Clinical Trial Summary

This study will evaluate the safety and efficacy of the human monoclonal antibody (mAb) VRC-HIVMAB060-00-AB (VRC01) in preventing HIV-1 infection in high-risk, HIV-uninfected women.


Description:

This study will evaluate the safety, tolerability, and efficacy of the VRC01 antibody in preventing HIV-1 infection in healthy women at high risk of HIV infection. Participants will be enrolled from a cohort of heterosexual women in sub-Saharan Africa. An equal number of study participants will be randomized to receive VRC01 mAb by IV infusion at a dose of 10 mg/kg or 30 mg/kg every 8 weeks, or to receive control infusions every 8 weeks. All participants will receive the VRC01 antibody or placebo by intravenous infusion at Weeks 0 (study entry), 8, 16, 24, 32, 40, 48, 56, 64, and 72. For 3 days following each infusion, participants will be asked to record and report any symptoms to study researchers. In addition to the infusion visits, participants will attend study visits at Weeks 4, 8 + 5 days, 12, 20, 28, 36, 44, 52, 60, 68, 76, 80, 84, 88, and 92. All study visits will include blood collection and HIV testing and counseling. Select study visits will include a medical history review, physical exam, urine collection, pregnancy testing for participants capable of becoming pregnant, risk reduction counseling, and an interview/questionnaire.

Primary Number of Participants With Early Infusion Discontinuation and Reasons for Discontinuation The number (percentage) of participants with early permanent discontinuation of infusions and their reason for discontinuation is summarized by treatment group. Includes all discontinuations documented on a study case report form. Measured through Week 72 (the last infusion visit).
Primary Incidence Rate of Early Infusion Discontinuation Incidence rate (95% CI) of early infusion discontinuation per 100 person years. Includes discontinuations documented on a study case report form and operational discontinuations defined as 20 consecutive weeks without participant contact. Discontinuations due to pregnancy, death, or HIV-1 infection are right-censored. Measured through Week 72 (the last infusion visit).
Primary Number of Participants With Documented HIV-1 Infection by the Week 80 Visit Prevention efficacy (PE) is measured as 1 minus the ratio (VRC01:control) of cumulative incidences of HIV-1 infection diagnosis between enrollment and the week 80 visit for assessment of the primary efficacy end point. Cumulative incidence was estimated with the Nelson-Aalen estimator for the cumulative hazard function, with stratification according to VRC01 dose and trial. Measured through Week 80.
Secondary Serum Concentration of VRC01 in Participants Assigned to Receive the mAb The pharmacokinetic analyses of VRC01 involved a subgroup of VRC01 recipients who had not acquired HIV-1 infection through the week 88 visit and were not likely to have used preexposure prophylaxis (on the basis of self-report or testing of dried blood-spot samples), randomly sampled among the trials and dose groups. Midpoint and trough concentrations are the participant-level median concentrations at the 4-week and 8-week postinfusion visits, respectively, across all 10 infusion intervals. Day 61 (5 days post infusion #2), Midpoint (4-weeks post infusion visits): Weeks 4, 12, 16, 28, 36, 44, 52, 60, 68, 76 and Trough (infusion visits): Pre dose at Weeks 0 (study entry), 8, 16, 24, 32, 40, 48, 56, 64, and 72.
Secondary VRC01 Clinical Lot Neutralization of Founder Viruses (IC80) The VRC01 80% inhibitory concentration (IC80) of acquired isolates was measured with the TZM-bl assay using the earliest available post-HIV-infection serum sample. Median and IQR are summarized immediately below, then the analysis of prevention efficacy was repeated for each of three prespecified categories of in vitro susceptibility of the infecting strain (IC80 less than 1 µg per milliliter, 1 to 3 µg per milliliter, or >3 µg per milliliter) with the use of the Aalen-Johansen estimator. Measured through Week 80.
Secondary VRC01 Serum Neutralization of Autologous Founder Viruses (ID50, ID80) Autologous titer (ID50, ID80) summaries, based on most sensitive virus, for first RNA+ samples from a subset of HIV-infected VRC01 recipients. Values below the limit of detection (less than 10) were set to NA. Summaries are only computed for the Pooled VRC01 arm. First RNA+ Sample detected from baseline up to Week 104.
