Exhibit 99.1


Nature Medicine Publishes Updated Preliminary Phase 1 Data From Elicio Therapeutic’s AMPLIFY-201 Phase 1 Solid Tumor Study of ELI-002


●
Data showed ELI-002 administered as a monotherapy induced robust, polyfunctional and durable KRAS specific CD4+ and CD8+ T cell responses

●
Tumor biomarker reduction was observed in 84% of patients correlating with a median relapse-free survival of 16.3 months

●
Phase 2 trial of ELI-002 monotherapy in pancreatic ductal adenocarcinoma (“PDAC”) planned to initiate in early 2024

BOSTON, January 9, 2024 – 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 the publication of data from the Phase 1 (AMPLIFY-201) study of ELI-002 2P in Nature Medicine.  The paper, “Lymph Node Targeted, mKRAS-specific Amphiphile Vaccine in Pancreatic and Colorectal Cancer: The phase 1 AMPLIFY-201 Trial”, details expanded and updated results originally presented at the 2023 American Society of Clinical Oncology (“ASCO”) Annual Meeting and the 2023 AACR Special Conference on Pancreatic Cancer.

“When tumor DNA or protein persists or recurs after treatment, patients with pancreatic and colorectal cancers are unfortunately not left with many options and are often incurable,” said study author Shubham Pant, M.D., Associate Professor of Gastrointestinal Medical Oncology at The University of Texas MD Anderson Cancer Center. “These are promising early findings from the AMPLIFY-201 study with follow up ongoing.  Most patients reduced their tumor biomarkers with some having complete clearance following treatment with ELI-002.”

Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer, added, “Our lymph node-targeted cancer vaccine candidate induced direct ex vivo mKRAS-specific T cell responses in 84% of patients, with 59% of patients demonstrating a response with two key types of T cells – helper cells and killer cells. Past studies have not seen this large a fraction of patients respond, this high a magnitude of a response or the expansion of both key populations of T cells. Importantly, these T cell responses were specific to tumor-driver mutant KRAS neoantigens, correlated with reduced risk of relapse and we saw a pool of memory T cells form that we believe hold promise to confer long-term protection.  We look forward to progressing ELI-002 into a randomized phase 2 trial as a monotherapy for patients with PDAC.”

Nature Medicine Publication Highlights


 ●
The data is as of September 6, 2023, based on 25 patients with solid tumors (20 pancreatic, 5 colorectal) who were positive for minimal residual mKRAS disease after locoregional treatment.

●
Direct ex vivo mKRAS-specific T cell responses were observed in 21/25 patients (84%; 59% both CD4+ and CD8+).

●
Tumor biomarker responses were observed in 21/25 patients (84%) and biomarker clearance in 6/25 patients, as determined by tumor-informed circulating tumor DNA (24%; 3 pancreatic, 3 colorectal).

●
At 8.5 months median follow-up the median RFS of the 25-patient cohort was 16.33 months.

●
Efficacy correlated with T cell response (≥ versus < median: 12.75-fold over baseline):

o
Median tumor biomarker reduction was -76.0% compared to -10.2% in above versus below median T cell responders, respectively (p<0.0014).

o
Median RFS was not reached compared to 4.01 months in above versus below median T cell responders, respectively (HR 0.14, 95% CI 0.03 to 0.63, p=0.0167).

o
Patients with greater than median T cell response had an 86% reduction in the risk of progression or death.

●
The association of RFS with T cell response was not correlated to baseline prognostic variables including tumor stage, recovery from prior cytotoxic therapy as assessed by absolute neutrophil count or immune system subsets such as %CD4+ or %CD8+ of CD3+ lymphocytes.

●
RFS was shorter in patients who began treatment with a low absolute lymphocyte count.

●
No safety concerns were identified, and no dose limiting toxicities and no ≥ grade 3 treatment related adverse events were observed.

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 available as an off-the-shelf subcutaneous administration. 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 Elicio Therapeutics
