Current Primary Outcome Measures (submitted: August 24, 2012)

• Maximum concentration (Cmax) of ibrutinib [ Time Frame: Day 1 (Predose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours) ]
  Pharmacokinetic parameter Cmax of ibrutinib will be determined.
• Time to reach the maximum concentration (tmax) of ibrutinib [ Time Frame: Predose, Day 1 (0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours) ]
  Pharmacokinetic parameter tmax of ibrutinib will be determined.
• Area under the concentration-time curve (AUC) of ibrutinib [ Time Frame: Predose, Day 1 (0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours) ]
  Pharmacokinetic parameter AUC of ibrutinib will be determined.
• Amount excreted into the urine (Ae) of ibrutinib [ Time Frame: Day -1, Day 1 over intervals 0-2, 2-4, 4-8, 8-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168 hours, Days 9-15 ]
  Pharmacokinetic parameter Ae of ibrutinib will be determined by multiplying the urinary volume with the urinary concentration.

Descriptive Information

• Brief Title: A Study to Determine the Absorption, Metabolism, and Routes of Excretion of (14C) Radiolabeled Ibrutinib in Healthy Male Participants
• Official Title: An Open-Label Phase 1 Study to Determine the Pharmacokinetics, Metabolism, and Routes of Excretion of (14C) Radiolabeled PCI-32765 in Healthy Male Subjects
• Brief Summary: 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.
• Detailed Description: This is an open-label (all people know the identity of the intervention), single-center, single-dose study in healthy male participants. Six men will be enrolled to allow a minimum of 4 participants to complete the study. All participants will receive a single oral solution dose of 50 to 140 mg ibrutinib containing 1480 kBq (40 µCi) of 14C labeled ibrutinib, constituting a total radiation burden of approximately 0.916 mSv (ICRP risk category IIa). The duration of the study is approximately 73 days including screening period of 28 days, treatment period of 15 days, and follow-up period of 30 days. Safety will include adverse events, laboratory safety, 12 lead electrocardiogram, physical examination, and vital signs.
