Study summary

Three recent prospective "transplant/no transplant" studies concluded to an advantage of OS with transplantation in patients with high or intermediate-2 IPSS risk (not significant in Kröger's study). No prospective randomized trial has assessed the pre-transplant therapy in MDS patients yet but some information can be extracted from these 3 recent studies. In the French study (n=162), 72% patients with a donor received HSCT, previously treated by hypomethylating agent (HMA) in 71% of them. There was a trend to a better survival in patients achieving a complete remission with pre-graft therapy (HR: 0.55, p=0.088) and higher risk of death in unresponsiveness patients transformed into AML (HR: 2.36, p=0.008). In Nakamura's study (n=384), 83% of patients with a donor were transplanted, previously treated by HMA in 68%2. The multivariable Cox model for Overall Survival (OS) and Leukemia-free survival showed an excess risk in patients treated by HMA. Moreover, responders still have a higher risk of mortality as compared to patients who did not receive any pre-graft therapy (HR: 2.417, p=0.0054). In the German study, the aim was to initiate azacytidine at inclusion and to transplant patients after 4 cycles if a donor was identified1. Among 170 registered patients, 162 initiated 5-aza but 36% of them were "lost during this pre-graft therapy" before allocation to "donor" or "no-donor" arm, for different reasons including death (n=12). After 4 cycles of 5-aza, 79/81 patients "donor arm" were transplanted. The multivariable analysis showed remission status did not influence OS. Those 3 previous clinical trials thus suggest that a substantial number of patients planned for transplantation are not transplanted nowadays while no evidence of HMA benefit before HSCT has been clearly identified. This phase 2 study aim to assess the feasibility of upfront HSCT in patients with high risk MDS in order to increase the probability to be transplanted and to achieve a subsequent remission and better survival.

Inclusion criteria

  • Age ≥ 50 and ≤ 70 years
  • An HLA (Human Leukocyte Antigen) matched sibling donor or familial haplo-identical donor has been identified
  • The disease fulfills at least one of the following criteria:

    • Intermediate-2 or high risk according to classical International Prognostic Scoring System (IPSS)
    • Intermediate-1 risk if marrow fibrosis > grade I or poor risk cytogenetics according to R IPSS or classified high or very high risk according to Revised International Prognostic Scoring System (R IPSS) or if the MDS is therapy-related neoplasm
  • Usual criteria for Hematopoietic Stem Cell Transplantation (HSCT):

    • Eastern Cooperative Oncology Group Score (ECOG) ≤ 2
    • No severe and uncontrolled infection
    • Cardiac function compatible with high dose of cyclophosphamide Left Ventricular Function (LVF) > 50%
    • Adequate organ function: ASAT and ALAT ≤ 2.5N, total bilirubin ≤ 2N, creatinine clearance ≥ 30 ml/min (according to Cockroft formula)
  • In case of transplantation with a haploidentical donor, absence of donor specific antibody (DSA) detected in the patient with a MFI >1000 (antibodies directed towards the distinct haplotype between donor and recipient)
  • Contraception methods must be prescribed for women of childbearing age during all the study. If cyclophosphamide is used, effective contraceptive methods for men during all their participation in the study
  • With health insurance coverage
  • With a written informed consent signed

Exclusion criteria

Exclusion Criteria:

  • Marrow blast > 15% at time of inclusion
  • MDS with excess blast >10% and NPM1 mutation or a recurrent genetic abnormality related to Acute Myeloid Leukemia (AML) (WHO 2022)
  • Chemotherapy (AML like intensive chemotherapy or demethylating agent) to treat MDS at the current stage
  • Disponibility of an unrelated donor 10/10 (MUD) in absence of geno-identical donor
  • Patient with uncontrolled infection
  • Cancer in the last 5 years (except basal cell carcinoma of the skin or "in situ" carcinoma of the cervix
  • Renal failure with creatinine clearance \<30ml / min (according to Cockroft formula)
  • With contraindications to treatments used during the research
  • Uncontrolled coronary insufficiency, recent myocardial infarction \<6 month, current manifestations of heart failure, uncontrolled cardiac rhythm disorders, ventricular ejection fraction \<50%
  • With heart failure according to NYHA (II or more)
  • Patient with seropositivity for HIV or HTLV-1 or active hepatitis B or C defined by a positive PCR Hepatitis B Virus or Hepatitis C Virus
  • Yellow fever vaccine or any alive vaccine within 2 months before transplantation
  • Pregnancy (β-HCG positive) or breast-feeding
  • Who have any debilitating medical or psychiatric illness, which would preclude giving well understand informed consent or optimal treatment and follow-up
  • Under protection by law (tutorship or curatorship)
