Informations complémentaires
Schéma : This is a phase III randomized, multicenter, double blinded controlled study. Patients who develop clinically meaningful acute GVHD and who meet all other entry criteria will be randomized 1:1 to receive either corticosteroids and placebo ("standard of care", control arm) or the combination of low-dose MTX with corticosteroids as first-line therapy for acute GVHD (MTX; "experimental arm").

The primary analysis of this hypothesis generation study is to estimate the composite endpoint of GVHD-free and corticosteroids-free survival at 12 months after randomization in both treatment arms. In fact, it is more and more established that such composite endpoint is a clinically very relevant one because it represents ideal recovery from allo-SCT (Stem Cell transplantation) (at 1 year after acute GVHD diagnosis) and a measure of cure without ongoing morbidity.

2 arms:
- Experimental: Methotrexate
5mg/Kg/day methotrexate for 4 weeks then 3 mg/m2 every two weeks for 12 weeks
2mg/kg/day PO prednisone prednisone (or 1.6 mg/kg/day IV methylprednisolone) once daily.
10 mg po or iv lederfolin after each MTX administration
- Placebo Comparator: Placebo
Once a week placebo for 4 weeks then every two weeks for 12 weeks
2 mg/kg/day PO prednisone (or 1.6 mg/kg/day IV methylprednisolone) once daily.
10 mg po or iv lederfolin after each placebo administration

- Women who are of childbearing potential must have a negative serum pregnancy test and agree to use a medically acceptable method of contraception until 6 months after the end of treatment.
- Men with a partner of childbearing potential must agree to use a medically acceptable method of contraception until 6 months after the end of treatment.

Critères de non-inclusion : - Hyper-acute GVHD as defined by the MD Anderson's criteria (Saliba, de Lima et al. 2007)
- Flare of GVHD in a patient already on corticosteroid treatment
- Overlap chronic GVHD as defined by the NIH Consensus Criteria (Jagasia, Greinix et al. 2015)
- MTX given within 7 days of enrollment
- Active uncontrolled infection
- Relapsed/persistent malignancy requiring rapid immune suppression withdrawal
- Acute GVHD after donor lymphocytes infusion (DLI)
- Other systemic drugs for GVHD treatment (including extra-corporeal photopheresis)
- If any prior steroid therapy (for indication other than GVHD), treatment at doses > 0.5 mg/kg/day methyl-prednisolone within 7 days prior to onset of acute GVHD
- Patients who are pregnant, breast feeding, or if sexually active, unwilling to use effective birth control for the duration of the study
- Patient on dialysis
- Patients with veno-occlusive disease of the liver or with significant liver abnormalities who in the judgment of the treating physician cannot receive MTX
- Patients requiring after inclusion in the protocol the continuation of one or more of the following medication: probenecide, trimethoprime (alone or in combination with sulfametoxazole), phenylbutazone or yellow fever vaccine
- Patients with a history of intolerance/allergy to MTX
- Hypersensitivity to the active substance or to any of the excipients
