US-based pharmaceutical company Alexion is to open offices and a laboratory facility in Dublin, which will lead to the creation of 50 jobs.

The Connecticut-based company will also establish a global supply chain facility in Ireland, which will begin supplying its drug Soliris to patients by the end of the year.

IDA Ireland, which is backing the new jobs, said Alexion's arrival in Ireland means that seven of the world’s top ten bio-pharma companies now operate in the country.

Alexion specialises in severe diseases that are also described as "ultra-rare".

Its Soliris drug is approved to treat paroxysmal nocturnal hemoglobinuria and atypical haemolytic uremic syndrome – two rare diseases that affect the blood.
