Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
KHK7791
Arm Description
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.
Outcomes
Primary Outcome Measures
Changes in serum phosphorous levels from baseline values at 8 weeks after the start of administration.
Secondary Outcome Measures
Changes in serum phosphorous levels from baseline values at each time point.
Achievement/failure of the target serum phosphorus level (serum phosphorus level: ≤ 6.0).
Time when the target serum phosphorus level (serum phosphorus level: ≤ 6.0) was achieved.
Achievement/failure of the target serum phosphorus level (serum phosphorus level: ≤ 5.5).
Time when the target serum phosphorus level (serum phosphorus level: ≤ 5.5) was achieved.
Concentrations of such as Ca × P product levels at each time point.
Changes of such as Ca × P product levels from baseline values at each time point.
