Abstract 3103


The CNS is often a site of first disease progression in CRZ-treated ALK+ NSCLC pts; we report BRG efficacy and safety in pts with CRZ-refractory advanced ALK+ NSCLC in the phase 2 ALTA trial who had baseline CNS metastases.


ALTA (NCT02094573) permitted baseline CNS disease (including pts with prior whole brain radiotherapy/stereotactic radiosurgery and asymptomatic untreated pts). 222 pts stratified by presence of brain metastases and best response to prior CRZ were randomized 1:1 to receive BRG 90 mg qd (arm A, n = 112) or 180 mg qd with a 7-day lead-in at 90 mg (arm B, n = 110). This analysis included an exploratory competing risks analysis to estimate cumulative incidence of CNS progression vs non-CNS progression vs death in pts with baseline brain metastases.


80 (71%)/73 (66%) pts in A/B had baseline brain metastases per independent review committee (median age, 49/55 years; 76%/74% had received chemotherapy). As of 21 Feb 2017, median follow-up for pts with brain metastases was 17.7 months; 34%/40% continued to receive BRG in A/B. Table shows intracranial efficacy. 5 pts with measurable baseline brain metastases in A had progression in the brain (≥20% growth in target lesions or new lesions) while receiving BRG 90 mg qd and escalated to 180 mg qd with ≥1 additional scan; all 5 had a reduction in measurable lesions after escalation (−14% to − 100%). While pts without baseline brain metastases did not have routine brain MRI scans, 3/32 and 1/36 pts without baseline brain metastases per investigators in A and B, respectively, had a new brain lesion identified by MRI.


In this update of ALTA, BRG continued to show robust intracranial efficacy in ALK+ NSCLC pts with baseline brain metastases, particularly at 180 mg (with lead-in), with a higher intracranial response rate and a numerically lower incidence of disease progression in the CNS and outside the CNS, compared to 90 mg.Table:
