Keryx to commence phase-3 trial for Zerenex

NEW YORK Drug maker Keryx Biopharmaceuticals has finished enrolling participants for a late-stage clinical trial of a drug for patients on kidney dialysis, Keryx said Tuesday.

The company is conducting a phase-3 trial of Zerenex (ferric citrate) in patients with end-stage kidney disease on dialysis who have excessive phosphorous levels, a condition known as hyperphosphatemia.

Keryx said it expects to complete the study and report top-line data by the end of the year.
