The CAPRISA 008 trial is a two-arm, open-label, randomized controlled trial that is being conducted at the CAPRISA eThekwini and CAPRISA Vulindlela Clinics and their neighboring public sector family planning services in KwaZulu-Natal, South Africa. Up to 700 consenting sexually active, HIV-uninfected women aged 18 years and older who previously participated in an antiretroviral (ARV) prevention study will be enrolled and followed for a maximum 30 months. All women will be provided with 1% tenofovir gel but will be randomised to either receive their gel through a public sector family planning services with 2-3 monthly provision (intervention arm) or through the CAPRISA research clinics with monthly provision (control arm).
All women in the trial will be provided with the standard package of HIV prevention and reproductive health services. Participants in both study arms will be provided with a supply of single-use, pre-filled applicators of 1% tenofovir gel. While in the study, participants will be advised and supported to follow the CAPRISA 004 pre- and post-dosing strategy, namely BAT24, where the first dose of tenofovir gel is applied within 12 hours before anticipated coitus and a second dose as soon as possible but within 12 hours after coitus, with a maximum of two doses of gel in a 24-hour period.
The primary objective of this trial is to assess the effectiveness of an implementation model for tenofovir gel provision through family planning services.

Experimental: Intervention
1% tenofovir gel provision through a public sector family planning services with 2-3 monthly provision and monitoring and the use of QI methodology to promote reliable service delivery
|
Drug: 1% tenofovir gel
Participants will be randomized to receive 1% tenofovir gel through either:
|
|
Active Comparator: Control
monthly 1% tenofovir gel provision and monitoring through CAPRISA research clinics
|
Drug: 1% tenofovir gel
Participants will be randomized to receive 1% tenofovir gel through either:
|
- Mean number of returned used applicators [ Time Frame: monthly ]
Gel use is essential for the effectiveness of tenofovir gel in preventing HIV infection. The level of gel use was a strong predictor of effectiveness in the exploratory adherence analysis of the CAPRISA 004 trial. Gel use on its own and in relation to coitus were both predictors of the level of protection. Based on the CAPRISA 004 trial which demonstrated a correlation between the number of returned used applicators and the level of effectiveness against HIV infection, the primary endpoint is:
• Mean number of returned used applicators per participant per month
- Clinical and laboratory adverse events [ Time Frame: At each participant contact ]Any untoward medical occurrence experienced by an enrolled research participant, regardless of association with study product, will be recorded and managed accordingly
- HIV incidence rates [ Time Frame: at study completion ]
- Pregnancy rates [ Time Frame: Monthly ]
- Adherence [ Time Frame: Each scheduled study visit ]Self-reported adherence to the tenofovir gel dosing strategy as well as factors influencing gel use in relation to sexual activity, condom use, and intravaginal practices
- HIV viral load among HIV seroconverters [ Time Frame: At earliest timepoint after HIV positive result ]
- Tenofovir resistance among HIV seroconverters [ Time Frame: At study completion ]
- HSV-2 and HPV incidence rates [ Time Frame: At study completion ]
- Tenofovir levels [ Time Frame: At study completion ]Detection of tenovofir from vaginal samples
- Product acceptability [ Time Frame: At stucy completion ]Self-reported questionnaire on product acceptability
