This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- Ovaprene
- Announced Date:
- May 12, 2026
- Indication:
- Intravaginal Contraceptive
Announcement
Daré Bioscience, Inc. announced positive interim safety and efficacy results from its ongoing Phase 3 clinical trial evaluating the contraceptive effectiveness, safety and acceptability of Ovaprene®, the company's investigational monthly, hormone-free intravaginal contraceptive.
AI Summary
Daré Bioscience said its ongoing Phase 3 study of Ovaprene®, a monthly, hormone-free vaginal birth control method, has shown positive interim safety and efficacy results. An independent Data Safety Monitoring Board reviewed the trial’s safety data and recommended that the study continue without any changes. This was the second time the board gave a positive review, following a similar earlier review.
The company said the results support Ovaprene’s potential as a first-of-its-kind contraceptive option for women seeking effective birth control without hormones. Daré’s CEO said many women want new hormone-free choices, and Ovaprene could help meet that need. The company now plans to keep moving toward the study’s final endpoint analysis as the trial continues.

- Announced Date:
- December 1, 2025
- Indication:
- Intravaginal Contraceptive
Announcement
Daré Bioscience, Inc. announced that all rights to Ovaprene®, the company's first-in-category, investigational, hormone-free monthly intravaginal contraceptive, will be returned to Daré by Bayer HealthCare LLC as a result of Bayer electing to terminate the license agreement between the parties as part of a strategic prioritization.
AI Summary
Daré Bioscience announced that Bayer HealthCare will return all rights to Ovaprene after electing to terminate their license agreement as part of a strategic prioritization. The termination becomes effective in February 2026. Because the Phase 3 program is being funded with non-dilutive grants, the return gives Daré full control of this late-stage, hormone-free monthly intravaginal contraceptive and lets the company steer the remainder of development and commercialization efforts.
Daré highlighted positive interim Phase 3 data from July 2025 showing consistent safety, tolerability, and pregnancy rates in line with expectations. Consolidating global rights under Daré increases strategic flexibility to seek partnerships, alternative commercialization models, or to retain greater long-term economics. The company expects Phase 3 enrollment to finish in 2026 and the trial continues with previously announced external grant support, including funding from the Gates Foundation. Daré says the move strengthens its position with a differentiated asset in a large market with unmet need.

AI Summary
The U.S. Food and Drug Administration has cleared Daré Bioscience’s Investigational New Drug (IND) application for DARE-HPV, an investigational proprietary fixed‑dose formulation of lopinavir and ritonavir in a soft‑gel vaginal insert. This clearance allows Daré to begin a planned Phase 2 clinical study to evaluate DARE‑HPV as a potential treatment for persistent high‑risk human papillomavirus (HPV) infection. DARE‑HPV is being developed as a non‑surgical, localized, self‑administered therapy aimed at clearing persistent high‑risk HPV.
HPV causes 99% of cervical cancer cases in the United States, and there are currently no FDA‑approved drug treatments for HPV infection. By targeting the virus itself rather than waiting for cells to change, DARE‑HPV could change how cervical disease is prevented. The Phase 2 study will assess safety and antiviral activity in women with persistent high‑risk HPV. The program is supported by a $10 million ARPA‑H contract, $6.5 million of which has been received, and Daré is preparing to start the trial in 2026.
