The expiry date of the patent is 20 January 2036.<\/p>\n<p align=\"justify\">This grant further expands Immutep\u2019s intellectual property protection for eftilagimod alfa in combination with PD-1 pathway inhibitors, a key class of immunotherapies used in modern cancer treatment.<\/p>\n<p align=\"justify\">\n        <b>Marc Voigt, CEO of Immutep, said:<\/b> \u201cWe are very pleased to add this fourth United States patent to our expanding patent portfolio covering eftilagimod alfa in combination with PD-1 pathway inhibitors. This represents a meaningful addition to our intellectual property estate. As we consider next steps for efti, this expanded IP estate supports future development pathways and business development opportunities.\u201d<\/p>\n<p align=\"justify\">\n        <b>About Eftilagimod Alfa (Efti)<\/b><br \/>\n        <br \/>Efti is a novel immunotherapy that directly activates antigen-presenting cells or APCs (e.g. dendritic cells, monocytes) via the MHC Class II pathway to fight cancer. As an MHC Class II agonist, its activation of APCs engages the adaptive and innate immune system to initiate a broad anti-cancer immune response. This includes priming and activating cytotoxic T cells as well as generating important co-stimulatory signals and cytokines that further boost the immune system\u2019s ability to combat cancer.<\/p>\n<p align=\"justify\">Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), soft tissue sarcoma, and breast cancer. Its favourable safety profile enables various combinations including with anti-PD-[L]1 immunotherapy, radiotherapy, and\/or chemotherapy. Efti has received Fast Track designation in 1st line HNSCC and in 1st line NSCLC from the United States Food and Drug Administration (FDA).<\/p>\n<p align=\"justify\">\n        <b>About Immutep<\/b><br \/>\n        <br \/>Immutep is a clinical-stage biotechnology company developing novel immunotherapies for cancer and autoimmune diseases.
