All patients will be assessed at Screening and at specified times during the conduct of the study using standard clinical and laboratory assessment. Patients will also be assessed for tumor response per standard of care after the Screening Period. Response to treatment will be assessed by computerized tomography (CT), magnetic resonance imaging (MRI) and bone scans as appropriate. Patients will continue receiving their appropriate cycles of study treatment until tumor progression or adverse events (AEs) occur which necessitate discontinuing therapy as determined by the Investigator.
