This is an Open-Label, Single-center, Randomized, Single-Dose, Two-Way Crossover Biosimilarity Study to Determine the Comparative Pharmacodynamics of Enoxaparin Sodium Biosimilar with that from the Reference IMP, Clexane, Following Single-Dose Administration in Healthy Participants.
The data that will be collected include:
* Participant identification data
* Demographic data
* Smoking habits, caffeine use, medication use, alcohol consumption.
* Details of prior participation in any clinical or bioequivalence study.
* Participant medical history, physical examination
* Vital signs, laboratory results, ECG examination, drug abuse \& alcohol test
* Study Drug Information: Details of the administered drug, including time of administration.
* Concomitant Medications
* Blood sampling intervals for Pharmacodynamic (PD) analysis.
* Safety Monitoring: Documentation of any adverse events (AEs) Sample Collection and Sample Processing An intravenous cannula will be inserted before the pre-dose sample and will remain until 24 hours post-dose. Blood samples will be collected through an indwelling cannula placed in a forearm vein using a disposable syringe. If difficulty occurs in blood withdrawing or Participants not feeling comfortable with cannula, cannula will be removed, and remaining blood samples will be collected through fresh vein puncture or by re-cannulation. 5 ml of blood samples will be withdrawn and transferred into sodium citrate collection tubes at each time interval. After collection of blood samples placed in a wet ice container equivalent to the approximate height of the blood in the tube till centrifugation, then after centrifugation, transferred into an ice box containing wet ice and stored at -70°±15° immediately. After the collection of blood samples from all Participants at each time interval, samples will be centrifuged at 3500 RPM for 10 minutes.
All plasma samples will be transferred into pre-labeled (Study code, Participant No., Period, Sampling time point) polypropylene tubes. The polypropylene tubes will be transferred to freezer area in an icebox containing wet ice, and the polypropylene tubes will be stored at -70°±15° freezers. Total Number of Blood Samples: 19 samples in each study period. Volume of each sample: 5 ml. Sampling Hours: pre-dose and 0.5, 1.0, 1.5 (1 h 30 min), 2.0, 2.333 (2 h 20 min), 2.667 (2 h 40 min), 3.0, 3.333 (3 h 20 min), 3.667 (3 h 40 min), 4.0, 4.5 (4 h 30 min), 5.0, 6.0, 8.0, 10.0, 12.0, 16.0, and 24.0 h after dose administration Statistical analysis of primary endpoints for the two periods will include descriptive Statistics, ANOVA, and Confidence Interval (C.I.) of enoxaparin. The equivalence of the products will be concluded if the two -one -sided T-test 90 % confidence interval for the test to reference ratio means is within 80.00 - 125.00 % for each of the ln-transformed data of the following primary endpoints: For Anti-Factor Xa: Anti-Xa Amax, and Anti-Xa AUEC0-t , \& For Anti-Factor IIa: Anti-IIa Amax and Anti IIa AUE0-t and finally if there were no safety concerns and both products were well tolerated by the study Participants.
