| E.1.2 | Classification code | 10012818 |  
| E.1.2 | Term | Diffuse large B-cell lymphoma |  | 
| E.1.3 | Condition being studied is a rare disease | No | 
| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| Evaluation of efficacy and safety of [90Y]-ibritumomab tiuxetan, as well as assessment of quality of life |  | 
| E.2.2 | Secondary objectives of the trial | 
| An additional secondary endpoint 
 will be health-related quality of life(HRQL) considering that on this way (with introduction of Zevalin)
 
 we reduce the total number of cycles of conventional chemotherapy CHOP from 6-8 to 4.

 mg on day 1, and at least 40 mg/m2/day prednisone on Days 1 to 5 every three weeks) in combination
 
 with rituximab (375 mg/m2);
 
 4. Complete remission (CR), unconfirmed complete remission (CRu), partial response, and nonresponder
 
 according to the International Workshop Response Criteria for NHL described by Cheson
 
 et al (18) afterfour cycles of CHOP21-R. CT scans of the neck, thorax, abdomen, and pelvis and PET
 
 total body must have been performed within 3 weeks after the last dose of the last course of CHOP21-
 
 R;
 
 5. Patients 60-years-of-age or older at time of accrual;
 
 6. WHO performance status (PS) of 0 to 2 within 1 week of accrual;
 
 7. Absolute neutrophil count (ANC) ᄈ 1.5 x 109/L within 1 week of accrual;
 
 8. Hemoglobin (Hgb) ᄈ 10 g/dL within 1 week of accrual;
 
 9. Platelets. 150 x 109/L within 1 week of accrual.
 
 10. Life expectancy of 3 months or longer
 
 11. Written informed consent obtained according to local guidelines
 |  | 
| E.4 | Principal exclusion criteria | 
| Presence of any other malignancy or history of prior malignancy except non-melanoma skin tumors or 
 stage 0 (in situ) cervical carcinoma;
 
 2. Prior radioimmunotherapy, radiation therapy, or any other NHL therapy;
 
 3. Presence of gastric, central nervous system (CNS), or testicular lymphoma at first diagnosis;
 
 4. Histological transformation of low-grade NHL;
 
 5. Known seropositivity for hepatitis C virus (HCV) or hepatitis B surface antigen (HbsAg);
 
 6. Known history of HIV infection;
 
 7. Abnormal liver function: total bilirubin > 1.5 x ULN or ALT > 2.5 x ULN within 1 week of accrual;
 
 8. Abnormal renal function: serum creatinine > 2.0 x ULN within 1 week of accrual;
 
 9. Nonrecovery from the toxic effects of CHOP21-R therapy;
 
 10. Known hypersensitivity to murine or chimeric antibodies or proteins;
 
 11. G-CSF or GM-CSF therapy within two weeks (or four weeks if pegylated) prior to screening
 
 laboratory sampling;
 
 12. Concurrent severe and/or uncontrolled medical disease (e.g., uncontrolled diabetes, congestive heart
 
 failure, myocardial infarction within 6 months of study, unstable anduncontrolled hypertension,
 
 chronic renal disease, or active uncontrolled infection) which could compromise participation in the
 
 study;
 
 13. Treatment with investigational drugs less than 4 weeks before the planned Day 1 or nonrecovery from
 
 the toxic effects of such therapy;
 
 14. Surgery less than 4 weeks before the planned Day 1 or nonrecovery from the side effects of such
 
 surgery;
 
 15. Concurrent corticosteroid use for any reason except as premedication in case of known or suspected
 
 allergies to contrast media or as premedication for potential side effects of rituximab treatment;
 
 16. Unwillingness or inability to comply with the protocol.
