First Dose of Study Drug to PD (Up to 2.61 years)

What was measured

Time from first dose of study drug to the earliest documented evidence of PD. Per RECIST v1.1, PD defined as at least a 20% increase in the sum of the disease measurements for measurable lesions, taking as reference the smallest disease measurement recorded since the start of treatment, or the appearance of one or more new lesions. mRECIST used for pleural mesothelioma defines PD as an increase of at least 20% in the sum of the diameters of viable target lesions.

Analysis population: mITT participants that were evaluable for this outcome measure.
