A Clinical Trial of MK-8527 and Rifampin in Adult Participants With Latent Tuberculosis Infection (MK-8527-019)

An Open-label, Phase 1 Study to Characterize the Effects of Rifampin on the Pharmacokinetics of MK-8527 in Adult Participants With Latent Tuberculosis Infection

Researchers are studying MK-8527, a new medicine for preventing HIV-1 (human immunodeficiency virus type 1) infection and want to learn if MK-8527 can be given together with rifampin. Rifampin is commonly used to treat people with latent tuberculosis infection (LTBI).

The main goal of this study is to learn what happens to MK-8527 in the body over time when given with and without the medication rifampin in participants with LTBI.
