For at sammenligne effektiviteten af ​​tilsætning af methotrexat (MTX) til den nuværende standard akut graft-versus-vært-sygdom (GVHD) førstelinjebehandling med kortikosteroider (MTX-aGVHD)

15. september 2026 opdateret af: Assistance Publique - Hôpitaux de Paris

Et multicenter randomiseret i dobbeltblindet fase III-studie, der sammenligner standardbehandling alene versus kortikosteroider og lavdosis methotrexat (MTX) til førstelinjebehandling af akut graft-versus-host-sygdom efter allogen stamcelletransplantation

Phase III randomized double-blinded trial designed to compare the efficacy of the addition of MTX to current standard acute GVHD first-line treatment with corticosteroids. The protocol will use a novel endpoint for benchmarking interventions based on a composite primary endpoint of GVHD-free and corticosteroids-free survival.

The primary endpoint of the trial will be the assessment of a composite endpoint of graft-versus-host disease-free and corticosteroids-free survival at 12 months after randomization

Detaljeret beskrivelse

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.

  • First allo-SCT, with any type of donor, stem cell source, GVHD prophylaxis or conditioning regimen
  • Biopsy of acute GVHD target organ is recommended, but not required. Enrollment should not be delayed awaiting biopsy or pathology results

  • 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)

  • 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
