Official title

A Phase 2 Clinical Study to Evaluate the Pharmacokinetics, Safety, and Efficacy of Doravirine/Islatravir in Pediatric Participants With HIV-1 Infection Who Are Virologically Suppressed or Treatment-Naïve, Are Less Than 18 Years of Age, and Weigh Greater Than or Equal to 35 kg

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a phase 2, single-group, multi-site, open-label study of an islatravir/doravirine (ISL/DOR, MK-8591A) fixed dose combination (FDC) for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in pediatric participants who are virologically suppressed (VS) on antiretroviral therapy (ART) for ≥3 months or are treatment-naive (TN). The primary purposes of the study are 1) to examine the steady-state pharmacokinetics (PK) of ISL in plasma; 2) the steady-state PK of ISL-triphosphate (ISL-TP) in peripheral blood mononuclear cells (PBMCs); and 3) to examine the safety and tolerability of ISL/DOR.
