

64

Table of Contents

Components of Operating Results

Revenue

We have not generated any revenue from the sale of XIPERE and we do not expect to generate any other product revenue unless or until we obtain 

regulatory approval of and commercialize our other product candidates, either on our own or with a third party. The revenue received under the Bausch 
license agreement, as well as other certain payments from our licensees, will be recorded as non-cash revenue until we have fulfilled our obligations under 
the Purchase and Sale Agreement. Our revenue in recent years has been generated primarily from our license agreements. We continue to seek to enter into 
additional license and other agreements with third parties to evaluate the potential use of our proprietary SCS Microinjector with the third party’s product 
candidates for the treatment of various eye diseases. These agreements may include payments to us for technology access, upfront license payments, 
regulatory and commercial milestone payments and royalties.

Research and Development

Since our inception, we have focused on our development programs. Research and development expenses consist primarily of costs incurred for the 

research and development of our preclinical and clinical product candidates, which include:

•

•

•

•

•

•

•

•

employee-related expenses, including salaries, benefits, travel and share-based compensation expense for research and development 
personnel;

expenses incurred under agreements with contract research organizations, or CROs, as well as contract manufacturing organizations and 
consultants that conduct clinical trials and preclinical studies;

costs associated with preclinical activities and clinical trials;

costs associated with submitting regulatory approval applications for our product candidates;

costs associated with training physicians on the suprachoroidal injection procedure and educating and providing them with appropriate 
product candidate information;

costs associated with technology and intellectual property licenses;

costs for our research and development facility; and

depreciation expense for assets used in research and development activities.

We expense research and development costs to operations as incurred. These costs include preclinical activities, such as manufacturing and stability 

and toxicology studies, that are supportive of a product candidate itself. In addition, there are expenses related to clinical trials and similar activities for 
each program, including costs associated with CROs. Clinical costs are recognized based on the terms of underlying agreements, as well as an evaluation of 
the progress to completion of specific tasks using data such as patient enrollment, clinical site activations and additional information provided to us by our 
vendors about their actual costs occurred. Expenses related to activities that support more than one development program or activity, such as salaries, share-
based compensation and depreciation, are not classified as direct preclinical costs or clinical costs and are separately classified as unallocated.

The following table shows our research and development expenses by type of activity for the years ended December 31, 2023, 2022 and 2021.

Our expenses related to clinical trials are based on estimates of patient enrollment and related expenses at clinical investigator sites as well as 
estimates for the services received and efforts expended under contracts with research institutions, consultants and CROs that conduct and manage clinical 
trials on our behalf. We generally accrue expenses related to clinical trials based on contracted amounts applied to the level of patient enrollment and 
activity according to the protocol. If future timelines or contracts are modified

Table of Contents

based upon changes in the clinical trial protocol or scope of work to be performed, we would modify our estimates of accrued expenses accordingly on a 
prospective basis. 

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have 

higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. 
However, it is difficult to determine with certainty the duration and completion costs of our current or future preclinical programs and clinical trials of our 
product candidates, or if, when or to what extent we will generate revenues from the commercialization and sale of any of our product candidates that 
obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates.

The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors that include the 

following:

•

•

•

•

•

•

•

•

•

•

•

•

the costs associated with process development, scale-up and manufacturing of our product candidates including the SCS Microinjector for 
clinical trials and for requirements associated with regulatory filings;

the number of trials required for approval and any requirement for extension trials;

per patient trial costs;

the number of patients that participate in the trials;

the number of sites included in the trials;

the countries in which the trials are conducted;

the length of time required to enroll eligible patients;

the number of doses that patients receive;

the drop-out or discontinuation rates of patients;

potential additional safety monitoring or other studies requested by regulatory agencies;

the duration of patient follow-up; and

the efficacy and safety profiles of the product candidates.

In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability 

and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical 
success of each product candidate, as well as an assessment of each product candidate’s commercial potential.

General and Administrative

General and administrative expenses consist primarily of salaries and other related costs, including share-based compensation, for personnel in 

executive, finance and administrative functions. General and administrative costs historically included commercial pre-launch preparations for XIPERE, 
and also include facility related costs not otherwise included in research and development expenses, as well as professional fees for legal, patent, 
consulting, and accounting and audit services.

Other Income 

Other income consists of the gain on the extinguishment of the Paycheck Protection Program, or PPP, Loan and accrued interest and interest income 

earned on our cash and cash equivalents. Interest income is not currently significant to our financial statements.

66

Table of Contents

Non-cash Interest Expense on Liability Related to the Sales of Future Royalties

Non-cash interest expense on liability related to the sales of future royalties consists of imputed interest on the carrying value of the liability and the 

amortization of the related issuance costs.

Critical Accounting Policies and Significant Judgments and Estimates 

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, 

which have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of 
these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, 
disclosure of contingent assets and liabilities as of the dates of the balance sheets and the reported amounts of expenses during the reporting periods. In 
accordance with U.S. GAAP, we evaluate our estimates and judgments on an ongoing basis. Significant estimates include assumptions used in royalty 
financing obligation, the determination of share-based compensation and some of our research and development expenses. We base our estimates on 
historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates 
under different assumptions or conditions.

We define our critical accounting policies, in accordance with U.S. GAAP, as those that require us to make subjective estimates and judgments about 

matters that are uncertain and are likely to have a material impact on our financial condition and results of operations, as well as the specific manner in 
which we apply those principles. While our significant accounting policies are more fully described in Note 2 to our financial statements appearing 
elsewhere in this Annual Report, we believe the following are the critical accounting policies used in the preparation of our financial statements that require 
significant estimates and judgments. 

Revenue recognition

We recognize revenue from our contracts with customers under Financial Accounting Standards Board, or FASB, Accounting Standards 

Codification, or ASC, Topic 606, Revenue from Contracts with Customers, or ASC 606. Under ASC 606, we recognize revenue in an amount that reflects 
the consideration to which we expect to be entitled in exchange for the transfer of promised goods or services to customers. To determine revenue 
recognition for contracts with customers that are within the scope of ASC 606, we perform the following steps: (1) identify the contract with the customer, 
(2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations 
in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. We only apply the five-step model to contracts when it 
is probable that we will collect the consideration we are entitled to in exchange for the goods or services transferred to the customer.

As part of the accounting for our revenue arrangements, we develop assumptions that require judgment such as the estimate of the stand-alone 

selling price for each performance obligation identified in the contract. 

Licenses of intellectual property:  If the license to our intellectual property is determined to be distinct from the other performance obligations 
identified in the arrangement, we recognize revenue allocated to the license when the license is transferred to the customer and the customer is able to use 
and benefit from the license. For licenses that are bundled with other promised goods or services, we utilize judgment to assess the nature of the combined 
performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the 
appropriate method of measuring progress for purposes of recognizing revenue. We evaluate the measure of progress each reporting period and, if 
necessary, adjust the measure of performance and related revenue recognition.

Milestone Payments: At the inception of each arrangement that includes development, commercialization, and regulatory milestone payments, we 
evaluate whether the achievement of the milestones is considered probable and estimate the amount to be included in the transaction price using the most 
likely amount method. Performance milestone payments represent a form of variable consideration. If it is probable that a significant revenue reversal 
would not occur, the associated milestone value is included in the transaction price. Achievement of milestones that are not within our or our licensee’s 
control, such as regulatory approvals, are not considered probable until the approvals are achieved. The transaction price is then allocated to each 
performance obligation on a relative stand-alone selling price basis and we recognize revenue as or when the performance obligations under the contract 
are satisfied. At the end of each subsequent reporting period, we re-evaluate the probability of achieving such milestones and any related constraint, and if 
necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect 
revenues and earnings in the period of adjustment.

Manufacturing Supply Services:  Arrangements that include a promise for future supply of drug substance or drug product for either clinical 
development or commercial supply at the customer’s discretion are generally considered options. The arrangements may also include assistance and 
oversight of the customer’s use of the drug substance or drug product. We assess if these options provide a material right to the licensee and if so, they are 
accounted for as separate performance obligations at the outset of the arrangement. 

Royalties:  For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed 
to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur or (ii) when the performance 
obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have not received any royalty 
revenue resulting from any of our licensing arrangements.

Accrued expenses 

As part of the process of preparing our consolidated financial statements, we are required to estimate accrued expenses. This process involves 
reviewing open contracts and purchase orders, communicating with applicable vendor personnel to identify services that have been performed on our 
behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise 
notified of actual cost. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and 
circumstances known to us. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples 
of estimated accrued expenses include fees paid to CROs and investigative sites in connection with clinical trials. 

We accrue our expenses related to clinical trials based on our estimates of the services received and efforts expended pursuant to contracts with 
multiple research institutions and CROs that conduct research activities or manage clinical trials on our behalf. The financial terms of these agreements are 
subject to negotiation, vary from contract to contract and may result in uneven payment flows. Payments under some of these contracts depend on factors 
such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over 
which services will be performed and the level of effort to be expended in each period. If the level of effort varies from our estimate, we will adjust the 
accrual accordingly. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from 
our estimates. Although we do not currently anticipate the future settlement of existing accruals to differ materially from our estimates, our understanding 
of the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in us reporting 
amounts that are too high or too low for any period. 

Share-based compensation 

Compensation cost related to share-based awards granted to employees, directors and consultants is measured based on the estimated fair value of 
the award at the grant date. We estimate the fair value of stock options using a Black-Scholes option pricing model. Share-based compensation costs are 
expensed on a straight-line basis over the relevant vesting period. The fair value of restricted stock units, or RSUs, granted is measured based on the market 
value of our common stock on the date of grant and is recognized ratably over the requisite service period, which is generally the vesting period of the 
awards. All share-based compensation costs are recorded in general and administrative or research and development costs in the statements of operations 
based upon the underlying employees’ roles.

Significant factors, assumptions and methodologies used in determining fair value 

Determining the appropriate fair value measurement of share-based awards requires the use of subjective assumptions. The determination of the fair 
value measurement of options using the Black-Scholes option pricing model is affected by our estimated common stock fair values as well as assumptions 
regarding a number of other subjective variables. These other variables include the expected term of the options, our expected stock price volatility over the 
expected term of the options, stock option exercise and cancellation behaviors, risk-free interest rates and expected dividends. 

We estimate the fair value of stock options at the grant date using Black-Scholes option pricing model with the following assumptions: 

•

•

•

Fair value of our common stock. We estimate the fair value of our common stock by reference to the closing price of our common stock on 
The Nasdaq Global Market on the date of grant.

Volatility. We calculate expected volatility based on the historical volatility of our common stock.

Expected term. In the years ended December 31, 2023 and 2022, we used historical data to calculate the expected term. In the year ended 
December 31, 2021, we used the simplified method as prescribed by the SEC Staff Accounting Bulletin 

68

Table of Contents

No. 107, Share-Based Payment, as we did not have sufficient historical exercise and post-vesting termination data to provide a reasonable 
basis upon which to estimate the expected term of stock options granted to employees.

Risk-free rate. The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected time to 
liquidity.

Forfeitures. Forfeitures are accounted for as they occur.

Dividend yield. We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the foreseeable future.

•

•

•

We have an employee stock purchase plan that is considered a compensatory plan. The fair value of the discount and the look-back period of the 

employee stock purchase plan are estimated using the Black-Scholes option pricing model and expense is recognized over the six-month withholding 
period prior to the purchase date.

Share-based compensation expense related to stock options, the employee stock purchase plan and RSUs aggregated $4.2 million, $4.9 million and 

$5.1 million for the years ended December 31, 2023, 2022 and 2021, respectively. 

Liabilities Related to the Sales of Royalties and Non-Cash Interest Expense

In connection with the Purchase and Sale Agreement, we recognized a liability related to the sales of future royalties under ASC 470-10 Debt and 

ASC 835-30 Interest - Imputation of Interest. The initial funds received by us pursuant to the terms of the Purchase and Sale Agreement were recorded as a 
liability and are accreted under the effective interest method up to the estimated amount of future royalties and milestone payments to be made under the 
Purchase and Sale Agreement. The issuance costs were recorded as a direct deduction to the carrying amount of the liability and are being amortized under 
the effective interest method over the estimated period the liability will be repaid. We estimate the total amount of future royalty revenue and milestone 
payments to be generated over the life of the Purchase and Sale Agreement, and a significant increase or decrease in these estimates could materially 
impact the liability balance and the related interest expense. If the timing of the receipt of royalty payments or milestones is materially different from the 
original estimates, we will prospectively adjust the effective interest and the related amortization of the liability and related issuance costs.

Tax valuation allowance  

We recorded aggregate deferred tax assets of $47.4 million, primarily related to our net operating losses, as of December 31, 2023, which have been 
fully offset by a valuation allowance due to uncertainties surrounding our ability to realize these tax benefits. We record a valuation allowance if it is more 
likely than not that a deferred tax asset will not be realized. We provided a full valuation allowance on our deferred tax assets that primarily consist of 
cumulative net operating losses, or NOLs, for the period from our inception through December 31, 2023. We incurred a net loss for tax purposes of $7.8 
million for the year ended December 31, 2023. Due to our three-year cumulative loss position, history of operating losses and losses expected to be 
incurred in the foreseeable future, we considered it necessary to provide for a full valuation allowance against our net deferred tax assets. 

Our deferred tax assets are primarily composed of federal and state tax NOL carryforwards. As of December 31, 2023, we had federal NOL 
carryforwards of $225.9 million and state NOL carryforwards of $89.3 million available to reduce future taxable income, if any. These federal NOL 
carryforwards will begin to expire at various dates starting in 2034. The state NOL carryforwards will begin to expire at various dates starting in 2027. In 
general, if we experience a greater than 50 percentage point aggregate change in ownership of specified significant stockholders over a three-year period, 
utilization of our pre-change NOL carryforwards will be subject to an annual limitation under Section 382 of the U.S. Internal Revenue Code of 1986, as 
amended, or the Code, and similar state laws. Such limitations may result in expiration of a portion of the NOL carryforwards before utilization and may be 
substantial. The completion of our IPO, follow-on public offerings, private placements and other transactions that have occurred, and future offerings of our 
securities have triggered, and may in the future trigger additional, ownership changes. We have determined that three such ownership changes have 
occurred in the past.  We have determined that $38,000 and $2,000 of our deferred tax assets related to federal NOL and R&D credits, respectively, will 
expire due to Section 382. In addition, if we experience a Section 382 ownership change as a result of future offerings or changes in our stock ownership, 
some of which changes are outside our control, the tax benefits related to the NOL carryforwards may be further limited or lost.

Revenue. In the year ended December 31, 2023 and 2022, we recognized $8.2 million and $1.3 million of revenue associated with our license 

agreements. License revenue for the year ended December 31, 2023 was primarily a result of the upfront license fee payment of $5.0 million from 
BioCryst, $1.4 million of milestone payments from Aura and $1.0 million from providing training materials and clinical trial products to our licensees. 
License revenue for the year ended December 31, 2022 was primarily from providing training materials and clinical trial products to our licensees. 

Cost of Goods Sold. In the years ended December 31, 2023 and 2022, we recognized $0.4 million and $0.2 million, respectively, in cost of goods 

sold related to the sales of our SCS Microinjector kits to our licensees.

Research and development. Research and development expense increased by $1.2 million, from $19.6 million for the year ended December 31, 2022 

to $20.8 million for the year ended December 31, 2023. This increase was primarily due to a $6.8 million increase for  the costs of ODYSSEY, a Phase 2b 
clinical trial of CLS-AX and related manufacturing costs for formulation and production. This was offset by a $2.2 million decrease in costs for OASIS, a 
Phase 1/2a clinical trial of CLS-AX and the OASIS extension study. Additionally, there was $1.4 million decrease in costs related to our other programs, a 
$0.2 million decrease in costs related to XIPERE, a $0.7 million decrease in employee related costs and $0.8 million in research and development tax 
credits received in the current year.

General and administrative. General and administrative expenses increased by $0.1 million for the years ended December 31, 2023 and 2022. This 

increase was primarily a result of a $0.7 million increase in professional fees, partially offset by a $0.2 million decrease in patent related expenses and a 
$0.3 million decrease for insurance costs.

Other income.  Other income for the year ended December 31, 2023 and 2022 was primarily comprised of interest income from the cash and cash 

equivalents. The increase for the year ended December 31, 2023 was due to higher interest rates.

Non-cash interest expense from liability related to the sales of future royalties. Non-cash interest expense for the year ended December 31, 2023 and 

2022 was comprised of imputed interest on the liability related to the sales of future royalties and the amortization of the associated issuance costs. The 
increase was due to a full year of interest expense for the year ended December 31, 2023 versus five months of interest expense for the year ended 
December 31, 2022.

Revenue. In the year ended December 31, 2022 and 2021, we recognized $1.3 million and $29.6 million of revenue associated with our license 
agreements. License revenue for the year ended December 31, 2022 was primarily from providing training materials and clinical trial products to our 
licensees. License revenue for the year ended December 31, 2021 was primarily a result of (i) the  milestone payments from Bausch that consisted of $5.0 
million received upon FDA approval of XIPERE, the recognition of $5.0 million of deferred revenue for the upfront milestone payment and the recognition 
of a $10.0 million milestone for pre-launch activities and (ii) an aggregate of $8.0 million received from Arctic Vision for FDA approval of XIPERE, 
territory expansion and certain development milestones. 

Cost of Goods Sold. In the year ended December 31, 2022, we recognized $0.2 million in cost of goods sold related to the sales of our SCS 

Microinjector kits to our licensees.

Research and development. Research and development expense increased by $1.1 million, from $18.5 million for the year ended December 31, 2021 

to $19.6 million for the year ended December 31, 2022. This increase was primarily due to a $0.9 million increase in costs for the CLS-AX program, 
including costs for OASIS, a Phase 1/2a clinical trial of CLS-AX, the OASIS extension study and the preliminary startup costs of ODYSSEY, a Phase 2b 
clinical trial of CLS-AX. Additionally, there was a $1.2 million increase in costs related to our other programs and a $0.7 million increase in costs related to 
an increase in headcount. This is partially offset by a $2.3 million decrease in costs related to XIPERE.

General and administrative. General and administrative expenses increased by $0.1 million for the years ended December 31, 2022 and 2021. This 

increase was primarily a result of a $0.4 million increase in patent related expenses and a $0.5 million decrease in costs related to employee benefits.

Other income.  Other income for the year ended December 31, 2022 was primarily comprised of interest income from the cash and cash equivalents. 

Other income for the year ended December 31, 2021 was primarily comprised of the gain on the extinguishment of debt from the forgiveness of the PPP 
Loan and accrued interest.

Non-cash interest expense from liability related to the sales of future royalties. Non-cash interest expense for the year ended December 31, 2022 was 

comprised of imputed interest on the liability related to the sales of future royalties and the amortization of the associated issuance costs.

Liquidity and Capital Resources

Sources of Liquidity

We have funded our operations primarily through the proceeds from public offerings of our common stock, sales of convertible preferred stock and 

the issuance of long-term debt. As of December 31, 2023, we had cash and cash equivalents of $28.9 million. We

invest any cash in excess of our immediate requirements primarily with a view to liquidity and capital preservation. As of December 31, 2023, our funds 
were held in cash and money market funds. 

On February 6, 2024, we entered into a securities purchase agreement with institutional investors and an existing stockholder, pursuant to which we 
issued and sold, in a registered direct offering, or the Registered Direct Offering: (i) an aggregate of 11,111,111 shares of our common stock, or Shares; and 
(ii) warrants to purchase up to 11,111,111 shares of common stock, or Warrants.

The combined purchase price of each Share and accompanying Warrant was $1.35. The exercise price for the Warrants is $1.62 per share. The 
Warrants will be exercisable from August 9, 2024 and will expire on August 9, 2029. The net proceeds to us from the Registered Direct Offering were 
approximately $13.9 million.

On January 31, 2024, or the Amendment Effective Date, we entered into a fourth amendment to the license agreement, or the Emory License 

Agreement, with Emory University and Georgia Tech Research Corporation (collectively, the “Licensor”) pursuant to which the parties agreed to reduce 
the Sublicense Percentage (as defined in the Emory License Agreement) from a low double digit percentage to a high single digit percentage that we will 
pay the Licensor applicable to any fees or payments paid to us by any Sublicensee (as defined in the Emory License Agreement) of the Licensed Patents 
and/or Licensed Technology (each as defined in the Emory License Agreement), on or after July 1, 2023, excluding (i) amounts paid to us by a Sublicensee 
to reimburse us for certain research and development costs pursuant to a written agreement between us and such Sublicensee, (ii) the value of intellectual 
property transferred or granted to us if necessary or helpful to the development or commercialization of Licensed Products (as defined in the Emory 
License Agreement) and (iii) amounts paid for shares of our stock. The payment to Licensor of any such Sublicense Percentage is due within 30 days of 
receipt by us of a qualifying payment from a Sublicensee, provided however, with respect to any qualifying payments received by us from a Sublicensee 
after July 1, 2023 but prior to January 1, 2025, the payment to Licensor of any such Sublicensee Percentage is due to Licensor by March 31, 2025. The 
parties also agreed to a revised annual license maintenance fee due each year, or the Maintenance Fee, starting in 2023 through 2028, as follows: $0.3 
million for 2023 through 2025, $0.4 million for 2026, $400,000 for 2027 and $0.5 million for 2028. We paid the Maintenance Fee for 2023 in February 
2024.  The remaining annual Maintenance Fee payments are due on October 1st of each year. 

