• ELI-002 7P demonstrated robust mKRAS-specific T cell responses across a broad range of HLA types, highlighting its potential for use among a diverse patient population
• Patients treated with ELI-002 7P represented a diverse HLA repertoire including 1,132 unique types identified among 1,398 total HLA backgrounds in assessed patients
• 99% (88/89) of patients assessed for HLA background induced mKRAS-specific T cell responses after treatment with ELI-002 7P
• Induction of mKRAS-specific T cell responses suggest that ELI-002 7P may address a broad patient population with high unmet need for pancreatic ductal adenocarcinoma (“PDAC”)

BOSTON, Oct. 27, 2025 (GLOBE NEWSWIRE) -- Elicio Therapeutics, Inc. (Nasdaq: ELTX, “Elicio” or the “Company”), a clinical-stage biotechnology company developing a pipeline of novel immunotherapies for the treatment of cancer, today announced that preliminary analysis of patients in the ongoing Phase 2 AMPLIFY-7P trial indicated that specific Human Leukocyte Antigen (“HLA”) types (alleles) were not associated with a patient’s ability to elicit robust mKRAS-specific T-cell response following treatment with ELI-002 7P. 

Among 89 patients treated with ELI-002 7P, a total of 1,132 unique HLAs were represented across the primary class I and class II variants, highlighting substantial genetic diversity within the study population. These findings are consistent with a growing body of evidence indicating that mKRAS antigens can be presented across a broad range of HLA types. Elicio’s data is consistent with recent analysis published in Cell Reports Methods that found T cells specific to mKRAS G12D and/or G12V in 20/20 (100%) healthy donors evaluated across a diverse HLA background, suggesting that the majority of patients possess mKRAS-presenting HLAs and include mKRAS-specific T cell responses within their immune repertoire.

Robert Connelly, Chief Executive Officer of Elicio, commented, “We are extremely pleased to see that mKRAS-specific T cell responses are induced among patients with a diverse HLA background, suggesting that ELI-002 7P may be applicable to a broad range of PDAC patients potentially addressing a key unmet need and expanding the potential market opportunity. Our observations build on past data to show that the majority of patients express mKRAS-presenting HLAs, likely enabling T cell recognition in most patients. These encouraging findings highlight the potential for ELI-002 7P to benefit a broader spectrum of PDAC patients, which may extend the reach of immunotherapy to more individuals and address a critical unmet need.”

About Elicio Therapeutics

Elicio Therapeutics, Inc. (Nasdaq: ELTX) is a clinical-stage biotechnology company advancing novel immunotherapies for the treatment of high-prevalence cancers, including mKRAS-positive pancreatic and colorectal cancers. Elicio intends to build on recent clinical successes in the personalized cancer immunotherapy space to develop effective, off-the-shelf immunotherapies. Elicio’s Amphiphile (“AMP”) technology aims to enhance the education, activation and amplification of cancer-specific T cells relative to conventional immunotherapy strategies, with the goal of promoting durable cancer immunosurveillance in patients. Elicio’s ELI-002 lead program is an off-the-shelf immunotherapy candidate targeting the most common KRAS mutations, which drives approximately 25% of all solid tumors. Off-the-shelf immunotherapy approaches have the potential benefits of low cost, rapid commercial scale manufacturing, and rapid availability of drug to patients especially in neo-adjuvant settings and for prophylaxis in high-risk patients, contrary to personalized immunotherapy approaches. ELI-002 is being studied in an ongoing, randomized clinical trial in patients with mKRAS-positive pancreatic cancer who completed standard therapy but remain at high risk of relapse. ELI-002 also has been studied in patients with mKRAS-positive colorectal cancer (“CRC”) in Phase 1 studies. The updated AMPLIFY-201 Phase 1 data for PDAC and CRC was presented at the ESMO Immuno-Oncology Congress 2024 and included a 16.3-month median recurrence-free survival and 28.9-month median overall survival for the full study population. In the future, Elicio plans to expand ELI-002 to other indications including mKRAS positive lung cancer and other mKRAS positive cancers. Elicio’s pipeline includes additional off-the-shelf therapeutic cancer immunotherapy candidates, including ELI-007 and ELI-008, that target BRAF-driven cancers and p53 hotspot mutations, respectively.

About ELI-002

Elicio’s lead product candidate, ELI-002, is a structurally novel investigational AMP cancer immunotherapy that targets cancers that are driven by mutations in the KRAS-gene—a prevalent driver of many human cancers. ELI-002 is comprised of two powerful components that are built with Elicio’s AMP technology consisting of AMP-modified mutant KRAS peptide antigens and ELI-004, an AMP-modified CpG oligodeoxynucleotide adjuvant that is available as an off-the-shelf subcutaneous administration.

ELI-002 2P (2-peptide formulation) has been studied in the Phase 1 (AMPLIFY-201) trial in patients with high relapse risk mKRAS-driven solid tumors, following surgery and chemotherapy (NCT04853017). ELI-002 7P (7-peptide formulation) is currently being studied in a Phase 1/2 (AMPLIFY-7P) trial in patients with mKRAS-driven pancreatic cancer (NCT05726864). The ELI-002 7P formulation is designed to provide immune response coverage against seven of the most common KRAS mutations present in 25% of all solid tumors, thereby increasing the potential patient population for ELI-002.

About the Amphiphile Platform

Elicio’s proprietary AMP platform delivers investigational immunotherapeutics directly to the “brain center” of the immune system – the lymph nodes. Elicio believes this site-specific delivery of disease-specific antigens, adjuvants and other immunomodulators may efficiently educate, activate and amplify critical immune cells, potentially resulting in induction and persistence of potent adaptive immunity required to treat many diseases. In pre-clinical models, Elicio observed lymph node-specific engagement driving therapeutic immune responses of increased magnitude, function and durability. Elicio believes its AMP lymph node-targeted approach will produce superior clinical benefits compared to immunotherapies that do not engage the lymph nodes based on preclinical studies.

Elicio’s AMP platform, originally developed at the Massachusetts Institute of Technology, has broad potential in the cancer space to advance a number of development initiatives through internal activities, in-licensing arrangements or development collaborations and partnerships.

The AMP platform has been shown to deliver immunotherapeutics directly to the lymph nodes by latching on to the protein albumin, found in the local injection site, as it travels to lymphatic tissue.
