Exploratory Study to Explore the Safety and Efficacy of the HDx Therapy Using Theranova 500 Dialyzer in Comparison to Hemodiafiltration
- Conditions
- End Stage Renal Disease
- Interventions
- Device: HemodiafiltrationDevice: Theranova 500 medium cut-off dialyzer
- Registration Number
- NCT03499691
- Lead Sponsor
- Vantive Health LLC
- Brief Summary
Today it is well established that middle molecules comprise several compounds that are not effectively removed by high-flux dialyzers, and effective clearance of large middle molecules in the process of dialysis depends on the dialyzer membrane having large enough pore sizes, larger than the conventional high-flux dialyzers. Studies have found associations between levels of large middle molecule uremic toxins and immune dysfunction and inflammation, as well as adverse outcomes. This indicates that dialysis membranes having larger pores, enabling an expanded HD (HDx) with more effective removal of large middle molecules, can have a positive impact on the inflammatory state. While data is starting to appear on the long-term use of the HDx therapy, little is still known on how large middle molecules and inflammation markers are affected over time.
