  Purpose
The hypothesis tested in this study is that doravirine (MK-1439) at the final dose selected is superior to efavirenz, each given in combination with TRUVADA®, as measured by the percentage of participants with CNS events by Week 8. If superiority is established at Week 8, the same hypothesis will be tested for Week 24.

Primary Outcome Measures:
  • Percentage of Participants With At Least 1 AE in Weeks 0-24: Doravirine (All Doses) vs Efavirenz (Part I) [ Time Frame: Up to Week 24 ]
    Assessment of the percentage of participants receiving doravirine at all doses (25 mg, 50 mg, 100 mg, or 200 mg), compared with participants receiving efavirenz 600 mg, who had at least 1 AE over 24 weeks of treatment. An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product.The percentage of participants in any treatment group with at least 1 AE was primarily assessed for Weeks 0-24.

  • Percentage of Participants Who Discontinued Study Therapy Due to AEs in Weeks 0-24: Doravirine (All Doses) vs Efavirenz (Part I) [ Time Frame: Up to Week 24 ]
    Assessment of the percentage of participants receiving doravirine at all doses (25 mg, 50 mg, 100 mg, or 200 mg), compared with participants receiving efavirenz 600 mg, who discontinued therapy due to an AE over 24 weeks of treatment. An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product.The percentage of participants in any treatment group who discontinued therapy due to an AE was primarily assessed for Weeks 0-24.

  • Percentage of Participants With At Least 1 AE in Weeks 0-24: Doravirine 100 mg vs Efavirenz (Part I & Part II Combined) [ Time Frame: Up to Week 24 ]
    Assessment of the percentage of participants receiving doravirine at 100 mg, compared with participants receiving efavirenz 600 mg, who had at least 1 AE over 24 weeks of treatment. An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product.The percentage of participants in any treatment group with at least 1 AE was assessed for Weeks 0-24.

  • Percentage of Participants With CNS Events by Week 8: Doravirine 100 mg vs Efavirenz (Part I & Part II Combined) [ Time Frame: Up to Week 8 ]
    Assessment of the percentage of participants receiving doravirine at 100 mg, compared with participants receiving efavirenz 600 mg, who had CNS events over 8 weeks of treatment. CNS events were pooled and evaluated as pre-specified by the protocol (depression, nightmare, confusional state, suicidal ideation, nervous system disorder, psychotic disorder, abnormal dreams, suicide attempt, acute psychosis, delirium, depressed level of consciousness, hallucination, hallucination auditory, hallucination visual, completed suicide, suicidal behavior, major depression, depressed mood, depressive symptom, insomnia, disturbance in attention, somnolence, dizziness, or concentration impaired). The percentage of participants in either treatment group with CNS events was assessed over Weeks 0-8.

    Assessment of the percentage of participants receiving doravirine at 100 mg, compared with participants receiving efavirenz 600 mg, who had CNS events over 24 weeks of treatment.

Detailed Description:

Part I - Dose-Ranging. Part I will evaluate the (1) safety and tolerability and (2) efficacy (antiretroviral activity) of 4 doses of doravirine compared with efavirenz, when each is given in combination with TRUVADA® for at least 24 weeks in approximately 200 participants. A single dose of doravirine will be selected for further study after all participants complete the Week 24 visit in Part I. Participants receiving any dose of doravirine in Part I will be switched to the selected doravirine dose and continue in the study for up to 96 weeks, but will not be randomized to Part II.

Part II - Selected Dose. Part II will be initiated after the doravirine dose has been selected as indicated above for Part 1. Approximately 120 additional participants will be randomized in 1:1 ratio to the selected dose of doravirine or efavirenz, each in combination with TRUVADA® for 96 weeks of blinded treatment. Part II will evaluate the safety of the selected dose compared with efavirenz, particularly with regard to central nervous system (CNS) adverse events.
