To evaluate if rapamune + tacrolimus immunosuppressive prophylaxis is better than the established therapy using cyclosporine and methotrexate, a Nordic prospective multicenter randomized study will be performed. Patients will be randomized to treatment with rapamune combined with tacrolimus, or the established therapy using cyclosporine and methotrexate.
Primary endpoint The primary endpoint is grade II-IV acute GVHD in the two groups. GVHD is diagnosed clinically and graded from 0 to IV. The diagnosis is clinical and biopsies from skin, liver and gut is used according to the routines at each participating center.
Other study parameters
1. Time to neutrophils >0.5 x 109/L.
2. Time to platelets >20 x 109/L and 50 x 109/L.
3. Platelet level 30 days after transplant.
4. Transfusion requirements of platelets, erythrocytes, granulocyte transfusions during the first 30 days.
5. Non-engraftment (graft failure/rejection).
6. Grade of acute GVHD.
7. Incidence of chronic graft-versus-host disease graded as limited or extensive and mild, moderate and severe.
8. Transplant-related mortality.
9. Probability of relapse in patients with haematological malignancies.
11. Relapse-free survival.
12. Infections by bacteria, virus and fungi. Cytomegalovirus reactivation is also followed by PCR.
13. Side-effects. Side-effects regarding hematopoiesis, liver test, renal function, cardiac function, neurology, endocrinology, etc., are taken from the patients' charts. These parameters are followed regularly after transplantation.
Inclusion criteria Chronic myeloid leukemia (CML) in 1st or 2nd chronic phase, acute myeloid leukemia (AML) in complete remission, acute lymphoblastic leukemia (ALL) in complete remission, myelodysplastic syndrome, chronic lymphocytic leukemia, lymphoma, non-malignant disorders, severe aplastic anemia, hemoglobinopathies and metabolic disorders

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...
To compare the effectiveness of Tacrolimus and Rapamycin to Tacrolimus and Methotrexate in the prevention of severe graft-versus-host-disease.
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...

Tacrolimus and Methotrexate With or Without Sirolimus in Preventing Graft-Versus-Host Disease in Young Patients Undergoing Donor Stem Cell Transplant for Acute Lymphoblastic Leukemia in Complete Remission
RATIONALE: Giving chemotherapy, such as thiotepa and cyclophosphamide, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also helps s...
We conducted a phase 2 study in which patients undergoing allogeneic hematopoietic stem cell transplantation received Tocilizumab in addition to standard immune suppression with tacrolimus and methotr...

In transplantation medicine calcineurin inhibitors (CNI) still represent the backbone of immunosuppressive therapy. The nephrotoxic potential of the CNI Cyclosporine A (CsA) and Tacrolimus (FK506) is ...
This study aimed to clarify the mechanisms and assess the characteristics of the chronic graft-versus-host disease (cGVHD) fibrosis in the lacrimal gland (LG) of mice.
An immunological attack mounted by a graft against the host because of tissue incompatibility when immunologically competent cells are transplanted to an immunologically incompetent host; the resulting clinical picture is that of GRAFT VS HOST DISEASE.
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.
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 family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
