Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a single-site, prospective, open-label, single-arm, 24-week intervention study of tirzepatide 15 mg subcutaneous injection weekly in patients with obesity and end-stage kidney disease (ESKD) on haemodialysis who are potential candidates for kidney transplant.

Tirzepatide will be administered weekly on the same day following the completion of a dialysis session by a dialysis nurse, or alternatively, self-administered by selected patients undergoing haemodialysis at home following specialised drug administration training. Adherence will further be monitored by fortnightly adverse event assessments, and regular pre- and post- dosing tirzepatide blood level monitoring.
