Study Description

Brief Summary

The primary objectives of this study are:

Part A: To evaluate the short-term antiviral activity of lenacapavir (formerly GS-6207) with respect to the maximum reduction of plasma HIV-1 RNA (log10 copies/mL) from Day 1 through Day 10 compared to placebo in HIV-1 infected adults who are antiretroviral treatment naive or are experienced but capsid inhibitor (CAI) naive.

Part B: To evaluate the short-term antiviral activity of tenofovir alafenamide (TAF) with respect to the maximum reduction of plasma HIV-1 RNA (log10 copies/mL) from Day 1 through Day 10 in HIV-1 infected adult subjects who are antiretroviral treatment naïve or are experienced but without resistance to TAF.

    Outcome Measures

    Primary Outcome Measures

    1. Part A and Part B: Maximum Reduction From Day 1 (Baseline) Through Day 10 in Plasma HIV-1 RNA [Day 1 through Day 10]

      Maximum reduction is defined as the minimum of change from baseline in plasma HIV-1 RNA (i.e. smallest change in HIV-RNA from baseline).

    Secondary Outcome Measures

    1. Part A and Part B: Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs) [Day 1 through 225 days]

      An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which does not necessarily have a causal relationship with the treatment. An AE could therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs were defined as any AE with an onset date on or after the study drug start date.

    2. Part A and Part B: Percentage of Participants Experiencing Treatment Emergent Laboratory Abnormalities [Day 1 through 225 days]

      Treatment-emergent laboratory abnormalities were defined as values that increase at least one toxicity grade from baseline. The most severe graded abnormality from all tests was counted for each participant.

    3. Part A and Part B Pharmacokinetic (PK) Parameter: AUCinf of Lenacapavir, TAF and Its Metabolite TFV [Part A: 0 (predose),1,2,4,8,12,24 h postdose on Day 1, anytime on Days 3,4,7,8,9,10,14,29,43,57,85,113,141,169,197,225; Part B: 0 (predose),0.5,1,2,3,4,6,8,10,12,24 and 48 h postdose on Day 1, approximately Day 1 predose time on Days 4,5,6,7,8,9,10]

      AUCinf is defined as area under the concentration versus time curve from time zero to infinity.

    4. Part A and Part B PK Parameter: AUClast of Lenacapavir, TAF and Its Metabolite TFV [Part A: 0 (predose),1,2,4,8,12,24 h postdose on Day 1, anytime on Days 3,4,7,8,9,10,14,29,43,57,85,113,141,169,197,225; Part B: 0 (predose),0.5,1,2,3,4,6,8,10,12,24 and 48 h postdose on Day 1, approximately Day 1 predose time on Days 4,5,6,7,8,9,10]

      AUClast is defined as area under the concentration versus time curve from time zero to the last quantifiable concentration.

    5. Part A and Part B PK Parameter: Cmax of Lenacapavir, TAF and Its Metabolite TFV [Part A: 0 (predose),1,2,4,8,12,24 h postdose on Day 1, anytime on Days 3,4,7,8,9,10,14,29,43,57,85,113,141,169,197,225; Part B: 0 (predose),0.5,1,2,3,4,6,8,10,12,24 and 48 h postdose on Day 1, approximately Day 1 predose time on Days 4,5,6,7,8,9,10]

      Cmax is defined as the maximum observed concentration of drug.

    6. Part B PK Parameter: AUCinf of TFV-DP Metabolite of TAF [Part B: 0 (predose), 1, 2, 4, 6, 8, 12, 24 and 48 hours post dose on Day 1, approximately Day 1 predose time on Days 4, 5 (if possible), 6 (if possible), 7, 8, 9, 10]

      AUCinf is defined as area under the concentration versus time curve from time zero to infinity.

    7. Part B PK Parameter: AUClast of TFV-DP Metabolite of TAF [Part B: 0 (predose), 1, 2, 4, 6, 8, 12, 24 and 48 hours post dose on Day 1, approximately Day 1 predose time on Days 4, 5 (if possible), 6 (if possible), 7, 8, 9, 10]

      AUClast is defined as area under the concentration versus time curve from time zero to the last quantifiable concentration.

    8. Part B PK Parameter: Cmax of TFV-DP Metabolite of TAF [Part B: 0 (predose), 1, 2, 4, 6, 8, 12, 24 and 48 hours post dose on Day 1, approximately Day 1 predose time on Days 4, 5 (if possible), 6 (if possible), 7, 8, 9, 10]

      Cmax is defined as the maximum observed concentration of drug.

    2. Secondary Outcome
    Title Part A and Part B: Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs)
    Description An AE was any untoward medical occurrence in a clinical study participant administered a medicinal product, which does not necessarily have a causal relationship with the treatment. An AE could therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. TEAEs were defined as any AE with an onset date on or after the study drug start date.
