• Uncontrolled spinal cord compression

• ECOG performance status 0 or 1
• Estimated life expectancy of at least 3 months
• Patients who have progressed on or after all available standard therapies or for whom standard treatment is inappropriate
• Mandatory provision of archived or fresh tumor tissue in quantity sufficient to allow for retrospective confirmation of HER2 aberration or EGFR mutation
• A patient with a history of brain metastases must have had all lesions treated
