Study to Investigate the Safety and Efficacy of Sofosbuvir/Velpatasvir in Adolescents and Children With Chronic HCV Infection
Purpose
This study will have 2 parts: Pharmacokinetics (PK) Lead-in Phase and the Treatment Phase. The primary objective of the PK Lead-in Phase is to evaluate the steady state PK and confirm the dose of sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) in pediatric participants with chronic hepatitis C virus (HCV) infection. The primary objective of the Treatment Phase is to evaluate the safety and tolerability of SOF/VEL for 12 weeks in pediatric participants with chronic HCV.

Experimental 12 to < 18 Years Old |
PK Lead-in Phase: Sofosbuvir/Velpatasvir (SOF/VEL) 400/100 mg once daily for 7 days. Participants who complete the PK lead-in phase, continue into the treatment phase with no interruption of study drug administration and additional participants will be enrolled into the treatment phase once the appropriateness of the dose is confirmed by PK results from the PK lead-in phase. Treatment Phase: SOF/VEL 400/100 mg once daily for 12 weeks. |

Experimental 6 to < 12 Years Old |
PK Lead-in Phase: SOF/VEL 200/50 mg once daily for 7 days. Participants who complete the PK lead-in phase, continue into the treatment phase with no interruption of study drug administration and additional participants will be enrolled into the treatment phase once the appropriateness of the dose is confirmed by PK results from the PK lead-in phase. Treatment Phase: SOF/VEL 200/50 mg once daily for 12 weeks. |

Experimental 3 to < 6 Years Old |
PK Lead-in Phase: SOF/VEL 200/50 mg once daily for 7 days for participants who weigh ≥ 17 kg. SOF/VEL 150/37.5 mg once daily for 7 days for participants who weigh < 17 kg. Participants who complete the PK lead-in phase, continue into the treatment phase with no interruption of study drug administration and additional participants will be enrolled into the treatment phase once the appropriateness of the dose is confirmed by PK results from the PK lead-in phase. Treatment Phase: SOF/VEL 200/50 mg once daily for 12 weeks for participants who weigh ≥ 17 kg. SOF/VEL 150/37.5 mg once daily for 12 weeks for participants who weigh < 17 kg. |
