Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
2X2 Crossover study - comparison of 2 different dialysis membranes plus comparison of NHD vs HDF.

Baseline status (prior to first study treatment): Nocturnal haemodialysis (8 hour sessions, 3.5x per week) - performed at home, using Fresenius Cordiax dialysers.

Randomisation 1: randomised to either remain on the Fresenius Cordiax dialysers OR to change to Nipro Elisio dialysers - of similar surface area.

Randomisation 2: enter cross-over trial of either NHD followed by HDF or vice versa; both with a 2 week washout (regular nocturnal HD) in between.
The study session will be the last dialysis session of each 2-week study period (NHD and HDF): for NHD this study session will be performed in the Home training unit.
Trial comparator: Haemodiafiltration (4 hour sessions, 3x per week) - performed in the Home Dialysis Training Unit under nurse supervision.
Study periods are 2 weeks each, with the last session in the 2-week period being the tested session. There is a 2 week washout between the two periods, wherein patients return to their baseline (NHD) treatment pattern.

For the 2-week NHD study period, patients will have 3x per week dialysis (rather than 3.5x) to allow closer comparison.

Treatment: Other
Comparator / control treatment
Nocturnal haemodialysis - 8 hour, overnight dialysis sessions at 250 ml/min blood flow and 300 ml/min dialysate flow - 3 - 3.5 times per week. Performed without supervision at home; except for the final study session which will be performed in the Dialysis Unit.

The patients will usually be using the Fresenius membrane prior to the study. The Nipro Elisio dialyser will be considered the comparator membrane.
Control group
Active
