NCT01823510

Brief Summary

The purpose of this study is to determine whether treatment with ticagrelor + aspirin is more effective than treatment with clopidogrel + aspirin in patients with type-2 diabetes. Both treatments will be given (separately) to all subjects as a one-time loading dose (i.e. higher than a normal daily dose), followed by daily dose for the next 5 to 7 days. Effectiveness of treatment will be measured with specialized blood tests before the loading dose, at two time-points after the loading dose, and once after the last daily dose.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosed with type-2 diabetes being treated with oral or parenteral hypoglycemic therapy or both.
  • Have not had thienopyridine therapy for at least 30 days before the study.
  • Are of legal age (at least 18 years of age but less than 75 years of age) and competent mental condition to provide written informed consent.
  • For women of child-bearing potential only test negative for pregnancy at the time of enrollment.

You may not qualify if:

  • Have a defined need for thienopyridine therapy.
  • Subjects within ≤30 days of coronary artery bypass graft (CABG) surgery or percutaneous coronary intervention (PCI).
  • Known glycosylated hemoglobin (HbA1c) ≥10 mg/dL within last 3 months prior to study entry.
  • Have received fibrinolytic therapy \<48 hours prior to randomization.
  • Have active internal bleeding or history of bleeding diathesis.
  • Have clinical findings that are, in the judgment of the investigator, associated with an increased risk of bleeding.
  • Have history of ischemic or hemorrhagic stroke, transient ischemic attack (TIA) or intracranial neoplasm, arteriovenous malformation, or aneurysm.
  • Have an International Normalized Ratio (INR) known to be \>1.5 within 1 week of study entry.
  • Have a known platelet count of \<100,000/mm3 within 1 week of study entry.
  • Have known anemia (hemoglobin \[Hgb\] \<10 gm/dL) within 1 week of study entry.
  • Are receiving or will receive oral anticoagulation or other antiplatelet therapy (other than ASA) that cannot be safely discontinued for the duration of the trial.
  • Are receiving daily treatment with non-steroidal anti-inflammatory drugs (NSAIDS) that cannot be discontinued.
  • Have a concomitant medical illness that in the opinion of the investigator may interfere with or prevent completion in this study.
  • Have known severe hepatic dysfunction (e.g., cirrhosis or portal hypertension).
  • Have a history of intolerance or allergy to ASA or approved thienopyridines (ticlopidine or clopidogrel).
