Brief Summary:
In this study the investigators are proposing to treat patients with steroid-refractory Graft-versus-host Disease (GVHD) in a manner designed to promote CD4+CD25+FoxP3+ Tregs. The profound immune suppression which follows the most common salvage treatment for GVHD have unfortunately lead to very poor outcomes because of high infection rates. A more targeted approach based on the promotion and stabilization of Tregs is hoped to allow GVHD control without the profound immunosuppression usually seen. High-dose cyclophosphamide and sirolimus have been successfully used for the prevention of GVHD and have shown to enhance the Tregs subpopulation. The addition of low dose IL-2 and a demethylating agent such as azacitidine will also be studied in an attempt to promote and stabilize the FoxP3 expression of Tregs.

Primary Purpose: Treatment
Official Title: Phase I- II Study of in Vivo Regulatory T Cell Enhancement With Cyclophosphamide and Sirolimus With or Without Vidaza (Azacitidine) for the Treatment of Steroid-refractory Acute Graft-versus-host Disease
Study Start Date : August 2011
Actual Primary Completion Date : March 2012
Actual Study Completion Date : July 2012

Arm Intervention/treatment
Experimental: Cyclophosphamide and Sirolimus
Patients will be treated in sequential cohorts of 5. In cohort A, the first 5 enrolled patients will be receive cyclophosphamide and sirolimus only
Drug: Cyclophospahmide and Sirolimus

On the first day of treatment, cyclophosphamide will be administered at a dose of 4g/m2 IV x 1 dose. Patients who are >40% above ideal weight will be dosed based on adjusted weight and adjusted BSA.

One day after the administration of cyclophosphamide, patients will receive sirolimus 6 mg PO x 1 and on the following day will start sirolimus at a dose of 2 mg PO daily.

Other Name: Cytoxan

Experimental: Low dose IL-2 with Cytoxan + Sirolimus Drug: Low dose IL-2, Cyclophosphamide and Sirolimus

Patients in treatment arm B will be receiving low-dose IL-2 in conjunction with the cyclophosphamide and sirolimus.

IL-2 will be administered at a dose of 0.5E6 IU/m2 SQ daily x 8 weeks followed by 4 weeks off, starting 14 days after the cyclophosphamide.

Other Names:
  • Interleukin-2
  • Cytoxan

Experimental: Low dose IL-2, Vidaza, Cytoxan & Sirolimus Drug: Low dose IL-2, low dose Vidaza, cyclophosphamide & Sirolimus

Patients in treatment arm C will be receiving low-dose azacitidine (Vidaza). The Vidaza will be initiated between day 27 and 32 following the cyclophosphamide.

The dose administered will be 10 mg SQ daily for 5 days followed by 3 weeks off.

Other Names:
  • Interleukin-2
  • Azactidine
  • Cytoxan

Primary Outcome Measures :
  1. The primary objective of this study is to determine the response rate of patients treated steroid-refractory GVHD using cyclophospahmide and sirolimus combined with 3 variations of low-dose IL 2 and low-dose Vidaza. [ Time Frame: 28 days to 100 days post transplant ]
