The purpose of this study is to determine if rosiglitazone, a medicine used to treat diabetes, improves response to anti-viral treatment.

Condition Intervention

Drug: Pioglitazone (Actos)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label

Further study details as provided by Brooke Army Medical Center:

Primary Outcome Measures:
  • Improvement in baseline viremia and viral kinetics, and/or pro-inflammatory cytokines decrease, and/or markers of innate immunity are upregulated to position a more favorable response to current CHC therapy. [ Time Frame: 104 days ]

Enrollment: 23
Study Start Date: June 2006
Study Completion Date: September 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: pioglitazone
Treatment with pioglitazone 45 mg a day for 3 months
Drug: Pioglitazone (Actos)
pioglitazone 45 mg a day
No Intervention: No intervention
Monitoring period without pioglitazone for 3 months

Detailed Description:
The aim of the study will be to determine if an insulin sensitizing thiazolidinedione (TZD) improves (1) baseline viremia, (2) enhances viral kinetics, (3) improves cytokine profiles and (4) up regulates innate cellular immunity (presumably adaptive immunity is up regulated as well) as measured by the bioactivity of the collected biomarkers.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

  • Fasting glucose levels > 200 mg/dl
  • Women who are pregnant or breast-feeding
  • No other thiazolidinedione after liver biopsy and/or during the entire study (
  • Hepatitis C of non-genotype 1
  • Suspected hypersensitivity to pioglitazone
  • Any cause for liver disease other than chronic hepatitis C, insulin resistance, or NAFLD, including but not limited to:

    • Hemochromatosis
    • Alpha-1 antitrypsin deficiency
    • Co-infection with HBV
    • Wilson's disease
    • Autoimmune hepatitis
    • Significant alcohol use
    • Drug-related liver disease
  • Any condition that would prevent the subject from having a liver biopsy.
  • Hemoglobinopathies that could potentially compromise patient safety
  • Evidence of advanced liver disease such as history or presence of ascites, bleeding varices, spontaneous encephalopathy.
  • Participants with organ transplants other than cornea and hair transplant.
  • Any known preexisting medical condition that could interfere with the subject's participation in and completion of the protocol such as:

    • 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
    • Substance abuse, such as alcohol, IV drugs and inhaled drugs
    • Alcohol consumption is to be strongly discouraged
    • Seizure disorders not controlled with medication
    • Significant cardiovascular dysfunction within the past 12 months
    • Chronic pulmonary disease with documented pulmonary hypertension
    • Immunologically mediated disease [e.g., inflammatory bowel disease (Crohn's disease, ulcerative colitis)], rheumatoid arthritis, idiopathic thrombocytopenia purpura, systemic lupus erythematosis, autoimmune hemolytic anemia, scleroderma, severe psoriasis, clinical cryoglobulinemia with vasculitis
  • Any medical condition requiring, or likely to require, chronic systemic administration of steroids during the course of the study
  • Evidence of an active or suspected cancer or a history of malignancy where the risk of reoccurrence is ≥ 20% within two years
