This is a multi-centre, open label, parallel group randomized trial designed to demonstrate the therapeutic equivalence of ANDY-Disc® with Ultrabag® for a treatment period of 12 months. 270 patients on CAPD from 6 participating sites who met inclusion/exclusion criteria were enrolled into the trial. After initial screening, patients attended clinic for baseline examination, including clearance studies. Subjects were then randomly allocated to ANDY-Disc® or Ultrabag® in a ratio of 1:1. Study visits occurred every 2 weeks through 4 weeks, then every 4 weeks through 12 weeks, and every 12 weeks thereafter for the duration of the study (12 months). Hence there were a total of 7 visits (1 screen/baseline, 2 biweekly, 2-4 weekly and 2-6 monthly treatment visits, the last being the final visit).
