  Hide Outcome Measure 3

Measure Type Secondary
Measure Title Percentage of Participants With Objective Response
Measure Description Percentage of participants with objective response based assessment of confirmed complete response (CR) or confirmed partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST). CR was the disappearance of all target lesions and non target lesions. PR was at least a 30 percent (%) decrease in sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.
Time Frame Baseline, every 2 months until tumor progression or death (up to Month 80)  
Safety Issue No
