Genetic Determinants of Dabigatran Plasma Levels and Their Relation to Bleeding
Clinical Trials Monday, March 11th, 2013CIRCULATIONAHA: March 6, 2013
Background—Fixed-dose unmonitored treatment with dabigatran etexilate is effective and has a favorable safety profile in prevention of stroke in atrial fibrillation patients compared to warfarin. We hypothesized that genetic variants could contribute to inter-individual variability in blood concentrations of the active metabolite of dabigatran etexilate, and influence the safety and efficacy of dabigatran.
Methods and Results—We successfully conducted a genome-wide association study in 2,944 RE-LY participants. The CES1 SNP rs2244613 was associated with trough concentrations, and the ABCB1 SNP rs4148738 and CES1 SNP rs8192935 were associated with peak concentrations at genome-wide significance (P<9 x 10-8) with a gene-dose effect.
