AstraZeneca announced that the company successfully completed the tender offer for all of the outstanding shares of ZS Pharma and the subsequent acquisition of ZS Pharma as previously announced in November.
The transaction strengthens AstraZeneca’s cardiovascular and metabolic disease (CVMD) portfolio with the addition of the potassium-binding compound ZS-9 (sodium zirconium cyclosilicate), a potential best-in-class treatment for hyperkalaemia, a condition associated with increased mortality in patients with chronic kidney disease (CKD), diabetes mellitus (DM), and chronic heart failure (CHF). ZS-9 is under regulatory review by the US Food and Drug Administration with a Prescription Drug User Fee Act goal date of 26 May 2016. A submission for European Marketing Application Authorisation is also progressing as planned. ZS-9 complements the Company’s increasing focus on CKD and CHF, including the investigational medicine roxadustat, which is currently in Phase III development for patients with anaemia associated with CKD, as well as its leading diabetes portfolio, a comorbidity often associated with CKD and CHF patients.
The tender offer expired at 00:00 EST on 16 December 2015 and was not extended. As of the expiration of the tender offer, a total of approximately 21,948,939 shares of ZS Pharma common stock were validly tendered and not withdrawn (excluding shares tendered pursuant to notices of guaranteed delivery for which certificates have not been delivered), representing approximately 86.6% of ZS Pharma’s outstanding shares. All shares that were validly tendered and not withdrawn pursuant to the tender offer were accepted for payment.
After the acceptance of shares that were validly tendered and not withdrawn pursuant to the tender offer, AstraZeneca completed its acquisition of ZS Pharma through a merger of one of its subsidiaries with and into ZS Pharma. In connection with the merger, each outstanding share of ZS Pharma that was not accepted for payment in the tender offer (excluding shares held as treasury stock and any shares as to which appraisal rights have been validly exercised under Delaware law) were cancelled and converted into the right to receive $90.00 per share in cash, without interest and less any required withholding taxes, the same as the tender offer price. Following completion of the merger, ZS Pharma’s shares ceased to be listed on NASDAQ, and ZS Pharma became a wholly owned subsidiary of AstraZeneca.
ZS Pharma, founded in 2008, is a publicly traded biopharmaceutical company dedicated to challenging the status quo in disease states where therapeutic options have been limited.
Cardiovascular, metabolic disease and chronic kidney disease are key areas of focus for AstraZeneca as part of the company’s strategy for achieving scientific leadership and returning to growth. Our patient-led strategy is focused on addressing the multiple risk factors facing CVMD and CKD patients at different stages of their disease, with the goal of reducing morbidity and mortality through life changing medicines. One of the innovative medicines currently in Phase III development is roxadustat as a potential therapy for anaemia associated with chronic kidney disease, in patients on dialysis and those who are not on dialysis. The global development programme is being conducted by FibroGen in collaboration with AstraZeneca and Astellas.
AstraZeneca is a global, innovation-driven biopharmaceutical business that focuses on the discovery, development and commercialisation of prescription medicines, primarily for the treatment of cardiovascular, metabolic, respiratory, inflammation, autoimmune, oncology, infection and neuroscience diseases.
