Description
Ba/F3 cells expressing EML4-ALK variant 1 with ALK G1202R mutation were assessed for ceritinib sensitivity. Crizotinib was shown to confer significantly more potency than ceritinib (43-fold decrease in IC50). EML4-ALK variant 3 NSCLC cell line H2228 was used in SCID mouse xenografts which were exposed to increasing crizotinib up to 100 mg/kg. Within 40 days tumors progressed, and progressed tumors were assayed for ALK mutation. Of 80 tumors, 6 had ALK mutation and 3 of these were G1202R. Treatment of crizotinib progressed tumors with ceritinib resulted in tumor growth which did not differ appreciably from crizotinib or vehicle treatment of these tumors.
