Influence of the Proton Pump Inhibitor Omeprazole on the Anti-Platelet of P2Y12 Antagonists in Subjects With Coronary and Peripheral Artery Disease

December 2, 2014 updated by: University of Oklahoma
To determine if prasugrel is superior to clopidogrel in providing adequate antiplatelet effect in a high risk population that requires concomitant use of a Proton Pump Inhibitor (PPI).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

To evaluate if simultaneous treatment with the PPI omeprazole and a P2Y12 receptor antagonist will influence the effect of either clopidogrel and/or prasugrel on platelet reactivity in patients with Coronary Artery Disease (CAD) or Peripheral Arterial Disease (PAD).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

Description

Inclusion Criteria:

  • Adults between 18 and 75 years of age
  • Known or documented history of CAD or PAD prior to enrollment (a diagnosis of CAD may be based upon a positive stress test, prior documented acute coronary event, or angiographic demonstration of CAD; a diagnosis of PAD may be based upon an ankle-brachial index less than 0.9, or angiographic demonstration of PAD)
  • Have not had thienopyridine therapy for at least 15 days before the study
  • Have not had treatment with a PPI for at least 15 days before the study
  • Are taking aspirin (75 to 325 mg/day) for at least one week prior to randomization

Exclusion Criteria:

  • Have New York Heart association (NYHA) Class III and IV congestive heart failure
  • Have any form of coronary revascularization (PCI or coronary artery bypass grafting [CABG]) planned to occur during the study
  • Have undergone PCI or CABG within 30 days of entry to the study
  • Have received a drug eluting endovascular stents in the past year

  • Have any of the following:

    1. Prior history of hemorrhagic stroke or transient ischemic attack (TIA)
    2. Intracranial neoplasm, arteriovenous malformation, or aneurysm
    3. A body weight less than 60 kg
  • Have prior history of GI ulcer disease or bleeding
  • Have symptoms of dyspepsia or gastroesophageal reflux disease
  • Have active internal bleeding or history of bleeding diathesis
  • Have clinical findings, in the judgment of the investigator, associated with an increased risk of bleeding
  • Have an International Normalized Ratio (INR) known to be >1.5 at the time of evaluation
  • Have a platelet count of <100,000/mm3 at the time of screening, if known
  • Have anemia (hemoglobin [Hgb] <10 gm/dL) at the time of screening, if known
  • Are receiving or will receive oral anticoagulation or other antiplatelet therapy (other than aspirin) that cannot be safely discontinued for the duration of the study
  • Are receiving daily treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) that cannot be discontinued or require daily treatment with NSAIDs during the study.
  • Are receiving corticosteroid therapy

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2010

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
