Primary Outcome Measures

Name	Time	Method
Percentage of Participants Developing Anti-Drug Antibodies (ADAs) and Neutralizing Antibodies (NAbs)	At Baseline and Weeks 8, 16, 24, 32, 40, 48, 56, 64, 72 and 76.	Samples were analyzed using the semi-quantitative electrochemiluminescent (ECL) immunoassay method, a validated analytical method in compliance with sponsor's standard operating procedures. ADA positive is defined as ADA titer greater than or equal to (\>=) 4.32. Any positive ADA sample was further tested for NAbs.
Number of Participants With On-Treatment Treatment-Emergent Adverse Events (AEs), Serious Adverse Events (SAEs), and Discontinuations Due to AEs	Baseline up to Week 48	An AE was any untoward medical occurrence without regard to causality in a participant who received study drug. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of death); persistent or significant disability/incapacity; congenital anomaly. Lack of efficacy was reported as an AE when it was associated with a SAE. An AE was considered treatment emergent if it started for the first time in a participant on or after the first day of active treatment, or the event started before the first day of active treatment but increased in severity during active treatment. AEs included both SAEs and non-serious AEs.
