PD: At least a 20% increase in the SoD of target lesion, taken as reference the smallest (nadir) SoD since and including baseline. In addition to the relative increase of 20%, the SoD must also demonstrate an absolute increase of at least 5 mm. Unequivocal progression of non-target lesions and appearance of new lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.","dispersionType":"95% Confidence Interval","groups":[{"description":"Participants received mirvetuximab soravtansine IV infusion on Day 1 of every 21-day (Q3W) cycle.
