Background Pumitamig (BNT327) is a bispecific antibody drug that targets PD-L1 and VEGF-A in a research context derived from the unmet need that exists in the treatment of solid tumors such as small-cell carcinoma (SCLC) . As a highly malignant subtype of lung cancer, SCLC has the characteristics of rapid growth and easy metastasis. About 70% of patients are in an extensive stage when they are diagnosed. Traditional treatment methods have limited effect, and the 5-year survival rate has been low for a long time. PD-L1 promotes immune escape by inhibiting immune cell function in the tumor microenvironment, while VEGF-A supports tumor growth and metastasis by driving tumor angiogenesis. By simultaneously blocking these two key targets, Pumitamig aims to restore effector T cell activity, inhibit tumor angiogenesis, and break the tumor immune escape mechanism to achieve a multidimensional attack on tumors.
