Study Endpoints

Primary Endpoints

Kaplan-Meier Estimate of HIV-1 Infection Rate in Intent to Treat Population
42 Months

HIV-1 infection rate. Detection of HIV-1 infection was defined according to the HIV diagnostic algorithm utilizing serologic and nucleic acid technologies. Incidence of HIV infection was compared in the vaccine and placebo-recipient groups.

Vaccine Efficacy as Determined by Acquisition of Infection in the Per-protocol Population
42 Months

Cumulative Number of HIV Infections. Detection of HIV-1 infection was defined according to the HIV diagnostic algorithm utilizing serologic and nucleic acid technologies. Incidence of HIV infection was compared in the vaccine and placebo-recipient groups.

Changes in HIV-1 Viral Load in Volunteers Developing HIV Infection During the Trial for the MITT Population
42 months

Log10 HIV-1 viral loads for diagnostic specimens for subjects with post-HIV infection. The trial quantitated HIV plasma viral load at the time of diagnosis and through the remainder of the follow-up period. Peri infection results were compared in vaccine and placebo recipients who became HIV-infected during the trial.
