Ariad Pharmaceuticals announced the initiation of the first part of a rolling New Drug Application (NDA) submission to the Food and Drug Administration (FDA) for its investigational agent, brigatinib, for the treatment of patients with anaplastic lymphoma kinase positive (ALK+) non-small cell lung cancer (NSCLC) who are resistant to crizotinib.

Brigatinib is currently being evaluated in a global Phase 2 trial, which reported positive preliminary results at this year’s American Society of Clinical Oncology annual meeting. Data showed that 54% of patients treated with brigatinib 180mg regimen achieved a confirmed objective response; the study’s primary endpoint. Brigatinib was found to have a tolerable safety profile. The Company has also initiated a Phase 3 trial to evaluate brigatinib in comparison to crizotinib.
