bioavailability study of enoxaparin sodium chemi and clexane s.c.

Conditions: Enoxaparin Sodium is Administered to Healthy Volunteers

Summary: * the primary objective of the trial is to assess the single-dose relative bioavailability of chemi enoxaparin (80 mg/0.8 ml) and clexane® (80 mg/0.8 ml) administered by subcutaneous (s.c.) injection, under fasting conditions in healthy volunteers. * the secondary objective of the trial is to assess safety and tolerability of chemi enoxaparin (80 mg/0.8 ml) and clexane® (80 mg/0.8 ml) administered by s.c. injection, under fasting conditions in healthy volunteers.

this is an open-label, randomised, single-dose, 2-way crossover study to determine the comparative bioavailability of enoxaparin sodium from the chemi enoxaparin s.c. (80 mg/0.8ml) with that from the reference imp, clexane® s.c. (80 mg/0.8ml), following single dose administration in healthy male and female subjects. each subject received each treatment over two separate treatment periods under fasting conditions. each dosing day for male subjects will be separated by a washout period of at least 7 days. the study comprised a pre-study screen (within 14 days of the first dose), followed by 2 treatment periods (1 and 2). during each treatment period, subjects will reside at simbec from the evening before dosing (day 1), until at least 36 h post dose (evening of day 2). on admission (day -1), subjects will provide a urine sample for a drugs of abuse screen; this sample will also be tested to confirm a negative pregnancy result in female volunteers. a single dose of the randomised treatment will be given on the morning of day 1 following an overnight fast and blood pk/pd samples collected from pre-dose up to 36 h post dose (14 samples). safety will also be evaluated at specified times throughout the study. the post study visit will be conducted on day 2 (36 h post-dose) of treatment period 2.
