Evaluation of Safety, Tolerability, Pharmacokinetics, and Antiretroviral Activity of Ulonivirine (MK-8507) in Human Immunodeficiency Virus (HIV-1)-Infected Participants (MK-8507-003)

NCT ID: NCT02174159

Last Updated: 2023-04-10

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 18 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2014-09-15
• Study Completion Date: 2015-07-23

Brief Summary

The study will evaluate the safety, tolerability, pharmacokinetics, and antiretroviral activity of a single dose of ulonivirine in antiretroviral therapy (ART)-naive, HIV-1 infected participants. The hypothesis tested in the study is that at a safe and well-tolerated dose, ulonivirine has superior antiretroviral activity to a historical placebo control, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.

Conditions

Exclusion Criteria

• Mentally or legally institutionalized or incapacitated, has significant emotional problems, or has a history of clinically significant psychiatric disorder
