- Number of participants experiencing study drug-related toxicities [ Time Frame: 2 years ]Number of participants experiencing study drug-related adverse events Grade 3 or higher as defined by CTCAE v5.0
- Fold change in interferon-producing mutant-KRAS-specific cytotoxic (CD8) and helper (CD4) T cells at 16 weeks [ Time Frame: Baseline, 16 weeks ]Evaluated by the fold change in interferon-producing mutant-KRAS-specific CD8 and CD4 T cells after vaccination at 16 weeks compare to pre-vaccination baseline.
- Disease Free Survival (DFS) [ Time Frame: 4 years ]DFS is defined as the number of months from cycle 1, day 1 of vaccination until the first documented disease recurrence or death due to any cause in patients with resected PDAC. Will be censored at the date of the last progressive disease evaluation if no event observed.
- Percentage change of interferon (IFN)-γ-producing mutant-KRAS-specific CD8 and CD4 T cells [ Time Frame: 2 years ]Percent change of IFN-γ-producing mutant-KRAS-specific CD8 and CD4 T cells at any time after vaccination.
- Objective Response Rate (ORR) per RECIST 1.1 [ Time Frame: 4 years ]ORR is defined as the number of patients with metastatic microsatellite stable (MSS) CRC who are administered at least one dose of KRAS achieving a complete response (CR) partial response (PR) based on the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) at any time during the study. CR = disappearance of all target lesions, PR is =>30 percent decrease in sum of diameters of target lesions, progressive disease (PD) is >20 percent increase in sum of diameters of target lesions, stable disease (SD) is <30 percent decrease or <20 percent increase in sum of diameters of target lesions.
- Progression-free Survival (PFS) for RECIST 1.1 [ Time Frame: 4 years ]PFS is defined as the numbers of months from the date of the first vaccine dose to the date of disease progression or death due to any cause, which ever occurs first, for Metastatic Colorectal Cancer (mCRC) patients. Censored at the date of last scan for subjects without documentation of disease progression (PD) at the time of analysis or relapse from complete response [CR] as assessed using RECIST 1.1 criteria) or death due to any cause. Per RECIST 1.1 criteria, CR = disappearance of all target lesions, Partial Response (PR) is =>30 percent decrease in sum of diameters of target lesions, Progressive Disease (PD) is >20 percent increase in sum of diameters of target lesions, Stable Disease (SD) is <30 percent decrease or <20 percent increase in sum of diameters of target lesions.
- Overall Survival (OS) [ Time Frame: 4 years ]OS will be measured as the number of months from the date of first vaccine dose until death or end of follow up. OS will be censored on the date the subject was last known to be alive for subjects without documentation of death at the time of analysis. Estimation based on the Kaplan Meier Curve

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
PDAC or metastatic MSS CRC Cohort:
-
Have histologically or cytologically - proven cancer of the pancreas (PDA) or MSS colorectal (CRC) in one of the following categories:
- PDAC must have no evidence of disease and last dose of neoadjuvant and/or adjuvant chemotherapy/radiation therapy/or surgery must be < 6 months from study entry.
- Metastatic MSS CRC after exposure to 2 more lines of chemotherapy in the metastatic setting including 5-flurouracil, irinotecan, and oxaliplatin exposure. Patients treated with FOLFOXIRI may enroll after progression or intolerance to that regimen.
- For metastatic MSS CRC cohort, must have tumor lesions amenable to repeated biopsy, and patient's acceptance to have a tumor biopsy of an accessible lesion at baseline and on treatment if the lesion can be biopsied with acceptable clinical risk (as judged by the Principal Investigator).
- For metastatic MSS CRC patients, must have measurable disease per RECIST 1.1.
Reinduction Treatment Cohort:
- Have a single site of locoregional recurrence or distant metastasis noted on imaging > 12 months after the first dose of the mutant KRAS peptide vaccine with poly-ICLC adjuvant.
- Have completed definitive treatment for solitary recurrence per standard-of-care (e.g. surgical resection, radiation, and/or chemotherapy) <6 months prior to screening for reinduction treatment.
Both Cohorts:
*Age ≥18 years.
- Have sufficient archival tumor tissue for next-generation sequencing (NGS) and immune-phenotyping.
- Have one of the KRAS mutations included in the vaccine at the time of vaccination expressed in tumor.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
- Life expectancy of greater than 6 months.
- Patients must have adequate organ and marrow function defined by study-specified laboratory tests prior to initial study drug.
- Woman of childbearing potential must have a negative pregnancy test and follow contraceptive guidelines as defined per protocol.
- Men must use acceptable form of birth control while on study.
- Ability to understand and willingness to sign a written informed consent document.
Exclusion Criteria
- If expected to require any other form of systemic or localized antineoplastic therapy while on study.
-
Within 2 weeks prior to first dose of study drug.
- Systemic or topical steroids corticosteroids at immunosuppressive doses (> 10 mg/day of prednisone or equivalent). Inhaled or topical steroids, and adrenal replacement steroid doses ≤ 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
- Any palliative or adjuvant radiation or gamma knife radiosurgery.
- Any chemotherapy.
-
Within 4 weeks prior to first dose of study drug.
- Any investigational cytotoxic drug.
- Any investigational device.
- Has received a live vaccine.
- Received any allergen hyposensitization therapy.
- Received any growth factors, e.g. granulocyte-colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM-CSF), erythropoietin.
- Any major surgery.
- PDAC or metastatic MSS CRC Cohort: Prior treatment with immunotherapy agents (including, anti-PD-1, anti-PD-L1, anti-PD-L2, anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA4), etc.).
- Hypersensitivity reaction to any monoclonal antibody.
- Known history or evidence of brain metastases.
