Amgen is investing $100m today in the construction of a new vial filing line with new technology and site infrastructure at its manufacturing plant in Dun Laoghaire in Co Dublin.

The investment is one of Amgen's largest construction projects outside North America and will lead to the creation of 150 construction jobs.

Amgen's Dun Laoghaire plant specialises in formulation, aseptic drug product filling, lyophilisation, packaging as well as analytical testing using on-site laboratories.

The Amgen plant in Dun Laoghaire is celebrating its 10th anniversary this year and currently employs 670 staff.

Construction on the new vial line has already begun and is due to be completed and fully operational by 2024.

Paul Greene, Amgen's vice president for Regional Manufacturing, said today's investment will enable it to serve more patients here in Ireland and all over the world.

"Since we acquired the manufacturing plant in Dun Laoghaire, we have now invested $900m to expand and update our production facilities and to bring in new products and capabilities," Mr Greene said.

"This investment is a testament to our commitment to our local community and our highly skilled workforce," he added.

Martin Shanahan, CEO of IDA Ireland, said the new investment illustrates Amgen's ongoing and welcome commitment to Ireland and is a further endorsement by a global leader in Ireland's biopharmaceutical ecosystem.
