About Galapagos

Galapagos (Euronext: GLPG; OTC: GLPYY) is specialized in novel modes-of-action, with a large pipeline comprising five Phase 2 studies (two led by GSK), one Phase 1 study, six pre-clinical, and 20 discovery small-molecule and antibody programs in cystic fibrosis, inflammation, antibiotics, metabolic disease, and other indications.  In the field of inflammation, AbbVie and Galapagos signed a worldwide license agreement whereby AbbVie will be responsible for further development and commercialization of GLPG0634 after Phase 2B.  GLPG0634 is an orally-available, selective inhibitor of JAK1 for the treatment of rheumatoid arthritis and potentially other inflammatory diseases, currently in Phase 2B studies in RA and in Phase 2 in Crohn's disease.  Galapagos has another selective JAK1 inhibitor in Phase 2 in ulcerative colitis and psoriasis, GSK2586184 (formerly GLPG0778, in-licensed by GlaxoSmithKline in 2012).  GLPG0974 is the first inhibitor of FFA2 to be evaluated clinically for the treatment of IBD; this program is currently in a Proof-of-Concept Phase 2 study.  GLPG1205 is a first-in-class molecule that targets inflammatory disorders and has completed Phase 1.  AbbVie and Galapagos signed an agreement in CF whereby they work collaboratively to develop and commercialize oral drugs that address two mutations in the CFTR gene, the G551D and F508del mutation.  Potentiator GLPG1837 is at the pre-clinical candidate stage.  Galapagos has 400 employees, operating from its Mechelen, Belgium headquarters and facilities in The Netherlands, France, and Croatia.  Further information at: www.glpg.com
