Captozyme Merges with Arranta Bio

Aaron Cowley and partners launched Captozyme in 2009. Inspired by various influences and most notably by a speech from a mother who had lost a child to a rare disease, they were driven to start the business with the passion that their efforts could result in significant change. Growing the business with a team of talented individuals dedicated to manufacturing live biotherapeutics, Captozyme merged with Arranta Bio in November 2019. The products business of Captozyme was separately spun out under the control of the former CEO.

Captozyme’s legacy facility in Gainesville, Florida continues to serve clients as Arranta Bio’s Center of Excellence for process development and early clinical supply, staffed by its experienced team under the leadership of Aaron Cowley, Chief Scientific Officer. Arranta Bio is expanding the Gainesville facility with additional PD and QC labs, and a second GMP manufacturing line.
