AstraZeneca Pharmaceuticals LP issued the following announcement on May 18.
The US Food and Drug Administration (FDA) has approved Lokelma (sodium zirconium cyclosilicate), formerly ZS-9, for the treatment of adults with hyperkalaemia, a serious condition characterised by elevated potassium levels in the blood associated with cardiovascular, renal and metabolic diseases.
The risk of hyperkalaemia increases significantly for patients with chronic kidney disease (CKD) and for those who take common medications for heart failure (HF), such as renin-angiotensin-aldosterone system (RAAS) inhibitors, which can increase potassium in the blood. To help prevent the recurrence of hyperkalaemia, RAAS-inhibitor therapy is often modified or discontinued, which can compromise cardio-renal outcomes and increase the risk of death.
Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “We are pleased by today’s FDA approval of Lokelma as it enables us to help address a long-standing clinical need with a new medicine that offers rapid and sustained treatment for adults with hyperkalaemia. The consequences of hyperkalaemia can be very serious and it’s reassuring for treating physicians that Lokelma has demonstrated lowering of potassium levels in patients with chronic kidney disease, heart failure, diabetes and those taking RAAS inhibitors.”
Lokelma is a highly-selective, oral potassium-removing agent.1 The FDA approval is supported by data from three double-blind, placebo-controlled trials and two open-label trials, which showed that for patients receiving Lokelma the onset of action was at 1.0 hour and the median time to achieving normal potassium levels in the blood was 2.2 hours, with 92% of patients achieving normal potassium levels within 48 hou.rs from baseline. The treatment effect was maintained for up to 12 month
Steven Fishbane, MD, Professor, Donald and Barbara Zucker School of Medicine at Hofstra Northwell, New York, said: “This FDA approval represents an exciting milestone, as it stands to deliver a rapid, effective and generally well-tolerated treatment option to patients suffering from hyperkalaemia in the US.”
The European Commission granted marketing authorisation for Lokelma in the European Union on 22 March 2018.
