ArmTypeDescription
Substudy 01: Cohort 1: Bavtavirine 675 mg (High-Fat Meal)EXPERIMENTALParticipants receive a single dose of bavtavirine 675 mg tablet with a high-fat meal on Day 1. After assessments on Day 11 or upon early termination (ET), the participants initiate a regimen of B/F/TAF, or an alternative standard of care (SOC) antiretroviral (ART) regimen (example INSTI + NRTIs: dolutegravir (DTG)/abacavir (ABC)/3TC or DTG/3TC) up to Day 39.
Substudy 01: Cohort 2: Bavtavirine 1200 mg (Low-Fat Meal)EXPERIMENTALParticipants receive a single dose of bavtavirine 1200 mg tablet with a low-fat meal on Day 1. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 39.
Substudy 01: Cohort 3: Bavtavirine 900 mg (High-Fat Meal)EXPERIMENTALParticipants receive bavtavirine 900 mg tablet with a high-fat meal on Days 1 and 2. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 39.
Substudy 02: Cohort 1: GS-1720 450 mgEXPERIMENTALParticipants receive a single dose of GS-1720 450 mg tablet on both Days 1 and 2 in fasted condition. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 60.
Substudy 02: Cohort 2: GS-1720 150 mgEXPERIMENTALParticipants receive a single dose of GS-1720 150 mg tablet on both Days 1 and 2 in fasted condition. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 60.
Substudy 02: Cohort 3: GS-1720 30 mgEXPERIMENTALParticipants receive a single dose of GS-1720 30 mg tablet on both Days 1 and 2 in fasted condition. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 60.
Substudy 02: Cohort 4: GS-1720 900 mgEXPERIMENTALParticipants receive a single dose of GS-1720 900 mg tablet on both Days 1 and 2 in fasted condition. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 60.
Substudy 03: Cohort 1: GS- 6212 100 mgEXPERIMENTALParticipants receive GS-6212 100 mg tablet twice daily on Days 1 through 10. After assessments on Day 11 or upon ET, the participants initiate a regimen of B/F/TAF, or an alternative SOC ART regimen (example INSTI + NRTIs: DTG/ABC/3TC or DTG/3TC) up to Day 25.
