In Vivo Purging With Rituximab During Stem Cell Transplantation for Indolent Lymphoma

March 01, 2000

Autologous peripheral blood stem-cell (PBSC) transplantation may play an important role in the treatment of indolent lymphomas, as well as aggressive lymphomas. Concern about the contamination of the autologous graft with lymphoma

In Vivo Purging and Adjuvant Immunotherapy With Rituximab During PBSC Transplant For NHL

March 01, 1999

Contamination of the peripheral blood stem-cell (PBSC) graft with lymphoma and residual disease remaining in the patient after high-dose therapy are two potential causes of relapse after autologous transplantation. Using a tumor-specific monoclonal antibody may be one way to purge the stem-cell graft in vivo and increase the efficacy of the preparative regimen. Rituximab (Rituxan) is an IgG1 kappa chimeric mouse/human antibody containing murine light- and heavy-chain variable regions and human gamma 1 heavy-chain and light-chain constant regions. The antibody reacts specifically with the CD20 antigen found on the surface of malignant and normal B-cells.
