About this study

Official title: First in Human Phase 1 Trial of ELI-002 Immunotherapy as Treatment for Subjects With Kirsten Rat Sarcoma (KRAS) Mutated Pancreatic Ductal Adenocarcinoma and Other Solid Tumors

This is a Phase 1 study to assess the safety and efficacy of ELI-002 immunotherapy (a lipid-conjugated immune-stimulatory oligonucleotide [Amph-CpG-7909] plus a mixture of lipid-conjugated peptide-based antigens [Amph-Peptides]) as adjuvant treatment of minimal residual disease (MRD) in subjects with KRAS/neuroblastoma ras viral oncogene homolog (NRAS) mutated PDAC or other solid tumors.

Read the detailed description

This is a Phase 1 dose escalation study in which ELI-002 2P (Amph modified KRAS peptides, Amph-G12D and Amph-G12R admixed with admixed Amph-CpG-7909) will be evaluated, with plans to transition to the ELI-002 7P drug product containing all 7 Amph-Peptides (G12D, G12R, G12V, G12A, G12C, G12S, G13D) in future clinical trials.

The study is an open-label, dose-escalation, 3+3 design in which approximately 18 subjects will be treated in 3 planned dose level cohorts. Increasing doses of Amph-CpG-7909 will be evaluated sequentially. Additional cohorts may be added to explore intermediate or higher dose levels based on cumulative safety review and preliminary review of pharmacodynamic responses. Safety and pharmacodynamic data will be evaluated and a recommended Phase 2 dose (RP2D) will be determined in consideration of a maximum tolerated dose (MTD) if observed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Participant Incidence of Treatment-emergent Adverse Events Considered by the Investigator as Related to ELI-002

    The safety of ELI-002 was monitored through adverse events, including those considered related to treatment by the investigator

    Measured: Adverse events were collected through 28 days after the last dose

Secondary outcomes (4)
  1. The Proportion of Participants With Biomarker Reduction

    A biomarker reduction was any decrease from baseline in circulating tumor DNA (ctDNA) and/or serum tumor antigen levels (carbohydrate antigen 19-9 [CA19-9] or carcinoembryonic antigen [CEA]).

    Measured: 6 months

  2. The Proportion of Participants With Biomarker Clearance

    Biomarker clearance was defined as no detectable ctDNA, CA19-9, or CEA at post-treatment time points.

    Measured: 6 months

  3. The Proportion of Participants With Biomarker Reduction by Biomarker Type

    A biomarker reduction was any decrease from baseline in ctDNA and/or serum tumor antigen levels (CA19-9 or CEA).

    Measured: 6 months

  4. The Proportion of Participants With Biomarker Clearance by Biomarker Type

    Biomarker clearance was defined as no detectable ctDNA, CA19-9, or CEA at post-treatment time points

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ELI-002 2P in people with Minimal Residual Disease and KRAS G12D, run by Elicio Therapeutics at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Jan 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Participant Incidence of Treatment-emergent Adverse Events Considered by the Investigator as Related to ELI-002 (time frame: Adverse events were collected through 28 days after the last dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04853017, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2025.
