Alecensa van Chugai behaalt primair eindpunt van onderzoek ALEX
TOKYO–(BUSINESS WIRE)– Chugai Pharmaceutical Co., Ltd. (TOKYO:4519) heeft vandaag bekendgemaakt dat Alecensa als eerstelijnsbehandeling in het internationale derdefaseonderzoek ALEX naar de behandeling van ALK-positieve niet-kleincellige longkanker leidde tot een langere overleving zonder verergerd ziektebeeld in vergelijking met crizotinib. Het onderzoek is uitgevoerd door F. Hoffmann-La Roche Ltd. Het veiligheidsprofiel van Alecensa kwam overeen met het profiel dat in eerdere onderzoeken was gebleken, zonder nieuwe of onverwachte nadelige bijwerkingen.

TOKYO–(BUSINESS WIRE)– Chugai Pharmaceutical Co., Ltd. (TOKYO:4519) announced today that Alecensa as an initial (first-line) treatment showed that patients lived significantly longer without disease worsening (progression-free survival, PFS) compared to crizotinib in the ALEX Study, a global phase III study targeting ALK fusion gene positive non-small cell lung cancer (NSCLC), conducted by F. Hoffmann-La Roche Ltd. The safety profile of Alecensa was consistent with that observed in previous studies, with no new or unexpected adverse events. “Following the Japanese phase III J-ALEX study, the ALEX study, the head to head trial with crizotinib, Alecensa demonstrated a significant prolongation of PFS compared to crizotinib. This finding greatly encourages the patients suffering from ALK fusion gene positive NSCLC,” said Dr. Yasushi Ito, Senior Vice President, Head of Project & Lifecycle Management Unit. “We believe that Alecensa will also contribute to improving the outcomes for overseas patients from first line therapy in the future.” The ALEX study was an open-label, randomized global phase III study that compares the efficacy and safety between both monotherapy of Alecensa and crizotinib. The ALEX study enrolled treatment-naïve 303 patients with ALK fusion gene positive NSCLC. The subjects were allocated to either the Alecensa arm or the crizotinib arm in a one to one ratio. The primary endpoint of the ALEX study was PFS as assessed by the investigator. The secondary endpoints included Independent Review Committee-assessed PFS, overall survival, objective response rate, duration of response, safety, and other endpoints. The full data of the ALEX study will be presented at a future medical meeting and submitted to global health authorities, including the United States Food and Drug Administration. Alecensa is a highly selective oral ALK inhibitor created by Chugai. It has been reported that approximately five percent of patients with NSCLC express a chromosomal rearrangement which leads to fusion of the ALK gene with another gene. 1) ALK kinase signalling is constantly active in cells with such fusion genes, resulting in uncontrolled growth of tumour cells and transforming the cells into tumour cells. 2, 3) Alecensa exerts its anti-tumour effect by selectively inhibiting ALK kinase activity to inhibit tumour cell proliferation and induce cell death. 4)In addition, Alecensa is not recognized by the active efflux system in the blood brain barrier which actively pumps molecules out of the brain. Thus, Alecensa is able to remain active in the central nervous system and has proven activity against brain metastases. Alecensa is currently approved in the United States, Kuwait, Israel, Hong Kong, Canada, South Korea, Switzerland, India, the EU, Australia and Taiwan for the treatment of adult patients with ALK-positive, metastatic (advanced) NSCLC who have progressed on or those intolerant to crizotinib. In Japan, “Alecensa capsule 150mg” is available to patients with “ ALK fusion gene positive unresectable, recurrent/advanced NSCLC” and is marketed by Chugai.
