Petros Pharmaceuticals Successfully Completes Important Study in Effort to Make STENDRA(R) (avanafil) the First Erectile Dysfunction Medication to Achieve OTC Status

Human Factor Study represents important component of FDA requirements for technology to pave way for STENDRA OTC approval

NEW YORK, NY / ACCESSWIRE / December 12, 2023 / Petros Pharmaceuticals, Inc. (Nasdaq:PTPI), a company focused on expanding consumer access to medication through over-the- counter (OTC) drug development programs, announces the completion of a Human Factors Study, whose objective was to assess the technology component developed to facilitate patient's access to its erectile dysfunction drug, STENDRA^® (avanafil), associated with the Company's intended FDA application for prescription to OTC switch.

The objective of the study was to determine the strengths and weaknesses of the interface of a developmental technology tool, as well as potential use errors in critical tasks, such as navigating and reporting medical history, entering birth date and other key call to action prompts. These tasks, if performed incorrectly - or not performed at all - have the potential to contribute to inappropriate use by the patient or user. The results of the study showed that most participants were able to navigate the tool correctly. Data from the study provided an opportunity for the Company to further optimize this technology, including reformatting of text to improve interaction, which Petros intends to implement in future studies, including additional Human Factor Studies and Self Selection studies. These components are all integral to FDA guidelines for technology-driven OTC access to medications.

Fady Boctor, Petros' President and Chief Commercial Officer, commented, "The initial usability of the emerging technology platform was encouraging, and provides us with a clear pathway forward. Participants in the study engaged with the application as intended and provided areas of improvement and/or enhancement. Under continued FDA guidance, we expect to continue our pursuit of achieving OTC designation for STENDRA, and toward the optimization of our process, which we hope to be able to replicate for other mature products looking to make the OTC switch in the future."

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.

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 Important Risk Information

STENDRA ® (avanafil) is a phosphodiesterase 5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction. STENDRA is not for use in women or children.

Contraindications

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.

Warnings and Precautions

• 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.
• Do not drink too much alcohol (for example, more than 3 glasses of wine or 3 shots of whiskey) when taking STENDRA, as this can lead to increased chances of headache, dizziness, increased heart rate, or lowered blood pressure.
• STENDRA can potentiate the hypotensive effect of nitrates, alpha blockers, antihypertensives, and alcohol. CYP3A4 inhibitors (e.g., ketoconazole, ritonavir, erythromycin) increase STENDRA exposure.
• 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 counselling patients on protective measures for sexually transmitted diseases.
