Number/extent of lesions with at least a moderate update of any of the RLIs according to visual assessment scoring scale on each corresponding targeted PET/CT scan based on blinded independent central review (BICR) assessment.
Percentage changes in quantitative PET/CT parameters (SUVmax, SUVmean, SUVpeak, target-positive Tumor Volume (target -TV), Total Lesion (target (TL-target)\] and changes in number of target-positive lesions (as per visual assessment) on each corresponding target PET/CT based on BICR.
