Objective To evaluate the bioequivalence of test and reference preparation of Ibrutinib Capsules under fasting and fed condition. Methods A single center, randomized, open label, two-formulation, two-sequence, four-period and completely repeated crossover trial under fasting and fed condition. 40 Cases and 32 healthy subjects were enrolled under fasting and fed condition, respectively, and 140 mg test and reference preparation of Ibrutinib Capsules were taken orally every cycle. The plasma concentration of ibrutinib was analyzed by LC-MS/MS method. Pharmacokinetic parameters were calculated by Phoenix WinNonlin 8.3, and other statistical analysis was performed by SAS 9.4. Results The pharmacokinetic parameters Cmax, AUC0-t, and AUC0-∞ of healthy subjects under fasting and fed condition all fell within the range of [80.00%, 125.00%] after logarithmic transformation. Conclusion The test or reference product of Ibrutinib Capsules is bioequivalent in healthy volunteers under fasting and fed condition after a single oral administration.
