Silymarin's Advantage on Graft Effectiveness (SAGE)

March 25, 2025 updated by: Matej Vnucak, University Hospital, Martin

Effect of Silymarin Supplementation on Graft Function and Early Post-transplant Complications

The study examines the impact of silymarin supplementation during the early post-transplant period, administering 900 g daily for 30 days under standard treatment. Subsequently, the investigators investigate its impact on graft function, as measured by eGFR (CKD-EPI equation), UACR or UPCR, the development of dnDSA, rejection changes, and histological changes in the 3-month biopsy protocol. At the same time, investigators will investigate the effect of silymarin on metabolic complications-PTDM, DLP, disorders of calcium-phosphate metabolism, and arterial hypertension in the post-transplant period-in comparison with the placebo group. At the same time, investigators will investigate the safety and tolerance of silymarin.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: Placebo
Patients suplemented with placebo
Placebo supplementation during the early post-transplant period (30 days) under standard treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
eGFR improvement
Time Frame: 3 months
Investigators estimate 1 month of silymarin supplementation may improve eGFR by 5 ml/min/1.73 m2 compared to palcebo at 3 months. Assuming a standard deviation of 10 ml/min/1.73 m2, a two-sided aplha of 0.005, and 80 % power, a sample size 64 participants per group is required.
3 months
Inicidence of biopsy proven acute rejection
Time Frame: 6 months
Investigators assume - by supplementing silymarine the incidence of BPAR diagnosed by 3rd month protocolar biopsy, will be lower.
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of PTDM
Time Frame: 6 months
Investigators asssume by supplementing silymarine, the incidence of PTDM diagnosed according to 2024 guidelines will be lower in observed period.
6 months
Incidence of dyslipidemia
Time Frame: 6 months
Investigators asssume by supplementing silymarine, the incidence of hypercholesterolemia or dyslipidemia will be lower in observed period.
6 months
Improved graft function in participatns with delayed graft function
Time Frame: 6 months
Investigators assume that in the group of patients with DGF, those supplemented with silymarine will have better eGFR and graft function during the observed period.
6 months
