Characteristics of Women Enrolled into a Randomised Clinical Trial of Dapivirine Ring for HIV-1 Prevention Nyaradzo Mgodi (MBChB, MMed) UZ-UCSF Annual Research Day 17 April 2015
Background • Over half of the 24.7 million people living with HIV-1 infection in sub-Saharan Africa in 2013 were women . • Unprotected heterosexual intercourse is the leading mode of HIV-1 transmission amongst women in this region. • Randomized trials of the antiretroviral agent tenofovir, formulated as oral pills or a topical vaginal gel, demonstrated efficacy in diverse at-risk populations worldwide. • However, in two trials among young women at risk for HIV-1 (VOICE and FEM-PrEP), adherence to daily tenofovir-containing pills or vaginal gels was very low and HIV-1 prevention efficacy could not be assessed.
Background • To quote Dr Hunidzarira from this morning “An HIV vaccine is the world’s best hope of ending HIV” • However, the world may be facing 20 million to 60 million new HIV infections in the 15 to 20 years it may take to develop and evaluate a vaccine that protects against HIV infection • In the interim, in order to protect women, development of potent, antiretroviral-based prevention products not requiring daily or coitally-dependent adherence is a priority. • Products like the Dapivirine Intra-vaginal ring
Dapivirine Intra-vaginal Ring • Dapivirine is a non-nucleoside reverse transcriptase inhibitor • Flexible ring made of an elastic silicone material • Measures 56 mm (about 2 ½”) in diameter and 7.7 mm (3/4”) thick • Designed for 28-day use • International Partnership for Microbicides (IPM) providing both the placebo ring and the dapivirine ring for the study
MTN-020 /ASPIRE A Multi-Center, Randomized, Double-Blind, Placebo-Controlled Phase III Safety and Effectiveness Trial of a Vaginal Matrix Ring ContainingDapivirinefor thePreventionof HIV-1 Infection in Women (ClinicalTrials.govnumberNCT01617096). AStudy to Prevent Infection with a Ring for Extended Use
MTN-020Objectives • Primary Objective – To determine the effectiveness and safety of dapivirine (25 mg) administered in a silicone elastomer vaginal matrix ring, when inserted once every 4 weeks, in preventing HIV-1 infection among healthy sexually active HIV-1 uninfected women • Secondary Objectives – To assess the acceptability of and adherence to the dapivirine vaginal ring, the frequency of drug resistance, and the relationship between drug concentrations and HIV-1 seroconversion
MTN-020 Design Randomized, placebo-controlled, double-blind, phase III trial • • Sexually active HIV-1 uninfected women who are non-pregnant, contracepting, and between 18-45 years of age HIV-1 testing, risk reduction, contraceptive provision, safety monitoring, pregnancy testing, product provision, adherence counseling Ring worn for 4 weeks, replaced every 28-35 days All participants receive a comprehensive HIV-1 prevention package including risk-reduction, condoms, treatment of STIs, and partner testing and referral services • • •
