Shield Therapeutics plc ("Shield" or the "Group") US Composition of Matter Patent

Posted on: 06 Sep 17

LONDON, Sept. 06, 2017 (GLOBE NEWSWIRE) -- Shield Therapeutics plc (LSE:STX), a specialty pharmaceutical company focused on secondary care, is pleased to announce that the United States Patent and Trademark Office (USPTO) has allowed a composition of matter patent protecting the active substance of Feraccru®, the Group’s lead European marketed product for the treatment of iron deficiency anaemia (IDA), until late 2035 in the US.

This US patent application entitled “Crystalline Forms of Ferric Maltol”, was allowed after an expedited examination under the Global Patent Prosecution Highway program (GPPH) based on the UK patent (UK Patent No. GB2531742) "Polymorphs of Ferric Maltol", which was granted in October 2016 and protects the active substance of Feraccru through to late 2034 in the UK.  In addition, during 2017 equivalent composition of matter patents for Feraccru were granted until 2035 in Australia, Canada and Singapore.

Carl Sterritt, Founder and Chief Executive Officer of Shield Therapeutics, commented: This allowance from the US patent office - being a further result of our continuing investment in developing, strengthening and expanding Feraccru’s intellectual property - represents an important milestone for Shield. With Feraccru now protected at the composition of matter level, effectively providing market exclusivity through to 2035 in the world’s two largest and most important pharmaceutical regions (EU & US) and beyond, and with additional key clinical data on the near-term horizon, we find ourselves in a strong position from which to exploit the significant commercial potential of Feraccru.”
