Dare Bioscience, Inc., formerly Cerulean Pharma Inc., is a healthcare company. The Company is focused on the development and commercialization of products in women’s reproductive health. Its lead product candidate is Ovaprene, a clinical stage, non-hormonal contraceptive ring. The Company is developing Ovaprene to provide protection over multiple weeks of use and require no intervention at the time of intercourse. Ovaprene has a custom intravaginal ring design, with a permeable mesh in the center of the ring that creates a partial barrier to sperm, and a mechanism to release locally acting spermiostatic agents through the ring. The combination of these two complementary approaches produces attractive contraceptive efficacy outcomes that are consistent with the effective barrier option, the diaphragm, and short-acting hormonal options, such as oral pill, patches and vaginal ring.
