What this research studies

This research focuses on understanding how the medications Glecaprevir and Pibrentasvir work in pregnant individuals with hepatitis C, including those who are also living with HIV. The study will monitor the safety of these medications for both the pregnant person and their infant, tracking health outcomes for three months after birth. Participants will be closely observed to gather data on how the drugs are processed in the body during pregnancy and postpartum. The goal is to ensure that effective treatments can be safely administered to this vulnerable population.

Who could benefit from this research

Good fit: Ideal candidates for this research include pregnant individuals diagnosed with hepatitis C, with or without HIV.

Not a fit: Patients who are not pregnant or those without hepatitis C may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to safer treatment options for pregnant individuals with hepatitis C, improving health outcomes for both mothers and their infants.

How similar studies have performed: Previous research has shown promise in treating hepatitis C in various populations, but this specific approach during pregnancy is relatively novel.
