Daré Bioscience Announces Initiation of Subject Enrollment in a Phase 1 Thermography Study to Support Pharmacodynamic and Pharmacokinetic Characterization of Sildenafil Cream, 3.6%


Phase 1 Thermography Study Quantitative Data Expected to Complement Patient Reported Outcome Data Collected in the Exploratory Phase 2b RESPOND At-Home Study

Topline Data for the Exploratory Phase 2b RESPOND Study Anticipated in 2Q-2023

SAN DIEGO, April 20, 2023 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ: DARE), a leader in women’s health innovation, and Strategic Science & Technologies, LLC (SST), a Cambridge, MA based novel topical drug delivery company, today announced initiation of screening and enrollment for a Phase 1 clinical study using thermography to assess the pharmacodynamic and pharmacokinetic characterization of Sildenafil Cream, 3.6% (Sildenafil Cream), a late-stage product candidate being developed as a potential new treatment for female sexual arousal disorder (FSAD). The quantitative pharmacokinetic and pharmacodynamic temperature data captured in a clinic setting in the study are expected to complement the patient reported outcome data collected in the ongoing Phase 2b RESPOND study, where the women use Sildenafil Cream in their home setting.

FSAD is the inability to reach or maintain a sufficient physical response to sexual stimulation and, of the various types of female sexual dysfunction disorders, FSAD is most analogous to erectile dysfunction (ED) in men. Sildenafil 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 topical cream formulation specifically designed to increase blood flow to the genital tissue in women. If successful, Sildenafil Cream has the potential to be the first FDA-approved treatment for FSAD.

“This Phase 1, single-dose, double-blind, placebo-controlled, 3-way crossover study will utilize thermography to assess the pharmacodynamics and pharmacokinetics Sildenafil Cream in comparison with versions of the cream without the active ingredient, sildenafil,” said Andrea Thurman, MD, Medical Director for Daré Bioscience. “The findings from this study, specifically the pharmacodynamic and pharmacokinetic data, are an important part of our comprehensive clinical development and regulatory plan for Sildenafil Cream and will add to our existing clinical and nonclinical data package to support the ongoing development program.”

During the thermography study, vulvar temperature, a surrogate for vulvar blood flow, will be recorded by thermography in a clinic setting. Increasing blood flow to the genital tissue, as Sildenafil Cream is designed to do, has the potential to improve genital arousal response and overall sexual experience for women. Unlike the oral formulations of PDE-5 inhibitors, Sildenafil Cream is designed to be applied locally to the vaginal tissue prior to sexual activity to facilitate vasodilation and increase blood flow directly to the genital tissue to improve the physical arousal response to address the lack of those genital arousal sensations commonly associated with FSAD.

“We are excited to announce that enrollment is underway in this important supplemental thermography study,” said Sabrina Martucci Johnson, President & CEO of Daré Bioscience. “This study has the potential to provide additional quantitative data regarding the ability of our cream formulation of the active ingredient sildenafil to increase genital blood flow, as assessed by vulvar temperature. These data are expected to complement forthcoming clinical findings from our Phase 2b RESPOND trial in preparation for a Phase 3 program.”

The Phase 1 thermography study of Sildenafil Cream is expected to enroll approximately 15 women and be completed in 2023.
