New study aims to safely prevent TB in pregnant women with HIV
NCT ID NCT05122026
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
