MedKoo Cat#: 206136 | Name: Filgotinib
Featured New

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Filgotinib, also known as GLPG0634, is a potent and selective JAK1 inhibitor under investigation for the treatment of rheumatoid arthritis (RA) and Crohn's disease. It is considered a promising agent as it inhibits JAK1 selectively. Filgotinib displayed a selectivity of 30-fold for JAK1- over JAK2-dependent signaling. GLPG0634 dose-dependently inhibited Th1 and Th2 differentiation and to a lesser extent the differentiation of Th17 cells in vitro.

Biological target:
Filgotinib (GLPG0634) is a selective JAK1 inhibitor with IC50 of 10 nM, 28 nM, 810 nM, and 116 nM for JAK1, JAK2, JAK3, and TYK2, respectively.
In vitro activity:
To further explore the consequences of cytokine inhibition, the effect of GLPG0634 toward Th1 and Th2 differentiation was analyzed by measuring IFN-γ or IL-13 mRNA expression levels (Fig. 2). As expected, GLPG0634 dose-dependently inhibited the differentiation of Th2 cells mediated by IL-4, a cytokine that signals through JAK1 and JAK3. GLPG0634 also inhibited Th1 differentiation with similar potencies of 1 μM or lower. Although Th1 commitment is initiated by IL-12, a cytokine signaling through TYK2 and JAK2, the primary effect of GLPG0634 on Th1 differentiation is likely through inhibition of JAK1/JAK2-mediated signaling of IFN-γ. GLPG0634 was also tested for the ability to inhibit Th17 differentiation driven by a mixture of TGF-β, IL-23, and proinflammatory cytokines (IL-6 and IL-1β), all shown to be essential for human Th17 differentiation (18). GLPG0634 inhibited Th17 differentiation under these conditions, although with lower potency than Th1 and Th2 differentiation (Fig. 2).

In vivo activity:
Mouse blood and paw samples were taken with the purpose of obtaining detailed insight in the mechanism of action of GLPG0634 in vivo. Dose selection was performed in a dose range–finding experiment (data not shown), and a dose of 50 mg/kg twice daily orally was selected for the mechanistic studies. Fig. 5A shows that the 50 mg/kg dose provided full protection against inflammation as judged by analysis of the clinical score of paws. Histological analysis of the mice paws showed that GLPG0634 protected bone and cartilage from degradation (Fig. 5B). Immunohistochemistry performed on the same samples showed that GLPG0634 effectively reduced infiltration of T cells (CD3+ cells) and macrophages (F4/80+ cells) in the paw (Fig. 5C). In paws, GLPG0634 reduced the levels of inflammatory and metalloprotease genes previously linked to disease progression, explaining the beneficial role of GLPG0634 in the mouse CIA model (Fig. 5D). The mRNA levels of RANKL were also reduced in line with the decrease in the bone lesion score, suggesting that GLPG0634 might protect against bone degradation by reducing the formation and activity of osteoclasts. GLPG0634 decreased the serum levels of all cytokines and chemokines measured, including IL-6, IP-10, XCL1, and MCP-1 (Fig. 5E). These observations indicate that GLPG0634 might affect inflammatory cytokine signaling and chemoattraction of T cells and monocyte/macrophages by reducing these cytokine and chemokine levels. At the mechanistic level, the reduction of Mx1 and Mx2 mRNA levels by GLPG0634 was also observed in mouse paws (Fig. 5F), as observed in the rat (Fig. 3). Of interest, the changes in Mx1 and Mx2 gene expression in WBCs were not altered by etanercept treatment (Fig. 5G), showing that GLPG0634 specifically impacts JAK1 signaling.
