Bortezomib/Lenalidomide Combination Therapy Evaluated in Relapsed/Refractory Mantle Cell Lymphoma

Editor’s note: This article describes the results of a clinical trial—a research study with volunteer patients. The goal of the trial was to test the effectiveness of a mantle cell lymphoma treatment that combines the drugs bortezomib (Velcade) and lenalidomide (Revlimid). Specifically, the trial tested the treatment for patients whose cancer did not get better after previous treatments or whose cancer returned after treatment. The results of the clinical trial were “disappointing.” The combination treatment was less effective than either drug on its own.

“Although the majority of patients with mantle cell lymphoma respond to initial therapy, the duration of remission is typically short (1.5 to 3 years). Although bortezomib (Velcade) and lenalidomide (Revlimid) as single agents have been associated with response rates as high as 53% in patients with relapsed/refractory disease, Morrison et al reported an overall response rate of almost 40% with combination bortezomib/lenalidomide therapy in an article published in Leukemia & Lymphoma.

“The incidence of mantle cell lymphoma has increased dramatically over the past several decades. The median overall survival is 3 to 6 years with standard chemotherapy approaches, and fewer than 15% of patients are long-term survivors.

“Therefore, researchers continue to investigate newer therapeutic options for these patients. One such approach was the combination of bortezomib and lenalidomide, particularly in patients who experienced relapse from or were refractory to previous treatments. In the phase II CALGB 50501 trial, a team of investigators from the University of Minnesota, Duke University, Dana-Farber Cancer Institute, Ohio State University, Washington University, and Georgetown University attempted to evaluate the feasibility of combination treatment with bortezomib and lenalidomide in patients with relapsed or refractory mantle cell lymphoma.”


Non-Hodgkin’s Lymphoma Center Posts New Study for Effective Treatment of B-cell Non-Hodgkin’s Lymphoma

“Researchers say a drug approved for the treatment of relapsed T-cell Non-Hodgkin’s Lymphoma may help people with indolent B-cell varieties, too. These findings have just been posted on the Non-Hodgkin’s Lymphoma Center at http://nonhodgkinslymphomas.com/drug-may-offer-new-hope-for-follicular-lymphoma/

“Scientists at the Department of Haematology and Oncology at the Nagoya Daini Red Cross Hospital in Japan have concluded that a drug called Zolinza (vorinostat) may improve outcomes for patients fighting indolent B-cell lymphomas like follicular lymphoma and mantle cell lymphoma.”
