NEW YORK (AP) — Keryx Biopharmaceuticals has received U.S. approval for a new pill to treat complications of kidney disease in patients on dialysis.
The Food and Drug Administration approved the company’s ferric citrate drug to treat patients on dialysis with hyperphosphatemia, or elevated levels of phosphates, which can increase the risk of heart disease, bone density problems and death. Keryx estimates that between 350,000 and 375,000 U.S. dialysis patients take medication to control their phosphate levels, representing a total market of $1.2 billion.
“This is a drug that has demonstrated a clear ability to benefit a very sick and burdened patient population,” CEO Ron Bentsur said Friday in an interview with the Associated Press. Benstur said the company will launch the drug in the U.S. in the next 12 weeks.
Ferric citrate is designed to be taken in two pills with each meal, for a daily regimen of six pills.
The company had initially planned to market the drug under the brand name Zerenex, though the FDA recently ruled that the name was too similar to a drug already on the market. Keryx plans to develop a new brand name ahead of the drug’s launch.
It’s the first U.S. product approval for the New York-based drugmaker, which licensed ferric citrate from a Taiwanese drugmaker in 2005. Keryx has rights to market the drug in North America, Europe and Japan, where the pill launched in May.
The company plans to soon begin late-stage testing of the drug in kidney disease patients who are not yet on dialysis.
More than 20 million people in the U.S. have chronic kidney disease and roughly 400,000 receive dialysis treatment, in which a machine filters waste from the blood in place of healthy kidneys.
