Descripción detallada

A phase 2, multicenter, randomized, parallel Assigned, open-label study to explore the safety, tolerability and antiviral activity of DAG181/SOF combination for 12 weeks in adult subjects with chronic genotype 1 HCV infection.

Approximately 120 HCV genotype 1 subjects without cirrhosis will be enrolled, treatment-experienced subjects are ≤20%, all subjects will be randomized (1:1) to one of the following two treatment groups by IWRS (Medidata Balance): a) DAG181 100 mg/ SOF 400 mg once daily for 12 weeks, b) DAG181 200 mg/ SOF 400 mg once daily for 12 weeks. Randomization will be stratified by "treatment-naive" or "treatment-experienced".

    1. Treatment naive is defined as having never been exposed to approved or experimental HCV-specific direct-acting antiviral agents or prior treatment of HCV with interferon (with or without ribavirin);
    2. Treatment experienced is defined as prior treatment failure to a regimen containing interferon (IFN-α,β or Peg-IFN±RBV) that was completed at least 2 months prior to screening. and the subject's medical records must include sufficient detail of prior virologic failure to allow for categorization of prior response, as either:

    9. Solid organ transplantation;
    10. Subjects have any other medical disorder that may interfere with subjects treatment, assessment or compliance with the protocol.

    3. Total bilirubin> 1.5 × ULN;
    4. Albumin< 3.5 g/dL;
    5. AFP>100 ng/mL; If 20 ng/mL≤AFP≤100 ng/mL, a liver ultrasound examination is required to exclude subjects suspected of hepatocellular carcinoma;
    6. INR > 1.5 x ULN;
    7. Hemoglobin<11 g/dL for female subjects; <12 g/dL for male subjects;
    8. Platelets<90 x109/L;
    9. Neutrophil absolute count< 1.5 ×109/L;
    10. HbA1c > 8.5%;
    11. Creatinine clearance (CLcr) <50 mL /min as calculated by the Cockcroft-Gault equation;
    12. HBsAg serology test results were positive;
    13. HIV antibody test results were positive.
  3. Screening ECG with clinically significant abnormalities;
  4. Prior exposure to approved or experimental HCV-specific direct-acting antiviral agent;
  5. Use of any prohibited concomitant medications;
  6. Significant drug allergy, or known hypersensitivity to DAG181, SOF and its metabolites, or formulation recipients;
