This study checks how safe and effective Nephoxil capsules are for people with hyperphosphatemia, a condition where there is too much phosphate in the blood. This happens in patients with Chronic Kidney Disease (CKD) who are on hemodialysis, a treatment to clean the blood when kidneys aren't working well. The study lasts 48 weeks. Participants will take Nephoxil capsules either as a low dose (1.5 g/day) or a standard dose (4 g/day), decided by the doctor. The maximum dose allowed is 6 g/day. No extra visits are needed for this study, and all care will be given during regular doctor visits.
- Duration: 48 weeks, no extra visits needed.
- Doses vary from low (1.5 g/day) to a standard (4 g/day), up to 6 g/day.
- Open to adults 19+ undergoing first-time Nephoxil treatment during dialysis.
