History of Changes
This clinical study will evaluate whether grazoprevir and elbasvir is efficacious, safe, and well-tolerated in peginterferon alfa plus ribavirin experienced patients who inject drugs (PWID) and men who sex with men (MSM) with genotype 1 HCV and HIV co-infection.

Primary Outcome Measures
Sustained virological response
[ Time Frame: 12 weeks after the end of therapy ]
The proportion of sustained virological response 12 weeks after the end of therapy after the treatment of grazoprevir and elbasvir
- Severe adverse effects
[ Time Frame: during the treatment of grazoprevir and elbasvir ]
The frequency of severe adverse effects leading to discontinuation
|Study Start Date:||October 20, 2017|

|Primary Completion Date:||November 30, 2018 (Final data collection date for primary outcome measure)|
Genotype 1 HCV and HIV co-infection
Patients with chronic Genotype 1 HCV and HIV co-infection, with or without resistance-associated substitution (RAS) of NS5A, received grazoprevir and elbasvir in a fixed-dose combination tablet once daily with ribavirin for 16 weeks, and patients with chronic genotype 1b received grazoprevir and elbasvir once daily for 12 weeks.
grazoprevir and elbasvir
For patients with chronic genotype 1a, with or without resistance associated variant (RAV) of NS5A, are expected to receive grazoprevir and elbasvir in a fixed-dose combination tablet once daily with ribavirin for 16 weeks, and for patients with chronic genotype 1b are expected to receive grazoprevir and elbasvir in a fixed-dose combination tablet once daily for 12 weeks.
Primary Objective •To assess the efficacy of grazoprevir 100mg and elbasvir 50mg by
determining the proportion of sustained virological response 12 weeks after the end of
therapy (SVR12; HCV RNA concentration less than 10 IU/ mL at follow-up week 12) in
peginterferon alfa plus ribavirin experienced patients with genotype 1 HCV and HIV
co-infection, compared with treatment-naïve patients with 1 HCV and HIV co-infection.
•To assess the tolerability of grazoprevir 100mg and elbasvir 50mg in peginterferon alfa plus ribavirin experienced patients by measuring frequency of SAEs and AEs leading to discontinuation.
|Ages Eligible for Study:||20 Years to 80 Years|

- ARV with protease inhibitor containing regimen HBsAg and HBV core antibody should be
