Petros begins enrollment in AI integrated Human Factors Study to optimize self-screening, continuing its efforts to make STENDRA (avanafil) the first erectile dysfunction medication to achieve OTC Status (Please see important safety information below) NEW YORK, NY / ACCESSWIRE / March 19, 2024 / Petros Pharmaceuticals, Inc. (NASDAQ:PTPI), a company focused on expanding consumer access to medication through over-the- counter (OTC) drug development programs, announces it has successfully launched its artificial intelligence (AI) tool developed as a result of its collaboration with a multi-billion-dollar software developer. The tool is being integrated into the Company's web app being used for patient self-screening, which it is testing in its recently launched Human Factors study. Fady Boctor, Petros' President and Chief Commercial Officer, commented, "The utilization of AI is a logical progression as we aim to optimize the safe administration of STENDRA (avanafil), in development for OTC availability. In addition, based on our recent interaction with the FDA on our technology approach, we believe the AI component directly addresses requests made by the Agency in order to optimize selection. Ultimately, we believe the AI will help us to gather information to ensure that the patient is appropriate to receive the drug. Importantly, we continue to believe that we have sufficient funding to achieve our development goals as well as significant near-term clinical milestones for STENDRA." The Human Factors Study, which incorporates the AI tool, is designed to assess whether the web tool developed by the company can be used safely and effectively by its intended users. Subjects will be asked to perform critical tasks with the web app without any guidance from the study staff. The study is based on applicable FDA guidance for human factors studies. The outcomes from this study will further contribute to discussions with the U.S. Food and Drug Administration (FDA) regarding the need for the Additional Condition of Nonprescription Use (ACNU) with regard to the web app and the Company's endeavors to develop STENDRA into the first erectile dysfunction medication to go OTC. About Petros Pharmaceuticals Petros Pharmaceuticals is committed to the goal of becoming a leading innovator in the emerging self-care market driving expanded access to key prescription pharmaceuticals as Over-the-Counter treatment options. Currently, Petros is pursuing increased access for its flagship prescription ED therapy, STENDRA, via potential OTC designation. If ultimately approved by the FDA for OTC access, STENDRA may be the first in its class to achieve this marketing status, also establishing company know how as a proven platform for other prospective prescription therapeutics. About the OTC Pathway The process of switching a prescription medication to over the counter (OTC) first involves the design of a Drug Facts Label (DFL) that is well understood by potential consumers. Then data must show that consumers can make an appropriate decision to use or not to use the product based only upon the information on the DFL and their personal medical history. Then consumers must demonstrate that they can properly use the product based upon the information on the DFL. To accomplish these things, the FDA ordinarily requires a consumer tested OTC DFL. This testing includes conduct of iterative Label Comprehension Studies (LCS) in the general population, Self-Selection Studies (SSS) in a population interested in using the product and in specific populations who may be harmed if they use the product, and usually one Actual Use Trial (AUT) demonstrating safe and appropriate use by consumers in a simulated OTC setting. The regulations that FDA is currently finalizing introduced Additional Conditions for Nonprescription Use (ACNU) criteria that enable correct self-selection by consumers and may expand OTC access to medications that formerly could only be available by prescription. An ACNU may be an innovative computerized tool, or the additional conditions may use other approaches that support the switch process. Important Safety Information about STENDRA® (avanafil) STENDRA® (avanafil), originally launched by Auxilium Pharmaceuticals prior to that company's sale to Endo Pharmaceuticals, is an oral phosphodiesterase 5 (PDE5) inhibitor for the treatment of erectile dysfunction. STENDRA is not for use in women or children. It is not known if STENDRA is safe and effective in women or children under 18 years of age. (A 100-mg and 200-mg tablet can be taken as early as ~15 minutes before sexual activity. STENDRA only works with sexual stimulation and should not be taken more than once a day. STENDRA can be taken with or without food; do not drink too much alcohol when taking STENDRA (for example, more than 3 glasses of wine or 3 shots of whiskey) as it can increase chances of side effects. Of people enrolled in clinical trials, 1.4%, 2.0%, and 2.0%, respectively, stopped taking STENDRA (50 mg, 100 mg, or 200 mg) due to side effects compared to 1.7% on placebo. STENDRA® was designed and developed expressly for erectile dysfunction. STENDRA is contraindicated with any form of organic nitrates, in patients with known hypersensitivity to any component of the tablet, and in patients who are using a guanylate cyclase stimulator. Patients should not use STENDRA if sexual activity is inadvisable due to cardiovascular status or any other reason. Before taking STENDRA tell your doctor if you have had any kind of heart issues including heart attack, heart failure, angina and irregular heartbeat or have elevated or low blood pressure. Use of STENDRA with alpha-blockers, other antihypertensives, or substantial amounts of alcohol (greater than 3 units) may lead to hypotension. Patients should seek emergency treatment if an erection lasts greater than 4 hours. Patients should stop STENDRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of Non Arteritic Ischemic Optic Neuropathy (NAION). Discuss with patients the increased risk of NAION in patients with a history of NAION. Patients should stop taking STENDRA and seek prompt medical attention in the event of sudden decrease or loss of hearing. STENDRA can potentiate the hypotensive effect of nitrates, alpha blockers, antihypertensives, and alcohol. CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin) increase STENDRA exposure. For patients taking concomitant strong CYP3A4 inhibitors (including ketoconazole, ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir and telithromycin), do not use STENDRA. Combination with Other PDE5 Inhibitors or Erectile Dysfunction Therapies is not recommended. The safety of STENDRA is unknown in patients with bleeding disorders and patients with active peptic ulceration. The use of STENDRA offers no protection against sexually transmitted diseases including HIV. Consider counseling patients on protective measures for sexually transmitted diseases. The most common adverse reactions reported with use of STENDRA include headache, flushing, nasal congestion, nasopharyngitis, and back pain. For more information about STENDRA, call 844-458-4887. If you would like to report an adverse event or product complaint, please contact us at 844-458-4887. You are encouraged to report negative side effects of prescription drugs to the FDA by calling 1-800-FDA-1088, or at . Please see the full Prescribing Information and Patient Information.