On December 22, 2023, we, through our wholly owned subsidiary Royalty Sub, entered into a letter agreement, or the Letter Agreement, with HCR 

and HCR Clearside SPV, LLC (as assignee of HCR Collateral Management, LLC), or the Agent, amending that certain Purchase and Sale Agreement, 
dated as of August 8, 2022, by and among Royalty Sub, HCR and Agent.  Pursuant to the terms of the Letter Agreement, Royalty Sub and Agent mutually 
agreed that Royalty Sub waived any and all rights to the $12.5 million milestone payment which was deposited in an escrow account, or the First Milestone 
Payment, in connection with the closing of the transactions contemplated by the Purchase and Sale Agreement and agreed to the release of the First 
Milestone Payment to Agent. The First Milestone Payment was to be released to Royalty Sub upon attainment of a pre-specified XIPERE sales milestone if 
such milestone was achieved by March 31, 2024, or the First Milestone Event, or, at Agent’s option, in the event the First Milestone Event was not 
achieved.

On November 1, 2023, we, entered into a license agreement, or the BioCryst License Agreement, with BioCryst Pharmaceuticals, Inc., or BioCryst, 

pursuant to which we granted BioCryst an exclusive, worldwide and sublicensable license to our SCS Microinjector for the delivery of BioCryst’s 
proprietary plasma kallikrein inhibitor known as avoralstat for the treatment and prevention of diabetic macular edema, or DME. 

We received an upfront license fee payment of $5.0 million in connection with signing of the BioCryst License Agreement. In addition, we are 
eligible to receive up to an additional $30.0 million in clinical and regulatory milestone payments, and up to a total of $47.5 million in a series of post-
approval sales-based milestone payments based on the achievement of annual global net product sales milestones up to $2.0 billion. Further, during the 
royalty term, BioCryst has also agreed to pay us tiered mid-single digit royalties on annual global net product sales, with the highest royalty rate applied to 
sales over $1.5 billion, subject to reductions in specified circumstances. Our rights to these royalties and milestone payments have been sold pursuant to the 
terms and conditions of the Purchase and Sale Agreement described above in "Business—Royalty Purchase and Sale Agreement."

In May 2023, we terminated our at-the-market sales agreement with Cowen and Company, LLC, or the Prior ATM Agreement. We sold 515,959 

shares of its common stock for net proceeds of $0.7 million under the Prior ATM Agreement with Cowen and Company, LLC during the six months ended 
June 30, 2023, prior to the termination of the Prior ATM Agreement. During the year ended December 31, 2022, we sold 425,460 shares of common stock 
for net proceeds of $0.6 million under the Prior ATM Agreement. During the year ended December 31, 2021, we sold 2.9 million shares of common stock 
for net proceeds of $12.2 million under the Prior ATM Agreement.

In May 2023, we entered into a Controlled Equity OfferingSM Sales Agreement, or the Sales Agreement, with Cantor Fitzgerald & Co., or Cantor 

under which we may offer and sell, from time to time at its sole discretion, shares of its common stock, having an 

72

Table of Contents

aggregate offering price of up to $50.0 million through Cantor as our sales agent. During the year ended December 31, 2023, we sold 1,073,740 shares of 
our common stock for net proceeds of $1.1 million under the Sales Agreement. Subsequent to December 31, 2023, we sold an additional 339,912 shares of 
our common stock pursuant to the Sales Agreement for net proceeds of $0.5 million.

On August 8, 2022, or the Closing Date, we, through our wholly-owned subsidiary Clearside Royalty LLC, a Delaware limited liability company, or 

Royalty Sub, entered into a Purchase and Sale Agreement with entities managed by HealthCare Royalty Management, LLC, or HCR, pursuant to which 
Royalty Sub sold to HCR certain of its rights to receive royalty and milestone payments payable to Royalty Sub under the Arctic Vision License 
Agreement, Bausch License Agreement, that certain License Agreement, effective as of July 3, 2019, by and between us and Aura Biosciences, Inc., that 
certain Option and License Agreement, dated as of August 29, 2019, by and between REGENXBIO Inc. and us, and any and all out-license agreements 
following the Closing Date for, or related to XIPERE or the SCS Microinjector technology to be used in connection with compounds or products of any 
third parties delivered, in whole or in part, by means of the SCS Microinjector technology, excluding, for the avoidance of doubt, any in-licensed or 
internally developed therapies following the Closing Date, in exchange for up to $65 million. Under the terms of the Purchase and Sale Agreement, 
Royalty Sub received a payment of $32.1 million, representing the $32.5 million to which we were entitled less certain expenses. There were additional 
issuance costs of $1.5 million related to the Purchase and Sale Agreement resulting in net proceeds of $30.6 million. An additional $12.5 million was 
deposited in an escrow account, which was released to HCR pursuant to the Letter Agreement described above. The terms of the Purchase and Sale 
Agreement also provide for an additional $20 million milestone payment to Royalty Sub upon attainment of a second pre-specified sales milestone related 
to 2024 XIPERE sales. 

On January 6, 2021, we entered into a securities purchase agreement with certain institutional purchasers pursuant to which we issued and sold 4.2 

million shares of our common stock in a registered direct offering at a price of $2.851 per share. We raised net cash proceeds of $11.1 million after 
deducting offering expenses.

In April 2020, we entered into a loan agreement with Silicon Valley Bank under the terms of which Silicon Valley bank loaned us $1.0 million, or 
the PPP Loan, pursuant to the Paycheck Protection Program, or PPP, under the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act. In 
accordance with the requirements of the CARES Act, we used the proceeds primarily for payroll costs and other eligible expenses. The CARES Act and the 
PPP provide a mechanism for forgiveness of up to the full amount borrowed. On January 11, 2021, we received notification from Silicon Valley Bank that 
the PPP Loan was forgiven in full, including approximately $7,000 of accrued interest.

Pursuant to the Arctic Vision License Agreement, Arctic Vision paid us an upfront payment of $4.0 million in March 2020. In December 2021, we 
received a milestone payment of $4.0 million following receipt of FDA approval of XIPERE in the United States. In addition, Arctic Vision has agreed to 
pay us up to a total of $22.5 million in development and sales milestone payments.   Further, during the applicable royalty term, we will also be entitled to 
receive tiered royalties of 10-12% of net sales in the Arctic Territory, subject to customary reductions. In August 2021, we entered into an amendment to 
the Arctic Vision License Agreement to expand the territories covered by the license to include India and the ASEAN Countries (Brunei, Cambodia, 
Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam). In September 2021, we entered into a second amendment to the 
Arctic Vision License Agreement to expand the Arctic Territory to include Australia and New Zealand. We received an aggregate of $3.0 million in 
consideration for the expansion of the Arctic Territory.

In October 2019, we announced that Bausch acquired an exclusive license for the commercialization and development of XIPERE in the United 

States and Canada. On October 25, 2021, we announced that the FDA approved XIPERE for the treatment of macular edema associated with uveitis. We 
received a $5.0 million milestone payment from Bausch within 30 days of FDA approval. In December 2021, $10.0 million was recorded as revenue upon 
completion of pre-launch activities for XIPERE and the payment was received in January 2022. Bausch launched XIPERE in the United States in the first 
quarter of 2022. 

Funding Requirements

Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, research and development costs to build our 
product candidate pipeline, legal and other regulatory expenses and general overhead costs. In addition, we have certain contractual obligations for future 
payments.  Refer to Footnote 12 to our financial statements included this Annual Report on Form 10-K.

The successful development of our product candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, 
timing and estimated costs of the efforts that will be necessary to complete the remainder of the development of CLS-AX or any future product candidates. 
We are also unable to predict when, if ever, material net cash inflows will commence from product sales. This is due to the numerous risks and 
uncertainties associated with developing drugs, including the uncertainty of:

•

•

•

•

•

successful enrollment in, and completion of, clinical trials;

receipt of marketing approvals from applicable regulatory authorities;

establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our product candidates; and

launching commercial sales of the products, if and when approved, whether alone or in collaboration with others.

A change in the outcome of any of these variables with respect to the development of any of our product candidates would significantly change the 

costs and timing associated with the development of that candidate.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity 
offerings, debt financings and potential collaboration, license and development agreements. Other than potential payments we may receive under our 
license and other agreements, we do not currently have any committed external source of funds, though, as described above, we may also be able to sell our 
common stock under the ATM agreement with Cowen subject to the terms of that agreement and depending on market conditions. We expect that we will 
require additional capital to fund our ongoing operations. Additional funds may not be available to us on a timely basis, on commercially reasonable terms, 
or at all. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and disruptions to, and 
volatility in, the credit and financial markets in the United States and worldwide and related macroeconomic changes, such as rising inflation. To the extent 
that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of these 
securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity 
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 funds through additional collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, 
including any future collaboration or licensing arrangement for XIPERE outside of the territories in which we have previously licensed or granted options 
to license XIPERE, we may be required to relinquish additional rights to our technologies, future revenue streams, research programs or product candidates 
or to grant licenses on terms that may not be favorable to us. 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 drug development or future commercialization efforts or grant rights to develop and market product 
candidates that we would otherwise prefer to develop and market ourselves.

We also incur costs as a public company, including costs and expenses for fees to members of our board of directors, accounting and finance 
personnel costs, directors and officers insurance premiums, audit and legal fees, investor relations fees and expenses for compliance with reporting 
requirements under the Exchange Act and rules implemented by the SEC and Nasdaq.

Outlook

We have suffered recurring losses and negative cash flows from operations since inception and anticipate incurring additional losses until such time, 

if ever, that we can generate significant milestone payments and royalties from XIPERE and other licensing arrangements or revenues from other product 
candidates. We will need additional financing to fund our operations. Our plans primarily consist of raising additional capital, potentially in a combination 
of equity or debt financings, monetizing royalties, or restructurings, or potentially entering into additional collaborations, partnerships and other strategic 
arrangements.

Based on our current plans and forecasted expenses, we expect that our cash and cash equivalents as of the filing date, March 12, 2024, will enable us to 
fund our planned operating expenses and capital expenditure requirements into the third quarter of 2025. We have based this estimate on assumptions that 
may prove to be wrong, and we could exhaust our capital resources sooner than we expect. We will require additional capital in order to complete clinical 
development of CLS-AX.

During the years ended December 31, 2023, 2022 and 2021, our operating activities used net cash of $18.1 million, $13.4 million and $10.7 million, 
respectively. The net cash used in operating activities for the year ended December 31, 2023 as compared to the year ended December 31, 2022 was due to 
ongoing research and development expenses to develop our pipeline and ongoing costs for ODYSSEY, the Phase 2b clinical trial for CLS-AX, as well as 
the supporting general and administrative costs. This was partially offset by the receipt of research and development tax credits. The increase in cash used 
in operating activities for the year ended December 31, 2022 as compared to the year ended December 31, 2021 was primarily due to research and 
development expenses related to the preclinical and clinical programs offset by the receipt of the $10.0 million milestone payment received from Bausch in 
connection with pre-launch activities for XIPERE. 

In the year ended December 31, 2023 and 2022, our investing activities used net cash of $1.8 million and $0.2 million, respectively, for the purchase 

of machinery and equipment. 

During the years ended December 31, 2023, 2022 and 2021, our net cash provided by financing activities was $0.4 million, $31.3 million and $23.8 

million, respectively. The cash provided by financing activities for the year ended December 31, 2023 consisted primarily of $1.7 million of net proceeds 
from the sale of shares of our common stock under the ATM Agreement and the Sales Agreement partially offset by a payment of $1.4 million related to 
the Purchase and Sale agreement. The net cash provided by financing activities for the year ended December 31, 2022 was primarily comprised of $30.6 
million from the Purchase and Sale Agreement, net of issuance costs and $0.6 million of net proceeds from the sale of shares of our common stock under 
the ATM agreement. The net cash provided by financing activities for the year ended December 31, 2021 was primarily comprised of $11.1 million of net 
proceeds from the sale of shares of our common stock in a registered direct offering and $12.2 million of net proceeds from the sale of shares of our 
common stock under the ATM agreement.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and the Board of Directors of Clearside Biomedical, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Clearside  Biomedical,  Inc.  (the  Company)  as  of  December  31,  2023  and  2022,  the 
related consolidated statements of operations, stockholders' equity (deficit) and cash flows for each of the three years in the period ended December 31, 
2023, 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 at December 31, 2023 and 2022, and the results of its operations and its cash flows for 
each of the three years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial 
statements  based  on  our  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 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  financial  statements,  whether  due  to  error  or  fraud,  and 
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in 
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as 
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or 
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) 
involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion 
on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion 
on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of Liability Related to the Sales of Future Royalties, Net

Description of the 
Matter

How We Addressed 
the Matter in Our
Audit

As discussed in Note 5 to the consolidated financial statements, on August 8, 2022, the Company entered 
into a Royalty Purchase and Sale Agreement with a third party, pursuant to which the Company sold certain 
of its rights to receive royalty and milestone payments. The Company received proceeds of $32.1 million, 
representing  the  $32.5  million  to  which  the  Company  was  entitled,  net  of  certain  transaction  related 
expenses. The Company will repay the lender at a multiple of the initial proceeds received, which may vary 
based on timing and amount of cash flows received from its licensing partners.

The Company records the financing as a Liability related to the sales of future royalties, net on the balance 
sheet  at  its  carrying  value  of  $42.0  million  as  of  December  31,  2023.  The  Company  imputes  interest 
expense  associated  with  this  liability  using  the  effective  interest  rate  method.  Such  interest  expense  is 
recorded in the statement of operations for the year ended December 31, 2023 as Non-cash interest expense 
on liability related to the sales of future royalties. The effective interest rate is calculated based on the rate 
that would enable the estimated liability to be repaid in full over the anticipated life of the arrangement. The 
Company  utilizes  the  prospective  method  to  record  interest  expense  by  updating  its  estimate  of  the  new 
effective  interest  rate  each  period,  based  on  its  current  estimate  of  remaining  cash  flows  under  the 
arrangement.  The  Company  estimates  the  amount  and  timing  of  expected  payments  based  on    historical 
experience  and  its  expectations  of  future  activities  from  its  license  partners,  as  well  as  current  market 
conditions.

Auditing the liability related to the sales of future royalties, net was complex and highly judgmental due to 
the estimation uncertainty in determining the effective interest rate. The Company’s effective interest rate 
model includes cash flow projections for future royalty and milestone payments, which are sensitive to 
certain assumptions that are forward looking and could be affected by future market conditions. 

To test the liability related to the sales of future royalties, net as of December 31, 2023, our audit procedures 
included, among others, assessing the underlying data and significant assumptions used by the Company in 
determining  the  timing  and  amount  of  future  cash  flows  used  within  its  effective  interest  rate  model.  We 
assessed the reasonableness of the significant assumptions used in the cash flow projections by inspecting 
third  party  evidence  to  support  management’s  projections.    We  also  performed  a  comparison  of 
management’s prior projections of cash flow activity to actual results, and assessed the reasonableness of 
future  projections  based  on  activity  to  date.    We  recalculated  the  current  year  interest  expense  and 
performed sensitivity analyses to evaluate the changes in the effective interest rate, and associated interest 
expense, that would result from changes in the assumptions.

1. The Company

CLEARSIDE BIOMEDICAL, INC.

Notes to the Consolidated Financial Statements

Clearside Biomedical, Inc. (the “Company”) is a biopharmaceutical company focused on revolutionizing the delivery of therapies to the back of the 

eye through the suprachoroidal space (SCS). Incorporated in the State of Delaware on May 26, 2011, the Company has its corporate headquarters in 
Alpharetta, Georgia.

The Company’s activities since inception have primarily consisted of developing product and technology rights, raising capital and performing 

research and development activities. The Company is subject to a number of risks and uncertainties similar to those of other life science companies at a 
similar stage of development, including, among others, the need to obtain adequate additional financing, successful development efforts including 
regulatory approval of products, compliance with government regulations, successful commercialization of potential products, protection of proprietary 
technology and dependence on key individuals.

Liquidity

The Company had cash and cash equivalents of $28.9 million as of December 31, 2023. 

Historically, the Company has funded its operations primarily through the sale of common stock and convertible preferred stock, the issuance of 

long-term debt, and license agreements. On October 25, 2021, the Company announced that the U.S. Food and Drug Administration (the "FDA") approved 
XIPERE® (triamcinolone acetonide injectable suspension) for the treatment of macular edema associated with uveitis, a form of eye inflammation. In 
January 2022, the Company received $10.0 million from Bausch + Lomb, a division of Bausch Health Companies, Inc. ("Bausch"), upon completion of 
pre-launch activities for XIPERE pursuant to the license agreement granting Bausch an exclusive license to develop and commercialize XIPERE in the 
United States and Canada. Bausch launched XIPERE in the United States in the first quarter of 2022.

On February 6, 2024, the Company entered into a securities purchase agreement with institutional investors and an existing stockholder, pursuant to 
which the Company issued and sold, in a registered direct offering (the “Registered Direct Offering”): (i) an aggregate of 11,111,111 shares (the “Shares”) 
of its common stock; and (ii) warrants to purchase up to 11,111,111 shares of common stock (the “Warrants”).

The combined purchase price of each Share and accompanying Warrant was $1.35. The exercise price for the Warrants is $1.62 per share. The 
Warrants will be exercisable from August 9, 2024 and will expire on August 9, 2029. The net proceeds to the Company from the Registered Direct Offering 
were approximately $13.9 million.

On January 31, 2024 (the “Amendment Effective Date”), the Company entered into a fourth amendment to the license agreement (as amended, the 
“Emory License Agreement”) with Emory University and Georgia Tech Research Corporation (collectively, the “Licensor”) pursuant to which the parties 
agreed to reduce the Sublicense Percentage (as defined in the Emory License Agreement) from a low double digit percentage to a high single digit 
percentage that the Company will pay the Licensor applicable to any fees or payments paid to the Company by any Sublicensee (as defined in the Emory 
License Agreement) of the Licensed Patents and/or Licensed Technology (each as defined in the Emory License Agreement), on or after July 1, 2023, 
excluding (i) amounts paid to the Company by a Sublicensee to reimburse the Company for certain research and development costs pursuant to a written 
agreement between the Company and such Sublicensee, (ii) the value of intellectual property transferred or granted to the Company if necessary or helpful 
to the development or commercialization of Licensed Products (as defined in the Emory License Agreement) and (iii) amounts paid for shares of the 
Company’s stock. The payment to Licensor of any such Sublicense Percentage is due within 30 days of receipt by the Company of a qualifying payment 
from a Sublicensee, provided however, with respect to any qualifying payments received by the Company from a Sublicensee after July 1, 2023 but prior to 
January 1, 2025, the payment to Licensor of any such Sublicensee Percentage is due to Licensor by March 31, 2025. The parties also agreed to a revised 
annual license maintenance fee due each year (the “Maintenance Fee”) starting in 2023 through 2028, as follows: $250,000 for 2023 through 2025, 
$350,000 for 2026, $400,000 for 2027 and $500,000 for 2028. The Company paid the Maintenance Fee for 2023 in February 2024. The remaining annual 
Maintenance Fee payments are due on October 1st of each year. 

On December 22, 2023, Clearside Biomedical, Inc., through its wholly owned subsidiary Royalty Sub, entered into a letter agreement (the “Letter 
Agreement”) with HCR and HCR Clearside SPV, LLC (as assignee of HCR Collateral Management, LLC) (“Agent”) amending that certain Purchase and 
Sale Agreement, dated as of August 8, 2022, by and among Royalty Sub, HCR and Agent.  Pursuant to the terms of the Letter Agreement, Royalty Sub and 
Agent mutually agreed that Royalty Sub waived any and all 

84

Table of Contents

rights to the $12.5 million milestone payment which was deposited in an escrow account (“First Milestone Payment") in connection with the closing of the 
transactions contemplated by the Purchase and Sale Agreement and agreed to the release of the First Milestone Payment to Agent. The First Milestone 
Payment was to be released to Royalty Sub upon attainment of a pre-specified XIPERE sales milestone if such milestone was achieved by March 31, 2024 
(“First Milestone Event”) or, at Agent’s option, in the event the First Milestone Event was not achieved.

On November 1, 2023, the Company, entered into a license agreement (the “BioCryst License Agreement”) with BioCryst Pharmaceuticals, Inc. 
(“BioCryst”) pursuant to which the Company granted BioCryst an exclusive, worldwide and sublicensable license to the Company’s SCS Microinjector for 
the delivery of BioCryst’s proprietary plasma kallikrein inhibitor known as avoralstat for the treatment and prevention of diabetic macular edema (“DME”). 

The Company received an upfront license fee payment of $5.0 million in connection with signing of the BioCryst License Agreement. In addition, 
the Company is eligible to receive up to an additional $30.0 million in clinical and regulatory milestone payments, and up to a total of $47.5 million in a 
series of post-approval sales-based milestone payments based on the achievement of annual global net product sales milestones up to $2.0 billion. Further, 
during the royalty term, BioCryst has also agreed to pay the Company tiered mid-single digit royalties on annual global net product sales, with the highest 
royalty rate applied to sales over $1.5 billion, subject to reductions in specified circumstances. The Company’s rights to these royalties and milestone 
payments have been sold pursuant to the terms and conditions of the Purchase and Sale Agreement described above in in Note 5 to the consolidated 
financial statements.

In May 2023, the Company terminated its at-the-market sales agreement with Cowen and Company, LLC (the "ATM Agreement"). The Company 

sold 515,959 shares of its common stock for net proceeds of $0.7 million under its ATM Agreement with Cowen and Company, LLC during the six months 
ended June 30, 2023, prior to the termination of the ATM Agreement. During the year ended December 31, 2022, the Company sold 425,460 shares of its 
common stock for net proceeds of $0.6 million under its ATM Agreement. During the year ended December 31, 2021, the Company sold 2.9 million shares 
of its common stock for net proceeds of $12.2 million under its ATM Agreement.

In May 2023, the Company entered into a Controlled Equity OfferingSM Sales Agreement (the "Sales Agreement") with Cantor Fitzgerald & Co. 

