- Analysis Also Demonstrated Intracranial Median Progression-Free Survival (PFS) of 18.4 Months
- 55 Percent Confirmed Systemic Objective Response Rate
- Investor and Analyst Webcast to be Held Today at 4:00 p.m. Central European Time (10:00 a.m. Eastern Time)
CAMBRIDGE, Mass. & VIENNA--(BUSINESS WIRE)-- ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA), 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."
The ALTA Trial
The ALTA (ALK in Lung Cancer Trial of AP26113) trial enrolled 222 patients with ALK+ NSCLC who had been treated with and experienced disease progression on their most recent crizotinib therapy. Patients were randomized one-to-one to receive either 90 mg of brigatinib once per day (QD) (Arm A), or 180 mg QD, preceded by a lead-in dose of 90 mg QD for seven days (Arm B). In addition, patients were stratified by presence of brain metastases at baseline and best response to prior crizotinib therapy.
The primary endpoint of the ALTA trial is investigator-assessed confirmed objective response rate (ORR) as measured by the Response Evaluation Criteria in Solid Tumors (RECIST). Key secondary endpoints include PFS, confirmed ORR assessed by an IRC, overall survival (OS), CNS response and PFS, duration of response, safety and tolerability.
Key Data from the ALTA Trial Update
Brigatinib Efficacy and Safety in ALK+ NSCLC Patients:
Clinical Data as of May 31, 2016 with IRC Data as of July 13, 2016
"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."
The poster presentation, "Brigatinib in Crizotinib-Refractory ALK+ NSCLC: Central Assessment and Updates from ALTA, a Pivotal Randomized Phase 2 Trial," (Abstract #4046, Poster ID P3.02a-013) will be presented today, Wednesday, December 7, 2016 from 14:30 - 15:45 GMT.
Brigatinib is an investigational, targeted cancer medicine discovered internally at ARIAD. Brigatinib received Breakthrough Therapy designation from the FDA for the treatment of patients with ALK+ NSCLC whose tumors are resistant to crizotinib, and was granted orphan drug designation by the FDA for the treatment of ALK+ NSCLC. The FDA has accepted brigatinib's New Drug Application and has granted ARIAD's request for Priority Review and set an action date of April 29, 2017 under the Prescription Drug User Fee Act (PDUFA). ARIAD intends to submit a Marketing Authorization Application (MAA) for brigatinib to the European Medicines Agency (EMA) in early 2017.
ARIAD has also initiated the Phase 3 ALTA 1L trial to assess the efficacy and safety of brigatinib in comparison to crizotinib in patients with locally advanced or metastatic ALK+ NSCLC who have not received prior treatment with an ALK inhibitor. More information on brigatinib clinical trials, including the expanded access program (EAP) for ALK+ NSCLC can be found here.
