About

Randomized, controlled, parallel groups, open-label, blinded end-point assessment, multicenter study, comparing the effects of a low glucose peritoneal dialysis solution, XyloCore, to glucose solutions (Physioneal, Fixioneal, Dianeal, Balance, Bicavera, Bicanova or Equibalance) only regimen, in patients with End-Stage Renal Disease (ESRD) receiving Continuous Ambulatory Peritoneal Dialysis (CAPD), over a 6-month study period.

Full description

Patients should be enrolled if they are receiving 1, 2 or 3 diurnal exchanges of one of the following PD solutions (standard treatment): Physioneal 35 or 40 (including Clear-Flex bag), Fixioneal 35 or 40, Dianeal or Dianeal Low Calcium (1.36%, 2.27% or 3.86% glucose), or Balance, Bicavera, Bicanova or Equibalance (1.5%, 2.3%, 4.25% glucose) - and - one bag of Extraneal (7.5% Icodextrin) for the long-dwell exchange. Patients will be centrally randomized to the investigational product (XyloCore) or the glucose-only PD solution active comparator. Patients randomized to the control group will continue with their prescription of standard treatment with 1, 2 to 3 daily (short-dwell) exchanges of Physioneal, Fixioneal, Dianeal, Balance, Bicavera, Bicanova or Equibalance PD solution. Patients randomized to XyloCore will receive XyloCore Low, Medium or High Strength according to the osmotic strength (glucose concentration) of their prerandomization prescribed PD solution. All patients will keep being prescribed Extraneal (7.5% Icodextrin) for the nocturnal (long-dwell) exchange. The osmotic strength and number of diurnal short dwell exchanges may be modified by the investigator as clinically required. PD prescriptions in both treatment arms should be tailored to reach the minimum target of a total Kt/V of > 1.7 per week throughout the study. A stratified randomization scheme will be employed to ensure balanced allocation across the two treatment groups of patients with diabetes and of patients treated with only 1 diurnal exchange. Randomization will be performed centrally via a web-based system according to a computer-generated randomization list. The study is open-label with blinded evaluator (primary endpoint), without blinding of patients or clinical staff.

XyloCore peritoneal dialysis solution

Experimental group

Description:

Patients will receive 1, 2 or 3 daily (short-dwell) exchanges with XyloCore of an osmotic strength comparable to their pre-randomization prescription of glucose peritoneal dialysis solution (XyloCore Low, Medium and High Strenght have an osmotic strength comparable to Physioneal, Fixioneal or Dianeal 1.36%, 2.27%, 3.86% glucose, respectively, and Balance, Bicavera, Bicanova or Equibalance with 1.5%, 2.5%, 4.25% glucose, respectively). All patients will receive Extraneal (7.5% Icodextrin) for nocturnal (long-dwell) exchange.

Treatment:

Drug: XyloCore Low Strenght, XyloCore Medium Strenght, XyloCore High Strenght

Glucose peritoneal dialysis solution

Active Comparator group

Description:

Patients randomized to glucose solution will continue the 1, 2 or 3 daily (short-dwell) exchanges of Physioneal 40 or 35, Fixioneal 40 or 35 or Dianeal (1.36%, 2.27%, 3.86% glucose), Balance, Bicavera, Bicanova or Equibalance (1.5%, 2.5%, 4.25% glucose) with the same osmotic strength of their pre-randomization prescription. All patients will receive Extraneal (7.5% Icodextrin) for nocturnal (long-dwell) exchange.

Drug: 1.36%, 1.5%, 2.27%, 2.5%, 3.86%, 2.25% Glucose PD Solution
