Study Summary
This trial will test a personalized neoantigen-based DNA vaccine, combined with PD-1 blockade, to maximize tumor-specific response and minimize toxicity in people newly diagnosed with glioblastoma.
Who is the study for?
This trial is for adults with newly diagnosed, unmethylated glioblastoma who haven't had prior immunotherapy. Participants must have adequate organ function, agree to use contraception, and can consent to genome sequencing. They should not have certain other cancers within the last 3 years or conditions that could interfere with the study.Check my eligibility
What is being tested?
The trial tests a personalized neoantigen DNA vaccine combined with Retifanlimab PD-1 blockade therapy in patients with glioblastoma. It aims to enhance T cell responses against cancer while keeping side effects low and will set the stage for future efficacy studies.See study design
What are the potential side effects?
Potential side effects include immune-related reactions due to PD-1 blockade (like inflammation of organs), reactions at injection sites from the vaccine or electroporation device, fatigue, blood disorders, and increased risk of infections.

Study Objectives
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Safety as measured by treatment-related dose-limiting toxicity (DLT) rate related to vaccination
Secondary outcome measures
Immunogenicity as measured by T cell receptor (TCR) sequencing to assess diversity of clonality and putative antigen specificity
Immunogenicity as measured by T-cell phenotype, myeloid derived suppressor cell frequency (MDSC) assessed by flow cytometry
Immunogenicity as measured by pro- and anti-inflammatory chemokine analysis and cytokine analysis in plasma as assessed by multiplex ELISA

Experimental Treatment
Group I: Cohort B: Personalized neoantigen DNA vaccine + retifanlimabExperimental Treatment3 Interventions
Cohort B will receive the personalized neoantigen DNA vaccine via electroporation mediated IM injection plus concurrent retifanlimab beginning with Dose 1 and continuing for a total of 6 doses.
The personalized neoantigen DNA vaccine will be given once every 28 days for up to 6 doses. Retifanlimab is given at a fixed dose of 500 mg every 28 days.
Patients may receive up to 6 doses of personalized neoantigen DNA vaccine and up to 12 months total of retifanlimab
Group II: Cohort A: Personalized neoantigen DNA vaccine + retifanlimabExperimental Treatment3 Interventions
Cohort A will receive the personalized neoantigen DNA vaccine via electroporation mediated IM injection alone during the first two priming doses, then concurrently with retifanlimab during the subsequent boosting doses (Doses 3 through 6)
The personalized neoantigen DNA vaccine will be given once every 28 days for up to 6 doses. Retifanlimab is given at a fixed dose of 500 mg every 28 days.
Patients may receive up to 6 doses of personalized neoantigen DNA vaccine and up to 12 months total of retifanlimab
