Galapagos receives €7.5 million in Servier alliances

Mechelen, Belgium; 6 March 2013 - Galapagos NV (Euronext: GLPG) today announced the achievement of milestones in the alliances with Servier in osteoarthritis and oncology.  These milestones triggered payments to Galapagos totaling €7.5 million, contributing to 2012 Group revenues.

The osteoarthritis (OA) alliance with Servier was initiated in July 2010 to deliver new oral medicines.  In October 2011 Galapagos announced a second alliance with Servier for innovative treatments in oncology.  In both alliances, Galapagos is responsible for the discovery and development of new candidate drugs against novel targets.  Galapagos is eligible to receive in excess of €500 million in success-based milestones, plus royalties on commercial sales.  The company also retains exclusive US commercialization rights to all compounds discovered.

"We are very proud to announce the delivery of high quality compounds against our novel targets in both osteoarthritis and oncology," said Onno van de Stolpe, CEO of Galapagos.  "Our alliances are proving to be very productive, with a total of eight pre-clinical candidates, 10 clinical programs, and two in-licensed programs delivered to alliance partners."

"We are very pleased with the progress of our alliances with Galapagos," said Bernard Marchand, Head of Discovery Research at Servier.  "We are confident that they will continue to deliver results."
