Elicio Therapeutics Presents Late-Breaking Phase 2 AMPLIFY-7P Results at ESMO Congress 2026 and Announces Simultaneous Publication in Nature Medicine

• Multiple pre-specified subgroup analyses favored camupepimut (ELI-002 7P), including patients with and without detectable baseline ctDNA.

• Encouraging disease-free survival outcomes were observed in both ctDNA-negative (HR 0.51) and ctDNA-positive (HR 0.57) patients.

• Baseline prognostic imbalances provide important context for the intent-to-treat results, including a 53% lower risk of recurrence or death with camupepimut (multivariable adjusted HR 0.47; p=0.0086).

• Integrated clinical and translational findings provide clear direction for refining patient stratification, optimizing dosing and advancing Phase 3 development.

BOSTON, Oct. 23, 2026 (GLOBE NEWSWIRE) -- Elicio Therapeutics, Inc. (Nasdaq: ELTX) (“Elicio” or the “Company”), a clinical-stage biotechnology company developing next-generation immunotherapies for KRAS-driven cancers, today announced results from the randomized Phase 2 AMPLIFY-7P study of camupepimut (ELI-002 7P), presented in a late-breaking Proffered Paper oral session at the European Society for Medical Oncology (“ESMO”) Congress 2026 in Madrid, Spain, and simultaneously published in Nature Medicine: "Lymph node-targeted, mKRAS-specific amphiphile vaccine in pancreatic cancer: the randomized phase 2 AMPLIFY-7P trial".

Across multiple pre-specified analyses, camupepimut demonstrated consistent and favorable treatment-effect trends in patients with and without detectable baseline ctDNA and in patients without prior radiation. While the study did not meet its pre-specified primary disease-free survival (“DFS”) endpoint in the intent-to-treat (“ITT”) population (HR 0.85), the results should be considered in the context of a baseline imbalance in ctDNA positivity, a strong predictor of recurrence, which was more prevalent in the camupepimut arm (20.8% vs. 12.5%). Translational analyses also demonstrated broad, persistent mutant KRAS-specific T-cell responses associated with longer DFS. Together, these findings inform a refined Phase 3 development strategy.

“The AMPLIFY-7P results provide important new insights into camupepimut’s clinical activity and reinforce our confidence in its potential for patients with pancreatic cancer,” said Robert Connelly, President and Chief Executive Officer of Elicio. “We are encouraged by the consistent treatment-effect trends across pre-specified patient groups, including patients with and without detectable baseline ctDNA, and by the strong mKRAS-specific immune responses associated with clinical outcomes. These insights give us clear direction for our potential Phase 3 strategy.”

• In the 93 patients with baseline ctDNA-negative status, median DFS was not reached in the camupepimut arm vs. 21.2 months in the observation arm (HR 0.51; nominal p=0.0280). Recurrence or death was observed in 27.4% (17/62) of camupepimut-treated patients vs. 48.4% (15/31) of patients in observation.

• A consistent treatment effect was also observed in the smaller, higher-risk baseline ctDNA-positive subgroup (n=26). Median DFS was 4.3 months with camupepimut vs. 1.9 months with observation (HR 0.57; nominal p=0.0489).

• Prior radiation predicted lower baseline lymphocyte counts and reduced camupepimut-induced mKRAS T cell responses. In pre-specified analysis, patients who had not received prior radiation (n=106) had median DFS of 23.8 months with camupepimut vs. 10.4 months with observation (HR 0.59; nominal p=0.0221).

• Baseline ctDNA status emerged as a particularly strong prognostic marker. In a pooled analysis across treatment groups, median DFS was 4.2 months for ctDNA-positive patients versus 24.0 months for ctDNA-negative patients (HR 6.56; nominal p<0.000001). Patients with baseline ctDNA positivity were more prevalent in the camupepimut arm (20.8%; 20/96) than in the observation arm (12.5%; 6/48).

• A multivariable model adjusting for baseline factors estimated an association between camupepimut treatment and lower recurrence risk (adjusted HR 0.47; p=0.0086), while elevated CA19-9 (adjusted HR 3.16; p<0.0001) and positive baseline ctDNA (adjusted HR 5.99; p<0.0001) were associated with higher risk.

