Through 24 weeks post-treatment

To evaluate the antiviral efficacy as measured by sustained virologic response (SVR, defined as plasma HCV RNA \< Lower Limit of Quantification (LLoQ) at 24 weeks post-treatment) of response guided therapy (RGT) with GS-5885 + GS-9451 + PEG/RBV, or GS-5885 + PEG/RBV.

Sustained Virologic Response (SVR)
through 24 weeks of off-treatment follow-up

To evaluate antiviral efficacy as measured by sustained virologic response (SVR, defined as HCV RNA \< Lower Limit of Quantification (LLoQ) 24 weeks post-treatment) of response guided therapy (RGT) with GS-9451 + GS-5885, with peginterferon alfa-2a (PEG) and ribavirin (RBV) in treatment-experienced subjects.

Frequently asked questions about GS-5885

What is GS-5885 used for?

GS-5885 is an investigational small molecule antiviral being studied for the treatment of chronic hepatitis C virus infection, specifically chronic genotype 1a or 1b HCV. It has been evaluated in Phase 2 clinical trials, both alone and in combination with other direct-acting antivirals such as GS-9451 and tegobuvir, plus peginterferon alfa 2a and ribavirin.

Who is developing GS-5885?

GS-5885 is being developed by Gilead Sciences, Inc., which trades on the Nasdaq under the ticker GILD. Gilead sponsored all four of the Phase 2 trials of GS-5885 listed in clinical registries, which together enrolled 825 participants across the United States, Canada, Puerto Rico, Germany, and Australia.

What phase is GS-5885 in?

GS-5885 is in Phase 2 clinical development. All four registered trials of GS-5885 were Phase 2 studies, and all four are now completed, with no active trials currently listed. The studies were randomized, double-blind, and active-controlled, and enrolled a total of 825 participants with chronic genotype 1a or 1b hepatitis C.

What clinical trials is GS-5885 in?

GS-5885 has been studied in four completed Phase 2 trials: NCT01435226, NCT01434498, NCT01371578, and NCT01356160. These trials evaluated GS-5885 with GS-9451, tegobuvir, ribavirin, and peginterferon alfa 2a in treatment-experienced, interferon-ineligible or intolerant, and treatment-naive adults with chronic genotype 1 HCV infection.

Is GS-5885 the same as GS-5885 tablet?

Yes, GS-5885 tablet is another name used for GS-5885. Both names refer to the same investigational small molecule antiviral developed by Gilead Sciences for chronic hepatitis C virus infection, so searches using either name point to the same drug candidate and the same set of Phase 2 clinical trials.

How many people were enrolled in GS-5885 trials?

The four completed Phase 2 trials of GS-5885 enrolled a combined total of 825 participants. Enrollment ranged from 163 participants in NCT01434498 and NCT01371578 to 170 in NCT01435226 and 351 in NCT01356160. All trials enrolled adults aged 18 years and older with chronic genotype 1 hepatitis C virus infection.
