About this study

Official title: Correlation Between Bleeding Complication and Treatment Failure on P2Y12 Inhibitors and Its Predictions Based on Cipherome's Pharmacogenomic Technology

The goal of this study is to predict and prevent adverse drug events by investigating the impact of genetic variants, demographics, and environmental factors in subjects status post myocardial infarction and percutaneous coronary insertion who have experienced adverse drug events while on P2Y12 inhibitors.

Read the detailed description

The goal of this study it to validate Cipherome's drug safety score (DSS) in its predictive accuracy for severe adverse drug reactions (ADRs). The DSS is calculated on a scale of 0 to 1, with preliminary studies demonstrating that scores below 0.3 correlated with a higher chance of an ADR and scores above 0.7 correlated with a lower chance of an ADR.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the predictive accuracy of Cipherome's drug safety score (DSS) in correlating with serious ADRs in subjects on P2Y12 inhibitors.

    The primary endpoint is to assess the predictive accuracy of the DSS compared to actual clinical outcomes of treatment failure (major adverse cardiovascular events or MACE) or bleeding (per BARC criteria) in subjects on P2Y12 inhibitors. The DSS is calculated on a scale of 0 to 1, with preliminary studies demonstrating that scores below 0.3 correlated with a higher chance of an ADR and scores above 0.7 correlated with a lower chance of an ADR.

    Measured: Within 24 months of clopidogrel therapy initiation

Secondary outcomes (2)
  1. To assess the predictive accuracy of the DSS in correlating with serious ADRs compared to clinical guidelines (e.g., Clinical Pharmacogenetics Implementation Consortium (CPIC)) in subjects on P2Y12 inhibitors.

    The secondary endpoint is to assess the predictive accuracy of the DSS compared to current evidence-based clinical guidelines, such as CPIC, for serious ADRs (e.g., treatment failure such as MACE) for subjects on P2Y12 inhibitors.

    Measured: Within 24 months of clopidogrel therapy initiation

  2. To assess the predictive accuracy of the DSS in correlating with major bleeding compared to clinical guidelines (CPIC) in subjects on P2Y12 inhibitors.

    The secondary endpoint is to assess the predictive accuracy of the DSS compared to CPIC, for major bleeding per BARC criteria, in subjects on P2Y12 inhibitors.

    Measured: Within 24 months of clopidogrel therapy initiation

Who may be eligible to take part?

The sponsor lists 2 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: finished, as of the sponsor's last update on 16 Feb 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 South Korea. 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?

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?

To assess the predictive accuracy of Cipherome's drug safety score (DSS) in correlating with serious ADRs in subjects on P2Y12 inhibitors. (time frame: Within 24 months of clopidogrel therapy initiation). 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 NCT04580602, which also lists 11 linked publications.

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.