A successful year including NASDAQ listing and positive results from two Phase 3 programs in OCS-01: Phase 3 Stage 1 DIAMOND trial for Diabetic Macular Edema (DME), and Phase 3 OPTIMIZE-1 trial for inflammation and pain following cataract surgery On-track to report topline data from OCS-02 (Licaminlimab) Phase 2b RELIEF trial in Dry Eye Disease (DED) in Q2 2024, OCS-01 Phase 3 OPTIMIZE-2 trial, and OCS-05 proof-of-concept ACUITY trial in Q4 2024 Cash, cash equivalents and short-term investments of $108.9 million funding operations and planned clinical trials, as well as advancements in DIAMOND-1 and DIAMOND-2 Phase 3 trials R&D Day held on February 28, 2024, showcasing OCS-01 DME and OCS-02 DED and their transformative treatment potentials ZUG, Switzerland and BOSTON, March 18, 2024 (GLOBE NEWSWIRE) -- Oculis Holding AG (Nasdaq: OCS) (“Oculis” or the “Company”), a global biopharmaceutical company purposefully driven to save sight and improve eye care, today announced fourth quarter and full year financial results for the period ended December 31, 2023, and an overview of the Company’s progress. Riad Sherif M.D., Chief Executive Officer of Oculis: “2023 was a remarkable milestone-rich year for Oculis. Following our listing on NASDAQ, we had two positive Phase 3 data readouts with OCS-01, the first topical candidate with compelling data in DME, and achieved a strong close of the year with the initiation of three clinical trials, including the OCS-02 Phase 2b RELIEF trial in DED. As our innovative and diversified pipeline continues to advance, we remain laser-focused on delivering our key programs: OCS-01 in DME, OCS-02 in DED and OCS-05 in Acute Optic Neuritis. We are confident and excited as we move into a catalyst-rich 2024 and look forward to updating everyone on the upcoming RELIEF trial readout planned in Q2, the second Phase 3 OPTIMIZE-2 trial readout of OCS-01 in ocular surgery in Q4, which will allow us to submit our first NDA, in addition to the ACUITY trial readout of OCS-05 in Acute Optic Neuritis, also planned in Q4. I would like to thank our exceptional team and all our partners for their great contribution but also for their commitment towards our mission to save sight and improve eye care.” Q4 2023 and Recent Highlights Advanced OCS-01, a novel high concentration preservative-free topical OPTIREACH® formulation of dexamethasone with the potential to treat both front and back of the eye indications, in three ongoing pivotal trials: In DME, following the positive topline results from Stage 1 of Phase 3 DIAMOND program, the Company announced the first patient first visit in Stage 2 of the first Phase 3 DIAMOND-1 trial and in DIAMOND-2, the second Phase 3 trial required for registration. Following the positive topline results achieved in the Phase 3 OPTIMIZE-1 trial, the Company started the second Phase 3 OPTIMIZE-2 trial of OCS-01 for the treatment of inflammation and pain following cataract surgery. Achieved a record completion of patient enrolment for the Phase 2b RELIEF trial of OCS-02 (Licaminlimab), a specifically designed ophthalmic formulation of a TNFα inhibitor, eye drop formulation specifically designed with a proprietary antibody fragment technology to treat ocular inflammation. The trial, initiated in November 2023, is evaluating the efficacy and safety of OCS-02 (Licaminlimab) vs. vehicle in signs of inflammation in DED, and is further exploring its potential unique benefit in patients with a certain genotype (i.e., single-nucleotide polymorphism, SNP, related to the TNF receptor). Hosted an R&D day on February 28, 2024, with over 100 participants that featured 10 leading experts in retina and anterior segments covering OCS-01 and OCS-02 clinical programs. Presented the Phase 3 DIAMOND Stage 1 positive results of OCS-01 in DME as late-breaking abstracts at the 23rd EURETINA Congress and at the American Academy of Ophthalmology. Upcoming Clinical Milestones In 2024, the Company is focused on advancing its innovative pipeline and planned clinical development programs including: Q2 2024 OCS-02: The Phase 2b RELIEF trial evaluating topical anti-TNFα OCS-02 (Licaminlimab) efficacy and safety in DED is on track for topline results readout in Q2 2024. Q4 2024 OCS-01: Topline results from the second Phase 3 OPTIMIZE-2 trial evaluating OCS-01 once daily eye drop for the treatment of inflammation and pain following cataract surgery are anticipated by the end of 2024. If positive, the data from this trial, together with the positive results from the first Phase 3 OPTIMIZE-1 trial, are expected to support the first NDA submission of the Company. OCS-05: A serum glucocorticoid kinase-2 (SGK-2) activator and potentially disease-modifying neuroprotective candidate is initially being developed for AON. The Phase 2a PoC ACUITY trial is designed to evaluate