About this study

Official title: Open-label Randomized Crossover Two Period Single Dose Bioequivalence Study of Two Formulations Aceclofenac Tablets 100 mg (Pharmtechnology LLC, Republic of Belarus) and Airtal® Tablets 100 mg (Gedeon Richter- RUS", Russia / Gedeon Richter, Hungary; MA Holder: Almiral S.A., Spain) in Healthy Volunteers Under Fasting Conditions

This is an open-label, randomized, two period, single-center, crossover, comparative study, where each participant will be randomly assigned to the reference (Airtal ®, 100 mg film-coated tablets) or the test (Aceclofenac, 100 mg film-coated tablets) formulation in each period of study (sequences Test-Reference (TR) or Reference-Test (RT)), in order to evaluate if both formulations are bioequivalent.

Read the detailed description

This is an open-labeled, randomized, two period, crossover, a single-center, comparative, single-dose study, in which 36 healthy adult subjects will receive one of the study treatments during each study period.

The objective of this study is to determine the bioequivalence of two different formulations of aceclofenac after a single oral dose administration under fasting conditions.

Subject eligibility for this study will be determined at the screening visit and eligible subjects will be admitted to the clinical research unit at least 12 hours prior to drug administration for each study period.

Hospitalization in the first period of the study will last no more than 37 hours, after which, in the absence of indications for an extension of hospitalization, each subject will be released home; after that, the first period of the study will be completed.

The procedures of the second study period will be identical to the first period.

After completing all the procedures of the second study period, each subject will undergo a final examination, after which, in case of the absence of adverse events and indications for prolonging hospitalization, the study for the subjects will be considered completed.

The total duration of the study for the subject will be no more than 22 days.

Eligible subjects will be randomized to one of two treatment sequences. There will be two sequences in the study: TR and RT, where T = the test product, R = the reference product.

For each study period, subjects will receive a single 100 mg oral dose of aceclofenac (the test or the reference formulation). Study participants will be aware they will receive different formulations of the same drug, without being informed which product (Test or Reference) is being administered. For each subject, all scheduled postdose activities and assessments will be performed relative to the time of study drug administration.

Fasting will continue for at least 4 hours following drug administration, after which a standardized lunch will be served. Next meals will be provided for subjects in 6 hours, 9 hours and 12 hours after drug administration.

Water will be provided as needed until 1 hour predose. Water will be allowed beginning 2 hours after the administration of the drug.

A total of 20 blood samples will be collected (one tube of 6 mL each) in each study period for pharmacokinetic (PK) assessments. The first blood sample will be collected prior to drug administration while the others will be collected up to 24 hours after drug administration.

Aceclofenac plasma concentrations will be measured according to a validated bioanalytical method.

Statistical analysis of all PK parameters will be based on an ANOVA model. Two-sided 90% confidence interval of the ratio of geometric LSmeans obtained from the ln-transformed PK parameters will be calculated.

Statistical inference of aceclofenac will be based on a bioequivalence approach using the following standards: the ratio of geometric LSmeans with corresponding 90% confidence interval calculated from the exponential of the difference between the Test and the Reference for the ln-transformed parameters Cmax and AUC0-t should all be within the 80.00 to 125.00% bioequivalence range.

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 15 inclusion and 35 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: finished, as of the sponsor's last update on 28 Jun 2023. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Cmax of aceclofenac in plasma after administration of the test and the reference products. (time frame: Time points 0.00 (prior to each drug administration) and 0.15, 0.30, 0.45, 1.00, 1.15, 1.30, 1.45, 2.00, 2.20, 2.40, 3.00, 3.30, 4.00, 5.00, 6.00, 8.00, 10.00, 12.00, 24.00 hours after each drug administration.). 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 28 Jun 2023.
