Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs) From the first IMP administration to the last IMP administration + 14 weeks (i.e., up to 36 weeks) An adverse event (AE) was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily have to have a causal relationship with the treatment. Serious adverse events (SAEs) was defined as any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. TEAEs were defined as AEs that developed, worsened or became serious during the treatment-emergent (TE) period (time from the first investigational medicinal product \[IMP\] administration to the last IMP administration + 14 weeks).
Number of Participants With Treatment-emergent and Treatment Boosted Antidrug Antibodies (ADA) From the first IMP administration to the last IMP administration + 14 weeks (i.e., up to 36 weeks) ADA response was categorized as: Treatment emergent and Treatment-boosted. Treatment emergent ADAs were defined as a participant with no positive assay response at baseline but with a positive assay response during the entire TEAE period. Treatment boosted ADAs: defined as participants with a positive ADA assay response at baseline and with at least a 4-fold increase in titer compared to baseline during the TE period (time from the first IMP administration to the last IMP administration + 14 weeks). Titer values were defined as low titer (\< 1,000); moderate (1,000 \<= titer \<= 10,000) and high titer (\> 10,000).
