About this study

Official title: Study Name: (SPRING) Study of Pharmacodynamics and Relative Bioavailability of an Invented National Generic Enoxaparin

An Open-Label, Single-center, Randomized, Single-Dose, Two-Way Crossover Biosimilarity Study to Determine the Comparative Pharmacodynamics of Enoxaparin Sodium Biosimilar 40mg/0.4ml with that from the Reference IMP, Clexane® (40 mg/0.4ml), Following Single-Dose Administration in Healthy Participants. Test: Enoxaparin Sodium (Enoxaparin Sodium 40mg/0.4ml) manufactured by EIPICO, Egypt. Reference: Clexane (Enoxaparin Sodium 40mg/0.4ml) manufactured by Sanofi Aventis, Egypt. Primary objective:

Secondary objective:

To investigate the safety and tolerability of the formulations. This study is a randomized single-dose, two-way, two-period, two-sequence, crossover biosimilarity study with a washout period of one week after each dosing.A minimum of 21 healthy adult male and female participants from Egyptian population will be enrolled in this study, along with 5 additional participants to account for potential dropouts or withdrawal. 26 Participants plus 1-4 alternates will be admitted to the study. An alternate participant will be dosed by the same sequence as the withdrawn participant only if any participant of the first 26 Participants withdraws before the first study drug administration. Withdrawals after study drug administration will not be replaced. All participants will be healthy adults aged (21-55) years, with a BMI within the accepted range of 18.5-30 kg/m², and will meet the study's selection criteria.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Endpoints

    Anti-Xa max: The maximum observed anti-Factor Xa activity in plasma following a single dose

    Measured: 4 months

  2. Primary outcome 2

    AUEC0-t (Area under the Effect Curve from time zero to last quantifiable time): The area under the anti-Xa effect-time curve from time zero (dosing) to the last measurable time point (T).

    Measured: 4 months

Secondary outcomes (4)
  1. Secondary outcome

    AUEC0-inf (Area under the Effect Curve extrapolated to infinity): The total area under the anti-Xa effect-time curve, extrapolated to infinity

    Measured: 3 months

  2. Secondary outcome 2

    Tmax (Time to maximum effect): The time post-dose at which the maximum anti-Xa activity occurs.

    Measured: 3 months

  3. Secondary outcome 3

    T½ (Half-life of anti-Xa activity): The time required for the anti-Xa activity to decline by 50% during the terminal phase.

    Measured: 3 months

  4. Secondary outcome 4

    λz (lambda z): The elimination rate constant of the anti-Xa activity. It is a pharmacokinetic parameter describing the rate at which the anti-Xa activity decreases in the plasma over time. It represents the slope of the terminal phase on a concentration-vs-time curve (logarithmic scale).

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Enoxaparin 40 Mg/0.4 mL Injectable Solution in people with Healthy Participants Study and The Focus of the Study is to Determine the Comparative Pharmacodynamic of Enoxaparin Sodium With That of Clexane in Healthy Human Participants, run by Egyptian International Pharmaceutical Industries Co.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 8 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Endpoints (time frame: 4 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2026.
