Status:
Completed
Trial end date:
1969-12-31
Target enrollment:
0
Participant gender:
All
Summary
Phase I trial to study the effectiveness of O6-benzylguanine and carmustine in treating children who have refractory CNS tumors. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
Phase:
Phase 1
