Brief Summary

A follow-on, open label trial to assess continued safety of and adherence to the Dapivirine(25mg) vaginal ring-004 in healthy, HIV-negative women

Detailed Description

Phase IIIb, multicenter follow-on open-label trial to evaluate the continued adherence to and safety of the DVR, inserted at monthly intervals by healthy, HIV negative women who had participated in the IPM 027 Phase III DVR trial. All women who participated in IPM 027 (NCT 01539226) and were HIV-negative at screening for IPM 032, were eligible.

Participants who provided written informed consent at screening were invited to undergo screening assessments for the trial. The Enrollment Visit had to occur within 45 days after the Screening Visit. Note: In the event that participation in IPM 027 was stopped prematurely and IPM 032 was activated at the RC, the IPM 027 Last Product Use Visit (LPUV) and the IPM 032 Screening and Enrollment Visits could be combined for participants who were eligible to enroll in IPM 032.

All participants received the DVR containing 25 mg dapivirine at the Enrollment Visit, and attended a visit at the RC, 1 month after enrollment. Following this visit, a participant could continue on a 3 monthly visit schedule, at the Investigator's discretion. Monthly visits could, however, be extended up to the first 3 months of participation. From then on, all participants needed to switch to a 3-monthly schedule. Once the 3-monthly trial visit schedule commenced, three rings were dispensed at each visit. One ring was self-inserted at the RC and two additional rings were dispensed for the participant to take home, or dispensing took place as arranged with the participant.

The protocol made provision for at least 12 months of DVR use (with the LPUV scheduled at Month 12), which could also have been extended. Participants could continue with ring use past Month 12 and the RCs could continue scheduling the 3-monthly visits as per the participant visit schedule. Exit Visits of participants who completed 12 months or more on the trial commenced in October 2017 and ended in January 2019. Participants who were still enrolled in the trial in October 2017 and those who had been enrolled at a later stage in the trial were scheduled to attend the Month 12 Visit, irrespective of their visit schedule assignments. Exit Visits were then scheduled as per protocol, ie, 1 to 2 months after the Month 12 Visit. Exit Visits were optional for participants who discontinued early from the trial.

Adherence assessments included analysis of dapivirine residual levels in returned used rings, correlation analysis of dapivirine residual levels with visual inspection of used rings, and self-reported acceptability and adherence.

The HIV-1 incidence and the occurrence of HIV-1 drug resistance were assessed using HIV rapid testing and genotyping, respectively.

Social and behavioral parameters were assessed qualitatively and quantitatively. Quantitative assessments included evaluation of the feasibility of 3-monthly follow-up visits and evaluation of the proportion of participants undergoing unscheduled HIV rapid tests (ie, in between the scheduled 3 monthly follow-up visits).

Safety assessments included adverse event (AE) reporting, safety laboratory assessments, pregnancy testing, physical examination, vital sign assessments, pelvic examination, sexually transmitted infection (STI) tests, cervical cytology, and assessments of social harms.

Throughout the trial, all participants received pre- and post-test HIV counseling, HIV/STI risk reduction counseling, and contraceptive, condom and vaginal ring adherence counseling.
