A Study of MK-8527 in Human Immunodeficiency Type 1 Virus (HIV-1) Infected Participants (MK-8527-002)

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 study will evaluate the anti-retroviral activity of MK-8527 in HIV-1 infected, ART-naïve participants. The primary hypothesis is that MK-8527 has superior anti-retroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.

Up to five panels (Panels A-E) of 6 participants each will be enrolled in a sequential manner. In each panel, participants will receive a single dose of MK-8527 up to 50 mg. Historical data from previous single does studies will be used for placebo (control) comparisons.

Inclusion Criteria

• Is documented HIV-1 positive
• Diagnosed with HIV-1 infection ≥ 3 months prior to screening or perform the French 2008 Haute Autorité de Santé (HAS) Algorithm to confirm chronic HIV.

• If the male participant has a female partner(s) of childbearing potential, he must agree to use a medically acceptable method of contraception during the study and for 120 days after the last dose of study drug. If their partner is pregnant, males must agree to use a condom and no additional method of contraception is required for the pregnant partner
• If the participant is a female with reproductive potential, she must demonstrate a serum β-human chorionic gonadotropin (β-hCG) level consistent with the nongravid state at the prestudy (screening) visit and agree to use (and/or have their partner use) 2 acceptable methods of birth control beginning at the prestudy (screening) visit, throughout the study (including washout intervals between treatment periods/panels) and until 28 days after the last dose of study drug.
• If the participant is a postmenopausal female: she is without menses for at least 1 year and have a documented follicle stimulating hormone (FSH) level in the postmenopausal range at prestudy (screening)
• If the participant is a surgically sterile female: she is status posthysterectomy, or oophorectomy

Exclusion Criteria

Participants with a remote history of uncomplicated medical events (eg, uncomplicated kidney stones, as defined as spontaneous passage and no recurrence in the last 5 years, or childhood asthma) may be enrolled in the study at the discretion of the investigator.
• Is mentally or legally incapacitated at the time of the prestudy (screening) visit or expected during the conduct of the study or has a history of clinically significant psychiatric disorder over the last 5 years. Participants who have had situational depression may be enrolled in the study at the discretion of the investigator.
