| Mean Change in Logarithm to the Base 10 (log10) HIV-1 Ribonucleic Acid (RNA) From Day 1 at Day 8-Randomized Cohort | Day 1 and Day 8 | Plasma samples were collected for analysis of HIV-1 RNA. Mean change in log10 HIV-1 RNA from Day 1 was estimated using analysis of covariance (ANCOVA) with log10 HIV-1 RNA change from Day 1 at Day 8 as dependent variable, treatment (fostemsavir or placebo) as an independent variable, and Day 1 log10 HIV-1 RNA as a continuous covariate. Change from Day 1 was calculated as value at Day 8 minus value at Day 1. The analysis was performed on Intent-to-Treat Exposed (ITT-E) Population which comprised of all randomized participants who received at least one dose of study treatment. Missing HIV-1 RNA values at Day 8 were imputed using (a) Day 1 Observation Carried Forward (D1OCF) for participants without a value during blinded treatment (i.e, imputing a zero change from Day 1) or (b) Last Observation Carried Forward (LOCF) for participants with an early value during blinded treatment before the Day 8 analysis visit window. |

| Number of Participants With Treatment-emergent Viral Genotypic Substitution of Interest in the GP160 Domain as a Measure of Genotypic Resistance-Randomized Cohort | Week 96 | Plasma samples were collected for emergent drug resistance testing. The number of participants with emergent viral genotypic substitutions of interest in the GP160 domain was identified by the next-generation sequencing (NGS) assay. Protocol defined virologic failure (PDVF) through Week 96 Population comprised of all participants with available phenotypic and genotypic resistance data meeting at the time protocol defined virologic failure (PDVF) was met. The criteria for PDVF was a) Confirmed, or last available prior to discontinuation, HIV-1 RNA \>=400 c/mL at any time after prior confirmed suppression to \<400 c/mL prior to Week 24 or Confirmed, or last available prior to discontinuation, \> 1 log10 c/mL increase in HIV-1 RNA at any time above nadir level where nadir is \>=40 c/mL prior to Week 24. b) Confirmed, or last available prior to discontinuation, HIV-1 RNA \>=400 c/mL at or after Week 24. |
| Number of Participants With Indicated Fold Change Ratio (FCR) Using the Monogram PhenoSense Entry Assay-Randomized Cohort | Week 96 | The phenotypic resistance to a drug is defined in terms of a fold change (FC) in IC50s, i.e., the ratio of the 50% inhibitory concentration (IC50) of the clinical isolate to the IC50 of a reference strain (wild type control). FCR was calculated as FC at PDVF divided by Baseline FC. The number of participants with the indicated change (ratio) in the two values at the time of PDVF is presented. FCR\<1 indicates that FC is smaller on-treatment than at Baseline. FCR \>3 indicates that on-treatment FC is 3 times greater than it was at Baseline. |

Outcome results
Mean Change in Logarithm to the Base 10 (log10) HIV-1 Ribonucleic Acid (RNA) From Day 1 at Day 8-Randomized Cohort
Plasma samples were collected for analysis of HIV-1 RNA. Mean change in log10 HIV-1 RNA from Day 1 was estimated using analysis of covariance (ANCOVA) with log10 HIV-1 RNA change from Day 1 at Day 8 as dependent variable, treatment (fostemsavir or placebo) as an independent variable, and Day 1 log10 HIV-1 RNA as a continuous covariate. Change from Day 1 was calculated as value at Day 8 minus value at Day 1. The analysis was performed on Intent-to-Treat Exposed (ITT-E) Population which comprised of all randomized participants who received at least one dose of study treatment. Missing HIV-1 RNA values at Day 8 were imputed using (a) Day 1 Observation Carried Forward (D1OCF) for participants without a value during blinded treatment (i.e, imputing a zero change from Day 1) or (b) Last Observation Carried Forward (LOCF) for participants with an early value during blinded treatment before the Day 8 analysis visit window.
Time frame: Day 1 and Day 8
Population: ITT-E Population. Participants with missing Day 1 HIV-1 RNA values were not analyzed.

Change From Day 1 in Cluster of Differentiation (CD) 4+ T-cell Count at Day 8-Randomized Cohort
CD4+ T- cell counts were assessed by flow cytometry. Mean change in CD4+ T- cell count from Day 1 at Day 8 was analyzed using one-way ANCOVA with change of CD4+ cell counts from Day 1 at Day 8 as the dependent variable, treatment (fostemsavir or placebo) as an in-dependent variable, and Day 1 CD4+ cell count as a continuous covariate. Change from Day 1 was calculated as value at Day 8 minus value at Day 1. Missing CD4+ cell count values at Day 8 were imputed using (a) D1OCF for participants without a value during blinded treatment (i.e., imputing a zero change from Day 1), or (b) LOCF for participants with an early value during blinded treatment before the Day 8 analysis visit window.
Time frame: Day 1 and Day 8
Population: ITT-E Population. Only those participants with data available at the specified time points were analyzed.

Change in CD4+ T- Cell Count Percentage From Day 1 at Day 8-Randomized Cohort
CD4+ T- cell counts were assessed by flow cytometry. Mean change in CD4+ T- cell count percentage from Day 1 at Day 8 was analyzed using one-way ANCOVA with change of CD4+ cell count percentage from Day 1 at Day 8 as the dependent variable, treatment (fostemsavir or placebo) as an independent variable, and Day 1 CD4+ cell count percentage as a continuous covariate. Change from Day 1 was calculated as value at Day 8 minus value at Day 1. Missing CD4+ cell count values at Day 8 were imputed using (a) D1OCF for participants without a value during blinded treatment (ie, imputing a zero change from Day 1), or (b) LOCF for participants with an early value during blinded treatment before the Day 8 analysis visit window.

Number of Participants With Indicated Fold Change Ratio (FCR) Using the Monogram PhenoSense Entry Assay-Randomized Cohort
The phenotypic resistance to a drug is defined in terms of a fold change (FC) in IC50s, i.e., the ratio of the 50% inhibitory concentration (IC50) of the clinical isolate to the IC50 of a reference strain (wild type control). FCR was calculated as FC at PDVF divided by Baseline FC. The number of participants with the indicated change (ratio) in the two values at the time of PDVF is presented. FCR\<1 indicates that FC is smaller on-treatment than at Baseline. FCR \>3 indicates that on-treatment FC is 3 times greater than it was at Baseline.
