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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Primary hypothesis: Percentage IPA after 20uMol/ADP at 30' will be superior in the tirofiban arm (as aggregate) versus prasugrel alone arm Percentage IPA at 30' after 20uMol/ADP 90%±15 and 80%±15 in the tirofiban and prasugrel alone arm, respectively. For a power of 90% and an alpha error set at 5%, 50 patients per group have to be recruited.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage IPA after 20uMol/ADP at 30' will be superior in the tirofiban arm (as aggregate) versus prasugrel alone arm
Time Frame: 30 minutes
Platelet aggregation (PA) will be performed as previously reported [J Am Coll Cardiol 2006;48:2178-85]. Blood samples anticoagulated with 0.129 mol/l sodium citrate will be collected for platelet reactivity. Platelet-rich plasma, obtained by centrifuging whole blood for 10 min at 200 g, will be stimulated with 5 and 20 µmol/l adenosine 5'-diphosphate (ADP) (Alfa Wasserman, Bologna, Italia) and aggregation will be assessed using a AggRAM Advanced Modular System light transmittance aggregometer.
30 minutes

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

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.
