Study of MK-1972 in Human Immunodeficiency Virus (HIV)-1 Infected Participants Who Have Not Previously Received Antiretroviral Therapy (MK-1972-003)
A Multiple Dose Clinical Trial to Study the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-1972 in HIV-1 Infected Patients

This is a two part study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of MK-1972 in participants with HIV-1 infections. In Part 1, participants will be randomized to receive MK-1972 (at one of 5 different dose levels given once or twice per day) or placebo. Part II will begin after the results of Part I are known; participants will be randomized to receive MK-1972 (only one dose level, twice per day) or placebo.
