End Stage Renal Disease
Conditions
Brief summary
This study will investigate the effect of co-administration of Triferic and heparin on the ability to maintain circuit anti-coagulation and iron delivery when compared to control conditions when each treatment is administered via separate routes.
Interventions
Triferic (ferric pyrophosphate citrate, FPC), an iron-replacement product, is an iron complex in which iron(III) is bound to pyrophosphate and citrate.
Unfractionated heparin (UFH): a common anticoagulant used during hemodialysis treatments.

Eligibility
Inclusion criteria
1. Adult hemodialysis patients ≥18 years of age. 2. Signed informed consent to participate in the study. 3. Stable on hemodialysis prescription for ≥3 months. 4. Hemoglobin concentration \>9.5 g/dL. 5. Serum TSAT ≥20%. 6. Able to receive continuous heparin infusion as their anticoagulation protocol. 7. Receiving hemodialysis via AV (arteriovenous) fistula or graft. 8. Able to receive hemodialysis for 4 hours at each session over the duration of the treatment periods.
Exclusion criteria
1. Active bleeding disorder (GI, skin, nasal…) 2. Receiving hemodialysis via catheter. 3. Receiving heparin free dialysis. 4. Receiving low molecular weight heparin as sole anti-coagulation for dialysis. 5. Receiving IV iron within 2 weeks of the first on-study hemodialysis treatment. 6. Receiving oral anti-coagulants or anti-platelet agents. 7. Any other condition, that in the opinion of the investigator would not allow completion of the 3 hemodialysis treatments in the study.
