Immutep Announces Abstract Accepted for Presentation at the American Society of Clinical Oncology (ASCO) 2026 Annual Meeting
SYDNEY, AUSTRALIA, April 22, 2026 (GLOBE NEWSWIRE) -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or “the Company”), a clinical-stage immunotherapy company targeting cancer and autoimmune diseases, today announces an abstract has been selected for poster presentation at the upcoming 2026 American Society of Clinical Oncology’s (ASCO) Annual Meeting, taking place in-person and online from 29 May-2 June 2026 in Chicago, Illinois (United States).
The accepted abstract, titled “Impact of eftilagimod alfa, an APC activator via MHC class II, on lymphocyte activation and survival outcomes in metastatic cancer patients,” will be presented within the Developmental Therapeutics—Immunotherapy sessions by Professor Martin Forster from the UCL Cancer Institute, UK.
The poster will present cumulative clinical and translational data demonstrating that eftilagimod alfa (efti), an antigen-presenting cell (APC) activator targeting MHC Class II, induces rapid and sustained lymphocyte activation. Across multiple late-stage cancer studies1, immune activation markers were associated with improved overall survival outcomes in patients with metastatic disease, supporting the clinical relevance of eftilagimod alfa’s mechanism of action.
