Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
\- Present treatment for hepatitis C includes the use of a weekly injection and two different pills. This treatment is associated with serious side effects. Drugs that can be taken by mouth and cure HCV infection without serious side effects would be a great help to the large number of people infected with HCV. GS-7977 and GS-5885 are new medications being developed to treat the hepatitis C virus (HCV) infection. They are still being researched and are not approved by the Food and Drug Administration. They are being developed as treatment for hepatitis C as a single pill taken once a day.
Objectives:
\- To determine whether a combination of the two study drugs can safely and effectively treat HCV infection in people with HIV infection and who do not have cirrhosis of the liver.
Eligibility:
\- Individuals who have HIV infection and have liver disease caused by infection with HCV.
Design:
* Participants will be screened with a physical exam and medical history. Blood samples will be collected. Urine samples will be collected from participants who might become pregnant. If a participant has not had a liver biopsy in the past 3 years, one will be required.
* Participants will take one pill daily for 12 weeks. This pill will be a combination of the two study drugs.
* Treatment will be monitored with frequent clinic visits and blood tests over a total of 60 weeks.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Recently several trials have confirmed the efficacy of potent DAA therapy without concomitant IFN in the treatment of HCV monoinfected individuals. Given the improved response rates achieved with a combination of DAAs with fast HCV suppression and improved side-effect profiles; and the need for better therapy for HIV/HCV co-infected subjects, we propose a study to determine the safety, tolerability and efficacy of 12 weeks of treatment with a fixed dose combination of GS-7977 and GS-5885 in HIV/HCV Genotype 1 (GT-1) subjects. We hypothesize that anti-HCV therapy that does not rely on the host immune system will provide an enhanced rate of SVR among HIV/HCV GT-1 coinfected subjects. The findings from this study will aid in our understanding of determinants of response to an IFN-free regimen in HIV/HCV coinfected individuals.
