Daré Bioscience Announces Commencement of Phase 3 Study of Ovaprene®, an Investigational Hormone-Free Monthly Intravaginal Contraceptive

Ovaprene has the Potential to be the First FDA-Approved Monthly, Self-Administered, Hormone-Free Contraceptive Product

SAN DIEGO, Dec. 04, 2023 (GLOBE NEWSWIRE) — Daré Bioscience, Inc. (NASDAQ: DARE), a leader in women’s health innovation, today announced commencement of the Company’s pivotal Phase 3 clinical study of Ovaprene, an investigational hormone-free monthly intravaginal contraceptive.

The multi-center, single arm, non-comparative, pivotal Phase 3 clinical study of Ovaprene will evaluate its effectiveness as a contraceptive along with its safety and usability. The study aims to enroll sufficient participants across approximately 20 study sites in the U.S. to have approximately 250 participants complete approximately 12 months (13 menstrual cycles) of use, with updates on anticipated study completion expected as enrollment progresses. If successful, Daré expects the pivotal study to support marketing approvals of Ovaprene in the U.S. and other countries.

“While we’ve seen improvements in hormonal contraception over the last 20 years, many women need more options and innovation in non-hormonal contraceptive methods,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “Ovaprene is a hormone-free monthly contraceptive that has disruptive, first-in-category potential based on its convenient use that doesn’t require action at the time of intercourse and its unique mechanism of action, which based on the results of the pre-pivotal study, is expected to deliver efficacy approaching hormonal methods. Commencing our pivotal Phase 3 study marks an important milestone in the Ovaprene program as we strive to advance this innovative contraceptive option that women want and need.”

In July 2021, Daré entered into a Cooperative Research and Development Agreement (CRADA) with the U.S. Department of Health and Human Services, as represented by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health (NIH), to collaborate on the pivotal Phase 3 study of Ovaprene. The agreement gives Daré access to the contraceptive clinical trial expertise of the NICHD clinical trial network while also sharing the costs of the Phase 3 pivotal study with the NICHD.

In January 2020, Daré and Bayer announced an exclusive licensing agreement for U.S. commercial rights to Ovaprene. Under the agreement, Daré received an upfront payment and access to Bayer’s extensive clinical and market capabilities while retaining control over Ovaprene’s development and regulatory approval process. Bayer received the right to obtain exclusive rights to commercialize the product in the U.S. following completion of the pivotal clinical trial being undertaken by Daré.

“We’re excited about Daré’s announcement of commencement of the pivotal Phase 3 clinical trial for Ovaprene,” said Dr. Yesmean Wahdan, Vice President, US Medical Affairs Women’s Healthcare at Bayer. “It is extremely important that we continue to innovate and strive to address women’s unmet medical needs and wants, especially as it relates to contraceptive options.”

If Ovaprene is approved by the U.S. Food and Drug Administration (FDA), it could be the first monthly non-hormonal contraceptive product for women and a first-in-category option for women in the U.S. seeking a hormone-free, self-administered and monthly birth control method.

About Ovaprene^®

Ovaprene is an investigational hormone-free, intravaginal monthly product candidate currently in clinical development for pregnancy prevention. Ovaprene releases a locally acting, non-hormonal agent which impedes sperm motility and features a proprietary knitted polymer barrier to physically block sperm from entering the cervical canal.

Ovaprene completed a successful postcoital test (PCT) clinical study where, in all women and across all cycles evaluated, it prevented virtually all sperm from entering the cervical canal, a surrogate marker for contraceptive effectiveness.^{1, 2} The results from the PCT clinical study support continued clinical development of Ovaprene and its potential to be the first hormone-free, monthly contraceptive option for women.
