AUClast is defined as the area under the plasma concentration versus time curve from time zero to the last quantifiable concentration.
AUCinf is defined as the area under the plasma concentration versus time curve extrapolated to infinite time.
Cmax is defined as the maximum observed plasma concentration of drug.
The primary outcome measure is the pharmacokinetic parameters of GS-5816 which will include AUClast, AUCinf, and Cmax.
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).
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.
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.

Velpatasvir is an investigational small molecule being developed for the treatment of chronic Hepatitis C Virus (HCV) infection. It is studied in patients with chronic HCV, and clinical trials have evaluated its safety, tolerability, pharmacokinetics, and antiviral activity in this population.
Velpatasvir is a small molecule antiviral agent. While its specific molecular target is not disclosed in the available information, it is being studied for its antiviral activity against Hepatitis C Virus. The drug is in clinical development for chronic HCV infection.
Velpatasvir is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol GILD. Gilead is conducting clinical trials to evaluate the drug's safety and efficacy in patients with chronic Hepatitis C Virus infection.
Velpatasvir is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Clinical trials are ongoing or completed to assess its safety, tolerability, and pharmacokinetics in participants with chronic HCV infection.
Velpatasvir has been studied in two completed Phase 1 trials. NCT01740791 evaluated safety, tolerability, pharmacokinetics, and antiviral activity in 103 participants with chronic HCV. NCT02002767 assessed pharmacokinetics in 19 participants with normal renal function and severe renal impairment, including healthy volunteers.
Velpatasvir is a distinct investigational compound developed by Gilead Sciences. It is not identified as being the same as any other named drug in the available information. Its development focuses on treating chronic Hepatitis C Virus infection, and it is being studied in early-phase clinical trials.
