About this trial

This is a Phase I/II, multi-site, open-label, single arm study to describe the pharmacokinetics (PK) and safety of glecaprevir/pibrentasvir (GLE/PIB) initiated during pregnancy in women with hepatitis C virus (HCV) infection (acute or chronic) with or without HIV and to evaluate safety for their infants through 10 weeks postpartum.

Eligibility criteria

This trial does not accept healthy volunteers

At entry, 16-45 years of age (inclusive)

At entry, gestational age of 14-32 weeks, defined as greater than 13 weeks plus six days and less than or equal to 32 completed weeks gestation, as determined by the site investigator based on best obstetric estimate

Disqualifiers