("Cantor") under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering 
price of up to $50.0 million through Cantor as its sales agent. During the year ended December 31, 2023, the Company sold 1,073,740 shares of its 
common stock for net proceeds of $1.1 million under the Sales Agreement. Subsequent to December 31, 2023, the Company sold an additional 339,912 
shares of its common stock pursuant to the Sales Agreement for net proceeds of $0.5 million.

On August 8, 2022, the Company entered into a Purchase and Sale Agreement (the "Purchase and Sale Agreement") pursuant to which it sold its 
rights to receive royalty and milestone payments due to the Company from XIPERE and certain SCS Microinjector license agreements subject to a cap 
which may be increased under certain circumstances. The Company received a payment of $32.1 million in September 2022, representing the $32.5 million 
to which the Company was entitled, net of certain of HCR's transaction-related expenses which the Company agreed to reimburse. There were additional 
issuance costs of $1.5 million related to the Purchase and Sale Agreement resulting in net proceeds of $30.6 million.

On January 6, 2021, the Company entered into a securities purchase agreement with certain institutional purchasers that purchased 4.2 million 
shares of its common stock in a registered direct offering at a price of $2.851 per share. The Company raised net proceeds of $11.1 million after deducting 
offering expenses. 

In August 2021, the Company entered into an amendment to the Arctic Vision License Agreement (as defined in Note 10 - License and Other 

Agreements) to expand the territories covered by the license to include India and the ASEAN Countries (Brunei, Cambodia, Indonesia, Laos, Malaysia, 
Myanmar, the Philippines, Singapore, Thailand, and Vietnam).  In September 2021, the Company entered into a second amendment to the Arctic Vision 
License Agreement to expand the territories covered by the license to include Australia and New Zealand. The Company received an aggregate of $3.0 
million in consideration for the expansion of the licensed territory. 

Based on its current plans and forecasted expenses, the Company expects that its cash and cash equivalents as of the filing date, March 12, 2024 will 

enable it to fund its planned operating expenses and capital expenditure requirements into the third quarter of 2025. The Company has based this estimate 
on assumptions that may prove to be wrong, and it could exhaust its capital resources sooner than expected. Until the Company can generate sufficient 
revenue, the Company will need to finance future cash needs through public or private equity offerings, license agreements, debt financings or 
restructurings, collaborations, strategic alliances and marketing or distribution arrangements.

2. Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company's consolidated financial statements include the results of the financial operations of Clearside Biomedical, Inc. and its wholly-owned 

subsidiary, Clearside Royalty LLC. a Delaware limited liability company, which was formed for the purposes of the transactions contemplated by the 
Purchase and Sale Agreement described in Note 5. All intercompany balances and transactions have been eliminated.

The Company’s financial statements have been prepared in conformity with accounting principles generally accepted in the United States of 

America (“U.S. GAAP”).

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that 

affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and 
reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include the estimate of 
the total amount of future royalty revenue and milestone payments to be generated over the life of the Purchase and Sale Agreement, revenue recognition, 
the accounting for useful lives to calculate depreciation and amortization, clinical trial expense accruals, share-based compensation expense and income tax 
valuation allowance. Actual results could differ from these estimates.

Revenue Recognition

The Company recognizes revenue from its contracts with customers under Financial Accounting Standards Board Accounting Standards 
Codification (“ASC”) Topic 606, Revenue from Contracts with Customers. The Company’s primary revenue arrangements are license agreements which 
typically include upfront payments, regulatory and commercial milestone payments and royalties based on future product sales. The arrangements may also 
include payments for the Company’s SCS Microinjector devices as well as payments for assistance and oversight of the customer’s use of the Company’s 
technology. In determining the amount of revenue to be recognized under these agreements, the Company performs the following steps: (i) identifies the 
promised goods and services to be transferred in the contract, (ii) identifies the performance obligations, (iii) determines the transaction price, (iv) allocates 
the transaction price to the performance obligations and (v) recognizes revenue as the performance obligations are satisfied.

The Company receives payments from its customers based on billing schedules established in each contract. Up-front and other payments may 
require deferral of revenue recognition to a future period until the Company performs its obligations under the arrangement. Amounts are recorded as 
accounts receivable when the Company’s right to consideration is unconditional. The Company does not assess whether a contract has a significant 
financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised 
goods or services to the customer will be one year or less.

In the year ended December 31, 2023, 2022, and 2021, the Company recognized $8.2 million, $1.3 million, and $29.6 million of revenue associated 

with its license agreements, respectively. License revenue for the year ended December 31, 2023 was primarily for a non-refundable $5.0 million upfront 
license fee payment from BioCryst and $1.4 million of milestone payments from Aura Biosciences, Inc. The $5.0 million non-refundable upfront payment 
was recognized upon transfer of control of the license to BioCryst. The $1.4 million in milestone payments from Aura were recognized upon satisfaction of 
the related performance obligations. Remaining revenues for the year ended December 31, 2023 were generated by providing training materials and clinical 
trial products to the Company's licensees. License revenue for the year ended December 31, 2022 was primarily from providing training materials and 
clinical trial products to the Company's licensees. License revenue for the year ended December 31, 2021 was primarily a result of (i) the milestone 
payments from Bausch that consisted of $5.0 million received upon FDA approval of XIPERE, the recognition of $5.0 million of deferred revenue for the 
upfront milestone payment and the recognition of a $10.0 million milestone for pre-launch activities and (ii) an aggregate of $8.0 million received from 
Arctic Vision for FDA approval of XIPERE, territory expansion and certain development milestones.

Segment Information 

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief 

operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its 
operations and manages its business in one operating segment. 

86

Table of Contents

Property and Equipment, Net 

Property and equipment is recorded at historical cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the 

related assets, or for leasehold improvement the lesser of the useful life or remaining lease term. Repairs and maintenance are expensed when incurred. 
Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain 
or loss is included in the determination of net income. 

Debt Discount 

All debt discounts are recorded against the related debt obligation and are amortized using the effective interest rate method over the term of the 

underlying debt obligation and reflected in interest expense. 

Income Taxes

Deferred tax assets or liabilities are recorded for temporary differences between financial statement and tax basis of assets and liabilities, using 
enacted rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that a 
deferred tax asset will not be realized. The Company has provided a full valuation allowance on its deferred tax assets, which primarily consist of 
cumulative net operating losses for the period from May 26, 2011 (inception) to December 31, 2023. Due to its history of operating losses since inception 
and losses expected to be incurred in the foreseeable future, a full valuation allowance was considered necessary. 

Liabilities for uncertain tax positions are recognized based on a two-step process. The first step is to evaluate the tax position for recognition by 

determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of 
related appeals or litigation processes, if any. Once it is determined that the position meets the recognition threshold, the second step requires estimating 
and measuring the largest amount of tax benefit that is more likely than not to be realized upon ultimate settlement. The difference between the amount of 
recognizable tax benefit and the total amount of tax benefit from positions filed or to be filed with the tax authorities is recorded as a liability for uncertain 
tax benefits.

Research and Development Costs

Research and development costs are charged to expense as incurred and include:

•

•

•

•

•

•

•

•

employee-related expenses, including salaries, benefits, travel and share-based compensation expense for research and development 
personnel;

expenses incurred under agreements with contract research organizations, contract manufacturing organizations and consultants that conduct 
preclinical studies and clinical trials;

costs associated with preclinical and clinical development activities;

costs associated with submitting regulatory approval applications for the Company’s product candidates;

costs associated with training physicians on the suprachoroidal injection procedure and educating and providing them with appropriate 
product candidate information;

costs associated with technology and intellectual property licenses;

costs for the Company’s research and development facility; and

depreciation expense for assets used in research and development activities.

Costs for certain development activities, such as clinical trial activities, are recognized based on an evaluation of the estimated total costs for the 

clinical trial, progress to completion of specific tasks, using data such as patient enrollment, pass through expenses, clinical site activations, data from the 
clinical sites or information provided to the Company by its vendors on their actual costs incurred. Payments for these activities are based on the terms of 
the individual contracts and any subsequent amendments, which may differ from the patterns of costs incurred, and are reflected in the financial statements 
as prepaid or accrued expenses. 

87

Table of Contents

Share-Based Compensation

Compensation cost related to share-based awards granted to employees, directors and consultants is measured based on the estimated fair value of 
the award at the grant date. The fair value of restricted stock units granted is measured based on the market value of the Company’s common stock on the 
date of grant. Share-based compensation costs are expensed on a straight-line basis over the relevant vesting period. 

Compensation cost related to shares purchased through the Company’s employee stock purchase plan, which is considered compensatory, is based 

on the estimated fair value of the shares on the offering date, including consideration of the discount and the look back period. The Company estimates the 
fair value of the shares using a Black-Scholes option pricing model. Compensation expense is recognized over the six-month withholding period prior to 
the purchase date.

All share-based compensation costs are recorded in general and administrative or research and development costs in the statements of operations 

based upon the underlying employees’ roles within the Company.

Cash Equivalents

Cash equivalents consist of short-term, highly liquid investments with an original term of three months or less at the date of purchase.

Restricted Cash

The Company is required to maintain a stand-by letter of credit as a security deposit for its facility lease in Alpharetta, Georgia. The Company’s 

bank requires the Company to maintain a restricted cash balance to serve as collateral for the letter of credit issued to the landlord by the bank. As of 
December 31, 2022, the restricted cash balance was invested in a commercial money market account. The current portion of the restricted cash is recorded 
in other current assets and the long-term portion is recorded in restricted cash.

Concentration of Credit Risk Arising From Cash Deposits in Excess of Insured Limits

The Company maintains its cash in bank deposits that at times may exceed federally insured limits. The Company has not experienced any loss in 

such accounts. The Company believes it is not exposed to any significant risks with respect to its cash balances.

Liability Related to the Sales of Future Royalties and Non-Cash Interest Expense 

In connection with the Purchase and Sale Agreement, the Company recognized a liability related to the sales of future royalties under ASC 470-10 

Debt and ASC 835-30 Interest - Imputation of Interest. The initial funds received by the Company pursuant to the terms of the Purchase and Sale 
Agreement were recorded as a liability and are accreted under the effective interest method up to the estimated amount of future royalties and milestone 
payments to be made under the Purchase and Sale Agreement. The issuance costs were recorded as a direct deduction to the carrying amount of the liability 
and are being amortized under the effective interest method over the estimated period the liability will be repaid. The Company estimates the total amount 
of future royalty revenue and milestone payments to be generated over the life of the Purchase and Sale Agreement, and a significant increase or decrease 
in these estimates could materially impact the liability balance and the related interest expense. If the timing of the receipt of royalty payments or 
milestones is materially different from the original estimates, the Company will prospectively adjust the effective interest and the related amortization of 
the liability and related issuance costs.

5. Royalty Purchase and Sale Agreement

On August 8, 2022 (the “Closing Date”), the Company, through its wholly-owned subsidiary Clearside Royalty LLC, a Delaware limited liability 

company (“Royalty Sub”), entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”) with entities managed by HealthCare Royalty 
Management, LLC (“HCR”), pursuant to which Royalty Sub sold to HCR certain of its rights to receive royalty and milestone payments payable to Royalty 
Sub under the Arctic Vision License Agreement, the Bausch License Agreement, that certain License Agreement, effective as of July 3, 2019, by and 
between the Company and Aura Biosciences, Inc. (the “Aura License Agreement”), that certain Option and License Agreement, dated as of August 29, 
2019, by and between REGENXBIO Inc. and the Company (the “REGENXBIO License Agreement”) and any and all out-license agreements following the 
Closing Date for, or related to XIPERE  or the SCS Microinjector technology (to be used in connection with compounds or products of any third parties) 
delivered, in whole or in part, by means of the SCS Microinjector technology), excluding, for the avoidance of doubt, any in-licensed or internally 
developed therapies following the Closing Date (collectively, the “Royalties”), in exchange for up to $65 million. In connection with this transaction, the 
Company assigned the Arctic Vision License Agreement, Bausch License Agreement, Aura License Agreement, REGENXBIO License Agreement, the 
Company's license agreement with Emory University and The Georgia Tech Research Corporation and related intellectual property rights to Royalty Sub.  

Under the terms of the Purchase and Sale Agreement, Royalty Sub received an initial payment of $32.1 million, representing the $32.5 million to 

which the Company was entitled, net of certain of HCR's transaction-related expenses which the Company agreed to reimburse. There were additional 
issuance costs of $1.5 million related to the Purchase and Sale Agreement resulting in net proceeds of $30.6 million. An additional $12.5 million (the "First 
Milestone Payment") was deposited by HCR in an escrow account which was released to HCR pursuant to the Letter Agreement described below. The 
terms of the Purchase and Sale Agreement also provide for an additional $20 million milestone payment to Royalty Sub upon attainment of a second pre-
specified sales milestone related to 2024 XIPERE sales (the "Second Milestone Event").

The Purchase and Sale Agreement will automatically expire, and the payment of Royalties from the Royalty Sub to HCR will cease, when HCR has 

received payments of the Royalties equal to 2.5 times the aggregate amount of payments made by HCR under the Agreement if the Second Milestone 
Event is achieved on or prior to December 31, 2024 (the “Initial Cap”). If the Second Milestone Event is not achieved on or prior to December 31, 2024, 
payment of Royalties from Royalty Sub to HCR will cease when HCR has received Royalties payments equal to 3.4 times the aggregate amount of 
payments under the Purchase and Sale Agreement (the “Alternative Cap”, and together with the Initial Cap, the “Cap Amount”).  In the event of a change 
in control, acquiror will have the option to make a payment to HCR of the Cap Amount then in effect, less the aggregate amount of Royalty payments made 
by Royalty Sub to HCR under the Purchase and Sale Agreement as a one-time payment at which time, payment of Royalties to HCR will cease.  
Alternatively, in the event of a change in control, the acquiror will have the option to make an initial payment of 1.0 times the aggregate amount of 
payments made by HCR under the Purchase and Sale Agreement as of the date of such change in control, then in that event, payment of Royalties from 
Royalty Sub to HCR will cease when HCR has received total Royalties payments (including the initial payment) equal to the Alternative Cap. After the 
Purchase and Sale Agreement expires, all rights to receive the Royalties return to Royalty Sub.

On December 22, 2023, the Company, through its wholly owned subsidiary Royalty Sub, entered into the Letter Agreement with the Agent 
amending that certain Purchase and Sale Agreement, dated as of August 8, 2022, by and among Royalty Sub, HCR and Agent. Pursuant to the terms of the 
Letter Agreement, Royalty Sub and Agent mutually agreed that Royalty Sub waived any and all rights to the First Milestone Payment in connection with 
the closing of the transactions contemplated by the Purchase and Sale Agreement and agreed to the release of the First Milestone Payment to Agent.

Issuance costs pursuant to the Purchase and Sale Agreement consisting primarily of advisory and legal fees, totaled $1.9 million including the 

amount of HCR's transaction-related expenses that the Company reimbursed. The effective interest rate includes cash flow projections for future royalty 
and milestone payments that are forward looking and could be affected by future market conditions. The Company estimates the amount and timing of 
expected payments based on historical experience and its expectations of future activities from its license partners, as well as current market conditions.

6. CARES Act Paycheck Protection Program Loan

On April 20, 2020, the Company entered into a loan agreement with SVB (the “PPP Lender”) under the terms of which the PPP Lender made a loan 

to the Company in an aggregate principal amount of $1.0 million (the “PPP Loan”) pursuant to the Paycheck Protection Program (the “PPP”) under the 
Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The PPP Loan was evidenced by a promissory note (the “Note”) containing the 
terms and conditions for repayment of the PPP Loan.

Under the terms of the Note and the PPP Loan, interest accrued on the outstanding principal amount at the rate of 1.0% per annum. The term of the 

Note was until April 2022, with the Company obligated to make equal monthly payments of principal and interest, beginning in November 2020 and 
continuing until the maturity date.

The CARES Act and the PPP provide a mechanism for forgiveness of up to the full amount borrowed. On January 11, 2021, the Company was 

notified by the PPP Lender that the PPP Loan had been forgiven in full, including approximately $7,000 of accrued interest. In accordance with ASC 405-
20, Extinguishment of Liabilities, the income from the forgiveness of the amount borrowed and the accrued interest was recognized in the statement of 
operations in other income as a gain on extinguishment of debt.

7. Preferred and Common Stock

The Company’s amended and restated certificate of incorporation authorizes the Company to issue 10,000,000 shares of $0.001 par value of 

preferred stock. As of December 31, 2023 and 2022, there were 10,000,000 shares of preferred stock authorized, none of which were issued and 
outstanding.

At the Company's Annual Meeting of Stockholders held on June 22, 2022, the Company's stockholders approved an amendment to the amended and 

restated certificate of incorporation to increase the Company's authorized number of shares of common stock from 100,000,000 shares to 200,000,000 
shares. As of December 31, 2023 the Company was authorized to issue 200,000,000 shares of $0.001 par value common stock.  As of December 31, 2023 
and 2022, there were 62,850,841 and 60,639,827 shares of common stock outstanding, respectively.

8. Common Stock Warrants

In September 2016, in connection with a loan agreement, the Company issued warrants to the lenders to purchase up to 29,796 shares of common 

stock at a price per share of $10.74. The warrants are fully exercisable and expire in September 2026, or earlier upon the occurrence of specified mergers or 
acquisitions of the Company. The warrants were recorded in equity at the time of issuance and had a remaining life of 2.75 years as of December 31, 2023.

On February 6, 2024, the Company entered into a securities purchase agreement with institutional investors and an existing stockholder, pursuant to 

which the Company issued and sold, in a registered direct offering  (i) an aggregate of 11,111,111 shares (the “Shares”) of its common stock; and (ii) 
warrants to purchase up to 11,111,111 shares of common stock (the “Warrants”).

The combined purchase price of each Share and accompanying Warrant was $1.35. The exercise price for the Warrants is $1.62 per share. The 

Warrants will be exercisable from August 9, 2024 and will expire on August 9, 2029. 

9. Share-Based Compensation

Stock Options

In January 2016, the Company’s board of directors adopted and approved the Clearside Biomedical, Inc. 2016 Equity Incentive Plan (the “2016 

Plan”) which became effective on June 1, 2016. The 2016 Plan provides for the grant of share-based awards to employees, directors and consultants of the 
Company. The 2016 Plan provides for the grant of incentive stock options to employees, and for the grant of nonqualified stock options, restricted stock 
awards, restricted stock unit awards, stock appreciation rights, performance stock awards and other forms of stock compensation to the Company’s 
employees, directors, and non-employee third parties. The number of shares of common stock reserved for issuance under the 2016 Plan will automatically 
increase on January 1 each year, through January 1, 2026, by 4% of the total number of shares of the Company’s common stock outstanding on December 
31 of the preceding calendar year, or a lesser number of shares as may be determined by the Company’s board of directors. At December 31, 2023, under 
the 2016 Plan, options to purchase 9,638,424 shares of the Company’s common stock were outstanding at a weighted average price of $2.79 per share and 
570,024 shares remained available for future grant. As of January 1, 2024, the number of shares of common stock that may be issued under the 2016 Plan 
was automatically increased by 2,514,033 shares, representing 4% of the total number of shares of common stock outstanding on December 31, 2023, 
increasing the number of shares of common stock available for issuance under the 2016 Plan as of that date to 3,084,057 shares.

As a result of the adoption of the 2016 Plan, no further grants may be made under the Company’s 2011 Stock Incentive Plan (the “2011 Plan”). The 

2011 Plan provided for the grant of share-based awards to employees, directors and consultants of the Company. At December 31, 2023, options to 
purchase 210,110 shares of the Company’s common stock were outstanding under the 2011 Plan at a weighted average exercise price of $4.28 per share.

Share-based compensation is accounted for in accordance with the provisions of ASC 718, Compensation-Stock Compensation. The estimated fair 
value of options granted is determined as of the date of grant using the Black-Scholes option pricing model. The resulting fair value is recognized ratably 
over the requisite service period, which is generally the vesting period of the awards. 

The following table sets forth the weighted average assumptions utilized in the Black-Scholes option pricing model to calculate the fair value of the 

underlying common stock for the years ended December 31, 2023, 2022 and 2021.

Expected term (in years): In the years ended December 31, 2023 and 2022, the Company used historical data to calculate the expected term. In the 
year ended December 31, 2021, the Company utilized the simplified method as prescribed by ASC 718, as the Company did not have sufficient historical 
exercise and post-vesting termination data to provide a reasonable basis upon which to estimate the expected term of stock options granted to employees.

Risk-free interest rate: The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected time to a 

possible liquidity event.

Expected dividend yield: The Company has not paid and does not anticipate paying any dividends in the foreseeable future. 

Expected stock price volatility: The Company calculates expected volatility based on the historical volatility of its common stock. 

Forfeitures: The Company records forfeitures as they occur.

As of December 31, 2023, the Company had $4.1 million of unrecognized compensation expense related to unvested stock options, which is 
expected to be recognized over a weighted average period of 2.3 years. The weighted average fair values of all stock options granted for the years ended 
December 31, 2023, 2022 and 2021 was $0.98 per share, $1.55 per share and $3.24 per share, respectively. The intrinsic value is calculated as the 
difference between the fair market value and the exercise price per share of the stock options. The fair market value per share of common stock as of 
December 29, 2023 was $1.17, which was the closing sale price of the Company’s common stock on the Nasdaq Global Market on that date.

Restricted Stock Units

The Company has granted restricted stock units (“RSUs”) to employees under the 2016 Plan. The shares underlying the RSU awards have vesting 
terms of four years from the date of grant, subject to the employees’ continuous service and subject to accelerated vesting in specified circumstances. The 
fair value of the RSUs granted is measured based on the market value of the Company’s common stock on the date of grant and is recognized ratably over 
the requisite service period, which is generally the vesting period of the awards.

will automatically increase on January 1 of each year, through January 1, 2026, by the lesser of (i) 1% of the total number of shares of the Company’s 
common stock outstanding on December 31 of the preceding calendar year, (ii) 454,545 shares of common stock or (iii) a lesser number of shares as may 
be determined by the Company’s board of directors. The Company’s board of directors elected not to increase the shares reserved for issuance on January 
1, 2024. The number of shares of common stock available for issuance under the 2016 ESPP as of December 31, 2023 was 348,782 shares. 

