Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The primary cohort is represented by subjects who have a new indication for the administration of a) new oral anticoagulants (NOAC); b) platelet aggregation inhibitors from the P2Y12 receptor antagonist group (clopidogrel, prasugrel, ticagrelor); c) an HMG-CoA reductase inhibitor (statins); for the purpose of treatment or prophylaxis for at least 3 months; as monotherapy or without restriction with respect to any other concomitant pharmacological therapy.

Who may be able to join

  • age 18 years or older; b) a new indication for the administration of any of the medicinal products of primary interest (NOAC, clopidogrel, prasugrel, ticagrelor, statins) for which at least a 3-month administration is predicted; c) signed informed consent (for repeated evaluations and donation of blood samples for genetic and eventual pharmacokinetic analysis).

Who cannot join

  • the existence of contraindications to the medicines of primary interest.

About this study

The research is planned as a prospective nested case-control study. The plan is to recruit about 1,200 consecutive subjects whose pharmacotherapy involves the drug(s) of interest within 4.5 years. The basic cohort - the subjects with the newly indicated indication for use: NOAC; platelet aggregation inhibitors from the P2Y12 receptor antagonist group; and HMG-CoA reductase inhibitors (statins); as monotherapy or without restriction with respect to any other concomitant pharmacotherapy. The ADRs will be analysed by CR by: age, gender, expectancy, severity, association, type (mechanism of event), and outcome, according to the classification of organ systems as well as association with the phenotype. Criteria for bleeding associated with the use of anticoagulant and antiplatelet therapy have been defined; as well as the myotoxicity and hepatotoxicity associated with statin therapy. Samples will be tested for biochemical, haematological, coagulation standard parameters and pharmacogenetic analyses of relevant genes depending on the used therapy. Pharmacogenetic analysis will be performed to genotype the polymorphisms of relevant pharmacogenes: Biological samples and clinical data will be anonymized plus all records of ADRs and other clinical variables will be protected. Possible drug-drug and drug-drug-gene interactions will be evaluated using the Clinical Decision Support System (CDSS) of Lexicomp, PharmGKB, the Flockhart Table, and other systems including panel consensus methods to determine the likelihood of an ADR being associated with drug interactions, and determine whether drug interactions contributed to the occurrence of ADRs to administered CV pharmacotherapy in subjects with variant pharmacogenes of interest (drug-drug-gene interaction). The overall project objective is to determine which pharmacogenes variants, together with clinical parameters, can be used as predictors of CV drug ADRs and are good candidates for inclusion in the clinical diagnostic panel for pre-emptive PGx testing.

Questions about this trial

What is this clinical trial studying?

An observational study of Pharmacogenetics and Drug-Related Side Effects and Adverse Reactions, run by Clinical Hospital Centre Zagreb at 1 site in Croatia.

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 1 inclusion and 1 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 1 Apr 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 Croatia. 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.

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 Tamara Bozina, PhD (+385 1 45 66 777, tamara.bozina@mef.hr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The overall project objective is to determine which pharmacogenes variants, together with clinical parameters, can be used as predictors of CV drug ADRs (time frame: 4.5 years). 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 NCT05307718, 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 1 Apr 2022; AzTrials last refreshed its copy on 8 Nov 2026.
