Galapagos reports results with GLPG1205 in ulcerative colitis

• Phase 2a study confirms good pharmacokinetics, safety and tolerability
• In ulcerative colitis patients, primary endpoint for efficacy was not met

MECHELEN, Belgium, Jan. 26, 2016 -- Galapagos NV (Euronext & NASDAQ: GLPG) announced today that the ORIGIN Phase 2a study with GLPG1205 confirmed good pharmacokinetics, safety and tolerability.  The endpoints for efficacy of GLPG1205 in patients with ulcerative colitis (UC), however, were not met.  Galapagos will discontinue clinical development in UC.  

The ORIGIN study results showed that GLPG1205 did not statistically significantly differentiate from placebo on (partial) Mayo scores.  GLPG1205 was shown to be overall safe and well-tolerated by patients in the ORIGIN study; exposure data were in line with the healthy volunteer data from the previous Phase 1 clinical study.  Further details about the ORIGIN study will be published later during 2016.
Galapagos will evaluate whether GLPG1205 will be developed in alternative indications.
