Keywords: Soluble ferric pyrophosphate Chronic kidney disease Chronic hemodialysis Ferric pyrophosphate citrate
Allocation: RANDOMIZED | Intervention model: CROSSOVER
Enrollment: 718
Healthy volunteers: no

Brief summary:
The purpose of the parent study is to assess the short-term safety and tolerability of soluble ferric pyrophosphate (SFP) in dialysate administered to a large number of representative adult chronic kidney disease patients on hemodialysis (CKD-HD).

The purpose of the extension study is to assess the long-term safety and tolerability of SFP.

Detailed description:
Parent Study: randomized, double-blinded, crossover, up to 6 weeks, 700 patients. Patients were randomized to receive SFP 2 µmoles (110 µg) iron/L of dialysate in liquid bicarbonate concentrate or placebo (standard liquid bicarbonate concentrate) x 2 weeks, then a 1 week washout, then crossed over to the alternate treatment x 2 weeks.

Extension Study: open-label, single active arm, uncontrolled study, up to 53 weeks, 300 patients. Following completion of the RMTI-SFP-6 parent study, patients could enter the extension study, where they received SFP 2 µmoles (110 µg) iron/L of dialysate in liquid bicarbonate concentrate for up to 52 weeks.

Arms:
arm 1: Soluble ferric pyrophosphate (SFP) 2 µmoles (110 µg) iron/L of dialysate in liquid bicarbonate concentrate x 2 weeks, then 1 week washout, then standard liquid bicarbonate concentrate without SFP x 2 weeks arm 2: Standard liquid bicarbonate concentrate without SFP x 2 weeks, then 1 week washout, then soluble ferric pyrophosphate (SFP) 2 µmoles (110 µg) iron/L of dialysate in liquid bicarbonate concentrate x 2 weeks.

Interventions: intervention 1: SFP intervention 2: Placebo
Intervention descriptions: intervention 1: Dialysis with SFP administered via the liquid bicarbonate concentrate at a concentration of 2 µmoles (110 µg) iron/L of dialysate intervention 2: Dialysis with standard liquid bicarbonate concentrate without iron
