This phase II trial studies the side effects and how well sirolimus works as secondary therapy in treating patients with chronic graft-versus-host disease (GVHD) that did not respond to prior treatment. Sirolimus may be an effective treatment for chronic GVHD
PRIMARY OBJECTIVES: I. To assess the safety of sirolimus administered at a dose which provides steady-state, whole blood trough levels of 5-10 ng/mL in patients with chronic GVHD. II. To determine whether administration of sirolimus provides benefit for patients with chronic GVHD that has not responded adequately to previous systemic treatment. OUTLINE: Patients receive sirolimus orally (PO) once daily (QD). Patients continue to receive prednisone and cyclosporine or tacrolimus at the discretion of the managing physician. After completion of study treatment, patients are followed up periodically.

Number of Participants Experiencing Treatment Success
Defined as the absence of any immunosuppressive treatment, including sirolimus, with resolution of all reversible manifestations of chronic GVHD and no additional systemic therapy.
Time frame: Approximately 7 years
Number of Participants Experiencing Treatment Failure
Defined as the initiation of additional systemic therapy, development of bronchiolitis obliterans, or death from causes other than recurrent malignancy during primary treatment for chronic GVHD, whichever occurs first.
Time frame: Approximately 7 years
Number of Participants Needing Additional Systemic Therapy
Includes any intervention intended to control chronic GVHD through an immunosuppressive effect from oral or parenteral administration of any systemic medication not originally given under auspices of this protocol.
Time frame: Approximately 7 years
Number of Participants With Recurrent Malignancy
Defined as clinical or histopathologic evidence demonstrating the presence of any malignancy considered as the indication for transplant. Recurrent malignancy will also be defined as any post-transplant intervention not routinely used to prevent the development of overt recurrence, prompted by laboratory evidence of persisting malignant cells but without clinical or histopathologic evidence of recurrence.
Time frame: Approximately 7 years

Time frame: Approximately 7 years
Proportion With Infections Categorized by Organism
