What was measured

ADA samples scoring equal to or above the cut-point (titer of 75) were defined as ADA positive. Percentages were rounded off to the nearest decimal.

Analysis population: The Immunogenicity-evaluable Analysis Set included participants from the SAS with a baseline assessment and at least 1 postbaseline immunogenicity assessment. Overall number of participants analyzed is the number of participants with data available for analyses.
