Thirty adults with leukemia or lymphoma undergoing marrow transplantation from HLA-compatible unrelated donors received tacrolimus (FK506), a new immunosuppressive macrolide lactone, and minidose methotrexate to prevent acute graft-versus-host disease (GVHD). The group had a median age of 36 years (range 21 to 49 years). Twenty-four patients had advanced(More)
We report the results of a phase III open-label, randomized, multicenter trial comparing tacrolimus/methotrexate to cyclosporine/methotrexate for graft-versus-host disease (GVHD) prophylaxis after HLA-identical sibling marrow transplantation in patients with hematologic malignancy. The primary objective of this study was to compare the incidence of moderate(More)
The safety and potential efficacy of FK506 in combination with a short course of methotrexate (MTX) for the prevention of acute graft-versus-host disease (GVHD) after marrow transplantation from HLA-matched unrelated donors was evaluated in a single-arm Phase II study conducted at two centers. Forty-three patients, 15 to 54 (median 41) years of age, were(More)
A randomized clinical trial comparing tacrolimus with cyclosporine, both with short-course methotrexate, as prophylaxis against graft-vs.-host disease (GVHD) in allogeneic HLA-matched sibling bone marrow transplant patients was conducted. Cyclosporine was dosed to achieve a target concentration range between 150 and 450 ng/mL during the first 8 weeks after(More)
BACKGROUND Attention deficit hyperactivity disorder is a behavioral syndrome of childhood characterized by inattention, hyperactivity and impulsivity. There were many etiological theories showed dysfunction of some brain areas that are implicated in inhibition of responses and functions of the brain. Minerals like zinc, ferritin, magnesium and copper may(More)
Tacrolimus has proved effective for preventing acute graft-vs.-host disease (GVHD) after unrelated donor marrow transplantation, but the therapeutic window is apparently narrow. Therapeutic drug monitoring could potentially be used to guide dose modifications, but the optimal target range of tacrolimus blood concentrations is unknown. We determined whether(More)
Initial studies of FK506 combined with methotrexate (MTX) in patients receiving unrelated donor BMT have demonstrated a possible-decrease in the incidence of severe GVHD but high rates of severe stomatitis and nephrotoxicity. With this background, we undertook a pilot study evaluating FK506 in combination with a lower than usual dose of MTX in an attempt to(More)
FK506 (Tacrolimus) is an immunosuppressive drug that blocks the activation of antigen-specific T lymphocytes, a major component in the pathogenesis of graft-versus-host disease (GVHD). This study was designed to obtain first estimates of the safety and efficacy of FK506 monotherapy in the prevention of GVHD following HLA-identical sibling marrow(More)
The pharmacokinetics of tacrolimus following its administration as monotherapy or in combination with corticosteroids or methotrexate to 31 BMT patients are presented. All patients received i.v. tacrolimus initially and were subsequently switched to p.o. dosing. Patients received methotrexate by i.v. bolus on post-transplantation days 1, 3, 6 and 11.(More)
A phase HI comparative trial of tacrolimus- vs. cyclosporine-based graft-vs.-host disease (GVHD) prophylaxis for human leukocyte antigen (HLA)-identical sibling bone marrow transplantation showed less GVHD but poorer survival in the tacrolimus arm. To test the comparability of the two treatment arms with respect to baseline survival prognosis, a matched(More)
