Incidence of adverse events, serious adverse events, adverse events meeting protocol-defined DLT criteria, severe adverse events, adverse events leading to study treatment or study discontinuation, and adverse events resulting in death. [ Time Frame: Throughout study to end of study treatment visit (Week 24 or +30 days after last study drug dose) ]

  20. Other prior malignancy active within the previous 3 years, except for local or organ confined early-stage cancer that has been definitively treated with curative intent, does not require ongoing treatment, has no evidence of residual disease and has a negligible risk of recurrence and is therefore unlikely to interfere with the primary and secondary endpoints of the study, including response rate and safety
  21. Symptomatic brain metastases or any leptomeningeal metastases that are symptomatic and/or require treatment. Patients with brain metastases are eligible if these have been treated (surgery, radiotherapy). Both surgery and or radiotherapy must have been completed at least 2 weeks before first dose of study treatment.
