Plain English Summary

Background and study aims
Peritoneal dialysis is a treatment for kidney failure that uses the lining of the abdomen (peritoneum) to filter the blood inside the body. XyloCore is a new solution for peritoneal dialysis. Current commercial peritoneal dialysis solutions have a high glucose content that could alter the function of the peritoneum and increase glycemia (blood glucose level) when administered for a long time. Xylocore solutions substitute a part of this glucose with other agents (xylitol and carnitine) to preserve the function of the peritoneum and glycemia in the long term while achieving similar effectiveness compared to current commercial solutions. Preliminary results of a clinical study (phase 2) on XyloCore showed improved effectiveness and fluid removal without relevant undesirable effects. Based on the promising results from phase 2, the current study is designed to investigate if XyloCore has similar effectiveness to the commercial products containing glucose.

Who can participate?
Patients aged 18 years and over with end-stage kidney disease and treated with peritoneal dialysis in the last 3 months

What does the study involve?
There are two treatment groups - XyloCore and standard of care peritoneal solution. Patients who are eligible to participate in the study will attend an initial visit to the clinic to confirm their eligibility and a second visit when they will start treatment with XyloCore or the standard of care solution. The duration of the treatment is 6 months and during this period they will have three clinic visits - at days 30, 120 and 180. During these clinic visits they will have blood tests, physical examinations, and assessments of their vital signs and kidney function. After the treatment period patients will be switched back to the standard of care treatment.

What are the possible benefits and risks of participating?
It has been observed that patients with a peritoneal catheter may have a risk of infections, namely peritonitis (inflammation of the peritoneum). In patients performing PD the risk of peritonitis is one episode over 3 years. Anyway more than 95% of PD-related peritonitis recovered by short-term treatment with antibiotics. The risk of peritonitis is also associated with insufficient training in PD bag correct use. The study team will train the patient to use the PD bag.

Scientific titleA study to evaluate the efficacy and safety of XyloCore, a glucose-sparing experimental solution, for peritoneal dialysis
Study hypothesisThe primary objective of this study is to demonstrate the non-inferiority of XyloCore compared to the standard treatment of glucose PD solutions, with regards to the weekly Kt/Vurea.

The study will also measure:
1. Changes from the baseline values of LDL, HDL and total cholesterol, serum triglycerides, HbA1c (glycated haemoglobin), and insulin
2. Changes from the baseline values of hemoglobin and EPO requirements (medication used to manage anemia in patients on dialysis)
3. Patients’ subjective assessment of fatigue (Chalder Fatigue Scale)
4. Peritoneal ultrafiltration
5. Diuresis (24 hours urinary volume)
6. Residual kidney function (measured as the arithmetic mean of urinary urea and creatinine clearance)
Ethics approval(s)Approved 04/07/2022, East of England - Cambridgeshire and Hertfordshire Research Ethics Committee (Equinox House, City link, Nottingham, NG2 4LA, UK; Tel: not applicable; cambsandherts.rec@hra.nhs.uk), ref: 22/EE/0102
ConditionChronic kidney disease
InterventionThe purpose of the study is to evaluate if XyloCore, a new solution for peritoneal dialysis, is as safe as the commercially available solutions. There are two treatment groups: XyloCore and standard of care peritoneal solution. Patients who are eligible to participate in the study will attend an initial visit to the clinic to confirm their eligibility and a second visit when they will start treatment with XyloCore or the standard of care solution. The duration of the treatment is 6 months and during this period they will have three clinic visits at days 30, 120 and 180. During these clinic visits they will have blood tests, physical exams, and assessment of their vital signs and kidney function. After the treatment period patients will be switched back to the standard of care treatment.
Intervention typeProcedure/Surgery
Primary outcome measureTotal weekly Kt/Vurea after a 24-week period using the assigned PD solution, assessed using a peritoneal function test. In brief, in order to measure solutes (urea) and calculate peritoneal and renal Kt/V (summing up to total Kt/V), blood, spent effluent (drained volume or dialysate outflow) and urine covering 24 hours will be collected.
Secondary outcome measures1. LDL, HDL and total cholesterol, serum triglycerides, HbA1c (glycated haemoglobin), and insulin measured using lab assessment at 6 months
2. Hemoglobin and EPO requirements measured using lab assessment at 6 months
3. Patients’ subjective assessment of fatigue using the Chalder Fatigue Scale at 6 months
4. Peritoneal ultrafiltration measured using lab assessment at 6 months
5. Diuresis (24 hours urinary volume) measured using lab assessment at 6 months
6. Residual kidney function, measured as the arithmetic mean of urinary urea and creatinine clearance at 6 months
