These results were presented here on December 7th at the 45th Annual Meeting of the American Society of Hematology by Morton Coleman, MD, director, Center for Lymphoma and Myeloma, Weill Medical College of Cornell University and the New York Presbyterian Hospital, New York, United States. The regimen is already changing clinical practice, noted Dr. Coleman. Based on prior studies, the regimen was recently approved for the treatment of patients with CD20-positive, follicular non-Hodgkin's lymphoma, with and without transformation, whose disease is refractory to rituximab and who have relapsed following chemotherapy. The goal of the new study was to determine the percentage of patients that can be expected to achieve long-term responses, Dr. Coleman said. The study enrolled 230 patients, with a median age of 52 years, almost all of whom had Stage III/IV disease. At 12 months, 24% of subjects had a durable complete response, defined as complete resolution of radiological abnormalities and disappearance of signs and symptoms related to the disease for at least 12 months. Three-fourths of the patients were still in complete remission after a median follow-up of nearly 5 years, Dr. Coleman said. Patients who relapsed after treatment, or who were refractory to rituximab therapy, and patients who had not received rituximab in the past were equally likely to experience a durable complete response, the study showed.
