NCT00720577

Brief Summary

Part A. The purpose of this study is to assess the effects of 6 weeks of treatment with, simvastatin, losartan or pioglitazone compared to placebo on the RNA expression profile of lower extremity peripheral arterial atherosclerotic plaque. Part B. The effect of simvastatin, losartan or pioglitazone compared to placebo on protein and lipid biomarkers in lower extremity peripheral arterial atherosclerotic plaque.

You may not qualify if:

  • Patient is pregnant, breast-feeding, or expecting to conceive during the study including the 14-day post study follow-up.
  • current condition, therapy, lab abnormality, mental legal incapacitation that in the investigator's judgment might confound the results of the study.
  • Patient is currently participating in or has participated in a study with an investigational compound within 30 days of Visit 1.
  • Patient has donated and/or received blood (including phlebotomy of \>300 mL) within 2 months prior to study.
  • Surgery or significant trauma within 2 months prior to Visit 1.
  • Patient is a user of recreational or illicit drugs or has had a recent history \<1yr drug/alcohol abuse\>2 alcoholic drinks per day).
  • Patient was \<80% compliant with dosing during the placebo run-in period AND, in the opinion of the investigator, believed to be unable to maintain at least an 80% compliance with dosing during the active study dosing period.
  • Patient has history of myocardial infarction, stroke, coronary artery bypass surgery or other coronary, carotid, or cerebral revascularization procedure,unstable angina, or angioplasty within 1 month of Visit 1. - Patient has chronic heart failure defined by New York Heart Association NYHA) Classes III or IV.
  • Known clinically significant AV conduction disturbances or arrhythmias
  • Patient has unstable hypertension (e.g., sitting systolic blood pressure \>160 mm Hg or diastolic \>100 mm Hg) at Visit 1.
  • Any known clinically important bleeding or platelet disorder.
  • Patient has history of ileal bypass, gastric bypass, other significant condition associated with malabsorption.
  • Patient is HIV or hepatitis B positive.
  • Patients with significantly elevated TSH at Visit 1 may be entered after consultation with and approval by the SPONSOR. Patients with a history of hypothyroidism, who are on a stable dose of thyroxine with normal TSH level at Visit 1 may be included.
  • Patients on cyclical estrogen medications (Estrogen Replacement Therapy ERT\] or oral contraceptives). Patients on non-cyclical estrogen replacement therapy or Selective Estrogen Receptor Modulator (SERM) may be included, but must be on a stable dose for at least 8 weeks prior.
