Methotrexate and Glucocorticoids in Treating Patients With Newly Diagnosed Acute Graft-Versus-Host Disease After Donor Stem Cell Transplant

RATIONALE: Methotrexate and glucocorticoid therapy, such as prednisone or methylprednisolone, may be an effective treatment for acute graft-versus-host disease caused by a donor stem cell transplant.

PURPOSE: This phase II trial is studying how well giving methotrexate together with glucocorticoids works in treating patients with newly diagnosed acute graft-versus-host disease after donor stem cell transplant.

OBJECTIVES:

* Determine, within the limits of a phase II study, whether low-dose methotrexate can accelerate withdrawal of glucocorticoids and decrease nonrelapsing mortality in patients with newly diagnosed acute graft-versus-host disease (GVHD) who have undergone nonmyeloablative allogeneic hematopoietic stem cell transplantation (HSCT).
* Determine the tolerability of low-dose methotrexate and glucocorticoids in treating newly diagnosed acute GVHD in these patients.

OUTLINE: This is a cohort study. Patients receive concurrent low-dose methotrexate and a glucocorticoid for treatment of acute graft-versus-host disease (GVHD).

Patients receive the first dose of methotrexate IV ≥ 12 hours before initiation of glucocorticoid treatment (if glucocorticoid treatment has not been initiated) and the second dose 72 hours after dose 1. Patients then receive subsequent doses of methotrexate IV or orally once weekly for up to 1 year\* until resolution of GVHD in the absence of recurrent malignancy, refractory or chronic GVHD, administration of secondary treatment for GVHD, or unacceptable toxicity.

NOTE: \*Treatment with low-dose MTX may continue beyond 1 year at the discretion of the managing physician.

Patients receive glucocorticoid therapy comprising prednisone or methylprednisolone IV twice daily until objective evidence of improvement in GVHD manifestation. Patients with resolved or significantly improved GVHD receive treatment for 10 days followed by an accelerated taper for a total of 72 days of treatment in case of no flare up of GVHD during the glucocorticoid taper. Patients with exacerbation or recurrence of GVHD during the accelerated taper are treated for ≥ 1 week before resuming a less rapid taper. Patients who develop GVHD progression or primary refractory GVHD may receive secondary systemic therapy at the discretion of the managing physician.

After completion of study treatment, patients are followed at 1 year and then annually thereafter.

PROJECTED ACCRUAL: A total of 53 patients will be accrued for this study.

Eligibility Criteria:
DISEASE CHARACTERISTICS:

* Newly diagnosed acute graft-versus-host disease (GVHD)
* Has undergone nonmyeloablative allogeneic hematopoietic stem cell transplantation (HSCT) from an HLA-matched related or unrelated donor ≥ 14 days ago
* Treatment of GVHD with glucocorticoids indicated by 1 of the following criteria:

  * Initial treatment with prednisone or methylprednisolone at 2 mg/kg indicated (in the judgement of attending physician) by any of the following:

    * Severity of GVHD requires hospitalization
    * GVHD manifestations include symptoms other than anorexia, nausea, and vomiting
    * GVHD begins within 2-3 weeks after HSCT
    * GVHD manifestations progress rapidly from 1 day to the next before treatment
  * Initial treatment with prednisone or methylprednisolone at 1 mg/kg did not produce adequate clinical improvement within the first 4 days (in the judgement of attending physician)
* No pleural effusion or ascites (i.e., free-flowing fluid by lateral decubitus views)

  * Mere blunting of costo-phrenic angles on a posterior anterior chest x-ray is not sufficient

* Absolute neutrophil count ≥ 1,500/mm\^3
* Bilirubin ≤ 2 times upper limit of normal (ULN) (unless abnormality attributable to GVHD)
