Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study follows adults with chronic kidney disease who are on dialysis and starting the phosphate binder Nephoxil for high blood phosphorus. Researchers track patients for 48 weeks to see how many reach a target phosphorus level of 3.5 to 5.5 mg/dL, using either a low or standard daily dose. The goal is to learn whether Nephoxil works safely in real-world medical settings.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Nephoxil capsules (a phosphate binder) taken by mouth in a low dose (1.5 g/day) or standard dose (4 g/day)
What this could lead to
If it works, Nephoxil could offer a reliable way for dialysis patients to keep blood phosphorus in a healthy range, reducing risks of bone and heart problems.
What could go wrong
This is an observational study, not a controlled trial, so results may be influenced by differences in routine care. Some patients may not reach target phosphorus levels, and side effects are possible.
