Mutant MGMT Gene Transfer Into Human Hematopoietic Progenitors to Protect Hematopoiesis During O6-Benzylguanine (BG, NSC 637037) and Carmustine Followed by Temozolomide Therapy of Advanced Solid Tumors

Study Summary

RATIONALE: Gene therapy may improve the body's ability to fight cancer or make the cancer more sensitive to chemotherapy. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase I trial is studying the side effects and best dose of gene therapy together with chemotherapy in treating patients with advanced solid tumors or non-Hodgkin's lymphoma.

Interventions

filgrastimBIOLOGICAL
Patients receive filgrastim (G-CSF) subcutaneously (SC) once daily on days 1-5 (or G-CSF twice daily alone for 4-5 days).
sargramostimBIOLOGICAL
Patients receive sargramostim (GM-CSF) subcutaneously (SC) once daily on days 1-5 (or G-CSF twice daily alone for 4-5 days).
therapeutic autologous lymphocytesBIOLOGICAL
No description available.
O6-benzylguanineDRUG
Patients receive O6-benzylguanine (BG) IV over 1 hour every 6 weeks for 5 courses. Four weeks after the completion of BG and carmustine, patients receive BG IV over 1 hour every 4 weeks for up to 5 courses, in the absence of hematologic toxicity. Patients with responding disease may continue to receive BG and temzolomide in the absence of disease progression or unacceptable toxicity.
carmustineDRUG
Patients receive carmustine IV over 1 hour every 6 weeks for 5 courses.Cohorts of 3-6 patients receive escalating numbers of CD34 stem cells targeted for retroviral infection and escalating doses of carmustine.
temozolomideDRUG
Four weeks after the completion of BG and carmustine, patients receive temozolomide IV over 1 hour every 4 weeks for up to 5 courses, in the absence of hematologic toxicity. Patients with responding disease may continue to receive BG and temzolomide in the absence of disease progression or unacceptable toxicity.
in vitro-treated peripheral blood stem cell transplantationPROCEDURE
Approximately 72 hours after the end of the first course of chemotherapy, patients receive reinfusion of retrovirally-transduced hematopoietic stem cells over 5-10 minutes. Cohorts of 3-6 patients receive escalating numbers of CD34 stem cells targeted for retroviral infection and escalating doses of carmustine.
