Primary outcomePrimary: Change in Serum Inorganic Phosphorus at the End of Treatment From Baseline — -0.26; -0.20 mg/dL
Summary
This was a study to evaluate the efficacy and safety of HS219, chitosan-loaded chewing gum, when given three times a day for 3 weeks to the hemodialysis (HD) patients with hyperphosphatemia whose serum inorganic phosphorus was not well controlled with calcium carbonate or sevelamer hydrogen chloride.
