safety and pk study of nov-205 to treat chronic hcv who fail standard therapy

Conditions: Hepatitis C

Summary: the purpose of this research trial is to find out whether nov-205 is well tolerated compared to placebo (salt water) in people with hepatitis c. in addition, this trial will test how nov-205 is absorbed by your body after single and multiple doses of the trial drug, and it will look for early signs of therapeutic activity (decreases in indicators in the blood for the hepatitis c virus and for liver damage). this is known as pharmacokinetics (pk). nov-205 is an experimental drug. "experimental" means that the trial drug is currently being tested and is not approved for sale in the united states by the food and drug administration (fda). however, nov-205 has been approved by the russian federation for treatment of liver diseases including hepatitis c. clinical studies in that country showed that subjects treated with nov-205 alone had decreased indicators in the blood for the hepatitis c virus and for liver damage.

this phase 1b trial aims to evaluate the pharmacokinetic profile of nov-205, and in comparison to placebo, identify early signs of antiviral activity (with a quantitative reduction of \>0.5 log10 in serum hcv rna level (elbeik, 2004)) and establish a safety profile of nov-205 as monotherapy in subjects with chronic hcv who are non-responders to treatment with pegylated interferon plus ribavirin. this trial will also explore the effect of nov-205 on serum biochemical markers of liver damage (e.g. alanine aminotransferase, alt) as indications of biologic activity. results of this trial will guide the design of future phase 2 studies of nov-205 in chronic hepatitis c subjects.

Eligibility criteria:
inclusion criteria: * a serum hcv rna level of \>100,000 iu/ml using a quantitative, branched-chain-dna (bdna)-based assay (lower limit of quantitation = \~650 iu/ml) or other equally sensitive quantitative methods. * infection with genotype 1 hcv * documented failure to respond to treatment (defined as a patient who did not achieve an early viral response (evr) (≥2 log reduction in serum hcv rna or undetectable hcv rna after 12 weeks of treatment) or is serum hcv rna positive after 24 weeks of treatment with pegylated interferon plus ribavirin for hepatitis c. * women of childbearing potential willing to use two acceptable methods of birth control during trial participation or are sterile or post-menopausal (defined as not having a menstrual cycle for greater than two years) * sexually active male subjects are practicing acceptable methods of contraception during trial participation * have the ability to understand the requirements of the trial, have provided written informed consent, and agree to abide by the trial restrictions and to return for the required assessments * the subject must be able to self administer daily subcutaneous injections or their caregiver must be able to administer daily subcutaneous injections exclusion criteria: * clinical, laboratory, or histological evidence of liver cirrhosis * evidence of hepatic decompensation (presence of or a history of ascites, hepatic encephalopathy, variceal bleeding, or hepatocellular carcinoma) * co-infection with human immunodeficiency virus (hiv) or active hepatitis b virus (hbv) (as determined by presence of hepatitis b surface antigen (hbsag) * have received pegylated interferon and/or ribavirin within the 60 days prior to randomization * any known preexisting medical condition that could interfere with the subject's participation in and completion of the protocol * pregnant female or nursing mother
