About

Science As Limitless
As Our Curiosity

As a biopharmaceutical company led by physician-scientists, we are passionate about repeatedly pushing the bounds of
innovation to bring new medicines to patients ... over and over again.

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 Ireland operations include a state-of-the-art bulk biologics production facility in Limerick and our European Business Office in Dublin, featuring regulatory, global patient safety, clinical operations, commercial and a number of supportive administrative functions. These world-class facilities strive to redefine drug development and manufacturing and establish new standards of quality globally.
