MECHELEN, BELGIUM -- (Marketwire) -- 02/05/13 -- Galapagos NV (Euronext: GLPG) announced
today that GlaxoSmithKline plan to initiate Phase 2 studies with GSK2586184
(formerly GLPG0778) in systemic lupus erythematosus (SLE) and chronic
psoriasis. GSK2586184 is the second selective JAK1 molecule discovered by
Galapagos to enter Phase 2 studies.

GSK2586184 is a selective JAK1 inhibitor which was discovered and developed
within Galapagos' osteoarthritis alliance with GSK. GSK in-licensed the
molecule in February 2012, gaining worldwide rights to further development
commercialization. Galapagos is eligible, without further financial
from Galapagos, to receive from GSK EUR34M in additional milestones plus up
double-digit royalties on global commercial sales of all therapeutic
of GSK2586184.

"Inhibition of JAK1 is considered a promising new therapeutic route to
inflammatory diseases. Galapagos is leading the field with two JAK1
molecules being tested in patients," said Onno van de Stolpe, CEO of
"With two of our JAK1 molecules in Phase 2, we hope that this will deliver
a new
class of medicines to patients with inflammatory diseases."

GSK plans to initiate a 12 week, multi-center, dose-ranging,
Phase 2 study investigating safety and efficacy of various doses of
in SLE patients. Furthermore, GSK will also initiate a 12 week
dose-ranging, placebo-controlled Phase 2 study investigating the efficacy
safety of GSK2586184 in chronic plaque psoriasis.

About Systemic lupus erythematosus

Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized
inflammation of many parts of the body. This inflammation is caused by the
immune system that mistakenly attacks healthy cells, leading to tissue
The cause remains unknown, but SLE occurs more often in women, especially
childbearing age. SLE is more common in those of non-European descent, with
prevalence ranges of 20 to 150 cases per 100.000 persons. Joint pain,
pain, fever, fatigue and malaise are the most common symptoms, and these
come and go unpredictably. Because these complaints are often observed with
other diseases, diagnosis of SLE is difficult. Currently there is no cure
SLE, but the symptoms can be controlled by medicines, the most common of
are non-steroidal anti-inflammatory drugs (NSAID) and anti-malarial
Those with more serious illness may require corticosteroids,
immunosuppressants, but these have side-effects and are not always

About Psoriasis

Psoriasis is an immune-mediated disease that affects the skin. It is caused
the immune system being mistakenly triggered, resulting in overproduction
of new
skin cells. The cause is not fully understood, but it is believed to have a
genetic component and certain medications and infections are well-known
factors. Psoriasis affects approximately 3% of people globally and it can
at any age, although it most commonly appears for the first time between
ages of 15 and 25 years. There are five types of psoriasis with the most
form being plaque psoriasis, characterized by red patches covered by a
white scale appearing on the top first layer of the skin. Psoriasis can
cause inflammation of the joints, which is known as psoriatic arthritis,
affecting between 10-30% of all people with psoriasis. Psoriasis is
typically a
lifelong condition and there is currently no cure, but various treatments
help to control the symptoms. Treating moderate to severe psoriasis usually
involves a combination of treatment strategies: topical treatments, light
therapy and/or systemic medications, including biologic drugs.

About Galapagos
Galapagos (Euronext: GLPG; OTC: GLPYY) is specialized in novel
with a large pipeline of four clinical, six pre-clinical, and 30 discovery
small-molecule and antibody programs in cystic fibrosis, inflammation,
antibiotics, metabolic disease, and other indications.
GLPG0634 is an orally-available, selective inhibitor of JAK1 for the
of rheumatoid arthritis and potentially other inflammatory diseases, about
enter Phase 2b studies. AbbVie and Galapagos signed a worldwide license
agreement whereby AbbVie will be responsible for further development and
commercialization after Phase 2b. Galapagos has another selective JAK1
inhibitor in Phase 2 in lupus and psoriasis, GSK2586184 (formerly GLPG0778,
in-licensed by GlaxoSmithKline in 2012). GLPG0187 is a novel integrin
antagonist currently in a Phase 1b patient study in metastasis. GLPG0974 is
first inhibitor of GPR43 to be evaluated clinically for the treatment of
this program will start a Proof of Concept Phase 2 study in Q2 2013.
The Galapagos Group, including fee-for-service companies BioFocus, Argenta
Fidelta, has over 800 employees and operates facilities in five countries,
