Outcome Measures
Primary Outcomes (2)
Progression Free Survival (PFS)
Progression-free survival estimated using Kaplan-Meier methods is defined as the time from the date of informed consent to the earlier of death or disease progression. Patients alive without disease progression are censored at the date of last disease evaluation. Progressive disease (PD) based on RECIST 1.1 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. Equivocal progression of non-target lesions also qualifies as PD.
2 years
Objective Response Rate (ORR)
The overall response rate is defined as the percentage of patients with a best overall response of CR or PR relative to the appropriate analysis set
