The collaboration with Zeria represents an important step in Vifor Pharma’s promise to make Veltassa® available to patients worldwide.

“We are very pleased about strengthening our partnership with Zeria and having made a significant step towards making Veltassa® available in Japan, the third-largest pharmaceutical market. We feel extremely fortunate that our trusted partner, Zeria, has chosen to further collaborate with us in offering this novel treatment to hyperkalaemia patients, including those on renin angiotensin aldosterone system inhibitor (RAASi) therapy. RAASi patients benefit in particular because Veltassa® enables them to keep receiving an optimal dose of, and therefore the maximum live-saving benefit from, RAASi treatment,” said Stefan Schulze, President of the Executive Committee and COO of Vifor Pharma Group.

About Veltassa®

Veltassa® is a sodium-free potassium binder approved for the treatment of hyperkalaemia. Veltassa® should not replace emergency treatment for life-threatening hyperkalaemia. Made in powder form consisting of smooth, spherical beads, Veltassa® is mixed with water and taken once a day with food. Veltassa® is not absorbed and acts within the gastrointestinal tract. It binds to potassium in exchange for calcium, primarily in the colon. The potassium is then excreted from the body through the normal excretion process.


About Hyperkalaemia
Hyperkalaemia, or abnormally elevated levels of potassium in the blood, is a serious condition that can lead to life-threatening cardiac arrhythmia and sudden death. It is frequently prevalent in patients who suffer from chronic kidney disease (CKD), hypertension, diabetes and/or heart failure. Patients with CKD or heart failure are at particular risk for developing hyperkalaemia, especially those treated with renin-angiotensin-aldosterone-system (RAAS) inhibitors, which can increase blood potassium levels in patients taking these medicines. There are often no warning signs, meaning a person can unknowingly experience spikes in potassium levels recurrently and be at risk for these cardiac events. Some medicines that are often prescribed to people with CKD and heart failure to help delay progression of their underlying disease can cause hyperkalaemia as a side effect. These include renin angiotensin aldosterone system (RAAS) inhibitors such as angiotensin receptor blockers (ARBs), aldosterone antagonists (AAs) and angiotensin-converting-enzyme (ACE) inhibitors.
