What was measured

Blood samples were collected for immunogenicity analysis. Anti-drug antibody positive (ADA+) participants were those with a positive result on the first test and also a positive result on the confirmatory test. Anti-drug antibody negative (ADA-) participants had a negative result on the first test.

Analysis population: Immunogenicity was assessed in the Safety Analysis Set.
