Study to Assess Safety and Effectiveness of Fixed Dose AP306 in Adults with High Blood Phosphate Levels on Maintenance Hemodialysis

What this Trial Is About

This research aims to evaluate the safety, tolerability, and effectiveness of the drug AP306 at fixed doses in adults with hyperphosphatemia who are undergoing maintenance hemodialysis. Hyperphosphatemia is a common complication in advanced chronic kidney disease and is linked to increased risks of cardiovascular problems, fractures, and death, especially in patients receiving dialysis. The study is a randomized, double-blind, placebo-controlled Phase 2b trial designed to assess these effects. Participants will receive AP306 orally at various fixed doses or placebo, administered daily for 8 weeks. The drug is given either twice or three times daily depending on the dose group, with doses ranging from 75 mg to 125 mg per administration. The study includes seven cohorts, six receiving different doses of AP306 and one receiving placebo, to compare safety and serum phosphate-lowering effects. Throughout the study, participants will be monitored with regular assessments including blood tests to measure serum phosphate levels and other safety parameters. Researchers will evaluate how well AP306 lowers phosphate levels over the 8-week treatment period. Participants adherence and tolerability to the medication will also be tracked. The trial will continue until March 2027, with data collection focused on treatment response and safety.
