Pregnant women with hepatitis c get new hope in drug trial
NCT ID NCT07040319
First seen Jun 25, 2026 · Last updated Aug 14, 2026 · Updated 4 times
Summary
This study is testing the safety and drug levels of glecaprevir/pibrentasvir, a hepatitis C treatment, in 30 pregnant women with or without HIV. The goal is to see how the drug works during pregnancy and to monitor the health of both mothers and their infants up to 10 weeks after birth. It is an early-phase trial, so results will help guide future treatment options.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- glecaprevir/pibrentasvir (a combination antiviral drug)
- What this could lead to
- If successful, this could provide a safe way to treat hepatitis C during pregnancy, potentially preventing mother-to-child transmission and improving outcomes for both mother and baby.
- What could go wrong
- This is an early-phase study with only 30 participants, so results may not apply to all pregnant women. There are also unknown risks to the fetus and infant, and the treatment may not work as well in those with HIV.
