About
Science As Limitless
As Our Curiosity
As a biopharmaceutical company led by physician-scientists for nearly 35 years, we are passionate
about repeatedly pushing the bounds of innovation to deliver life-altering medicines.
Whether developing new treatments or advancing manufacturing processes that act as the last stop before a medicine reaches a patient, our commitment never changes.
Our Irish operations include a state-of-the-art bulk biologics production facility in Limerick and our European locations are in Dublin and Uxbridge, UK. These world-class facilities strive to redefine the drug manufacturing process and establish new standards of quality globally.
