Primary Outcome Measures

Name	Time	Method
Main Objective: To assess the bioequivalence of SOF/VEL as a crushed (test) tablet compared to a whole (reference) tablet in patients treated with SOF/VEL.;Secondary Objective: To evaluate the safety and tolerability of crushed Epclusa tablets in patients. ;Primary end point(s): Geometric Mean Ratios and the 90% CI interval of the pharmacokinetic parameters (AUC0-tau, Cmax,ss and Ctrough) and median of t½ and tmax,ss of sofosbuvir, GS-331007 and velpatasvir of a crushed tablet (intervention) compared to a whole tablet (reference).<br><br>AUC0-24 and Cmax,ss GMR with a 90% CI falling entirely within the range of 0.8 to 1.25 are considered bioequivalent.<br><br>;Timepoint(s) of evaluation of this end point: Pharmacokinetic (PK) curves will be recorded for sofosbuvir and velpatasvir. The curve will be recorded after administration of a whole tablet and a crushed tablet.

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): To evaluate the safety and tolerability of crushed SOF/VEL tablets in patients.<br>Adverse events after administration of (crushed) SOF/VEL will be described and compared (including clinically relevant laboratory abnormalities).<br>;Timepoint(s) of evaluation of this end point: Safety assessment on every study visit. Evaluation at the end of the trial.
