These patent issuances build upon the Company's existing intellectual property portfolio and highlight the innovation underlying the Company's novel, highly selective, high binding capacity, potassium ion trap for the potential treatment of hyperkalemia. Similar applications have been filed with the European Patent Office (EPO) and the Patent Cooperation Treaty (PCT). ZS Pharma also intends to develop additional intellectual property describing its technologies and their utilities.
About ZS-9's Clinical Development Program
The ZS-9 clinical program is designed to investigate the treatment of acute and chronic hyperkalemia, regardless of underlying cause. ZS Pharma completed a 753-patient Phase 3 study, ZS003, which showed that ZS-9 rapidly reduced serum potassium in hyperkalemic patients to normal levels within the 48 hour Induction Phase and then controlled potassium in the normal range throughout the 12 day Extended Treatment Phase. In addition, the study provided evidence suggesting that ZS-9 is safe and well-tolerated with an adverse event profile similar to placebo.
In March of 2014, ZS Pharma initiated ZS004, its second Phase 3 clinical trial of ZS-9. ZS004 is a randomized, double-blind, placebo-controlled study designed to confirm, over a longer treatment period, the positive results previously reported for ZS003. The Company also recently initiated ZS005, an open-label, 12 month, long-term maintenance study of ZS-9. The Company plans to file a New Drug Application with the
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, congestive heart failure (CHF) and side effects from cardio-renal protective drug therapy, such as renin angiotensin aldosterone system (RAAS) inhibitors.
