1. February 27, 2013. N13/36. STATEMENT ON A NONPROPRIETARY NAME ADOPTED BY THE USAN COUNCIL. USAN (ZZ-19). SUCROFERRIC …
The US Food and Drug Administration has given the green light to Vifor Fresenius Medical Care Renal Pharma’s hyperphosphatemia drug Velphoro.
The approval for Velphoro (sucroferric oxyhydroxide), formerly known as PA21, is based on Phase III data demonstrated that the drug successfully controls the accumulation of phosphorus in the blood with the advantage of a much lower pill burden than the current standard of care in patients with chronic kidney disease on dialysis, namely Sanofi’s Renvela (sevelamer carbonate). read this at
Velphoro (PA21) receives US FDA approval for the treatment of hyperphosphatemia in Chronic Kidney Disease Patients on dialysis
Velphoro (sucroferric oxyhydroxide) has received US Food and Drug Administration (FDA) approval for the control of serum phosphorus levels in patients with Chronic Kidney Disease (CKD) on dialysis. Velphoro will be launched in the US by Fresenius Medical Care North America in 2014.
Velphoro (previously known as PA21) is an iron-based, calcium-free, chewable phosphate binder. US approval was based on a pivotal Phase III study, which met its primary and secondary endpoints. The study demonstrated that Velphoro® successfully controls hyperphosphatemia with fewer pills than sevelamer carbonate, the current standard of care in patients with CKD on dialysis. The average daily dose to control hyperphosphatemia was 3.3 pills per day after 52 weeks.
Velphoro was developed by Vifor Pharma. In 2011, all rights were transferred to Vifor Fresenius Medical Care Renal Pharma, a common company of Galenica and Fresenius Medical Care. In the US, Velphorowill be marketed by Fresenius Medical Care North America, a company with a strong marketing and sales organization, and expertise in dialysis care. The active ingredient of Velphoro is produced by Vifor Pharma in Switzerland.
Hyperphosphatemia, an abnormal elevation of phosphorus levels in the blood, is a common and serious condition in CKD patients on dialysis. Most dialysis patients are treated with phosphate binders. However, despite the availability of a number of different phosphate binders, up to 50% of patients depending on the region are still unable to achieve and maintain their target serum phosphorus levels. In some patients, noncompliance due to the high pill burden and poor tolerability appear to be key factors in the lack of control of serum phosphorus levels. On average, dialysis patients take approximately 19 pills per day with phosphate binders comprising approximately 50% of the total daily pill burden. The recommended starting dose of Velphoro is 3 tablets per day (1 tablet per meal).
Full results from the pivotal Phase III study involving more than 1,000 patients were presented at both the 50th ERA-EDTA (European Renal Association European Dialysis and Transplant Association) Congress in Istanbul, Turkey, in May 2013, and the American Society of Nephrology (ASN) Kidney Week in Atlanta, Georgia, in November 2013. Velphorowas shown to be a potent phosphate binder, with lower pill burden and a good safety profile.
Based on these data, Vifor Fresenius Medical Care Renal Pharma believes that Velphoro offers a new and effective therapeutic option for the control of serum phosphorus levels in patients with chronic kidney disease on dialysis.
The regulatory processes in Europe, Switzerland and Singapore are ongoing and decisions are expected in the first half 2014. Further submissions for approval are being prepared.
