ARIAD Pharma Updates Clinical Data On Brigatinib

(RTTNews) - ARIAD Pharmaceuticals, Inc. (ARIA) announced updated clinical data on brigatinib, its investigational anaplastic lymphoma kinase (ALK) inhibitor, from the pivotal ALTA trial in patients who had experienced disease progression on crizotinib therapy. The data show that, of patients on the 180 mg regimen (Arm B) with a median follow-up of 8.3 months, 54 percent achieved a confirmed objective response, the trial's primary endpoint.

In this arm, the median progression free survival (PFS) exceeded one year (12.9 months) in this post-crizotinib setting. Additionally, a 67 percent confirmed intracranial objective response rate (ORR) was achieved in patients with measurable brain metastases. These data will be presented today, for the first time, at the Annual Meeting of the American Society of Clinical Oncology (ASCO), reflecting an additional 12 weeks of patient follow up and new data on central nervous system (CNS) activity compared to the abstract released last month.
