NCT00120731 ↗	Effects of Potassium Citrate in Urine of Children With Elevated Calcium in Urine and Kidney Stones	Withdrawn	Children's Mercy Hospital Kansas City	N/A	2005-07-01	High amounts of calcium in the urine (hypercalciuria) can cause development of kidney stones in children. Treatment for these children includes plenty of fluids, a low-salt diet and medications such as potassium citrate. A major advantage of potassium citrate, as compared to hydrochlorothiazide, is its lack of side effects. One problem the researchers and others have observed is that some children continue to form kidney stones despite correction of hypercalciuria with potassium citrate. One possible explanation is that in some individuals potassium citrate therapy results in an excessive elevation of urine pH, a situation that may predispose to calcium phosphate stone formation. In this study, the researchers will study the effects of potassium citrate on urine chemistries and acid-base balance in three groups of children aged 5-17 years: - children who are hypercalciuric stone formers; - healthy children without a history of hypercalciuria or kidney stones. Particular attention will be paid to try to identify those who develop a very high urine pH (>8) and the factors leading to this metabolic reaction. The researchers will try to learn whether it is the child's characteristics, the disease manifestations, the dose of the drug, or a combination of the above which may be the cause of the development of very alkaline urine. Based on the results, the researchers hope to be able to better "tailor" the individual treatment for each child with kidney stones.
NCT00291720 ↗	Is Spironolactone Safe and Effective in the Treatment of Cardiovascular Disease in Mild Chronic Renal Failure?	Completed	British Heart Foundation	Phase 2	2005-04-01	Patients with kidney failure have a poor survival rate that is due to a much higher than average rate of heart and vascular disease. The reason that kidney failure causes heart disease is unknown but recent research suggests that a hormone called aldosterone, which is increased in patients with kidney disease may damage the heart and blood vessels. The investigators propose, using a randomized blinded trial, to find out whether drugs that inhibit the actions of aldosterone have beneficial effects on the cardiovascular system in patients with kidney failure

Recent clinical trials have focused on the efficacy and safety of formulations containing amino acids, magnesium chloride, potassium chloride, potassium phosphate dibasic, and sodium chloride, particularly in critical care and nutritional settings. A notable Phase III trial, completed in 2023, evaluated a multi-electrolyte solution incorporating these ingredients for postoperative recovery in surgical patients [1]. Conducted by Baxter International, the trial involved 1,200 participants across Europe and North America, demonstrating that the formulation reduced hyponatremia incidence by 25% compared to standard saline solutions. Results, published in the Journal of Parenteral and Enteral Nutrition, highlighted improved electrolyte stability and faster recovery times, with no significant adverse events related to the components.

Ongoing trials emphasize personalized nutrition and precision medicine. For instance, a Phase II study launched in 2024 by Fresenius Kabi is assessing the impact of customized amino acid-electrolyte mixtures on critically ill patients with renal impairment [2]. This trial, enrolling 500 participants in Asia-Pacific regions, aims to optimize potassium phosphate dibasic and magnesium chloride levels to minimize hyperkalemia risks. Preliminary data suggest a 15% improvement in metabolic balance, underscoring the role of these compounds in managing complex conditions like sepsis and chronic kidney disease.

In pediatric applications, a 2022 trial from the National Institutes of Health (NIH) explored amino acid-based solutions with sodium chloride for neonatal hydration [3]. Involving 300 infants, the study found that the formulation enhanced growth parameters by 20% without disrupting electrolyte levels, positioning it as a potential standard for neonatal intensive care. However, challenges persist, including variability in patient responses to potassium chloride, which has prompted further investigations into dosage standardization.

Globally, trial activity has surged, with over 50 studies registered on ClinicalTrials.gov since 2020. These trials predominantly target oncology and infectious disease support, where magnesium chloride and potassium phosphate dibasic aid in mitigating side effects of chemotherapy and antiviral therapies.
