简要总结
The purpose of this study is to evaluate the efficacy of 6 or 8 weeks of treatment regimen containing simeprevir (SMV), daclatasvir (DCV) and sofosbuvir (SOF) in treatment-naive (not having received treatment with any approved or investigational drug) participants with chronic hepatitis (inflammation of the liver) C virus (HCV) genotype 1 infection with early stages of liver fibrosis or with cirrhosis.
详细描述
This is an open-label (participants and researchers are aware about the treatment participants are receiving), and multicenter (when more than 1 hospital or medical school team work on a medical research) study. The study will consist of a Screening Phase (6 weeks); an Open-label Treatment Phase (6 weeks for Arm A and 8 weeks for Arm B); and a Post-treatment Follow-up Phase (until 24 weeks after end of study treatment). Using a staggered approach, all eligible participants will be assigned to 1 of the 2 arms, according to their level of fibrosis. Arm A (consists of chronic HCV genotype 1 infected participants with early stages of liver fibrosis): participants will receive a combination therapy of SMV 150 milligram (mg), DCV 60 mg and SOF 400 mg once daily for 6 weeks. Arm B (consists of chronic HCV genotype 1 infected participants with cirrhosis): participants will receive a combination therapy of SMV 150 mg, DCV 60 mg and SOF 400 mg once daily for 8 weeks. A sub-study will be performed at a selected study site, where only participants who will be eligible to participate in both the main study and the sub-study will be enrolled. Intra-hepatic and plasma HCV ribonucleic acid (RNA) levels; intra-hepatic, peripheral innate and adaptive immune responses during the treatment, will be assessed in the sub-study. Participants' safety will be monitored throughout the study.

- •Participants of Arm B should have evidence of cirrhosis, defined by a FibroSURE score >0.75 and APRI score >2, OR a previous (historical) biopsy documenting a METAVIR score F
- •In addition, participants should have absence of esophageal varices or presence of small (grade 1) esophageal varices determined by upper gastrointestinal endoscopy, and absence of findings indicative of hepatocellular carcinoma in an ultrasonography
- •HCV treatment-naive, defined as not having received treatment with any approved or investigational drug for chronic HCV infection
- •Pegylated interferon (PegIFN) and ribavirin (RBV) eligible, defined as not having any contraindication to the use of PegIFN and RBV, in line with the prescribing information for each compound
排除标准
- •A. Main Study:
- •Co-infection with HCV of another genotype than genotype 1 and/or human immunodeficiency virus (HIV) type 1 or 2 (positive HIV-1 or HIV 2 antibody test at Screening)
- •Any evidence of liver disease of non-HCV etiology. This includes, but is not limited to, acute hepatitis A infection, hepatitis B infection (hepatitis B surface antigen positive), drug- or alcohol-related liver disease, autoimmune hepatitis, hemochromatosis, Wilson's disease, alpha-1 antitrypsin deficiency, non-alcoholic steatohepatitis, primary biliary cirrhosis, or any other non-HCV liver disease considered clinically significant by the Investigator
- •Evidence of clinical hepatic decompensation or presence of grade 2/3 esophageal varices
- •Any of the protocol defined laboratory abnormalities
- •B. Sub-study:
- •Presence of coagulopathy (hemophilia) or hemoglobinopathy (including sickle cell disease, thalassemia)
- •Use of any anti-coagulant (for example, warfarin, heparin) or anti-platelet medications within 1 week of the Screening visit
- •Any of the protocol defined laboratory abnormalities
