  Purpose

Primary objective:

  • to characterize the pharmacokinetic and the pharmacodynamic profile after intravenous bolus injection of unfractionated heparin (UFH) after repeated sc 100 IU anti-Xa/kg (corresponding to 1 mg/kg) twice a day during 2.5 days (every 12±2hrs) administrations of enoxaparin in Caucasian healthy subjects.

Secondary objective(s):

  • to compare the pharmacokinetic and the pharmacodynamic profile between 3 different timing of administration of the UFH
  • to assess the tolerability of the different anticoagulation protocols

Primary Outcome Measures:
  • Concentration-time profiles of anti-Xa and anti-IIa levels [ Time Frame: At baseline (Day 2) after the morning enoxaparin injection and at day 3 from pre-dose of enoxaparin and lasting until 14 hours after the enoxaparin injection. ]

Secondary Outcome Measures:
  • Effect-time profiles of ACT, TGTppp and TGTprp [ Time Frame: At baseline (Day 2) after the morning enoxaparin sc injection and at day 3 from pre-dose of enoxaparin and lasting until 14 hours after the enoxaparin injection. ]
  • PFA100 levels measured [ Time Frame: At pre-dose, 4h and 14h post dose of enoxaparin ]
  • Documentation of adverse event, physical examination, clinical laboratory safety, vital signs and ECG recording at prespecified time-points. [ Time Frame: during the entire study ]

Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Caucasian
  • Male and female subjects, between 40 and 60 years of age

Health Status:

  • Certified as healthy by a comprehensive clinical assessment (detailed medical history and complete physical examination)
  • Subject with hypertension, hypo- or hyperthyroidism or dyslipidemia will be included if their concomitant pathology is well-controlled by treatment for at least one year
