Human monoclonal antibodies (mAbs) may have the potential to treat HIV infection by preventing the spread of the virus. This study will evaluate an experimental mAb known as VRC-HIVMAB060-00-AB (VRC01). The purpose of this study is to evaluate the safety and therapeutic efficacy of VRC01, when administered during analytic treatment interruption (ATI), in adults who began antiretroviral therapy (ART) during early acute HIV infection.
The study will enroll participants from the RV 254 study who were diagnosed during early acute HIV infection and who have been on ART. At study entry, participants will stop taking their antiretroviral (ARV) medications. They will be randomly assigned to receive an intravenous (IV) infusion of VRC01 or placebo at Weeks 0 (study entry), 3, 6, 9, 12, 15, 18, 21, and 24. For 7 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 follow-up visits for 48 weeks. Study visits may include physical examinations, blood collection, and urine collection. Neurocognitive testing will take place at select study visits. Some participants may take part in optional study procedures including mucosal secretion collection, MRI brain scan, colon biopsy, lymph node biopsy, leukapheresis, and lumbar puncture.
Study staff will monitor participants' HIV throughout the study, and participants will end their participation in the study and restart their ARV medications, if needed.

Participants will receive an intravenous (IV) infusion of 40 mg/kg of VRC01 at Week 0 and every 3 weeks until Week 24 or until criteria for resumption of ART are met.
40 mg/kg; administered IV
Other Name: VRC-HIVMAB060-00-AB
Placebo Comparator: Placebo for VRC01
Participants will receive an IV infusion of placebo at Week 0 and every 3 weeks until Week 24 or until criteria for resumption of ART are met.
Biological: Placebo for VRC01
Sodium Chloride for Injection 0.9%, USP; administered IV
- Number of Participants With Serious Adverse Event [ Time Frame: Measured up to 10 weeks after last infusion of VRC01 or placebo ]Participants were monitored for up to 10 weeks after the last infusion of VRC01 or placebo
- Number of Participants With Sustained Virologic Suppression [ Time Frame: Measured through 24 weeks after ATI ]Number of participants who sustained virologic control (HIV RNA <50 copies/mL), without indication for ART resumption at week 24.
- Time to Viral Rebound After Cessation of ART [ Time Frame: Measured from Baseline ATI through ART resumption. ]
This is the days from Analytic Treatment Interruption (ATI) to:
- HIV RNA >= 20 copies/mL.
- HIV RNA >= 1000 copies/mL
- Level of Rebound Viremia After Cessation of ART [ Time Frame: Measured from Baseline ATI through ART resumption. ]This is the HIV-1 RNA levels (copies/mL) at first detection and ART resumption.
- Time to ART Resumption for Any Reason After Cessation of ART [ Time Frame: Measured from Baseline ATI through ART resumption. ]This is the days from ATI to ART resumptions.
- Number of Participants With Detectable HIV-1 RNA Via Single Copy Assay [ Time Frame: Measured from Baseline ATI through ART resumption. ]This is number of participants who had detectable HIV-1 RNA via the ultrasensitive single copy assay prior to detectability on the routine assay.
- Change in CD4+ T Cell Count From ATI to ART Resumption [ Time Frame: Measured from Baseline ATI through ART resumption ]This is change in CD4+ T cell count from ATI to ART resumption.
- Total HIV DNA in the Peripheral Compartment [ Time Frame: Measured from ATI through 6 months after ART resumption ]This is total HIV DNA levels at baseline ATI, ART resumption and 6 month after ART resumption
- Number of Participants Hospitalized. [ Time Frame: Measured up to 10 weeks after the last infusion of VRC01 or placebo ]Participants were monitored for up to 10 weeks after the last infusion of VRC01 or placebo
- Number of Participants With Acute Retroviral Syndrome (ARS) [ Time Frame: Measured from Baseline ATI through ART resumption. ]This is the number of participants who have developed during ATI.
- Neuropsychological Battery Performance [ Time Frame: Measured from Baseline ATI through ART resumption. ]This is a NPZ-4 score,a 4-test NP battery evaluated fine motor function/manual dexterity [Grooved Pegboard test (GP), non-dominant hand], psychomotor speed [Color Trails 1 (CT1), Trail Making A (TM)], and executive function/set shifting [Color Trails 2 (CT2)]. Individual test raw scores were converted to z-scores. Z-scores range from -3 standard deviations up to +3 standard deviations. Higher scores indicate better test performance and lower cognitive impairment.
- Computed Score on the Control and Attention Task (i.e., Flanker Task) [ Time Frame: Measured from Baseline ATI through ART resumption. ]The Flanker is a measure of executive function, specifically tapping inhibitory control and attention.The scores range from 0 to 10. A higher scores indicate higher levels of ability to attend to relevant stimuli and inhibit attention from irrelevant stimuli.
