Galapagos initiates Phase 1 First-in-Human study with GLPG1972, receives €3.5 million milestone from Servier

Mechelen, Belgium; 20 November 2015 - Galapagos NV (Euronext & NASDAQ: GLPG) announced today that GLPG1972, a first-in-class candidate drug aiming at treating osteoarthritis, has been dosed in a Phase 1 First-in-Human study.  GLPG1972 has a novel mode of action discovered by Galapagos under its collaboration agreement with Servier, and has potential application in osteoarthritis.  Galapagos will receive a €3.5 million milestone payment from Servier for this achievement.

The aim of the Phase 1 study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of oral single and multiple ascending doses of GLPG1972.  The randomized, double-blind, placebo-controlled, single center study is being conducted in at least 40 healthy volunteers in Belgium.  In the first part of the study, single ascending doses will be evaluated.  In the second part, the new compound will be administered daily for 14 days in multiple ascending doses.  Topline results are expected in the second quarter of 2016.

"The alliance with Servier in osteoarthritis has produced a first-in-class candidate drug," said Piet Wigerinck, CSO of Galapagos.  "Galapagos continues to deliver novel therapeutics from its unique target and drug discovery engine; with GLPG1972 this is the 9^th Galapagos compound with a new mode of action to be brought into the clinic."

"This milestone is an important step in the Servier alliance with Galapagos aiming at developing medicines for patients suffering from osteoarthritis, a debilitating disease for which no disease modifying treatment is currently available," said Dr. Patricia Belissa-Mathiot, Director of Servier Rheumatology Innovative Pole.

In July 2010, Servier and Galapagos announced their alliance to develop new oral medicines for the treatment of osteoarthritis.  Galapagos is responsible for the discovery and development of new candidate drugs against novel targets, and Servier has an exclusive option to license these candidates after the completion of the Phase 1 trial and phase 2A enabling activities.  Under this agreement, Galapagos is eligible to receive up to €290 million in success-based milestones, plus royalties on commercial sales.  Galapagos also retains exclusive US commercialization rights to all commercial compounds.
