BOSTON, Nov. 03, 2023 (GLOBE NEWSWIRE) — Elicio Therapeutics, Inc. (Nasdaq: ELTX, “Elicio Therapeutics” or “Elicio”), a clinical-stage biotechnology company developing a pipeline of novel immunotherapies for the treatment of cancer, today announced promising updated preliminary translational data from the ongoing Phase 1 (AMPLIFY-201) study of its lead cancer vaccine candidate, ELI-002, in patients with high relapse risk mKRAS-driven pancreatic and colorectal cancers, and new preclinical data on vaccine candidates, ELI-007 and ELI-008.
The data will be presented at the Society for Immunotherapy of Cancer 38th Annual Meeting (SITC 2023) taking place at the San Diego Convention Center in San Diego, CA and virtually from November 1-5, 2023.
“The data presented here and at the AACR Special Conference on Pancreatic Cancer in September, demonstrate that the T cell-targeted mechanism of action of ELI-002 is induced in high relapse risk patients with pancreatic and colorectal cancers, with the strength of the antigen-specific immune responses induced by ELI-002 correlating with reduced relapse risk. This is an important validation of ELI-002 and the Amphiphile platform, which promise to harness the power of the lymph nodes to generate and activate T cells to target solid tumors,” said Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer.
Pete DeMuth, Ph.D., Chief Scientific Officer, added, “These preclinical data demonstrate ELI-007 and ELI-008 induced strong T cell activation against both mutant p53 and BRAF representing a set of promising therapeutic opportunities for targeting a large fraction of human solid cancers. These data, showing T cell responses >10-500-fold increased over soluble peptide comparators, also suggest the broad applicability of our AMP platform and build on previous data supporting our lymph node-targeting approach for addressing some of the most aggressive cancers.”

Title: Lymph node targeted AMP-peptide vaccines generate functional T cell immunity against mutant p53 and BRAF
Abstract Number: 1145
Presenter: Martin Steinbuck, Ph.D.
ELI-007, a mutant BRAF-peptide vaccine, and ELI-008, a p53 hotspot mutation-peptide vaccine, are being evaluated in studies funded by a grant from the Gastro-Intestinal (GI) Research Foundation with the aim of developing multivalent cancer vaccines targeting several mutations.

About ELI-002
ELI-002 is a structurally novel investigational AMP therapeutic immunotherapy targeting mutant KRAS-driven cancers. KRAS mutations are among the most prevalent human cancers. The seven KRAS driver mutations targeted by the ELI-002 7P formulation are present in 25% of all solid tumors. In particular, 93% of pancreatic ductal adenocarcinoma and 52% of colorectal cancers, those most prevalent in the AMPLIFY-201 study, are positive for KRAS mutations. In addition, 27% of non-small cell lung cancers are positive for KRAS mutations. ELI-002 is comprised of AMP-modified mutant KRAS peptide antigens and ELI-004, an AMP-modified immune-stimulatory oligonucleotide CpG adjuvant. The AMP mKRAS peptides and AMP CpG are targeted to the lymph node where they can potentially enhance the action of key immune cells.
ELI-002 2P is currently being studied in a Phase 1 trial (AMPLIFY-201) in patients with high relapse risk mKRAS-driven solid tumors, following surgery and chemotherapy (NCT04853017). ELI-002 7P, is currently being studied in AMPLIFY-7P, a Phase 1/2 trial in patients with high relapse risk mKRAS-driven solid tumors (NCT05726864). The ELI-002 7P formulation is designed to provide immune response coverage against seven of the most common KRAS mutations, thereby increasing the potential patient population for ELI-002 and potentially reducing the chance of bypass resistance mechanisms.
About the Amphiphile Platform
Our proprietary Amphiphile, or AMP, platform delivers investigational immunotherapeutics directly to the “brain center” of the immune system – the lymph nodes. We believe 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 preclinical models, we have observed lymph node-specific engagement driving therapeutic immune responses of increased magnitude, function, and durability. We believe our AMP lymph node-targeted approach will produce superior clinical benefits compared to immunotherapies that do not engage the lymph nodes based upon preclinical studies.
Our 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 Amphiphile platform has been shown to deliver immunotherapeutics directly to the lymph nodes by latching on to the protein albumin, found in the bloodstream, as it travels to lymphatic tissue. In preclinical models, we have observed lymph node-specific engagement driving immune responses of increased magnitude, function, and durability.
