Clexane is Administered to Healthy Volunteers
Conditions
Keywords
enoxaparin sodium
Brief summary
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.
Detailed 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.

This is a single arm study and not a parallel group study. This means that the participants are 14 in total. The 14 eligible subjects received 1 dose of s.c. Clexane in Treatment Period 1 and 1 dose of S.C. Clexane in Treatment Period 2 (1 dose/period). Each Treatment Period was of 2 days duration.

|---|---|
| Clexane - PK Population Eligible subjects received two doses of s.c. Clexane over 2 Treatment Periods (1 dose/period).
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). Study drug was administered on the morning of Day 1 following an overnight fast.
There were at least 7 days between each dose administration. In period 1, one dose of Clexane was administered s.c. into the left or right side of the abdomen (alternating sides with Treatment Period). This dose contained 80 mg enoxaparin sodium (equivalent to 8,000 international units (IU) anti-factor Xa (anti FXa activity) in 0.8 mL of water for injection.
In period 2 one dose of Clexane was administered s.c. into the left or right side of the abdomen (alternating sides with Treatment Period). This dose contained 80 mg enoxaparin sodium (equivalent to 8,000 international units (IU) anti-factor Xa (anti FXa activity) in 0.8 mL of water for injection. | 14 |

Outcome results
Anti-FIIA AUC0-inf
Enoxaparin exerts its anti-coagulant effect primarily via interaction with anti-thrombin III (ATIII), thereby enhancing the inhibitory effect of ATIII on activated factor Xa (FXa) and thrombin/factor IIa (FIIa). Inhibition of FXa activity prevents conversion of prothrombin/factor II (FII) to FIIa and inhibition of FIIa activity (direct/indirect) prevents conversion of fibrinogen to fibrin and therefore clot formation. As enoxaparin cannot be measured directly in blood, the PK of enoxaparin have been studied on the basis of its effect on clotting mechanisms, particularly the inhibition of FXa (anti-FXa) and FIIa (anti-FIIa) activity. AUC0-inf is the AUC extrapolated to infinity from dosing time, based on the last observed value.
Time frame: Pre-dose, and at the following times post-dose: 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24 and 36 h in Period 1 and Period 2.
Population: PK Population: All subjects who received study medication in both Treatment Periods, had sufficient plasma activity/concentration-time profiles and who did not violate the protocol in such a way that may have invalidated or biased the results (major protocol violators) were included in the PK analysis.
