Study Arms:
- KHK7791 (Type: EXPERIMENTAL): During the dosing period, subjects administer KHK7791 twice daily just before meals.Subjects will be underwent tests at scheduled visits at least weekly until Week 12, at least once every 2 weeks after completion of Week 12 test.~KHK7791 and phosphate binders are adjusted with the goal of controlling serum phosphorus concentration within a certain range based on the dose adjustment criteria described in the study protocol.It should be considered that phosphorus adsorbent should be switched to KHK7791 whenever feasible.

Based on this trial design, predict the completion outcome and termination type (if applicable).
