Trial Title: New Combination of Chemoimmunotherapy for Systemic B-cell Lymphoma With Central Nervous System Involvement

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE2
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~1. Histologically confirmed diagnosis of diffuse large B-cell lymphoma~2. CNS involvement (brain, meninges, cranial nerves, eyes and/or spinal cord) at diagnosis (concomitant to extra-CNS disease) or relapse after conventional chemo(-immuno)therapy~3. Diagnosis of CNS involvement either by brain biopsy or CSF cytology examination. Neuroimaging alone is acceptable when stereotactic biopsy is formally contraindicated or when the disease has been previously histologically documented in other areas and the CNS localization is concomitant with a diffuse progression of systemic disease.~4. No previous treatment with high-dose methotrexate-based chemotherapy and/or brain irradiation. One-two courses of R-CHOP combination as upfront therapy are admitted in patients with large amount and/or extensive extra-CNS disease that could condition prognosis in an early phase of treatment. Local investigator decides if initial R-CHOP is needed based on patient's conditions~5. Age 18-70 years~6. ECOG performance status 0-3~7. Adequate bone marrow (Platelets count ≥100.000/mm3, hemoglobin ≥9 g/dL, neutrophils count≥1.500/mm3), renal (creatinine clearance ≥60 mL/min), cardiac (LVEF ≥50%), and hepatic function (total serum bilirubine ≤3 mg/dL, AST/ALT and GGT ≤2.5 per upper normal limit value), unless the abnormality is due to lymphoma infiltration~8. Absence of HIV infection and of detectable HCV-RNA and/or HBsAg and/or HBV-DNA~9. No concurrent malignancies. Previous malignancies are accepted if surgically cured or if there was no evidence of disease in the last 3 years at a regular follow-up~10. Absence of any familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule~11. Female patients must be non-pregnant and non-lactating. Sexually active patients of childbearing potential must implement adequate contraceptive measures during study participation~12. No treatment with other experimental drugs within the 6 weeks previous to enrolment~13. Given written informed consent prior to any study specific procedures, with the understanding that the patient has the right to withdraw from the study at any time, without any prejudice. Informed consent signed by a patient's guardian is acceptable if the patient is not able to decide inclusion in the study due to cognitive impairment~Exclusion Criteria:~1. Other lymphoma categories other than diffuse large B-cell lymphoma. In particular, patients with primary mediastinal lymphoma, intravascular large B-cell lymphoma or leg-type large B-cell lymphoma are excluded.~2. Patients with positive flow cytometry examination of the CSF, but negative results in CSF conventional cytology, and without any other evidence of CNS disease.~3. Patients with exclusive CNS disease at presentation (primary CNS lymphoma) are excluded~4. Previous treatment with support of autologous or allogeneic stem cells/bone marrow transplantation.~5. Symptomatic coronary artery disease, cardiac arrhythmias not well controlled with medication or myocardial infarction within the last 6 months (New York Heart Association Class III or IV heart disease)~6. Any other serious medical condition which could impair the ability of the patient to participate in the trial.

Study Arms:
- MATRIX - R-ICE - Conditioning and ASCT (Type: EXPERIMENTAL): MATRIX (courses 1,2,3): Rituximab 375 mg/m2 d0/Methotrexate 3.5 g/m2 d1/Cytarabine 2 g/m2 d2 \& d3/Thiotepa 30 mg/m2 d4/Liposomial Cytarabine 50 mg\* d5~R-ICE (courses 4,5,6):Rituximab 375 mg/m2 d1/Etoposide 100 mg/m2 d1,d2, d3/Ifosfamide 5 g/m2 d2/Carboplatin 5 AUC d2/Liposomial Cytarabine 50 mg\* d4~\*If liposomal cytarabine is not available, standard intrathecal chemotherapy with methotrexate 10 mg + cytarabine 40 mg + hydrocortisone 50 mg can be administered. Oral steroids are suggested for 2-3 days after intrathecal liposomial cytarabine delivery to prevent chemical or aseptic meningitis/ arachnoiditis.~Conditioning and ASCT: BCNU (carmustine)\*\* 400 mg/m2 d-6/Thiotepa 5 mg/kg d-5 \& d-4 ASCT: 5 x 106 CD34+cells/kg d0~\*\*In case of BCNU unavailability, the recommended conditioning regimen (Phase IV) is: Thiotepa 5 mg/kg d-6 \& d-5/Busulfan 3.2 mg/kg d-4,d -3,d-2/Clonazepam 2 mg/d d-4,d -3,d-2 ASCT: 5 x 106 CD34+cells/kg d0
