New hope for dialysis patients: drug targets dangerous phosphorus levels
NCT ID NCT07285291
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an experimental drug called TS-172 in 100 adults on hemodialysis who have high phosphorus levels. Participants will take TS-172 or a placebo alongside their usual phosphate binders. The goal is to see if TS-172 helps more patients reach safe phosphorus levels, which is important for heart and bone health.