The 2016 ESPP is considered a compensatory plan and the fair value of the discount and the look-back period are estimated using the Black-Scholes 

option pricing model and expense is recognized over the six-month withholding period prior to the purchase date. During the years ended December 31, 
2023, 2022 and 2021, the Company issued 68,109, 66,919 and 65,481 shares, respectively, of common stock purchased under the 2016 ESPP.

Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary 

differences is reported as deferred income taxes. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, 
based on available evidence, is not expected to be realized. The Company establishes a valuation allowance for deferred tax assets for which realization is 
not likely. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of 
deferred tax assets. 

At December 31, 2023, the Company had a valuation allowance of $84.0 million recorded against the benefit of certain deferred tax assets. The 

valuation allowance was primarily related to federal and state net operating loss ("NOL") carryforwards that, in the judgment of management, are not more 
likely than not to be realized. In assessing the recoverability of the Company’s deferred tax assets, management considered, among other things, its deferred
tax liabilities, its historical earnings and losses, projections of future income, and tax-planning strategies available to the Company in the relevant 
jurisdiction. The Company will release this valuation allowance when management determines that it is more likely than not that its deferred tax asset will 
be realized.

At December 31, 2023, the Company had income tax NOL carryforwards for federal and state purposes of $225.9 million and $89.3 million, 
respectively. The Company has recorded a deferred tax asset for both federal and state NOL carryforwards of $47.4 million and $5.6 million, respectively. 
If not utilized, the federal NOL carryforwards will begin to expire beginning in 2034, and the state NOL carryforwards will begin to expire at various dates 
beginning in 2027. Additionally, under the 2017 Tax Cuts and Jobs Act, federal net operating losses incurred in 2018 and beyond may be carried forward 
indefinitely. However, the deductibility of such federal net operating losses is limited beginning in 2021. Certain states have also adopted the indefinite 
carryforward period beginning with the 2018 tax year, but state conformity varies state by state. 

Liabilities for uncertain tax positions are recognized based on a two-step process. The first step is to evaluate the tax position for recognition by 

determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of 
related appeals or litigation processes, if any. Once it is determined that the position meets the recognition threshold, the second step requires the Company 
to estimate and measure the largest amount of tax benefit that is more likely than not to be realized upon ultimate settlement. The difference between the 
amount of recognizable tax benefit and the total amount of tax benefit from positions filed or to be filed with the tax authorities is recorded as a liability for 
uncertain tax benefits.

The following is a roll forward of the Company’s uncertain tax positions (in thousands):

Balance of uncertain tax positions at the beginning of the year

As of December 31, 2023 and 2022, there was $7.5 million in each period of unrecognized tax benefit that if recognized would be in the form of a 

net operating loss carryforward, which is expected to require a full valuation allowance based on present circumstances. The Company reversed $48,000 of 
previously recorded unrecognized tax expenses for the year 2021. The Company recognizes accrued interest related to unrecognized tax expenses and 
penalties as income tax expense. No significant amounts of interest or penalties have been recorded as of December 31, 2023.

Ownership changes, as defined by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), may limit the amount of net 
operating losses that a company may utilize to offset future taxable income and taxes payable. In general, if the Company experiences a greater than 50% 
aggregate change in ownership over a 3-year period (a Section 382 ownership change), utilization of the Company’s pre-change NOL carryforwards may 
be subject to limitation under the Code. The annual limitation generally is determined by multiplying the value of the Company’s stock at the time of such 
ownership change (subject to certain adjustments) by the applicable long-term tax-exempt rate for the month in which the ownership change occurred. Such 
limitation may result in expiration of a portion of the NOL carryforwards before utilization. The Company has completed an owner shift analysis to 
determine the dates in which the Company may have experienced a Section 382 ownership change, and determined that the Company experienced 
ownership changes for Section 382 purposes in January 2012, December 2013, and July 2016. Further, the Company has determined that $38,000 and 
$2,000 of its deferred tax asset related to Federal NOL and Federal R&D Credit, respectively, will expire due to Section 382.

The NOL DTA has a full valuation allowance as it is deemed that it is more likely than not to be utilized.  The Company will continue to monitor 

equity movement and its impact on the utilization of the NOLs and credits.  The Company’s ability to use the remaining NOL carryforwards may be further 
limited if the Company experiences an additional Section 382 ownership change as a result of future changes in its stock ownership. 

The Company is subject to taxation in the United States and certain state jurisdictions. As of December 31, 2023, the Company’s tax returns for 
2020, 2021 and 2022 are subject to full examination by the tax authorities. As of December 31, 2023, the Company is generally no longer subject to state or 
local examinations by tax authorities for years before 2020, except to the extent of NOLs generated in prior years claimed on a tax return.  

11. Commitments and Contingencies

Lease Commitment Summary

The Company leases its facilities and some of its equipment under noncancelable operating lease arrangements that expire at various dates through 
2026. In November 2022, the Company singed an amended office lease agreement and decreased the square footage to approximately 14,000 square feet. 
The amended office lease agreement is for a four-year term with a renewal option for an additional thirty-eight months. Rental payments are $30,437 per 
month subject to an increase of 3% per year. Operating lease cost under this lease and the amendment is recognized on a straight-line basis over the term of 
the lease. In addition, the office lease agreement requires payment of the pro-rata share of the annual operating expenses associated with the premises. 

The Company’s operating leases included on the balance sheet are as follows (in thousands):

The Company recognizes a right-of-use asset for the right to use the underlying asset for the lease term, and a lease liability, which represents the 
present value of the Company’s obligation to make payments over the lease term. The renewal option is not included in the calculation of the right-of-use 
asset and the lease liabilities as the Company is not reasonably certain if the Alpharetta, Georgia lease will be renewed. The present value of the lease 
payments is calculated using an incremental borrowing rate as the Company’s leases do not provide an implicit interest rate. At December 31, 2023, the 
Company’s incremental borrowing rate was 8.0% and the remaining lease term was 3.0 years. Cash payments included in operating activities on the 
consolidated statement of cash flows for operating lease liabilities were $362,000, $339,000 and $392,000 for the years ended December 31, 2023, 2022 
and 2021, respectively.

Equipment leases with an initial term of 12 months or less are not recorded with operating lease liabilities. The Company recognizes expense for 

these leases on a straight-line basis over the lease term. The equipment leases were deemed to be immaterial. 

Operating lease cost was $339,000, $262,000 and $247,000 for  the years ended December 31, 2023, 2022 and 2021. Variable lease cost was 
$19,000, $87,000 and $95,000 for  the years ended December 31, 2023, 2022 and 2021. Short-term lease cost was $93,000, $86,000 and $12,000 for the 
years ended December 31, 2023, 2022 and 2021, respectively. 

Georgia Tech License Agreement

As described in Footnote 1, the Company entered into a fourth amendment to the Georgia Tech License Agreement pursuant to which the parties 
agreed to revised Maintenance Fee payments. The Company paid the Maintenance Fee for 2023 in February 2024. The remaining annual Maintenance Fee 
payments are due on October 1st of each year from 2024 through 2028, as show in the table below. 

The annual Maintenance Fee will be paid as follows (in thousands):

In the course of the Company’s normal business operations, it has agreements with contract service providers to assist in the performance of its 

research and development, clinical research and manufacturing. Substantially all of these contracts are on an as needed basis.

In May 2018, the Company entered into a manufacturing supply agreement (the “Supply Agreement”), with Gerresheimer Regensburg GmbH, a 

company incorporated under the laws of Germany (“Gerresheimer”). Gerresheimer will manufacture and supply the Company’s proprietary SCS 
Microinjector. The Company will provide Gerresheimer with a rolling forecast schedule of its projected purchase orders for at least the next four calendar 
quarters. The Supply Agreement contains an initial five-year term that will automatically renew for successive periods of three years, unless terminated by 
either party at least 12 months prior to the end of the applicable term.

12. License and Other Agreements

Bausch + Lomb

On October 22, 2019, the Company entered into a License Agreement (as amended, the "Bausch License Agreement") with Bausch + Lomb, a 
division of Bausch Health Companies, Inc. (“Bausch”). Pursuant to the Bausch License Agreement, the Company has granted an exclusive license to 
Bausch to develop, manufacture, distribute, promote, market and commercialize XIPERE using the Company’s proprietary SCS Microinjector (the 
“Device”), as well as specified other steroids, corticosteroids and NSAIDs in 

97

 
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

combination with the Device (“Other Products,” and together with XIPERE, the “Products”), subject to specified exceptions, in the United States and 
Canada (the “Territory”) for the treatment of ophthalmology indications, including non-infectious uveitis.  

Pursuant to the Bausch License Agreement, Bausch paid the Company an upfront payment of $5.0 million (the “Upfront Payment”) in October 
2019. In October 2021, the FDA approved XIPERE. The Company received $5.0 million from Bausch as a result of the approval. In December 2021, $10.0 
million was recorded upon completion of pre-launch activities for XIPERE and payment was received in January 2022.  In addition, Bausch has agreed to 
pay up to an aggregate of $55.0 million in additional milestone payments upon the achievement of (i) specified regulatory approvals for specified 
additional indications of XIPERE  and (ii) specified levels of annual net sales (as defined in the Bausch License Agreement). Further, during the applicable 
royalty term, the Company will also be entitled to receive tiered royalties at increasing percentages, from the high-teens to twenty percent, based on 
XIPERE achieving certain annual net sales thresholds in the Territory, in each case subject to reductions in specified circumstances; provided that the 
Company will not receive any royalties on the first $45.0 million of cumulative net sales of all products in the Territory. Bausch launched XIPERE in the 
United States in the first quarter of 2022. The Company's rights to these royalties and milestone payments have been sold pursuant to the terms and 
conditions of the Purchase and Sale Agreement described in Note 5 to the consolidated financial statements.

The Company was responsible for all development expenses for XIPERE in the Territory until the Company's New Drug Application ("NDA") was 
approved by the FDA, subject to specified exceptions, as well as manufacturing costs in connection with the NDA. The Company was also responsible for 
all clinical and development expenses conducted to satisfy the FDA’s requests in the complete response letter issued on October 18, 2019 related to the 
NDA and any subsequent complete response letter related to the NDA. Following FDA approval of XIPERE, Bausch is responsible for all such expenses.

Due to the refund provisions in the Bausch License Agreement, the Upfront Payment was included on the balance sheet as deferred revenue as of 

December 31, 2020. The refund provisions lapsed upon FDA approval of XIPERE and the $5.0 million was recognized as revenue in the fourth quarter of 
2021.

REGENXBIO, Inc.

On August 29, 2019, the Company entered into an option and license agreement with REGENXBIO, Inc. (“REGENXBIO”) pursuant to which the 

Company granted REGENXBIO an exclusive option to enter into a commercial license agreement (the “Option”), which grants REGENXBIO an 
exclusive, worldwide and sublicensable license to the Company’s SCS Microinjector for the delivery of adeno-associated virus-based gene therapies for the 
treatment of wet age-related macular degeneration, diabetic retinopathy and other conditions for which anti-vascular endothelial growth factor treatment is 
currently the standard of care. REGENXBIO exercised the Option in October 2019 and paid the Company an option fee equal to $2.0 million, less a credit 
of $0.5 million previously received under a technology access agreement. In addition, REGENXBIO has agreed to pay the Company up to an aggregate of 
$31.0 million in milestone payments upon the achievement of specified development milestones and up to an aggregate of $102.0 million in sales-based 
milestone payments, as well as mid-single digit royalties on net sales of products using the SCS Microinjector during the royalty term. In September 2020, 
the Company received $3.0 million in milestone payments under the Option. The Company's rights to these royalties and milestone payments have been 
sold pursuant to the terms and conditions of the Purchase and Sale Agreement described in Note 5 to the consolidated financial statements.

Arctic Vision (Hong Kong) Limited

On March 10, 2020, the Company entered into a License Agreement (the “Arctic Vision License Agreement”) with Arctic Vision (Hong Kong) 

Limited (“Arctic Vision”). Pursuant to the Arctic Vision License Agreement, the Company has granted an exclusive license to Arctic Vision to develop, 
distribute, promote, market and commercialize XIPERE, subject to specified exceptions in China, Hong Kong, Macau, Taiwan and South Korea (the 
“Arctic Territory”). Under the terms of the Arctic Vision License Agreement, neither party may commercialize XIPERE in the other party’s territory. Arctic 
Vision has agreed to use commercially reasonably efforts to pursue development and commercialization of XIPERE for indications associated with uveitis 
in the Arctic Territory. In addition, upon receipt of the Company’s consent, Arctic Vision will have the right, but not the obligation, to develop and 
commercialize XIPERE for additional indications in the Arctic Territory.

Pursuant to the Arctic Vision License Agreement, Arctic Vision paid the Company an upfront payment of $4.0 million in March 2020. In December 

2021, the Company received a milestone payment of $4.0 million following the receipt of FDA approval of XIPERE in the United States. In addition, 
Arctic Vision has agreed to pay the Company up to $22.5 million in development and sales milestones. Further, during the applicable royalty term, the 
Company will also be entitled to receive tiered royalties of ten to twelve percent of net sales based on achieving certain annual net sales thresholds in the 
Arctic Territory, subject to customary reductions, payable on a product-by-product and country-by-country basis, commencing at launch in such country 
and lasting until the latest of (i) the date that all valid claims within the licensed patent rights covering XIPERE have expired, (ii) the date of the loss of 
marketing or 

98

Table of Contents

regulatory exclusivity of XIPERE in a given country, or (iii) ten years from the first commercial sale of XIPERE in a given country. The Company's rights 
to these royalties and milestone payments have been sold pursuant to the terms and conditions of the Purchase and Sale Agreement described in Note 5 to 
the consolidated financial statements.

 In August 2021, the Company entered into an amendment to the Arctic Vision License Agreement to expand the territories covered by the license to 
include India and the ASEAN Countries (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam).  In 
September 2021, the Company entered into a second amendment to the Arctic Vision License Agreement to expand the Arctic Territory to include 
Australia and New Zealand. The Company received an aggregate of $3.0 million in consideration for the expansion of the Arctic Territory.

BioCryst Pharmaceuticals, Inc.

On November 1, 2023, the Company, entered into the BioCryst License Agreement pursuant to which the Company granted BioCryst an exclusive, 
worldwide and sublicensable license to the Company’s SCS Microinjector for the delivery of BioCryst’s proprietary plasma kallikrein inhibitor known as 
avoralstat for the treatment and prevention of DME. 

The Company received an upfront license fee payment of $5.0 million in connection with signing of the BioCryst License Agreement. In addition, 
the Company is eligible to receive up to an additional $30.0 million in clinical and regulatory milestone payments, and up to a total of $47.5 million in a 
series of post-approval sales-based milestone payments based on the achievement of annual global net product sales milestones up to $2.0 billion. Further, 
during the royalty term, BioCryst has also agreed to pay the Company tiered mid-single digit royalties on annual global net product sales, with the highest 
royalty  rate  applied  to  sales  over  $1.5  billion,  subject  to  reductions  in  specified  circumstances. The  Company's  rights  to  these  royalties  and  milestone 
payments  have  been  sold  pursuant  to  the  terms  and  conditions  of  the  Purchase  and  Sale  Agreement  described  in  Note  5  to  the  consolidated  financial 
statements.

BioCryst  will  be  responsible  for  all  development,  regulatory  and  commercialization  activities  for  avoralstat.  The  Company  is  responsible  for 

supplying SCS Microinjectors to meet BioCryst’s reasonable needs.  

The BioCryst License Agreement, unless earlier terminated, will expire (a) on a country-by-country basis upon the expiration of the royalty term in 

such country or (b) in its entirety upon the expiration of all payment obligations of BioCryst under the BioCryst License Agreement in all countries 
pursuant to clause (a). Each party has the right terminate the License Agreement (i) upon a material breach of the BioCryst License Agreement by the other 
party, subject to a specified cure period and specified exceptions, or (ii) if the other party encounters bankruptcy or insolvency. The Company may 
terminate the BioCryst License Agreement if BioCryst or any of its sublicensees (a “Sublicensee”) commences a legal action challenging the validity, 
enforceability or scope of any of the licensed patents, provided that with respect to any such action initiated by a Sublicensee (a “Sublicensee Action), the 
Company may terminate the BioCryst License Agreement if the Sublicensee Action is not terminated within a specified period of time following 
BioCryst’s receipt of written notice from the Company or if BioCryst does not terminate the applicable sublicense, in each case within a specified period of 
time. BioCryst may terminate the BioCryst License Agreement (i) immediately upon written notice to the Company if, after exercising commercially 
reasonable efforts, BioCryst determines in good faith that it is not advisable to continue development or commercialization of avoralstat as a result of a 
material safety issue and (ii) in its entirety or in part on a country-by-country basis, for any or no reason, upon prior written notice to the Company, 
provided that in the event of such a termination, BioCryst shall not, for a period of two years from the date of such a termination, initiate in the territory 
subject to the termination a Phase 3 clinical trial in which avoralstat is administered to the suprachoroidal space using a device other than the SCS 
Microinjector.

Emory and Georgia Tech

On January 31, 2024 (the “Amendment Execution Date”), the Company and the Licensor, entered into the Amendment to the Company’s License 
Agreement  with  Licensor  dated  July  4,  2012  (as  amended,  the  “License  Agreement”),  pursuant  to  which  the  Company  received  a  worldwide  exclusive 
license to specified patents relating to methods and devices for drug delivery using a microinjector.

Pursuant to the Amendment, the parties agreed to reduce the Sublicense Percentage (as defined in the License Agreement) from a low double digit 

percentage to a high single digit percentage that the Company will pay the Licensor applicable to any fees or payments paid to the Company by any 
Sublicensee (as defined in the License Agreement) of the Licensed Patents and/or Licensed Technology (each as defined in the License Agreement), on or 
after July 1, 2023, excluding (i) amounts paid to the Company by a Sublicensee to reimburse the Company for certain research and development costs 
pursuant to a written agreement between the Company and such Sublicensee, (ii) the value of intellectual property transferred or granted to the Company if 
necessary or helpful to the development or commercialization of Licensed Products (as defined in the License Agreement) and (iii) amounts paid for shares 
of the Company’s stock. The payment to Licensor of any such Sublicense Percentage is due within 30 days of receipt by the Company of a qualifying 
payment from a Sublicensee, provided however, with respect to any qualifying payments received by the Company from 

99

Table of Contents

a Sublicensee after July 1, 2023 but prior to January 1, 2025, the payment to Licensor of any such Sublicensee Percentage is due to Licensor by March 31, 
2025. 

In addition, the parties agreed to a revised annual license maintenance fee due each year, or the Maintenance Fee, starting in 2023 through 2028, as 

follows: $250,000 for 2023 through 2025, $350,000 for 2026, $400,000 for 2027 and $500,000 for 2028.  The Company paid the Maintenance Fee for 2023 
in February 2024. The remaining annual Maintenance Fee payments are due on October 1st of each year.

Other

The Company periodically enters into short-term agreements with other customers to evaluate the potential use of its proprietary SCS Microinjector 
with third-party product candidates for the treatment of various diseases. Funds received from these agreements are recognized as revenue over the term of 
the agreement. The Company recorded $50,000, $13,000 and $200,000 of revenue from these agreements during the years ended December 31, 2023, 2022 
and 2021, respectively.

13. Fair Value Measurements

The Company’s material financial instruments at December 31, 2023 and 2022, consisted primarily of cash and cash equivalents. The fair value of 

cash and cash equivalents, other current assets and accounts payable approximate their respective carrying values due to the short-term nature of these 
instruments and are classified as Level 1 in the fair value hierarchy. The fair value of liability related to the sales of future royalties approximates the 
carrying value. 

There were no transfers between Levels 1, 2 and 3 during the years ended December 31, 2023 and 2022.

14. Related Party Transactions

During 2023, a member of the Company's Board of Directors took a position as Chief Executive Officer of a company that is a vendor of the 

Company. As of December 31, 2023, the Company has recorded $331,000 in accounts payable and $215,000 in accrued expense with this vendor in the 
consolidated balance sheets. For the year ended December 31, 2023, the Company has recorded $1.1 million of expense in the consolidated statements of 
operations.

The Chair of the Board of Directors of BioCryst also serves on the Company’s Board of Directors. For the year ended December 31, 2023, there was 

$5.0 million related to the License Agreement recorded in license and other revenue in the consolidated statements of operations.

15. Net (Loss) Income Per Share

Basic net (loss) income per share is calculated by dividing the net (loss) income by the weighted average number of shares of common stock 

outstanding for the period, without consideration of the dilutive effect of potential common stock equivalents. Diluted net (loss) income per share gives 
effect to all dilutive potential shares of common stock outstanding during this period.

For periods in which the Company incurred net losses, common stock equivalents were excluded which included stock options, unvested restricted 

stock and stock purchase warrants, have been excluded from the computation of diluted net loss per share as their inclusion would have the effect of 
reducing the net loss per share. Therefore, the denominator used to calculate both basic and diluted net loss per share is the same in all periods presented.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended 

(the “Exchange Act”), refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports 
that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and 
forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and 
communicated to a company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions 
regarding required disclosure.

In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how 

well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. 
Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit 
relationship of possible disclosure controls and procedures. The design of any system of controls also is based in part upon certain assumptions about the 
likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; 
over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. 
Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure 

controls and procedures as of December 31, 2023. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our 
disclosure controls and procedures were effective as of the end of the period covered by this report at the reasonable assurance level.

