Comparison of Prasugrel and Clopidogrel in Very Elderly and Non-Elderly Patients With Stable Coronary Artery Disease (GENERATIONS)

27 settembre 2012 aggiornato da: Eli Lilly and Company

A Pharmacokinetic and Pharmacodynamic Comparison of Prasugrel and Clopidogrel in Very Elderly Versus Non-Elderly Aspirin-Treated Subjects With Stable Coronary Artery Disease

The 5-milligram (mg) maintenance dose (MD) of prasugrel in very elderly patients with coronary artery disease produces a pharmacodynamic response within the same therapeutic range as 10-mg MD in non-elderly patients.

  • Any planned surgical procedure or any coronary revascularisation (surgical or percutaneous) planned within 60 days following randomisation
  • Any known contraindication to treatment with an antiplatelet agent
  • Significant hypertension at the time of screening or randomisation
  • Clinically significant out-of-range values for platelet count or haemoglobin at screening, in the investigator's opinion, or results of clinical laboratory tests at the time of screening that are judged to be clinically significant for the study population, as determined by the investigator
  • Prior history or presence of significant bleeding disorders, abnormal bleeding tendency, or personal history of coagulation or bleeding disorders
  • Prior history or clinical suspicion of cerebral vascular malformations, intracranial neoplasm, Transient Ischemic Attack (TIA) or stroke
  • Prior history of thrombocytopenia or thrombocytosis

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Maximum Platelet Aggregation (MPA) to 20 Micromoles (μM) Adenosine Diphosphate (ADP) as Measured by Light Transmission Aggregometry (LTA) From Baseline to 12 Days of Therapy in the First Treatment Period
Lasso di tempo: Baseline, 12 days
Maximum Platelet Aggregation (MPA) to 20 μM ADP was assessed by light transmission aggregometry (LTA), an assay that measures platelet aggregation by determining the amount of light transmitted through a cuvette containing the platelet-rich plasma stimulated with a platelet activator, such as ADP, relative to platelet-poor plasma (100% light transmittance). Lower MPA values reflect stronger platelet inhibition, whereas higher MPA values reflect weaker inhibition.
Baseline, 12 days

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Vasodilator-associated Stimulated Phosphoprotein (VASP) From Baseline to 12 Days of Therapy
Lasso di tempo: Baseline, Day 12
Vasodilator-associated stimulated phosphoprotein (VASP) phosphorylation levels, expressed as the platelet reactivity index (PRI), reflect the degree of thienopyridine-mediated P2Y12 receptor inhibition. A lower PRI reflects stronger inhibition of P2Y12, whereas a higher PRI reflects weaker inhibition of P2Y12.
Baseline, Day 12
Change in VerifyNow P2Y12 Reaction Units (PRU) From Baseline to 12 Days of Therapy
Lasso di tempo: Baseline, Day 12
The Accumetrics VerifyNow® P2Y12 assay measures platelet aggregation in whole blood and is reported in P2Y12 reaction units (PRU). PRU report the extent of P2Y12 receptor-mediated platelet aggregation calculated as a function of the rate and extent of platelet aggregation in the presence of adenosine phosphate ADP. A lower PRU reflects stronger inhibition of P2Y12, whereas a higher PRU reflects weaker inhibition of P2Y12.
Baseline, Day 12
Active Metabolite Blood Levels to Drug Exposure as Measured by Pharmacokinetics (PK) Through 4 Hours After Dosing
Lasso di tempo: Baseline up to 4 hours post-dose
A descriptive pharmacokinetic-pharmacodynamic (PK-PD) analysis comparing prasugrel and clopidogrel active metabolite exposures to MPA in response to 20 µM ADP (by LTA) was conducted as originally intended; however, the graphic output from that analysis is not possible here. Therefore, the PK portion is presented here as AUC and the PD portion is presented in Secondary Outcome Measure #5. AUC was calculated through the last scheduled sampling time of 4 hours [AUC (0-4)] or through the sampling time of the last quantifiable concentration prior to 4 hours. AUC values were denoted AUC(0-tlast) in both instances.
Baseline up to 4 hours post-dose
Change From Baseline in Maximum Platelet Aggregation (MPA) as Measured by Light Transmission Aggregometry (LTA) From Baseline at Day 12 of Therapy
Lasso di tempo: Baseline, Day 12
Maximum Platelet Aggregation (MPA) to 20 μM ADP was assessed by light transmission aggregometry (LTA), an assay that measures platelet aggregation by determining the amount of light transmitted through a cuvette containing the platelet-rich plasma stimulated with a platelet activator, such as ADP, relative to platelet-poor plasma (100% light transmittance). A lower MPA reflects stronger platelet inhibition, whereas a higher MPA reflects weaker inhibition.
Baseline, Day 12
