MK-8527 Single-Dose Trial in HIV-1 Infected Participants (MK-8527-004)

A Single-Dose Clinical Trial to Study the Safety, Tolerability, Pharmacokinetics, and Anti-Retroviral Activity of MK-8527 Monotherapy in Anti-Retroviral Therapy (ART)-Naïve, HIV-1 Infected Participants

This is a single-dose clinical study to evaluate the safety, tolerability, pharmacokinetics, and anti-retroviral activity of MK-8527 in antiretroviral therapy (ART)-naïve participants living with human immunodeficiency virus type 1 (HIV-1) infection. The primary hypothesis is that, at a dose that is safe and generally well tolerated, MK-8527 will have antiretroviral activity as measured by a reduction from baseline in plasma HIV-1 ribonucleic acid (RNA) of ≥1.0 log10 copies/mL. A total of 4 arms was initially planned but Arm D was never initiated as the primary objectives were achieved following completion of Arms A to C.

Inclusion Criteria:

• Is in good health other than HIV-1 infection
• Is documented HIV-1 positive
• Is ART-naïve, which is defined as not having received any marketed antiretroviral agent for treatment of HIV-1 infection (prior use of an ART for PrEP or investigational therapy is permitted if the last dose was ≥30 days prior to study drug administration)
• Is willing to receive no other ART for the monitoring period of this study

Exclusion Criteria:

• Has a history of clinically significant endocrine, GI, cardiovascular, hematological, hepatic, immunological (outside of HIV-1 infection), renal, respiratory, genitourinary, or major neurological (including stroke and chronic seizures) abnormalities or diseases
• Is unable to refrain from or anticipates the use of any medication, including prescription and nonprescription drugs or herbal remedies beginning approximately 2 weeks (or 5 half-lives) prior to administration of the initial dose of study intervention, throughout the study, until the poststudy visit
• Has participated in another investigational study within 4 weeks (or 5 half-lives, whichever is greater) prior to the prestudy (screening) visit
