PURPOSE: This phase I/II trial is studying the side effects of sirolimus when given together with tacrolimus and methotrexate and to see how well they work in preventing acute graft-versus-host disease in patients who are undergoing donor stem cell transplantation for hematologic cancer.
- Determine the safety and efficacy of sirolimus when administered with tacrolimus and methotrexate for the prevention of acute graft-versus-host disease (GVHD) in patients with hematological malignancies undergoing hematopoietic stem cell transplantation from unrelated donors.
- Determine the absorption and pharmacokinetics of sirolimus in patients treated with this regimen.
- Correlate sirolimus blood concentration with prevention of GVHD or toxicity in patients treated with this regimen.
- Determine the severity of post-transplantation mucositis in patients treated with this regimen.
OUTLINE: This is a nonrandomized, open-label, pilot study.
Patients receive oral sirolimus once daily on days -3 to 175 and tacrolimus IV continuously beginning on day -3 and continuing until the patient is able to tolerate food and then orally twice daily until day 175. Patients also receive methotrexate IV on days 1, 3, 6, and 11. Treatment continues in the absence of acute graft-vs-host disease or unacceptable toxicity.
Patients are followed for 5 years.
PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 3 years.

Tacrolimus/Sirolimus/Methotrexate Versus Tacrolimus/Methotrexate or Cyclosporine/Mycophenolate Mofetil for GVHD Prophylaxis After Reduced Intensity Allogeneic Stem Cell Transplantation for Patients With Lymphoma
This trial is comparing whether using a drug called sirolimus for graft versus host disease (GVHD) prevention can decrease the chance of the participant's lymphoma relapsing after transpla...
The purpose of this study is to determine if the incidence of Graft vs. Host Disease (GVHD) after non-myeloablative transplantation can be reduced by using a combination of three immune su...

Atopic dermatitis is a chronic inflammatory skin disease. Methotrexate is an off-label systemic agent for treating uncontrolled atopic dermatitis.
A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
Clonal myeloid disorders that possess both dysplastic and proliferative features but are not properly classified as either MYELODYSPLASTIC SYNDROMES or MYELOPROLIFERATIVE DISORDERS.
Members of a family of highly conserved proteins which are all cis-trans peptidyl-prolyl isomerases (PEPTIDYLPROLYL ISOMERASE). They bind the immunosuppressant drugs CYCLOSPORINE; TACROLIMUS and SIROLIMUS. They possess rotamase activity, which is inhibited by the immunosuppressant drugs that bind to them.
A myelodysplastic/myeloproliferative disorder characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to CHRONIC MYELOID LEUKEMIA, but cytogenetically lacking a PHILADELPHIA CHROMOSOME or bcr/abl fusion gene (GENES, ABL).
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
