Human Immunodeficiency Virus (HIV)

Brief summary

The purpose of this study is to compare the antiretroviral activity of doravirine, tenofovir, lamivudine (MK-1439A), a single-tablet, once-daily (q.d.) fixed-dose combination (FDC) containing doravirine (MK-1439A) 100 mg + lamivudine 300 mg + tenofovir disoproxil fumarate 300 mg, with ATRIPLA™, a single-tablet FDC containing efavirenz 600 mg + emtricitabine 200 mg + tenofovir disoproxil fumarate 300 mg, in treatment-naive participants infected with human immunodeficiency virus (HIV). The primary hypothesis is that doravirine, tenofovir, lamivudine q.d. is non-inferior to ATRIPLA™ q.d. as assessed by the proportion of participants with HIV-1 ribonucleic acid (RNA) \<50 copies/mL (by the Abbott RealTime HIV-1 Assay) at Week 48. This study has a total duration of 384 weeks, including a 96-week double-blind period and an additional 288-week open-label period.

Detailed description

Participants in Australia, Colombia, Guatemala, Honduras, Israel, New Zealand, Peru, Russia, South Africa, and Thailand who are deriving benefit from doravirine, tenofovir, lamivudine are also eligible to continue receiving study drug during additional open-label extensions which will last for 2 years or until drug is available locally, whichever comes first.

Interventions

One doravirine, tenofovir, lamivudine tablet taken q.d. by mouth.

DRUGATRIPLA™

One ATRIPLA™ tablet taken q.d. by mouth

DRUGPlacebo

Placebo tablets matched to ATRIPLA® or Doravirine, Tenofovir, Lamivudine.

The percentage of participants in each arm with HIV-1 RNA levels \<40 copies/mL (including target detected and target not detected) at Week 48 was determined. Plasma HIV RNA levels were quantified with the Abbott RealTime HIV-1 Assay. Data were handled according to the US Food and Drug Administration (FDA) snapshot approach in which all missing data are considered treatment failures, regardless of the reason.

Time frame: Week 48

Population: The analysis population consists of all randomized participants who received ≥1 dose of study medication and had baseline HIV-1 RNA data available.

Percentage of Participants With HIV-1 RNA <40 Copies/mL at Week 96

The percentage of participants in each arm with HIV-1 RNA levels \<40 copies/mL (including target detected and target not detected) at Week 96 were determined. Plasma HIV-1 RNA levels were quantified with the Abbott RealTime HIV-1 Assay. The US Food and Drug Administration (FDA) snapshot approach (i.e., all missing data handled as treatment failures, regardless of the reason) were used for efficacy analyses.
