Oral Antivirals (GS-5885, Tegobuvir, and/or GS-9451) With Peginterferon Alfa 2a and Ribavirin in Treatment Experienced Subjects With Chronic Genotype 1 Hepatitis C Virus Infection

Hepatitis C, Chronic Clinical Trial

Official title:
A Phase 2b, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating Response Guided Therapy Using Combinations of Oral Antivirals (GS-5885, Tegobuvir, and/or GS-9451) With Peginterferon Alfa 2a and Ribavirin in Treatment Experienced Subjects With Chronic Genotype 1 Hepatitis C Virus Infection (Protocol GS US 256 0124)

Clinical Trial Summary

This is a Phase 2b, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating Response Guided Therapy using Combinations of Oral Antivirals (GS-5885, tegobuvir, and/or GS-9451) with Peginterferon Alfa 2a and Ribavirin in Treatment Experienced Subjects with Chronic Genotype 1 Hepatitis C Virus (HCV) Infection.

Clinical Trial Description

In September 2011, the FDA requested that Gilead make several major changes to this study because of side effects experienced by two patients in other Gilead studies.

In 2 HCV-infected people that were given tegobuvir with another experimental medication plus interferon and ribavirin, big reductions in the number of white blood cells, red blood cells and platelets were seen. Because these cases might have been related to tegobuvir when given with interferon, ribavirin and another direct antiviral agent, tegobuvir is no longer being given to people with these other medications in this study.

As a result, the study is now open label which means both you and your study doctor will know the medication you will be receiving and Arms 1 and 3 have been discontinued from the study.

All subjects enrolled in the study as of September 2nd 2011 will receive Response Guided Therapy (RGT) with both GS-5885 and GS-9451 plus PEG and RBV. ;
