Study Endpoints

Primary Endpoints

Percentage of Participants With Sustained Viral Response (SVR) at Week 72
Week 72

For participants who received filibuvir, had undetectable HCV RNA from Week 4 through 24 and discontinued therapy at Week 24, SVR was defined as undetectable plasma HCV RNA levels (\<15 IU/mL) at both Week 24 (End of Treatment \[EOT\]) and Week 72, regardless of the HCV RNA levels between Week 24 and 72. For participants who received filibuvir, had detectable HCV RNA at Week 4 or later and discontinued therapy at Week 48 or who received placebo, SVR was defined as undetectable plasma HCV RNA levels (\<15 IU/mL) at both Week 48 (EOT) and Week 72, regardless of the HCV RNA levels between Week 48 and 72.

What phase is Filibuvir in?

Filibuvir is in Phase 2 clinical development. It has completed one Phase 2 trial and two Phase 1 trials, but it is not approved and remains investigational.

What clinical trials is Filibuvir in?

Filibuvir has been studied in three completed trials: NCT00918476, a Phase 1 drug interaction study; NCT00987337, a Phase 2 trial in treatment naive HCV genotype 1 subjects; and NCT01210404, a Phase 1 drug interaction study with methadone.

Is Filibuvir the same as PF-00868554?

Filibuvir is also known by the code name PF-00868554. This alternative name is used in some clinical and research contexts to refer to the same investigational drug.
