Lung cancer is the malignant tumor with the highest mortality and morbidity in China, of which non-small cell lung cancer (NSCLC) accounts for about 80%-85% of lung cancers. Anaplastic lymphoma kinase (ALK) is one of the important oncogenic drivers of NSCLC, and ALK mutations are found in 5%-7% of NSCLC patients . Because this mutation is more common in young, non-smoking or light-smoking lung adenocarcinoma patients, it is easier to achieve 5-year survival after using targeted drugs than other gene mutations. ALK fusion mutation is also known as "diamond mutation".
△Mechanism of action of Ensatinib
Ensatinib hydrochloride is a new-generation, potent and highly selective new-generation ALK inhibitor. It is a brand-new innovative drug with completely independent intellectual property rights jointly developed by Betta Pharmaceuticals and its holding subsidiary Xcovery. In December 2018 , the drug registration application of ensatinib for patients with ALK -positive locally advanced or metastatic non-small cell lung cancer who had progressed after receiving crizotinib treatment or who were intolerant to crizotinib received national approval. Accepted by the Food and Drug Administration. In February 2019 , ensatinib was included in the priority review list by the Center for Drug Evaluation (CDE) of the State Food and Drug Administration. Since then, the clinical verification and registration on-site inspection organized by the Center for Food and Drug Inspection and Inspection ( CFDI ) of the State Food and Drug Administration have been completed successively .
The domestic phase II registration clinical study of ensatinib hydrochloride was led by Professor Zhang Zhang from Sun Yat-sen University Cancer Center, and a total of 27 domestic medical centers participated. The results of the study were published in full in the internationally renowned medical academic journal "The Lancet Respiratory Medicine" in October 2019 . Subsequent updated data showed that the overall ORR of crizotinib-resistant patients treated with ensatinib was 52.6% , the disease control rate was 87.8% , the median PFS was 11.2 months, the intracranial ORR was 71.4% , and the intracranial disease was 71.4%. The control rate was 95.2% . Studies have shown that ensatinib has more advantages compared with similar imported drugs in efficacy, especially in patients with intracranial metastasis, it has a higher response rate and has a good and controllable safety.
