Brief Summary

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

The goal of this clinical trial is to learn if AP306 could work in the patients receiving maintenance hemodialysis with elevated blood phosphate. The main questions it aims to answer are:

* Does AP306 lower blood phosphate levels when the participants take a fixed dose of AP306?
* What medical problems do the participants have when taking AP306?

The researchers will compare AP306 to a placebo (a look-alike substance that contains no drug) to see if AP306 works to treat hyperphosphatemia.

The participants will:

* Stop all using blood phosphate-lowering drugs, and
* Take AP306 or a placebo three times a day for 12 weeks.

If the participant has a blood phosphate level above a certain level, they will receive additional treatment to lower the blood phosphate level.

3. Who has a dialysis adequacy, assessed by single pooled Kt/V (SpKt/V, estimated with blood urea) ≥1.20, at screening
4. If the participant is receiving any of the following therapies, their doses are stable for at least 4 weeks before the ICF sign off visit: phosphate-lowering products other than phosphate binders, active vitamin D and analogs or nutritional vitamin D, calcimimetics, calcitonin, and P-glycoprotein inhibitors or inducers
5. Who has a blood phosphate level within the study-required range
