Background: A once-daily, modified-release oral formulation of tacrolimus has been developed to simplify dosing and improve medication adherence. There is limited data on the implementation and conversion to once-daily tacrolimus in Simultanous Pancreas-Kidney Transplant (SPK) and Pancreas After Kidney (PAK) recipients. We prospectively evaluated the safety and efficacy of a systematic switch from twice-daily tacrolimus to once-daily tacrolimus in stable pancreas transplant recipients.
Patients and Methods: From July 2013 to September 2014, 182 pancreas transplant recipients (SPK and PAK) that had been on stable immunosuppression for at least 6 months, were switched from Prograf® (twice-daily) to Advagraf® (once-daily). A 1:1.2 mg conversion was implemented to safely maintain FK trough levels. Demographics, tacrolimus trough levels, serum creatinine, estimated glomerular filtration rate (eGFR), glycohemoglobin (HbA1c) were prospectively collected before and 7 days, 3, 6 and 12 months post-conversion.
Results: Conversion from Prograf® to Advagraf® was performed in 136 SPK and 59 PAK recipients (Mean age 42.4 years, 65.1% male). Mean time from pancreas transplant to Advagraf conversion was 74.6 (+48.7) months and time of follow-up after conversion was 8 (+2.7) months. Mean Prograf® daily dose pre conversion was 5.1 (+2.9) mg and mean Advagraf® dose at conversion and at last follow up was 6.0 (+3.0) and 6.0 (+3.3) mg, respectively. FK trough levels were 8.7, 9.0, 8.0, 7.7 and 6.2 at pre-conversion, 7-days, 3-months, 6-months and 1-year post-conversion. Similarly, HbA1c were 5.4, 5.7, 5.3, 5.3, 5.3 % and eGFR were 51.0, 49.2, 50.8, 52.1, 48.5 mL/min/1.73 m2 at pre-conversion, 7-days, 3-months, 6-months and 1-year post-conversion. There were 4 (2.0%) episodes of rejection post-conversion. Average time from conversion to rejection was 5.5 (+0.9) months.
Conclusions: This is the largest report of pancreas transplant recipient outcomes after conversion to Tacrolimus once-daily. This regimen implementation is safe and effective, showing short-term stable glucose control and glomerular filtration rate, for recipients on stable immunosuppression after Simultaneous Pancreas/Kidney Transplant or Pancreas After Kidney Transplant.
