Adverse reactions compared to placebo and iron dextran Beckie Michael, Daniel W. Coyne, Steven Fishbane, et al. Kidney International. 2002;61:1830-1839.[6]

Study Description
Objectives: (1) To compare the adverse event profile of FERRLECIT with that of placebo and iron dextran (through historical controls) and (2) to evaluate the safety of FERRLECIT when given as an IV push (12.5 mg/min) Study Design: Novel, phase IV, multicenter, crossover, randomized, double-blind, placebo-controlled, single-dose safety study.

Study Population: 2534 FERRLECIT-naïve hemodialysis (HD) patients with or without previous iron dextran exposure. Patients concurrently using antihistamines or corticosteroids were excluded.

Study Protocol: Patients were randomized into one of two crossover treatment
schedules: FERRLECIT, or sodium ferric gluconate complex (SFGC), was administered at the rate of 125 mg IV push over 10 minutes at HD session 2 and placebo (10 mL bacteriostatic saline) at session 3 OR placebo at HD session 2 and FERRLECIT at HD session 3. No test dose was administered

Study Results

•	Overall rate of serious adverse events was 0.6% for FERRLECIT and 0.5% for placebo (P = 0.845)
•	Rate of life-threatening adverse events with FERRLECIT was 0.04%
•	No cross-reactivity observed between FERRLECIT and iron dextran in patients previously treated with iron dextran
•	Discontinuation rate due to treatment-related adverse events was 0.04% for FERRLECIT and 0.04% for placebo (1/2534)
•	No relationship observed between incidence/severity of adverse reactions and concomitant ACE inhibitor therapy

Author's Conclusions

•	Administration of FERRLECIT is associated with a low incidence of potentially severe hypersensitivity reactions.
•	Overall rate of serious adverse events with FERRLECIT was 0.6% and 0.5% for placebo.
•	FERRLECIT does not require a test dose.
•	FERRLECIT can be administered IV push (12.5mg/min)
