A Study of ELI-002 7P in Subjects With KRAS/NRAS Mutated Solid Tumors

This is a Phase 1/2 study to assess the safety and efficacy of ELI-002 7P immunotherapy (a lipid-conjugated immune-stimulatory oligonucleotide [Amph-CpG-7909] plus a mixture of lipid-conjugated peptide-based antigens [Amph-Peptides 7P]) as adjuvant treatment in subjects with solid tumors with mutated KRAS/NRAS. This study builds on the experience obtained with related product ELI-002 2P, which was studied in protocol ELI-002-001 under IND 26909.

About this study

The study consists of 3 phases: Phase 1A, Phase 1B, and Phase 2. In Phase 1A, seven Amph modified KRAS and NRAS peptides, G12D, G12R, G12V, G12A, G12C, G12S, G13D (Amph-Peptides 7P) will be evaluated in combination with recommended Phase 2 dose of Amph-CpG-7909 (10.0mg). This Amph-CpG-7909 dose will be evaluated with two Amph-Peptides 7P dose levels (1.4mg and 4.9mg) in 6 subjects per dose level. Following enrollment of these 12 subjects, the independent data monitoring committee (IDMC) will decide if another 6 subjects should be enrolled or if the dose can be determined for Phase 1B and Phase 2 portions of the study to be opened. If another 6 subjects are enrolled to Phase 1A, the IDMC will meet again to decide upon the dose for Phase 1B and Phase 2 prior to opening these portions of the study.

In Phase 1B, one dose expansion cohort of up to 17 colorectal cancer [CRC] subjects may be added to evaluate for preliminary evidence of biomarker response, including circulating tumor deoxyribonucleic acid (ctDNA) and/or serum tumor biomarker (such as CA19-9 and CEA) reduction and clearance in KRAS and NRAS.

In Phase 2, an additional 135 PDAC subjects will be randomized 2:1 (ELI-002 7P versus observation) to further evaluate antitumor activity. Subjects randomized to ELI-002 7P will receive subcutaneous (SC) injections of ELI-002 7P during Immunization and Booster Periods. Subjects randomized to observation will have the same safety and efficacy evaluations and will follow the same assessment schedule as subjects randomized to ELI-002 7P but will not receive study treatment. Subjects randomized to observation will be able to elect to cross-over to ELI-002 7P treatment in the event of confirmed disease progression.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • KRAS/NRAS mutated (G12D, G12R, G12V, G12A, G12C, G12S, G13D) solid tumor
  • Phase 1 only: positive for circulating tumor DNA and/or elevated serum tumor biomarkers (such as CA19-9 and CEA) despite prior standard therapy including surgery and chemotherapy/radiation therapy where applicable
  • Screening CT is negative for recurrent disease
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Exclusion criteria

  • Presence of tumor mutations where specific therapy is approved
  • Known brain metastases
  • Use of immunosuppressive drugs

Treatment and study plan

ELI-002 7P

Drug

ELI-002 Amph-CpG-7909 admixed with ELI-002 Amph-Peptides 7P administered via SC injection weekly for 4 consecutive weeks, followed by bi-weekly injections over 4 weeks, during the Immunization Period; additional SC injections weekly for 4 weeks during the Booster Period (the two periods are separated by 2 months of no dosing)

Primary outcomes

  1. Phase 1: Evaluate the safety of ELI-002 7P

    Time frame: 28 days after the first dose of ELI-002 7P

    Safety will be assessed by the incidence of adverse events (AEs) and clinically significant changes in laboratory tests and vital signs

  2. Phase 2: Compare ELI-002 7P versus standard of care (SOC; observation) in DFS (disease free survival)

    Time frame: After the last radiographic assessment at Visit 26 (Week 150)

    DFS is assessed by the investigator through computed tomography (CT) imaging or magnetic resonance imaging (MRI) with contrast and using iRECIST criteria

Secondary outcomes

  1. Phase 2: Overall Survival (OS)

    Time frame: After Visit 13 (Week 20)

    To compare OS between cohorts, ELI-002 7P vs Observation

  2. Phase 1 and Phase 2: Determine the biomarker reduction or clearance rate

    Time frame: 6 months

    The ctDNA reduction or clearance is defined as reduction or clearance of ctDNA from baseline, or if ctDNA was not detectable at baseline, serum tumor biomarker (such as CA19-9 and CEA) reduction and clearance compared to baseline

  3. Phase 2: Determine the 1-year DFS

    Time frame: 1 year

    Compare between cohorts, ELI-002 7P vs Observation, the 1-year DFS

  4. Phase 2: Evaluate the safety of ELI-002 7P

    Time frame: 30 days after the last ELI-002 7P dose

    Safety will be assessed by the incidence of AEs and clinically significant laboratory tests and vital signs
