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

What is being measured

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

  1. To determine the predictive accuracy of Cipherome's Drug Safety Score (DSS) in correlating with serious Adverse Drug Reactions associated with Direct Oral Anti-coagulants (DOACs) (rivaroxaban, apixaban, dabigatran, and edoxaban).

    The primary endpoint is to determine the accuracy of the DSS in predicting clinical outcomes of major bleeding per International Society of Thrombosis and Haemostatis (ISTH) criteria in subjects on Direct Oral Anti-coagulants (DOACs). The DSS is calculated on a scale of 0 to 1, with scores below 0.3 correlated with a higher risk of ADRs and scores above 0.7 correlated with a lower risk of ADRs. We will determine the DSS of all subjects who experienced major bleeding and compare it to the DSS of control subjects who did not experience bleeding.

    Measured: Within 1 year of DOAC therapy initiation

Secondary outcomes (2)
  1. To evaluate the predictive accuracy of the DSS in correlating with serious ADRs compared to clinical tools (e.g., HAS BLED criteria).

    The secondary endpoint is to determine the accuracy of the DSS predicting clinical outcomes compared to clinical tools such as the HAS-BLED scoring system. A subject with a HAS-BLED score of > 4 points will be considered moderate-high risk of bleeding and a HAS-BLED score of 4 or less will be considered low risk. A DSS is calculated on a scale of 0 to 1, with scores below 0.3 correlated with a higher risk of ADRs and scores above 0.7 correlated with a lower risk of ADRs. Both DSS (low and high risk subjects) and HAS-BLED scores (low and high risk subjects) will be compared to actual clinical outcomes to assess the predictive accuracy of each scoring system.

    Measured: Within 1 year of DOAC therapy initiation

  2. To evaluate the predictive accuracy of the DSS in correlating with treatment failures while on Direct Oral Anti-coagulants (DOACs)

    The secondary endpoint is to determine the accuracy of the DSS in predicting treatment failures (e.g., recurrent MI, systemic embolism, or ischemic stroke) as compared to clinical outcomes while on DOACs. The DSS is calculated on a scale of 0 to 1, with preliminary studies demonstrating that scores below 0.3 correlated with a higher risk of ADRs and scores above 0.7 correlated with a lower risk of ADRs.

    Measured: Within 1 year of DOAC therapy initiation

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: finished, as of the sponsor's last update on 16 Aug 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 determine the predictive accuracy of Cipherome's Drug Safety Score (DSS) in correlating with serious Adverse Drug Reactions associated with Direct Oral Anti-coagulants (DOACs) (rivaroxaban, apixaban, dabigatran, and edoxaban). (time frame: Within 1 year of DOAC 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 NCT04597593, which also lists 15 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.
