Combined Statin and PD-1/PD-L1 Inhibitors in Treating Non-small Cell Lung Cancer

Lung Cancer Clinical Trial

Official title: Statin Combined With PD-1/PD-L1 Inhibitors in Treating NSCLC

Status Active, not recruiting

Clinical Trial Summary

This prospective observational study was designed to evaluate the safety and efficacy of PD-1/PD-L1 inhibitors in combination with statins compared with treatment with PD-1/PD-L1 inhibitors alone in advanced NSCLC patients. Participants will receive either immunotherapy + statin or immunotherapy until progressive disease (PD) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Treatment can be continued until persistent radiographic PD or symptomatic deterioration.

Clinical Trial Description

Statin is an inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (CoA) reductase (HMGCR), the rate-limiting enzyme of the mevalonate (MVA) pathway for the cholesterol biosynthesis. Statins reportedly target the immune microenvironment through cytokines or chemokines and immune checkpoints. In a B16 melanoma lung metastatic model, statin lowers PD-1 expression in CD8+ T cells and effectively restores antitumor activity. In colorectal cancers model, simvastatin acts as a potential therapeutic drug for immunotherapy, which suppresses lncRNA SNHG29-mediated YAP activation and promotes anti-tumor immunity by inhibiting PD-L1 expression. Some retrospective observational studies have reported that baseline statin use was associated with improved clinical activity of PD-1/PD-L1 inhibitors in non-small cell lung cancer (NSCLC) patients. These findings support the adjuvant role of statins combined with immunotherapy. Statin therapy may be a combination tool for cancer immunotherapy in patients with NSCLC. Data from already completed clinical trials are not always supportive. These findings should be validated in further prospective studies with larger sample sizes. More clinical trials are needed to explore the right drug type, dose, frequency, duration, and suitable participator. Thus, this prospective observational study was designed to evaluate the safety and efficacy of PD-1/PD-L1 inhibitors in combination with statins compared with treatment with PD-1/PD-L1 inhibitors alone in advanced NSCLC patients. ;
