Summary

Background:

Human immunodeficiency virus (HIV) is treated with antiretroviral drugs. Many people with HIV also have the lung infection tuberculosis (TB). Most TB treatments are complicated. A simpler treatment of two TB drugs can be taken once a week. Researchers want to study how the HIV and TB drugs affect each other so people who take both can be treated safely.

Objective:

To study if rifapentine and isoniazid affect blood levels of the common antiretroviral TAF.

Eligibility:

Healthy adults ages 18-65 without HIV, TB, or hepatitis

Design:

Participants will fast before the screening visit. They will have a medical history, physical exam, and blood tests. Women may have a pregnancy test.

During the study, participants must:

Use effective birth control

Not take most medicine

Not drink alcohol

At the baseline visit, participants will repeat screening tests and get TAF tablets.

Participants will take TAF once a day for 31 days. They will keep track of doses and side effects.

Over 32 days, participants will have 4 long visits and 4 short.

At all visits, participants will:

Fast the night before

Get food

Take that day's TAF

Review their TAF supply

Have pregnancy and blood tests

Report side effects

At 3 visits, participants will also take the 2 TB drugs and vitamin B6.

At 3 long visits, participants will also have blood collected 8 times over 8 hours by plastic tube in an arm vein.

Around Day 46, participants will fast and have blood and pregnancy tests. Two weeks later, they will get a call to see how they are feeling.
