Study Endpoints

Primary Endpoints

Pharmacokinetic (PK) Parameter of Velpatasvir: AUClast
Pre-dose (≤ 5 min), 0.5, 1, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 18, 24, 48, 72, 96, and 120 hours post-dose on Day 1

AUClast is defined as the area under the plasma concentration versus time curve from time zero to the last quantifiable concentration.

PK Parameter of Velpatasvir: AUCinf
Pre-dose (≤ 5 min), 0.5, 1, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 18, 24, 48, 72, 96, and 120 hours post-dose on Day 1

AUCinf is defined as the area under the plasma concentration versus time curve extrapolated to infinite time.

PK Parameter of Velpatasvir: Cmax
Pre-dose (≤ 5 min), 0.5, 1, 2, 2.5, 3, 3.5, 4, 6, 8, 12, 18, 24, 48, 72, 96, and 120 hours post-dose on Day 1

Cmax is defined as the maximum observed plasma concentration of drug.

Pharmacokinetic parameters of GS-5816
Up to one year

The primary outcome measure is the pharmacokinetic parameters of GS-5816 which will include AUClast, AUCinf, and Cmax.

Percentage of Participants Experiencing Treatment Emergent Adverse Events
First dose date up to Day 17 + 2 (Day 19 if Day 17 visit missing)

Treatment-emergent adverse events were defined as any new or worsening adverse event that began on or after the date of the first dose of study drug until the Day 17 study visit date + 2 (Day 19 if Day 17 visit missing).

Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities
First dose date up to Day 17 + 2 (Day 19 if Day 17 visit missing)

A treatment-emergent laboratory abnormality was defined as an increase of at least 1 abnormality grade from baseline at any postbaseline visit up to the Day 17 visit date + 2 days (or Day 19 if Day 17 visit was missing). The criteria used to grade laboratory results were as follows: Grade 1 (mild), Grade 2 (moderate), or Grade 3 (severe). Graded laboratory abnormalities were defined using the grading scheme defined in protocol (Gilead Sciences, Inc. Grading Scale for Severity of Adverse Events and Laboratory Abnormalities) for analysis purpose.

Antiviral Activity of Velpatasvir as Measured by Change in Plasma HCV RNA From Baseline
Baseline; Days 4, 5, 6, 7, 8, 10, and 17

Participants who were genotyped incorrectly but received appropriate treatment for that genotype were included in that treatment group for the efficacy analysis. Data were summarized by treatment and placebo.

Secondary Endpoints

Percentage of Participants Experiencing Treatment-Emergent Adverse Events

Percentage of Participants Experiencing Treatment-Emergent Laboratory Abnormalities
First dose date plus 30 days
