Pilot Study to Investigate a Steroid Free Immunosuppressive Regimen for Renal Transplant Recipients

Kidney Transplantation Clinical Trial

Official title: Open, Single Centre, Pilot Study to Investigate a Steroid Free Immunosuppressive Regimen for De Novo Renal Transplant Recipients Followed by Randomisation to Calcineurin Inhibitor Containing or Calcineurin Inhibitor Free Immunosuppression

Status Completed

Clinical Trial Summary

The main purpose of this study is to investigate, whether a steroid free immunosuppressive treatment is a valuable alternative in the treatment of de novo kidney transplant recipients and if it is possible to withdraw calcineurin inhibitors after 3 months.

Clinical Trial Description

Protocol synopsis Title An open, single centre, pilot study to investigate a steroid free immunosuppressive regimen for de novo renal transplant recipients followed by a two arm randomization to a calcineurin inhibitor containing and a calcineurin inhibitor free maintenance immunosuppression after three months. Study code Sterfree pilot study Project phase An open, single centre, one arm study followed by a 1:1 randomized, parallel group, comparative study after three months. Study objectives To obtain preliminary information on the efficacy and safety of a rapamycin / sodium-mycophenolate (Myfortic) / tacrolimus regimen in the absence of steroids for the prevention of acute rejection following renal transplantation. To compare a low dose tacrolimus / rapamycin / sodium-mycophenolate (Myfortic) regimen to a rapamycin / sodium-mycophenolate regimen in patients without evidence of acute rejection after three months.

Efficacy:

Primary endpoint

• Plasma creatinine (and creatinine clearance (Cockcroft)) Secondary endpoints

• Incidence of first acute rejections and total number of acute rejections

• Total number of anti-rejection treatments

• Patients successfully withdrawn from calcineurin inhibitor at three months

• Graft survival

• Patient survival

Safety:

• Graft survival

• Patient survival

• Protocol biopsies at 3 months( range: day 75 to 105) and 6 months (range day 165 to 195) sub clinical rejection

• Incidence of first acute biopsy proven rejection and total number of acute rejection episodes

• Total number of anti-rejection treatments

• Patients switched from assigned therapy due to rejection or side effects

• Patients needing steroids because of rejection

• Incidence of selected adverse events: tubulointerstitial nephrotoxicity (TOR inhibitor), leucopenia, thrombocytopenia, elevated fasting blood glucose, dyslipidemia, , electrolyte disturbances, de novo insulin dependency, gastrointestinal disorders (non infectious), neurotoxicity.

• Patients withdrawn due to adverse events

Long term patient follow up Patients will be followed up for graft and patient survival at 12, 24, and 36 months post-transplantation. ;
