What was measured

Number of participants with treatment-emergent anti-Pegilodecakin antibodies, defined as participants with at least one postbaseline anti-drug antibody (ADA) titer ≥4-fold increase from baseline (treatment-boosted) or ADA present with titer ≥1:20 if baseline ADA was negative (treatment-induced), analyses were conducted in the TE ADA-evaluable population. A participant is TE ADA evaluable if at least one non-missing ADA result is available at both baseline and postbaseline.

Analysis population: Participants who received at least one dose of study intervention and had evaluable data for this specified outcome.
