“Brigatinib (AP26113), an investigational ALK tyrosine kinase inhibitor, demonstrated significant intracranial antitumor activity in patients with ALK-positive non–small cell lung cancer (NSCLC) and brain metastases, according to findings presented at the European Lung Cancer Conference.1
“A post hoc analysis conducted by Ariad Pharmaceuticals, the company developing brigatinib, looked at 49 NSCLC patients identified as having baseline brain metastasis. The analysis determined that intracranial disease control was achieved with brigatinib in 87% of patients with measurable brain metastases and in 87% of patients with nonmeasurable brain metastases. Intracranial response was reported in 53% of patients with measurable brain metastases and in 30% of patients with nonmeasurable lesions.
“Following treatment, 45 patients achieved median intracranial progression–free survival (PFS) of 22.3 months. The median duration of intracranial response was 18.9 months.
“Adverse events were mild to moderate in severity and included nausea, diarrhea, and fatigue that were reported by 29 (59%), 28 (57%), and 24 (49%) patients, respectively.”
