Etude (Study) Phase I Enox - UnFractionated Heparin (UFH)
14. März 2011 aktualisiert von: Sanofi
A Phase I, Pharmacokinetic and Tolerability Study of Intravenous Unfractionated Heparin After Subcutaneous Enoxaparin 1mg/kg Bid Repeated Administration in Healthy Subjects
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

Inclusion Criteria:
- Caucasian
- Male and female subjects, between 40 and 60 years of age
- Body weight between 50 kg and 90 kg if male and between 40 and 80 kg if female with Body Mass Index (BMI) between 18 and 29 kg/m2
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
Normal vital signs after 10 minutes resting in supine position:
- 95 mmHg < systolic blood pressure (SBP) < 140 mmHg;
- 45 mmHg < diastolic blood pressure (DBP) < 90 mmHg;
- 40 bpm < heart rate < 100 bpm.
- Normal 12-lead electrocardiogram (ECG); 120 ms < PR < 220 ms, QRS < 120 ms, QTc ≤ 430 ms for male, 450 ms for female or not considered as clinically significant by the investigator
- Laboratory parameters within the normal range unless the Investigator considers an abnormality to be clinically irrelevant for healthy subjects; hepatic enzymes (aspartate amino-transferase or AST, alanine amino-transferase or ALT) should be strictly below the upper laboratory norm.
- Platelets ≥ 150 000 / mm3
- Mean corpuscular volume (MCV) and gamma glutamyl-transferase (GGT) should be strictly in the normal range of the laboratory

- Non smoker or smoking the equivalent or less than 5 cigarettes a day and able not to smoke during the study hospitalization
- Normal gynecological examination no longer than 12 months before inclusion.
- For female with childbearing potential using an effective contraception method (e.g. intra-uterine device, hormonal contraception, diaphragm and condom) except if postmenopausal for more than 12 months or sterilized for more than three months
- Subject with coagulation test and blood count (including platelets) within the physiological ranges)
Regulations:
- Having given written informed consent prior to any procedure related to the study
- Covered by Health Insurance System and/or in compliance with the recommendations of National Law in force relating to biomedical research
- Not under any administrative or legal supervision
Exclusion Criteria:
Medical history and clinical status:

- Subject with detectable antibody against heparin in the blood
- Any history or presence of clinically relevant cardiovascular, gynecologic (for women), pulmonary, gastro-intestinal, hepatic, renal, metabolic, hematological, neurologic, psychiatric, systemic, ocular or infectious disease that is capable of altering the absorption, metabolism, or elimination of drugs, or of constituting a risk factor when taking the study medication; any acute infectious disease or signs of acute illness; except subject with hypertension, hypo- or hyperthyroidism or dyslipidemia if well-controlled by treatment for at least one year.
- Subject with diabetes or other cardiovascular or metabolic disease
- Subject with INR > 1.5
- Frequent headaches and/or migraine, recurrent nausea and/or vomiting (more than twice a month)
- Blood donation or blood loss within one month before administration
- Symptomatic hypotension whatever the decrease in blood pressure or asymptomatic postural hypotension defined by a decrease in SBP equal to or greater than 20 mmHg within three minutes when changing from the supine to the standing position
