Details and patient eligibility

About

Primary: To examine the within subject variability of Clexane (80 mg) in healthy male and female volunteers administered subcutaneously (s.c.) as a single dose, in two periods, under fasting conditions.

Secondary: To monitor safety during the Treatment Periods.

Full description

This was a pilot, open-label study to evaluate the PK of enoxaparin following s.c. administrations of 80 mg Clexane, on 2 different occasions, in 14 healthy adult subjects.

The study comprised a Screening Visit and 2 Treatment Periods (1 and 2). Screening (Day -14 to Day -1): Screening assessments were carried out within 14 days before administration of the first dose of Clexane. Eligible subjects were asked to return for Treatment Period 1.

Treatment Periods 1 and 2 (Day 0 to Day 26): Eligible subjects received two doses of s.c. Clexane over 2 Treatment Periods (1 dose/period). Final confirmation of eligibility was made prior to dosing during Treatment Period 1. Confirmation of ongoing eligibility was made prior to dosing during Treatment Period 2.

Each Treatment Period was of 2 days duration, from the afternoon before dosing (Day 0) until 36 hours (h) post-dose (evening of Day 2). During each Treatment Period, subjects resided at the Clinical Unit. Study drug was administered on the morning of Day 1 following an overnight fast. Pharmacokinetic (PK) samples were collected pre-dose and up to 36 h post-dose (x14 samples) for the measurement of enoxaparin. Safety was also evaluated at specified times throughout the study. There were at least 7 days between each dose administration. The Post-Study Follow-Up was conducted on Day 2 of Treatment Period 2 after completion of the 36 h PK blood sampling and vital sign check.
