Primary Outcome Measures:
  • Change from baseline in HIV-RNA viral load [ Time Frame: Baseline and Day 7 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Observed Concentration at 24 hours post-dose (C24 hr) following administration of doravirine [ Time Frame: 24 hours after dosing on Days 1-7 ] [ Designated as safety issue: No ]
  • Area under the concentration curve from Hour 0 to Hour 24 (AUC0-24hr) following administration of doravirine [ Time Frame: From Hour 0 to Hour 24 after dosing on Days 1-7 ] [ Designated as safety issue: No ]
  • Maximum Observed Concentration (Cmax) following administration of doravirine [ Time Frame: Days 1-7 ] [ Designated as safety issue: No ]
  • Time to Maximum Observed Concentration (Tmax) following administration of doravirine [ Time Frame: Days 1-7 ] [ Designated as safety issue: No ]

Enrollment: 18
Study Start Date: October 2011
Study Completion Date: April 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Panel A doravirine Drug: Doravirine
Doravirine tablets, orally, once daily for 7 days at a dose of 25 mg in Panel A and 200 mg in Panel B; dose in Panel C to be determined (≤200 mg).
Experimental: Panel B doravirine
Panel B will initiate upon satisfactory review of safety and tolerability from Panel A, and all safety, tolerability and pharmacokinetic data from the study MK-1439-001.
Drug: Doravirine
Doravirine tablets, orally, once daily for 7 days at a dose of 25 mg in Panel A and 200 mg in Panel B; dose in Panel C to be determined (≤200 mg).
Experimental: Panel C doravirine
Panel C is optional. If conducted, the dose will be confirmed after review of data from prior panels.
Drug: Doravirine
Doravirine tablets, orally, once daily for 7 days at a dose of 25 mg in Panel A and 200 mg in Panel B; dose in Panel C to be determined (≤200 mg).
Experimental: Panel A, B, C Placebo
Participants on each Panel will be randomized to receive placebo.
Drug: Placebo
Placebo tablets once daily for 7 days.
