Takeda, a rare cancer-focused innovative biotechnology company, today announced clinical data on brigatinib, its investigational anaplastic lymphoma kinase (ALK) inhibitor, from the pivotal ALTA trial in ALK-positive (ALK+) non-small cell lung cancer (NSCLC) patients who had experienced disease progression on crizotinib therapy. As of May 31, 2016, the data show that of patients on the 180-mg regimen with a median follow-up of 11 months, 55 percent achieved confirmed objective response as assessed by the investigator. In this arm, the median progression-free survival (PFS) was 15.6 months in this post-crizotinib setting, by both investigator and independent review committee (IRC) assessment. Additionally, in this arm, 67 percent of patients with measurable brain metastases achieved a confirmed intracranial objective response, and intracranial PFS was 18.4 months among patients with any brain metastases at baseline. These data will be presented today at the International Association for the Study of Lung Cancer (IASLC) 17th World Conference on Lung Cancer (WCLC) being held in Vienna.

“These updated ALTA trial data show that with additional follow-up, median progression-free survival from brigatinib given post-crizotinib is now 15.6 months, and that this is the same whether assessed by the investigators or an independent review committee,” said D. Ross Camidge, M.D., Ph.D., director of thoracic oncology at the University of Colorado. “Whether this is a reflection of broader suppression of potential resistance mutations, or its effects on protecting the central nervous system, or both, requires further investigation but by itself these progression-free survival data should be very encouraging for physicians and patients alike. These data really support the idea to pursue brigatinib, not just post-crizotinib, but also in the ongoing ALTA 1L study, which aims to assess its potential in the ALK-treatment naive setting.”

“We are encouraged by the maturing efficacy and safety profile of brigatinib in this later data cut, which adds three months of follow up compared to the data presented at ASCO,” stated Timothy P. Clackson, Ph.D., president of research and development and chief scientific officer at ARIAD. “These data are intended to be submitted to the European Medicines Agency in early 2017 for marketing approval. Pending regulatory review, we expect that brigatinib may become an important therapeutic option for the crizotinib-resistant population.”
