Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Progression-free Survival (PFS)
Time Frame: 4 months
|
PFS is defined as the number of mPDAC patients free of progression at 4 months since the initiation of therapy - disease progression (progressive disease [PD] 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 =>30percent decrease in sum of diameters of target lesions, Progressive Disease (PD) is >20percent increase in sum of diameters of target lesions, Stable Disease (SD) is <30percent decrease or <20percent increase in sum of diameters of target lesions.
|
4 months
|
Objective Response Rate (ORR)
Time Frame: 3 years
|
ORR is defined as the number of mCRC patients who are administered at least 1 dose of mKRAS peptide vaccine achieving a complete response (CR) or 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 =>30percent decrease in sum of diameters of target lesions, progressive disease (PD) is >20percent increase in sum of diameters of target lesions, stable disease (SD) is <30percent decrease or <20percent increase in sum of diameters of target lesions.

Objective Response Rate (ORR) per RECIST 1.1
Time Frame: 3 years
|
ORR is defined as the number of mPDAC patients who are administered at least 1 dose of mKRAS peptide vaccine and balstilimab +/- botensilimab achieving a complete response (CR) or 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% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.
Estimation based on the Kaplan-Meier curve.

CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.

DCR is defined as the number of patients who are administered ≥ 1 dose of mKRAS peptide vaccine achieving a complete response (CR) or partial response (PR) and stable disease (SD) based on the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) at 6 months post first vaccination.
CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.

|
Disease Control Rate (DCR)
Time Frame: 12 months
|
DCR is defined as the number of patients who are administered ≥ 1 dose of mKRAS peptide vaccine achieving a complete response (CR) or partial response (PR) and stable disease (SD) based on the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) at 12 months post first vaccination.
CR = disappearance of all target lesions, PR is =>30% decrease in sum of diameters of target lesions, progressive disease (PD) is >20% increase in sum of diameters of target lesions, stable disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.

12 months
|
Progression-free Survival (PFS) per RECIST 1.1
Time Frame: 3 years
|
PFS is defined as the time from cycle 1, day 1 of KRAS vaccine and balstilimab and botensilimab until first documented local disease progression (progressive disease [PD] 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% decrease in sum of diameters of target lesions, Progressive Disease (PD) is >20% increase in sum of diameters of target lesions, Stable Disease (SD) is <30% decrease or <20% increase in sum of diameters of target lesions.
