- Alunbrig demonstrated statistically superior progression-free survival vs crizotinib in patients with ALK+ NSCLC
- Alunbrig previously received accelerated approval from the FDA for ALK+ advanced NSCLC
- The drug was also awarded Breakthrough Therapy Designation and Orphan Drug Status by the FDA
Takeda Pharmaceutical Company Limited (TSE: 4502) announced on 7/25/18 that the global, randomized, Phase 3 ALTA-1L (ALK in Lung Cancer Trial of AP26113 in 1st Line) trial met its primary endpoint at the first pre-specified interim analysis, with ALUNBRIG (brigatinib) demonstrating a statistically significant improvement in progression-free survival (PFS) compared to crizotinib in adults with anaplastic lymphoma kinase-positive (ALK+) locally advanced or metastatic non-small cell lung cancer (NSCLC) who had not received a prior ALK inhibitor. The trial was designed to assess the efficacy and safety of ALUNBRIG in comparison to crizotinib based on evaluation of the primary endpoint of PFS, or length of time from the start of treatment that a patient lives without the disease getting worse. ALUNBRIG is currently not approved as frontline therapy.
“This represents a major milestone for the ALUNBRIG program. Our goal with ALUNBRIG is to improve the lives of patients with ALK+ NSCLC by furthering the available therapeutic options,” said Jesús Gomez-Navarro, M.D., Vice President, Head of Oncology Clinical Research and Development, Takeda. “We are encouraged by the data, which demonstrated a statistically significant improvement in progression-free survival versus crizotinib in patients with ALK+ advanced NSCLC, and look forward to beginning discussions with regulatory authorities as we seek to expand ALUNBRIG’s indication into the frontline setting.”
The Phase 3 ALTA-1L (ALK in Lung Cancer Trial of AP26113 in 1st Line) trial of ALUNBRIG in adults is a global, ongoing, randomized, open-label, comparative, multicenter trial, which enrolled 275 patients with ALK+ locally advanced or metastatic NSCLC who have not received prior treatment with an ALK inhibitor. Patients received either ALUNBRIG, 180 mg once daily with seven-day lead-in at 90 mg once daily, or crizotinib, 250 mg twice daily. Independent Review Committee (IRC)-assessed progression-free survival (PFS) was the primary endpoint. Secondary endpoints included objective response rate (ORR) per RECIST v1.1, intracranial ORR, intracranial PFS, overall survival (OS), safety and tolerability. A total of approximately 198 PFS events are planned at the final analysis of the primary endpoint in order to demonstrate a minimum of six months PFS improvement over crizotinib. The trial is designed with two pre-specified interim analyses for the primary endpoint – one at 50 percent of planned PFS events and one at 75 percent of planned PFS events.
Alunbrig is a targeted cancer medicine discovered by ARIAD Pharmaceuticals, Inc., which was acquired by Takeda in February 2017. In April 2017, Alunbrig received Accelerated Approval from the U.S. Food and Drug Administration (FDA) for ALK+ metastatic NSCLC patients who have progressed on or are intolerant to crizotinib. This indication is approved under Accelerated Approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
Alunbrig 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, ROS1+ and EGFR+ NSCLC. A Marketing Authorization Application (MAA) for ALUNBRIG was submitted to the European Medicines Agency (EMA) in February 2017.
