AstraZeneca announced that the US Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) regarding the New Drug Application (NDA) for ZS-9 (sodium zirconium cyclosilicate). Sodium zirconium cyclosilicate is being developed for the treatment of hyperkalaemia by ZS Pharma, a wholly-owned subsidiary of AstraZeneca. Hyperkalaemia is characterised by high potassium levels in the blood serum.
The CRL followed an inspection by the FDA of the ZS-9 manufacturing facility. The CRL does not require the generation of any new clinical data. AstraZeneca and ZS Pharma are committed to working with the FDA to resolve the remaining matters under review as soon as possible.
AstraZeneca remains dedicated to developing and commercialising sodium zirconium cyclosilicate for patients with hyperkalaemia, and is confident in the profile of this potential medicine. As announced on 24 February 2017, sodium zirconium cyclosilicate received a positive opinion by the Committee for Medicinal Products for Human Use in the European Union. Any potential implications for ongoing regulatory submissions are being assessed.
