Detailed Description
Simultaneous pancreas-kidney (SPK) transplantation is a recommended treatment option for type 1-diabetic patients suffering from end-stage kidney disease.1 Major factors contributing to the success of SPK transplantation include improvements in surgical technique and the provision of effective immunosuppressive strategies heralded by the introduction of the calcineurin inhibitors.2 According to the International Pancreas Transplant Registry (IPTR), since the mid-1990s, the most popular maintenance therapy has been with Tacrolimus and Mycophenolate Mofetil (MMF), utilized in approximately 66% of SPK transplanted recipients. Since 1994, the proportion of pancreas recipients who received induction therapy has exceeded 70% and by that means induction therapy is used with greatest frequency for pancreas recipients than for any other solid organ recipients. That is in accordance with the registry analyses and the clinical trials listed below demonstrating the highest graft survival rates for recipients given antibody induction therapy and maintained on Tacrolimus.
A large European multicenter study compared the efficacy and safety of Tacrolimus versus the microemulsion formulation of Cyclosporine in 205 SPK recipients. All of the patients received additionally rabbit anti-T-cell induction therapy, MMF and short-term corticosteroids. The study showed a significantly higher pancreas graft survival rate with Tacrolimus (91%) than with Cyclosporine (74%; P<0.0005).3 A second US multicenter study focused on the effect of antibody induction therapy in SPK recipients. The trial conducted at 18 US pancreas transplant centers, randomized 87 recipients each to antibody induction therapy versus no therapy. In the induction group, either T-cell depleting or nondepleting antibodies were used. Maintenance therapy in both groups was Tacrolimus, MMF and steroids. At 3 years, actual patient survival rates (94% vs. 90%) and pancreas graft survival rates (76% vs. 76%) were similar between the two groups, but actual kidney survival rates were significantly higher in the induction group (92% vs. 82%; P=0.04).4 A third US-Canadian multicenter study assessed the safety and efficacy of two dosing regimens of daclizumab versus no antibody induction in 185 SPK recipients maintained on Tacrolimus, MMF and steroids. The probability of either kidney or pancreas rejection was lowest with two doses of daclizumab (P=0.042). The authors concluded that daclizumab is effective in reducing the incidence of acute rejection in SPK recipients, as compared with no antibody induction.5
During the past years increasingly more centers investigated the usage of Campath-1H induction therapy in combination with the calcineurin inhibitors, MMF in the absence or with a short course of steroids. A recent single-centre, retrospective study of SPK transplant recipients involved two treatment arms with Campath (n=50) and Thymoglobuline (n=58). The induction dose of Campath was 30mg and 6mg/kg for Thymoglobuline. Additionally all recipients received a prednisone-free maintenance immunosuppressive regimen of Tacrolimus and Sirolimus or MMF. The 3-year patient and graft survivals were excellent and similar between the treatment arms. The mean creatinine value 1-year post-transplant was however lower in the Campath subgroup (1.30 vs. 1.44 mg/dL). Furthermore advantages of Campath were shown by a trend of decreased rates of CMV infection, PTLD and it was also less expensive.6 The purpose of a further study was to evaluate Campath-1H preconditioning and Tacrolimus monotherapy in pancreas transplant recipients. Thirty-seven consecutive pancreas transplants (20 SPK, 10 PAK and 7 PTA) were followed up for 7 months, utilizing 30mg Campath-1H preconditioning. Two grams of intravenous methylprednisolone were administered, one prior to starting the Campath-1H and another at reperfusion. Patient survival was 100%. Pancreas and kidney graft survivals were 94% and 90%, respectively. Interestingly, all rejection episodes were preceded by tacrolimus trough levels <9.0 ng/ml for an extended period of time, while allograft rejection was not observed in pancreases or kidneys if the tacrolimus was >10 ng/ml. During the study period no infectious complications were seen. Although follow-up was short, these results suggest that a regimen of Campath-1H induction and tacrolimus monotherapy represents an effective immunosuppressive protocol for pancreas transplant recipients.7
As demonstrated above, an increasing number of transplant centres have proposed to withdraw or avoid steroids, nevertheless calcineurin inhibitors have remained the backbone of most immunosuppressive protocols. The use of antibody induction therapy for pancreas transplant recipients has been guided by practical experience, in the absence of randomised prospective trials.8 A multicenter trial involving 130 kidney transplant recipients has started in our center, investigating the safety and efficacy of Campath-1H in combination with Tacrolimus monotherapy compared to a standard Tacrolimus/MMF/steroid regimen, demonstrating excellent results with virtually no complications or side effects with Tacrolimus monotherapy after Campath-1H induction. Based on the existing clinical trials and the experience of Campath-1H therapy in our center we would like to investigate the long-term safety and efficacy of Campath-1H induction and Tacrolimus monotherapy compared to a standard regimen with ATG induction, Tacrolimus, MMF and short term steroids in a controlled, prospective, randomised trial.
