Brief Summary
The primary objectives of this study are to evaluate the safety and tolerability of escalating, multiple doses of vesatolimod (formerly GS-9620) in HIV-1 infected virologically suppressed adults on antiretroviral therapy (ART) and to evaluate the virologic effect of vesatolimod as measured by changes in plasma HIV-1 RNA.

Outcome Measures
Primary Outcomes (2)
Percentage of Participants Experiencing Treatment-Emergent Serious Adverse Events (SAEs) and Any Treatment-Emergent Adverse Events (AEs).
For Cohorts 1 to 3: First dose date up to 71 days plus 30 days; For Cohorts 4 to 6: First dose date up to 127 days plus 30 days; For placebo: First dose date up to 71 days plus 30 days or first dose date up to 127 days plus 30 days
Maximum Change From Baseline in Plasma Log10 HIV-1 RNA at Any Postdose Timepoint
The maximum change from baseline in plasma Log10 HIV-1 RNA refers to the maximum change at any postdose timepoint up to Day 81 or Day 134 for placebo, Day 81 for Cohorts 1 to 3, and Day 134 for Cohorts 4 to 6.
For Cohorts 1 to 3: Baseline to Day 81; For Cohorts 4 to 6: Baseline to Day 134; For placebo: Baseline to Day 81 or Baseline to Day 134

Interventions
Tablet(s) administered orally once every 2 weeks
Participants' current ARV regimen must be used in accordance with their prescribing information and may include the following: nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), raltegravir, dolutegravir, rilpivirine, and maraviroc.
Eligibility Criteria
You may qualify if:
- HIV-1 infection
- Aged ≥ 18 years at Pre-baseline/Day -13
- On antiretroviral (ARV) treatment for ≥ 12 consecutive months prior to Pre-Baseline/Day -13
- The following agents are allowed as part of the current ARV regimen: NRTIs, raltegravir, dolutegravir, rilpivirine, and maraviroc
- The following agents are NOT allowed as part of the current ARV regimen: HIV protease inhibitors (including low dose ritonavir), cobicistat-containing regimens, elvitegravir, efavirenz, etravirine, and nevirapine
- A change in ARV regimen ≥ 45 days prior to baseline/Day 1 for reasons other than virologic failure (eg, tolerability, simplification, drug-drug interaction profile) is allowed
- Plasma HIV-1 RNA \< 50 copies/mL at screening
- Documented plasma HIV-1 RNA levels \< 50 copies/mL (according to the local assay being used) for ≥ 12 months preceding the screening visit (measured at least twice using a licensed assay with a lower limit of quantitation of at least 40 copies/mL)
- Unconfirmed virologic elevations of ≥ 50 copies/mL (transient detectable viremia, or "blip") prior to screening are acceptable. (If the lower limit of detection of the local HIV-1 RNA assay is \< 50 copies/mL, the plasma HIV-1 RNA level cannot exceed 50 copies/mL on two consecutive HIV-1 RNA tests)
- If ART regimen is changed ≥ 60 days prior to Pre-Baseline/Day -13, plasma HIV-1 RNA \<50 copies/mL at Pre-baseline/Day -13 visit is required
- No documented history of resistance to any components of the current ARV regimen
- Availability of a fully active alternative ARV regimen, in the opinion of the Investigator, in the event of discontinuation of the current ARV regimen with development of resistance
- Hgb ≥ 11.5 g/dL (males) or ≥ 11 g/dL (females)
- White blood cells (WBC) ≥ 4,000 cells/μL
- Platelets ≥ 150,000/mL
- +6 more criteria
You may not qualify if:
- Hepatitis B surface antigen (HBsAg) positive
- Positive anti-HBs antibody and negative HBsAg results are acceptable
- Hepatitis C antibody (HCVAb) positive
- Positive anti-HCV antibody and negative HCV polymerase chain reaction (PCR) results are acceptable
- Documented history of pre-ART CD4 nadir \< 200 cells/µL
- Unknown pre-ART CD4 nadir is acceptable
- A new AIDS-defining condition diagnosed within 90 days prior to screening
- Acute febrile illness within 35 days prior to pre-baseline/Day -13
