About IMMUTEP LIMITED

https://www.immutep.com

Immutep Limited focuses on the development of novel immunotherapy treatments for cancer and autoimmune diseases, specifically targeting the Lymphocyte Activation Gene-3 (LAG-3) pathway. The company's lead therapeutic candidate is eftilagimod alpha (efti), a first-in-class soluble LAG-3 protein and MHC class II agonist. Efti functions by activating antigen-presenting cells, which in turn triggers a robust T cell response against tumors. It is currently being evaluated in clinical trials for multiple solid tumor indications, including non-small cell lung cancer and head and neck squamous cell carcinoma, frequently in combination with other anti-cancer agents. The pipeline also includes IMP761, an agonist antibody designed to suppress overactive immune responses in autoimmune conditions. The company's technology utilizes the LAG-3 protein's role in immune regulation to create targeted therapeutic interventions.
