Study Endpoints
Primary Endpoints
Maximum Concentration of Velpatasvir in Maternal Plasma
Up to 9 weeks from initiation of treatment

Maximum concentration of Velpatasvir measured in maternal plasma samples. Plasma samples were obtained pre-dose and at 0.5-, 1-, 2-, 3-, 4-, 5-, 8-, and 12- and 24 hours post-dose at the 3- and 9-week visits after treatment initiation. At the 6-week visit, a single convenience blood sample was collected.
