Progression (i.e., PD) was defined as at least a 20% increase in the sum of diameters of target lesions (TLs) and an absolute increase of ≥5mm, taking as reference the smallest sum of diameters since treatment started including the baseline sum of diameters, or a measurable increase in a non-target lesion, or the appearance of new lesions.
