Summary
Brief summary (as posted)
The purpose of this study is to investigate the absorption, the metabolic pathways and the excretion of ibrutinib in healthy male adult participants after administration of a single oral dose of 50 mg to 140 mg (5 mg/mL solution) of unlabeled ibrutinib admixed with 14C ibrutinib.
