About

This is prospective randomized open single center clinical study to compare effect of sirolimus vs mycophenolate tacrolimus based protocol on pancreas and kidney graft survival in simultaneous pancreas and kidney recipients.

Full description

MTOR (mammalian target of rapamycin) inhibitors represent group of immunosuppressive drugs with mechanism of T-cell blockade complementary to calcineurin inhibitors. The investigators presume that combination of sirolimus with tacrolimus will result in better survival of pancreatic and kidney grafts in simultaneous pancreas and kidney transplantations.

The study is proposed as a single-center extension of EUROSPK 002 trial originally started in 2004 by the EUROSPK Study Group. Recruitment of recipients started in 2004 with approval of EUROSPK 002. The patient recruitment has continued in a single center (Institute for Clinical and Experimental Medicine in Prague, Czech Republic) using the same inclusion and exclusion criteria. The recipients of primary kidney and pancreas transplantation have been randomized into 2 arms.

In the intervention arm sirolimus is added to protocol at a dose of 5 mg immediately before transplantation, the dose is adjusted to maintained trough sirolimus trough levels between 5-10ng/ml.
In the control arm mycophenolate mofetil was added to tacrolimus. Starting with 1g before transplantation, the dose has been increased to 1g bid afterwards.

Induction protocol at day 0. consists of ATG (antithymocyte globulin)induction 8mg/kg , Tacrolimus 0.05mg/kg, Methylprednisolone 125mg. Dosing of tacrolimus has been adjusted to maintain trough levels between 5-10ng/ml. ATG was administered at 3mg/kg on days 1.-3. Steroids have been gradually tapered from a dose of 20 mg prednison orally and withdrawn by 6w after transplantation.
