Measure: COUNT_OF_PARTICIPANTS
Unit: Participants
Interval / dispersion: Not reported
Time frame: Baseline, Day 1 (Cycle 2, 3, 4, 6, 9, 12, 16), End of study (within 30 days [+ 7 days of last treatment or prior to the start of new anti-cancer treatment], whichever is earlier) (1 cycle=21 days)

What was measured

Serum samples were collected for the determination of ADA using a validated ECL immunoassay. The assay involved screening, confirmation and titration steps. If serum samples contained ADA, they were further analyzed for the specificity of antibodies by a confirmation assay. Confirmed positive (pos) samples were titrated to obtain the titers of antibodies. The number of participants with screening, confirming and negative (neg) conclusive ADA results at Baseline and different timepoints is presented.

Analysis population: Part 1 Population. Only those participants with data available at the specified data points were analyzed (represented by n=X in the category titles).
