Brief Summary:
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.

Minimal Residual Disease KRAS G12D KRAS G12R NRAS G12D NRAS G12R Pancreatic Ductal Adenocarcinoma Colorectal Cancer Non-small Cell Lung Cancer Ovarian Cancer Cholangiocarcinoma Bile Duct Cancer Gallbladder Carcinoma Drug: ELI-002 2P Phase 1

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 pharmcodynamic 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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Determine the MTD of ELI-002 and the RP2D [ Time Frame: 28 days after first dose ]
    The MTD is defined as the highest dose level for which <33% of subjects had a dose-limiting toxicity.

  2. Evaluate the safety of ELI-002 [ Time Frame: 30 days after last dose ]
    Safety will be assessed by the incidence of adverse events (AEs) and clinically significant laboratory tests and vital signs.


Secondary Outcome Measures :
  1. Determine the biomarker reduction and clearance rate [ Time Frame: 6 months ]
    The ctDNA reduction and clearance rate is defined as the reduction or clearance of ctDNA , or if ctDNA was not detectable at baseline, serum tumor biomarker reduction or clearance compared to baseline.
