About
Primary Objective:
- To assess the pharmacokinetic (PK) and pharmacodynamic (PD) parameters of Semuloparin [AVE5026] (assessed from the anti-Xa activity of Semuloparin) in children in order to determine the dose to be assessed in a clinical efficacy/safety study in this population.
Secondary Objective:
- To assess the tolerability of Semuloparin when administered at a weight-adjusted, once daily dose for up to 30 days in patients less than 18 years of age with central venous line.
Full description
The maximum study duration for a participant was 68 days broken down as follows:
- Screening period: up to 6 days,
- Treatment period: minimum 6 days and maximum 30 days,
- Follow-up period with an end of study visit performed 4 weeks (30 +/-2 days) post treatment.
Enrollment staggered by age group starting with the older children (≥12 years). In each younger age group, enrolment was planned to initiate only following a review by the Data Monitoring Committee (DMC) of the clinical safety data and available PK and PD data from the first 3 out of 7 children from the previous older age group. Enrollment of infants <3 months was planned to initiate after recruitment of all patients ≥3 months had been completed and all data analyzed by the DMC.

- Patient hospitalized or able to receive daily injection for at least 6 days and provide plasma samples at Day 4, 5 and 6 at the pre-specified time points;
- Written informed consent signed by legal representative(s) in accordance with local regulation, and possibly assent form by the child (country/age specific).
Exclusion criteria:
- Patient for whom anticoagulant therapy was contraindicated;
- Planned treatment with other antithrombotic agents within 2 weeks prior to enrolment and during the course of the study;

- Recent (less than 3 weeks prior to enrollment ) brain, spinal or ophthalmologic surgery;
- Uncontrolled hypertension characterized by a sustained systolic pressure or diastolic pressure greater than 2 standard deviations above the age-related norm;
- Severe hepatic disease (e.i. more than 2.5 times the upper limit for age of hepatic enzymes);
- Severe renal insufficiency (estimated creatinine clearance <30 ml/min using the Schwartz formula);
- Any condition that, in the opinion of the Investigator, would have exposed the patient to an unfavorable risk/benefit ratio;
- Presence or history of drug hypersensitivity;
- Any patient currently involved in another clinical trial with an investigational drug according to applicable regulations;
- Any patient or parent(s)/legal guardian(s) who, in the judgment of the Investigator, was likely to be noncompliant during the study, or unable to cooperate because of a language problem or poor mental development;
- Any patient or parent(s)/legal guardian(s) who could not be contacted in case of emergency;
- Pregnant or breast-feeding female;
