  • Outcome Measures

    Primary Outcome Measures

    1. Percentage of Participants With HIV-1 RNA <50 Copies/mL at Week 24 [Week 24]

      Blood samples were collected and plasma human immunodeficiency virus 1 (HIV-1) ribonucleic acid (RNA) were quantified using a real time polymerase chain reaction (PCR) assay with a lower limit of detection of 40 copies/mL. Missing values were counted as failure.

    2. Percentage of Participants With HIV-1 RNA <50 Copies/mL at Week 48 [Week 48]

      Blood samples were collected and plasma HIV-1 RNA were quantified using a real time PCR assay with a lower limit of detection of 40 copies/mL. Missing values were counted as failure.

    3. Number of Participants Experiencing Adverse Events (AEs) up to Week 144 [Up to 144 weeks]

      An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment.

    4. Number of Participants Discontinuing Study Drug Due to AEs up to Week 144 [Up to 144 weeks]

      An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment.

      Blood samples were collected and plasma HIV-1 RNA were quantified using a real time PCR assay with a lower limit of detection of 40 copies/mL, and missing values were counted as failure. 3TC and placebo are discontinued from the regimen from Week 24 up to Week 52.

    2. Percentage of Participants With HIV-1 RNA <50 Copies/mL up to 48 Weeks After 3TC and Placebo Are Discontinued From the Regimen [Up to 48 weeks]

      Blood samples were collected and plasma HIV-1 RNA were quantified using a real time PCR assay with a lower limit of detection of 40 copies/mL, and missing values were counted as failure. 3TC and placebo are discontinued from the regimen from Week 24 up to Week 52.

    3. Percentage of Participants With HIV-1 RNA <50 Copies/mL up to 48 Weeks After Starting Open-label Doravirine/Islatravir Regimen [Up to Week 192]

      Blood samples were collected and plasma HIV-1 RNA were quantified using a real time PCR assay with a lower limit of detection of 40 copies/mL. Missing values were counted as failure.

    4. Change From Baseline in Mature T-helper (CD4+ T)-Cell Count at Week 24 [Baseline and Week 24]

      Blood samples were collected and cluster of differentiation (CD4)+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value, and baseline values were carried forward for participants who discontinue due to lack of efficacy. Post-baseline data were collected after the first dose of study medication through 14 days after the last dose of study medication.

    5. Change From Baseline in CD4+ T-cell Count at Week 48 [Baseline and Week 48]

      Blood samples were collected and CD4+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value, and baseline values were carried forward for participants who discontinue due to lack of efficacy. Post-baseline data were collected after the first dose of study medication through 14 days after the last dose of study medication.

    6. Change From Baseline in CD4+ T-cell Count at Week 96 [Baseline and Week 96]

      Blood samples were collected and CD4+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value, and baseline values were carried forward for participants who discontinue due to lack of efficacy. Post-baseline data were collected after the first dose of study medication through 14 days after the last dose of study medication.

    7. Change From Baseline in CD4+ T-cell Count at Week 144 [Baseline and Week 144]

      Blood samples were collected and CD4+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value, and baseline values were carried forward for participants who discontinue due to lack of efficacy. Post-baseline data were collected after the first dose of study medication through 14 days after the last dose of study medication.

    8. Change From Baseline in CD4+ T-cell Count at Week 192 [Baseline and Week 192]

      Blood samples were collected and CD4+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value.

      An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment. 3TC and placebo are discontinued from the regimen from Week 24 up to Week 52.

    10. Number of Participants Discontinuing Study Drug Due to AEs Through 24 Weeks After 3TC and Placebo Are Discontinued From the Regimen [Up to 24 weeks]

    Title Change From Baseline in CD4+ T-cell Count at Week 96
    Description Blood samples were collected and CD4+ T-cell counts were performed, where baseline measurements are defined as the Day 1 value, and baseline values were carried forward for participants who discontinue due to lack of efficacy. Post-baseline data were collected after the first dose of study medication through 14 days after the last dose of study medication.

    Arm/Group Title Islatravir 0.25mg Islatravir 0.75mg Islatravir 2.25mg Doravirine, Tenofivir, Lamivudine
    Arm/Group Description Participants were treated QD with 0.25 mg islatravir, 100 mg DOR, 300 mg 3TC, and placebo to doravirine, tenofovir, lamivudine for a minimum of 24 weeks. For participants with HIV-1 RNA <50 copies/mL and no PDVF, between week 24 through week 52, 3TC and placebo to doravirine, tenofovir, lamivudine was discontinued. After a minimum 48 weeks of treatment, participants were switched to open label dose of 0.75 mg islatravir and DOR 100 mg QD and continued treatment until Week 144. At Week 144 participants received the fixed dose combination of doravirine (100mg)/islatravir (0.75mg) QD open label and continued treatment until Week 192. Participants were treated QD with 0.75 mg islatravir, 100 mg DOR, 300 mg 3TC, and placebo to doravirine, tenofovir, lamivudine for a minimum of 24 weeks. For participants with HIV-1 RNA <50 copies/mL and no PDVF, between week 24 through week 52, 3TC and placebo to doravirine, tenofovir, lamivudine was discontinued. After a minimum 48 weeks of treatment, participants were switched to open label dose of 0.75 mg islatravir and DOR 100 mg QD and continued treatment until Week 144. At Week 144 participants received the fixed dose combination of doravirine (100mg)/islatravir (0.75mg) QD open label and continued treatment until Week 192. Participants were treated QD with 2.25 mg islatravir, 100 mg DOR, 300 mg 3TC, and placebo to doravirine, tenofovir, lamivudine for a minimum of 24 weeks. For participants with HIV-1 RNA <50 copies/mL and no PDVF, between week 24 through week 52, 3TC and placebo to doravirine, tenofovir, lamivudine was discontinued. After a minimum 48 weeks of treatment, participants were switched to open label dose of 0.75 mg islatravir and DOR 100 mg QD and continued treatment until Week 144. At Week 144 participants received the fixed dose combination of doravirine (100mg)/islatravir (0.75mg) QD open label and continued treatment until Week 192. Participants were treated QD with placebo to islatravir, placebo to DOR, placebo to 3TC, and doravirine, tenofovir, lamivudine consisting of 100 mg DOR + 300 mg 3TC + 300 mg tenofovir disoproxil fumarate (TDF) for a minimum of 24 weeks. Between week 24 through week 52 placebo treatments were discontinued and participants received only doravirine, tenofovir, lamivudine QD open label up to Week 144.
