Since the acquisition of the facility from Siegfried in 2007, Arena has been manufacturing its own pharmaceutical drug product Belviq in Zofingen, and, in addition, has provided contract manufacturing services to Siegfried and other third parties. Arena has now decided to divest its manufacturing facility in Zofingen.

Together with the real estate, fixtures, equipment and other assets needed for the operation of the manufacturing facility, all Arena employees and business contracts will be taken over by Siegfried.
