Elicio Therapeutics Reports Third Quarter 2025 Financial Results and Provides Corporate Updates  In the ongoing Phase 2 AMPLIFY-7P study evaluating ELI-002 7P in patients with pancreatic ductal adenocarcinoma (“PDAC”), fewer disease progressions and deaths than projected have been observed as of November 6, 2025.  Based on 2:1 randomization with twice as many patients in the ELI-002 7P treatment arm compared to the observation arm, Elicio believes the lower-than-projected number of disease progressions and deaths may reflect a favorable impact on disease-free survival (“DFS”); event-driven primary DFS analysis now anticipated in 1H 2026.  Since the beginning of Q3 2025, the Company has raised gross proceeds of approximately $11.1 million through its established at-the-market program, extending Elicio’s cash runway through Q2 2026.  Current cash position is expected to support operations beyond the anticipated Phase 2 AMPLIFY-7P event-driven primary DFS endpoint analysis anticipated in 1H 2026.  The Company remains blinded to the Phase 2 AMPLIFY-7P trial clinical eƯicacy outcomes. BOSTON, November 13, 2025 — 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 reported financial results for the third quarter ended September 30, 2025, and provided recent corporate and clinical updates. “We are encouraged to see fewer disease progressions and deaths in the Phase 2 AMPLIFY- 7P study than originally projected in our statistical modeling. This may reflect a favorable impact on DFS. Because the DFS analysis is event-driven and triggered by a predefined number of events, we are updating our guidance for the timing of the event-driven primary DFS endpoint analysis to the first half of 2026. Importantly, we believe our current cash position will allow us to reach this critical catalyst and beyond as we continue advancing ELI-002 7P toward its potential to meaningfully improve outcomes for patients with KRAS- mutant pancreatic cancer,” said Robert Connelly, Chief Executive OƯicer of Elicio. Recent Highlights

 In November 2025, Elicio presented updated Phase 2 AMPLIFY-7P data at the Society for Immunotherapy of Cancer’s Annual Meeting, showing that ELI-002 7P induced mutant KRAS (“mKRAS”)-specific T cell responses in 99% (89/90) of evaluable patients with an 86% antigen response rate. In addition, Elicio reported 86.8% (66/76) of evaluable patients induced cytotoxic mKRAS-specific T cell responses; 75% (57/76) induced CD8+ T cells and 75% (57/76) induced CD4+ T cells. Responses were observed across all seven mKRAS epitopes and occurred across a diverse HLA background, highlighting ELI-002 7P’s potential to benefit a broad and genetically diverse patient population.  In October 2025, Elicio announced robust T cell responses across diverse HLA backgrounds in the ongoing Phase 2 AMPLIFY-7P trial.  In September 2025, Elicio announced the planned investigator-initiated Phase 1 neoadjuvant trial of ELI-002 7P in resectable and borderline resectable PDAC led by Memorial Sloan Kettering Cancer Center and funded by the Lustgarten Foundation, assessing ELI-002 7P combined with mFOLFIRINOX with or without the anti-PD-1 antibody. The trial is designed to enroll 20 patients across two arms and is anticipated to begin in 1H 2026.  In August 2025, Elicio announced the positive recommendation by the Independent Data Monitoring Committee (“IDMC”) to continue the ELI-002 7P randomized Phase 2 study in PDAC without modifications to the final analysis. In addition, the IDMC confirmed the favorable safety profile of ELI-002 7P as of such date; the Company viewed the IDMC’s positive recommendation as an indication that ELI-002 7P has shown preliminary signals of eƯicacy. Upcoming Anticipated Milestones for the Phase 2 AMPLIFY-7P Trial  Upon reaching the event-driven primary DFS endpoint analysis, Elicio will request an End of Phase 2 meeting with the U.S. Food and Drug Administration (“FDA”) to finalize the Phase 3 trial design for ELI-002 7P. Alignment on key elements of the Phase 3 study design was reached with the FDA at the End of Phase 1 meeting announced in Q1 2025. Third Quarter 2025 Financial Results R&D expense for the third quarter of 2025 was $5.0 million, compared to $7.2 million for the third quarter of 2024. The decrease of $2.2 million was primarily due to less clinical trial costs as patients progressed through the Phase 2 AMPLIFY-7P trial.

G&A expense for the third quarter of 2025 was $3.0 million, compared to $3.1 million for the third quarter of 2024. The decrease of $0.1 million was primarily due to lower fees incurred in connection with general corporate matters. Net loss for the third quarter of 2025 was $10.1 million, compared to $18.8 million for the third quarter of 2024. Net loss for the third quarter of 2025 includes $2.0 million in other expense. Net loss per share for the third quarter of 2025 was $0.60 compared to $1.39 for the third quarter of 2024. Cash and cash equivalents as of September 30, 2025 were $20.6 million. The Company expects that its current cash and cash equivalents will support operations through Q2 2026, beyond the anticipated Phase 2 AMPLIFY-7P event-driven primary DFS endpoint analysis anticipated in 1H 2026. 2025 2024 Operating expenses: Research and development $ 5,039 $ 7,208 General and administrative 3,006 3,136 Total operating expenses 8,045 10,344 Loss from operations (8,045) (10,344) Total other (expense) income, net (2,038) (8,494) Net loss (10,083) (18,838) Other comprehensive gain (loss): Foreign currency translation adjustment 39 36 Comprehensive loss $ (10,044) $ (18,802) Net loss per common share, basic and diluted $ (0.60) $ (1.39) Weighted average common shares and pre-funded warrants outstanding, basic and diluted 16,692,476 13,582,345 Condensed Consolidated Statements of Operations and Comprehensive Loss (in thousands, except share and per share amounts) (unaudited) Three Months Ended September 30,

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 eƯective, oƯ-the-shelf immunotherapies. Elicio’s Amphiphile (“AMP”) technology aims to enhance the education, activation and amplification of cancer-specific T cells relative to conventional immunization strategies, with the goal of promoting durable cancer immunosurveillance in patients. Elicio’s ELI-002 lead program is an oƯ-the-shelf immunotherapy candidate targeting the most common KRAS mutations, which drive approximately 25% of all solid tumors. OƯ-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 September 30, 2025 December 31, 2024 Assets Cash and cash equivalents 20,611$ 17,618$ Other current assets 854 3,075 Total current assets 21,465 20,693 Other assets 6,819 7,485 Total assets 28,284$ 28,178$ Liabilities and stockholders' (deficit) equity Current liabilities 6,515$ 11,523$ Long-term liabilities 17,953 27,967 Total liabilities 24,468 39,490 Total stockholders' (deficit) equity 3,816 (11,312) Total liabilities and stockholders' (deficit) equity 28,284$ 28,178$ Condensed Consolidated Balance Sheets (in thousands) (unaudited)

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 oƯ-the-shelf therapeutic cancer immunotherapy candidates, including ELI-007 and ELI-008, that target BRAF-driven cancers and p53 hotspot mutations, respectively. For more information, please visit www.elicio.com. 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 oƯ-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 eƯiciently 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, 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.
