Study of Doravirine/Islatravir (DOR/ISL 100 mg/0.75 mg) to Evaluate the Antiretroviral Activity, Safety, and Tolerability in Treatment-Naïve Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Infection (MK-8591A-020)

Phase 3
Completed
Conditions
HIV-1 Infection
Interventions
Drug: DOR/ISL
Drug: Placebo to BIC/FTC/TAF
Drug: Placebo to DOR/ISL
Registration Number
NCT04233879
Lead Sponsor
Merck Sharp & Dohme LLC
Brief Summary

This is a phase 3, randomized, controlled, double-blind, multisite clinical study of a once-daily fixed dose combination (FDC) of 100 mg doravirine/0.75 mg islatravir (DOR/ISL \[also known as MK-8591A\]) in treatment-naïve participants with human immunodeficiency virus type-1 (HIV-1) infection. The primary objectives are to evaluate the antiretroviral activity, safety, and tolerability of DOR/ISL compared to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF). The primary hypothesis is that DOR/ISL is noninferior or superior to BIC/FTC/TAF treatment based on the percentage of participants with HIV-1 ribonucleic acid (RNA) \<50 copies/mL at Week 48.

Detailed Description

Double-blind treatment with the assigned intervention occurs from Day 1 to Week 96, followed by an open-label portion up to Week 144. Participants who benefit from treatment in the opinion of the Investigator may continue their assigned intervention up to Week 168 (or until they have the option to enroll in a DOR/ISL 100 mg/0.25 mg study, whichever is sooner).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Human Immunodeficiency Virus (HIV)-1 Ribonucleic Acid (RNA) <50 Copies/mL at Week 48Week 48

HIV-1 RNA levels in blood samples taken at each visit were measured by the Abbott Real Time polymerase chain reaction (PCR) assay with a reliable lower limit of quantification of 40 copies/mL. The percentage of participants with HIV-1 RNA \<50 copies/mL at Week 48 was presented using the FDA Snapshot missing data approach.

Percentage of Participants Who Experienced an Adverse Event (AE) up to Week 48Up to approximately 48 weeks

An AE is any untoward medical occurrence in a study participant administered a study drug, which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug whether or not it is considered related to the study drug. The percentage of participants who experience an AE was reported.

Percentage of Participants Who Discontinued Study Treatment Due to an AE up to Week 48Up to approximately 48 weeks

An AE is any untoward medical occurrence in a study participant administered a study drug, which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the study drug whether or not it is considered related to the study drug. The percentage of participants who discontinued study treatment due to an AE were reported.
