DARE-BV1 demonstrated an 86% clinical cure rate in evaluable subjects at the test-of-cure visit (Day 7-14) after a single administration in an investigator-initiated proof of concept study

SAN DIEGO, Dec. 18, 2019 (GLOBE NEWSWIRE) -- Daré Bioscience, Inc. (DARE), a leader in women’s health innovation, today announced that the U.S. Food and Drug Administration (FDA) has cleared its investigational new drug (IND) application for DARE-BV1, its novel thermosetting bioadhesive hydrogel containing 2% clindamycin phosphate being developed for one-time vaginal administration for the treatment of bacterial vaginosis (BV), a common but difficult to treat vaginal infection estimated to affect more than 20 million women in the United States.1

With the IND clearance from the FDA, Daré can commence the planned Phase 3 clinical study of DARE-BV1 in approximately 220 women in 2020 to support the New Drug Application (NDA) submission. Based on discussions with the FDA, the Phase 3 study will include a placebo control and assess the primary endpoint of clinical cure of BV (defined as resolution of specified clinical signs and symptoms from baseline visit) at the test-of-cure visit to occur 21 to 30 days after enrollment in the study, or the Day 21-30 visit. If this single Phase 3 study and the nonclinical studies that Daré plans to conduct in parallel with the Phase 3 study are successful, Daré intends to file the NDA following the completion of this Phase 3 study.

“With the potential to demonstrate a higher clinical cure rate than the current FDA-approved vaginally-administered treatments and its single application one-and-done dosing regimen, DARE-BV1 could disrupt the bacterial vaginosis market. This announcement marks another important milestone for Daré, becoming the third program in our portfolio where we have achieved a meaningful clinical or regulatory objective this quarter,” said Sabrina Martucci Johnson, President & CEO of Daré Bioscience. “Earlier in the quarter, we announced the successful completion of a clinical study of Ovaprene, supporting its potential to be the first hormone-free, monthly contraceptive option for women and continued development toward premarket approval pending the successful commencement and completion of a pivotal contraceptive effectiveness and safety trial. More recently, we announced the conclusion of a Type C meeting with the FDA and alignment with the agency on the study design, including the primary endpoints and the patient reported outcome instruments, for our Phase 2b study of Sildenafil Cream, 3.6% for the treatment of female sexual arousal disorder, a condition for which there are currently no FDA-approved products.”

Bacterial vaginosis (BV) is the most common cause of vaginitis worldwide.2 While there are a number of treatment options for women diagnosed with BV, most options have relatively low clinical cure rates (37-68%), which may be one of the key drivers of recurrence rates. It is estimated that as many as 50% of women treated for BV will experience a recurrence within twelve months of their treatment.3

Earlier this year, Daré announced that DARE-BV1 had been granted Qualified Infectious Disease Product (QIDP) designation by the FDA for the treatment of BV in women. QIDP designation creates incentives for the development of antibacterial and antifungal drug products that treat serious or life-threatening infections. The primary incentive is a five-year exclusivity extension added to any exclusivity for which a QIDP qualifies upon FDA approval and makes the product candidate eligible for Fast Track designation and Priority Review.

BV has been associated with serious health issues, including preterm births, pelvic inflammatory disease, increased susceptibility to sexual transmitted infections (including HIV infection) and other chronic health problems.4 It is estimated that BV is present in at least 15% of the sexually active population making it more common than urinary tract infections and many times more common than the Trichomonas vaginalis infection and vulvovaginal candidiasis.5
