(RxWiki News) The makers of Zerenex have announced positive results from a three-phase study addressing the efficacy of the drug intended for dialysis patients with end-stage renal disease (ESRD).
Keryx Biopharmaceuticals has developed Zenerex as a treatment for elevated serum phosphorus levels, and so far the drug appears to be safe and well-tolerated. The drug demonstrated a statistically significant dose response in the study.
Keryx CEO called the development "perhaps the most important milestone in Keryx's history," as the company moves into a long-term study of the drug.
