About this study

Official title: A PHASE IV, OPEN LABEL, RANDOMIZED, TWO TREATMENT, TWO PERIOD, TWO SEQUENCE, CROSSOVER BIOEQUIVALENCE STUDY TO COMPARE AN ORAL FORMULATION OF TRAMADOL HYDROCHLORIDE 37.5 MG/PARACETAMOL 325 MG TABLETS (TEST PRODUCT OF PFIZER) VERSUS ULTRACET(REGISTERED) (TRAMADOL HYDROCHLORIDE/PARACETAMOL 37.5 MG/325 MG OF JANSSEN CILAG FARMACÊUTICA LTDA, REFERENCE PRODUCT OF BRAZIL) IN HEALTHY ADULT RESEARCH SUBJECTS UNDER FASTING CONDITIONS

The sponsor, Pfizer has developed a formulation of tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg (test drug) as a generic alternative to the reference listed product Ultracet®. In order to meet the requirements for registration as a generic drug, this study is being conducted to demonstrate the bioequivalence between the formulation of tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg provided by Pfizer and the reference drug tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg, available in the pharmaceutical market in Brazil (Ultracet®, Janssen Cilag Farmacêutica Ltda).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ultracet Tablets and Tramadol hydrochloride 37.5 mg/Paracetamol 325 mg tablets - tablet (Pfizer) in people with Healthy, run by Pfizer at 1 site in Brazil.

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 8 inclusion and 21 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 17 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 Brazil. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Area under the tramadol and paracetamol plasma concentration-time curve from time zero to last time point (AUClast) (time frame: Predose (0 hour), at 0.08, 0.16, 0.25, 0.33, 0.41, 0.50, 0.66, 0.83, 1.0, 1.25, 1.5, 1.75, 2.0, 2.5, 3.0, 4.0, 6.0, 8.0, 12, 24 and 36 hours post dose). 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 17 Jul 2019.
