• Status: Completed
• Trial end date: 2000-03-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of carboplatin in patients with progressive glioma.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Criteria
