研究概览
简要总结
This study will evaluate the safety, tolerability, pharmacokinetics, and anti-retroviral therapy (ART) activity of islatravir (MK-8591) monotherapy in ART-naive, human immunodeficiency virus-1 (HIV-1) infected participants. The primary hypothesis is that at a safe and tolerable dose of islatravir, the true mean difference in the plasma HIV-1 ribonucleic acid (RNA) reduction from baseline between islatravir and placebo is at least 0.5 log (base10) copies/mL.

结局指标
主要结局
Change From Baseline in Plasma HIV-1 RNA at 168 Hours Post-Dose
时间窗: Baseline and 168 hours (7 days) post-dose
Plasma HIV-1 RNA was measured using the Roche COBAS Ampliprep/COBAS TaqMan HIV-1 test v.2.0, which has a linear range from 20 to 10,000,000 copies/mL. The lower limit of detection has 100% specificity at 20 copies/mL. Additionally, the test increases the probability of detection and expands coverage by targeting two highly conserved regions of the HIV-1 genome to compensate for the possibility of mutations or mismatches.
Number of Participants With One or More Adverse Events
时间窗: Up to 21 days post-dose
An adverse event (AE) is any untoward medical occurrence in a study participant administered a pharmaceutical product that does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product.