• Six-month DFS was 75.7% with camupepimut vs. 61.7% with observation, a 14.0 percentage-point difference immediately following the treatment period supports evaluating treatment duration in future studies.

• Camupepimut induced mutant KRAS-specific T-cell responses in 99% of evaluable treated patients (median 44.3-fold increase from baseline. Among patients evaluated for T-cell subsets, 85% generated both CD4 and CD8 responses. Responses persisted at least 46 weeks from baseline in 95.5% of evaluable treated patients; 13 of 15 patients in a selected subset showed responses to additional tumor targets.

• In an exploratory analysis, stronger camupepimut-induced mutant KRAS-specific T-cell responses were associated with significantly longer DFS. Median DFS was not reached among patients with immune responses above a previously identified threshold (82%, 74/90) vs. 6.08 months among those below the threshold (HR 0.22; nominal p<0.0001).

• Camupepimut was generally well tolerated, with no new safety signals observed. Grade 3 or higher adverse events occurred in 10.4% of patients receiving camupepimut vs. 14.6% under observation; serious adverse events occurred in 6.3% and 8.3%, respectively. No adverse events led to withdrawal of study medication.

“The Phase 2 translational findings build on and reinforce our Phase 1 observations, demonstrating that camupepimut generates broad and persistent mutant KRAS-specific T-cell responses, with stronger immune responses associated with longer DFS,” said Christopher Haqq, M.D., Ph.D., Executive Vice President, Head of Research and Development and Chief Medical Officer of Elicio. “These observations across both baseline ctDNA subgroups and camupepimut’s favorable safety and tolerability profile provide a strong scientific and clinical rationale for a refined Phase 3 design incorporating optimized patient stratification, extended treatment duration and potential combination approaches.”

Elicio plans to discuss the totality of AMPLIFY-7P findings with the U.S. Food and Drug Administration to inform a potential Phase 3 study in adjuvant pancreatic cancer. Areas for consideration include baseline ctDNA and other prognostic factors in stratification and patient selection, treatment duration, and combination strategies intended to deepen or sustain mutant KRAS-specific immune activity. Any future study design remains subject to regulatory discussion and further development planning.

AMPLIFY-7P Phase 2 is a randomized study evaluating camupepimut versus observation in patients with mutant KRAS-driven pancreatic ductal adenocarcinoma following completion of standard locoregional therapy. The study enrolled 144 patients across 24 U.S. clinical sites.

Elicio’s lead product candidate, ELI-002, is a structurally novel investigational Amphiphile (“AMP”) cancer immunotherapy that targets cancers driven by mutations in the KRAS gene, a prevalent driver of many human cancers. ELI-002 is comprised of AMP-modified mutant KRAS peptide antigens and ELI-004, an AMP-modified CpG oligodeoxynucleotide adjuvant, and is available as an off-the-shelf subcutaneous administration.

Camupepimut (ELI-002 7P), the seven-peptide formulation, was evaluated in the randomized Phase 2 AMPLIFY-7P trial in patients with mKRAS-driven pancreatic cancer. The ELI-002 7P formulation is designed to provide immune response coverage against seven of the most common KRAS mutations present across multiple solid tumors.

Elicio Therapeutics, Inc. (Nasdaq: ELTX) is a clinical-stage biotechnology company advancing next-generation immunotherapies for the treatment of KRAS-driven cancers, including mKRAS-positive pancreatic and colorectal cancers. Elicio intends to build on recent clinical findings in the personalized cancer immunotherapy space to develop effective, off-the-shelf immunotherapies.

Elicio’s AMP technology aims to enhance the education, activation and amplification of cancer-specific T cells relative to conventional immunotherapy strategies, with the goal of promoting durable cancer immunosurveillance in patients. Elicio’s ELI-002 7P lead program is an off-the-shelf immunotherapy candidate targeting the most common KRAS mutations, which drive approximately 25% of all solid tumors.

Off-the-shelf immunotherapy approaches have the potential benefits of low cost, rapid, commercial-scale manufacturing and rapid availability of drug to patients, especially in neoadjuvant settings and for prophylaxis in high-risk patients, contrary to personalized immunotherapy approaches.

Elicio’s pipeline includes additional off-the-shelf therapeutic cancer immunotherapy candidates, including ELI-007 and ELI-008, which target BRAF-driven cancers and p53 hotspot mutations, respectively.
