What was measured

DOR is defined as the time from date of first documented CR or PR to date of first documented disease progression (measured by investigator assessment per RECIST 1.1) or death due to any cause. 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. If a patient had not had an event, DOR was censored at the date of last adequate tumor assessment. Patients who had never achieved a best overall response of CR or PR were excluded from the analysis. The distribution function of DOR was estimated using the KM method.

Analysis population: The Full Analysis Set (FAS) consisted of all patients to whom study treatment had been assigned by randomization. Patients with confirmed CR or PR by investigator assessment.

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)
