HIV Attachment Inhibitor to Treat Human Immunodeficiency Virus 1 (HIV-1) Infections

Maximum Decrease From Monotherapy Baseline in log10 Plasma HIV-1 RNA

Maximum decrease from monotherapy Baseline in log10 plasma HIV-1 RNA during monotherapy to assess the antiviral activity of temsavir following administration of selected doses of FTR administered orally to HIV-1-infected participants for 7 days. Baseline is defined as the last non-missing value on or before the date of first dose of study treatment. Change from Baseline was calculated as value at indicated time point minus Baseline value. The data for monotherapy nadir has been presented where nadir represents the maximum decrease from Baseline.

Time frame: Baseline and up to Day 8 of the monotherapy period

Percentage of Participants With Plasma HIV-1 RNA < 50 c/mL at Day 8 of the Monotherapy Period

Percentage of participants with plasma HIV 1 RNA \< 50 c/mL at Baseline of combination therapy was assessed to evaluate the antiviral activity of four doses of FTR. Baseline of combination therapy was the Day 1 of the combination therapy. Virologic success or failure was determined using the non-missing viral load value at Baseline of combination therapy. The assessment closest to the window target Study Day was used for the analysis. Only those participants with data available at the specified time points were analyzed.

Time frame: Up to Day 8 of the monotherapy period

Number of Participants With SAE and Discontinuation Due to AEs During Monotherapy Period

Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment or suspected transmission of an infectious agent via the study drug were categorized as SAE. AEs leading to discontinuation of study therapy were also reported as safety assessment.

Time frame: Up to Day 8 of the monotherapy period

Change From Monotherapy Baseline in Cluster of Differentiation (CD)4+ and CD8+ T-cell Counts During Monotherapy

Blood was collected and CD4+ and CD8+ cell count assessment was done by flow cytometery and was carried out at Baseline (Day 1) to evaluate the immunological activity of multiple doses of FTR. Baseline is defined as the last non-missing value on or before the date of first dose of study treatment and the values are absolute values. Change from Baseline was calculated as value at indicated time point minus Baseline value. Only those participants with data available at the specified time points were analyzed.

Time frame: Baseline and Day 8

Change From Monotherapy Baseline in CD4+ and CD8+ T-cell Proportion During Monotherapy

Blood was collected and CD4+ and CD8+ proportion assessment was done by flow cytometery and was carried out at Baseline (Day 1) to evaluate the immunological activity of multiple doses of FTR. Baseline is defined as the last non-missing value on or before the date of first dose of study treatment and the values are absolute values. Change from Baseline was calculated as value at indicated time point minus Baseline value. Only those participants with data available at the specified time points were analyzed.

Time frame: Baseline and Day 8

Percentage of Participants With Plasma HIV-1 RNA < 50 c/mL at Primary Study

Percentage of participants with plasma HIV 1 RNA \< 50 c/mL at Weeks 48 and 96 using the FDA snapshot algorithm was assessed to evaluate the antiviral activity. Treatment comparisons were not performed as this was an estimation study. Response rates were tabulated by treatment arm with exact Clopper-Pearson binomial 95 percentage CI. Virologic success or failure was determined by the last available HIV-1 RNA assessment while the participant was on-treatment within the snapshot window of the visit of interest.

Time frame: Weeks 48 and 96

Number of Participants With SAE and Discontinuation Due to AEs During Primary Study

Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment or suspected transmission of an infectious agent via the study drug were categorized as SAE. AEs leading to discontinuation of study therapy were also reported as safety assessment. Safety Population comprised of participants who received at least one dose of study treatment. Summaries of SAEs and AEs leading to discontinuation or withdrawal through Week X (where X = 48 or 96) included AEs with onset on or after the start of study treatment (i.e. study date of first study treatment intake) up to and including the end of the Week 48 and 96 visit snapshot window.

Time frame: Weeks 48 and 96

Change From Baseline in CD4+ T-cell Count

Blood was collected and CD4+ cell count assessment by flow cytometery was carried out at Baseline (Day 1), Weeks 24, 48 and 96 to evaluate the immunological activity of multiple doses of BMS-663068/GSK3684934. Baseline is defined as the last non-missing value on or before the date of first dose of study treatment and those values are absolute values. Change from Baseline was calculated as value at indicated time point minus Baseline value. Only those participants available at the specified time points were analyzed (represented by n=X in the category titles).

Time frame: Baseline and Weeks 24, 48 and 96

Number of Participants With Newly-emergent Genotypic Substitutions at Week 24
