The ADC facility expansion is expected to double the present large-scale manufacturing capacity in Visp without interrupting the current operations.
Lonza chemical manufacturing business unit head Stefan Stoffel said the investment is required to continue to support the growing product demands from the customers.
"Lonza Visp will continue to offer a fully integrated end-to-end development and manufacturing solution for ADCs, including the cytotoxic small molecules used in these products and all associated analytics," Stoffel added.
"In addition, Lonza can support protein development and manufacturing via our global biologics development and manufacturing sites."
The Visp facility expansion that has the potential to create new job opportunities is expected to be completed in the second quarter of 2014.
