Brief Summary:
To establish a new treatment option for treatment-naïve participants with HIV-1, the efficacy and safety of doravirine will be determined relative to a protease inhibitor (PI). Participants will receive double-blind treatment during the 96-week Base Study. Eligible participants in either of the Base Study groups will continue to receive the doravirine-containing regimen open label for an additional 96 weeks in the Study Extension 1. Eligible participants who are deriving benefit will continue in Study Extension 2 to receive the doravirine-containing regimen open label until doravirine becomes locally available or for an additional 96 weeks, whichever comes first. The primary hypothesis is that doravirine 100 mg once a day (q.d.) is non-inferior to darunavir/ritonavir (800 mg/100 mg) q.d., each in combination with TRUVADA™ or EPZICOM™/KIVEXA™, as assessed by the proportion of participants with HIV-1 ribonucleic acid (RNA) <50 copies/mL at Week 48. If non-inferiority is established, then the superiority of doravirine 100 mg q.d. compared to darunavir/ ritonavir (800 mg/100 mg) q.d. will be assessed.

Primary Outcome Measures :
  1. Percentage of Participants Achieving Plasma HIV-1 RNA <50 Copies/mL at Week 48 [ Time Frame: Week 48 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <50 copies/mL at Week 48 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. Percentage of Participants Achieving Plasma HIV-1 RNA <50 Copies/mL at Week 96 [ Time Frame: Week 96 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <50 copies/mL at Week 96 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.

  2. Change From Baseline in Mean CD4+ T-cell Count at Week 48 [ Time Frame: Baseline and Week 48 ]
    CD4+ T-cell counts were quantified by a central laboratory using a commercially available assay.

  3. Change From Baseline in Mean CD4+ T-cell Count at Week 96 [ Time Frame: Baseline and Week 96 ]
    CD4+ T-cell counts were quantified by a central laboratory using a commercially available assay.

  4. Mean Change From Baseline in Fasting Low Density Lipoprotein Cholesterol (LDL-C) at Week 48 [ Time Frame: Baseline and Week 48 ]
    Serum LDL-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.

  5. Mean Change From Baseline in Fasting Non-High Density Lipoprotein Cholesterol (Non-HDL-C) at Week 48 [ Time Frame: Baseline and Week 48 ]
    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 LOCF approach was applied for missing data or data collected after modifying lipid-lowering therapy.

  6. Mean Change From Baseline in Fasting High Density Lipoprotein Cholesterol (HDL-C) at Week 48 [ Time Frame: Baseline and Week 48 ]
    Serum 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 LOCF approach was applied for missing data or data collected after modifying lipid-lowering therapy.

  7. Mean Change From Baseline in Fasting Total Cholesterol at Week 48 [ Time Frame: Baseline and Week 48 ]
    Serum total cholesterol was determined after an overnight fast. Change from Baseline was analyzed using ANCOVA models with terms for Baseline lipid level and treatment group. The LOCF approach was applied for missing data or data collected after modifying lipid-lowering therapy.

  8. Mean Change From Baseline in Fasting Triglyceride at Week 48 [ Time Frame: Baseline and Week 48 ]
    Serum triglyceride was determined after an overnight fast. Change from Baseline was analyzed using ANCOVA models with terms for Baseline lipid level and treatment group. The LOCF approach was applied for missing data or data collected after modifying lipid-lowering therapy.

  9. Percentage of Participants With Any Adverse Event [ Time Frame: Up to 98 weeks ]
    An adverse event (AE) is defined as any untoward medical occurrence in a study participant and which does not necessarily have to have a causal relationship to treatment. An adverse event can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the study treatment or protocol-specified procedure, whether or not considered related to study treatment or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the study treatment is also an AE. The percentage of participants with any AE was assessed.

  10. Percentage of Participants With Any Serious Adverse Event [ Time Frame: Up to 98 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 With Any Drug-related Adverse Event [ Time Frame: Up to 98 weeks ]
    The investigator was to determine if an AE had a reasonable possibility of a relationship to the study drug. The percentage of participants with any drug-related AE was assessed.

  12. Percentage of Participants With Any Drug-related Serious Adverse Event [ Time Frame: Up to 98 weeks ]
    The percentage of participants with any drug-related SAE was assessed.

  13. Percentage of Participants Who Discontinued Study Treatment Due to an Adverse Event [ Time Frame: Up to 96 weeks ]
    The percentage of participants who discontinued study treatment due to an AE was assessed.

  14. Percentage of Participants Achieving Plasma HIV-1 RNA <40 Copies/mL at Week 48 [ Time Frame: Week 48 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <40 copies/mL at Week 48 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.

  15. Percentage of Participants Achieving Plasma HIV-1 RNA <40 Copies/mL at Week 96 [ Time Frame: Week 96 ]
    The percentage of participants in each arm achieving HIV-1 RNA levels <40 copies/mL at Week 96 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.
