What was measured

TTR is defined as the time from date of randomization to date of first documented response (CR or PR) measured by BIRC assessment per RECIST 1.1. 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. Patients who had not achieved a confirmed CR or PR were censored at the last adequate tumor assessment date when they had not had a PFS event or at maximum follow-up when they had had a PFS event.

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 BIRC 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)
