Brief Summary: Currently, there is a lack of high-quality clinical evidence for subsequent treatment options for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) after first-line treatment, especially for subsequent treatment after first-line therapy combined with PD-1 inhibitors. Increasing evidence suggests that low-dose radiation (LDRT) can reshape the tumor microenvironment.Cadonilimab is a bispecific antibody that specifically binds to CTLA-4 and PD-1 proteins in the human body. Considering that low-dose radiotherapy and cadonilimab both have immunomodulatory effects, this study intends to select recurrent metastatic HNSCC patients who have failed first-line and above treatment to explore the safety and efficacy of cadonilimab combined with low-dose radiotherapy.
Detailed Description: Currently, there is a lack of high-quality clinical evidence for subsequent treatment options for recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) after first-line treatment, especially for subsequent treatment after first-line therapy combined with PD-1 inhibitors. Increasing evidence suggests that low-dose radiation (LDRT) can reshape the tumor microenvironment, polarize macrophages towards M1, and M1 macrophages secrete chemokines to promote the recruitment of effector T cells while inducing vascular normalization. Cadonilimab is a bispecific antibody that specifically binds to CTLA-4 and PD-1 proteins in the human body. It is the first approved PD-1/CTLA-4 bispecific antibody. In June 2022, cadonilimab was approved by the NMPA for the treatment of recurrent or metastatic cervical cancer patients after platinum-based chemotherapy failure. The drug is currently undergoing clinical trials for other types of cancers, including non-small cell lung cancer, hepatocellular carcinoma, gastric cancer, esophageal cancer, and nasopharyngeal cancer. In view of the subsequent treatment strategies for recurrent metastatic HNSCC after first-line treatment progress, there is still a lack of high-level evidence-based medical evidence to confirm the best recommendation for subsequent treatment. Considering that low-dose radiotherapy and cadonilimab both have immunomodulatory effects, this study intends to select recurrent metastatic HNSCC patients who have failed first-line and above treatment to explore the safety and efficacy of cadonilimab combined with low-dose radiotherapy.
