MK-4250

The study will evaluate the safety, tolerability, pharmacokinetics, and anti-retroviral activity of MK-4250 monotherapy in anti-retroviral therapy (ART)-naïve, HIV-1 infected participants. The primary hypothesis of the study is that at a dose that is sufficiently safe and generally well tolerated, MK-4250 has superior antiretroviral activity compared to a historical placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) (log10 copies/mL) at 168 hours postdose.
