Randomization will be open-ended and unstratified. It will be carried out according to a 1:1 ratio and will be balanced by blocks of variable size. Randomization will be performed in Ennov Clinical by connecting to the website. The randomization arm will be assigned automatically during randomization.

Not Applicable | None | Baltimore conditioning regimen: Baltimore-type conditioning with either fludarabine for lymphoid pathologies, or clofarabine for myeloid pathologie is composed of: - fludarabine or clofarabine: 30 mg/m² on D-6/D-5-/D-4/D-3/D-2 - CY (cyclophosphamide): 14.5 mg/kg on D-6/D-5 - Total body irradiation: 2 grays on D-1 (doses of chemotherapy will not exceed a body surface area of 2 m²) - anti-thymoglobulin: ATG 2.5 mg/kg on D-2 Theh, GVH prophylaxis is identical according to the type of conditioning randomized Baltimore or TBF: - MTX: 15 mg/m² at D+1 then 10 mg/m² at D+4/D+6/D+11 - Post transplant CY (PTCY): 50 mg/kg at D+3/D+5 MTX (experimental drug) is a solution for injection containing 5 g MTX in 50 mL. The excipient is sodium chloride 0.9%. MTX is administered by the venous route as a short infusion over 30 minutes. The drug is pre-diluted in 20ml of 0.9% sodium chloride solution. The administration of folinic acid 15 mg/m² is recommended within 6 to 24 hours after MTX injection. In the event of extravasation, administration should be stopped immediately. No dose adjustment is authorized. PTCY (auxiliary drug) is a powder for injectable solution : Cyclophosphamide anhydrous 1000.00 mg as cyclophosphamide 1069.00 mg for one vial. Excipient is sodium chloride. To prepare a ready-to-use isotonic solution, the powder should be dissolved in a 0.9% sodium chloride solution to bring the concentration to 1g per 50ml. If required, it can also be dissolved in Ringer's solution, water for injection or glucose solution. The reconstituted solution should not be stored for longer than 48 hours, and should not exceed a concentration of 2%. The usual route of administration is venous infusion over 1 hour. The drug, reconstituted in 0.9% sodium chloride solution, is introduced into the infusion fluid (isotonic glucose or sodium chloride solution for injection). It is recommended to combine the administration of Uromitexan from 600 mg/m²/d and/or to ensure adequate hydration. In the event of extravasation, administration should be stopped immediately. No dose adjustment is authorized, as it is not intended to include patients with renal impairment (creatinine clearance < 60 ml/min). |

Corticoresistant acute GVH following DLI injection will be excluded
Secondary endpoints 12

- OS at 1 year and last follow-up (survival between day 0 of transplantation and date of death or last follow-up)
- DFS at 1 year and last follow-up (survival from day 0 of transplantation to date of relapse, death or last follow-up)
- GRFS at 1 year and last follow-up (relapse-free survival without grade 3-4 acute GVH or chronic GVH requiring systemic treatment)

- Relapse: any documented disease recurrence at 1 year and last follow-up
- Total donor or mixed chemism at M1, M2, M3, M6, M12. Total donor chimerism = result >95% donor CD3+ and CD34+ cells. Mixed chimerism = result > 5% and < 95% donor CD3+ cells (routine test)
