Immunosuppression Management in Renal Transplant Recipients With Transplant Excellence Based on TruGraf Test

Intervention / Treatment
Detailed Description
The study will consist of 2 parts (Part-I and Part-II). In Part I of the study, kidney transplant recipients who are low-risk for rejection and meet the inclusion and exclusion criteria for study Part-I will be approached for informed consent in the peri-transplant period, defined as 7 days before to 5 days after transplantation. Basic clinical history and kidney transplant function that are reviewed for routine transplant care are utilized to screen patients who are approached for study discussion and informed consent.
Patients who agree to participation in the study will have received Thymoglobulin induction of at least 4.5 mg/Kg body weight total dose. These patients will have their corticosteroids withdrawn by day 30 post-transplantation and will be followed with kidney function labs at least weekly through day-90 post-transplantation. Withdrawal of corticosteroids in patients who are immunologically at low risk for acute rejection similar to this study population and have received at least 4.5 mg/kg total dose of Thymoglobulin is standard practice. Patients meeting inclusion and exclusion criteria for Part-II of the study will continue with the study. Those failing to meet the inclusion/exclusion criteria for Part-II of the study will conclude the study and will be followed per CPMC standard of care.
In Part II, study patients will be randomized to one of the two groups in a 2:1 ratio. Two patients will be randomized to the study group for every one patient to the standard of care group. A total of 75 patients will be enrolled. Fifty to the study group and 25 to the standard of care group. The patients will have post transplantation follow-up labs as standard of care and clinic visits also as standard of care. There are no additional clinic visits for the study purposes or study procedures. TruGraf blood will be collected at the same time as the standard of care blood tests and additional phlebotomy is not required.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: TruGraf - Group 1:
Patients randomized to Group 1 will receive serial TruGraf testing at months 3, 4, 5, 6, 7, 8, 9, and 12. Results will be available in real-time and used by the physician to guide management of immunosuppression.
|
TruGraf results will be available in real-time and used by the physician in conjunction with other standard of care labs to guide management of immunosuppression as follows: Patients with a stable serum creatinine and eGFR of > 45 mL/min who also have a TruGraf TX result at month 3 will have their Mycophenolate Mofetil or Mycophenolate Sodium decreased from a standard dose of 1000 mg twice daily to 500 mg twice daily or 720 mg twice daily to 360 mg twice daily respectively. Patients with a stable serum creatinine and estimated eGFR of > 45 mL/min who also have a TruGraf TX result at months 4, 5, and 6 will have their Tacrolimus target trough level decreased to a target between 3 and 6. Patients with TruGraf not-TX will have no further immunosuppression reduction and continued to be monitored.
Other Names:
|
Active Comparator: CPMC Standard of Care - Group 2:
Patients randomized to Group 2 or CPMC Standard of Care Group patients will have current standard of care laboratory assessments.
|
Patient's immunosuppression will be managed per the current CPMC standard of care that includes continuation of Mycophenolate Mofetil or Mycopheonolate Sodium at 1000 mg bid or 720 mg bid respectively.
The dose may be decreased at the discretion of the physician for drug adverse effects such as diarrhea or other gastrointestinal side-effects or neutropenia as is the standard of care.
Patients will be maintained on Tacrolimus at target levels that are considered standard of care by the managing physician.
