Petros Pharmaceuticals Successfully Completes AI-Integrated Formative Human Factors Study Demonstrating Positive Interaction with Web App Designed for STENDRA(R) (avanafil) OTC Switch

Study paves the way toward a first-ever innovation program to include AI-optimization for FDA-guided Rx-to-OTC switch

NEW YORK, NY / ACCESSWIRE / May 29, 2024 / Petros Pharmaceuticals, Inc. (NASDAQ:PTPI) ("Petros" or the "Company"), a company focused on expanding consumer access to medication through over-the-counter ("OTC") drug development programs, announces the successful completion of a Formative Human Factors study of its AI-integrated Web App, designed to facilitate OTC access of STENDRA^® (avanafil) for consumers. This important development follows the Company's recent execution of an AI licensing agreement with a leading multi-billion dollar software provider announced earlier this year. The Web App (previously referred to as the "technology component") is an integral part of the Company's efforts to complete an Rx-to-OTC switch for STENDRA^® (avanafil) under the guidance of the U.S. Food and Drug Administration. The study demonstrated a 90% or better error-free completion rate for nearly all 5,820 tasks assessed. The successful completion of the study paves the way for the Company to initiate the next stage of the evolving program, while continuing to optimize the AI component of the Web App.

"The successful completion of the Human Factors Study and the positive outcomes we've seen to date continue to be encouraging signs of our progress in navigating the Rx-to-OTC switch for STENDRA^® (avanafil). As we've previously indicated, we believe we have the potential to be first-in-class for the category with regards to OTC access," stated Fady Boctor, Petros' President and Chief Commercial Officer. "We continue to refine our program based on our regular interactions with the FDA, and the learnings from this study will allow us to continue to optimize the AI component of the Web App. Combined, we strongly believe in our approach and look forward to continuing development into the next indicated step for STENDRA^® (avanafil) in a non-prescription setting."

The Formative Human Factors study was conducted in a population of 30 consumers, including a cohort with limited literacy. The consumers were provided with five different use scenarios requiring correct demonstration of 194 different tasks using the Web App with no training or guidance. The study also included a proprietary AI interface that confirmed the identity of the consumer, a first-ever innovation for an Rx-to-OTC switch program.

About Petros Pharmaceuticals

Petros Pharmaceuticals, Inc. is committed to the goal of becoming a leading innovator in the emerging self-care market driving expanded access to key prescription pharmaceuticals as OTC treatment options. Currently, Petros is pursuing increased access for its flagship prescription ED therapy, STENDRA^® (avanafil), via potential OTC designation. If ultimately approved by the FDA for OTC access, STENDRA^® (avanafil) 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 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 informed 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 this, the FDA ordinarily requires a consumer tested OTC DFL. Such 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 its sale to Endo Pharmaceuticals, is an oral phosphodiesterase 5 (PDE5) inhibitor for the treatment of erectile dysfunction. STENDRA^® (avanafil) is not for use in women or children. It is not known if STENDRA^® (avanafil) 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^® (avanafil) 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^® (avanafil) (for example, more than three glasses of wine or three 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^® (avanafil) (50 mg, 100 mg, or 200 mg) due to side effects compared to 1.7% taking a placebo. STENDRA^® (avanafil) was designed and developed expressly for erectile dysfunction.

STENDRA is contraindicated for 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 three 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"). Doctors should 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.
