Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate the efficacy of KHK7791 in combination with phosphate binders by comparing changes in serum phosphorus levels between hemodialysis patients with hyperphosphatemia receiving repeated administration of KHK7791 30 mg in combination with phosphate binders for 6 weeks and those receiving placebo in combination with phosphate binders.

KHK7791

During the dosing period, subjects administer the study drug (KHK7791 or placebo) twice daily just before meals in a double blind. The starting dose of the study drug is 5 mg at a time, and the dose is adjusted in the range of 5, 10, 20, and 30 mg at a time based on the dose adjustment criteria described in the study protocol. Dosage adjustment is performed step by step.
