Clinical trials overview
The available trials of Alpha-Ketophenylalanine Calcium are studying kidney-related conditions and nutrition problems.[1][2][3] These studies are asking whether the treatment may help protect muscle, reduce protein-energy wasting, and support patients during dialysis care.[1][2][3] All three listed studies are marked as authorised and are interventional trials, which means the researchers give the study treatment and then track the results.[1][2][3]
Who the trials include
One trial includes people with stage 4 or 5 chronic kidney disease who eat a moderately low protein diet of 0.6 to 0.8 g/kg/day.[1] Another trial includes patients with moderate to very severe nephrotic syndrome and focuses on prevention of muscle loss and protein-energy wasting.[2] The third trial includes incident haemodialysis patients, meaning people who have recently started dialysis, and it studies the incremental haemodialysis period.[3]
These trials are not testing the same group of patients, but they share a common goal: to see whether Alpha-Ketophenylalanine Calcium can help people with kidney disease keep more muscle or maintain a better nutrition status.[1][2][3]
What the trials measure
The first study measures muscle mass index at 12 months using DEXA, a scan that can measure body composition.[1] It focuses on appendicular lean mass, which means lean muscle in the arms and legs.[1] The goal is to see whether treatment helps protect muscle in advanced kidney disease.[1]
The second study measures change in lean body mass within 6 weeks after enrollment.[2] It is designed as a non-inferiority study, which checks whether the treatment is not worse than the comparison by more than a set amount.[2] The study also evaluates efficacy, safety, and tolerability, meaning whether the treatment works, whether it is safe, and how well patients can take it.[2]
The third study measures the duration of the incremental haemodialysis period in months.[3] In this study, incremental haemodialysis means fewer than 3 dialysis sessions per week, except in palliative or end-of-life care.[3] Researchers want to know whether adding Alpha-Ketophenylalanine Calcium to the usual nutrition plan can help prolong this period.[3]
Trial phases and design
Two of the studies are in Phase 3, which usually means a larger study that looks more closely at how well the treatment works and collects more safety information.[1][2] The third study is in Phase 2, which is often used to explore whether a treatment shows benefit in a smaller group of patients.[3]
All three trials are interventional and use oral treatment forms of Ketosteril listed in the source data.[1][2][3] The source data also shows planned enrollment of 100 patients in the CKD study, 150 patients in the nephrotic syndrome study, and 70 patients in the haemodialysis study.[1][2][3]
Key trials
2024-516764-29-00 is a Phase 3 study in stage 4 and 5 chronic kidney disease with a moderately low protein diet.[1] It measures appendicular lean mass by DEXA after 12 months and aims to see whether supplementation can help with sarcopenia, which means loss of muscle mass and strength.[1]
NCT05716880 is a Phase 3 multicentre randomized-controlled trial in nephrotic syndrome.[2] It studies prevention of protein-energy wasting and muscle loss, and it measures lean body mass over 6 weeks.[2]
2025-524093-41-00 is a Phase 2 exploratory randomized controlled trial in incident haemodialysis patients.[3] It looks at whether adding Ketosteril to the usual nutrition plan can extend the incremental haemodialysis period.[3]
Patient glossary
Authorised means the study has been approved to run, according to the source data.[1][2][3] Enrollment means the planned number of patients the study hopes to include.[1][2][3] Randomized-controlled trial means patients are assigned by chance to study groups, which helps make the results more reliable.[2][3]
Primary outcome is the main result the trial is designed to measure.[1][2][3] In these studies, the main results are muscle mass, lean body mass, and the length of the incremental haemodialysis period.[1][2][3] Tolerability means how well patients can take the study treatment in daily life.[2]
