Pharmacokinetic Study of Tacrolimus and Mycophenolate Mofetil in Kidney Transplant Recipients with Hyperkalemia Receiving Patiromer
Open for Enrollment
Brief Summary of Protocol
High potassium in the blood (hyperkalemia) is a common condition found in kidney transplant patients. Risk factors include poor kidney function and exposure to various drugs and current treatment options are limited.
The Food and Drug Administration (FDA) approved patiromer, the study drug, for lowering high blood potassium levels. Kidney transplant patients with hyperkalemia may benefit from patiromer, but the interaction with transplant medications has not been studied. The purpose of this study is to test if patiromer will interfere with the transplant medications tacrolimus and mycophenolate mofetil (MMF).
Potential candidates are male or female kidney transplant recipients, 18 years or older, with high blood potassium levels and are taking tacrolimus and MMF for maintenance immunosuppression. Additional eligibility criteria will be discussed upon contacting the study team.
Participation in this study will last approximately two months and will include six visits to our center. After screening, eligible participants will be provided with the study drug, which will be taken daily for 30 days and asked to return in two weeks. The next two visits will take place one week apart and participants will need to stay at our center for repeat blood draws over a 12-hour period. Participants will then return once a week for three standards of care clinic visits.
There is no guarantee that subjects will benefit personally from this study. However, participation in this study may benefit others in the future.
