Primary Outcome Measures:
  • DFS [ Time Frame: 24 months after inclusion ] [ Designated as safety issue: Yes ]
    DFS is defined as the probability to be alive and in remission

Secondary Outcome Measures:
  • HSCT [ Time Frame: 24 months after inclusion ] [ Designated as safety issue: Yes ]
    • Rate of pre-graft splenectomy
    • Co-morbidity score defined by Sorror et al before RUXOLITINIB and after 4-month treatment just before transplantation
    • Post-graft haematological recovery: time to neutrophil engraftment, platelet and red blood cells transfusion independency
    • Acute GVHD grade II-IV incidence
    • Chronic GVHD incidence
    • Overall survival, disease-free survival, non-relapse mortality
    • JAK2V617E allele burden and status at registration, 3, 7, 16 months after inclusion (centralization)

  • PATIENTS CARACTERISTICS [ Time Frame: 24 months after inclusion ] [ Designated as safety issue: Yes ]

    Patients with and without donor

    • Rate of patients with donor who benefit from a transplantation:
    • Comorbidity score at registration and after 3 months
    • Platelet and red blood cells transfusion independency
    • Performance status evolution (ECOG)
    • General symptoms related to myelofibrosis (questionnaire MF SAF)
    • Comparison of haematological response in patients with or without donor
    • Spleen size evolution
    • Comparison of quality of life in patients with and without (questionnaire EORTC)
    • Comparison of overall survival in patients with and without donor
    • Incidence of severe infections
    • Cytokine measure at registration, 3, and 7 months after inclusion (centralization)
    • MPL JAK status (at registration, centralization

Detailed Description:
JAK2 inhibitor RUXOLITINIB before allogeneic hematopoietic stem cell transplantation (HSCT) in patients with primary or secondary myelofibrosis

Ages Eligible for Study:   18 Years to 69 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Age between 18 and 69 years
  • No comorbidity contraindicating the transplantation :

    • Severe respiratory failure defined as dyspnea grade III or more
    • Severe cardiac failure defined as EF < or = 30%
    • Severe renal failure defined as creatinine clearance < 30 ml/min or dialysis

    • Major alteration of performance status defined as ECOG > 2
    • Severe liver disease defined as a cirrhosis or bilirubin > 2 x ULN, or AST/ALT > 5 x ULN
  • Primary or secondary myelofibrosis diagnosed according to WHO definition (Tefferi, et al 2007)
  • Palpable splenomegaly or splenomegaly measured by any imagery (maximum size> 15 cm by ultrasound scan, Magnetic Resonance Imaging or computer tomography)
  • Disease if intermediate or high risk according to published criteria and summarized as follows:

At least one criterion among the following:

  • Peripheral blastosis > 1% observed at least twice
  • Thrombocytopenia < 100 G/L (unrelated to treatment toxicity)

Exclusion Criteria:

  • Previous treatment with JAK2 inhibitor
  • Thrombopenia < 50 G/L
  • Comorbidities contraindicating the transplantation
  • Comorbidity score Sorror > 3
  • Pregnant or lactating women
