Elicio Therapeutics Announces Preliminary Data from the Ongoing AMPLIFY-7P Phase 1a Study of ELI-002 7P in Patients with mKRAS-driven Solid Tumors at the 2024 ASCO Annual Meeting
Elicio Therapeutics revealed preliminary data from their AMPLIFY-7P Phase 1a study of ELI-002 7P at the ASCO 2024 Annual Meeting. The cancer vaccine candidate, targeting mKRAS-driven solid tumors, showed promising results. ELI-002 7P was well tolerated and induced a significant (~100x) mKRAS-specific T cell response in all enrolled patients.
Key findings included CD8+ and CD4+ responses in 66.7% of patients at the 4.9 mg dose, and tumor biomarker reductions in 71% of evaluable patients. Antigen-spreading, targeting non-immunizing tumor neoantigens, was observed in all patients at the 4.9 mg dose. The study supports further development, with the recommended Phase 2 dose being 10.0 mg AMP-CpG-7909 with 4.9 mg AMP-Peptides 7P.
- ELI-002 7P induced a 100x mKRAS-specific T cell response.
- All patients showed mKRAS-specific T cell responses.
- 66.7% of patients had both CD8+ and CD4+ responses at the 4.9 mg dose.
- 71% of evaluable patients showed tumor biomarker reductions at the 4.9 mg dose.
- Antigen-spreading was observed in all patients at the 4.9 mg dose.
- No dose-limiting toxicities or treatment-related serious adverse events were reported.
- The data presented is preliminary, necessitating further validation in Phase 2 trials.
- Only 5 out of 7 evaluable patients showed tumor biomarker reductions, indicating variability in response.
- Minimum residual disease clearance was observed in only one patient.
- Observations are to the 4.9 mg dose, requiring additional data for other dosages.
Insights
The preliminary data from Elicio Therapeutics' AMPLIFY-7P Phase 1a study shows promising early results for ELI-002 7P, a cancer vaccine targeting mKRAS-driven tumors. The study reports high levels of T cell engagement and tumor biomarker reductions. Specifically, the vaccine generated a robust T cell response in
This is significant because KRAS mutations are notoriously difficult to target and current treatments often fail due to resistance mechanisms. The ability of ELI-002 7P to target multiple KRAS mutations and induce polyfunctional T cell responses can potentially address this challenge. However, these are early-stage results and further data from the Phase 2 trials will be critical in confirming its efficacy and safety.
ELI-002 7P appears to be a well-tolerated vaccine capable of generating significant T cell responses. This is especially important for patients with KRAS mutations, which are common in various solid tumors like pancreatic and colorectal cancers. The vaccine’s ability to induce responses in both CD8+ and CD4+ T cells at the recommended Phase 2 dose is noteworthy. These cells are essential for a coordinated immune attack on tumors, which might explain the observed tumor biomarker reductions.
For patients with minimal residual disease, this could mean longer remission periods and improved survival rates. The absence of serious adverse events and dose-limiting toxicities adds to the potential for this vaccine to be a game-changer in oncology. Yet, more extensive studies are needed to validate these findings.
From an investment perspective, Elicio Therapeutics' preliminary data presents a cautiously optimistic outlook. Investors should be encouraged by the vaccine’s early efficacy and safety profile, as well as the potential for broad application across multiple KRAS mutations. The mention of significant T cell response and tumor biomarker reductions in a high percentage of patients could drive investor confidence and potentially impact stock prices favorably.
However, it's important to note that these results are preliminary. Investors should closely follow subsequent trial phases and regulatory milestones. The biotech market is inherently volatile and the success of ELI-002 7P will hinge on further validation in larger, more diverse patient populations.

BOSTON, May 23, 2024 (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 preliminary data from the ongoing AMPLIFY-7P Phase 1a study of its off-the-shelf investigational therapeutic cancer vaccine candidate, ELI-002 7P, in a poster presentation at the American Society of Clinical Oncology (“ASCO”) Annual Meeting, being held May 31-June 4, 2024, in Chicago, IL. The preliminary data showed ELI-002 7P was well tolerated with T cell responses correlating with a reduction in tumor biomarkers at the recommended Phase 2 dose (“RP2D”).
The AMPLIFY-7P study is evaluating the 7-peptide formulation of Elicio’s cancer vaccine candidate, ELI-002 7P, in patients with mKRAS-driven solid tumors that are positive for minimal residual disease following standard locoregional treatment. ELI-002 7P was developed with Elicio’s proprietary lymph node-targeting Amphiphile (“AMP”) technology designed to stimulate an immune response against the seven KRAS mutations (G12D, G12R, G12V, G12A, G12C, G12S and G13D) that drive
“KRAS mutated cancers are difficult to target in part due to the number of diverse mutations and bypass resistance mechanisms. We are encouraged by the first data from the ongoing AMPLIFY-7P trial, which demonstrate ELI-002 7P has a favorable safety profile and early antitumor effects that correlate with induction of T cells specific for multiple KRAS mutations potentially providing broader coverage for patients,” said Craig E. Devoe, M.D., MHCM., Chief, Division of Medical Oncology & Hematology, R.J. Zuckerberg Cancer Center, and Scientific Investigator, Northwell Health.
Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer, added, “These early immunogenicity and biomarker response data from ELI-002 7P continue to provide encouraging results showing that our lymph node-targeted approach generates a robust and differentiated T cell response that strongly correlates with tumor biomarker reductions. Across two trials, ELI-002 has demonstrated an ability to generate a robust T cell response against all mKRAS mutations of enrolled patients as well as T cell responses against non-immunizing personalized tumor neoantigens. ELI-002’s broader KRAS mutation coverage and higher T cell responses with the 7-peptide vaccine at the Phase 2 dose holds promise for the high unmet need of patients with KRAS-mutated tumors.”
