KRX-0502 (ferric citrate)
KRX-0502 will be supplied as one caplet of ferric citrate containing 210 mg of ferric iron as ferric citrate. All patients initiated on study drug will start with a fixed dose of KRX-0502 (ferric citrate) of 6 caplets per day.
Patients will be titrated at Visits 4, 5, and 6 based on serum phosphorus lab results. If serum phosphorus levels go below normal, there will be a decrease in pills; if serum phosphorus levels go above normal, there wil be an increase in pills. The maximum number of KRX-0502 (ferric citrate) caplets per day will be 12, or 12 g/day of ferric citrate.
Patients will take study drug orally with meals or snacks or within one hour after their meals or snacks.
