with a solid tumor that has failed standard therapy or for which no standard therapy
is available, and evidence of progressive disease

- Part A only: Patients must have histological or cytological evidence of a solid
tumor which is advanced and/or metastatic

- Part B only: Patient who have failed first-line therapy/standard of care and
have histological or cytological evidence of a cancer type for which evidence of
activity was observed during Part A or for which preclinical evidence of
potential activity has been observed

- Have the presence of measurable or nonmeasurable disease as defined by the Response
Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST 1.1)

- Part A only: Patients may have measurable or nonmeasurable disease

- Part B: Patients must have measurable disease
