REDWOOD CITY, Calif., March 16, 2015 (GLOBE NEWSWIRE) -- Relypsa Inc. (Nasdaq:RLYP), a biopharmaceutical company, today highlighted multiple data presentations of Patiromer for Oral Suspension (FOS) at the 2015 World Congress of Nephrology. Patiromer FOS, Relypsa’s lead product candidate, is an oral potassium binder being developed for the treatment of hyperkalemia.
The data presented at the meeting demonstrated consistent safety and efficacy of Patiromer FOS across multiple studies and were included in Relypsa’s New Drug Application (NDA) for Patiromer FOS that was accepted by the U.S. Food and Drug Administration (FDA) in December 2014. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) date of October 21, 2015 for completion of the review of the NDA for Patiromer FOS.
“Relypsa’s NDA for Patiromer FOS is supported by a package of robust clinical data from eight clinical studies,” said Lance Berman, M.D., chief medical officer of Relypsa. “Patiromer FOS has performed consistently in terms of both safety and efficacy across all studies, including across multiple disease and patient sub-groups.”

- Mechanism of Action of Patiromer For Oral Suspension: Increases Fecal K[plus] Excretion in Health Subjects Independent of Race (Epstein, et al; Poster #218)
- Attainment of Normokalemia in Patients With Chronic Kidney Disease and Moderate to Severe Hyperkalemia on RAAS Inhibitors: Clinical Trial Results With Patiromer (Epstein, et al; Poster #219)
- Patiromer For Oral Suspension Produces Prompt and Sustained Reductions in Serum K[plus] in CKD Patients with Moderate-to-Severe Hyperkalemia on RAAS Inhibitors (Epstein, et al; Poster #220)
About Hyperkalemia
Hyperkalemia, a serious condition defined as abnormally elevated levels of potassium in the blood, is frequently prevalent in patients who suffer from chronic kidney disease, hypertension, diabetes and/or heart failure. Hyperkalemia can lead to life-threatening cardiac arrhythmia and sudden death. Patients with chronic kidney disease or heart failure are at particular risk for developing hyperkalemia, especially those treated with renin-angiotensin-aldosterone-system (RAAS) inhibitors such as ARBs (Angiotensin Receptor Blockers), AAs (Aldosterone Antagonists), and ACE (Angiotensin-Converting-Enzyme) inhibitors. Although RAAS inhibition has been shown to protect kidney and cardiac function, many patients who could benefit from RAAS inhibitors are untreated or undertreated due to the undesirable side effect of increasing serum potassium.
About Patiromer FOS
Patiromer FOS is an oral potassium binder being developed for the treatment of hyperkalemia. The compound has been evaluated in CKD patients with hyperkalemia, including a two part Phase 3 program, a 12-month Phase 2 trial and a 48-hour Phase 1 onset-of-action trial. In all of those trials, Patiromer FOS met its efficacy endpoints and the treatment was well tolerated. The pivotal clinical trial for Patiromer FOS was conducted under a Special Protocol Assessment with the FDA.
