Appraisal of MDCO-157 and Plavix® Pharmacokinetics and Pharmacodynamics in Healthy Volunteers With an Evaluation (AMPHORE)

February 19, 2018 updated by: The Medicines Company

Appraisal of MDCO-157 and Plavix® Pharmacokinetics and Pharmacodynamics in Healthy Volunteers With an Open-label, Randomized, Cross-over Evaluation: The AMPHORE Study

Following a first, dose ascending study that enrolled 144 normal healthy volunteers (NHVs), this study, to be conducted in approximately 36 NHVs, will provide pertinent information in determining the dose-response of MDCO-157 for platelet aggregation inhibition and P2Y12 receptor inhibition effects and in selection of doses that match the antiplatelet effects of 300 mg PLAVIX® ®. The study will also provide additional data for pharmacokinetics (PK), safety and tolerability of single doses of MDCO-157.

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.

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 45 years (Adult)

Accepts Healthy Volunteers

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
Dose Response of MDCO-157 (3 doses) compared to Plavix 300 mg
Time Frame: 24 hr

To evaluate the dose-response of MDCO-157 (at 3 doses) compared to Plavix (300 mg), using Emax and AUEC with VASP, over 24 hours:

  • Maximum effect of P2Y12 receptor inhibition (Emax) using VASP (flow cytometry)
  • Area under the effect of P2Y12 receptor inhibition time curve (AUEC) using VASP (flow cytometry)
24 hr

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.

Pharmacokinetics (PK) of MDCO-157 and its metabolites
Time Frame: 24 hrs
To determine the pharmacokinetic (PK) of MDCO-157, including clopidogrel, clopidogrel carboxylic acid, and clopidogrel H4 thiol active metabolite in plasma
