Official title
Branched-chain Amino Acids to Improve Sarcopenia in Patients With Advanced Chronic Kidney Disease (BOOST-CKD)
Overview
Sarcopenia, or loss of muscle and strength is common in patients with poor kidney function. Although a high protein diet is generally recommended for sarcopenia, patients with poor kidney function are advised to follow a low-protein diet. In this study, we will evaluate the practicality and potential benefits of two different amino acids (molecules that form proteins) in improving sarcopenia in patients with advanced kidney disease. The study aims to improve muscle mass and strength. All study procedures are free of cost and do not require significant time commitment. You will have time to ask questions and discuss the study with your family, primary care physician, and your kidney doctor to make the decision if this is right study for you to participate in.
Detailed description
The overall objective of this study is to evaluate the feasibility, tolerability, metabolic effects, and potential therapeutic potential of isolated valine or EAA in patients with CKD stage 5.
* Primary Objective: To evaluate the feasibility, tolerability, and potential therapeutic benefits of isolated valine or EAA for the management of sarcopenia in patients with stage 5 CKD not on dialysis. * Secondary Objectives: To assess the effects of valine and EAA on measures of kidney function and anorexia in patients with stage 5 CKD not on dialysis.
