Detaillierte Beschreibung
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".

Beschreibung
Inclusion Criteria:
- Willing and able to provide written informed consent;
- Male or female, age≥18 years;
A female subject is eligible to enter the study if it is confirmed that she is:
- Of non-childbearing potential (i.e., women who have had a hysterectomy, have both ovaries removed or medically documented ovarian failure, or are postmenopausal-women > 50 years of age with cessation (for≥12 months) of previously occurring menses), or
- Of childbearing potential (Women≤50 years of age with amenorrhea will be considered to be of childbearing potential). These women must have a negative serum pregnancy test at screening, and must use specific contraceptive methods from screening until 4 weeks after last dose of study drugs, such as complete abstinence from intercourse, vaginal ring, cervical cap or contraceptive diaphragm, IUD, etc.
- All male study subjects must agree to consistently and correctly use specific contraceptive methods with their female partner from screening until 4 weeks after last dose of study drugs(except of surgical sterilization), such as complete abstinence from intercourse, condom, and their female partner use contraceptives , vaginal ring , cervical cap or contraceptive diaphragm, IUD, etc.
- Male subjects must agree to refrain from sperm donation from the date of screening until 4 weeks after the last dose of study drugs;
- Body mass index (BMI)≥18.0 and≤32.0 kg/m2, and Weight≥40 kg;
Confirmation of chronic HCV infection documented by either:
- A positive anti-HCV antibody test or positive HCV RNA or positive HCV genotyping test at least 6 months prior to the Baseline/Day 1 visit, or
- A liver biopsy performed prior to the Baseline/Day 1 visit with evidence of chronic HCV infection.
- Serological detection of anti-HCV antibodies was positive at screening;
- HCV RNA≥1×104 IU/mL at Screening;
- HCV genotype 1a, 1b, or mixed 1a/1b at screening as determined by the Central Laboratory;
Classification as treatment naive or treatment experienced:
- 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);
- 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:
i) Non-Responder: Decrease of HCV RNA<2 log at week 12 compared to baseline; ii) Partially-Responder: Decrease of HCV RNA>2 log at week 12 compared to baseline, and detectable HCV RNA levels within week 12 and week 24; iii) Breakthrough/Relapse: Subject achieved undetectable HCV RNA levels (HCV RNA < LLOQ) during treatment, but did not achieve sustained virologic response (SVR); iv) Intolerance: Subjects have discontinued interferon-based treatment due to intolerance which proved by chief complaint or medical records.
Absence of cirrhosis is defined as any one of the following:
- Liver biopsy within 2 years of Screening or at Screening showing absence of cirrhosis (e.g. Metavir score=0-3 or Ishak score<5), or
- Fibroscan within 6 months of Screening or at Screening with a result of ≤12.5 kPa.
liver biopsy results will supersede fibroscan results and be considered definitive.
- Subject must be able to comply with the dosing instructions for study drug administration and able to complete the study schedule of assessments.
Exclusion Criteria:
Subjects who meet any of the following exclusion criteria are not to be enrolled in this study:
Current or prior history of any of the following:
- Clinical hepatic decompensation (i.e., ascites, encephalopathy or variceal hemorrhage);
- Chronic liver disease of a non-HCV etiology (Including but not limited to hemochromatosis, Wilson's disease,alfa-1 antitrypsin deficiency);
- Significant cardiac disease(Including but not limited to myocardial infarction, bradycardia) ;
- Significant pulmonary disease;
- Malabsorption syndrome or gastrointestinal disorder or post operative condition that could interfere with the absorption of the study drug;
- Central nervous system trauma, epilepsy, stroke or transient ischemic attack;
- Psychiatric illness or psychological disease or relevant medical history;
- Malignancy diagnosed before signing the informed consent form ( except for specific cancers that have been cured by surgical resection (basal cell skin cancer, etc) or cervical carcinoma in situ are allowed). subjects under evaluation for malignancy are not eligible;
- Solid organ transplantation;
- Subjects have any other medical disorder that may interfere with subjects treatment, assessment or compliance with the protocol.
Subjects has the following laboratory parameters at screening:
- ALT > 10×the upper limit of normal (ULN);
- AST > 10×ULN;
- Total bilirubin> 1.5 × ULN;
- Albumin< 3.5 g/dL;
- 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;
- INR > 1.5 x ULN;
- Hemoglobin<11 g/dL for female subjects; <12 g/dL for male subjects;
- Platelets<90 x109/L;
- Neutrophil absolute count< 1.5 ×109/L;
- HbA1c > 8.5%;
- Creatinine clearance (CLcr) <50 mL /min as calculated by the Cockcroft-Gault equation;
- HBsAg serology test results were positive;
- HIV antibody test results were positive.
- Screening ECG with clinically significant abnormalities;
- Prior exposure to approved or experimental HCV-specific direct-acting antiviral agent;
- Use of any prohibited concomitant medications;
- Significant drug allergy, or known hypersensitivity to DAG181, SOF and its metabolites, or formulation recipients;
- A positive drug screen at screening will exclude subjects unless it can be explained by non-prescription drug or prescribed medication; the diagnosis and prescription must be approved by the investigator;
- Pregnant or nursing female or male with pregnant female partner.
