Brief Summary:

RATIONALE: High-dose cyclophosphamide may be an effective treatment for acute graft-versus-host disease that did not respond to steroid therapy.

PURPOSE: This phase II trial is studying the side effects, best dose, and how well high-dose cyclophosphamide works in treating patients with acute graft-versus-host disease that did not respond to steroid therapy.

Condition or disease Intervention/treatment Phase
Graft Versus Host Disease Biological: filgrastim Drug: cyclophosphamide Phase 2

Detailed Description:


  • Determine the maximum tolerated dose of high-dose cyclophosphamide in patients with steroid refractory acute graft-versus-host disease.
  • Determine the efficacy of this regimen at 28 days post-treatment in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive high-dose cyclophosphamide once daily for 1-4 days beginning on day 1 and filgrastim (G-CSF) subcutaneously once daily beginning on day 10 and continuing until blood counts recover.

Cohorts of 3-6 patients receive escalating doses of high-dose cyclophosphamide until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

After completion of study treatment, patients are followed weekly for 4 weeks.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 12 participants
Primary Purpose: Supportive Care
Study Start Date : May 2007
Primary Completion Date : January 2013
Study Completion Date : January 2013

Primary Outcome Measures :
  1. Maximum tolerated dose of high-dose cyclophosphamide

    • Steroid refractory GVHD is defined as GVHD that has progressed (increasing in grading) despite 49 hours of treatment with methylprednisolone of ≥ 2.0 mg/kg OR GVHD that has failed to improve (no change in grading stage) despite 4 days of treatment with methylprednisolone of ≥ 2.0 mg/kg
  • Prior allogeneic hematopoietic stem cell transplantation using either bone marrow, peripheral blood stem cells, or cord blood OR prior donor lymphocyte infusion required
  • Evidence of myeloid engraftment
  • No chronic GVHD


  • ECOG performance status (PS) 0-2 OR Karnofsky PS 60-100%
  • ANC > 500/mm³
  • Not pregnant or nursing
  • Fertile patients must use effective contraception
  • Must be geographically accessible
  • No allergy or intolerance to cyclophosphamide or mesna
  • No HIV positivity
  • No mechanical ventilation
  • No active bleeding (excluding gastrointestinal bleeding) or history of hemorrhagic cystitis
  • No other uncontrolled illness including, but not limited to, the following:

    • Ongoing or active infection
    • Medical condition precluding patient from stopping azoles (e.g., fluconazole, itraconazole, or voriconazole) or other adequate antifungal therapy during cyclophosphamide administration
    • Symptomatic congestive heart failure
