Brigatinib Shows Promise in ALK-Positive NSCLC After Crizotinib Therapy

Excerpt:

“The investigational tyrosine kinase inhibitor (TKI) brigatinib offered good response rates in a pivotal phase II trial of patients with ALK-positive non–small-cell lung cancer (NSCLC) whose disease progressed on crizotinib. The results were presented at the 2016 American Society of Clinical Oncology (ASCO) Annual Meeting, held June 3–7 in Chicago (abstract 9007).

“ ‘Most ALK-positive NSCLC patients treated with crizotinib eventually progress, often due to acquired ALK resistance mutations and/or poor CNS drug penetration,’ said Dong-Wan Kim, MD, PhD, of Seoul National University Hospital in South Korea, who presented the study.

“Brigatinib, a next-generation ALK TKI designed to have broad activity against resistant ALK mutants, showed promising clinical activity in a phase I/II study of crizotinib-treated ALK-positive NSCLC patients. The new open-label phase II ALTA study included 222 patients with locally advanced or metastatic NSCLC who had progressive disease on crizotinib. Patients were randomized to two brigatinib treatment regimens: group A (112 patients) received oral brigatinib 90 mg once per day, and group B (110 patients) received the same dose for 7 days followed by 180 mg once per day.”

ARIAD Presents Long-Term Phase 1/2 Trial Follow up on Investigational Drug Brigatinib with Median Time on Treatment of 17 Months in ALK+ NSCLC Patients

Excerpt:

ARIAD Pharmaceuticals, Inc.(NASDAQ:ARIA) today announced updated clinical data on its investigational tyrosine kinase inhibitor (TKI), brigatinib, in patients with anaplastic lymphoma kinase-positive (ALK+) advanced non-small cell lung cancer (NSCLC) from an ongoing Phase 1/2 trial. The current results include more mature efficacy and safety data for brigatinib, including updated response rates and median duration of response in ALK+ NSCLC patients.

“The updated Phase 1/2 results are being presented today at the 2016 American Society of Clinical Oncology (ASCO) annual meeting in Chicago.”

ARIAD Presents Updated Phase 1/2 Clinical Data on Brigatinib in Patients with ALK+ Non-Small Cell Lung Cancer

Excerpt:

ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced updated clinical data on its investigational tyrosine kinase inhibitor, brigatinib, in patients with advanced malignancies, including anaplastic lymphoma kinase positive (ALK+) non-small cell lung cancer (NSCLC), from an ongoing Phase 1/2 trial. This report includes updated data on the brigatinib safety profile and pharmacokinetics (PK) from all patients treated in the trial, with a focus on brigatinib clinical activity in patients with ALK+ NSCLC, including those with intracranial CNS metastases at study entry. The report also details overall survival outcomes of patients in the study.”

Promising Trial of Brigatinib Shows All Next-Gen ALK Inhibitors May Not Be Created Equal

“Phase I/II clinical trial results reported at the American Society for Clinical Oncology (ASCO) Annual Meeting 2015 show promising results for investigational drug brigatinib against ALK+ non-small cell lung cancer (NSCLC), with 58 of 78 ALK+ patients responding to treatment, including 50 of 70 patients who had progressed after previous treatment with crizotinib, the first licensed ALK inhibitor. Progression-free survival (PFS) in patients previously treated with crizotinib was 13.4 months.

” ‘Although still only in an early phase trial, brigatinib is showing an objective response rate in approximately 70 percent of ALK-positive post-crizotinib and it’s showing about a year of progression-free survival. These results are among the best in the field, offering a lot of hope to people with ALK-positive ,’ says D. Ross Camidge, MD, PhD, director of thoracic oncology at the University of Colorado Cancer Center and the trial’s principal investigator.”


Brigatinib Achieves Brain Metastases Control for Over 80% of ALK-Positive NSCLC Patients

“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.”
