Catalent Biologics Completes Madison Facility Expansion to Double Clinical and Commercial Drug Substance Capacity

4 mins read

Catalent, the leading global provider of advanced delivery technologies, development, and manufacturing solutions for drugs, biologics, cell and gene therapies, and consumer health products, today announced that it has completed the expansion of two new suites at its biologics drug substance development and manufacturing facility in Madison, Wisconsin, and has now commenced work on customer programs. The expansion has increased the number of manufacturing suites at the site to five, more than doubling its overall CGMP-scale capacity.

Catalent first announced the investment to add two new mammalian cell culture suites at the Madison site in January 2019. Each new suite includes a 2×2,000-liter single-use bioreactor system capable of processing batches of 2,000 liters or 4,000 liters for CGMP clinical and commercial manufacturing. The first engineering batch in the new suite began in March 2021, with the first CGMP batch expected to be manufactured during May. The second new suite is being prepared to begin its first engineering batch in May, ahead of its first CGMP batch in mid-July.

This new capacity will allow us to meet growing clinical and commercial demand from both existing and new customers. Catalent’s continued investment in technology and capacity will enable us to bring our customers’ important and innovative treatments to patients faster–Mike Riley, Region President, Biologics, North America
