• Published data show that responses from 1-month and 24-hour recall patient reported outcome (PRO) instruments were similar and support that either method could be used to assess treatment efficacy in future clinical studies
• Longer recall intervals for PRO assessments are less burdensome to clinical study participants and may improve data collection compliance

SAN DIEGO, Aug. 13, 2024 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ: DARE), a leader in innovation for the health and wellbeing of women, today announced that additional data from the exploratory Phase 2b RESPOND clinical 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), has been published by The Journal of Sexual Medicine.

Publication Details

Johnson, et al. “Comparisons and correlations of 1-month recall vs 24-hour recall in patient-reported outcomes of an exploratory, phase 2b, randomized, double-blind, placebo-controlled clinical trial of sildenafil cream, 3.6% for the treatment of female sexual arousal disorder.” The Journal of Sexual Medicine, 2024 [Preprint] https://doi.org/10.1093/jsxmed/qdae086

“In this first-of-its-kind study in FSAD patients, we are very pleased to be able to share these data,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “Being able to show consistent results from patient reported outcome measures, regardless of whether she is recalling her experiences over the last month or the last day, provides important optionality as we consider how to clinically measure the impact of Sildenafil Cream on patients with FSAD.”

“This preplanned subset analysis was intended to investigate whether there were differences in outcomes when assessing arousal sensation on 24-hour vs 1-month PRO instruments,” said Dr. Annie Thurman, MD, FACOG, Medical Director at Daré Bioscience. “We were thrilled to see the strong correlation between the 24-hour recall eDiary and the 1-month recall instrument scores since the 1-month recall is significantly less burdensome for patients. With a condition that’s often dismissed and stigmatized, it's important to show that we can collect accurate data to assess efficacy of Sildenafil Cream in a way that’s easily manageable for patients.”

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 PRO measures, that best reflect that improvement. The patient population and the endpoints proposed to the U.S. Food and Drug Administration (FDA) for Phase 3 clinical development were those where Daré's exploratory post-hoc analyses of the Phase 2b study data showed that Sildenafil Cream demonstrated statistically significant and meaningful patient improvement. Daré previously announced a positive end-of-Phase 2 meeting with the FDA supporting advancement of Sildenafil Cream for the treatment of FSAD and continues to interact with the FDA on the development program for Sildenafil Cream as a treatment for FSAD.

As previously announced, efficacy data from the Phase 2b RESPOND study were published in Obstetrics & Gynecology, the official publication of the American College of Obstetricians and Gynecologists. The journal article, entitled “Preliminary Efficacy of Topical Sildenafil Cream for the Treatment of Female Sexual Arousal Disorder: A Randomized Controlled Trial,” can be found in the August 2024 issue of Obstetrics & Gynecology 144(2):p 144-152, and is available online here.

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.

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 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.
