Study Endpoints
Primary Endpoints
6-month Progression-Free Survival (PFS) Rate
18 months

6-month PFS rate is the proportion of participants remaining alive and progression free at 6 months. Per RECIST 1.1 criteria: progressive disease (PD) is at least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. PD for the evaluation of non-target lesions is the appearance of one or more new lesions and/or unequivocal progression of non-target lesions.
