Study to Assess the Efficacy of 12 Versus 24 Weeks of Extended Treatment in HCV-Genotype 2/3 Patients

2014-08-27 03:25:49 | BioPortfolio

Summary

In this study we intend to treat patients with chronic hepatitis C of genotype 2 or 3 having characteristics associated with poor treatment response for additional 12 or 24 weeks beyond the standard treatment of PEG-IFN alpha-2b plus ribavirin.

The objective of this study is to compare the efficacy of a treatment extension of 12 versus 24 weeks in patients with HCV-genotypes 2 and 3 who are treated with 1.5 µg/kg PEG-IFN alpha-2b and 800-1400 mg ribavirin (standard dose) for 24 weeks (standard duration) and who are not HCV-RNA negative (< 15 IU/ml) after 4 weeks of standard treatment but HCV-RNA negative after 16-24 weeks of standard treatment.

Medical and Biotech [MESH] Definitions

Interferon secreted by leukocytes, fibroblasts, or lymphoblasts in response to viruses or interferon inducers other than mitogens, antigens, or allo-antigens. They include alpha- and beta-interferons (INTERFERON-ALPHA and INTERFERON-BETA).

A ubiquitously expressed heterodimeric receptor that is specific for both INTERFERON-ALPHA and INTERFERON-BETA. It is composed of two subunits referred to as IFNAR1 and IFNAR2. The IFNAR2 subunit is believed to serve as the ligand-binding chain; however both chains are required for signal transduction. The interferon alpha-beta receptor signals through the action of JANUS KINASES such as the TYK2 KINASE.

An interferon regulatory factor that binds upstream TRANSCRIPTIONAL REGULATORY ELEMENTS in the GENES for INTERFERON-ALPHA and INTERFERON-BETA. It functions as a transcriptional activator for the INTERFERON TYPE I genes.

A DEAD box RNA helicase that contains two N-terminal CASPASE ACTIVATION AND RECRUITMENT DOMAINS. It functions as a sensor of viral NUCLEIC ACIDS such as DOUBLE-STRANDED RNA and activates the INNATE IMMUNE RESPONSE by inducing the expression of INTERFERON-ALPHA and INTERFERON-BETA. It may also regulate cell growth and APOPTOSIS.

A multimeric complex that functions as a ligand-dependent transcription factor. ISGF3 is assembled in the CYTOPLASM and translocated to the CELL NUCLEUS in response to INTERFERON signaling. It consists of ISGF3-GAMMA and ISGF3-ALPHA, and it regulates expression of many interferon-responsive GENES.