Changes in Internal Controls over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2023 that has materially affected, 

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

Management’s Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm 

Our management is responsible for establishing and maintaining an adequate system of internal control over financial reporting, as defined in the 

Exchange Act Rule 13a-15(f). Management conducted an assessment of our internal control over financial reporting based on the framework established in 
2013 by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on the assessment, 
management concluded that, as of December 31, 2023, our internal control over financial reporting was effective. 

This Annual Report does not include an attestation report of our registered public accounting firm regarding internal control over financial reporting 

as required by Section 404(c) of the Sarbanes Oxley Act of 2002. Because we qualify as a non-accelerated filer and a smaller reporting company under 
SEC rules, management's report was not subject to attestation by our independent registered public accounting firm.

3.3  Governance.

(a)  Alliance  Managers .  Each  Party  will  appoint  an  individual  to  act  as  its  alliance  manager  under  this 
Agreement as soon as practicable after the Effective Date (each an “Alliance Manager”). The Alliance Managers will: (i) serve 
as the primary points of contact between the Parties for the purpose of providing the other Party with information on the progress 
of a Party’s activities under this Agreement; (ii) be responsible for facilitating the flow of information and otherwise promoting 
communication,  coordination,  and  collaboration  between  the  Parties  with  respect  to  the  status,  progress  and  results  of  the 
Development, Commercialization or other Exploitation of the Covered Product under the Agreement; (iii) facilitate the prompt 
resolution  of  any  disputes;  and  (iv)  perform  such  other  functions  as  expressly  set  forth  in  this  Agreement  or  allocated  to  the 
Alliance  Managers  by  the  Parties’  written  agreement.  An  Alliance  Manager  may  also  bring  any  matter  to  the  attention  of  the 
executive  officers  and  other  personnel  as  appropriate  if  such  Alliance  Manager  reasonably  believes  that  such  matter  warrants 
such  attention.  Each  Party  will  use  reasonable  efforts  to  keep  an  appropriate  level  of  continuity  but  may  replace  its  Alliance 
Manager at any time upon written notice to the other Party.

(b)  Meetings. During the Term and until the initiation of a Phase III Clinical Trial for the Covered Product, the

BioCryst  to  present  and  share  any  updates  and  progress  regarding  the  Exploitation  of  the  Covered  Product  during  such 
immediately preceding Calendar Year (or such other period as mutually agreed by the Parties). Such meetings may be held in 
person,  by  audio  or  video  conference.  The  Alliance  Managers  will  be  responsible  for  calling  meetings  and  preparing  and 
circulating an agenda to the Parties’ respective executive officers in advance of each meeting.

(c)  Decisions.  Notwithstanding  any  provision  to  the  contrary  set  forth  in  this  Agreement,  without  the  other 
Party’s  prior  written  consent,  no  decision  of  the  Alliance  Managers  may:  (i)  result  in  a  material  increase  in  the  other  Party’s 
obligations, costs, or expenses under this Agreement, unless, in each case, such actions are reasonably necessary for each Party to 
comply with Applicable Law or as the owner and holder of any Regulatory Approval, as applicable, for the Covered Product; (ii) 
take or decline to take any action that would be reasonably likely to result in a violation of any Applicable Law, the requirements 
of any Regulatory Authority, or any agreement with any Third Party or would be reasonably likely to result in the infringement or 
misappropriation of Intellectual Property rights of any Third Party; or (iii) amend, modify, or conflict with this Agreement, any 
Quality Agreement, the Pharmacovigilance Agreement, the

2.1 (License Grant) and Article 4 (Manufacture and Supply of Clearside Devices), the Covered Product in the Field and in the 
Territory  at  its  sole  cost  and  expense.  Without  limiting  the  obligations  set  forth  in  Section  3.1  (Diligence),  Clearside  further 
acknowledges  that  BioCryst  is  in  the  business  of  Exploiting  pharmaceutical  products  and  nothing  in  this  Agreement  will  be 
construed as restricting such business or imposing on BioCryst the duty to Exploit the Covered Product to the exclusion of, or in 
preference to, any other product or in any way other than in accordance with its normal commercial practices. 

3.5  Booking  of  Sales;  Distribution .  As  between  the  Parties,  BioCryst  will  have  the  sole  right  to  invoice  and  book 
sales,  establish  all  terms  of  sale  (including  pricing  and  discounts)  and  warehouse  and  distribute  the  Covered  Product  in  the 
Territory  and  perform  or  cause  to  be  performed  all  related  services.  Subject  to  Section  3.2(b)  (Recalls,  Suspensions  or 
Withdrawals),  as  between  the  Parties,  BioCryst  will  handle  all  returns,  recalls  or  withdrawals,  order  processing,  invoicing, 
collection, distribution and inventory management with respect to Covered Product in the Territory.

3.6  Progress  Reports .  Until  the  Covered  Product  receives  its  first  Regulatory  Approval  anywhere  in  the  Territory, 
BioCryst  shall  provide  Clearside  semi-annual  reports  summarizing  its  and  its  Affiliates’  and  Sublicensees’  significant 
Development and Commercialization activities with respect to the Covered Product, including a summary of the data, timelines 
and  results  of  such  Development  and  any  planned  Commercialization  activities,  and  good  faith,  non-binding  estimates  of  the 
timing  of  completion  of  the  milestone  events  set  forth  in  Section  5.2  (Development  and  Regulatory  Milestone  Payments). 
BioCryst shall provide reports to Clearside at least [***] every [***] ([***]) months, or such other frequency as mutually agreed 
by  the  Parties.  All  reports  provided  by  BioCryst  under  this  Section  3.6  (Progress  Reports)  will  be  BioCryst’s  Confidential 
Information, subject to the terms of Article 7 (Confidentiality). 

ARTICLE 4
MANUFACTURE AND SUPPLY OF CLEARSIDE DEVICES

4.1  General Obligation; Continuity of Supply.

(a)  General Obligations. Clearside will (directly or through a Third Party supplier) Manufacture and supply 
all  of  BioCryst’s  requirements  of  the  Clearside  Devices  for  use  with  the  Covered  Product  pursuant  to  this  Agreement  and  the 
Commercial Supply Agreement. 

(b)  Existing  Supply .  Clearside  currently  obtains  the  Clearside  Devices  from  one  or  more  contract 
manufacturing organizations (the “Existing Suppliers”). Clearside will ensure: (i) material compliance at all times with the terms 
of its agreements with the Existing Suppliers (the “Existing Supply Agreements”); (ii) that any Clearside failure to comply with 
an 

20

 
 
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE 
IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

Existing Supply Agreement does not materially adversely impact BioCryst; and (iii) that such Existing Supply Agreements are 
not terminated unless and until either (A) BioCryst has entered into its own agreement with any Existing Supplier for supply of 
the Clearside Devices or (B) Clearside has established and qualified another supplier for the Clearside Devices. In the event of a 
Supply Failure (as defined below), upon BioCryst’s reasonable request, Clearside will facilitate negotiations between the Existing 
Supplier and BioCryst with respect to an agreement for supply of the Clearside Devices.

4.2  Preclinical and Clinical Manufacture and Supply of Clearside Devices.

(a)  Development Orders. 

(i)  Clearside  will  supply  all  Clearside  Devices  reasonably  needed  by  BioCryst  for  Development  of 
the  Covered  Product  in  accordance  with  the  specifications  attached  hereto  as  Exhibit  4.2  (CLEARSIDE  DEVICE  SPECIFICATIONS) 
(“Clearside Device Specifications”), including all Clearside Devices reasonably needed for clinical trials or otherwise as needed 
to  apply  for,  seek,  obtain  and  maintain  any  Regulatory  Approval  for  the  Covered  Product  or  the  use  of  a  Clearside  Device  in 
connection with the Covered Product. The Parties will agree upon and approve in writing a Quality Agreement that will apply
with  respect  to  the  Manufacture  of  such  Clearside  Devices.  Clearside  represents,  warrants  and  covenants  that  all  Clearside 
Devices supplied by Clearside shall be Manufactured and supplied in accordance with the Clearside Device Specifications and 
the applicable Quality Agreement. BioCryst will not, and will not permit its Affiliates, Sublicensees, Distributors and Third-Party 
Manufacturers to, modify or alter a Clearside Device without Clearside’s prior written consent. Any modification or alteration of 
a Clearside Device by Clearside on behalf of BioCryst will be at BioCryst’s sole cost and expense (other than costs and expenses 
up to [***] Dollars ($[***]) in the aggregate, which shall be borne solely by Clearside) pursuant to a separate services agreement 
to be agreed by the Parties; provided, that Clearside will be under no obligation to modify or alter a Clearside Device unless such 
modification or alteration is required to comply with (A) Applicable Law, (B) a request from a Regulatory Authority, or (C) the 
Clearside  Device  Specifications,  Quality  Agreement,  or  Commercial  Supply  Agreement,  as  applicable,  in  accordance  with 
Section 4.2(c) (Shipment; Risk of Loss).

(ii)  BioCryst may place orders for Clearside Devices needed for Development of the Covered Product 
(a “Development Order”) at least [***] ([***]) days prior to the requested delivery date, and, provided Development Orders are 
placed within such time period, Clearside will deliver such Clearside Devices within such time period. Within [***] ([***]) days 
after  the  Effective  Date,  BioCryst  will  provide  to  Clearside  an  initial  non-binding  [***]  ([***])-month  rolling  forecast  of 
Development Orders (the “Forecast”). Thereafter, BioCryst will provide an updated Forecast for the subsequent [***] ([***])-
month  period  no  later  than  the  [***]  ([***])  Business  Day  of  each  subsequent  Calendar  Half.  Notwithstanding  the  foregoing, 
Clearside will use Commercially Reasonable Efforts to ensure that it, the Existing Suppliers, or any other supplier qualified in 
accordance  with  this  Agreement  has  at  all  times  sufficient  manufacturing  capacity  to  satisfy  all  Development  Orders  in  the 
timelines set forth herein.

21

 
 
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE 
IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

BioCryst shall pay such invoice in accordance with Section 5.6 (Invoices).

(b)  Pricing; Payment.  Clearside  will  invoice  BioCryst  for  the  Clearside  Devices  at  the  Transfer  Price,  and 

(c)  Shipment; Risk of Loss.  Clearside shall package and ship the Clearside Devices in a manner consistent 
with  BioCryst’s  reasonable  instructions  and  in  compliance  with  the  terms  and  conditions  of  this  Agreement,  any  applicable 
Quality  Agreement,  and  any  Development  Order,  as  applicable.  Clearside  shall  deliver  all  Clearside  Devices  DDP  (Incoterms 
2020) to BioCryst’s designated location.

(d)  Safety Stock.  Clearside  will  use  Commercially  Reasonable  Efforts  to  purchase  and  store  (at  BioCryst’s 
expense as set forth below) safety stock of excess Clearside Devices of at least [***] ([***]) months’ supply of Clearside Devices 
pursuant  to  BioCryst’s  most  recent  Forecast  (the  “Safety  Stock”).  BioCryst’s  price  for  the  Safety  Stock  (the  “Safety  Stock 
Price”) will be equal to [***]. Clearside will invoice BioCryst for Safety Stock at the Safety Stock Price, and BioCryst shall pay 
such invoice in accordance  with  Section 5.6 (Invoices)].  Title  to  the  Safety  Stock  will  pass  to  BioCryst  upon  delivery  of  such 
Safety Stock to BioCryst or its designee in accordance with Section 4.2(c) (Shipment;  Risk  of  Loss).  Clearside  will  maintain  a 
regular  rotation  of  such  Safety  Stock  as  necessary  to  avoid  expiration  or  other  spoilage.  Clearside  shall  provide  an  update 
regarding  its  current  Safety  Stock  of  Clearside  Devices  upon  BioCryst’s  request.  Notwithstanding  anything  to  the  contrary  set 
forth  in  this  Agreement  or  the  Commercial  Supply  Agreement,  Clearside  may  only  use  Safety  Stock  to  fill  any  shortfall  in 
quantities of Clearside Devices ordered by BioCryst that Clearside is unable to supply despite Commercially Reasonable Efforts 
after obtaining BioCryst’s express written consent (not to be unreasonably withheld, conditioned or delayed), in which case the 
used Safety Stock will be replaced as soon as possible. For clarity, Safety Stock may not be used for any other purpose. BioCryst 
will have the right to inspect Safety Stock in the location it is held at reasonable times and upon reasonable prior written notice to 
Clearside.  From  time  to  time,  BioCryst  and  Clearside  may  review  Safety  Stock  levels  required  to  be  maintained  under  this 
Section 4.2(d) (Safety Stock) and make mutually agreeable adjustments.

(e)  Supply Failure.

Commercial  Supply  Agreement,  Clearside  fails  to  supply  BioCryst  with  Clearside  Devices  that  meet  the  Clearside  Device 
Specifications  and  that  are  not  otherwise  damaged  or  defective,  in  quantities  that  are  at  least  [***]  percent  ([***]%)  of  the 
quantities of Clearside Devices that Clearside is obligated to supply [***], on at least [***] ([***]) occasions in any consecutive
[***]  ([***])  month  period,  for  any  reason  other  than  due  to  the  material  breach  by  BioCryst  of  this  Agreement  (a  “Supply 
Failure”),  BioCryst  may,  at  its  sole  discretion,  upon  not  less  than  [***]  ([***])  days  written  notice  to  Clearside  (a  “Supply 
Failure Notice”): (A) require Clearside to supply the undelivered Clearside Devices at a future date to be agreed upon by the 
Parties;  or  (B)  elect  to  have  one  or  more  Third  Parties  identified  by  BioCryst  (each,  a  “Third  Party  Manufacturer”) 
Manufacture Clearside Devices (an “Alternative Manufacturer Election”), in which case BioCryst will require its Third Party
Manufacturer(s) to only

Manufacture and sell such Clearside Devices for BioCryst’s and its Affiliates’, Distributors’, and Sublicensees’ Exploitation in 
connection with the Covered Product within the scope of the licenses set forth in Section 2.1 (License Grant).

(ii)  Upon  the  occurrence  of  a  Supply  Failure  and  an  Alternative  Manufacturer  Election  and  at 
Clearside’s expense: (A) BioCryst (or its designated Third Party Manufacturer(s)) will have the right to Manufacture Clearside 
Devices  within  the  scope  of  the  license  under  Section  2.1  (License  Grant),  and  (B)  Clearside  shall  transfer  the  Clearside 
Manufacturing Know-How to BioCryst and any Third Party Manufacturers identified by BioCryst as specified in the following 
sentence. Clearside shall promptly (x) disclose to BioCryst and any such Third Party Manufacturer all Clearside Manufacturing 
Know-How; (y) provide BioCryst or any such Third Party Manufacturer with the training, documentation and other information 
Controlled by Clearside and relating to the use of the Manufacturing process as may be necessary for BioCryst and such Third 
Party Manufacturers to Manufacture Clearside Devices; and (z) make appropriately trained personnel available for consultation 
and  advice  upon  BioCryst’s  reasonable  request  to  the  extent  reasonably  necessary  to  provide  technical  assistance  necessary  to 
enable BioCryst or such Third Party Manufacturers to Manufacture Clearside Devices.

(f)  Restricted Use of Clearside Devices. Any Clearside Devices supplied to BioCryst under a Development 
Order  that  are  not  used  for  Development  of  the  Covered  Product  shall,  at  Clearside’s  election  following  BioCryst’s  written 
confirmation that it is no longer Developing the Covered Product, be returned to Clearside or destroyed by BioCryst. For clarity, 
no Clearside Device supplied to BioCryst under a Development Order may be used by BioCryst for any Commercial purposes.

4.3  Commercial Manufacture and Supply of Clearside Devices. At an appropriate time during Development of the 
Covered Product and in any event prior to the initiation of a Phase III Clinical Trial for the Covered Product, the Parties, together 
with the Existing Suppliers or any other supplier qualified in accordance with this Agreement, will negotiate in good faith and 
enter  into  an  agreement  for  commercial  supply  of  the  Clearside  Devices  (“Commercial  Supply  Agreement”)  and  a  Quality 
Agreement. The Commercial Supply Agreement will provide for supply of the Clearside Devices at the Transfer Price, and the 
Commercial Supply Agreement and Quality Agreement will otherwise contain mutually agreed terms and conditions consistent 
with this Agreement, including Article 4 (Manufacture and Supply of Clearside Devices) and any definitions of terms embodied 
therein, in addition to other terms that are reasonable and customary, including provisions to ensure quality and audit by or on 
behalf of BioCryst. For clarity, notwithstanding the negotiation of the Commercial Supply Agreement prior to initiation of the 
Phase  III  Clinical  Trial  for  the  Covered  Product,  any  Clearside  Devices  Manufactured  and  supplied  for  use  in  the  Phase  III 
Clinical Trial or any Phase IV Clinical Trial will be Manufactured and supplied pursuant to Section 4.2 (Preclinical and Clinical 
Manufacture and Supply of Clearside Devices), not the Commercial Supply Agreement.

4.4  GMP .  The  Parties  or  their  Affiliates  will  execute,  as  reasonably  requested  by  BioCryst,  agreements,  such  as  a 
Quality Agreement, necessary or useful to ensure that all Clearside Devices and their intermediates and manufacturing facilities

(2)  No  Valid  Claims  of  Clearside  Patent  Rights  or  Covered  Product  Patent  Rights .  If, 
during the Royalty Term for the Covered Product in a country, no Valid Claim of the Clearside Patent Rights or Covered Product 
Patent Rights exists that Covers the Covered Product in such country, then the applicable royalty rates that would otherwise be 
payable under Section 5.4(a) (Royalty Rates) shall be reduced by [***] percent ([***]%) during the period of the Royalty Term in 
which no such Valid Claim of the Clearside Patent Rights or Covered Product Patent Rights exists.

(iii)   Generic Competition During the Royalty Term. On a country-by-country basis, if at any time 
during the Royalty Term a Generic Product is sold in such country and the aggregate Net Sales of the Covered Product in such 
country in any Calendar Quarter thereafter are at least [***] percent ([***]%) lower as compared to the average quarterly Net 
Sales of the Covered Product in such country [***] immediately preceding the Calendar Quarter in which the Generic Product 
was  first  sold,  then,  following  such  reduction  in  Net  Sales,  the  Net  Sales  of  the  Covered  Product  in  such  country  used  for 
calculation of royalties pursuant to Section 5.4 (Royalties) shall be reduced by [***] percent ([***]%).

(iv)  [***] Floor.  In  no  event  shall  (A)  the  application  of  Section 5.4(b)(i)  (Third-Party  IP),  Section 
5.4(b)(ii) (No Valid Claims) or Section 5.4(b)(iii) (Generic Competition During the Royalty Term) reduce the royalty payable on 
Net Sales of the Covered Product in a country in a Calendar Quarter during the Royalty Term to less than [***] percent ([***]%) 
of the royalty that would be payable on Net Sales of the Covered Product in such country determined in accordance with Section 
5.4(a) (Royalty Rates) without application of any such reductions or [***]. [***]. 

5.5  Royalty Payments and Reports. BioCryst will calculate all amounts payable to Clearside pursuant to Section 5.4 
(Royalties)  at  the  end  of  each  Calendar  Quarter,  which  amounts  will  be  converted  to  Dollars,  in  accordance  with  Section  5.7 
(Currency; Payment Instructions; Late Payments; Offsets). BioCryst will report to Clearside the royalty amounts due with respect 
to a given Calendar Quarter within [***] ([***]) days after the end of such Calendar Quarter. Thereafter, Clearside will invoice 
BioCryst within [***] ([***]) days of Clearside’s receipt of such quarterly royalty report for the royalty amounts due for such 
Calendar Quarter and BioCryst’s payment of such royalty amounts due for such Calendar Quarter shall proceed in accordance 
with Section 5.6 (Invoices).  Each  quarterly  royalty  report  shall  include  a  statement  of  the  amount  of  Net  Sales  and  number  of 
units  of  the  Covered  Product  in  each  country  in  the  Territory  during  the  applicable  Calendar  Quarter  (including  such  amounts 
expressed  in  local  currency  and  as  converted  to  Dollars)  and  a  calculation  of  the  amount  of  royalty  payment  due  on  such  Net 
Sales  for  such  Calendar  Quarter,  which  calculation  shall  include  the  itemized  deductions  for  the  Covered  Product  for  each 
country included in the calculation of Net Sales. BioCryst will also include in such reports any additional information reasonably 
requested by Clearside to calculate Net Sales attributable to its Affiliates and Sublicensees.

5.6  Invoices .  If  either  Party  (the  “Invoicing  Party”)  is  owed  amounts  by  the  other  Party  (the  “Invoiced  Party”) 
pursuant  to  this  Agreement,  the  Invoicing  Party  must  invoice  the  Invoiced  Party  for  such  amounts  within  any  applicable  time 
periods set forth in this Agreement. Except as otherwise set forth in Section 5.1 (Upfront Fee),  the  Invoiced  Party  will  pay  all 
undisputed amounts in such invoices within [***] ([***]) days of receipt. In the event the Invoiced Party disputes any portion of 
an invoice, it shall notify the Invoicing Party in writing within [***] ([***]) days after receipt of invoice. The Parties shall use 
good faith efforts to resolve such dispute.

