Number of Participants With Best Overall Response - Dose Escalation Stages 1, 1A and 1B Up to 30 days after last dose (last dose = up to Cycle 15, cycle length = 28 days) Tumor response was assessed using Response Evaluation Criteria in Solid Tumors (RECIST). Complete response (CR) = disappearance of all target and non-target lesions. Partial Response (PR) = at least 30 percent (%) decrease in sum of the longest diameter of measured lesions taking as reference the baseline sum of the longest diameter. Progressive disease (PD) = at least 20% increase in the sum of the longest diameter of measured lesions taking as reference the smallest sum of the longest diameter since treatment start or appearance of one or more new lesions. Stable disease (SD) = neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of the longest diameter since treatment start.
Duration of Objective Response - Dose Escalation Stages 1, 1A and 1B Up to 30 days after last dose (last dose = up to Cycle 15, cycle length = 28 days) Duration of objective response was defined as the time from first occurrence of a documented objective response (CR or PR) until the time of disease progression, as determined by investigator review of tumor assessments using RECIST, or death from any cause during the study (within 30 days after the last dose of study treatment). CR = disappearance of all target and non-target lesions. PR = at least 30 % decrease in sum of the longest diameter of measured lesions taking as reference the baseline sum of the longest diameter. PD = at least 20% increase in the sum of the longest diameter of measured lesions taking as reference the smallest sum of the longest diameter since treatment start or appearance of one or more new lesions.
Progression-Free Survival (PFS) - Dose Escalation Stages 1, 1A and 1B Up to 30 days after last dose (last dose = up to Cycle 15, cycle length = 28 days) PFS was the time from study treatment initiation to the first occurrence of disease progression, as determined by investigator review of tumor assessments using RECIST, or death from any cause during the study (within 30 days after the last dose of study treatment). PD = at least 20% increase in the sum of the longest diameter of measured lesions taking as reference the smallest sum of the longest diameter since treatment start or appearance of one or more new lesions.
