Additionally, data from INSIGHT-003, an investigator-initiated Phase I trial conducted by the Frankfurt Institute of Clinical Cancer Research IKF evaluating efti in conjunction with anti-PD-1 therapy (pembrolizumab) and doublet chemotherapy (carboplatin/pemetrexed) in non-squamous 1L NSCLC, has been accepted for a poster presentation. Also, a Trial in Progress poster for the EFTISARC-NEO investigator-initiated Phase II trial evaluating efti with pembrolizumab and radiotherapy in soft tissue sarcoma will be presented.

About Eftilagimod Alpha (Efti)
Efti is Immutep’s proprietary soluble LAG-3 protein and MHC Class II agonist that stimulates both innate and adaptive immunity for the treatment of cancer. As a first-in-class antigen presenting cell (APC) activator, efti binds to MHC (major histocompatibility complex) Class II molecules on APC leading to activation and proliferation of CD8+ cytotoxic T cells, CD4+ helper T cells, dendritic cells, NK cells, and monocytes. It also upregulates the expression of key biological molecules like IFN-ƴ and CXCL10 that further boost the immune system’s ability to fight cancer.
Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and metastatic breast cancer. Its favourable safety profile enables various combinations, including with anti-PD-[L]1 immunotherapy 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).
