Study of Everolimus in de Novo Renal Transplant Recipients

2013年6月11日 更新者:Helady Pinheiro, MD, PhD

Evaluation of the Early Conversion From a Calcineurin Inhibitor-based Immunosuppressive Regimen to Everolimus in de Novo Renal Transplant Recipients, a Multicenter Experience

In the present study, the investigators propose a conversion scheme with 50% reduction in CNI dosage until adjustment of everolimus dosage, in order to reach a trough blood level of 6-10 ng/mL, thus avoiding overimmunosuppression or alternatively breakthrough rejection episodes.

The hypothesis of this study is to demonstrate that the therapeutic regimen with Myfortic® and Certican® significantly improves renal function compared with the standard regimen of CNI.

武器和干预

参与者组/臂
干预/治疗
无干预:Control

35 patients using Cyclosporin or Tacrolimus (C0=100-200/5-10ng/mL)+ Myfortic® 1440mg/dia + Steroids.

Medications will be administered orally, twice a day

有源比较器:Intervention

35 randomized Patients Converted to Certican® (Everolimus C0=6-10 ng/mL) + Myfortic® 1440mg/day + Steroids.

On the day of conversion (day 1), 2 mg everolimus will be introduced in the morning and at night, as morning dose of CsA or Tac will be maintained and evening dose of CsA or Tac will be reduced by 50%.

In two days, 2 mg everolimus will be associated with 50% of CsA or Tac original dosage, both in the morning and evening. After that, everolimus dose will be adjusted to achieve a C0 target level of 6-10 ng/mL. Once target levels of everolimus are met, the CNI drug will be suspended.
