Amino acid supplementation for patients with end-stage kidney disease on hemodialysis

Oral Intradialytic Amino Acids Supplementation to Vitalize End-stage Kidney Disease Patients on Hemodialysis (OASIS)

Early Phase 1 Interventional The University of Texas Health Science Center at San Antonio · NCT05705414

What this trial studies

This study evaluates the effectiveness of valine, a single essential amino acid, compared to a combination of essential amino acids (EAA) in reducing fatigue, frailty, and improving cognitive function in patients with end-stage kidney disease (ESKD) who are undergoing hemodialysis. Conducted at a single center, the trial will involve patients aged 18-64 who have been receiving hemodialysis treatment at least three times a week for a minimum of six months. Participants will be monitored for changes in their physical and cognitive health as a result of the supplementation.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-64 years who have been on hemodialysis for at least six months.

Not a fit: Patients with hypersensitivity to amino acids, current substance abuse, or certain medical conditions such as heart failure or major depressive disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved quality of life and cognitive function for patients with end-stage kidney disease undergoing hemodialysis.

How similar studies have performed: While this approach is relatively novel, previous studies on amino acid supplementation in similar patient populations have shown promising results.
