Daré Bioscience Announces Publication in Contraception of Positive Efficacy and Safety Findings from a Pre-Pivotal Postcoital Test Study of Ovaprene

an Investigational Hormone-Free Monthly Intravaginal Contraceptive - Seite 2

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 NICHD’s Contraceptive Clinical Trial Network while also sharing the costs of the Phase 3 pivotal study with 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 if Bayer, in its sole discretion, pays Daré $20 million. In addition, Daré may receive from Bayer up to $310 million in commercial milestone payments, plus double-digit, tiered royalties on net sales.

If Ovaprene is approved by the FDA, it could be the first monthly hormone-free contraceptive product for women and a first-in-category option for women 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 to impede 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 FDA-approved hormone-free, monthly contraceptive option for women.
