Pressreleases

ZS Pharma, Inc., today announced that its New Drug Application (NDA) for ZS-9 (sodium zirconium cyclosilicate) for the treatment of hyperkalemia, has been accepted for filing by the United States Food and Drug Administration (FDA).

We have been informed that the Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA is May 26, 2016.

"Hyperkalemia is a serious condition with few treatment options and ZS-9 could be the first selective agent approved for the treatment of this condition. The acceptance of the NDA is an important step toward making ZS-9 potentially available to patients with hyperkalemia," said Robert Alexander, Ph.D., Chief Executive Officer of ZS Pharma.

About ZS-9 (sodium zirconium cyclosilicate)

ZS-9 is an insoluble, non-absorbed zirconium silicate with a clearly defined three-dimensional crystalline lattice structure that was designed to preferentially trap potassium ions. The unique potassium selectivity of ZS-9 enables high in-vitro binding capacity for potassium ions even in the presence of other competing ions. ZS-9 has been studied in three double-blind, placebo controlled trials and in two ongoing 12 month open label studies in patients with hyperkalemia which represents over 1,600 patients treated with ZS-9. ZS-9 is an investigational product that is not approved for any indication in any market.

About Hyperkalemia

Hyperkalemia, or higher than normal potassium levels (typically defined as a serum potassium level > 5 mEq/L), is a life-threatening metabolic condition that can lead to cardiac arrhythmia and sudden cardiac death. Hyperkalemia is characterized by abnormally high concentrations of potassium in the blood resulting from the inability of the kidneys to excrete potassium, impairment of mechanisms that transport potassium into cells, or a combination of both factors. The causes of hyperkalemia vary but the most common are chronic kidney disease (CKD), diabetes, heart failure (HF) and side effects from cardio-renal protective drug therapy, such as renin angiotensin aldosterone system (RAAS) inhibitors.
