Study Overview
Brief Summary
RATIONALE: Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.
PURPOSE: Phase II trial to study the effectiveness of bortezomib in treating patients who have diffuse large B-cell lymphoma that is refractory to previous chemotherapy.
Detailed Description
OBJECTIVES:
- Determine the overall response rate in patients with chemotherapy-refractory diffuse large B-cell lymphoma treated with bortezomib.
- Determine the safety and tolerability of this drug in these patients.
- Determine the time to disease progression in patients treated with this drug.
- Determine the possible mechanism of resistance to this drug in these patients.
OUTLINE: This is an open-label, multicenter study.
Patients receive bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed at 20 days and then every 3 months thereafter.
