LifeSci Advisors Initiates Coverage of ZS Pharma

Phase 3 ZS-9 Data Released in Late 2013 Support NDA Filing for Hyperkalemia; Report Available for Download at

NEW YORK, NY--(Marketwired - Jan 7, 2014) - LifeSci Advisors, LLC, a leading provider of investment research and investor relations services in the life sciences sector, today announced that it has initiated coverage of ZS Pharma (private), a biotechnology company developing ZS-9, an oral, selective potassium-binding treatment for patients with hyperkalemia. ZS Pharma recently announced positive results from a Phase 3 clinical trial and completed a successful Phase 2 trial demonstrating strong safety and efficacy of ZS-9 for the treatment of hyperkalemia. Both the Phase 2 and Phase 3 trials demonstrated a statistically significant decrease in serum potassium levels after 48 hours in patients receiving ZS-9. Additional data are expected from the Phase 3 trial on the safety and efficacy of ZS-9 after 12 days of treatment. A one-month maintenance trial is expected to launch in 2014 to support an NDA for ZS-9 as a treatment for hyperkalemia.

"Despite the clear link between hyperkalemia and mortality, the treatment options are limited, and there are currently no good therapies for patients with chronic hyperkalemia," said Andrew I. McDonald, Ph.D., Founding Partner at LifeSci Advisors. "ZS-9 is a unique product that has the right combination of selectivity, patient tolerability, and efficacy to potentially become the leading treatment for hyperkalemia."

Hyperkalemia is a disease of excess potassium in the blood typically caused by conditions that impact the filtration of potassium from the kidney, such as chronic kidney disease (CKD) and heart failure (HF). It has been linked to increased mortality and is associated with cardiac arrhythmias. Blood pressure medications such as ACE inhibitors exacerbate hyperkalemia by limiting potassium excretion, so to avoid elevated potassium levels patients are often under-treated for CKD and HF. An effective hyperkalemia therapy therefore has the potential to improve the management of associated diseases. ZS-9's mechanism of action supports hyperkalemia treatment regardless of the disease etiology. ZS-9 passes through the digestive tract, selectively binding and removing excess potassium, without the safety concerns of some existing products. The Phase 3 program is designed to support a broad label for ZS-9 and could significantly expand the market by reaching patients with chronic hyperkalemia, an indication with no FDA approved therapies.

In a 40 page Initiation Report by LifeSci Advisors, we explain the scientific support for ZS Pharma's clinical program and the Company's focus on developing the leading treatment for hyperkalemia. The report discusses the potential competitive advantages of ZS-9 over existing treatments and how these advantages position the drug in the marketplace. We highlight the large market potential and treatment gaps in hyperkalemia, including the lack of therapies for chronic hyperkalemia. The report critically examines competing products and development programs, and discusses the regulatory pathway towards approval for ZS-9.
