Participant gender:
All
Summary
AK105 is a humanized monoclonal antibody that specially binds to PD-1. Anlotinib is a small molecule tyrosine kinase inhibitor. Based on the mechanism study, tumor vascular abnormalities promote tissue hypoxia and increase lactic acid, thereby activating immunosuppression and inhibiting T cell function. Anti-angiogenic drugs enhance the infiltration of effector immune cells by inducing normalization of blood vessels and reducing immunosuppression.

According to the judgement of the researchers, there are other factors that subjects
are not suitable for the study.