the safety and tolerability of a once-daily injection of OCS-05 vs. placebo for 5 days, in addition to current standard of care. The trial is on track for topline readout in the fourth quarter of 2024.The Company aims to achieve IND status for OCS-05 in the U.S. in 2024. Q4 and Full Year 2023 Financial Highlights Cash position: As of December 31, 2023, the Company had total cash, cash equivalents and short-term investments of CHF 91.7 million or $108.9 million, compared to CHF 19.8 million or $21.4 million as of December 31, 2022. The increase in cash position reflects proceeds from financing transactions completed in 2023. Based on its current development plans, cash runway is expected to fund operations into late 2025. Research and development expenses were CHF 8.0 million or $9.0 million for the three-months ended December 31, 2023, compared to CHF 6.9 million or $7.1 million in the same period in 2022. The increase was primarily due to the commencement of three clinical trials during the fourth quarter of 2023: DIAMOND-1 Stage 2, OPTIMIZE-2 and RELIEF. General and administrative expenses were CHF 4.3 million or $4.9 million for the three-months ended December 31, 2023. G&A expenses remained in-line with the same period in 2022, which was CHF 4.4 million or $4.6 million. Q4 Net loss was CHF 12.5 million or $14.1 million for the fourth quarter ended December 31, 2023, compared to CHF 9.2 million or $9.5 million in the fourth quarter of 2022. The increase in net loss was primarily driven by increases in clinical development expenses, partially offset by changes in the fair value (non-cash) adjustment of outstanding warrants. FY2023 Net loss was CHF 88.8 million or $98.8 million for the year ended December 31, 2023, or CHF 2.97 or $3.31 loss per share (basic and diluted) compared to CHF 38.7 million or $40.5 million, or CHF 11.32 or $11.86 loss per share (basic and diluted) in the year ended December 31, 2022. The increase in net loss was primarily driven by the non-recurring merger and listing expense in Q1 2023, increases in clinical development expenses, public company expenses, and the fair value (non-cash) adjustment of outstanding warrants. FY2023 Non-IFRS net loss was CHF 49.0 million or $54.5 million, or CHF 1.64 or $1.83 per share, for the year ended December 31, 2023, compared to CHF 38.7 million or $40.5 million, or CHF 11.32 or $11.86 per share, for the year ended December 31, 2022. The increase in non-IFRS net loss was primarily driven by increases in clinical development expenses, G&A expenses related to operating as a public company, and an increase in the fair value (non-cash) adjustment of outstanding warrants. Non-IFRS Financial Information This press release contains financial measures that do not comply with International Financial Reporting Standards (IFRS) including non-IFRS net loss for the full year 2023, and non-IFRS net loss per common share for the same period. These non-IFRS financial measures exclude the impact of items that the Company’s management believes affect comparability or underlying business trends. These measures supplement the Company’s financial results prepared in accordance with IFRS. The Company’s management uses these measures to better analyze its financial results and better estimate its financial outlook. In management’s opinion, these non-IFRS measures are useful to investors and other users of the Company's financial statements by providing greater transparency into the ongoing operating performance of the Company and its future outlook. Such measures should not be deemed to be an alternative to IFRS requirements. The non-IFRS measures for the reported periods reflect adjustments made to exclude: Merger and listing expense, which was a one-time and non-cash expense CHF 34.9 million or $38.2 million in the first quarter of 2023 and in the year-to-date total operating expenses. During the third quarter of 2023, the Company gave effect to the impending dissolution of its Merger Sub 2 entity pursuant to the Business Combination Agreement with EBAC, which is expected to be completed in the coming months. As a result, the cumulative translation adjustments related to Merger Sub 2 previously reported in equity and recognized in other comprehensive loss, were reclassified from equity to the Condensed Consolidated Interim Statement of Loss for the year ended December 31, 2023. The resulting non-cash foreign exchange impact of such reclassification amounted to CHF 5.0 million or $5.7 million for the year ended December 31, 2023. The non-IFRS measures presented here are also unlikely to be comparable with non-IFRS disclosures released by other companies. See the “Reconciliation of Non-IFRS Measures (Unaudited)” table below for a reconciliation of these non-IFRS measures to the most directly comparable IFRS measures.
