All recruiting trials (5)
-
AP301, an iron-based phosphate binder, for people on dialysis with high blood phosphate
This study will test whether the iron-based drug AP301 can lower high blood phosphate in people with end-stage kidney disease who are on maintenance dialysis.
-
AP306 at fixed doses in adults on dialysis with high phosphate
This trial tests if AP306, taken daily at different doses, can safely lower phosphate levels in adults on maintenance dialysis with hyperphosphatemia.
-
Evaluating Nephoxil capsules for treating high phosphate levels in kidney disease patients on dialysis
This study is testing if Nephoxil capsules can safely help people with kidney disease on dialysis lower their high phosphate levels.
-
Understanding how drugs work in children
This study is trying to find the best and safest doses of certain medications for children and young adults under 21 who are being treated for conditions like COVID-19 and pulmonary arterial hypertension.
-
Evaluating phosphate level targets in patients with end-stage kidney disease
This study tests if lowering blood phosphate levels more strictly helps adults with end-stage kidney disease feel better and reduces their risk of heart problems.
