February 28, 2024 updated by: Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins
Pooled Mutant KRAS-Targeted Long Peptide Vaccine Combined With Nivolumab and Ipilimumab for Patients With Resected MMR-p Colorectal and Pancreatic Cancer
Phase 1 study for patients with resected PDAC after neoadjuvant and/ or adjuvant chemotherapy and/or radiation, as well as patients with metastatic colorectal cancer who have exposure to 2 or more lines of chemotherapy, to evaluate safety and the immune response to pooled mutant-KRAS peptide vaccine (KRAS peptide vaccine) with poly-ICLC adjuvant in combination with nivolumab and ipilimumab.

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.

- 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.
- Has active autoimmune disease that has required systemic treatment in the past 2 years, or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents.
- Known history or concurrent interstitial lung disease.
- Has a pulse oximetry < 92% on room air.
- Requires the use of home oxygen.
- Infection with HIV or hepatitis B or C.
- Uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, symptomatic congestive heart failure, unstable angina, cardiac arrhythmia, metastatic cancer, or psychiatric illness/social situations that would limit compliance with study requirements.
- Has been diagnosed with another cancer or myeloproliferative disorder within the past 5 year.
- Has a diagnosis of immunodeficiency.
- Presence of any tissue or organ allograft, regardless of need for immunosuppression, including corneal allograft. Patients with a history of allogeneic hematopoietic stem cell transplant will be excluded.
- Any other sound medical, psychiatric, and/or social reason as determined by the Investigator.
- Unwilling or unable to follow the study schedule for any reason.
- Are pregnant or breastfeeding.
- For metastatic MSS CRC and Reinduction Treatment Cohorts, any peritoneal involvement by the tumor.
- For metastatic MSS CRC and Reinduction Treatment Cohorts, any radiological or clinical pleural effusions or ascites.
- For metastatic MSS CRC and Reinduction Treatment Cohorts, patients on parenteral nutrition.
- For metastatic MSS CRC and Reinduction Treatment Cohorts, patients with any single liver metastases greater than 5 cm or greater > 50% liver involvement.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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.
|
4 years
|
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

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.

4 years
|
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.
