Official title A Study to Evaluate Safety, Tolerability and Efficacy of AP306 at Fixed Doses in Dialysis Participants With Hyperphosphatemia
ClinicalTrials.gov ID: NCT06712654
What this study is testing
What is AP306 75 mg BID?
AP306 75 mg BID is an investigational medicine, taken by mouth twice daily, being studied as a potential treatment for hyperphosphatemia.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study will find out if AP306 is safe, well‑tolerated, and can lower phosphate levels in people on dialysis.
- Who it's for
- Adults who are receiving regular hemodialysis and have high blood phosphate.
- What's involved
- Participants will take set doses of AP306 and attend clinic visits for monitoring and blood tests.
- Phase 2: a mid-size study of how well it works
