Daré Bioscience, Inc. Announces Asset Transfer Agreement with Hydra Biosciences, Inc. for CatSper Contraceptive Target

CatSper antagonist has potential to provide pregnancy prevention via administration to either women or men as a novel, rapidly reversible, non-hormonal contraceptive

SAN DIEGO, July 16, 2018 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (NASDAQ:DARE), a clinical-stage, women’s biopharmaceutical company, today announced that it has entered into an asset transfer agreement with Hydra Biosciences, Inc. for the transfer of all of Hydra’s interest in certain intellectual property relating to Hydra’s CatSper ion channel target portfolio.

“CatSper represents a novel target for non-hormonal contraceptives for both men and women,” said Dr. David Friend, Chief Scientific Officer of Daré Bioscience. “Inhibiting CatSper prevents sperm from achieving the hyperactive motile state required for fertilization. With the acquisition of Hydra’s intellectual property surrounding the CatSper target, we can begin to identify therapies that could potentially provide a contraception solution that both men and women could utilize.  The potential for a first-in-class non-hormonal male or female contraceptive option aligns with the objectives of the foundations and government agencies that fund contraceptive research, and as such we will be pursuing grant funding to support the near-term research.”

“Hydra Biosciences is excited to be providing these assets to Daré, whose focus on women’s reproductive and sexual health makes it a natural fit for this novel approach to non-hormonal contraception,” said Russell Herndon, Hydra Biosciences President and CEO.  The sperm-specific ion channel, CatSper, was discovered by David Clapham, M.D., Ph.D., co-founder of Hydra Biosciences and currently the Vice President and CSO of the Howard Hughes Medical Institute. Initial studies carried out by Dr. Clapham and others suggest that pharmacological agents that block CatSper may serve as viable contraceptives. The target is well-validated with more than eight years of testing in mice that has demonstrated that genetic deletions of CatSper lead to complete male infertility, while female fertility is normal.  CatSper expression is confined to sperm, so a drug targeting CatSper could potentially be delivered to males or females, and one that is fast-acting would only be needed immediately prior to intercourse. Research suggests that CatSper based contraceptives would not affect sperm development, so resumption of full fertility could occur as soon as dosing stops.

“Our human clinical development activities remain focused on our lead programs Ovaprene® and Topical 5% Sildenafil Citrate Cream.  In parallel, we continue to screen, identify, and access technology that is highly differentiated and novel,” said Sabrina Martucci Johnson, President and CEO, Daré Bioscience. “With the CatSper intellectual property from Hydra Biosciences we are delivering on our commitment to advance unique innovation that addresses persistent unmet needs and that provides us with strategic optionality.”
