The Largest Biotech

Driven by a team of specialists in commercial manufacturing, process sciences, quality assurance, quality control and supply chain, supported by the IT, human resources, finance and procurement functions, we transformed a vacant manufacturing site into a 64,000 square metre, world-class production facility.
