Brief Summary:
The multicenter, open label, randomized study will evaluate the safety and efficacy of a switch to MK-1439A (MK-1439 [doravirine] plus lamivudine and tenofovir disoproxil fumarate) in HIV-1-infected participants virologically suppressed on a protocol-specified antiretroviral regimen. The primary hypothesis is that a switch to MK-1439A will be non-inferior to continuation of the regimen at Screening for 24 weeks, as assessed by the proportion of participants maintaining HIV-1 ribonucleic acid (RNA) <50 copies/mL. The Base Study results will be based on the first 48 weeks of this ongoing study.

Condition or disease Intervention/treatment Phase
HIV-1 Infection Drug: MK-1439A Drug: Baseline regimen of ritonavir- or cobicistat-boosted protease inhibitor Drug: Baseline regimen of cobicistat-boosted elvitegravir Drug: Baseline regimen of a non-nucleoside reverse transcriptase inhibitor Drug: Baseline regimen of two nucleoside reverse transcriptase inhibitors Phase 3

Detailed Description:
Two optional study extensions are planned. Study Extension 1 will evaluate safety of the switch to MK-1439A for an additional 2 years beyond the Base Study. Study Extension 2 will evaluate safety of the switch to MK-1439A until MK-1439A becomes locally available, or 2 years beyond Study Extension 1, whichever comes first.

Primary Outcome Measures :
  1. Percentage of Participants Maintaining Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) <50 Copies/mL [ Time Frame: Immediate Switch to MK-1439A arm: Week 48; Delayed Switch to MK-1439A arm: Week 24 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <50 copies/mL was determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach and all missing data were considered treatment failures, regardless of the reason.


Secondary Outcome Measures :
  1. Mean Change From Baseline in Fasting Low-density Lipoprotein Cholesterol (LDL-C) [ Time Frame: Baseline and Week 24 ]
    To evaluate the effect on fasting LDL-C of an immediate switch to DOR/3TC/TDF on Study Day 1 compared with continuation of a ritonavir-boosted, PI-based regimen, as measured by mean change from baseline in each treatment group. The Last Observation Carry Forward (LOCF) approach was applied to missing data and data collected after a participant initiated lipid-modifying therapy.

  2. Mean Change From Baseline in Fasting Non-high-density Lipoprotein Cholesterol (Non-HDL-C) [ Time Frame: Baseline and Week 24 ]
    Serum non-HDL-C was determined after an overnight fast. Change from Baseline was analyzed using ANCOVA models with terms for Baseline lipid level and treatment group. The Last Observation Carry Forward (LOCF) approach was applied for missing data or data collected after modifying lipid lowering therapy.

  3. Percentage of Participants Maintaining HIV-1 RNA <50 Copies/mL [ Time Frame: Week 24 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <50 copies/mL was determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach and all missing data were considered treatment failures, regardless of the reason.

  4. Mean Change From Baseline in Cluster of Differentiation (CD4) Cell Counts [ Time Frame: Immediate Switch to MK-1439A arm: Baseline and Week 48; Delayed Switch to MK-1439A arm: Baseline and Week 24 ]
    The mean change from baseline in CD4 cell counts was assessed using the Observed Failure (OF) approach. With the OF approach, baseline values were carried forward for participants who discontinued due to lack of efficacy. Cell counts were measured and expressed as cells/mm^3, and percent change was then calculated. CD4 cell counts were quantified by a central laboratory using a commercially available assay.

  5. Mean Change From Baseline in Cluster of Differentiation (CD4) Cell Counts [ Time Frame: Baseline and Week 24 ]
    The mean change from baseline in CD4 cell counts at Week 48 was assessed using the Observed Failure (OF) approach. With the OF approach, baseline values were carried forward for participants who discontinued due to lack of efficacy. Cell counts were measured and expressed as cells/mm^3, and percent change was then calculated. CD4 cell counts were quantified by a central laboratory using a commercially available assay.

  6. Percentage of Participants Maintaining HIV-1 RNA <40 Copies/mL [ Time Frame: Immediate Switch to MK-1439A arm: Week 48; Delayed Switch to MK-1439A arm: Week 24 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <40 copies/mL was determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach and all missing data were considered treatment failures, regardless of the reason.

  7. Percentage of Participants Maintaining HIV-1 RNA <40 Copies/mL [ Time Frame: Immediate Switch to MK-1439A arm: Week 24; Delayed Switch to MK-1439A arm: Week 24 ]
    To evaluate the immunological effect of an immediate switch to MK -1439A on Study Day 1 compared with continuation of a ritonavir boosted, PI-based regimen, as measured by the proportion of subjects maintaining HIV-1 RNA below the limit of quantification (BLoQ) by the Abbott RealTime HIV-1 Assay (<40 copies/mL) in both treatment groups.

  8. Percentage of Participants With HIV-1 RNA >=50 Copies/mL [ Time Frame: Immediate Switch to MK-1439A arm: Week 48; Delayed Switch to MK-1439A arm: Week 24 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels >=50 copies/mL was determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) "snapshot" approach.

  9. Percentage of Participants Experiencing ≥1 Adverse Event (AE) [ Time Frame: Up to week 24 ]
    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

  10. Percentage of Participants Experiencing ≥1 Serious Adverse Event (SAE) [ Time Frame: Up to 24 weeks ]
    A serious adverse event is an AE that results in death, is life threatening, results in persistent or significant disability or incapacity, results in or prolongs a hospitalization, is a congenital anomaly or birth defect, is a cancer, is associated with an overdose, or is another important medical event. The percentage of participants with any SAE was assessed.

  11. Percentage of Participants Discontinuing From Study Medication Due to an AE(s) [ Time Frame: Up to Week 24 ]
    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
