Summary

Lung cancer is the leading cause of death from cancer in China. In recent years, immune checkpoint inhibitor has gradually become a research hotspot, and it has continuously achieved huge breakthroughs. The FDA and NMPA have approved multiple PD-1/PD-L1 inhibitors for first-line or second-line treatment of advanced or metastatic NSCLC. But In clinical practice, there is still some controversy about PD-1 inhibitor monotherapy, especially for patients with low PD-L1 expression, the efficacy of monotherapy needs to be further improved. Strong genetic and functional evidence indicates that FGFR dysregulation can lead to the development and progression of cancer. Genetic alterations of FGFR1, FGFR2 and FGFR3 have been found in a variety of tumors. Squamous non-small cell lung cancer has about 13% of FGFR variants, while there are only 4% of any FGFR variants in lung adenocarcinoma. Studies of FGFR inhibitors in NSCLC show that AZD4575 has shown partial efficacy in FGFR partially mutated and expanded lung squamous cell carcinoma. FGFR pathway is involved in the regulation of the tumor immune microenvironment. In the tumor suppressor model of rectal cancer, it has been observed that FGFR2 overexpression promotes the expression of PD-L1 by activating JAK/STAT3 pathway, leading to tumor growth. In a lung cancer suppressor mouse model, the combination of FGFR inhibitor and PD-1 inhibitor can improve tumor remission and prolong survival. Based on the preliminary clinical data, this study assumes that Sintilimab(anti-PD-1) combined with Pemigatinib(FGFR inhibitor) can further improve efficay of advanced NSCLC with PD-L1 positive and FGFR1-3 mutation) including but not limited to FGFR amplification, rearrangement/fusion, mutation, etc.).
