RELYPSA ENTERS two-year DETAILING AGREEMENT WITH SANOFI IN THE

UNITED STATES

REDWOOD CITY, Calif., August 10, 2015 – Relypsa Inc. (NASDAQ: RLYP), a biopharmaceutical company, today announced it has entered a two-year detailing agreement with Sanofi for Patiromer for Oral Suspension (Patiromer FOS). Patiromer FOS is Relypsa’s investigational medicine that is currently under review for the treatment of hyperkalemia with the U.S. Food and Drug Administration (FDA), with a Prescription Drug User Fee Act (PDUFA) action date of October 21, 2015.

Relypsa intends to commercialize Patiromer FOS, if approved, with its own dedicated U.S.-based commercial team and specialty sales force of approximately 120 sales representatives. Relypsa’s sales force will focus primarily on outreach to nephrologists, cardiologists and hospitals. Under the terms of the agreement, Sanofi’s nephrology sales force will complement Relypsa’s efforts by detailing Patiromer FOS in the United States for a two-year period. During the term of the agreement, Sanofi will be paid a service fee and is also eligible to receive incentive payments. The term may be extended by mutual agreement of both parties.

Relypsa will continue to be responsible for all regulatory, development, commercial, manufacturing and distribution activities for Patiromer FOS in the United States, including recording sales.

“Hyperkalemia is a serious and potentially fatal medical complication. We are continuing to work toward our goal of bringing hyperkalemia patients the first new medicine in more than 50 years,” said Xxxx X. Xxxxx, president and chief executive officer of Relypsa. “We believe this agreement will support a strong start for Patiromer FOS in the United States, if approved. Sanofi’s experienced nephrology sales force can be mobilized immediately upon potential approval and, combined with our own representatives, will enable more frequent and comprehensive outreach to nephrologists and cardiologists.”

About Patiromer for Oral Suspension

Patiromer FOS is an oral potassium binder in development for the treatment of hyperkalemia. This investigational medicine has been studied in both treatment and prevention studies, primarily in patients with chronic kidney disease (CKD), also heart failure, patients with both, and those with diabetes and hypertension. The clinical program includes a two-part pivotal Phase 3 program conducted under Special Protocol Assessment with FDA, a 12-month Phase 2 trial and a 48-hour Phase 1 onset-of-action trial.

About Hyperkalemia

Hyperkalemia, or abnormally elevated levels of potassium in the blood, is a condition which can lead to life-threatening cardiac arrhythmia and sudden death. It is frequently prevalent in patients who suffer from CKD, hypertension, diabetes and/or heart failure.

The company's two-part pivotal Phase 3 trial of its lead product candidate, Patiromer for Oral Suspension, has been completed and the primary and secondary endpoints were met. A New Drug Application for Patiromer for Oral Suspension for the treatment of hyperkalemia was accepted by the U.S. Food and Drug Administration and is currently under review. Relypsa has global royalty-free commercialization rights to Patiromer for Oral Suspension, which has intellectual property protection in the United States until at least 2030.
