Novartis is shutting down Colorado plant, laying off 400 employees after overestimating gene therapy demand

Just 14 months after opening an ambitious gene therapy manufacturing facility in Longmont, Colorado, Novartis is closing up shop there.

Novartis will close the plant, 35 miles north of Denver, by July 9 and lay off about 400 employees. The six-building, 692,000 square foot complex employed scientists, engineers, analysts and manufacturing and operations personnel.
