About this study

Official title: Comparative Study to Evaluate the Relative Bioavailability Between a Fixed-dose Combination Product of 90 mg Ticagrelor/100 mg Acetylsalicylic Acid vs Administration of the Reference Monotherapies in Healthy Subjects.

Study conducted to determine and compare the relative bioavailability of two solid oral formulations (reference versus test) of the non-fixed combination of Ticagrelor 90 mg (Brilinta by AstraZeneca S.A. de C.V.) + Acetylsalicylic Acid 100 mg (ASPIRINA JUNIOR by Bayer de México S.A. de C.V.) administered concomitantly versus the fixed-dose combination of Ticagrelor 90 mg / Acetylsalicylic Acid 100 mg manufactured by Laboratorios Silanes S.A. de C.V.

Questions about this trial

What is this clinical trial studying?

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 16 inclusion and 14 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 2 Mar 2026. 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 Mexico. 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?

Determine Cmax. (time frame: Baseline, 0.16, 0.33, 0.50, 0.75, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50, 4.00, 4.50, 5.00, 6.00, 7.00, 8.00, 10.00, 12.00, 24.0 and 48.0 hours.). The study lists 6 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 NCT07444164.

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 2 Mar 2026.
