Study Summary

This phase II trial studies the effect of P140K MGMT hematopoietic stem cells, O6-benzylguanine, temozolomide, and carmustine in treating participants with supratentorial glioblastoma or gliosarcoma who have recently had surgery to remove most or all of the brain tumor (resected). Chemotherapy drugs, such as 6-benzylguanine, temozolomide, and carmustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing. Placing P140K MGMT, a gene that has been created in the laboratory into bone marrow making the bone more resistant to chemotherapy, allowing intra-patient dose escalation which kills more tumor cells while allowing bone marrow to survive.

Primary Outcome

To evaluate and compare the feasibility of introducing and expressing P140K MGMT cDNA using a lentiviral-based provirus in autologous hematopoietic stem cells harvested from newly diagnosed IDH-1 WT GBM with unmethylated MGMT promoter using two different sequences of stem cell mobilization. 1\. What percent of patients who enter trial can complete treatment.
