The purpose of this study is to investigate the absorption, metabolic pathways and excretion of JNJ-39823277 in healthy male adults after administration of a single oral dose of a 25 mg (0.5 mg/mL solution) of 14C-JNJ-39823277.
This is an open-label (all people know the identity of the intervention) and single-arm (group) study. The study consists of 3 phases including, the screening phase (within 3 weeks prior to the start of study medication), treatment phase (8 to 15 days), and the follow-up phase (up to 6 days after the discharge from the hospital). Approximately 6 participants will be receiving the 14C-JNJ-39823277 in the study. Safety will be evaluated by the assessment of adverse events, vital signs, physical examination, 12-lead electrocardiogram, and clinical laboratory tests which will be monitored throughout the study. The total duration of study will be up to approximately 6 weeks.

Maximum observed plasma concentration (Cmax) of 14C-JNJ-39823277 in plasma
Time frame: Predose; 15 and 30 minutes, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, 24, 36, 48, 72, 120, and 168 hours post-dose
Time of observed maximum plasma concentration (Tmax) of 14C-JNJ-39823277
The Tmax is defined as actual sampling time to reach maximum observed analyte concentration.
Time frame: Predose; 15 and 30 minutes, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, 24, 36, 48, 72, 120, and 168 hours post-dose
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of 14C-JNJ-39823277
The AUClast is area under the plasma concentration-time curve from time zero to the last quantifiable concentration.
Time frame: Predose; 15 and 30 minutes, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, 24, 36, 48, 72, 120, and 168 hours post-dose
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of 14C-JNJ-39823277
The AUC(0-infinity) is area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of Area under Curve (AUC) last and C(last)/lambda(z), in which C(last) is the last observed quantifiable concentration.
Time frame: Predose; 15 and 30 minutes, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, 24, 36, 48, 72, 120, and 168 hours post-dose
Elimination Half-Life Period (T1/2) of 14C-JNJ-39823277
T1/2 is the time measured for the plasma concentration to decrease by one-half of its original concentration. It is associated with the terminal rate-constant (lambda\[z\]) of the semi logarithmic drug concentration-time curve, and is calculated as 0.693/lambda(z).
Time frame: Predose; 15 and 30 minutes, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 18, 24, 36, 48, 72, 120, and 168 hours post-dose
