Vifor Fresenius Medical Care Renal Pharma Ltd. announced they have entered into an exclusive partnership to commercialize Patiromer for Oral Suspension (Patiromer FOS), Relypsa's investigational medicine for the treatment of hyperkalemia.
Under the terms of the agreement, Relypsa will receive an upfront cash payment of $40 million and will be eligible to receive payments of up to $125 million upon achieving certain regulatory and sales based milestones. In addition, Relypsa will receive tiered double-digit royalties on net sales of Patiromer FOS in the licensed territories. VFMCRP will obtain an exclusive marketing right from Relypsa in worldwide territories except the United States and Japan, where Relypsa retains all commercial rights.

Patiromer FOS is an oral potassium binder being developed for the treatment of hyperkalemia, a potentially life-threatening condition defined as abnormally elevated levels of potassium in the blood. Hyperkalemia occurs most frequently in patients with chronic kidney disease (CKD) and heart failure.