5.7  Currency; Payment Instructions; Late Payments; Offsets. All amounts payable and calculations hereunder will 
be  in  Dollars,  and  all  payments  due  under  this  Agreement  will  be  made  by  wire  transfer  in  immediately  available  funds  to  an 
account designated by Clearside in

advance  of  such  payment,  or  by  other  mutually  acceptable  means.  For  the  purpose  of  calculating  any  sums  due  under,  or 
otherwise  reimbursable  pursuant  to,  this  Agreement  (including  the  calculation  of  Net  Sales  expressed  in  currencies  other  than 
Dollars),  a  Party  will  convert  any  amount  expressed  in  a  foreign  currency  into  Dollar  equivalents  using  its,  its  Affiliate’s  or 
Sublicensee’s standard conversion methodology consistent with Accounting Standards. If any payment due to either Party under 
this  Agreement  is  not  paid  when  due,  then  such  paying  Party  will  pay  interest  thereon  (before  and  after  any  judgment)  at  an 
annual rate (but with interest accruing on a daily basis) of [***] ([***]) basis points above the U.S. effective federal funds rate, as 
adjusted  each  Business  Day  and  published  by 
its  website 
(https://apps.newyorkfed.org/markets/autorates/fed%20funds)  (or  in  the  event  that  the  U.S.  effective  federal  funds  rate  is  no 
longer an applicable reference rate, such reasonably equivalent alternative as may be selected by mutual agreement exercising 
reasonable discretion), such interest to run from the date on which payment of such sum became due until payment thereof in full 
together with such interest; provided,  that,  with  respect  to  any  disputed  payments,  no  interest  payment  shall  be  due  until  such 
dispute is resolved and the interest which shall be payable thereon shall be based on the finally-resolved amount of such payment. 
Notwithstanding the previous sentence, the total payable interest rate will never be less than [***] ([***]) basis points. BioCryst 
shall have the right, upon prior written notice to Clearside, to offset any undisputed payment, resolved payment or payment that is 
the subject of a pending dispute that is owed by Clearside but not timely paid against any payments owed by BioCryst, if any, 
under this Agreement.

5.8  Taxes.

(a)  General.  The  milestones,  royalties  and  other  amounts  payable  by  BioCryst  to  Clearside  pursuant  to  this 
Agreement (each, a “Payment”) will be paid free and clear of any and all taxes, except for any withholding taxes required by 
Applicable Law. Except as provided in this Section 5.8 (Taxes), Clearside will be solely responsible for paying any and all taxes 
(other than withholding taxes required by Applicable Law to be deducted from Payments and remitted by BioCryst) levied on 
account of, or measured in whole or in part by reference to, any Payments it receives. BioCryst will deduct or withhold from the 
Payments any taxes that it is required by Applicable Law to deduct or withhold. Notwithstanding the foregoing, if Clearside is 
entitled under any applicable tax treaty to a reduction of rate of, or the elimination of, applicable withholding tax, it may deliver 
to  BioCryst  or  the  appropriate  governmental  authority  (with  the  assistance  of  BioCryst  to  the  extent  that  this  is  reasonably 
required and is expressly requested in writing) the prescribed forms necessary to reduce the applicable rate of withholding or to 
relieve BioCryst of its obligation to withhold such tax and BioCryst will apply the reduced rate of withholding or dispense with 
withholding, as the case may be; provided that BioCryst has received evidence, in a form reasonably satisfactory to BioCryst, of 
Clearside’s delivery of all applicable forms (and, if necessary, its receipt of appropriate governmental authorization) at least [***] 
([***]) days prior to the time that the Payments are due. If, in accordance with the foregoing, BioCryst withholds any amount, it 
will pay to Clearside the balance when due, make timely payment to the proper taxing authority of the withheld amount and send 
to Clearside proof of such payment within [***] ([***]) days following such payment.

(a)  BioCryst. Upon Clearside’s reasonable request, BioCryst will, and will cause its Affiliates and its and their 
Sublicensees  to,  permit  an  independent,  nationally  recognized  accounting  firm  designated  by  Clearside  and  acceptable  to 
BioCryst, at reasonable times and upon at least [***] ([***]) days’ notice, to audit the books and records maintained pursuant to 
Section 5.9(a)  (Financial  Records—BioCryst)  to  ensure  the  accuracy  of  all  reports  and  payments  under  this  Agreement.  Such 
examinations may not be conducted more than [***] in any [***] ([***]) month period and are limited to the preceding [***] 
([***]) month period. No record may be audited more than once. The cost of this audit will be borne by Clearside, unless the 
audit reveals a variance of more than [***] percent ([***]%) from the reported amounts, in which case BioCryst will reimburse 
Clearside for the accounting firm’s fees in performing the audit. If such audit concludes that (a) additional amounts were owed by 
BioCryst, BioCryst will pay the additional amounts or (b) excess payments were made by BioCryst, Clearside will reimburse or 
credit such excess payments, in either case ((a) or (b)), within [***] ([***]) days after the date on which such audit is completed.

(b)  Clearside. Upon BioCryst’s reasonable request, Clearside will, and will cause its Affiliates, and will use

BioCryst will pay the additional amounts or (b) excess payments were made by BioCryst, Clearside will reimburse or credit such 
excess payments, in either case ((a) or (b)), within [***] ([***]) days after the date on which such audit is completed.

5.11 Audit  Dispute .  In  the  event  of  a  dispute  with  respect  to  any  audit  under  Section  5.10  (Audit),  Clearside  and 
BioCryst shall work in good faith to resolve the disagreement. If the Parties are unable to reach a mutually acceptable resolution 
of any such dispute within [***] ([***]) days, the dispute shall be submitted for resolution to a certified public accounting firm 
jointly  selected  by  each  Party’s  certified  public  accountants  or  to  such  other  Person  as  the  Parties  shall  mutually  agree  (the 
“Audit Arbitrator”). The decision of the Audit Arbitrator shall be final and the costs of such arbitration as well as the initial 
audit shall be borne between the Parties in such manner as the Audit Arbitrator shall determine. Not later than [***] ([***]) days

ARTICLE 6
PATENT MATTERS; OWNERSHIP OF INTELLECTUAL PROPERTY

6.1  Filing, Prosecution and Maintenance of Patent Rights. [***.]

(a)  Clearside  Patent  Rights  and  [***] .  Clearside  has  the  first  right,  at  its  discretion  and  using  counsel  it 
selects, to Prosecute and Maintain all Clearside Patent Rights and [***] in Clearside’s name in the Territory and Clearside will be 
solely responsible for all costs and expenses incurred in connection with such Prosecution and Maintenance. Clearside shall: (i) 
provide BioCryst with copies of all filings and formal correspondences relating to [***] to and from the United States Patent and 
Trademark Office and any other patent office (including copies of each patent application, office action, response to office action, 
request for terminal disclaimer, and request for reissue or reexamination of any patent or patent application); (ii) keep BioCryst 
advised of the status of actual and prospective patent filings; (iii) give BioCryst the opportunity to provide and will reasonably 
consider in good faith comments on the Prosecution and Maintenance of the [***]; (iv) reasonably consult with BioCryst prior to 
electing  not  to  continue  to  Prosecute  and  Maintain  any  [***];  (v)  not  make  any  decision  regarding  the  Prosecution  and 
Maintenance of such [***] that materially disadvantages BioCryst as compared to any other licensee of such Patent Rights; and 
(vi)  upon  BioCryst’s  reasonable  request,  seek  claims  related  to  the  combined  use  of  a  Clearside  Device  for  delivery  of  the 
BioCryst Compound in the Field. Each Party will treat any consultation regarding the Prosecution and Maintenance of the [***],

expenses), as both Parties’ Confidential Information. If Clearside elects not to continue to Prosecute and Maintain any Clearside 
Patent Rights, then: [***].

(b)  BioCryst Patent Rights. 

(i)  Compound Patent Rights. As between the Parties, BioCryst shall have the sole right (but not the 
obligation),  using  counsel  it  selects,  to  Prosecute  and  Maintain  the  Patent  Rights  Covering  the  Compound  IP  (“Compound 
Patent Rights”). BioCryst will be solely responsible for all costs and expenses incurred in connection with such Prosecution and 
Maintenance.

(ii)  [***].

(c)  Joint Patent Rights. With respect to any Patent Rights Covering the Joint Inventions (the “Joint Patent 
Rights”),  the Parties shall meet  to  determine  in  what  countries,  if  any,  Joint  Patent  Rights should be filed and the appropriate 
filing  Party  for  such  Joint  Patent  Rights.  The  Parties  shall  equally  share  costs  incurred  by  the  Party  filing  such  Joint  Patent 
Rights. If a Party elects not to equally share costs related to any Joint Patent Right, the other Party shall provide written notice 
upon the decision to not share any Joint Patent Right costs and the Party not giving such notice shall have the right to assume 
responsibility for such Prosecution and Maintenance, at its own sole expense. 

(d)  Claim  Separation .  The  Parties  shall  use  commercially  reasonable  efforts  (including,  as  appropriate,  by 
Prosecuting and Maintaining separate continuation applications, continuation-in-part applications, or divisional applications), in 
each case, as reasonably determined based on then-available scientific or other evidence, to segregate into separate Patents claims 
that would cause a Patent to constitute: (a) a Compound Patent; (b) a Covered Product Patent Right; (c) a Clearside Patent Right; 
(d) [***]; and (e) a Joint Patent Right. 

6.2  Enforcement and Defense of Patent Rights. [***] 

(a)  Notification. In the event that either Party becomes aware of any (i) actual or threatened infringement or 
(ii) alleged or threatened assertion of invalidity or unenforceability, in each case ((i) and (ii)), of any Compound Patent Right, 
Covered Product Patent Right, Joint Patent Right, Clearside Patent Right or [***] in the Territory by a Third Party, such Party 
will  promptly  notify  the  other  Party  in  writing  and  will  provide  any  information  available  to  such  Party  relating  to  such 
infringement or assertion of invalidity or unenforceability.

(b)  Compound  Patent  Rights .  As  between  the  Parties,  BioCryst  shall  have  the  sole  right  (but  not  the 
obligation), using counsel it selects, to enforce or defend the Compound Patent Rights. BioCryst will be solely responsible for all 
costs and expenses incurred in connection with such enforcement.

(c)  Covered  Product  Patent  Rights .  BioCryst  shall  have  the  first  right  but  not  the  obligation,  at  its  own 
expense, to enforce or defend the Covered Product Patent Rights in the Territory. BioCryst will notify Clearside of its election 
within [***] ([***]) days after notification

of  such  Covered  Product  Patent  Right  infringement  or  assertion  of  invalidity  or  unenforceability  pursuant  to  Section  6.2(a) 
(Notification). If BioCryst elects not to pursue or defend against such action, Clearside will have the right, but not the obligation, 
at its own expense, to commence a suit or take action relating to such infringement or defend the validity or enforceability of the 
Covered Product Patent Rights in any claim, suit, or proceeding in the Territory. The Party not bringing or defending against an 
action with respect to the Covered Product Patent Right will be entitled to separate representation in such matter by counsel of its 
own  choice  and  at  its  own  expense,  but  such  Party  will  at  all  times  cooperate  fully  with  the  enforcing  or  defending  Party. 
Additionally,  the  Party  not  bringing  or  defending  against  an  action  under  the  Covered  Product  Patent  Right  may  have  an
opportunity to participate in such action, at its sole cost and expense, to the extent that the Parties may mutually agree at the time 
the  enforcing  or  defending  Party  elects  to  bring  or  defend  against  such  action  hereunder  and,  whether  or  not  the  Party  not 
bringing  or  defending  against  the  action  elects  to  participate,  the  Party  bringing  or  defending  against  the  action  will  provide 
regular updates on the status of the action to the Party not bringing or defending against the action. 

(d)  Joint  Patent  Rights .  The  Parties  shall  mutually  determine  whether  (i)  to  take  action  to  obtain  a 
discontinuance  of  infringement  or  bring  suit  against  a  Third  Party  infringer  or  (ii)  defend  the  validity  or  enforceability  in  any 
claim, suit, or proceeding, in each case ((i) and (ii)), of any Joint Patent Rights within [***] ([***]) days (or earlier as required by 
Applicable Law) from the date of notice, provided that neither Party shall be obligated to join any such action. In the event that 
either Party does not want to join an action as a party to such action, then the Party not seeking to enforce or defend against such 
claims shall have the right to assign the relevant Joint Patent Rights to the other Party, provided that such assignment is solely and 
sufficient for purposes of commencing or maintaining the action or defense. The Party seeking to enforce or defend against such 
claims shall solely bear all of its expenses. The Parties will reasonably cooperate, at the expense of the Party seeking to enforce 
or defend against such claim, in any such suit and shall have the right to consult with the other Party and to participate in and be 
represented by independent counsel in such litigation at its own expense.

(e)  Clearside Patents Rights and [***]. Clearside shall have the first right but not the obligation, at its own 
expense,  to  enforce  or  defend  (as  applicable)  the  Clearside  Patent  Rights  and  [***],  including  in  the  Field,  in  the  Territory. 
Clearside will notify BioCryst of its election within [***] ([***]) days after notification of such Clearside Patent Right or [***] 
infringement or assertion of invalidity or unenforceability pursuant to Section 6.2(a) (Notification). In the case where Clearside 
elects not to pursue or defend against such action: (i)  if  BioCryst  is  the  sole  exclusive  licensee  with  respect  to  such  Clearside 
Patent Rights or [***], BioCryst will have the right, but not the obligation, at its own expense, to commence a suit or take action 
relating to such infringement or defend the validity or enforceability of such Covered Product Patent Rights in any claim, suit, or 
proceeding in the Territory; or (ii) if BioCryst is not the sole exclusive licensee with respect to such Clearside Patent Rights or 
[***],  BioCryst  and  the  other  exclusive  licensees  may  negotiate  in  good  faith  regarding  the  commencement  of  any  suit  or  the 
taking of any action relating to such infringement or the defense of the validity or enforceability of such Covered Product Patent 
Rights in any claim, suit, or proceeding in the Territory. The Party not bringing or defending against an action with respect to the 
Clearside Patent Right or [***] will be entitled to separate representation in such matter by counsel of its own choice and at its 
own expense, but 

32

 
 
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE 
IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

such  Party  will  at  all  times  cooperate  fully  with  the  enforcing  or  defending  Party.  Additionally,  the  Party  not  bringing  or 
defending against an action under the Clearside Patent Rights or [***] may have an opportunity to participate in such action, at 
its sole cost and expense, to the extent that the Parties may mutually agree at the time the enforcing or defending Party elects to 
bring or defend against such action hereunder and, whether or not the Party not bringing or defending against the action elects to 
participate, the Party bringing or defending against the action will provide regular updates on the status of the action to the Party 
not  bringing  or  defending  against  the  action.  Notwithstanding  the  foregoing,  BioCryst  shall  have  the  first  right  (but  not  the 
obligation), at its own expense, to enforce or defend the Clearside Patent Rights [***] to the extent the alleged Clearside Patent 
Right [***] infringement concerns any kallikrein inhibitor administered or delivered through the use of a device for delivery of 
therapeutic agents to the eye other than a Clearside Device.

(f)  Recovery. If the enforcing Party recovers monetary damages (whether by way of settlement or otherwise) 
from any Third Party in a suit or action for infringement of Covered Product Patent Rights pursuant to Section 6.2(c) (Covered 
Product Patent Rights), Joint Patent Rights pursuant to Section 6.2(d) (Joint Patent Rights), or Clearside Patent Rights or [***] 
pursuant to Section 6.2(e) (Clearside Patents and [***]), such recovery will be allocated first to the repayment of out-of-pocket 
costs  and  expenses  of  the  Party(ies)  with  respect  to  the  action  (on  a  pro  rata  basis).  Any  remaining  damages  after  such 
reimbursement is made shall (i) in the case of the Covered Product Patent Rights pursuant to Section 6.2(c)  (Covered  Product 
Patent Rights), [***]; (ii) in the case of Joint Patent Rights pursuant to Section 6.2(d) (Joint Patent Rights), [***]; and (iii) in the 
case of the Clearside Patent Rights or [***] pursuant to Section 6.2(e)(Clearside Patents and [***]), [***].

(g)  In General; Settlement. In any action, suit or proceeding instituted under this Section 6.2  (Enforcement 
and  Defense  of  Patent  Rights),  the  Parties  will  cooperate  with  and  assist  each  other  in  all  reasonable  respects.  Upon  the 
reasonable  request  of  the  Party  initiating  or  defending  against  such  action,  suit  or  proceeding,  the  other  Party  will  join  such 
action,  suit  or  proceeding  if  necessary  to  establish  standing  in  such  action,  suit  or  proceeding,  and  may  be  represented  using 
counsel of its own choice, at such initiating or defending Party’s expense, or assign the right to enforce or defend the patents to 
the  Party  initiating  or  defending  against  such  action.  Neither  Party  will  have  the  right  to  settle  any  action,  suit  or  proceeding 
under this Section 6.2 (Enforcement and Defense of Rights) in a manner that admits the invalidity or unenforceability of the other 
Party’s Patent Rights or imposes on the other Party restrictions or obligations, without the written consent of such other Party 
(which will not be unreasonably withheld, conditioned, or delayed).

6.3  Defense of Third Party Claims.

(a)  Notice .  If  a  Party  becomes  aware  of  any  actual  or  potential  claim  that  the  Exploitation  of  the  Covered 
Product in the Territory infringes or misappropriates the Intellectual Property of any Third Party (a “Third Party Infringement 
Claim”), such Party shall promptly notify the other Party.

(b)  Control  of  Defense .  Subject  to  Article  10  (Limitation  on  Liability,  Indemnification  and  Insurance), 
BioCryst  shall  have  the  first  right,  but  not  the  obligation,  to  defend  and  control  the  defense  of  any  Third-Party  Infringement 
Claim at its own expense using counsel of its own choice. Clearside may participate in any such Third-Party Infringement Claim 
with counsel of its choice at its own expense; provided that BioCryst shall retain control of the defense of such claim, suit, or 
proceeding. Without limiting the foregoing, if BioCryst finds it necessary or desirable for Clearside to join as a party to any such 
action, Clearside shall execute all papers and perform such acts as shall be reasonably required. If BioCryst fails to assume such 
defense within [***] ([***]) months of the first notice under Section 6.3(a) (Notice) with respect thereto (or such shorter period 
as may be required to comply with applicable legal or regulatory deadlines which relate to such claim), Clearside shall thereafter 
have the right (but not the obligation), upon written notice to BioCryst, to defend and dispose of (including through settlement or 
license) such Third Party Infringement Claim; provided, that Clearside may not dispose of such Third Party Infringement Claim 
without BioCryst’s prior written consent (not to be unreasonably withheld, conditioned, or delayed). In any event, the Parties will 
reasonably assist each other and cooperate in any such Third Party Infringement Claim at the other Party’s request and expense. 
Each Party may at its own expense and with its own counsel join any defense initiated or directed by the other Party under this 
Section 6.3(b) (Control of Defense). Each Party will provide the other Party with prompt written notice of the commencement of 
any such Proceeding under this Section 6.3(b) (Control of Defense), and such Party will promptly furnish the other Party with a 
copy of each communication relating to the alleged infringement that is received by such Party.

6.4  Patent Term Extension and Supplementary Protection Certificate. (a) BioCryst shall be responsible for making 
decisions  regarding  patent  term  extensions  for  any  Compound  Patent  Rights  and  Covered  Product  Patent  Rights,  and  (b)  the 
Parties will cooperate regarding patent term extensions for any Joint Patent Rights, [“***”] or Clearside Patent Rights, in each 
case,  Covering  the  Covered  Product,  in  each  case  of  (a)  and  (b),  in  the  Field  and  Territory,  including  the  United  States  with 
respect  to  extensions  pursuant  to  35  U.S.C.  §  156  et.  seq.  and  in  other  jurisdictions  pursuant  to  supplementary  protection 
certificates, and in all jurisdictions with respect to any other extensions that are now or become available in the future, wherever 
applicable.  In  the  event  that  BioCryst  or  the  Parties,  as  applicable,  determine  to  apply  for  any  patent  term  extension  or 
supplementary protection certificate for any Compound Patent Right, Covered Product Patent Right, Joint Patent Right, [***] or 
Clearside Patent Right, in each case Covering the Covered Product in the Field in the Territory, each Party shall provide the other 
Party with prompt and reasonable assistance, as applicable, as is required under any Applicable Law to obtain such extension or 
supplementary protection certificate. 

6.5  Ownership of Intellectual Property.

(a)  Background IP. Subject to the licenses granted by Clearside pursuant to this Agreement, each Party owns 
and will continue to own all Intellectual Property: (i) owned or Controlled by such Party as of the Effective Date, or (ii) that are 
Invented solely by or on behalf of Representatives of such Party or its Affiliates outside the performance of activities under this 
Agreement.  Without  limiting  the  foregoing,  BioCryst  owns  and  will  continue  to  own  all  Intellectual  Property  that  Covers  the 
BioCryst Compound as of the Effective Date.

IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

(b)  Foreground IP. 

(i)  BioCryst Solely-Owned IP. BioCryst shall solely own all Intellectual Property Invented by or on 
behalf of Representatives of a Party or its Affiliates after the Effective Date in the performance of activities under this Agreement 
(“Foreground IP”) that relates solely to [***].

(ii)  Clearside Solely-Owned IP. Clearside shall solely own all Foreground IP that (A) is not Covered 
Product IP or Compound IP, and (B) is related to the use of a Clearside Device alone or in combination with any substance other 
than the BioCryst Compound for use in the Field (“Clearside Inventions”). 

(iii)  Jointly-Owned IP. The Parties shall jointly own all Foreground IP that is not Covered Product IP, 
Compound  IP  or  Clearside  IP  (“Joint  Inventions”).  With  respect  to  Exploitation  of  Joint  Inventions  outside  the  scope  of  the 
license  granted  hereunder,  the  Parties  shall  (A)  first,  negotiate  in  good  faith  for  one  or  both  Parties  to  obtain  ownership  or  an 
exclusive  license  to  the  other  Party’s  interest  in  all  or  a  portion  of  such  Joint  Invention  and  (B)  subject  to  any  transaction 
contemplated by the foregoing clause (A), neither Party shall be permitted to sublicense such Joint Invention without the other 
Party’s prior written consent, not to be unreasonably withheld. For the avoidance of doubt, the BioCryst Patent Application shall 
be deemed a Covered Product Patent Right hereunder and owned solely by BioCryst. 

