AI Summary
Petros Pharmaceuticals, Inc. announced new results from an additional analysis of its pivotal study aimed at facilitating FDA-approved over‐the-counter access for STENDRA® (avanafil). The analysis focused on the effectiveness of the company’s proprietary Web App, which includes a clinically validated diagnostic questionnaire, in helping consumers accurately self-select the medication. The updated findings showed a point estimate of 94.9% and a lower bound of 91.51% for correct self-selection—improvements of 4.3% and 5.14% over earlier figures.

Announcement
Petros Pharmaceuticals, Inc. announces results of the first of a series of pivotal studies aimed at facilitating FDA-approved OTC access of STENDRA® (avanafil) for consumers.
AI Summary
Petros Pharmaceuticals, Inc. announced encouraging results from the first pivotal study aimed at supporting FDA-approved over‐the‐counter (OTC) access for its ED treatment, STENDRA® (avanafil). The study compared a new Web App Technology with the traditional Drug Facts Label (DFL) to help consumers decide if the medication was right for them. Results showed that 90.6% of participants using the Web App made the correct self-selection decision, compared to only 57.3% using the DFL alone. This significant improvement, especially among high-risk nitrate users, supports the company’s approach to meeting the FDA’s Additional Conditions for Nonprescription Use criteria. Petros is now working closely with the FDA and plans to conduct further pivotal tests, including an ‘actual use’ trial, as part of its pathway to switch STENDRA from prescription-only to OTC availability.
