Details and patient eligibility

About

Open pharmacokinetic study with 5 parallel groups and two treatment phases (bemiparin 3,500 IU multiple dose and bemiparin 115 IU/kg single dose). The bemiparin pharmacokinetic profile will be assessed by measuring its effects on the coagulation cascade. Plasma anti-Xa activity (measured using chromogenic amidolytic assay) in IU per milliliter will be the primary endpoint to assess the pharmacokinetic profile of bemiparin.

Inclusion criteria

Non-elderly healthy volunteers (Group I):

Male or female subjects aged between 18 and 65 years
body weight, clinical history, physical examination, vital signs (systolic and diastolic blood pressure, heart beat rate and body temperature), ECG and laboratory tests (hemogram and biochemistry) within normal range
without evidence of significant organic or psychiatric illness
who have accepted to participate in the study and have signed the written informed consent.

Patients with renal insufficiency (Groups II, III and IV):

Male or female subjects aged between 18 and 65 years, who will be assigned to one of the following groups according to renal function:
- Group II: mild renal insufficiency (creatinine clearance > 50 to 80 ml/min);
- Group III: Moderate renal insufficiency (creatinine clearance: 30 to 50 ml/min);
- Group IV: Severe renal insufficiency (creatinine clearance < 30 ml/min). The degree of renal insufficiency will be calculated on the basis of determination of creatinine clearance measuring total urinary output over a 24-h period and serum creatinine levels. Urine samples will be collected no more than 2 weeks before the first experimental period.
Patients with renal insufficiency must have a stable renal function during the 3 months before their inclusion in the study.
They must have a body weight between 45 and 110 Kg.
They have to accept to participate in the study and have signed the written informed consent.

Elderly healthy volunteers (Group V):

Male or female subjects aged > 65 years old who fulfill with the remaining inclusion criteria specified for non-elderly healthy volunteers.
