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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
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
