Elicio Therapeutics Announces Positive Interim Data from the Phase 1 Study of an Investigational Therapeutic Cancer Immunotherapy, ELI-002, in Patients with High Relapse Risk Pancreatic and Colorectal Cancer at the ASCO Annual Meeting
BOSTON, June 03, 2023 (GLOBE NEWSWIRE) -- Elicio Therapeutics (Nasdaq: ELTX), a clinical-stage biotechnology company developing a pipeline of novel immunotherapies for the treatment of cancer, today announced positive interim clinical data from the ongoing Phase 1 (AMPLIFY-201) study of its lead asset, ELI-002, an investigational therapeutic cancer immunotherapy. This study evaluated ELI-002 2P, a 2-peptide formulation designed to treat cancers driven by G12D and G12R mutations in KRAS. ELI-002 was studied as a monotherapy in patients with mutant KRAS-driven tumors who are at high risk for relapse due to detection of minimal residual disease (MRD) following standard surgery and chemotherapy (NCT04853017). The data will be presented in a poster discussion session at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, a hybrid event taking place online and at McCormick Place in Chicago from June 2-6, 2023.
ELI-002 2P was well-tolerated, with no dose limiting toxicity or cytokine release syndrome across 5 cohorts that evaluated ascending doses from 0.1 to 10.0 mg of the adjuvant Amph-CpG. Responses were observed at all dose levels, with a high proportion of patients having tumor biomarker reduction including a subset with clearance. Robust mKRAS-specific T cell responses were induced in 87% of patients with an average of a 56-fold [range 2-423-fold] increase directly ex vivo.
“mKRAS-specific T cells have been shown to mediate anti-tumor efficacy, which prompted us to assess ELI-002 in high relapse-risk patients where tumor biomarkers can provide an early efficacy signal,” said Eileen M. O’Reilly, M.D., Winthrop Rockefeller Endowed Chair of Medical Oncology; Co-Director, Medical Initiatives, David M. Rubenstein Center for Pancreatic Cancer Research; Section Head, Hepatopancreaticobilary & Neuroendocrine Cancers, Memorial Sloan Kettering Cancer Center (MSK). “We are encouraged by the findings which showed that ELI-002 was well-tolerated. The trial enabled patients to enroll with minimal disease which reduces the chances of an immunosuppressive tumor environment and increases the ratio of T cells to target tumor cells.”
Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer, said, “ELI-002 is designed with our proprietary AMP technology, which allows for smart delivery to the lymph nodes, the ‘brain center’ of the immune system. The immune responses observed were robust and durable in addition to being able to carry out multiple anti-tumor functions. These data validate the clinical activity of ELI-002 with two peptides and support our bridge to the 7-peptide formulation of ELI-002, designed to stimulate an immune response against the seven most common KRAS mutations present in 25% of solid cancer patients. We are grateful to the patients, caregivers, physicians and study staff for their contribution to this study.”
Title: AMPLIFY-201, a first-in-human safety and efficacy trial of adjuvant ELI-002 2P immunotherapy for patients with high-relapse risk with KRAS G12D- or G12R-mutated pancreatic and colorectal cancer.
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. A new formulation, 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. 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, or MIT, 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.
About Elicio Therapeutics
Elicio Therapeutics is a clinical-stage biotechnology company developing a pipeline of novel immunotherapies for the treatment of cancer. By combining expertise in immunology and immunotherapy, Elicio is engineering investigational Amphiphile (AMP) immunotherapies intended to precisely target and fully engage the lymph nodes, the site in our bodies where the immune response is orchestrated. Elicio is engineering lymph node-targeted AMPlifiers, immunomodulators, adjuvants and vaccines for an array of aggressive cancers.
Elicio began dosing subjects in AMPLIFY-201, its Phase 1 clinical trial in solid tumor subjects for its lead AMP immunotherapy, ELI-002 2P, targeting mKRAS-driven cancers, in October 2021 and began dosing subjects with the new formulation, ELI-002 7P, in April 2023. The AMP platform emerged from the laboratories of Darrell Irvine, Howard Hughes Investigator and Professor of Biomedical Engineering in the Koch Institute of Integrative Cancer Research at MIT.
