About this study

Official title: Double-blind, Randomized Comparative Cross-sectional Study of Pharmacodynamics and Pharmacokinetics of Drugs GP40141, Powder for Solution for Subcutaneous Administration, 250 µg (GEROPHARM LLC, Russia) and Enplate®, Powder for Solution for Subcutaneous Administration, 250 µg (Amgen Europe B.V. ., Netherlands) in Healthy Volunteers With a Single Subcutaneous Injection

Bioequivalence Study of GP40141 (GEROPHARM) versus Enplate®. The study of comparative pharmacodynamics, pharmacokinetics and safety of drugs containing romiplostim in healthy volunteers after a single subcutaneous injection.

Read the detailed description

The goal of this study, conducted as a double-blind, randomized, cross-over study of comparative pharmacodynamics and pharmacokinetics, is to compare pharmacodynamics, pharmacokinetics, and safety of drugs containing romiplostim - GP40141 and Nplate® in healthy volunteers after a single subcutaneous injection.

research objectives is:

  1. Evaluate pharmacodynamic and pharmacokinetic parameters of active ingredients of preparations GP40141 and Enplate®.
  2. Conduct a comparative analysis of pharmacodynamic and pharmacokinetic parameters of active substances drugs GP40141 and Enplate®.
  3. Conduct a comparative analysis of data on adverse events (AE) and evaluate immunogenicity after a single subcutaneous administration of GP40141 versus Enplate®. A conclusion about the biosimilarity of drugs will be made by assessing 90% confidence intervals for the ratios of the geometric mean values of the primary pharmacodynamic parameters.

The safety of the compared drugs will be assessed by emergence and development of AE.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GP40141 and Nplate in people with Pharmacodynamics and Pharmacokinetics, run by Geropharm at 1 site in Russia.

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 4 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: status not confirmed, as of the sponsor's last update on 15 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact Igor Mr Makarenko, PhD (+78124935501 ext. 470, Igor.Makarenko@geropharm.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

AUCplt (time frame: -45, -30, -15 min and days 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 32 post injection). 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?

On the ClinicalTrials.gov record for NCT05652595, which also lists 1 linked publication.

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 15 Dec 2022.
