简要总结

The major goal of this project is to identify the role of the immune responses in the emergence of protease inhibitor mutants during therapy.

详细描述

Objective 1: Evaluate the role of the immune responses in determining the emergence of HCV NS3 resistance mutation during protease inhibitor therapy

Hypothesis 1 (HT 1): Low HLA binding to peptides containing protease inhibitor resistance mutations is associated with the emergence of protease inhibitor mutants during therapy and failure of the treatment.

Hypothesis 2 (HT 2): A hole in T cell repertoire may allow emergence of protease inhibitor mutants during protease inhibitor therapy which leads to loss of the immune responses to these mutants and failure of treatment.

入选标准

  • All chronically HCV-infected patients who fail peg-IFN and RBV therapy and are eligible for combined treatment with PI therapy will be enrolled. Briefly, this includes:
  • Male or female
  • Age 18 to 65
  • Chronic HCV infection evidenced by liver biopsy or persistent HCV viremia for >6 months
  • Treatment experienced and classified as non-responder or relapser to prior interferon-based therapy.
  • Exclusion criteria:
  • Treatment naïve chronically HCV-infected patients.
  • Patients with a history of inflammatory bowel diseases (IBD) or suspected IBD, autoimmune diseases, including rheumatoid arthritis, and any patients on systemic immunomodulators.
