Bortezomib and Rituximab in Treating Patients With Relapsed or Refractory B-Cell Non-Hodgkin's Lymphoma

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

Summary

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving bortezomib together with rituximab may be an effective treatment for non-Hodgkin's lymphoma.

PURPOSE: This phase II trial is studying how well giving bortezomib together with rituximab works in treating patients with relapsed or refractory B-cell non-Hodgkin's lymphoma, including Waldenstrom's macroglobulinemia.

• No EKG evidence of acute ischemia or active conduction system abnormalities

• Any EKG abnormality must be documented as not medically relevant

• No hypersensitivity to bortezomib, boron, or mannitol

• No known anaphylaxis or immunoglobulin E-mediated hypersensitivity to murine proteins or any component of rituximab (including polysorbate 80 and sodium citrate dehydrate)

• No known infection or exposure to HIV

• At least 10 weeks since prior radioimmunoconjugates or toxin immunoconjugates (e.g., iodine I 131 tositumomab [Bexxar] or ibritumomab tiuxetan [Zevalin])

• More than 2 weeks since prior investigational agent

• No prior bortezomib

• No concurrent systemic corticosteroid at greater than the equivalent dose of 20 mg/day of prednisone, unless for treatment of allergic reactions to CT scan dye

• No concurrent major surgery
