Detaillierte Beschreibung
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.

Inclusion Criteria:
Biopsy-confirmed diagnosis of clinical extensive chronic GVHD with inadequate response to previous treatment and where secondary systemic therapy is indicated because of
- Clinical progression of signs and symptoms of chronic GVHD in a previously involved organ, or
- Development of signs and symptoms of chronic GVHD in a previously uninvolved organ, or
- Absence of improvement after 3 months of primary treatment, or
- Continued need for treatment with prednisone at doses >= 1.0 mg/kg/day for more than 2 months, without qualification for type of donor, graft or conditioning regimen
- Patient or guardian able and willing to provide informed consent
- Stated willingness to use contraception in women of child-bearing potential (Food and Drug Administration [FDA] requirement)
- Stated willingness of the patient to comply with study procedures and reporting requirements
- Stated willingness of the physician most involved in management of chronic GVHD (the "managing physician,") to comply with study procedures and reporting requirements
Exclusion Criteria:
- Fungal or viral infection with no radiographic evidence of improvement during continued appropriate antimicrobial therapy
- Cytomegalovirus (CMV) antigenemia unresponsive to antiviral therapy
- Active disseminated varicella zoster virus (VZV) infection with persistent non-crusted lesions
- Inability to tolerate oral medications
- Absolute neutrophil count (ANC) < 1500/uL
- Platelet count < 50,000/uL
- Persistent or recurrent malignancy, including histopathologic evidence of myeloma or lymphoma; patients with breakpoint cluster region-abelson (bcr/abl) detected by polymerase chain reaction (PCR) assay as the only evidence of persistent chronic myeloid leukemia may be enrolled
- Pregnancy
- Known history of hypersensitivity to sirolimus

Experimental: Sirolimus
Study participants receive sirolimus added once daily to their baseline combination therapy of prednisone plus either cyclosporine or tacrolimus at the discretion of the managing physician.
Treatment other than cyclosporine (or tacrolimus) and prednisone must be discontinued when administration of sirolimus is started.
Topical therapy, including psoralen and UVA irradiation (PUVA), glucocorticoid creams, topical tacrolimus, oral beclomethasone, topical azathioprine and ophthalmic glucocorticoids may be given at the discretion of the managing physician in consultation with the transplant center.

|
Number of Participants Experiencing Treatment Failure
Zeitfenster: Approximately 7 years

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.

Number of Participants Needing Additional Systemic Therapy
Zeitfenster: Approximately 7 years
|
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.

Approximately 7 years

|
Number of Participants With Recurrent Malignancy
Zeitfenster: Approximately 7 years
|
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.
