简要总结
The purpose of this study is to demonstrate the safety of dialysate regeneration of the PAK HD sorbent cartridge and therapy efficacy of the PAK HD sorbent therapy compared with conventional hemodialysis.
详细描述
This clinical trial is being conducted to evaluate the biochemical safety of dialysate regeneration with the PAK HD sorbent cartridge in a limited number of patients and treatments. Therapy efficacy of the PAK HD sorbent therapy will be compared to conventional hemodialysis under the same therapy settings. The trial will use only one single PAK HD sorbent therapy per patient, and a total of 3 patients. The PAK HD therapies will be performed in the middle of the week.

结局指标
主要结局
The primary objective of this early feasibility clinical trial is to assess the (short term) clinical safety of the PAK HD sorbent treatment in a limited number of patients and treatments.
时间窗: 2 weeks
The clinical safety of the PAK HD will be evaluated in terms of the following primary endpoints: 1. Absence of serious adverse events (SAE) 2. Absence of critical change in patient's clinical condition and vital parameters (Blood pressure, heart rate, body temperature and respiratory rate and pulse oximetry) during treatment. 3. Absence of critical change in haematology and biochemistry immediately before the start of therapy and immediately after completion of therapy, including acid-base state, electrolytes, and ammonia.
次要结局
- The secondary objective of this study is to evaluate the efficacy of the PAK HD therapy in comparison to CHD, in terms of uremic toxin removal efficacy (urea, creatinine and phosphate).(2 weeks)
