Insights
The recent announcement by Daré Bioscience regarding the progression of Sildenafil Cream for FSAD into Phase 3 clinical trials is a significant milestone in the realm of women's health. The positive end-of-Phase 2 meeting with the FDA not only underscores the potential of this treatment but also highlights the proactive approach by the regulatory agency to address a condition with no current FDA-approved treatments.
From a medical research perspective, the decision to focus on a premenopausal FSAD-only population for the Phase 3 trials is noteworthy. This targeted approach may enhance the robustness of the efficacy data, as it isolates the variable of menopausal status, which can influence sexual function. Furthermore, the indication that a 12-week blinded treatment period may be acceptable, despite being shorter than the 24-week period suggested in previous FDA guidance, suggests a shift towards more streamlined trial designs that still meet efficacy assessment standards.
For stakeholders, the advancement of this cream represents a potential breakthrough in a market with high unmet needs. The emphasis on patient-reported outcomes as primary and secondary endpoints aligns with current trends in clinical research that prioritize patient-centric measures of success.
The progression of Sildenafil Cream into Phase 3 trials is a strong indicator of its commercial potential, given the estimated 10 million U.S. women affected by FSAD. This patient population represents a significant market opportunity for Daré Bioscience and its collaborator SST. The market impact of a successful product launch could be substantial, considering the lack of direct competition in the FDA-approved space for FSAD treatments.
Investors should note the strategic importance of the FDA's forthcoming feedback on primary and secondary endpoints for the Phase 3 trials. This information will be crucial in evaluating the potential for product registration and labeling, which are key factors in commercialization strategies. Moreover, the clarification on the safety database required for an NDA submission will provide insights into the regulatory hurdles that still need to be overcome before the product can reach the market.
It's also important to consider the broader implications of a successful treatment for FSAD on the women's health industry. A positive outcome could stimulate further research and development in the sector, potentially leading to a wave of innovation and investment in women's sexual health.
The financial implications of Daré Bioscience's announcement are multifaceted. On one hand, the transition into Phase 3 trials can be seen as a risk-reduction event for investors, as it indicates a higher likelihood of regulatory approval and market entry. On the other hand, the costs associated with Phase 3 development are substantial and the company's ability to finance these trials without undue dilution to shareholders or excessive debt is a critical factor to watch.
Given the absence of FDA-approved treatments for FSAD, the potential revenue for Sildenafil Cream could be significant. However, investors should also weigh the risks of clinical trial outcomes, regulatory decisions and market acceptance. The indication from the FDA that a shorter period of blinded treatment may be acceptable could potentially reduce trial duration and costs, thereby impacting the financial model for the drug's development.
Moreover, the focus on patient-reported outcomes in the Phase 3 trials may influence payer acceptance and reimbursement rates, which are crucial for the commercial success of any new drug. The ability to demonstrate not only clinical efficacy but also improvements in quality of life will be essential in justifying the product's value proposition to payers and patients alike.
There are no FDA-approved treatments for female sexual arousal disorder
SAN DIEGO, Jan. 31, 2024 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ: DARE), a leader in women’s health innovation, and its collaborator Strategic Science & Technologies, LLC (SST), a Cambridge, MA based novel topical drug delivery company, today announced the successful completion of an end-of-Phase 2 (EoP2) meeting with the U.S. Food and Drug Administration (FDA), supporting advancement of Sildenafil Cream,
Progressing Towards Sildenafil Cream Phase 3 Pivotal Study
The Company and the FDA aligned on key elements of the Phase 3 program to support a New Drug Application (NDA) filing, including confirming that:
- FSAD is acceptable as an indication.
- The trials can be conducted in a premenopausal FSAD-only population.
- 12-weeks of blinded treatment to assess efficacy may be acceptable, provided that the trials are adequately powered for efficacy assessment. This is a shorter period of blinded treatment than the 24 weeks recommended in 2016 draft FDA guidance for developing drugs for the treatment of low sexual interest, desire and/or arousal in women.
Additionally, the FDA indicated that feedback is forthcoming on the following:
- Primary and secondary patient reported outcome endpoints which will be used in Phase 3 pivotal trials and support potential product registration and labeling.
- Additional information on data that may be needed in an NDA submission to appropriately qualify any ingredient (other than sildenafil) for the vaginal route of administration.
Daré has also requested clarification on the safety database (size and duration of exposure) required for an NDA submission.
“We are pleased to have had a positive EoP2 meeting with the FDA as we work towards aligning on the Phase 3 program for Sildenafil Cream, which has the potential to address the significant unmet need associated with arousal disorder, which impacts approximately 10 million women in the U.S.,” said Dr. Andrew Goldstein, M.D., Medical Advisor for Daré Bioscience. “Given that there are currently no FDA-approved products for FSAD, we appreciate the FDA’s guidance and support and look forward to finalizing the Phase 3 protocol as we work to advance this product candidate into its first Phase 3 clinical study.”
The EoP2 meeting was supported by positive data from the exploratory Phase 2b RESPOND clinical study, which assessed arousal sensation and evaluated concerns related to difficulties with sexual arousal over a 12-week double-blinded treatment period. The Phase 2b study results identified the subgroup of patients most likely to benefit from therapy and achieve a meaningful improvement, and in those subjects demonstrated that Sildenafil Cream improved arousal sensation, desire, orgasm, as well as stress, guilt, and embarrassment about the sexual dysfunction. The Phase 2b data are being used to enrich the odds of a successful Phase 3 program. There are currently no FDA-approved therapies for the treatment of FSAD.
Building on 2023 Achievements, Looking at 2024
In addition to the significant progress with Sildenafil Cream, Daré continues to build on numerous milestones and achievements from 2023.
“Continued execution against our strategy throughout 2023 has positioned us well for 2024 as we accelerate our portfolio of novel investigational therapies, particularly those that have already demonstrated proof of concept and their potential to expand treatment options, improve outcomes, and enable convenience for women with some of the most persistent unmet needs,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “We remain focused on advancing our key pipeline programs, including our ongoing pivotal Phase 3 clinical study for Ovaprene, and continuing efforts toward our goal of advancing Sildenafil Cream into Phase 3 this year. Each of these programs – if approved – represents a potential first-in-category opportunity, and one of the most potentially disruptive therapeutic candidates for women in decades.”
About FSAD and Sildenafil Cream,
FSAD, as described in the DSM-IV, is a condition characterized as 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, and, of the various types of female sexual dysfunction disorders, FSAD is most 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.
