The aim of this study is to test if alkali treatment will preserve kidney graft function and diminish the progression of chronic kidney disease in renal transplant patients. Additionally the underlying mechanisms of nephrotoxicity of metabolic acidosis will be investigated in this cohort.
This study is a multi-center, prospective, randomized, single-blind (patient), placebo-controlled interventional trial to test the superiority of alkali treatment in comparison to placebo on preservation of kidney function in 300 kidney transplant recipients. The duration of the study will be 2 years for the individual participant. The patients will be randomized into 2 arms: intervention arm (sodium hydrogen carbonate, product: Nephrotrans®) and placebo arm (placebo comparator).
Several studies in CKD (chronic kidney disease) patients have shown that alkali therapy slows progression of CKD.

Sodium hydrogen carbonate, ATC-Code: A02AH
Placebo Comparator: Placebo
Patients will receive Placebo.
Identical capsules without active substance.
- eGFR [ Time Frame: 2 years ]Change in renal function by assessing the change in eGFR over 2 years from baseline. eGFR will be determined based on the CKD-EPI creatinine equation.
