- Part 1: From pre-infusion on day 1 up to end of study treatment (maximum treatment exposure for Part 1 was 414 days)
What was measured
A participant was ADA (or NAb) positive if: (1) baseline titer was missing or negative and participants had \>1 post-treatment positive titer (treatment-induced), or (2) positive titer at baseline and had a \> \[4-fold dilution increase\] in titer from baseline in \>1 post-treatment sample (treatment-boosted).
Analysis population: Immunogenicity analysis population included all treated participants with at least one ADA sample (pre-dose or post-treatment) analyzed. Here, "Number of Participants Analyzed" signifies number of participants who were ADA or NAb evaluable.
