Best overall response was defined per RECIST (version 1.1) recorded from randomization until progression or end of study. RECIST (v 1.1) criteria does not require confirmation of response, but an additional, more stringent analysis was also conducted, with designation of CR (or PR) requiring confirmation of response at least 4 weeks following the initial assessment of CR (or PR). Stable disease (SD) required an assessment of SD at least 6 weeks after starting treatment. Subjects with insufficient data for response classification were classified as Not Evaluable for best overall response, and as a non-responder for objective response, in the ITT population. Treatment groups are as indicated for the primary outcome of OS.","dispersionType":"95% Confidence Interval","groups":[{"description":"• MM-398 120 mg/m2 IV on Day 1of a 3 weekly cycle Patients who were homozygous for UGT1A1\\*28 allele received the first cycle of therapy at a reduced dose of 80 mg/m2.
