Rezivertinib

The incidence and mortality of lung cancer rank first among malignant tumors in China. Among them, non-small cell lung cancer (NSCLC) is the most important pathological type, accounting for 80%-85% of lung cancer patients, including adenocarcinoma, squamous cell carcinoma and other pathological subtypes. In recent years, with the discovery of epidermal growth factor receptor (EGFR) gene and the successful development of tyrosine kinase inhibitors (TKIs), the treatment efficacy of stage Ⅳ NSCLC patients with EGFR gene sensitive mutation has been greatly improved. As of August 23, 2023, the first generation EGFR-TKIs, gefitinib, icotinib, and erlotinib; the second generation EGFR-TKIs, afatinib and dacomitinib; and the third generation EGFR-TKIs, osimertinib, almonertinib, furmonertinib and befotertinib were all approved for marketing by China National Medical Products Administration (NMPA). In addition, multiple domestic third-generation EGFR-TKIs are undergoing clinical trials, such as rezivertinib (BPI-7711), limertinib (ASK120067), and oritinib (SH-1028). Meanwhile, mobocertinib and sunvozertinib, which targets EGFR 20ins mutations, were also approved by NMPA. With the increasing variety of EGFR-TKIs approved for marketing subsequently, it brings confusion to clinicians when choosing specific medications, and there is an urgent need to develop relevant treatment guidelines. Hence, the Medical Oncology Branch of China International Exchange and Promotive Association for Medical and Health Care and the Chinese Association for Clinical Oncologists convened experts to integrate the research results of various EGFR-TKIs, and proposed the "China clinical practice guideline for epidermal growth factor receptor tyrosine kinase inhibitors in stage Ⅳ non-small cell lung cancer (version 2023)", to provide reference for better clinical practice.
