Efficacy of pHA130 Hemoadsorption on Protein-Bound Uremic Toxins and Quality of Life in Kidney Failure (PHOENIX)
A Prospective, Multicenter, Randomized Controlled Trial of HAHD With pHA130 Cartridge vs. Conventional High-Flux HD for Clearance of Protein-Bound Uremic Toxins and Quality of Life Improvement in Kidney Failure.
Patients on maintenance hemodialysis (MHD) face a high risk of cardiovascular mortality and reduced quality of life. Conventional high-flux hemodialysis (HD) is the standard of care but has limited efficacy in clearing middle-molecular and protein-bound uremic toxins (PBUTs). The accumulation of these toxins is associated with adverse long-term outcomes.
This study evaluates the efficacy and safety of the pHA130 hemoadsorption cartridge, which utilizes a modified resin for enhanced PBUT adsorption, when combined with hemodialysis (HAHD). This is a prospective, open-label, multi-center, randomized controlled trial involving 100 MHD patients. Participants will be randomized 1:1 to either the HAHD group (receiving one HAHD session using the pHA130 cartridge and two standard HD sessions weekly) or the Control group (receiving three standard HD sessions weekly).
The primary objective is to assess the reduction in serum indoxyl sulfate (IS) and p-cresol sulfate (PCS) levels from baseline to 12 months. Secondary objectives include evaluating changes in quality of life (KDQoL-SF, MMSE), the progression of coronary artery calcification (CAC), the incidence of major adverse cardiovascular events (MACEs), all-cause mortality, and safety profiles. This trial aims to determine if integrating long-term HAHD therapy can optimize blood purification strategies for the MHD population.

Patients with chronic kidney disease (CKD), particularly those on maintenance hemodialysis (MHD), face a high burden of cardiovascular disease and significantly impaired health-related quality of life. Traditional hemodialysis (HD) and hemodiafiltration (HDF) are effective at clearing small water-soluble molecules, but their efficacy in removing protein-bound uremic toxins (PBUTs)-such as indoxyl sulfate (IS) and p-cresyl sulfate (PCS)-is notably limited. The accumulation of PBUTs is strongly associated with vascular calcification, increased cardiovascular mortality, and severe symptoms like uremic pruritus.
Hemoadsorption combined with hemodialysis (HAHD) has emerged as a promising strategy to address this gap. The novel pHA130 hemoadsorption cartridge features a modified resin with micro-controlled positive charges, enhancing its targeted adsorption capacity for PBUTs through electrostatic, hydrophobic, and molecular sieving mechanisms. In vitro studies have shown IS and PCS clearance rates exceeding 90%.
The PHOENIX trial is a prospective, open-label, multicenter, randomized controlled trial designed to evaluate the long-term clinical efficacy and safety of the pHA130 cartridge in MHD patients. Following a 4-week run-in period, eligible participants will be randomized 1:1 into two arms:
Experimental Group (HAHD): Receives high-flux HD twice a week and HAHD once a week. During HAHD, the pHA130 cartridge is placed in series before the high-flux dialyzer.
Control Group (HD): Receives conventional high-flux HD three times a week.
The primary endpoint is the percentage reduction in serum IS and PCS concentrations from baseline to 12 months. Secondary endpoints include changes in health-related quality of life (assessed by KDQoL-SF) and cognitive function (assessed by MMSE), progression of coronary artery calcification (CAC) measured by Agatston score, incidence of major adverse cardiovascular events (MACEs), all-cause mortality, and safety metrics. The results of this study aim to provide robust evidence for optimizing blood purification strategies and improving long-term outcomes for patients with end-stage renal disease.
