Association Between Genetic Variant Scores and DOACs (DARES2)

August 14, 2023 updated by: Cipherome, Inc.

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

The study's objective is to evaluate the predictive accuracy of Cipherome's algorithm in predicting and preventing serious adverse drug reactions (ADRs) experienced by patients while on direct oral anti-coagulants (DOACs).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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
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.
Within 1 year of DOAC therapy initiation

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
To evaluate the predictive accuracy of the DSS in correlating with serious ADRs compared to clinical tools (e.g., HAS BLED criteria).
Time Frame: Within 1 year of DOAC therapy initiation
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.
Within 1 year of DOAC therapy initiation
To evaluate the predictive accuracy of the DSS in correlating with treatment failures while on Direct Oral Anti-coagulants (DOACs)
Time Frame: Within 1 year of DOAC therapy initiation
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.
Within 1 year of DOAC therapy initiation

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
To discover novel pharmacogenetic variants associated with Direct Oral Anti-coagulants (DOACs)
Time Frame: Within 1 year of DOAC therapy initiation
Novel variants will be assessed using whole genome sequencing to evaluate the genetic pathways in individuals with serious ADRs and treatment failures. Through our analyses we intend to identify novel genetic variants in subjects with serious ADRs or treatment failure while on P2Y12 inhibitors.
