Bortezomib in Treating Patients With Diffuse Large B-Cell Lymphoma That Is Refractory To Chemotherapy

January 7, 2013 updated by: Jonsson Comprehensive Cancer Center

A Phase II Study Of PS-341 (VELCADE) In Chemotherapy-Refractory Diffuse Large B-Cell Lymphoma (DLBCL)

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.

PROJECTED ACCRUAL: A total of 22-40 patients will be accrued for this study.
