The ELI-002 7P vaccine represents a significant advancement in the realm of immunotherapy for pancreatic cancer, a disease notorious for its poor prognosis and limited treatment options. The vaccine’s focus on seven KRAS mutations is noteworthy since these mutations are prevalent in a quarter of all solid tumors, suggesting a wide potential impact. The study's progression to Phase 2 is a pivotal step in evaluating its efficacy in preventing relapse, which is a common and often fatal event in pancreatic cancer patients post-surgery.
Immunotherapies like ELI-002 7P aim to harness the body's immune system, specifically targeting tumor-specific antigens to elicit a robust T-cell response. The technology behind ELI-002, which targets the lymph nodes, is particularly innovative as it potentially enhances the immune system's ability to fight cancer. The emphasis on disease-free survival as a primary endpoint in Phase 2 underscores the treatment's potential to extend patients' lives by delaying or preventing cancer recurrence.
The proprietary AMP platform utilized in ELI-002 7P has shown promise in delivering targeted treatments to the immune system's 'command center,' which could be a game-changer in the efficacy of cancer vaccines. From a research perspective, the absence of dose-limiting toxicities in the Phase 1A safety evaluation is a positive indicator, suggesting that the treatment may be well-tolerated, an essential factor in patient compliance and overall treatment success.
The trial's design, which allows for crossover at the time of relapse, is an ethical approach that provides patients in the control arm access to the investigational vaccine if their cancer progresses. This design also offers additional data on the vaccine's performance in a more advanced disease setting. The exploratory endpoints, such as immunogenicity and tumor microenvironment analysis, will provide valuable insights into the biological mechanisms underpinning the vaccine's effectiveness and could guide future immunotherapy strategies.
The advancement of ELI-002 7P into Phase 2 trials is a critical milestone for Elicio Therapeutics and could have significant implications for the company's valuation and market position. The focus on a therapeutic vaccine for a subset of pancreatic cancer patients addresses a high unmet medical need, which could translate into a substantial market opportunity. The successful development of ELI-002 7P would not only benefit patients but could also position Elicio as a leader in KRAS-targeted therapies.
Investor interest is likely to be high given the potential market size and the innovative approach of the AMP platform. However, the long-term impact on the company's stock will hinge on the clinical outcomes of the Phase 2 trial, particularly the disease-free survival rates compared to the standard of care. Positive results could lead to increased investor confidence, while any setbacks might have a converse effect. As the trial progresses, stakeholders will be closely monitoring for interim analysis results and any signals of clinical benefit.

BOSTON, Jan. 17, 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 a Trial in Progress poster presentation on the Phase 1/2 (AMPLIFY-7P) study design at the ASCO Gastrointestinal Cancers (“ASCO GI”) Symposium being held January 18-20, 2024 in San Francisco, CA.
The poster describes AMPLIFY-7P, a Phase 1 and randomized Phase 2 study of ELI-002 7P, an investigational therapeutic cancer vaccine, administered as an adjuvant monotherapy treatment for patients with KRAS-mutated pancreatic ductal adenocarcinoma (“PDAC”).
“ELI-002 is an off-the-shelf cancer vaccine candidate developed with our proprietary Amphiphile (“AMP”) platform which provides a new ability to deliver these treatments effectively to the ‘command center’ of the immune response – the lymph nodes – where tumor-fighting T cells are generated and equipped,” said Christopher Haqq, M.D., Ph.D., Elicio’s Executive Vice President, Head of Research and Development, and Chief Medical Officer. “We are progressing our AMP-powered, lymph node-targeted cancer vaccine, ELI-002 7P, as a monotherapy in an adjuvant setting for patients with pancreatic cancer, and recently dosed the first patient in the randomized Phase 2 cohort. This study builds on positive preliminary data demonstrating our 2-peptide formulation of ELI-002 induced robust and durable tumor-directed mKRAS-specific T cell responses which correlated with tumor biomarker reduction or clearance, and reduced risk of relapse and death.”
Zev A. Wainberg, M.D., Professor of Medicine, University of California, Los Angeles (UCLA), Co-Director, the UCLA GI Oncology Program, added, “Patients with RAS mutated pancreatic cancers who have positive circulating tumor DNA post-surgery are often quick to relapse. Our current standard of care for these patients is observation – there are no treatments given during this ‘wait and see’ observation window before relapse. As we progress to Phase 2 of the study, we seek to compare ELI-002 7P to our current standard of care to further evaluate its antitumor activity and clinical benefit in the adjuvant setting as well as with bulkier cancer treated at the time of relapse in crossover patients with mKRAS-driven pancreatic cancer.”

Abstract #: TPS720
Poster Bd #: Q9
- ELI-002 7P is an investigational therapeutic cancer vaccine developed with Elicio’s proprietary lymph node-targeting AMP technology to treat cancers driven by seven common mutations in KRAS (G12D, G12R, G12V, G12A, G12C, G12S and G13D).
- AMPLIFY-7P is a Phase 1 and Phase 2 study of ELI-002 7P in patients with RAS mutated pancreatic and colorectal tumors after locoregional treatment. It is comprised of:
- Phase 1A safety evaluation of ELI-002 7P in which a cohort of ~13 patients received fixed 10.0 mg doses of AMP-CpG adjuvant at one of two AMP-Peptides 7P doses levels (1.4 mg or 4.9 mg); 1A cohort has been completed with no dose-limiting toxicities
- Phase 1B dose expansion to evaluate ELI-002 7P in a cohort of ~9-17 patients with colorectal cancer; planned but not currently active
- Phase 2 randomized 2:1 study that will assess disease free survival with recommended Phase 2 dose of ELI-002 7P (10.0 mg AMP-CpG with 4.9 mg AMP-peptides 7P) in ~90 patients with PDAC as compared to ~45 patients with PDAC who receive standard of care (observation) with crossover of the observation arm permitted at the time of confirmed radiographic relapse via iRECIST.
- Treatment included an immunization period of eight weeks in which six ELI-002 7P doses were administered, followed by a booster period (two months after immunization period) in which 4 additional ELI-002 7P doses were administered over the course of 4 weeks. Follow up continued up to 36 months.
- Patients receive up to 10 doses of Amph-peptides 7P 700 mcg each (4.9 mg total), together with Amph-CpG-7909 (10.0 mg) administered over a five-month treatment period.
- Primary endpoint of Phase 1 was safety and Phase 2 is disease free survival per investigator (iRECIST)
- Secondary endpoints are biomarker reduction or clearance of ctDNA or if ctDNA was not detectable, serum tumor antigen CA19-9, in the subset with positive baseline values, median overall survival, safety and iRECIST response rate in the crossover subset.
- Exploratory endpoints include the association of immunogenicity with high resolution HLA typing and evaluation of tumor-infiltrating T cells and the tumor microenvironment in the event biopsy tissue is available.
- A Phase 2 interim analysis is planned using group sequential design for control of overall alpha 0.10.
- Inclusion criteria includes:
- KRAS mutations (G12D, G12V, G12R, G12C, G12A, G12S or G13D)
- Eligible PDAC patients for Phase 2 must be within 6 months of completion of locoregional treatment for up-front resectable pathologically confirmed pancreatic cancer (Stage I-III) with radiographic NED (no evidence of disease).
- Phase 2 patients are included regardless of biomarker evidence of recurrent disease, however, those who have not recovered absolute lymphocytes to the normal range following cytotoxic therapy are excluded.
