Study of Rituximab Plus High-Dose Chemotherapy Poor Prognosis Non-Hodgkin's Lymphoma

Phase 2

Terminated

• Conditions: Lymphoma, Non-Hodgkin's

• Registration Number: NCT00141700
• Lead Sponsor: University of Michigan Rogel Cancer Center

Brief Summary

This study is being conducted to determine the safety, side effects, and response to a combination of an established high-dose chemotherapy regimen, stem cell support and Rituximab (which is a form of immunotherapy).

Detailed Description

Combination chemotherapy is the standard treatment as initial therapy for aggressive NHL. Standard chemotherapy cures less than 40% of patients. High-dose chemotherapy with stem cell support (or transplant) is showing some positive results in patients with NHL that fail standard chemotherapy. The cure rate of this treatment is only about 50%.

Another treatment option called immunotherapy is being tested in lymphoma patients to see if adding immunotherapy to NHL treatments improves results. Rituximab, a form of immunotherapy, is an antibody (a type of protein) that attacks the CD20 protein found on lymphoma cell, which may result in the death of the lymphoma cell.

The study design is as follows: Patients with poor prognosis NHL receive rituximab as part of the peripheral blood progenitor cell mobilization process and as part of the preparative regimen in combination with high-dose chemotherapy. Granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood progenitor cells (PBPC) are collected and stored. After recovery from high-dose cyclophosphamide, patients are admitted to the hospital for transplant. The preparative regimen consists of rituximab, followed by high-dose chemotherapy.
