Brief summary
The purpose of this study is to improve the outcome of elderly patients with CD20-Aggressive B-Cell Lymphoma and to reduce the toxicity of standard used Immuno-Chemotherapy by using an optimised schedule of the monoclonal antibody Rituximab, substituting conventional by Liposomal Vincristine and by a PET-guided reduction of therapy in Combination with Vitamin D Substitution.
Detailed description
Primary objective of study: OPTIMAL\>60 Less Favourable Patients with less favourable prognosis: To test whether progression-free survival (PFS) can be improved by substituting conventional by liposomal vincristine; To test whether PFS can be improved by 12 optimised applications instead of 8 2-week applications of rituximab. OPTIMAL\>60 Favourable: Patients with favourable prognosis: Comparison of neurotoxicity of conventional and liposomal vincristine; Determination of PFS for the treatment strategy of reducing treatment in patients with negative FDG-PET after 4 x R-CHOP/CHLIP-14 (PET-4) and comparison with the corresponding patient population in RICOVER-60. Secondary objectives: OPTIMAL\>60 Favourable and OPTIMAL\>60 Less Favourable: Comparison of the prognostic value of a pre-treatment FDG-PET (PET-0) with conventional CT/MRT. Prospective evaluation on the role of (metabolic) tumor volume to confirm or refuse the hypothesis that optimized rituximab should improve the outcome of patients with a high (metabolic) tumor volume more than that of patients with low MTV and to analyse the substitution of conventional vincristine by liposomal. • Estimation of the vincristine-related neurotoxicity (OPTIMAL\>60 Less Favourable only, since vincristine related neurotoxicity is primary objective of the study in favourable patients) and other toxicities (all patients). Determination of the therapeutic efficacy of a vitamin D substitution. Comparison of the FDG-PET-based individualised treatment strategy in OPTIMAL\>60 with the fixed (pre-defined) treatment strategy in RICOVER\>60.

Comparison of the vincristine related neurotoxicity before and after amendment 4. Comparison of CNS events before and after amendment 4. Comparison of the Cheson, Lugano and RECIL response criteria. Prospective evaluation of the improvement of the prognostic value of ECOG performance status during prephase treatment. Prospective evaluation of reference pathology biomarkes. Prospective evaluation of circulating tumor DNA (ctDNA), correlation and comparison with PET. Prospective evaluation of the role of 2 additional cycles of CHOP/CHLIP-14 and involved node radiotherapy in PET-positive patients after 4xR-CHOP/CHLIP-14 in favourable patients. Evaluation of the role of radiotherapy to PET-positive bulky disease patients after 6xR-CHOP/CHLIP-14 in less favourable patients.

Investigation of specific concomitant medication and possible impact on outcome. Investigation of the efficacy of the modified mandatory infectious prophylaxis OPTIMAL compared to the RICOVER trial with a focus on mandatory chinolon prophylaxis.

Inclusion criteria
1. Age: 61-80 years 2. All risk groups (IPI 1-5) 3. Diagnosis of aggressive CD20+ B-NHL, based on an excisional biopsy of a lymph node or on an appropriate sample of a lymph node or of an extranodal involvement. It will be possible to treat the following entities in this study as defined by the new WHO classification of 200870: B-NHL: * Foll. lymphoma grade IIIb * DLBCL, not otherwise specified (NOS) * common morphologic variants: * centroblastic * immunoblastic * anaplastic * rare morphologic variants * DLBCL subtypes/entities: * T-cell/histiocyte-rich large B-cell lymphoma * primary cutaneous DLBCL, leg type * EBV-pos. DLBCL of the elderly * DLBCL associated with chronic inflammation * primary mediastinal (thymic) LBCL * intravascular large B-cell-lymphoma * ALK-positive large B-cell-lymphoma * plasmoblastic lymphoma * primary effusion lymphoma * transformed indolent lymphoma secondary or simultaneous high grade B-cell-lymphoma * B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma * B-cell lymphoma, unclassifiable, with features intermediate between DLCBL and Hodgkin lymphoma 4. Performance status ECOG 0 - 2 after prephase treatment. The performance status of each patient must be assessed before the initiation and after the end of prephase treatment which, as experience has shown, can result in a significant improvement of the patient's performance status. The pre-treatment performance status which can range from ECOG 0 to ECOG 4 must be documented in the Staging CRF (see ISF); the performance status after the prephase treatment must be documented in the respective Prephase Treatment CRF (PT form: see ISF). A definition of the performance status is provided in Appendix 28.10. 5. Written informed consent of the patient 6. Contract of participation signed by the study centre and sponsor

Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | 9 years | OPTIMAL\>60 Less Favourable: To test the effects of substitution of conventional by liposomal vincristine and of a 2-week applications of 8x rituximab by an optimised application of 12 x rituximab stratified log rank tests will be performed for each question (stratified for IPI-factors). Proportional hazard models will be used to investigate treatment interaction and to obtain estimates for the single treatment effects (HR) adjusting for the IPI-factors. OPTIMAL\>60 Favourable Grade of neurotoxicity will be estimated and indicated with a 95% confidence interval (CI) separated to each type of vincristine. To investigate the 3-year PFS with 95% CI the Kaplan-Meier estimator will be used. |

| for efficacy: CR-rate, PR-rate, rate of primary progressions, relapse rate, EFS and OS; rate and CTC grades of PNP. Prognostic value of the FDG-PET derived imaging biomarkers for lymphoma load: SUV, MTV, TLG. | 9 years | Secondary endpoints: To analyze how (i. e. in which direction) and how often a pre-treatment FDG-PET-based assignment (PET-0) would have affected the assignment of a patient to a different stage, IPI risk group or treatment, respectively. The different FDG-PET derived imaging biomarkers for lymphoma load (SUV, MTV, TLG) will be analyzed for their relationship with CR-rate, PR-rate, rate of primary progressions, relapse rate, EFS, PFS and OS. To compare the efficacy and side effects of the (post-induction therapy FDG-PET-based) individualised treatment strategy in OPTIMAL\>60 with the fixed (pre-defined) treatment strategy in RICOVER-60. Rates and grades of polyneuropathy will be determined according to CTC-v4.03. Comparison of the patients without vitamin-D-substitution with patients receiving a vitamin-D-substitution. |
