Eftilagimod alpha

Aug. 05, 2025 -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or “the Company”), a late-stage immunotherapy company targeting cancer and autoimmune diseases, today announces it has received positive and constructive feedback from the US Food and Drug Administration (FDA), regarding future clinical development of its first-in-class MHC Class II agonist, eftilagimod alfa (“efti”), for first line treatment of recurrent/metastatic head and neck squamous cell carcinoma (1L HNSCC) patients who have PD-L1 expression below 1 (Combined Positive Score [CPS] Based on its review of the encouraging data in 1L HNSCC with CPS ® (pembrolizumab), the FDA agreed on the potential of efti in combination with KEYTRUDA to address the high unmet need in this CPS Paths for future clinical development and potential accelerated approval in light of the FDA’s Project FrontRunner include a randomised registrational trial evaluating efti in combination with KEYTRUDA against standard-of-care therapy or alternatively a smaller single-arm study (e.g. 70 - 90 patients) with safety, response rate, and duration of response as key endpoints, followed by a confirmatory randomised study that builds on the existing data. “We are pleased with the FDA’s feedback and guidance that underscores the high unmet need of head and neck cancer patients whose PD-L1 expression level is below one. The FDA feedback positions Immutep to evaluate options for future collaborative clinical development paths to bring a new, effective and safe treatment option to this underserved patient population,” said Marc Voigt, CEO of Immutep. “Our primary focus clearly remains the pivotal TACTI-004 Phase III evaluating efti as first line therapy for non-small cell lung cancer and we are excited with its progress to date and the consistent, encouraging feedback we hear from physicians. This focus and additional considerations will be reviewed internally and discussed with stakeholders and potential strategic partners in regards to forward paths in head and neck cancer,” added Mr Voigt. Project FrontRunner is an FDA Oncology Center of Excellence (OCE) initiative to encourage drug sponsors to consider when it may be appropriate to develop and seek approval of cancer drugs for advanced/metastatic disease, in an earlier clinical setting rather than the usual approach to develop and seek approval of a drug for treatment of patients who have received numerous prior lines of therapies or have exhausted available treatment options. In this setting, advancing new effective therapies has the greatest potential to significantly improve quantity and quality of patients’ lives. Patients with CPS <1 in 1L HNSCC represent a treatment population with high unmet medical need. Up to 20% of 1L HNSCC patients have CPS <1 and despite immunotherapy’s progress in fighting cancer, anti-PD-1 therapy alone (without chemotherapy) is only approved for patients who express PD-L1 (CPS >1). All currently available treatment options for patients with PD-L1 CPS <1 include chemotherapy. Immutep is a late-stage biotechnology company developing novel immunotherapies for cancer and autoimmune disease. The Company is a pioneer in the understanding and advancement of therapeutics related to Lymphocyte Activation Gene-3 (LAG-3), and its diversified product portfolio harnesses LAG-3’s ability to stimulate or suppress the immune response. Immutep is dedicated to leveraging its expertise to bring innovative treatment options to patients in need and to maximise value for shareholders. For more information, please visit www.immutep.com.

SYDNEY, AUSTRALIA, July 29, 2025 (GLOBE NEWSWIRE) -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or “the Company”), a late-stage immunotherapy company targeting cancer and autoimmune diseases, today announces an upcoming poster presentation for the pivotal TACTI-004 (KEYNOTE-F91) Phase III trial at the IASLC 2025 World Conference on Lung Cancer (WCLC), taking place in Barcelona, Spain, from 6-9 September 2025. The Trial in Progress poster includes an overview and study design of the TACTI-004 Phase III evaluating the Company’s antigen presenting cell (APC) activator, eftilagimod alfa (efti) in combination with MSD’s (Merck & Co., Inc., Rahway, NJ, USA) anti-PD-1 KEYTRUDA® (pembrolizumab) and chemotherapy as first line therapy for patients with advanced or metastatic non-small cell lung cancer (1L NSCLC). The global trial will enrol approximately 750 patients regardless of PD-L1 expression (Tumour Proportion Score or TPS of 0-100%) and with non-squamous or squamous tumours at over 150 clinical sites in over 25 countries. Immutep CMO, Stephan Winckels M.D., Ph.D, said, “Our engagement to date with physicians in the lung cancer community, including at ELCC in Paris and ASCO in Chicago, has yielded encouraging feedback with a shared view of efti as a safe, easy-to-administer immunotherapy with strong efficacy across two 1L NSCLC trials. We look forward to continuing our investigator discussions at WCLC and ESMO around the pivotal TACTI-004 Phase III, which has the potential to change the treatment paradigm for patients with advanced or metastatic non-small cell lung cancer, irrespective of their PD-L1 expression.” Details for the poster presentation:Title: TACTI-004, a Phase 3 trial of Eftilagimod Alfa plus Pembrolizumab (P) + Chemotherapy (C) vs Placebo + P + C in 1st line NSCLC Presenter: Dr. Martin Sebastian, University Hospital of Frankfurt, GermanySession: Clinical Trials in ProgressDate and Time: Tuesday, 9 September 2025 at 10:00 AM CEST The poster will be available on the Posters & Publications section of Immutep’s website following the presentation. About Eftilagimod Alfa (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 first line HNSCC and in first line NSCLC from the United States Food and Drug Administration (FDA).
