The Food and Drug Administration has approved 180 mg brigatinib (Alunbrig) tablets for treatment of anaplastic lymphoma kinase–positive (ALK+) metastatic non–small cell lung cancer (NSCLC), expanding on previously available 30-mg tablets.*
The FDA granted accelerated approval to brigatinib in April for ALK+ NSCLC patients who were no longer responding to treatment with crizotinib. The recommended regimen is 90 mg orally once daily for the first 7 days, and if tolerated, an increase to 180 mg orally once daily.“With the approval of a 180-mg tablet, Alunbrig has become the only ALK inhibitor available as a one tablet per day dose that can be taken with or without food,” Ryan Cohlhepp, PharmD, vice president, U.S. Commercial, at Takeda Oncology said in a press release.
Approval of the regimen was based on objective response in the ongoing, two-arm, open-label, multicenter phase 2 ALTA trial, which enrolled 222 patients with metastatic or locally advanced ALK+ NSCLC who had progressed on crizotinib. Patients were randomized to brigatinib orally either 90 mg once daily or 180 mg once daily following a 7-day lead-in at 90 mg once daily. Of those in the 180-mg arm, 53% had an objective response, compared with 48% in the 90-mg arm.
Adverse reactions occurred in 40% of the patients in the 180-mg arm, compared with 38% in the 90-mg arm. The most common serious adverse reactions were pneumonia and interstitial lung disease/pneumonitis. Fatal adverse reactions occurred in 3.7% of the patients, caused by pneumonia (two patients), sudden death, dyspnea, respiratory failure, pulmonary embolism, bacterial meningitis and urosepsis (one patient each).
The ALTA trial is ongoing, and updated results will be presented at the World Conference on Lung Cancer in Yokohama, Japan, on Oct. 15-18, the company said in the press release.
