Petros Pharmaceuticals, Inc. announced completion of a pivotal label comprehension study (LCS). Using FDA guidance provided to the company in 2022, the LCS is expected to satisfy a critical step in the organization's progress towards a possible non-prescription version of STENDRA, the Company's prescription erectile dysfunction drug. Akin to a Phase 2a study in clinical development sequencing, this study's purpose is to evaluate the nonprescription Drug Facts Label and consumer comprehension of key guidelines for safe and appropriate use.

The study required a consumer to read the Drug Facts Label, then answer a series of use-case scenario questions during a live virtual interview. Powered by a 95% Confidence Interval, the study protocol included approximately 29 primary endpoint questions designed to evaluate the consumer's understanding of the particular use-case with target thresholds ranging from 90% to 95% comprehension respectively. Results showed significant comprehension among the 480 subjects.

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. The Company recently undertook a relaunch of Stendra®, generating gross revenues of approximately $30 million in 2019.

Petros intends to accelerate the relaunch of Stendra® with a well-funded commercial organization and refocused strategy.