(iv)  Further  Assurances .  Each  Party  agrees  to  execute  any  and  all  further  instruments,  forms  of 
assignment or other documents, and take such further actions, as the other may reasonably request, in order to give effect to these 
ownership provisions in connection with Covered Product IP, Compound IP, Clearside IP, [***] and Joint IP. If a Clearside Patent 
Right  [***]  issues  that  would  otherwise  constitute  a  Covered  Product  Patent  Right,  Clearside  shall  assign  its  right,  title  and 
interest in and to (or, if unable to do so, shall exclusively license (or sublicense, as applicable)) such Clearside Patent Right or 
[***] to BioCryst and, for purposes of this Agreement thereafter, such assigned Clearside Patent Right or [***] shall be deemed a 
Covered Product Patent Right.

6.6  Patent Listings. BioCryst shall have the sole right to make all filings with Regulatory Authorities in the Territory 
with  respect  to  Compound  IP,  Covered  Product  IP,  Clearside  Patent  Rights  (solely  to  the  extent  such  Clearside  Patent  Rights 
contain one or more Valid Claims Covering the Covered Product), [***] and Joint Patent Rights (solely to the extent such Joint 
Patent Rights contain one or more Valid Claims Covering the Covered Product), as required or allowed (a) in the United States, 
in  the  FDA’s  Orange  Book  (titled  “Approved  Drug  Products  With  Therapeutic  Equivalence  Evaluations”),  and  (b)  outside  the 
United  States,  under  the  national  implementations  of  Article  10.1(a)(iii)  of  Directive  2001/EC/83  or  other  international 
equivalents.  Clearside  shall  (i)  provide  to  BioCryst  all  information,  including  a  correct  and  complete  list  of  Clearside  Patent 
Rights, [***] or Joint Patent Rights containing one or more Valid Claims Covering the Covered Product or otherwise necessary 
or reasonably useful to enable BioCryst to make such filings with Regulatory Authorities in the Territory with respect to such 
Patent Rights, and (ii) cooperate with BioCryst’s reasonable requests in connection therewith,

including meeting any submission deadlines, in each case ((i) and (ii)), to the extent required or permitted by Applicable Law. 

ARTICLE 7
CONFIDENTIALITY

7.1  Protection of Confidential Information. Except to the extent expressly authorized by this Agreement, the Parties 
agree that each Party (the “Receiving Party”) receiving any Confidential Information of the other Party (the “Disclosing Party”) 
will not disclose or disseminate Confidential Information of the Disclosing Party to any Third Party unless expressly permitted 
hereunder,  and  will  not  use  such  Confidential  Information  for  any  purpose  other  than  in  performing  the  Receiving  Party’s 
obligations  or  exercising  the  Receiving  Party’s  rights  hereunder.  In  addition,  the  Receiving  Party  will  take  reasonable  steps  to 
protect the Confidential Information of the Disclosing Party from unauthorized use or disclosure, which steps will be no less than 
those  the  Receiving  Party  takes  to  protect  its  own  confidential  or  proprietary  material  of  a  similar  nature.  The  foregoing 
obligations  will  apply  equally  to  all  copies,  extracts  and  summaries  of  the  Disclosing  Party’s  Confidential  Information.  The 
obligations in this Section 7.1 (Protection of Confidential Information) shall be in full force during the Term and for a period of 
[***] ([***]) years thereafter.

7.2  Certain Permitted Disclosures.

(a)  Disclosure of Confidential Information.

(i)  Disclosure  to  Representatives .  Notwithstanding  the  foregoing  and  subject  to  Section  7.2(a)(ii) 
(Disclosures  under  Applicable  Law),  the  Receiving  Party  may  disclose  Confidential  Information  of  the  Disclosing  Party  to 
officers, directors, employees, consultants, subcontractors, contractors, or agents of the Receiving Party or its Affiliates or, in the 
case  of  BioCryst,  its  Sublicensees  and  Distributors,  advisory  board  members  and  collaboration  and  financial  partners 
(collectively, “Representatives”) who have a need to know such Confidential Information in connection with the performance of 
the  Receiving  Party’s  obligations  or  the  exercise  of  the  Receiving  Party’s  rights  under  this  Agreement;  provided  that  such 
Representative is bound by a confidentiality agreement with such Receiving Party that contains terms substantially similar to this 
Article 7 (Confidentiality).

(ii)  Disclosures  under  Applicable  Law .  Notwithstanding  the  foregoing,  each  Party  may  disclose 
Confidential Information of the other Party to a Third Party to the extent such disclosure is reasonably necessary to Prosecute and
Maintain  Patent  Rights  (consistent  with  all  other  limitations  set  forth  in  this  Agreement),  prepare  submissions  to  Regulatory 
Authorities,  prosecute  or  defend  litigation,  comply  with  Applicable  Law  or  submit  information  to  Governmental  Authorities 
(provided that such Third Party, if not a governmental entity, enters into a confidentiality agreement with such Party that contains 
terms no less restrictive than this Article 7 (Confidentiality)), or to the extent necessary to pursue a legal proceeding pursuant to 
Section 5.11 (Audit Dispute), Section 9.2(e) (Alternative Remedy) or Section 11.11 (Dispute Resolution) (including a proceeding 
to enforce or challenge an arbitration award); 

36

 
 
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE 
IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

provided, however, that if a Party intends to make any such disclosure of the Disclosing Party’s Confidential Information, to the 
extent  it  may  legally  do  so  it  will  give  reasonable  advance  notice  to  the  Disclosing  Party  of  such  disclosure  to  permit  the 
Disclosing  Party  to  use  its  reasonable  endeavors  to  secure  confidential  treatment  of  such  Confidential  Information  prior  to 
disclosure (whether through protective orders or otherwise).

(b)  Disclosure of Agreement Terms to Certain Third Parties. The Parties may disclose only the terms or 
conditions of this Agreement (but not any Confidential Information of the other Party) on a need-to-know basis: (i) to its legal 
and financial advisors to the extent such disclosure is reasonably necessary in connection with such Party’s activities as expressly 
permitted by this Agreement; and (ii) to a Third Party in connection with (A) an actual or potential equity investment in or by, or 
underwriting  by,  such  Third  Party,  (B)  an  actual  or  potential  merger,  consolidation  or  similar  transaction  involving  such  Third 
Party, (C) the sale or potential sale of all or substantially all of the assets of the Party or substantially all of the assets related to 
this Agreement to such Third Party or (D) a potential or actual sublicensee hereunder; provided that such Party will make such 
disclosure  only  under  appropriate  conditions  of  confidentiality  by  the  Third  Party  of  confidentiality  and  non-use  at  least 
equivalent in scope to those set forth in this Article 7 (Confidentiality).

7.3  Securities Law Filings and Other Disclosures. Notwithstanding any provision of this Agreement to the contrary, 
either  Party  may  disclose  the  terms  of  this  Agreement  to  the  extent  required,  in  the  advice  of  such  Party’s  legal  counsel,  to 
comply with Applicable Law, including the rules and regulations promulgated by the SEC, AMF or any equivalent Governmental 
Authority in any country,  or  the  rules  of  any  stock  exchange  in  which  a  Party is listed. Notwithstanding the foregoing, before 
disclosing this Agreement or any of the terms hereof pursuant to this Section 7.3 (Securities Law Filings and Other Disclosures), 
the Parties will consult with one another on the terms of this Agreement to be redacted in making any such disclosure, with the 
filing Party giving due consideration to the other Party’s input. Further, if a Party discloses this Agreement or any of the terms 
hereof in accordance with this Section 7.3 (Securities Law Filings and Other Disclosures), such Party will, at its own expense, 
maintain as confidential the portions of this Agreement and such other terms as may be reasonably requested by the other Party; 
provided, however, that the Parties agree that the financial terms in this Agreement must be redacted from any public disclosure 
except to the extent they have been previously disclosed in a press release or other publication pursuant to the Parties’ mutual 
agreement.

7.4  Publications. During the Term, BioCryst will have the sole right to publish and make scientific presentations with 
respect to the Covered Product. BioCryst shall submit all such intended publications or presentations to Clearside at least [***] 
([***]) days prior to any submission or other public disclosure. Clearside shall have [***] ([***]) days in which to review such 
proposed  publication  or  presentation,  and  BioCryst  shall  consider  Clearside’s  comments  in  good  faith  with  respect  to  such 
publication or presentation. Clearside shall have the right to remove any of its Confidential Information prior to submission for 
publication  or  presentation.  If  Clearside  fails  to  notify  BioCryst  during  the  [***]  ([***])  day  period  set  forth  above,  BioCryst 
may proceed with the proposed publication or presentation. Each Party agrees to acknowledge the contributions of the other Party 
and its employees in all publications as scientifically appropriate.

7.5  Public Announcements. The Parties will agree upon the content of one (1) or more press releases, the release of 
which the Parties will coordinate after the Effective Date. Except as may be expressly permitted under Section  7.3  (Securities 
Law Filings and Other Disclosures), neither Party will make any other public announcement regarding this Agreement without 
the  prior  written  approval  of  the  other  Party.  Notwithstanding  the  foregoing,  BioCryst  and  its  Affiliates  and  its  and  their 
Distributors  and  Sublicensees  will  have  the  right  to  publicly  disclose  research,  development  and  commercial  information 
(including with respect to regulatory matters) regarding the Covered Product; provided, that such disclosure: (a) does not contain 
non-public or Confidential Information related to any Clearside Device; and (b) does not contain any claims relating to the use of 
any  Clearside  Device  in  a  manner  that  is  contrary  to,  or  would  not  reasonably  be  expected  have  an  adverse  effect  on,  any 
Regulatory Approval held by Clearside related to any Clearside Device. For the sake of clarity, nothing in this Agreement will 
prevent either Party from making any public disclosure relating to this Agreement or any Clearside Device if the contents of such 
public  disclosure  have  previously  been  made  public  other  than  through  a  breach  of  this  Agreement  by  the  issuing  Party  or  its 
Affiliates.

7.6  Return of Confidential Information. Upon expiration or termination of this Agreement, the Receiving Party will 
promptly return all of the Disclosing Party’s Confidential Information, including all copies thereof in any medium, except that the 
Receiving Party may retain one archival copy for its legal files for record keeping purposes only. The Receiving Party will also 
be permitted to retain such additional copies of or any computer records or files containing the Disclosing Party’s Confidential 
Information that have been created solely by automatic archiving and back-up procedures, to the extent created and retained in a 
manner consistent with the Receiving Party’s standard archiving and back-up procedures, but not for any other use or purpose.

performance of any of its material obligations under this Agreement, in addition to any other right and remedy the other Party

[***] ([***]) days (the “Notice Period”) prior written notice (the “Termination Notice”) to the Breaching Party and specifying
the breach and its claim of right to terminate; provided that: (i) the termination will not become effective at the end of the Notice 
Period  if  the  Breaching  Party  cures  the  breach  specified  in  the  Termination  Notice  during  the  Notice  Period  and,  provided, 
further, that, to the extent such breach is curable, the Breaching Party’s cure right will be extended for up to an additional [***]

Covered Product due to a Material Safety Issue; or

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE

10.4 Procedure.

(a)  Notice. Each Party will notify the other Party in writing in the event it becomes aware of a claim for which 
indemnification may be sought hereunder. In the event that any Third Party asserts a claim or other proceeding with respect to 
any matter for which a Party (the “Indemnified Party”) is entitled to indemnification hereunder (a “Third Party Claim”), then 
the Indemnified Party will promptly notify the Party obligated to indemnify the Indemnified Party (the “Indemnifying  Party”) 
thereof; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party will relieve the 
Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced 
thereby.

(b)  Control. The Indemnifying Party will have the right, exercisable by notice to the Indemnified Party within 
[***]  ([***])  Business  Days  after  receipt  of  notice  from  the  Indemnified  Party  of  the  assertion  of  any  Third  Party  Claim,  to 
participate in and to assume the defense thereof with counsel of its choice, which counsel will be reasonably acceptable to the 
Indemnified Party; provided that an Indemnified Party will have the right to retain its own counsel at its own expense. 

(c)  Settlement.  The  Indemnifying  Party  will  not  be  liable  for  any  damages  with  respect  to  any  Third  Party 
Claim that is settled or compromised by the Indemnified Party without the Indemnifying Party’s prior written consent, not to be 
unreasonably withheld, conditioned or delayed. No offer of settlement, compromise or settlement by the Indemnifying Party will 
be  binding  on  an  Indemnified  Party  without  the  Indemnified  Party’s  prior  written  consent  (not  to  be  unreasonably  withheld, 
conditioned or delayed), unless such settlement or compromise (i) fully 

46

 
 
CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY [***], HAS BEEN OMITTED BECAUSE 
IT IS BOTH (I) NOT MATERIAL AND (II) THE TYPE THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL.

releases  the  Indemnified  Party  without  any  liability,  loss,  cost  or  obligation,  and  (ii)  admits  no  liability,  wrongdoing  or  other 
admission against interest on the part of the Indemnified Party.

10.5 Insurance. Each Party will have and maintain, at its sole cost and expense, adequate liability insurance, (including 
product  liability  insurance,  employers  liability,  statutory  Workers  Compensation  and  contractual  liability)  to  protect  against 
potential liabilities and risk arising out of activities to be performed under this Agreement and any agreement related hereto and 
upon  such  terms  (including  coverages,  deductible  limits  and  self-insured  retentions)  as  are  customary  in  the  pharmaceutical 
industry generally for the activities to be conducted by such Party under this Agreement, but in no event less than [***] Dollars 
($[***])  per  occurrence  for  personal  injury  and  [***]  Dollars  ($[***])  per  occurrence  for  property  damage.  Such  liability 
insurance program will insure against all types of liability, including personal injury, physical injury or property damage arising 
out of such Party’s activities hereunder. All insurance coverage required under this Agreement shall be primary to any coverage 
carried  by  an  Indemnified  Party,  shall  waive  all  rights  of  subrogation  against  any  additional  insured  and  shall  be  placed  with 
insurers whose A.M. Best’s rating is at least [***]. Such liability insurance program will require any insurance carrier to provide 
the  Parties  with  no  less  than  [***]  ([***])  days’  written  notice  of  any  change  in  the  terms  or  coverage  of  the  policy  or  its 
cancellation and, if written on a “claims made” basis, either Party will provide coverage for [***] years after termination of this 
Agreement.  This  Section  10.5  (Insurance)  will  not  create  any  limitation  on  the  Parties’  liability  under  this  Agreement.  Such 
insurance  information  will  be  kept  in  confidence  in  the  same  manner  as  any  other  Confidential  Information  disclosed  by  the 
Parties hereunder.

ARTICLE 11
MISCELLANEOUS

11.1 Assignment. The rights arising under this Agreement may not be assigned or otherwise transferred by either Party 
without the prior written consent of the other Party, not to be unreasonably withheld, conditioned or delayed; provided, however, 
that either Party may assign such rights without the consent of the other Party (a) to any of its Affiliates; or (b)  to  any  Person 
acquiring  all  or  substantially  all  of  its  assets  or  business  to  which  this  Agreement  relates,  whether  by  merger,  sale  of  assets, 
operation of law or otherwise. In all cases, the assigning Party will provide the other Party with prompt written notice of any such 
assignment. No assignment of rights under this Agreement will act as a novation. Any assignment not in accordance with this 
Section 11.1 (Assignment) will be null and void.

11.2 Rights in Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by Clearside are and 
will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any 
other  country  or  jurisdiction,  licenses  of  right  to  “intellectual  property”  as  defined  under  Section  101  of  the  U.S.  Bankruptcy 
Code. The Parties agree that BioCryst, as licensee of such rights under this Agreement, will retain and may fully exercise all of 
its  rights  and  elections  under  the  U.S.  Bankruptcy  Code  or  any  analogous  provisions  in  any  other  country  or  jurisdiction.  The 
Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Clearside under the U.S. 
Bankruptcy Code or any analogous provisions in any other country or jurisdiction, BioCryst will

be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments 
of such intellectual property, which, if not already in BioCryst’s possession, will be promptly delivered to it (a) upon any such 
commencement  of  a  bankruptcy  proceeding  upon  BioCryst’s  written  request  therefor,  unless  Clearside  elects  to  continue  to 
perform all of its obligations under this Agreement or (b) if not delivered under clause (a) above, following the rejection of this 
Agreement by or on behalf of Clearside upon written request therefor by BioCryst.

11.3 Further Actions.  Each Party agrees to  execute,  acknowledge  and  deliver  such  further  instruments, and to do all 

such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of the Agreement.

11.4 Force Majeure. Any delay in performance by any Party under this Agreement will not be considered a breach of 
this  Agreement  if  and  to  the  extent  caused  by  occurrences  beyond  the  reasonable  control  of  the  Party  affected,  potentially 
including but not limited to acts of God, embargoes, governmental restrictions, strikes (but not strikes of the delayed Party) or 
other concerted acts of workers, fire, flood, earthquakes, explosions, riots, wars, civil disorder, rebellion or sabotage. The Party 
suffering such occurrence will immediately notify the other Party, and any time for performance hereunder will be extended by 
the actual time of delay caused by the occurrence.

11.5 Notices. All communications required to be made under this Agreement will be sent to the addresses set out below, 
or  to  such  other  addresses  as  may  be  designated  by  one  Party  to  the  other  by  notice  pursuant  hereto,  by  (a)  internationally

11.6 Amendment .  No  amendment,  modification  or  supplement  of  any  provision  of  this  Agreement  will  be  valid  or 

effective unless made in writing and signed by a duly authorized officer of each Party.

11.7 Waiver. No waiver by either Party hereto of any breach or default hereunder will be deemed a waiver as to any 
subsequent or similar breach or default. The failure of any Party to assert any of its rights under this Agreement or otherwise will 
not constitute a waiver of such rights.

11.8 Severability .  If  any  clause  or  portion  thereof  in  this  Agreement  is  for  any  reason  held  to  be  invalid,  illegal  or

will be construed in such fashion as to maintain its existence, validity and enforceability to the greatest extent possible. In any
such event, this Agreement will be construed as if such clause or portion thereof had never been contained in this Agreement, and 
there will be deemed substituted therefor such provision as will most nearly carry out the intent of the Parties as expressed in this 
Agreement to the fullest extent permitted by Applicable Law.

interpreting any of the provisions of this Agreement.

11.11 

Dispute  Resolution .  Except  as  provided  in  Section  5.11  (Audit  Dispute)  and  Section  9.2(e)  (Alternative 
Remedy  in  Lieu  of  Termination),  any  dispute,  controversy  or  claim  arising  out  of,  relating  to  or  in  connection  with  this 
Agreement,  including  with  respect  to  its  formation,  interpretation,  applicability,  breach,  termination,  validity  or  enforceability 
thereof will be referred to the CEO of Clearside and the CEO of BioCryst (or their respective designee who has the authority to 
make decisions on behalf of such Party) who will negotiate in good faith to resolve the dispute. Either Party may initiate such 
informal  dispute  resolution  by  sending  written  notice  of  the  dispute  to  the  other  Party.  If  any  dispute  is  not  resolved  by  these 
individuals (or their designees) within [***] ([***]) days after written notice of the dispute, or such longer period as they may 
mutually agree, either Party may refer the dispute to arbitration in accordance with this Section 11.11 (Dispute Resolution).

Any  arbitration  under  this  Agreement  shall  be  conducted  by  three  arbitrators  and  administered  by  the  American 
Arbitration Associations (the “AAA”) in accordance with its Commercial Arbitration Rules (“Rules”) in effect at the time, except 
as  they  may  be  modified  herein  or  by  agreement  of  the  Parties.  The  claimant  shall  nominate  an  arbitrator  in  its  demand  for 
arbitration. The respondent shall nominate an arbitrator within [***] days of the receipt of the demand for arbitration. The two 
arbitrators nominated by the parties shall nominate a third arbitrator within [***] days after the nomination of the later-nominated 
arbitrator. The third arbitrator shall act as chair of the tribunal. If any of the three arbitrators are not nominated within the time 
prescribed above, then the AAA shall appoint the arbitrator(s) in accordance with its Rules. The seat of arbitration shall be New 
York, New York. The award rendered by the arbitral tribunal shall be final and binding upon the Parties, and may be enforced as 
an arbitral award and entered as a judgment in any court of competent jurisdiction. 

The Parties agree that any dispute under the Agreement shall be kept confidential. The existence of the dispute and any 
arbitration, any non-public information provided in an arbitration, and any submissions, orders or awards made in an arbitration 
(together, the “Confidential Dispute Information”) shall not be disclosed to any non-party except the tribunal, the AAA, their 
counsel, experts, witnesses, accountants and auditors, insurers and reinsurers, and any other person necessary to the conduct of 
the dispute. Notwithstanding the foregoing, a party may disclose Confidential Dispute Information to the extent that disclosure 
may  be  required  to  fulfill  a  legal  duty,  protect  or  pursue  a  legal  right,  or  enforce  or  challenge  an  award  in  bona  fide  legal 
proceedings.  The  provisions  of  this  Section  11.11  (Dispute  Resolution)  will  survive  the  termination  or  expiration  of  this 
Agreement.

11.12 

Compliance with Laws. Each Party will, and will ensure that its Affiliates will, comply with all Applicable 
Law in exercising its rights and fulfilling its obligations under this Agreement. No Party will, or will be required to, undertake 
any  activity  under  or  in  connection  with  this  Agreement  which  violates,  or  which  it  believes,  in  good  faith,  may  violate,  any 
Applicable Law.

complete, final and exclusive understanding and agreement of the Parties and cancel and supersede any and all prior negotiations, 
correspondence, understandings and

agreements,  whether  oral  or  written,  between  the  Parties  respecting  the  subject  matter  hereof  and  thereof,  including  the 
Confidentiality  Agreement,  the  Material  Transfer  Agreement,  and  the  Technology  Access  Agreement,  which  are  hereby 
terminated effective as of the Effective Date.

