1300P - Intracranial efficacy of brigatinib (BRG) vs crizotinib (CRZ): Updated results from the ALTA-1L trial
- Sanjay Popat (London, United Kingdom)
Abstract
Background
BRG, a next-generation ALK tyrosine kinase inhibitor (TKI), has robust overall and intracranial efficacy in CRZ-resistant ALK+ NSCLC. At first ALTA-1L interim analysis (IA) in patients (pts) with TKI-naive ALK+ NSCLC, the primary endpoint, blinded independent review committee (BIRC)-assessed PFS, was met (HR, 0.49;
Methods
This open-label, multicenter study enrolled pts with TKI-naive stage IIIB/IV ALK+ NSCLC. Pts were stratified by presence of baseline (BL) brain metastases and history of chemotherapy for advanced disease and randomized 1:1 to BRG 180 mg qd with 7-day lead-in at 90 mg or CRZ 250 mg bid. Primary endpoint was BIRC-assessed PFS (RECIST v1.1). Secondary endpoints included intracranial ORR (iORR) and iPFS. The second IA was planned at ∼75% of 198 expected PFS events.
Results
Of 275 randomized pts (BRG/CRZ, n=137/138), 34%/36% had BL brain metastases (BIRC-assessed). 13%/14% had prior brain radiotherapy, with whole brain radiation and stereotactic radiosurgery balanced across arms. At data cutoff (28 June 2019; median follow-up [BRG/CRZ], 24.9/15.2 mo, 150 events), iPFS in the ITT population remained significantly improved with BRG (HR, 0.45 [95% CI, 0.29–0.69]; log-rank NR, not reached a95% CI; bLog-rank; cCochran-Mantel-Haenszel test.

Conclusions
BRG demonstrated superior intracranial activity vs CRZ in pts with ALK TKI-naive ALK+ NSCLC in ALTA-1L.
