About this study
Official title: Single Dose Crossover Comparative Bioavailability Study of Febuxostat 120 mg Film-Coated Tablets in Healthy Adult Subjects / Fasting State
This study is designed in accordance with the European Medicines Agency (EMA) regulatory guidelines, with the aim of characterizing the bioavailability of febuxostat in the two formulations in healthy adult subjects. Within the clinical portion of the study each subject will receive a single oral dose of the test and the reference formulation in compliance with the generated randomization code. The primary study endpoints are the pharmacokinetic (PK) parameters Cmax and AUC0-T of febuxostat.
Read the detailed description
This is a single center, randomized, 2-treatment, 2-period, 2-sequence, crossover, single dose study design, in which 50 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 febuxostat after a single oral dose administration under fasting conditions.
The intra-subject variation following a single dose of febuxostat appears to be up to 34% for Cmax and up to 12% for AUC0-T. Statistically, given that the expected Test to Reference ratio of geometric LSmeans should fall within 95 and 105%, it is estimated that the lowest number of subjects to meet the 80 to 125% bioequivalence range with a statistical a priori power of at least 80% is about 46. Therefore, the inclusion of 50 subjects should be sufficient to account for the possibility of drop-outs, variations around the estimated intra-subject CV and to conclude in favor of the hypothesis of bioequivalence with sufficient statistical power.
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 10 hours prior to drug administration for each study period.
A subject who withdraws or is withdrawn during the pretrial evaluations but before receiving the investigational product (IP) will not be considered as a drop-out and will not be included in the final database. Standbys should be recruited and available to replace any subject who withdraws prior to the first drug administration. On-study drop-outs will not be replaced.
Altasciences will generate the randomization code with a computer program according to the study design, the number of subjects and the sequence of treatment administration. The random allocation of each sequence of treatment administration to each subject will be done in such a way that the study is balanced. Once generated, the randomization code will be final and will not be modified. Eligible subjects will be randomized to one of two treatment sequences. There will be two sequences in the study: AB and BA, where A = the test product, B = the reference product (see detailed description of A and B items in Section "Arms and Interventions").
For each study period, subjects will receive a single 120 mg oral dose of febuxostat (the test or the reference formulation), with approximately 240 mL of water at ambient temperature, following a 10-hour overnight fast. The tablet must be swallowed whole and must not be chewed or broken. 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. The date and time of each dose will be recorded. 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. A supper and a light snack will be served at appropriate times thereafter, but not before 9 hours after dosing. Water will be provided as needed until 1 hour predose. Water will be allowed beginning 1 hour after the administration of the drug.
In each study period, 21 blood samples will be collected for PK assessments. The first blood sample will be collected prior to drug administration while the others will be collected up to 36 hours after drug administration. Febuxostat plasma concentrations will be measured by a validated bioanalytical method.
Subjects are to be discharged from the clinic after the 36-hour postdose PK sample collection, and following medical approval. However, they may be advised to stay at the clinical site for safety reasons, if judged necessary by the physician in charge.
The expected terminal elimination half-life observed after a single oral 120 mg dose of febuxostat film-coated tablets under fasting conditions is 5.1 hours. To avoid any carry-over effect, a wash-out of 7 calendar days is planned between drug administrations.
The decision of which subjects will be included in the PK analysis is to be documented by the pharmacokineticist (or delegate) and approved by the sponsor before the start of the sample analysis by the bioanalytical facility. Subjects who are expected to provide evaluable PK data for both the Test and Reference products (based on viable PK samples) will be included in the pharmacokinetic analysis. Concentration data of the remaining subjects will be presented separately. Subjects who do not complete the sampling schedule of one or more study periods may be included in the PK and statistical analysis and bioequivalence determination for only the PK parameters that are judged not to be affected by the missing sample(s).
Statistical analysis of Tmax will be based on a non-parametric approach. Statistical analysis of all other pharmacokinetic parameters will be based on an analysis of variance (ANOVA) model. Two-sided 90% confidence interval of the ratio of geometric least-squares means (LSmeans) obtained from the ln-transformed pharmacokinetic parameters will be calculated.
Statistical inference of febuxostat 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 safety population will include all subjects who received at least one dose of one of the IPs. Safety assessments will include clinical laboratory tests, and adverse event (AE) monitoring. Additional safety measurements may be performed at the discretion of the investigator for reasons related to subject safety. The physician in charge will be present at the clinical site for at least the first 4 hours following each drug administration and will remain available at all times throughout the study.
Total study duration: up to 35 days (including screening).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is designed in accordance with the European Medicines Agency (EMA) regulatory guidelines, with the aim of characterizing the bioavailability of febuxostat in the two formulations in healthy adult subjects. Within the clinical portion of the study each subject will receive a single oral dose of the test and the reference formulation in compliance with the generated randomization code. The primary study endpoints are the pharmacokinetic (PK) parameters Cmax and AUC0-T of febuxostat.
Detailed description
This is a single center, randomized, 2-treatment, 2-period, 2-sequence, crossover, single dose study design, in which 50 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 febuxostat after a single oral dose administration under fasting conditions.
The intra-subject variation following a single dose of febuxostat appears to be up to 34% for Cmax and up to 12% for AUC0-T.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Febuxostat and Adenuric in people with Bioequivalence, run by Pharmtechnology LLC at 1 site in Canada.
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 19 inclusion and 19 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 8 Jul 2019. 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 Canada. 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 febuxostat in plasma after administration of the test and the reference products (time frame: Time points 0.00 (prior to each drug administration) and 0.25, 0.50, 0.67, 0.83, 1.00, 1.25, 1.50, 2.00, 2.50, 3.00, 4.00, 5.00, 6.00, 8.00, 10.00, 12.00, 15.00, 18.00, 24.00, 36.00 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 8 Jul 2019.
