RESULTS OF A GLOBAL PHASE II STUDY WITH CRIZOTINIB IN ADVANCED ALK-POSITIVE NON-SMALL-CELL LUNG CANCER (NSCLC)

7533 Background: Approximately 3–5% of NSCLC harbors ALK gene rearrangements. Crizotinib is a first-in-class, oral, small-molecule competitive ALK inhibitor with anti-MET activity. Methods: PROFILE 1005 is an ongoing global, multicenter, open-label, single-arm, phase II study evaluating the safety and efficacy of crizotinib (250 mg BID in 3-week cycles) in patients with advanced ALK-positive NSCLC who progressed after ≥1 chemotherapy for recurrent/advanced/metastatic disease. Tumor response was evaluated by RECIST 1.1 every 6 weeks. Patient-reported symptoms and global quality of life (QOL) were assessed using the EORTC QLQ-C30 and LC-13 at baseline, day 1 each cycle and at end of treatment. Results: As of June 2011, 439 patients were evaluable for safety and 255 patients for tumor response. Median age was 53 years. The majority of patients were female (53%), never smokers (65%), and had adenocarcinoma (92%), ECOG PS 0–1 (83%) and ≥2 prior chemotherapy regimens (85%). Among patients evaluable for efficacy...
