Brief Summary:
The purpose of this study is 1) to evaluate the feasibility of manufacturing a patient-specific neoantigen cancer vaccine, which involves predicting the patient's neoantigens and generating a vaccine that encodes the predicted neoantigens; and, 2) to identify and select patients who may be eligible for a shared neoantigen cancer vaccine where their tumor contains a specific shared mutation and who have the correct HLA allele capable of presenting the neoantigen derived from the tumor-specific mutation.

Condition or disease Intervention/treatment
Non Small Cell Lung Cancer Colorectal Cancer Gastroesophageal Adenocarcinoma Urothelial Carcinoma Pancreatic Ductal Adenocarcinoma Procedure: Blood collection for research (next-generation sequencing [NGS]) Procedure: Blood collection for research (HLA typing)

Detailed Description:

Gritstone is developing two neoantigen-based cancer vaccines: the first is a patient-specific cancer vaccine that requires a manufacturing period for each patient and the second is an off-the-shelf cancer vaccine that targets shared neoantigens.

The process of generating a patient-specific neoantigen cancer vaccine involves multiple steps, including collection of patient tumor and blood specimens, performing next-generation sequencing (NGS), predicting the neoantigens to be included in the patient-specific vaccine, and the manufacture and release of the patient-specific vaccine. Gaining experience in managing the manufacturing process will provide important insights and experience regarding this process to be used in operationalizing future clinical trials.

Selecting patients who may be eligible to receive a shared neoantigen vaccine requires first identifying patients whose tumor possesses a neoantigen derived from an oncogenic mutation that is encoded by the vaccine, and then determining whether the patient expresses a matching HLA allele for antigen presentation.

Study participants will not receive any investigational treatment as part of this trial. Patients screened in this study may be able to enroll in a separate investigational treatment study sponsored by Gritstone Oncology, provided that the patient meets the specified eligibility criteria for that treatment study.

Group/Cohort Intervention/treatment
1 - patient-specific neoantigen cancer vaccine production Procedure: Blood collection for research (next-generation sequencing [NGS])
Participants will have whole blood collected for next-generation sequencing (NGS).

Procedure: Blood collection for research (HLA typing)
Participants will have whole blood collected for HLA typing.

2 - shared neoantigen cancer vaccine screening Procedure: Blood collection for research (HLA typing)
Participants will have whole blood collected for HLA typing.




Primary Outcome Measures :
  1. Group 1 only: Presence of neoantigens sufficient to warrant patient-specific vaccine manufacture [ Time Frame: At study enrollment ]
  2. Group 1 only: Percentage of patients for whom patient-specific vaccine is successfully manufactured (defined as meeting release criteria) [ Time Frame: Up to approximately 20 weeks ]
  3. Group 2 only: Percentage of patients with at least one of the twenty specified shared mutations contained in the expression cassette and a matching HLA allele for neoantigen presentation [ Time Frame: Up to approximately 2 weeks ]

Biospecimen Retention:   Samples With DNA
  • whole blood specimen, for HLA typing (all participants)
  • FFPE tumor material from a biopsy or resection, for sequencing to identify tumor-specific mutations (Group 1 participants only)
  • whole blood specimen, for sequencing of normal genome (Group 1 participants only)
