The Food and Drug Administration (FDA) has accepted for Priority Review the New Drug Application (NDA) for DARE-BV1 for the treatment of bacterial vaginosis.

DARE-BV1 is an investigational thermosetting bioadhesive hydrogel containing clindamycin phosphate 2%. The product is designed as a one-time vaginally administered treatment. 

The NDA is supported by data from the multicenter, randomized, double-blind, placebo-controlled phase 3 DARE-BVFREE study (ClinicalTrials.gov Identifier: NCT04370548), which evaluated the efficacy and safety of DARE-BV1 in 307 patients aged 12 years and older diagnosed with bacterial vaginosis. Patients were randomly assigned 2:1 to receive a single vaginal dose of DARE-BV1 or placebo.

Treatment with DARE-BV1 was found to be statistically superior to placebo at the test of cure visit at day 21-30 in the intent-to-treat population (primary endpoint), with 70% of patients clinically cured compared with 36% for placebo. Clinical cure was defined as resolution of abnormal vaginal discharge associated with bacterial vaginosis, clue cells less than 20% of total epithelial cells on microscopy, and a negative 10% KOH “whiff” test.

In the per protocol population (n=148), DARE-BV1 demonstrated clinical cure rates of 77% at day 21 to 30 and 81% at day 7 to 14 compared with 43% and 30% for placebo, respectively. 

A Prescription Drug User Fee Act (PDUFA) target date of December 7, 2021 has been set for the application.
