Food Effect Study on Pharmacodynamic and Bioavailability of Clopidogrel 300/75 mg in Healthy Subjects

December 14, 2011 updated by: Sanofi

A Randomized, Placebo-controlled, Two-sequence, Two-period Crossover Study, to Investigate a Potential Food Effect on the Pharmacodynamic and Bioavailability of Repeated Oral Doses of Clopidogrel (300 mg Loading Dose Followed by 75 mg/Day) in Healthy Male Subjects

Primary objective:

  • Investigate the potential food effect on Adenosine diphosphate(ADP)-induced platelet aggregation after 5-day repeated doses of clopidogrel (300 mg loading dose followed by 4 days 75 mg/day) in healthy subjects

Secondary objectives are to investigate the potential food effect on:

  • ADP-induced platelet aggregation after 300 mg loading dose of clopidogrel
  • Pharmacokinetic profiles of clopidogrel and its active metabolite after 5-day repeated doses of clopidogrel

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The total duration per subject is 8-9 weeks broken down as follows:

  • Screening: 2 to 21 days before the first dosing
  • Fed period: 7 days including 5 treatment days
  • Washout: at least 14 days after last dosing
  • Fasted period: 7 days including 5 treatment days
  • End of study: 7 to 10 days after the last dosing

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

Healthy male subjects:

  • as determined by medical history, physical examination including vital signs and clinical laboratory tests
  • with a body weight between 50kg and 95 kg and a Body Mass Index (BMI) between 18 and 30 kg/m2

Exclusion Criteria:

  • Evidence of inherited disorder of coagulation/hemostasis functions
  • Smoking more than 5 cigarettes or equivalent per day
  • Abnormal hemostasis screen

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
Time Frame
Maximum platelet aggregation intensity (MAI) induced by Adenosine diphosphate (ADP) 5µM after 5 days treatment
Time Frame: Day 5 of each period
Day 5 of each period

Secondary Outcome Measures

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.
Outcome Measure
Time Frame
Maximum platelet aggregation intensity (MAI) induced by ADP 5µM after loading dose and high fat breakfast
Time Frame: 6 hours and 24 hours after first dosing of each period
