Optimering av NULOJIX®-användning för att minimera CNI-exponering vid samtidig pankreas- och njurtransplantation
Optimering av NULOJIX® (Belatacept)-användning som ett sätt att minimera CNI-exponering vid samtidig pankreas- och njurtransplantation (CTOT-15)
The purpose of this study is to find out if the drug NULOJIX® (belatacept) will minimize the amount of other anti-rejection medications necessary and thereby reduce the long-term side effects caused by the other medications. The researchers also want to learn more about the safety of this treatment and long term health of transplanted pancreases and kidneys.

Detaljerad beskrivning
Transplant recipients have to take anti-rejection medications to prevent their immune systems (the body's natural defense system against illness) from rejecting their new organs. Most patients who receive a transplanted organ must take these anti-rejection medications for the rest of their lives, or for as long as the transplanted organ continues to work. Taking standard anti-rejection medications for a long time can cause serious side effects, including pancreas and kidney damage. There would be a benefit to finding new anti-rejection medications that work just as well, but could lessen the amount of anti-rejection medications that are taken long term.

The Slope of eGFR by CKD-EPI Over Time Based on Serum Creatinine Post-Transplant
Tidsram: Day 28 through Week 52 Post-Transplant
|
The estimated Glomerular Filtration Rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI):
