(DLT defined specifically for following cases: \>=Grade 3 liver AE requiring recovery period of more than 7 days or to Grade 1 or less or Grade 2 with liver metastases ; \>=Grade 3 lipase and/or amylase elevation with confirmation of pancreatitis. An isolated lipase and/or amylase elevation of \>=Grade 3 without clinical/radiological evidence of pancreatitis was not classified as DLT); and AEs assessed by investigators to be exclusively related to the participant's underlying disease or medical condition/concomitant treatment are not considered as DLTs.
Phase 2: Number of Participants Who Were Progression-free at 12 Weeks (PFS Status) as Assessed by the Investigator According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1	At 12 weeks post first-dose in Phase 2	PFS status was evaluated by the number of participants who were progression-free at 12 weeks according to RECIST Version 1.1.

Partial response (PR) defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameters, or Stable Disease (SD) defined as any cases that do not qualify for either partial response or progressive disease (an increase of at least 20% in the sum of the diameters of target lesions, taking as reference the smallest sum of the diameters of target lesions recorded since treatment started)12 weeks after start of treatment or later.
