L-BLP25 is an investigational MUC1 antigen-specific cancer immunotherapy that is designed to stimulate the body’s immune system to identify and target cells expressing the cell surface glycoprotein MUC1. MUC1 is expressed in many cancers, such as non-small cell lung cancer (NSCLC), and has multiple roles in promoting tumor growth and survival. L-BLP25 was being investigated in the Phase III START trial and is currently being investigated in the INSPIRE trial, both for the treatment of unresectable stage III NSCLC
