Radioimmunotherapy With 90Y-ibritumomab Tiuxetan as Part of a Dose Reduced Conditioning Regimen for Allogeneic Hematopoietic Cell Transplantation for the Treatment of Non-Hodgkin Lymphoma

• Status: Completed
• Trial end date: 2011-07-01
• Target enrollment: 0
• Participant gender: All

Summary

The study evaluates the additional use of radioimmunotherapy with a 90-Yttrium labeled monoclonal antibody targeting lymphoma cells in two dose reduced conditioning regimens for allogeneic hematopoietic cell transplantation from human leukocyte antigen (HLA)-identical donors. Radioimmunotherapy should allow an increased anti-lymphoma effect of the conditioning while the allogeneic grafts may confer potent graft versus lymphoma effects and rescue from potential hematopoietic side effects of the radioimmunotherapy. The study evaluates the feasibility and toxicity of such approach and will also analyze disease response and survival of the patients treated.

The following entities of lymphomas can be included in Arm A of the protocol:

Arm A:

• Small lymphocytic lymphoma (SLL/CLL)

• Mantle cell lymphoma (MCL)

• Follicular lymphoma Grade 1-2

• Marginal zone lymphoma (MZL)

• HLA-identical related or unrelated donor

• CD20+ lymphoma cells on biopsy or peripheral blood

• Disease stage at inclusion: CR, PR or SD

Exclusion Criteria:

• Patients with pleural effusion or ascites

• Concurrent severe and/or uncontrolled medical disease (e.g. uncontrolled diabetes, congestive heart failure, myocardial infarction within 6 months prior to the study, unstable and uncontrolled hypertension, chronic renal disease, or active uncontrolled infection) which could compromise participation in the study

• Patients who received any investigational drugs less than 4 weeks before entry in this study or who have not as yet recovered from the toxic effects of such therapy

• Patients who underwent surgery within 4 weeks of entering the study or patients who have not as yet recovered from the side-effects of such treatment

• Patients with a history of psychiatric illness or condition which could interfere with their ability to understand the requirements of the study (this includes alcoholism/drug addiction)

• Patients unwilling or unable to comply with the protocol

• Unable to give informed consent

• Enrollment in another trial interfering with the endpoints of this study
