About

Phase II: Exploring the efficacy and safety of different doses of SH229 tablets combined with fixed-dose Daclatasvi dihydrochloride (DCV) tablets in the treatment of adult patients with chronic hepatitis C for 12 weeks, providing a basis for the design and implementation of phase III clinical trials.

Phase III: Confirmation of the efficacy and safety of SH229 tablets combined with Daclatasvi dihydrochloride (DCV) tablets in the treatment of adult patients with chronic hepatitis C for 12 weeks, providing a sufficient basis for drug registration and clinical use.

Full description

It is estimated that China has a population of over 10 million infected with HCV and also a highly variable HCV genotype geographic distribution. A simple, universal, non-genotype-specific treatment regimen is preferred for anti-HCV treatment in clinical practice and public health. The combination regimen of SH229 and DCV is expected to completely suppress HCV replication in subjects chronically infected with HCV and achieve a sustained virologic response.

Inclusion criteria

  • Willing and able to provide written informed consent.

  • Subjects should be able to follow the instructions for the study drug and be able to complete screening, on-treatment, and post treatment assessments.

  • Male or female, age above 18 years

  • Body mass index ( BMI ) between 18 and 32 kg/m2 at Screening.

  • Confirmation of chronic HCV infection, which meets one of the following: (a) positive for anti-HCV antibodies, HCV RNA or HCV genotyping results within ≤ 6 months of screening, or (b) liver biopsy ≤ 12 months of screening.

  • HCV RNA above 10^4 IU/mL at Screening by the Central Laboratory.

  • HCV genotype 1, 2, 4, 5, 6, or indeterminate assessed at Screening by the Central Laboratory.

  • Classification as treatment naïve or treatment experienced (approximately 20% of subjects may be treatment experienced):

    1. Treatment naïve is defined as having never been exposed to approved or experimental HCV-specific direct-acting antiviral agents ( DAA ) or prior treatment of HCV with interferon either with or without RBV.
    2. Treatment experienced is defined as prior treatment failure to a regimen containing IFN-based antiviral (INF-α, β or PEG-IFN ± ribavirin) and met one of the following: (i) Non-Responder: Subject did not achieve undetectable HCV RNA levels while ontreatment,, (ii) Relapse/Breakthrough: Subject achieved undetectable HCV RNA levels duringtreatment but did not achieve SVR, (iii) Terminate the treatment , according to associated-HCV therapy adverse events by subject reported or medical records demonstrated.
  • Cirrhosis Determination (approximately 20% of subjects may have cirrhosis):

    1. Cirrhosis is defined as any one of the following: (i) Fibroscan with a result of >12.5 kPa within ≤ 6 months of screening, (ii) Liver biopsy showing cirrhosis within ≤ 12 months of screening.
    2. Absence of cirrhosis is defined as any one of the following:(i) Fibroscan with a result of ≤ 12.5 kPa within ≤ 6 months of screening, (ii) Liver biopsy showing non-cirrhosis within ≤ 12 months of screening.

Exclusion criteria

  • Exposure nucleotide analogue including HCV NS3-4A inhibitor, HCV NS5B inhibitor or any HCV NS5A inhibitor before baseline/Day 1.
  • Receive IFN-based antiviral therapy within 6 months prior to baseline/day 1.
  • Oral or injection of RBV within 3 months prior to baseline/Day 1.
  • Systemic use of potent immunomodulators (eg, adrenocortical hormone, thymosin alpha, etc.) for more than 2 weeks prior to baseline/day 1, or expected to be exposed to these agents during the study.
  • Use of amiodarone within 2 months before baseline/day 1.
  • Positive for Hepatitis B surface antigen (HBsAg) or anti-human immunodeficiency virus antibody (HIV Ab) at screening.
  • Evidence of decompensatory liver function, including but not limited to total serum bilirubin (TBIL) above twice of the upper limit of normal (ULN), serum albumin (ALB) below 35 g/L or prothrombin activity (PTA) below 60% confirmed on repeated testing, previous or present history of ascites, upper gastrointestinal bleeding and/or hepatic encephalopathy, or with a liver function reserve of Child-Pugh class B or C.
  • Primary liver cancer confirmed or evidenced by serum alfa-fetoprotein (AFP) above 100 ng/ml or liver imaging study showing suspected nodules.
  • liver disease of a non-HCV etiology (e.g. alcoholic liver disease, nonalcoholic steatohepatitis, drug-induced hepatitis, autoimmune hepatitis, Wilson disease or hemochromatosis, etc.).
  • Subjects has the following laboratory parameters at screening: ALT or AST>10×ULN, WBC < 3×109 /L, ANC< 1.5×109 /L(or < 1.25×109 /L for cirrhotics ), PLT< 50×109 /L, Hb < 100 g/L, INR > 1.5×ULN, CLcr < 50 mL/min(calculated by the Cockcroft-Gault equation ).

  • Serious hematologic disorders (e.g. anemia, hemophilia, etc.).
  • Serious kidney diseases (e.g. chronic kidney disease, kidney insufficiency, etc.).
  • Serious gastrointestinal disorders, (e.g. peptic ulcer, colitis, etc.) or post operative condition that could interfere with the absorption of the study drug.
