Trial Outcomes & Findings for Cangrelor to Clopidogrel or Prasugrel Transition Study (NCT NCT01979445)

NCT ID: NCT01979445

Last Updated: 2020-02-26

Results Overview

A reference point for prasugrel or clopidogrel was chosen for comparison and designated at 6 or 5.5 hrs after the administration of prasugrel or clopidogrel as the reference for the effect of the oral drug. Platelet function was assessed using light transmittance aggregometry (LTA). LTA measures the aggregation or cross linking of platelets by fibrinogen and requires the activation of platelets plus the binding of fibrinogen. The extent of aggregation was expressed as % aggregation in response to 20 micromolar (μM) adenosine diphosphate (ADP) at 300 seconds (sec) (final/terminal aggregation response).

PRIMARY outcome

Timeframe: Day 1 at 1, 1.5, 2, or 2.5 hrs after administration of prasugrel or clopidogrel (reference) and Day 1 at 1.75 and 2 hrs after initiation of cangrelor infusion

Population: Participants treated with cangrelor and prasugrel or clopidogrel were used for the analysis and presentation of data.

A reference point for cangrelor was chosen for comparison and designated as the administration time of prasugrel 60 mg or clopidogrel 600 mg (2.5, 2, 1.5, or 1 hrs). Platelet function was assessed using LTA. LTA measures the aggregation or cross linking of platelets by fibrinogen and requires the activation of platelets plus the binding of fibrinogen.

Population: Participants treated with cangrelor and prasugrel or clopidogrel were used for the analysis and presentation of data.

A reference point for prasugrel or clopidogrel was chosen for comparison and designated at 6 or 5.5 hrs after the administration of prasugrel or clopidogrel as the reference for the effect of the oral drug. Platelet function was assessed using the VerifyNow P2Y12 assay. The VerifyNow P2Y12 assay measures the aggregation or cross linking of platelets by fibrinogen and requires the activation of platelets plus the binding of fibrinogen. The extent of aggregation was assessed by platelet reaction units (PRU), determined by the VerifyNow P2Y12 assay. The VerifyNow P2Y12 assay is designed to directly measure the effects of drugs on the P2Y12 receptor, using prostaglandin E1 in addition to ADP to increase intraplatelet cyclic adenosine monophosphate (cAMP). Platelet reactivity was expressed in PRU.

SECONDARY outcome

Timeframe: Screening through the follow-up period (5 to 7 days after Day 1)

Population: Safety Population included all participants who received at least 1 dose of study drug.

Bleeding was assessed by history, physical exam, and complete blood count (CBC) that was performed on study Day 1. Reports of bleeding were to be evaluated by performance of a CBC. Participants were assessed for bleeding events in accordance with the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) scale. The severity of bleeding events by GUSTO Criteria is defined as the following: * Severe/life-threatening: fatal, intracranial hemorrhage, or if hemodynamic compromise results * Moderate: transfusion required * Mild: no transfusion or hemodynamic compromise A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.
