Gefitinib in Treating Patients With Malignant Mesothelioma

• Status: Completed
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Phase II trial to study the effectiveness of gefitinib in treating patients who have malignant mesothelioma. Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of malignant mesothelioma

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

Details

• Lead Sponsor: National Cancer Institute (NCI)
• Treatments: Gefitinib
