What was measured

DOR was measured from the time measurement criteria were first met for CR/PR, as defined in Outcome Measure 1, whichever was recorded first, until the first date of recurrent or Progressive Disease (PD) or death due to any cause in participants with BOR of CR or PR. For participants with metastatic disease, RECIST v1.1 was used to determine BOR. For participants with unresectable locally advanced disease, clinical response criteria were used. RECIST v1.1 Criteria: -PD: At least a 20% increase in the sum of the diameters of target lesions with the sum demonstrating an absolute increase of at least 5 mm (0.5 cm), or the appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. Clinical Response Criteria: -PD: increase of ≥ 25% (World Health Organization (WHO) criteria) in the sum of the products of perpendicular longest dimensions of target lesion(s) and/or the appearance of new lesions.

Analysis population: The FAS included all enrolled participants. Here, 'Overall number of participants analyzed' signifies participants with confirmed CR or PR that are evaluable for this outcome measure. Only Groups 1, 2, 3, 4, and 6 were planned for this outcome measure.
