Brief summary
Autologous peripheral blood stem cell transplantation combined with high dose chemotherapy is the treatment of choice given to patients with diffuse large-B cell lymphoma (DLBCL) following relapse of the disease. Although many people are cured of their lymphoma with this therapy, the disease comes back in a certain proportion of patients. The purpose of this study is to test the safety and effectiveness of the monoclonal antibody, CT-011, in patients with DLBCL who have received autologous peripheral blood stem cell transplantation. All final eligible patients will receive an IV infusion of CT-011 on Day 1 (30 to 90 days post autologous PBSCT). Treatment will be repeated every 42 days for a total of three courses with treatment visits on Days 1, 43, and 85. Follow-up for safety and clinical outcome will be conducted throughout the study till 18 months post autologous PBSCT. Approximately 70 patients will participate in this study.
Interventions
IV infusion of 1.5 mg/kg of CT-011 on Day 1(60 to 90 days post autologous PBSCT). Treatment was repeated every 42 days for a total of three courses with treatment visits on Days 1, 43, and 85.
