Apixaban is metabolized by cytochrome P450 (CYP) 3A4 in the liver and intestine, undergoes direct intestinal excretion, and is a substrate to permeability glycoprotein (P-gp) and breast cancer resistance protein (BCRP) transporters. We examined the drug interactions between cyclosporine and tacrolimus (combined inhibitors of CYP3A4, P-gp and, BCRP) with apixaban in 12 healthy adult male volunteers. Apixaban 10 mg was administered orally alone, in combination with 100 mg cyclosporine or 5 mg tacrolimus. Co-administration with cyclosporine resulted in increase in apixaban maximum plasma concentration (C ) and area under the plasma concentration-time curve from time zero to the last quantifiable concentration [AUC ] with associated geometric mean ratios (GMR) and 90% confidence intervals (CI) of 143% (112, 183) and 120% (97, 148). Co-administration with tacrolimus resulted in reduction in apixaban C and AUC with associated GMRs (90% CI) of 87% (69, 112) and 78% (63, 97). The observed changes in apixaban exposure margins with cyclosporine or tacrolimus are within the range of the historical clinical development program, therefore apixaban dose adjustments are not warranted.
