Brigatinib is an investigational oral tyrosine kinase inhibitor with preclinical activity against the oncogenic ALK fusion protein and mutants resistant to crizotinib.


Pts with advanced malignancies received oral brigatinib (30–300 mg total daily) in this ongoing phase 1/2, single-arm, open-label, multicenter study (N = 137; NCT01449461). Efficacy (per RECIST v1.1) in ALK+ NSCLC pts and safety in all pts are reported.


Among ALK+ NSCLC pts (n = 79), median age was 54 (29–83) years, 49% were female, and 90% had received crizotinib. As of February 17, 2015, 45/79 (57%) pts remained on study; median time on treatment was 12.6 months (1 day to 35.5 months). Evaluable ALK+ NSCLC pts with prior crizotinib (n = 70) had an objective response rate (ORR) of 71% and median progression-free survival (PFS) of 13.4 months (table). In a post hoc independent radiological review of pts with brain metastases at baseline, as of February 9, 2015: 8/15 (53%) pts with measurable (≥10 mm) brain lesions (including 5/9 [56%] pts with no prior brain radiotherapy) had an intracranial objective response; intracranial disease control rate was 87%. For all pts with an intracranial response (n = 19), median duration of intracranial response was 18.9 months. Treatment-emergent adverse events (TEAEs) in ≥30% of all 137 pts, mostly grades 1/2, were: nausea 52%; fatigue 42%; diarrhea 40%; headache 33%; cough 32%. Serious TEAEs (≥2% frequency; any cause) were: dyspnea 7%; pneumonia 6%; hypoxia 5%; pulmonary embolism 3%; pyrexia 2%. 133OT1 Table: Brigatinib efficacy in evaluable ALK+ NSCLC patients

Brigatinib showed antitumor activity in crizotinib-treated (71% ORR; median PFS, 13.4 months) and crizotinib-naive (100% ORR) ALK+ NSCLC pts, including pts with brain metastases at baseline (53% intracranial ORR in pts with measurable brain lesions). A pivotal, randomized, phase 2 trial of brigatinib in pts with crizotinib-resistant ALK+ NSCLC has completed accrual.
