Inclusion criteria

Inclusion criteria: • Histologically confirmed (according to the REAL/WHO classification) CD20 positive lymphomas • Patients with a PR or PD • Failed at least one regimen of standard treatment/chemotherapy • Age 18 years or older • World Health Organization (WHO) performance status of 0 to 2 • Absolute Neutrophil Count (ANC) of 1.5 x 109/L or higher • Haemoglobin (Hb) of 9 g/dl or higher • Platelet count of 100 x 109/L or higher • Life expectancy of at least 6 months • Written informed consent obtained according to local guidelines • For patients with = 3 prior cytotoxic treatment regimens and/or patients previously treated with stem cell transplantation, a bone marrow or peripheral blood stem cell harvest is mandatory to rescue unexpected marrow toxicity from the procedure. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 15 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 5

Exclusion criteria

Exclusion criteria: • Patients who have not recovered from the toxic effects of previous treatment • Any other uncontrolled malignancy except non-melanoma skin tumors or stage 0 (in situ) cervical carcinoma • Patients with known HIV positivity • Patients who are positive for HCV, HbsAG or other active infection uncontrolled by treatment • Patients with abnormal liver function: total bilirubin > 2 x ULN or ALT > 3 x ULN • Patients with abnormal renal function: serum creatinine> 2 x ULN • Known anti-chimeric antibody (HACA) reactivity or hypersensitivity to murine antibodies or proteins • Female patients who are pregnant or breast feeding, or adults of reproductive potential not employing an effective method of birth control. (Women of childbearing potential must have a negative serum pregnancy test at study entry) • Concurrent severe and/or uncontrolled medical disease (ie. uncontrolled diabetes, conges¬tive heart failure, myocardial infarction within 6 months of the study, unstable and uncon¬trolled hypertension, chronic renal disease, or active uncontrolled infection), which could compromise participation in the study. • Patients who received 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 psychological illness or condition which could interfere with his ability to understand the requirements of the study (this includes alcoholism/drug addiction) • Patients unwilling or unable to comply with the protocol

Design outcomes

Primary

MeasureTime frame
Main Objective: Evaluation of safety of Zirconium-89 (89Zr)- rituximab chimeric anti-CD20 antibody for PET/CT imaging and dosimetry. Evaluation of safety of Yttrium-90 (90Y)-rituximab chimeric anti-CD20 antibody radioimmunotherapy in patients with B-cell lymphoma who are in partial remission or progressive disease ;Secondary Objective: -Evaluation of the efficacy of 90Y-rituximab treatment by assessment of metabolic response status (by FDG-PET/CT-imaging) and progression-free survival. -Evaluation of the efficacy of 89Zr-rituximab PET/CT-imaging -Evaluation of a voxel based dosimetry model based on PET/CT imaging using 89Zr-rituximab -Diagnostic comparison of 89Zr-rituximab-PET/CT with FDG-PET/CT ;Primary end point(s): Evaluation of safety of Zirconium-89 (89Zr)- rituximab chimeric anti-CD20 antibody for PET/CT imaging and dosimetry. Evaluation of safety of Yttrium-90 (90Y)-rituximab chimeric anti-CD20 antibody radioimmunotherapy in patients with B-cell lymphoma who are in partial remission or progressive disease;Timepoint(s) of evaluation of this end point: Weekly evaluation of the toxicity during first 3 months Evaluation of late toxicity every 3 months during 2 years follow-up

Secondary

MeasureTime frame
Secondary end point(s): -Evaluation of the efficacy of 90Y-rituximab treatment by assessment of metabolic response status (by FDG-PET/CT-imaging) and progression-free survival. -Evaluation of the efficacy of 89Zr-rituximab PET/CT-imaging -Evaluation of a voxel based dosimetry model based on PET/CT imaging using 89Zr-rituximab -Diagnostic comparison of 89Zr-rituximab-PET/CT with FDG-PET/CT -Evaluation of the influence of infusion of unlabelled (cold) rituximab on the distribution of the radio-immunoconjugate;Timepoint(s) of evaluation of this end point: -Response assessment by FDG-PET three months after administration of the treatment - other end points will be evaluated at the end of the study with an interim analysis 2 years after the inclusion of the first patient
