SYDNEY, AUSTRALIA, Oct. 16, 2023 -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep” or “the Company”), a clinical-stage biotechnology company developing novel LAG-3 immunotherapies for cancer and autoimmune disease, today announces the publication of abstracts with data from the TACTI-002 and INSIGHT-003 trials in 1st line non-small cell lung cancer (1L NSCLC) at the 2023 European Society for Medical Oncology (ESMO) Congress.
TACTI-002 is a Phase II trial evaluating the chemotherapy-free combination of eftilagimod alpha (“efti”) and KEYTRUDA® (pembrolizumab), MSD’s (Merck & Co., Rahway, NJ, USA) anti-PD-1 therapy, in 1L NSCLC. The TACTI-002 abstract published by ESMO, which contains data based on a cut-off date of 31 March 2023, showed an excellent initial survival benefit across an all-comer PD-L1 patient population in 1L NSCLC as well as for patients in each PD-L1 Tumour Proportion Score (TPS) subgroup, including 38.8 months in TPS >50%, 23.4 months in TPS 1-49%, and 25.0 months in TPS >1% (the OS result in TPS >1%, a key area of focus for future development where efti has FDA Fast Track designation, was already reported on May 17, 2023).
Notably, new updated data from TACTI-002, including more mature Overall Survival (OS) results, will be presented by Dr. Enric Carcereny, Catalan Institute of Oncology, Badalona (ICO), during a Mini Oral session (#1312MO) at ESMO Congress 2023 on Saturday, October 21, 2023, at 9:05 AM CEST.
INSIGHT-003 is an investigator-initiated Phase I trial conducted by the Frankfurt Institute of Clinical Cancer Research IKF evaluating efti in conjunction with KEYTRUDA® and doublet chemotherapy in non-squamous 1L NSCLC patients. The data in the INSIGHT-003 abstract, with a cut-off date of 18 April 2023, showed a promising 67% overall response rate. Additionally, a Trials in Progress (TiP) abstract on the EFTISARC-NEO trial evaluating efti in combination with radiotherapy and KEYTRUDA® titled has been published.
Abstracts are available on the ESMO website, and the mini oral presentation & posters will be available on Immutep’s website following their presentation.

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).
Immutep is a clinical-stage biotechnology company developing novel LAG-3 immunotherapy for cancer and autoimmune disease. We are pioneers in the understanding and advancement of therapeutics related to Lymphocyte Activation Gene-3 (LAG-3), and our diversified product portfolio harnesses its unique 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
