Trial Summary

What is the purpose of this trial?

This trial is testing a custom-made vaccine designed to help the immune system attack brain cancer cells. It targets patients with a specific type of brain cancer that hasn't responded to usual treatments. The vaccine works by teaching the immune system to recognize and destroy cancer cells based on unique markers.

Eligibility Criteria

This trial is for adults with newly diagnosed, unmethylated glioblastoma who've had a craniotomy or resection. Participants must consent to genome sequencing and agree to use contraception. They should have normal organ function, not be on high-dose steroids, and can't have other cancers within the last 3 years or any immune system disorders.

Inclusion Criteria

Patients who had prior craniotomy with biopsy, subtotal resection, total gross resection, or re-resection will be permitted.
Consent to genome sequencing and dbGaP-based data sharing and has provided or will provide germline (PBMC) and tumor DNA/RNA samples of adequate quality for sequencing. (Acquisition of specimens for sequencing and the sequencing itself may be done as part of routine care or another research project.)
Normal bone marrow and organ function as defined below:
