Ardelyx Launches 'Can We Do Better?' Campaign at ASN's Kidney Week 2020

FREMONT, Calif., Oct. 22, 2020 /PRNewswire/ -- Ardelyx, Inc. (Nasdaq: ARDX), a biopharmaceutical company developing targeted, first-in-class medicines to improve the lives of patients with kidney and cardiovascular diseases, today announced the launch of its 'Can We Do Better?' Campaign at Kidney Week 2020, this year's virtual Annual Meeting of the American Society of Nephrology (ASN) that is now underway. With a new and deeper mechanistic understanding of phosphate absorption, Ardelyx is developing a new approach to advance patient care.

THE PROBLEM: Hyperphosphatemia has been shown to be an independent risk factor for high rates of cardiovascular morbidity and mortality in patients with chronic kidney disease (CKD) on dialysis. Unfortunately, most of these patients are unable to consistently achieve target phosphorus levels with the use of phosphate binders, the only currently available medications approved for the treatment of hyperphosphatemia:

• IN ANY GIVEN MONTH: ~42% of phosphate binder-treated patients on dialysis have phosphorus levels greater than the recommended target level of 5.5 mg/dL.*
• OVER A 6-MONTH PERIOD: ~77% of phosphate binder-treated patients on dialysis are unable to consistently maintain phosphorus levels <5.5 mg/dL.*

THE REASON FOR THE PROBLEM: There are limitations implicit to the mechanism of action of phosphate binders, the only class of medication approved for the treatment of hyperphosphatemia. Phosphate binders act by binding dietary phosphorus in the gut and because of how they work, must be taken with every meal, are large in size, and often require many pills per dose. These limitations make consistently achieving target phosphate levels extremely challenging for a large proportion of patients.

ADVANCING THE SCIENCE: It's time to look deeper into the science of phosphate absorption:

• NEW SCIENCE: Scientists at Ardelyx have discovered that dietary phosphate absorption occurs primarily through the paracellular pathway.
• THE OPPORTUNITY: With this new knowledge comes great opportunity - to develop novel mechanism, non-binder, targeted therapies that could provide a completely new approach to the treatment of hyperphosphatemia.

About Ardelyx, Inc.
Ardelyx is a biopharmaceutical company translating scientific breakthroughs into promise for patients, driven to advance targeted therapies where significant medical needs persist. We have developed a unique and innovative platform that has enabled the discovery of new biological mechanisms and pathways to create targeted, first-in-class, oral, small molecule therapies to meet these needs. Our lead candidate, tenapanor, is currently under FDA review for the control of serum phosphorus in adult patients with chronic kidney disease on dialysis. Our discovery platform has also led us to the discovery of a lead candidate in our RDX013 program for the potential treatment of high potassium, or hyperkalemia, a common condition in patients with kidney and/or heart disease.
