What was measured

IDCR is defined as the DCR based on lesions in brain (target, non-target lesions and new lesions, if applicable) and calculated as the percentage of patients with a best overall response of CR or PR or SD (or non-CR/nonPD) in the brain per modified RECIST 1.1 as assessed by BIRC neuro-radiologist. CR: Disappearance of all lesions with lymph nodes measuring \< 10 mm. PR: At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. SD: Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease

Analysis population: The Full Analysis Set (FAS) consisted of all patients to whom study treatment had been assigned by randomization. Patients with measurable brain disease and who had a baseline and at least one post-baseline scan

Groups in this outcome

Ceritinib

Ceritinib administered continuously through oral dosing at a dosage of 750 mg once daily in fasted state

Chemotherapy

Pemetrexed plus cisplatin or carboplatin (based on Investigator's choice) for 4 cycles (Induction) followed by pemetrexed as single agent (Maintenance)
