    Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) announced that Chugai Pharma Taiwan Ltd., a wholly owned subsidiary of Chugai, obtained approval from the Taiwan Food and Drug Administration (TFDA), for “Alecensa®,” anaplastic lymphoma kinase (ALK) inhibitor, for the treatment of “patients with ALK-positive, advanced non-small cell lung cancer (NSCLC).”
    “The results of the J-ALEX study conducted by Chugai and the ALEX study conducted overseas showed that Alecensa will greatly contribute to the treatment of patients who receive at an early stage.” said Dr. Yasushi Ito, Chugai’s Senior Vice President, Co-Head of Project & Lifecycle Management Unit. “Following approval for first line treatment in the US and the EU in 2017, it is a great pleasure for Chugai that Alecensa has been approved for primary treatment in Taiwan followed by Japan and South Korea in the Asia region.”
    This approval is based on results from the phase III ALEX study. The ALEX study evaluates the efficacy and safety of Alecensa compared with crizotinib in people with ALK-positive NSCLC who had not received prior systemic therapy (first-line).
    In the study, Alecensa significantly reduced the risk of disease worsening or death by 47% (primary endpoint, HR=0.53, 95%CI: 0.38-0.73, stratified log-rank test, p<0.0001) compared to crizotinib as assessed by independent review committee. Median progression-free survival (PFS) was 25.7 months (95%CI: 19.9-not estimable) for people who received Alecensa compared with 10.4 months (95%CI: 7.7-14.6) for people who received crizotinib.
    The safety profile of both drugs was consistent with that observed in previous studies, with no new findings.
    In addition, Alecensa significantly reduced the risk of the cancer spreading to or growing in the brain or central nervous system (CNS) compared to crizotinib by 84% (HR=0.16, 95%CI: 0.10-0.28, stratified log-rank test, p<0.0001). This was based on a time to CNS progression analysis in which there was a lower risk of progression in the CNS as the first site of disease progression for people who received Alecensa (12%) compared to people who received crizotinib (45%).
