Study Endpoints

Primary Endpoints

Change in HIV status compared between arms (tenofovir vs placebo)
Baseline and monthly HIV testing for the duration of the study, an expected average of 18 months

The effectiveness of tenofovir against HIV infection will be measured by comparing the incidence of HIV in the tenofovir arm with that in the placebo arm

Secondary Endpoints

Change in incidence rate of deep epithelial disruption compared between arms
Baseline and monthly assessments for the duration of the study, an expected average of 18 months
To assess the impact of tenofovir gel on viral load
measured at the first visit post HIV infection, and again 3 months later
To assess tenofovir resistance in HIV seroconvertors in the trial
performed at the post-seroconversion visit

Tenofovir gelDRUGParticipants will be provided with a supply of single-use, pre-filled applicators according to their randomisation. While in the study, participants will be asked to apply a first dose of the assigned study product, 1% tenofovir gel, within 12 hours prior to coitus and insert a second dose as soon as possible within 12 hours after coitus. They will be advised to use only two doses of gel in a 24-hour period.
Placebo (Universal HEC placebo)DRUGParticipants will be provided with a supply of single-use, pre-filled applicators according to their randomisation. While in the study, participants will be asked to apply a first dose of the assigned study product, placebo gel, within 12 hours prior to coitus and insert a second dose as soon as possible within 12 hours after coitus.

What is Tenofovir used for in HIV Infections?

Tenofovir is a small molecule being studied for the prevention of HIV Infections. It is being developed as a candidate vaginal microbicide for HIV prevention. The drug is currently in Phase 2 clinical development and is not yet approved for this use.

What does Tenofovir target?

Tenofovir is a nucleotide reverse transcriptase inhibitor that works by blocking the activity of reverse transcriptase, an enzyme HIV needs to replicate. This mechanism is being evaluated in a Phase 2 trial for HIV prevention.

Who makes Tenofovir?

Tenofovir is being developed by United Therapeutics Corporation, which trades under the ticker UTHR. The company is conducting clinical trials to evaluate the drug as a vaginal microbicide for HIV prevention.

What phase is Tenofovir in?

Tenofovir is in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. One Phase 2 trial has been completed, and no active trials are currently listed.

What clinical trials is Tenofovir in?

Tenofovir has one completed Phase 2 trial, NCT00441298, titled 'Safety and Effectiveness Study of a Candidate Vaginal Microbicide for Prevention of HIV'. This randomized, double-blind, placebo-controlled trial enrolled 889 female participants in South Africa.

Is Tenofovir the same as Viread?

Tenofovir is the active ingredient in Viread, a medication used to treat HIV and hepatitis B. In this context, it is being studied as a vaginal microbicide for HIV prevention, which is a different formulation and use.