11.14 

Independent  Contractors .  Both  Parties  are  independent  contractors  under  this  Agreement.  Nothing  herein 
contained will be deemed to create an employment, agency, joint venture or partnership relationship between the Parties hereto or 
any of their agents or employees, or any other legal arrangement that would impose liability upon one Party for the act or failure 
to act of the other Party. Neither Party will have any express or implied power to enter into any contracts or commitments or to 
incur any liabilities in the name of, or on behalf of, the other Party, or to bind the other Party in any respect whatsoever.

11.15 

Cumulative Rights. The rights, powers and remedies hereunder will be in addition to, and not in limitation of, 
all rights, powers and remedies provided at law or in equity, or under any other agreement between the Parties. All of such rights, 
powers and remedies will be cumulative, and may be exercised successively or cumulatively.

11.16 

Counterparts. This Agreement may be executed in two (2) counterparts, each of which will be an original and 
both of which will constitute together the same document. Counterparts may be signed and delivered by facsimile or PDF file, 
each of which will be binding when received by the applicable Party. Electronically scanned signatures shall have the same effect 
as their originals.

11.17 

Interpretation. Unless the context of this Agreement otherwise requires: (a) words of one gender include the 
other gender; (b) words using the singular or plural number also include the plural or singular number, respectively; (c) the terms 
“hereof,”  “herein,”  “hereby,”  and  other  similar  words  refer  to  this  entire  Agreement;  (d)  the  words  “include”,  “includes”,  and 
“including”  when  used  in  this  Agreement  will  be  deemed  to  be  followed  by  the  words  “without  limitation”,  unless  otherwise 
specified; (e)  the  terms  “Article”  and  “Section”  refer  to  the  specified  Article  and  Section  of  this  Agreement;  and  (f)  the  word 
“withheld” in the phrases “withheld unreasonably” or “unreasonably withheld” and other forms of such words, will be deemed to 
be followed by the words “conditioned or delayed,” (g) the word “or” is used in the inclusive sense (and/or); and (h) references to 
any  specific  law,  rule,  or  regulation,  or  article,  section,  or  other  division  thereof,  will  be  deemed  to  include  the  then-current 
amendments thereto or any replacement or successor law, rule, or regulation thereof.

11.18 

Expenses .  Except  as  otherwise  expressly  provided  in  this  Agreement,  each  Party  shall  pay  the  fees  and 
expenses  of  its  respective  lawyers  and  other  experts  and  all  other  expenses  and  costs  incurred  by  such  Party  incurred  in 
connection with the negotiation, preparation, execution, delivery, and performance of this Agreement.

11.19 

No  Third  Party  Rights  or  Obligations .  Notwithstanding  a  Clearside  Indemnified  Party  or  a  BioCryst 
Indemnified Party’s right to indemnification under Section 10.2 (Indemnification by BioCryst) and Section 10.3 (Indemnification 
by  Clearside)  (which,  for  clarity,  must  be  exercised  through  a  Party  and  may  not  be  exercised  directly  by  such  Persons),  no 
provision

of this Agreement will be deemed or construed in any way to result in the creation of any rights or obligation in any Person not a 
Party to this Agreement. However, either Party may decide, in its sole discretion, to use one or more of its Affiliates to perform 
its obligations and duties hereunder, provided that such deciding Party will remain liable hereunder for the performance by any

1.

Amendment  of  Section  3.4.    The  Parties  agree  that  Section  3.4  of  the  Agreement  is  hereby  amended  to  read  in  its 
entirety as follows:

“3.4  Sublicensee Payments. Within thirty (30) days of receipt by COMPANY, or no later than March 31, 2025 
with respect to amounts received by Company on or after July 1, 2023 but prior to January 1, 2025, COMPANY

fees,  milestone  fees,  maintenance  fees  and  minimum  royalty  payments,  but  excluding  (i)  amounts  paid  to 
COMPANY  by  a  Sublicensee  on  or  after  July  1,  2023  to  reimburse  COMPANY  for  actual  costs  (including

maintenance  and  enforcement  of  intellectual  property  rights  covering  Licensed  Products  (collectively, 
“Reimbursed  Costs”),  provided  that  such  Reimbursed  Costs  are  paid  to  COMPANY  pursuant  to  a  written 
agreement between COMPANY and such Sublicensee that expressly provides for reimbursement to COMPANY 
by such Sublicensee of such Reimbursed Costs, (ii) the value of any intellectual property rights transferred or 
granted  to  COMPANY  if  such  rights  are  necessary  or  helpful  to  the  development  or  commercialization  of 
Licensed  Products  and  (iii)  amounts  paid  for  shares  of  Company  stock.  If  COMPANY  in-licenses  third  party 
technology and/or intellectual property rights and incorporates it into Licensed Product, and receives sublicense 
revenue  with  respect  to  such  Licensed  Product,  then  the  [***]  percent  ([***]%)  sublicense  revenue  sharing
provided  for  above  shall  apply  to  that  portion  of  the  value  of  the  Licensed  Product  that  is  attributable  to  the 
intellectual property licensed from LICENSOR. For example, the sublicense revenue that is subject to sharing 
with  LICENSOR  shall  be  that  fraction  A/(A+B)  of  non-royalty  revenue  received  where  A  is  the  amount 
attributable to the LICENSOR intellectual property, and B is the aggregate amount attributable to the remainder 
of the technology so licensed. If it is not feasible to accurately determine such amounts, then the allocation shall 
be  commercially  reasonable  and  determined  by  good  faith  negotiation  between  COMPANY  and  LICENSOR. 
COMPANY shall not structure any sublicense of the Licensed Patents and/or Licensed Technology, alone or in 
connection  with  other  assets  (e.g.,  technology,  know-how,  and/or  intellectual  property  rights)  owned  or 
controlled by COMPANY, in a single transaction or series of related transactions, in order to minimize or avoid 
payments to LICENSOR under this Section 3.4.”

Consultant will be paid a monthly consulting fee of $8,000 for each calendar month during the Term of this 
Agreement beginning on March 1, 2023 (the “Monthly Consulting Fee”). Any undisputed Monthly Consulting Fee 
will be paid on a monthly basis within thirty (30) days following Client’s receipt of Consultant’s invoice (as described

shall be prorated based on the number of days this Agreement was in effect for such partial calendar month. For 
Services rendered in February 2023, Consultant will be paid a pro-rated portion of the Monthly Consulting Fee based 
on the number of days this Agreement was in effect for such month.

Equity Vesting. Consultant has been granted equity compensation in the form of stock options and Restricted Stock 
Unit awards, in connection with Consultant’s prior employment relationship with the Client (the “Equity Grants”). 
Notwithstanding anything to the contrary in Consultant’s Stock Option Grant Notices and Agreements and 
Consultant’s Restricted Stock Unit Grant Notices and Agreements to the contrary, then effective as of the Effective 
Date of this Agreement, Consultant acknowledges and agrees that:

• All vesting with respect to any restricted stock units (each, an “RSU”) held by Consultant as of the Termination 
Date ceased as of the Termination Date, with the remaining unvested RSUs being cancelled and of no further force or 
effect;

• Except as provided in the immediately following paragraphs, any options to purchase shares of the Client’s Common 
Stock (each, an “Option”) held by Consultant as of the Termination Date will continue to vest in accordance with their 
terms through August 31, 2023, provided that

 
 
 
 
 
Consultant remains in continuous service with the Client through such date, with any then-remaining unvested 
Option shares being cancelled and of no further force or effect;

• With respect to that certain Option granted to Consultant on January 4, 2023 (the “January 2023 Option”), the 
January 2023 Option will continue to vest in accordance with its terms through January 4, 2024, provided that 
Consultant remains in continuous service with the Client through January 4, 2024, at which time 25% of the January 
2023 Option shares (46,875 shares) will immediately vest and become exercisable with any then remaining unvested 
January 2023 Option shares being cancelled and of no further force or effect;

• With respect to that certain Option granted to Consultant on January 18, 2024 (the “January 2024 Option”), the

that Consultant remains in continuous service with the Client on each such vesting date;

Any then-outstanding and vested Options shall remain exercisable until the date that is three months following the 
termination date of this Agreement (subject in any event to earlier expiration in accordance with the agreements 
evidencing such Options and the terms of the plan pursuant to which such Option was granted); and

Any Options originally intended to qualify as incentive stock options under Section 422 of the U.S. Internal Revenue 
Code of 1986, as amended, shall no long so qualify if exercised more than 3 months after the Termination Date.

Consultant acknowledges and agrees that the extension of his exercise period, as described above, is a substantial 
benefit to him and constitutes additional consideration for the Services hereunder and for Consultant’s entering into 
this Agreement.

Consultant will be reimbursed for third party expenses (at cost) if approved in writing in advance by Client.

Consultant will invoice Client monthly (on the first day of each month, beginning on April 1, 2023) for services 
rendered and expenses incurred during the previous month and will provide such reasonable receipts or other 
documentation of expenses as Client might request, including copies of time records. The parties have executed this

CLEARSIDE BIOMEDICAL, INC.

INCENTIVE COMPENSATION RECOUPMENT POLICY

1.

INTRODUCTION

The Board of Directors (the “Board”) of Clearside Biomedical, Inc., a Delaware corporation (the “Company”), has determined that 
it  is  in  the  best  interests  of  the  Company  and  its  stockholders  to  adopt  this  Incentive  Compensation  Recoupment  Policy  (this  “Policy”) 
providing  for  the  Company’s  recoupment  of  Recoverable  Incentive  Compensation  that  is  received  by  Covered  Officers  of  the  Company 
under certain circumstances. Certain capitalized terms used in this Policy have the meanings given to such terms in Section 3 below.

This Policy is designed to comply with, and shall be interpreted to be consistent with, Section 10D of the Exchange Act, Rule 10D-

1 promulgated thereunder (“Rule 10D-1”) and Nasdaq Listing Rule 5608 (the “Listing Standards”).

2.

EFFECTIVE DATE

This  Policy  shall  apply  to  all  Incentive  Compensation  that  is  received  by  a  Covered  Officer  on  or  after  October  2,  2023  (the 
“Effective Date”). Incentive Compensation is deemed “received” in the Company’s fiscal period in which the Financial Reporting Measure 
specified in the Incentive Compensation award is attained, even if the payment or grant of such Incentive Compensation occurs after the end 
of that period.

3.

DEFINITIONS

“Accounting  Restatement”  means  an  accounting  restatement  that  the  Company  is  required  to  prepare  due  to  the  material 
noncompliance  of  the  Company  with  any  financial  reporting  requirement  under  the  securities  laws,  including  any  required  accounting 
restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that 
would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

“Accounting Restatement Date” means the earlier to occur of (a) the date that the Board, a committee of the Board authorized to 
take  such  action,  or  the  officer  or  officers  of  the  Company  authorized  to  take  such  action  if  Board  action  is  not  required,  concludes,  or 
reasonably should have concluded, that the Company is required to prepare an Accounting Restatement, or (b) the date that a court, regulator 
or other legally authorized body directs the Company to prepare an Accounting Restatement.

“Administrator” means the Compensation Committee or, in the absence of such committee, the Board.

“Code” means the U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder.

“Compensation Committee” means the Compensation Committee of the Board.

“Covered Officer” means each current and former Executive Officer.

“Exchange” means the Nasdaq Stock Market.

“Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended.

 
 
“Executive Officer” means the Company’s president, principal financial officer, principal accounting officer (or if there is no such 
accounting officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as 
sales, administration, or finance), any other officer who performs a policy-making function, or any other person who performs similar policy-
making  functions  for  the  Company.  Executive  officers  of  the  Company’s  parent(s)  or  subsidiaries  are  deemed  executive  officers  of  the 
Company if they perform such policy-making functions for the Company. Policy-making function is not intended to include policy-making 
functions  that  are  not  significant.  Identification  of  an  executive  officer  for  purposes  of  this  Policy  would  include  at  a  minimum  executive 
officers identified pursuant to Item 401(b) of Regulation S-K promulgated under the Exchange Act.

“Financial Reporting Measures” means measures that are determined and presented in accordance with the accounting principles 
used in preparing the Company’s financial statements, and any measures derived wholly or in part from such measures, including Company 
stock price and total stockholder return (“TSR”). A measure need not be presented in the Company’s financial statements or included in a 
filing with the SEC in order to be a Financial Reporting Measure.

“Incentive Compensation” means any compensation that is granted, earned or vested based wholly or in part upon the attainment of 

a Financial Reporting Measure. 

“Lookback Period” means the three completed fiscal years immediately preceding the Accounting Restatement Date, as well as any 
transition period (resulting from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years 
(except that a transition period of at least nine months shall count as a completed fiscal year). Notwithstanding the foregoing, the Lookback 
Period shall not include fiscal years completed prior to the Effective Date. 

“Recoverable Incentive Compensation” means Incentive Compensation received by a Covered Officer during the Lookback Period 
that  exceeds  the  amount  of  Incentive  Compensation  that  would  have  been  received  had  such  amount  been  determined  based  on  the 
Accounting Restatement, computed without regard to any taxes paid (i.e., on a gross basis without regarding to tax withholdings and other 
deductions). For any compensation plans or programs that take into account Incentive Compensation, the amount of Recoverable Incentive 
Compensation  for  purposes  of  this  Policy  shall  include,  without  limitation,  the  amount  contributed  to  any  notional  account  based  on 
Recoverable  Incentive  Compensation  and  any  earnings  to  date  on  that  notional  amount.  For  any  Incentive  Compensation  that  is  based  on 
stock price or TSR, where the Recoverable Incentive Compensation is not subject to mathematical recalculation directly from the information 
in an Accounting Restatement, the Administrator will determine the amount of Recoverable Incentive Compensation based on a reasonable 
estimate of the effect of the Accounting Restatement on the stock price or TSR upon which the Incentive Compensation was received. The 
Company shall maintain documentation of the determination of that reasonable estimate and provide such documentation to the Exchange in 
accordance with the Listing Standards.

“SEC” means the U.S. Securities and Exchange Commission.

4.

RECOUPMENT

(a) Applicability  of  Policy.  This  Policy  applies  to  Incentive  Compensation  received  by  a  Covered  Officer  (i)  after  beginning 
services  as  an  Executive  Officer,  (ii)  who  served  as  an  Executive  Officer  at  any  time  during  the  performance  period  for  such  Incentive 
Compensation, (iii) while the Company had a class of securities listed on a national securities exchange or a national securities association, 
and (iv) during the Lookback Period. 

(b) Recoupment Generally.  Pursuant to the provisions of this Policy, if there is an 

2

 
 
 
Accounting Restatement, the Company must reasonably promptly recoup the full amount of the Recoverable Incentive Compensation, unless 
the conditions of one or more subsections of Section 4(c) of this Policy are met and the Compensation Committee, or, if such committee does 
not  consist  solely  of  independent  directors,  a  majority  of  the  independent  directors  serving  on  the  Board,  has  made  a  determination  that 
recoupment  would  be  impracticable.  Recoupment  is  required  regardless  of  whether  the  Covered  Officer  engaged  in  any  misconduct  and 
regardless of fault, and the Company’s obligation to recoup Recoverable Incentive Compensation is not dependent on whether or when any 
restated financial statements are filed.  

(c) Impracticability of Recovery. Recoupment may be determined to be impracticable if, and only if:

(i)

the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount of the applicable 
Recoverable  Incentive  Compensation;  provided  that,  before  concluding  that  it  would  be  impracticable  to  recover  any  amount  of 
Recoverable Incentive Compensation based on expense of enforcement, the Company shall make a reasonable attempt to recover 
such Recoverable Incentive Compensation, document such reasonable attempt(s) to recover, and provide that documentation to the 
Exchange in accordance with the Listing Standards; or

(ii)

recoupment of the applicable Recoverable Incentive Compensation would likely cause an otherwise tax-qualified 
retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Code 
Section 401(a)(13) or Code Section 411(a) and regulations thereunder.

(d) Sources of Recoupment.  To the extent permitted by applicable law, the Administrator shall, in its sole discretion, determine the 
timing and method for recouping Recoverable Incentive Compensation hereunder, provided that such recoupment is undertaken reasonably 
promptly.  The  Administrator  may,  in  its  discretion,  seek  recoupment  from  a  Covered  Officer  from  any  of  the  following  sources  or  a 
combination thereof, whether the applicable compensation was approved, awarded, granted, payable or paid to the Covered Officer prior to, 
on  or  after  the  Effective  Date:  (i)  direct  repayment  of  Recoverable  Incentive  Compensation  previously  paid  to  the  Covered  Officer;  (ii) 
cancelling prior cash or equity-based awards (whether vested or unvested and whether paid or unpaid); (iii) cancelling or offsetting against 
any planned future cash or equity-based awards; (iv) forfeiture of deferred compensation, subject to compliance with Code Section 409A; 
and (v) any other method authorized by applicable law or contract. Subject to compliance with any applicable law, the Administrator may 
effectuate  recoupment  under  this  Policy  from  any  amount  otherwise  payable  to  the  Covered  Officer,  including  amounts  payable  to  such 
individual under any otherwise applicable Company plan or program, e.g., base salary, bonuses or commissions and compensation previously 
deferred by the Covered Officer. The Administrator need not utilize the same method of recovery for all Covered Officers or with respect to 
all types of Recoverable Incentive Compensation.

(e) No Indemnification of Covered Officers. Notwithstanding any indemnification agreement, applicable insurance policy or any 
other agreement or provision of the Company’s certificate of incorporation or bylaws to the contrary, no Covered Officer shall be entitled to 
indemnification  or  advancement  of  expenses  in  connection  with  any  enforcement  of  this  Policy  by  the  Company,  including  paying  or 
reimbursing such Covered Officer for insurance premiums to cover potential obligations to the Company under this Policy.

(f) Indemnification of Administrator. Any members of the Administrator, and any other members of the Board who assist in the 

administration of this Policy, shall not be personally liable for any 

3

 
 
 
action, determination or interpretation made with respect to this Policy and shall be indemnified by the Company to the fullest extent under 
applicable law and Company policy with respect to any such action, determination or interpretation. The foregoing sentence shall not limit 
any other rights to indemnification of the members of the Board under applicable law or Company policy.

(g) No “Good Reason” for Covered Officers.  Any action by the Company to recoup or any recoupment of Recoverable Incentive 
Compensation under this Policy from a Covered Officer shall not be deemed (i) “good reason” for resignation or to serve as a basis for a 
claim of constructive termination under any benefits or compensation arrangement applicable to such Covered Officer, or (ii) to constitute a 
breach of a contract or other arrangement to which such Covered Officer is party.

5.

ADMINISTRATION

Except as specifically set forth herein, this Policy shall be administered by the Administrator. The Administrator shall have full and 
final authority to make any and all determinations required under this Policy.  Any determination by the Administrator with respect to this 
Policy shall be final, conclusive and binding on all interested parties and need not be uniform with respect to each individual covered by this 
Policy. In carrying out the administration of this Policy, the Administrator is authorized and directed to consult with the full Board or such 
other committees of the Board as may be necessary or appropriate as to matters within the scope of such other committee’s responsibility and 
authority. Subject to applicable law, the Administrator may authorize and empower any officer or employee of the Company to take any and 
all  actions  that  the  Administrator,  in  its  sole  discretion,  deems  necessary  or  appropriate  to  carry  out  the  purpose  and  intent  of  this  Policy 
(other than with respect to any recovery under this Policy involving such officer or employee).

6.

SEVERABILITY

If  any  provision  of  this  Policy  or  the  application  of  any  such  provision  to  a  Covered  Officer  shall  be  adjudicated  to  be  invalid, 
illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Policy, and 
the invalid, illegal or unenforceable provisions shall be deemed amended to the minimum extent necessary to render any such provision or 
application enforceable.

7.

NO IMPAIRMENT OF OTHER REMEDIES

Nothing contained in this Policy, and no recoupment or recovery as contemplated herein, shall limit any claims, damages or other 
legal  remedies  the  Company  or  any  of  its  affiliates  may  have  against  a  Covered  Officer  arising  out  of  or  resulting  from  any  actions  or 
omissions by the Covered Officer. This Policy does not preclude the Company from taking any other action to enforce a Covered Officer’s 
obligations to the Company, including, without limitation, termination of employment and/or institution of civil proceedings. This Policy is in 
addition  to  the  requirements  of  Section  304  of  the  Sarbanes-Oxley  Act  of  2002  (“SOX 304”)  that  are  applicable  to  the  Company’s  Chief 
Executive  Officer  and  Chief  Financial  Officer  and  to  any  other  compensation  recoupment  policy  and/or  similar  provisions  in  any 
employment, equity plan, equity award, or other individual agreement, to which the Company is a party or which the Company has adopted 
or may adopt and maintain from time to time; provided, however, that compensation recouped pursuant to this policy shall not be duplicative 
of  compensation  recouped  pursuant  to  SOX  304  or  any  such  compensation  recoupment  policy  and/or  similar  provisions  in  any  such 
employment, equity plan, equity award, or other individual agreement except as may be required by law.

8.

AMENDMENT; TERMINATION

The Administrator may amend, terminate or replace this Policy or any portion of this Policy at any time and from time to time in its 

sole discretion. The Administrator shall amend this Policy as it deems necessary to comply with applicable law or any Listing Standard.

9.

SUCCESSORS

This  Policy  shall  be  binding  and  enforceable  against  all  Covered  Officers  and,  to  the  extent  required  by  Rule  10D-1  and/or  the 

applicable Listing Standards, their beneficiaries, heirs, executors, administrators or other legal representatives.

10.  REQUIRED FILINGS

The Company shall make any disclosures and filings with respect to this Policy that are required by law, including as required by the 

SEC.
