Bioavailability and Pharmacokinetics Study of Sirukumab in Healthy Male Participants

This is a randomized (the study medication is assigned by chance), open-label (all people know the identity of the intervention), parallel-group (each group of participants will be treated at the same time), multicenter; single-dose study. Approximately 138 participants will be randomly allocated in a 3:3:3:7:7 ratio to 1 of the 5 treatment groups as follows: Group 1 (a single intravenous infusion of 100 mg sirukumab), Group 2 (a single subcutaneous \[SC\] injection of 50 mg sirukumab with PFS-U), Group 3 (a single SC injection of 50 mg sirukumab with PFS-AI, Group 4 (a single SC injection of 100 mg sirukumab with PFS-U), and Group 5 (a single SC injection of 100 mg sirukumab with PFS-AI). Randomization will be stratified by body weight (50.0 kg to \<70.0 kg, 70.0 kg to \<85.0 kg, 85.0 kg to 100.0 kg). Participants will be hospitalized in the study unit for administration of study drug and will be discharged after completion of all scheduled assessments on Day 5. Participants will be required to return to the study unit for outpatient visits on Days 6 and 7, followed by weekly/biweekly outpatient visits, and then a safety follow-up for a total of 13 weeks after study drug administration. Safety evaluations will include assessment of adverse events, physical examination, vital signs, injection site and infusion reactions, electrocardiogram, and clinical laboratory tests. The maximum study duration for each participant will be 120 days.
