Initial US Approval
- 20171
Indications
Metastatic ALK+ NSCLC:
- The treatment of adult patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) as detected by an FDA-approved test1
Recommended Dose/Route
- Brigatinib 90 mg orally once daily for the first 7 days; then increase the dose to 180 mg orally once daily.1
Pivotal Study
ALTA 1L (NCT02737501)2
- Treatment setting: TKI-naive advanced ALK+ NSCLC
- Key Inclusion Criteria: Eligible participants in ALTA 1L included patients with advanced ALK-positive NSCLC who had not previously received an ALK-targeted therapy. Eligible patients were allowed to have up to 1 prior regimen of chemotherapy in the locally advanced or metastatic setting and were required to have an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-2.
- Treatment: Brigatinib 180 mg orally once daily with a 7-day lead-in at 90 mg once daily.
ALTA (NCT02094573)3
- Treatment setting: locally advanced or metastatic ALK+ NSCLC following progression on crizotinib.
- Key Inclusion Criteria: Participants in ALTA included patients with advanced or metastatic ALK-positive NSCLC who had experienced disease progression while receiving treatment with crizotinib and an ECOG Performance Status of 0-2.
- Treatment: Brigatinib 90 mg once daily (90 mg arm; n = 112) or 180 mg once daily following a 7-day lead-in at 90 mg once daily (90→180 mg arm; n = 110).
