Explorative Study to Investigate the Acid-base Response to Sodium and Potassium Salts in Patients With Chronic Kidney Disease.

With this research the investigators want to study how patients with chronic kidney disease respond to different sodium- and potassium salts. Potassium salts can prevent kidney damage and cardiovascular disease, however patients with chronic kidney disease can responds differently. Extra potassium can increase the amount of potassium in the blood and extra chloride can cause acidosis. With this study the investigators will gain more insight in how patients with chronic kidney disease respond to sodium and potassium salts and which one is more favorable.This information can then be used to guide the application of salt substitutes and dietary adjustments in patients with chronic kidney disease.

A Study to Investigate the Mechanistic Effects of Dapagliflozin Alone or in Combination With Balcinrenone, Compared to Balcinrenone and Placebo on Body Fluid and Electrolyte Handling and Energy Metabolism in Participants Over 50 Years of Age With Chronic Kidney Disease.

The purpose of this study is to investigate the mechanistic effects of dapagliflozin 10 mg, alone or in combination with balcinrenone 150 mg, with balcinrenone 150 mg and placebo, on the way the body handles electrolytes and water content, as well as the effects these interventions may have on energy metabolism in participants with stage 3 chronic kidney disease. The study interventions will be administered orally, daily, in addition to current therapy, for a duration of 28 days. This will allow us to maximize our ability to detect a drug effect while minimizing the drop-out rate that accompanies longer studies. In order to understand the different mechanistic effects of these interventions on energy metabolism, the study will be conducted at two study sites. The study design and treatment allocation, treatment duration as well as sample analysis for evaluation of the primary endpoint will be identical for all participants, at both sites. Therefore, urine and plasma samples for analysis of water and electrolyte handling will be collected from all study participants at both sites. In addition to the primary endpoint, the main study site (Nuremberg) will conduct a metabolic study to investigate the early- and late-effects of the interventions, while the second site, Marseille, will conduct an imaging sub-study to assess changes at the tissue level before and after treatment.
