MECHELEN, BELGIUM--(Marketwire - November 07, 2011) -
GLPG0634 preclinical/Phase I poster presentation tomorrow at ACR 2011
Galapagos NV (Euronext: GLPG) announced
today that it will disclose topline results from the Phase II Proof-of-
trial for GLPG0634, a selective inhibitor of JAK1 (Janus kinase1), in
arthritis patients on 22 November 2011. Financial analysts,
journalists are invited to attend a webcast press conference to be held
Galapagos operations in Leiden, Netherlands, starting at 15.00
EST/6:00 AM PST.
Preclinical and Phase I clinical results for GLPG0634 will be
tomorrow at the American College of Rheumatology Annual Meeting (ACR)
place 5-9 November 2011 at McCormick Place in Chicago:
GLPG0634 Shows Selective Inhibition of JAK1 and Maintained JAK-STAT
in Healthy Volunteers (8-Nov, 9:00 - 11:00 AM, Poster presentation #2210)
The presented data demonstrate that GLPG0634 shows selective JAK1
good safety and maintained JAK1-related biomarker response for up to
after dosing in healthy volunteers. Biomarker data also show that
inhibited throughout the day for once-daily dosing of GLPG0634 in

Details of the Phase II clinical trial
The clinical Proof-of-Concept Phase II trial for GLPG0634 involved 36
with active rheumatoid arthritis, showing an insufficient response to the
standard-of-care treatment, methotrexate (MTX). The aim is to evaluate the
efficacy and safety of GLPG0634 in treating rheumatoid arthritis. Three
of 12 patients with moderate to severe disease received either a once- or
daily dose regimen of GLPG0634 or placebo, for a period of four weeks,
continued to take a stable background therapy of MTX. The primary efficacy
endpoint will be the ACR20 response rate, the standard primary endpoint
RA clinical trials. Secondary endpoints include improvements in DAS28,
and ACR70 rates. The safety and tolerability, and the pharmacokinetics of
GLPG0634 in rheumatoid arthritis patients will also be evaluated.
About candidate drug GLPG0634
GLPG0634 is an orally-available, novel Janus kinase (JAK) inhibitor with
selectivity for JAK1 developed by Galapagos. JAKs are critical components
signaling mechanisms utilized by a number of cytokines and growth factors,
including those that are elevated in rheumatoid arthritis patients. JAK
inhibitors have shown long-term efficacy in rheumatoid arthritis trials
early onset of action. Galapagos aims to differentiate GLPG0634 from other
inhibitors in development by specifically targeting JAK1, a strategy which
result in a cleaner safety profile.
GLPG0634 has demonstrated excellent activity in in vitro biochemical
in vivo models of rheumatoid arthritis, and has successfully completed
clinical development and Phase I studies in healthy volunteers.
