Pegasys and Copegus for Asian Patients With Treatment-naive Hepatitis C Genotypes 6, 7, 8, 9

Completed · Phase 4

Conditions studied: Chronic Hepatitis C, Asian Americans, Novel Genotypes, Treatment

In brief

The purpose of this research study is to test the safety, tolerability, and effectiveness of the drugs Pegasys and Copegus when used for hepatitis C genotypes 6, 7, 8, and 9. Patients are randomly assigned (by chance) to either Treatment Group A (Pegasys and Copegus for 24 weeks) or Treatment Group B (Pegasys and Copegus for 48 weeks).

You may qualify if…

• The subject must meet the following criteria for entry.
• Subject must be willing to give written informed consent and be able to adhere to dose and visit schedules.
• Adult subjects 18-70 years of age of both gender and any race as long as they have HCV genotype 6, 7, 8, and 9.
• Serum positive for HCV-RNA by PCR (qPCR) assay, or bDNA
• Liver biopsy within 24 months prior to entry to this protocol with a pathology report confirming that the histological diagnosis is consistent with chronic hepatitis C with stage II or more fibrosis. Biopsy must be scored or be re-read to score fibrosis stage and grade and severity of steatosis.
• Compensated liver disease with the following minimum hematologic, biochemical, and serologic criteria at the Entry Visit (WNL = within normal limits).
• Hemoglobin (Hb) greater than or equal to12 gm/dL for women and 13 gm/dL for men.
• White blood cell count (WBC) greater than or equal to 2,000/mm3
• Platelets (PLT) greater than or equal to 90,000/mm3
• Direct bilirubin (DB) less than or equal to 1.0
• Indirect bilirubin (IB) = WNL or greater than or equal to 3.0 mg/dL if this is due to non-hepatitis related factors such as Gilbert's disease.
• Creatinine (Cr) clearance greater than or equal to50 mL/minute or serum Cr greater than or equal to 1.5x UNL at screening.
• Fasting glucose (FBS) less than or equal to160 mg/dL and Hb A1c greater than or equal to 8.5% for diabetic subjects (whether on medication or diet controlled).
• Thyroid Stimulating Hormone (TSH) = WNL (Subjects requiring medication to maintain TSH levels in the normal range are eligible if all other inclusion/exclusion criteria are met.)
• Serum anti-HIV = negative
• Serum HBsAg = negative
• Abdominal ultrasound negative for liver masses within 3 months prior to entry. Patients without cirrhosis or transition to cirrhosis may have there imaging studies done within 12 months of study entry.
• Alpha-fetoprotein (AFP) less than or equal to 20 ng/mL obtained within 3 months prior to entry. Patients with 20 ng/mL less than or equal to AFP less than or equal to 100ng/mL may be enrolled after a normal biphasic abdominal CT within the previous 3 months if patients have Stage III/IV fibrosis and after a normal ultrasound if patients have Stage I/II fibrosis. If AFP is more than 100 but less than 200 ng/dL, all patients need to have a negative biphasic CT within 3 months.
• Female subjects must not be breast-feeding.
• A pregnancy test must be obtained within 24 hours to the first dose of study drugs and must be negative.
• Additionally, all fertile males and females must use two reliable forms of effective contraception (combined) during treatment with study drugs and 6 months after treatment completion.
• Acceptable forms of contraception may include intrauterine device, oral contraceptives, progesterone implanted rods [Norplant], medroxyprogesterone acetate [Depo-Provera], surgical sterilization, barrier method [diaphragm + spermicide or condom + spermicide]

You may not qualify if…

• The subject will be excluded from entry if any of the following criteria apply:
• Women who are pregnant or breast feeding.
• Male partners of women who are pregnant.
• Suspected hypersensitivity to interferon, PEG-interferon or Copegus.
• Treatment with any investigational drug within 45 days of entry to this protocol.
• Therapy with any systemic anti-viral, anti-neoplastic or immunomodulatory treatment greater than or equal to6 months prior to the first dose of study drug, except PEG-IFN alfa-2b and ribavirin. This includes amantadine, mycophenolate mofetil, thymosine alpha, viramidine, levovirin, supraphysiologic doses of steroids (greater than or equal to 10 mg/d for greater than or equal to 14 consecutive days of prednisone or equivalence) and radiation, exception: patients who have had a limited (greater than or equal to 7 day) course of acyclovir or valacyclovir for herpetic lesions more than 1 month prior to the first administration of test drug are not excluded.
• Any other cause for the liver disease other than chronic hepatitis C including but not limited to:
• Co-infection with HBV
• Hemochromatosis (iron deposition greater than or equal to2+ or severe in liver parenchyma)
• Alpha-1 antitrypsin deficiency
• Wilson's disease
• Autoimmune hepatitis
• Alcoholic liver disease
• Significant obesity-induced liver disease (elevated ALT with BMI greater than or equal to 30)
• Drug-related liver disease
• Hemophilia or any other condition that would prevent the subject from having a liver biopsy, including anticoagulant therapy.
• Hemoglobinopathies (e.g., Thalassemia) with significant anemia.
• History or other evidence of decompensated liver disease or a Child-Pugh score 6. Coagulopathy, hyperbilirubinemia, hepatic encephalopathy, hypoalbuminemia, ascites, and bleeding from esophageal varices are conditions consistent with decompensated liver disease.
• Patients with history of hepatocellular carcinoma.
• Any known preexisting medical condition that could interfere with the subject's participation in and completion of the protocol such as:
• A history of preexisting psychiatric condition, especially severe depression, or a history of severe psychiatric disorder, such as major psychoses, suicidal ideation and/or suicidal attempt are excluded. Severe depression would include the following: (a) subjects who have been hospitalized for depression, (b) subjects who have received electroconvulsive therapy for depression, or (c) subjects whose depression has resulted in a prolonged absence of work and/or significant disruption of daily functions. Subjects with a history of mild depression may be considered for entry into the protocol provided that a pretreatment assessment of the subject's mental status supports that the subject is clinically stable. The Investigator will formulate a management plan for each of the subjects that will become a part of the subject's medical record. The management plans may be developed in conjunction with a health care professional trained in psychology. For these subjects, the Investigator will review the subject's mental status at every visit.
• CNS trauma or active seizure disorders requiring medication.
• Significant cardiovascular dysfunction within the past 12 months (e.g., angina, congestive heart failure, recent myocardial infarction, severe uncontrolled hypertension or significant arrhythmia). Subjects with ECG showing clinically significant abnormalities.
• Poorly controlled diabetes mellitus.
• Chronic pulmonary disease (e.g., chronic obstructive pulmonary disease), documented pulmonary hypertension.
