MECHELEN, Belgium, March 16, 2015 (GLOBE NEWSWIRE) -- Galapagos
NV (Euronext: GLPG) announced that Janssen Pharmaceutica NV and
Galapagos have mutually agreed to terminate the inflammation alliance
and option agreements between the companies. Galapagos views the
molecules emerging from the alliance as strong additions to its growing
proprietary pipeline. Among others, all rights to candidate drug
GLPG1690, a selective autotaxin inhibitor, return to Galapagos.
Galapagos has successfully completed a First-in-Human Phase 1 trial for
GLPG1690 and is preparing a Phase 2 clinical trial in idiopathic
pulmonary fibrosis (IPF).
"We are pleased
to regain the rights to GLPG1690 to pursue the most suitable clinical
application of autotaxin inhibition. There is a large unmet medical
need in IPF, and our pre-clinical data with GLPG1690 supports its
potential as a competitive and novel approach in this disease area,"
said Dr Piet Wigerinck, Chief Scientific Officer of Galapagos. "The
alliance with Janssen has been underway since October 2007 and has
generated three clinical molecules, two of which are now proprietary
Phase 2 assets of Galapagos: GLPG1205 and GLPG1690. This program is a
valuable component of our development portfolio, and regaining the
rights is a next step in our transformation into a mature biotech
company with a proprietary product pipeline."
Galapagos
identified autotaxin as playing a key role in inflammation, using an
inflammation assay in its unique target discovery platform.
Pharmacology and translational studies published by other parties in the
literature since then suggest autotaxin may play a key role in
metabolic disease, arthritic pain, oncology, and lung disease.
GLPG1690
is a potent and selective inhibitor of autotaxin. In a Phase 1 study
in healthy human volunteers, GLPG1690 demonstrated favorable safety and
tolerability, as well as a strong pharmacodynamic signal implying target
engagement. Galapagos is currently preparing a Phase 2 study in IPF,
to be filed for approval before the end of 2015.
About IPF
Idiopathic pulmonary fibrosis (IPF) is a chronic and ultimately fatal disease characterized by a progressive decline in lung function. Pulmonary fibrosis involves scarring of lung tissue and is the cause of shortness of breath. Fibrosis is usually associated with a poor prognosis. The term "idiopathic" is used because the cause of pulmonary fibrosis is still unknown. Estimated incidence of IPF is up to 16.3 per 100,000 persons in the US and 7.4 per 100,000 persons in Europe, with approximately 30,000-35,000 new patients diagnosed with IPF worldwide each year. The goals of treatment in IPF are essentially to reduce the symptoms, slow down disease progression, reduce acute exacerbations, and prolong survival. Approved treatments thus far have improved the overall survival of IPF patients, but unwanted side effects with these treatments are common, presenting an unmet need for effective treatments with safer side effect profiles.

Galapagos is
the first to show efficacy of an autotaxin inhibitor in pre-clinical
models for COPD and IPF, pointing to novel therapeutic areas for
autotaxin inhibition. The poster shows how GLPG1690 acts as a potent
inhibitor of mouse and human autotaxin (IC50: 100 -500 nM
range). Furthermore, GLPG1690 reduces inflammation in a mouse
steroid-resistant tobacco smoke model to a similar extent as a standard
therapy for COPD.
Galapagos also presents the
topline results with GLPG1690 in Phase 1 in healthy human volunteers:

GLPG1690
was safe and well tolerated up to a single oral dose of 1500 mg and up
to 1000 mg twice daily for 14 days, with no significant adverse effects
on ECGs, vital signs or laboratory parameters. The compound also showed
good oral bioavailability with a half-life of 5 hours and a
dose-proportional increase in exposure. GLPG1690 showed
concentration-dependent reduction of a relevant biomarker (plasma
LPA18:2 levels) with a maximum of approximately 90%. At steady state,
continuous reduction of this biomarker levels of >60% was observed
from 0 to 24 hours. The presentation will also include relevant
pre-clinical model data for COPD and IPF with GLPG1690.
Both the presentation and the posters will be made available on the Galapagos website after the conference.

The aim of the Phase 1 study was to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of oral single and multiple ascending doses of GLPG1690. The randomized, double-blind, placebo-controlled, single center study was conducted in 40 healthy volunteers in Belgium. In the first part of the study, single ascending doses were evaluated. In the second part, the new compound was administered daily for 14 days.
GLPG1690 proved to be safe and well-tolerated over a wide dose range in healthy volunteers. Engagement of the thus far undisclosed novel target was confirmed using a relevant biomarker. GLPG1690 displayed a favorable pharmacokinetic and pharmacodynamic profile. The data shown in Phase 1 encourage Galapagos to explore a Phase 2 study design in pulmonary disease.
"GLPG1690 is the first molecule against this target ever to be evaluated clinically, and we are pleased with the outcome of the Phase 1 study," said Dr Piet Wigerinck, CSO of Galapagos. "Galapagos continues to deliver novel therapeutics from its unique target and drug discovery engine."
In 2007, Galapagos announced an alliance agreement with Janssen Pharmaceutica NV providing the option to worldwide, commercial licenses to certain Galapagos internal inflammatory disease programs. These programs are based on novel targets for inflammatory disorders that were identified and validated by Galapagos using its proprietary target discovery engine. Subsequent Galapagos research led to the discovery of GLPG1690, a first-in-class molecule that entered the clinic for inflammatory disorders. Galapagos is responsible for execution of Phase 1 and Phase 2A studies with GLPG1690.

1.2.4.4. Illustrative Synthesis of Intermediate Gen-3-e: N-(6-bromo-2-ethyl-8-methylimidazo[1,2-a]pyridin-3-yl)-N-methylformamide
- To a suspension of formamide Gen-2-d (720 g, 2.55 mol, 1 eq.) in 5 L of acetone were added potassium carbonate (1 kg, 7.66 mol, 3 eq.) and methyl iodide (700 g, 4.93 mol, 1.9 eq.). The reaction mixture was heated to 40° C. overnight. Additional methyl iodide (25 g, 0.18 mol, 0.07 eq.) was then introduced and stirring continued for 1 h at 40° C. The reaction mixture was filtered and washed with acetone (2×300 mL) and DCM (2×300 mL). The filtrate was concentrated in vacuo and the residue was partitioned between DCM (3 L) and water (1 L). The aqueous layer was further extracted with DCM. The combined organic layers were then washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The solid was triturated with Et2O (1 L) at r.t. for 1 h, filtered off and dried to afford Intermediate Gen-3-e.
