FSAD is clinically analogous to erectile dysfunction in men.To date, there are no FDA-approved pharmacological treatments for FSAD; Daré’s Sildenafil Cream has the potential to receive the first FDA approval for FSAD. Market research estimates approximately 10 million women in the U.S. are distressed from experiencing symptoms associated with FSAD and are actively seeking solutions to improve their condition. SAN DIEGO, Dec. 16, 2024 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ: DARE), a leader in innovation for the health and wellbeing of women, and its collaborator Strategic Science & Technologies, LLC (SST), a Cambridge, MA based novel topical drug delivery company, today announced plans for a Phase 3 study of Sildenafil Cream, 3.6%, an investigational topical cream formulation of sildenafil being developed as an on-demand treatment for female sexual arousal disorder (FSAD), reflecting U.S. Food and Drug Administration (FDA) feedback for safety and efficacy evaluations to support the indication of treatment of FSAD in premenopausal women. “We have appreciated the FDA’s collaboration on the Phase 3 design for this novel therapeutic indication for women,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “While increased attention has been focused on female sexual dysfunctions over the past several years, no pharmacologic options have yet been FDA approved for FSAD, a condition which significantly compromises a woman's ability to have a pleasurable sexual experience. We are excited about the potential for Daré’s Sildenafil Cream formulation to address this critical unmet need in women's sexual health, and that there is a clear path forward on how to evaluate the safety and efficacy of this novel formulation of the same active in Viagra® so that women may have access to a safe, effective and ‘on demand’ solution to difficulties with sexual arousal allowing for a more intense and enjoyable sexual experience.” As an immediate next step, Daré will submit the protocol and statistical analysis plan for an adequate and well-controlled Phase 3 clinical study, reflecting the FDA’s recommendations, to the FDA in the first quarter of 2025, and is targeting mid-2025 for commencement of the Phase 3 study. A second confirmatory Phase 3 study will be required to support the New Drug Application (NDA) submission. With Sildenafil Cream’s potential to be the first FDA-approved product for FSAD, Daré is poised to create a new market category within the female sexual dysfunction space. About FSAD and Sildenafil Cream, 3.6% FSAD, as described in the DSM-IV, is a condition characterized primarily by a persistent or recurrent inability to attain or maintain sufficient genital arousal (an adequate lubrication-swelling response) during sexual activity, frequently resulting in distress or interpersonal difficulty. FSAD is clinically analogous to erectile dysfunction (ED) in men. As with ED in men, FSAD is associated with insufficient blood flow to the genitalia. To date, there are no FDA-approved pharmacological treatments for FSAD. Sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor, is the active ingredient in a tablet for oral administration currently marketed under the brand name Viagra® for the treatment of ED in men. Sildenafil Cream, 3.6% (Sildenafil Cream) is an investigational, proprietary cream formulation of sildenafil designed for topical administration to the vulvar-vaginal tissue on demand to increase genital blood flow and provide improvements in the female genital arousal response, while avoiding systemic side effects observed with oral formulations of sildenafil. Market research suggests that 16% of women in the U.S. ages 21 to 60, or approximately 10 million women, are distressed from experiencing symptoms associated with FSAD, including lack of or low sexual arousal, and are actively seeking solutions to improve their condition. In comparison, the prevalence of complete ED in men is estimated to be about 5% of men at age 40, increasing to about 15% at age 70. Completed Sildenafil Cream, 3.6% Exploratory Phase 2b RESPOND Study The exploratory Phase 2b RESPOND study was specifically designed to identify the patient population that experienced the most meaningful improvement from Sildenafil Cream and the questions to ask them, or the patient-reported outcome (PRO) measures, that best reflect that improvement, to inform Phase 3 design for this potential first-in-category treatment for FSAD. As previously announced, safety and efficacy data from the Phase 2b RESPOND study have been published in The Journal of Sexual Medicine and Obstetrics & Gynecology, respectively: Thurman, et al. “Safety of topical sildenafil cream, 3.6% in a randomized, placebo-controlled trial for the treatment of female sexual arousal disorder.” The Journal of Sexual Medicine, 2024, 1-7. https://doi.org/10.1093/jsxmed/qdae089Johnson, et al. “Preliminary Efficacy of Topical Sildenafil Cream for the Treatment of Female Sexual Arousal Disorder: A Randomized Controlled Trial.” Obstetrics & Gynecology, 144(2):p 144-152, August 2024. DOI: 10.1097/AOG.0000000000005648 Planned Phase 3 Study Consistent with the previously completed Phase 2b RESPOND study, the planned Phase 3 study will include a 12-week double-blind treatment period evaluating Sildenafil Cream compared to placebo cream. Analogous to previously approved treatments for ED in men, the Phase 3 study will have co-primary efficacy endpoints. Clinical programs for approved ED products have evaluated three co-primary endpoints specific to sexual arousal. For FSAD, the FDA has recommended a clinical program consistent with the Phase 2b RESPOND study, where only two co-primary endpoints were included – one assessing arousal sensations and one assessing associated distress, where distress is included as a co-primary endpoint to support the treatment effect of Sildenafil Cream. The Sildenafil Cream Phase 3 study will include the same co-primary endpoints for arousal sensations and associated distress used in the Phase 2b RESPOND study. In addition, secondary endpoints to assess improvement in orgasm, desire, and distress and interpersonal difficulties will be included, as they were in the Phase 2b RESPOND study. Claims of treatment benefit of the symptoms (but not the indications of Hypoactive Sexual Desire Disorder or Female Orgasmic Dysfunction) can be pursued via clear endpoint definition and formal statistical testing with adjustment for multiplicity, including a plan to control the type 1 error rate, which Daré plans to include in its protocol and statistical analysis plan for the Phase 3 study.
