Overview

P-IL-2 + anti-PD-1 monoclonal antibody refers to a combination or a bispecific molecule that targets both the interleukin 2 (IL‑2) pathway and the programmed cell death protein 1 (PD‑1) immune checkpoint. These agents are designed to enhance antitumor immunity by simultaneously blocking PD‑1-mediated T cell inhibition and providing IL‑2 signaling to stimulate T cells and natural killer (NK) cells. Some molecules in this category are engineered as bispecific antibodies or immunocytokines that bind PD‑1 on T cells while delivering IL‑2 activity preferentially to tumor-reactive lymphocytes. This dual mechanism aims to overcome limitations of high-dose IL‑2 therapy (toxicity) and resistance to checkpoint inhibitors by focusing immune activation within the tumor microenvironment[4][5][8]. Developers include various biotechnology companies working on next-generation immunotherapies for cancer.
