Clinical Trial Summary

This is a single-group, open-label, multi-site study in pediatric participants with human immunodeficiency virus type 1 (HIV-1) infection, aged 4 weeks to <12 years and weighing <45 kg, who are treatment-naive (TN) or have been virologically suppressed (VS) on stable combination antiretroviral therapy (cART) for ≥3 months with no history of treatment failure. The first primary objective is to evaluate the steady state pharmacokinetics (PK) of doravirine (DOR) [MK-1439] when given in combination with 2 nucleoside/nucleotide analog reverse transcriptase inhibitors (NRTIs) or as part of the fixed dose combination (FDC) of DOR/lamivudine (3TC)/tenofovir disproxil fumarate (TDF) in participants ≥6 to <12 years and weighing ≥14 to <45 kg. The second primary objective is to evaluate the safety and tolerability of DOR when given with 2 NRTIs or as part of the FDC of DOR/3TC/TDF, in participants ≥6 to 12 years and weighing ≥14 to <45 kg, through Week 24.


Clinical Trial Description

Participants who complete the Week 96 visit will be eligible to enroll in an Extension Study in which they may continue to receive DOR until it is commercially available, or for up to an additional 224 weeks (whichever comes first). ;
