Summary

A Phase I, Open-Label, Randomized, Crossover Trial to Investigate the Relative Bioavailability of the 25 mg Dapivirine Vaginal Ring-004 inserted every 30 days and 100 mg Dapivirine Vaginal Ring-008 inserted for 90 days in Healthy Female Participants

Detailed description

IPM 054 is a Phase I, open-label, randomized, crossover trial to determine the relative bioavailability in plasma and vaginal fluid of two formulations of the dapivirine vaginal ring in HIV-negative women. The trial will compare the dapivirine concentrations achieved in plasma and vaginal fluid over all timepoints for each 90-day use period in a two-period, two-sequence, crossover design. Participants will be randomized to one of two treatment sequences (AB or BA). During two consecutive 90-day treatment periods, the participants will receive each of the following treatments according to their assigned treatment sequence. The treatment periods will be separated by a 28-day washout period. Treatment Sequence 1: • 25 mg dapivirine ring (Ring-004) for 90 days (replaced every 30 days) (Treatment A), followed by the 100 mg dapivirine ring (Ring-008) used continuously for 90 days (Treatment B) Treatment Sequence 2: • 100 mg dapivirine ring (Ring-008) used continuously for 90 days (Treatment B), followed by the 25 mg dapivirine ring (Ring-004) for 90 days (replaced every 30 days) (Treatment A)
