Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive six months’ treatment with the Theranova dialyzer three times per week. Theranova, the Baxter Mid Cut-Off dialyzer has a pore size of 7 nm but narrower distribution of pores compared to high cut-off membrane. It has been designed to provide increased clearance of these larger middle-molecules in chronic haemodialysis patients, compared with high flux HD (the standard HD treatment method).

Prior to intervention, participants will also receive a one-month wash-in and one month wash out period after treatment period using the Revaclear high-flux membrane.

Although all dialysis prescriptions will remain under the supervision of the local nephrology team (thus prescriptions may vary based on local and individual patient requirements), the following treatment guidance is provided:
- target blood flow >300mls/min,
- dialysate flow rate 500mls/min,
- fluid removal to participant’s individual prescription

All participants are in-centre patients and will be withdrawn from treatment if participant transfers to another renal unit which is not an active study site
