  Purpose
IPM 012 is a double-blind, randomized, placebo-controlled phase I study conducted at one research center in Belgium among 36 healthy, HIV-negative women of 18-40 years of age, randomized in a 1:1:1 ratio to assess plasma, vaginal fluid and vaginal tissue levels and the pharmacokinetics of dapivirine when applying either Dapivirine Gel 4750, 0.05%, 2.5g or Dapivirine Gel 4789, 0.05%, 2.5g intravaginally for 11 days (1 day followed by a 3 day washout period and then 10 consecutive days); and to assess the safety of these gels as compared to the intravaginal HEC-based universal placebo gel.

Condition Intervention Phase
HIV Infections Drug: Dapivirine Gel 4750, 0.05%, 2.5g Drug: Dapivirine Gel 4789, 0.05%, 2.5g Drug: HEC-based Placebo Gel Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: A Double-Blind, Randomized, Placebo-Controlled Phase I Study to Compare the Pharmacokinetics of Intravaginal Dapivirine Gel 4750, 0.05%, 2.5g and Dapivirine Gel 4789, 0.05%, 2.5g Formulations and to Assess the Safety as Compared to the Intravaginal HEC-Based Universal Placebo Gel, 2.5g in Healthy HIV-Negative Women.
