German contract development and manufacturing organization Vetter has commenced construction of a 160,000-square-foot clinical manufacturing facility in Des Plaines, Illinois, marking a strategic expansion in the US. The $285 million investment includes aseptic production suites, material preparation, compounding areas, storage, labs, and offices, with an anticipated operational date by the end of 2029. This new site aims to enhance Vetter’s capacity to support early-phase drug development with low-volume injectable drug candidates, complementing its European operations. Local officials have highlighted job creation and economic growth resulting from the project.
