结局指标
主要结局
Progression Free Survival (PFS) in Ramucirumab 12mg/kg Arm I4T-MC-JVCZ
时间窗: Randomization to Objective Progressive Disease or Death (Up To 21 Months)
PFS was defined as time from the date of randomization(RD) to date of radiographic documentation of progression(RDP) or the date of death due to any cause, whichever is earlier as defined by RECIST v.1.1. Participants with no tumor progression and no death were censored at date of last adequate radiological assessment (AST) or date of RD(whichever is later).PD is at least a 20% increase in sum of diameters of target lesions,taking as reference the smallest sum on study.In addition to the relative increase of 20%,the sum must also demonstrate an absolute increase of at least 5 mm.The appearance of 1 or more new lesions is also considered progression.Non-Target PD is unequivocal progression of existing nontarget lesions.A participant with incomplete baseline disease had PFS time censored at the enrollment date.A participant not known to have died or have RDP as of the data inclusion cutoff date for the analysis had PFS time censored at date of the last complete RDP-free disease AST.
