Summary

This study is testing two tuberculosis (TB) prevention treatments in pregnant women who also have HIV. The goal is to see if these treatments are safe and how they interact with the HIV medication dolutegravir. About 252 pregnant women will take either a daily TB drug for one month or a weekly dose for three months. The study will monitor for side effects and check drug levels in the blood.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
isoniazid and rifapentine
What this could lead to
If successful, this could provide a safe way to prevent tuberculosis in pregnant women with HIV without compromising their HIV treatment.
What could go wrong
This is an early-phase study with only 252 participants, so results may not apply to all pregnant women. There is a risk of side effects like liver problems or drug interactions.
