Bioavailability and Pharmacokinetics Study of Sirukumab in Healthy Male Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to assess the bioavailability (the extent to which a medication becomes available to the body) of subcutaneously (under the skin using a needle) administered sirukumab and to compare the pharmacokinetics of sirukumab administered subcutaneously using a pre-filled syringe fitted with the UltraSafe Passive™ Delivery system (PFS-U) with the SmartJect™ Autoinjector (PFS-AI) in healthy male participants.

Detailed Description
-----------------
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.

Eligibility Criteria
-----------------
Inclusion Criteria: Must have a weight in the range of 50.0 kg to 100.0 kg, inclusive Participant must be healthy on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiogram performed at screening Each participant must sign an informed consent form (ICF) indicating that he understands the purpose of and procedures required for the study and is willing to participate in the study Must be willing and able to adhere to the study visit schedule and other protocol requirements Must agree to abstain from alcohol intake 48 hours before administration of study agent and during the inpatient period of the study Exclusion Criteria: Have any known malignancy or history of malignancy, except for nonmelanoma skin cancer that has been treated with no evidence of recurrence for at least 3 months before Day 1 Have a known history of lymphoproliferative disease, including lymphoma, or signs and symptoms suggestive of possible lymphoproliferative disease, such as lymphadenopathy and/or splenomegaly Have any underlying physical or psychological medical condition that, in the opinion of the investigator, would make it unlikely that the participant will complete the study Have evidence of any chronic medical condition requiring prescription medications (eg, hypertension, elevated cholesterol/triglycerides, asthma, or diabetes) Have a history of or current elevations in triglycerides that required treatment

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Absolute bioavailability of 100 mg sirukumab administered subcutanoeusly | Bioavailability will be evaluated by using the formula: AUC from time zero to infinity with extrapolation of the terminal phase of SC injection divided by AUC from time zero to infinity with extrapolation of the terminal phase of IV infusion of sirukumab and multiplied by 100. | Up to Week 13 | 
| Maximum Observed Serum Concentration (Cmax) of 100 mg sirukumab administered subcutanoeusly | The Serum Concentration (Cmax) is defined as maximum observed analyte concentration. | Up to Week 13 | 
| Area Under the Serum Concentration-Time Curve From Time Zero to 77 days (AUC0-77d) of 100 mg sirukumab administered subcutanoeusly |  | Up to Week 13 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants with adverse events |  | Up to Week 13 | 
| Immunogenicity of sirukumab | Serum levels of antibodies to sirukumab will be used to evaluate potential immunogenicity. | Up to Week 13 |
