Background on GLPG0634 analogue

GLPG0634 is a potent and selective inhibitor of JAK1 with IC50 values of 10, 28, 810 and 116 nM for JAK1, JAK2, JAK3 and TYK2, respectively [1].

Janus kinase 1 (JAK1) is a member of the JAK family and is a non-receptor tyrosine kinase. JAKs play an important role in the immune system. JAK1 is a potential target for the treatment of immune-inflammatory diseases [1].

GLPG0634 is a potent and selective JAK1 inhibitor. GLPG0634 inhibited JAK1, JAK2, JAK3 and TYK2 with IC50 values of 10, 28, 810 and 116 nM, respectively. In CD4+ T cells, GLPG0634 significantly reduced IL-6-induced STAT1 phosphorylation with IC50 value of 629 nM, which suggested the inhibition of JAK1. In CD33+ T cells, GLPG0634 reduced GM-CSF-induced STAT5 phosphorylation with IC50 value of 17.5 µM, suggesting the inhibition of JAK2. GLPG0634 inhibited the differentiation of Th1 and Th2 cells mediated by IL-4 and IL-12, respectively. Also, GLPG0634 inhibited Th17 differentiation induced by TGF-β, IL-23, IL-6 and IL-1β [1].

In rats, GLPG0634 significantly reduced the mRNA levels of Mx2, which were modulated by IFN-α-JAK1/TYK2 signaling. In collagen-induced arthritis (CIA) rat model, GLPG0634 significantly reduced the infiltration of inflammatory cells and reduced the levels of IL-6, IP-10, XCL1 and MCP-1 [1].

Filgotinib (GLPG0634/GS-6034), an oral selective JAK1 inhibitor, is effective as monotherapy in patients with active rheumatoid arthritis: results from a randomised, dose-finding study (DARWIN 2).[Pubmed:27993828]

Ann Rheum Dis. 2017 Jun;76(6):1009-1019.

OBJECTIVES: To evaluate the efficacy and safety of different doses of filgotinib, an oral Janus kinase 1 inhibitor, as monotherapy in patients with active rheumatoid arthritis (RA) and previous inadequate response to methotrexate (MTX). METHODS: In this 24-week phase IIb study, patients with moderately to severely active RA were randomised (1:1:1:1) to receive 50, 100 or 200 mg filgotinib once daily, or placebo, after a >/=4-week washout from MTX. The primary end point was the percentage of patients achieving an American College of Rheumatology (ACR)20 response at week 12. RESULTS: Overall, 283 patients were randomised and treated. At week 12, significantly more patients receiving filgotinib at any dose achieved ACR20 responses versus placebo (>/=65% vs 29%, p<0.001). For other key end points at week 12 (ACR50, ACR70, ACR-N, Disease Activity Score based on 28 joints and C reactive protein, Clinical Disease Activity Index, Simplified Disease Activity Index and Health Assessment Questionnaire-Disability Index) significant differences from baseline in favour of filgotinib 100 and 200 mg versus placebo were seen; responses were maintained or improved through week 24. Rapid onset of action was observed for most efficacy end points. Dose-dependent increases in haemoglobin were observed. The percentage of patients with treatment-emergent adverse events (TEAE) was similar in the placebo and filgotinib groups ( approximately 40%). Eight patients on filgotinib and one on placebo had a serious TEAE, and four patients, all of whom received filgotinib, experienced a serious infection. No tuberculosis or opportunistic infections were reported. CONCLUSIONS: Over 24 weeks, filgotinib as monotherapy was efficacious in treating the signs and symptoms of active RA, with a rapid onset of action. Filgotinib was generally well tolerated. TRIAL REGISTRATION NUMBER: NCT01894516.

Filgotinib (GLPG0634/GS-6034), an oral JAK1 selective inhibitor, is effective in combination with methotrexate (MTX) in patients with active rheumatoid arthritis and insufficient response to MTX: results from a randomised, dose-finding study (DARWIN 1).[Pubmed:27993829]

Ann Rheum Dis. 2017 Jun;76(6):998-1008.

OBJECTIVES: To evaluate the efficacy and safety of different doses and regimens of filgotinib, an oral Janus kinase 1 inhibitor, as add-on treatment to methotrexate (MTX) in patients with active rheumatoid arthritis (RA) and inadequate response to MTX. METHODS: In this 24-week phase IIb study, patients with moderate-to-severe active RA receiving a stable dose of MTX were randomised (1:1:1:1:1:1:1) to receive placebo or 50, 100 or 200 mg filgotinib, administered once daily or twice daily. Primary end point was the percentage of patients achieving a week 12 American College of Rheumatology (ACR)20 response. RESULTS: Overall, 594 patients were randomised and treated. At week 12, significantly more patients receiving filgotinib 100 mg once daily or 200 mg daily (both regimens) achieved an ACR20 response versus placebo. For other key end points at week 12 (ACR50, ACR-N, Disease Activity Score based on 28 joints and C reactive protein value, Clinical Disease Activity Index, Simplified Disease Activity Index and Health Assessment Questionnaire-Disability Index), differences in favour of 100 or 200 mg filgotinib daily were seen versus placebo; responses were maintained or improved through to week 24. Rapid onset of action and dose-dependent responses were observed for most efficacy end points and were associated with an increased haemoglobin concentration. No significant differences between once-daily and twice-daily regimens were seen. Treatment-emergent adverse event rates were similar in placebo and filgotinib groups. Serious infections occurred in one and five patients in the placebo and filgotinib groups, respectively. No tuberculosis or opportunistic infections were reported. CONCLUSIONS: Filgotinib as add-on to MTX improved the signs and symptoms of active RA over 24 weeks and was associated with a rapid onset of action. Filgotinib was generally well tolerated. TRIAL REGISTRATION NUMBER: NCT01888874.

Clinical Confirmation that the Selective JAK1 Inhibitor Filgotinib (GLPG0634) has a Low Liability for Drug-drug Interactions.[Pubmed:26693854]

Drug Metab Lett. 2016;10(1):38-48.

OBJECTIVE: The selective Janus kinase 1 inhibitor filgotinib (GLPG0634), which is currently in clinical development for the treatment of rheumatoid arthritis (RA) and Crohn's disease, demonstrated encouraging safety and efficacy profiles in RA patients after 4 weeks of daily dosing. As RA patients might be treated with multiple medications simultaneously, possible drug-drug interactions of filgotinib with cytochrome P450 enzymes and with key drug transporters were evaluated in vitro and in clinical studies. METHODS: The enzymes involved in filgotinib's metabolism and the potential interactions of the parent and its active major metabolite with drug-metabolizing enzymes and drug transporters, were identified using recombinant enzymes, human microsomes, and cell systems. Furthermore, filgotinib's interaction potential with CYP3A4 was examined in an open-label study in healthy volunteers, which evaluated the impact of filgotinib co-administration on the CYP3A4-sensitive substrate midazolam. The potential interaction with the common RA drug methotrexate was investigated in a clinical study in RA patients. RESULTS: In vitro, filgotinib and its active metabolite at clinically relevant concentrations did not interact with cytochrome P450 enzymes and uridine 5'-diphospho-glucuronosyltransferases, and did not inhibit key drug transporters. In the clinic, a lack of relevant pharmacokinetic drug interactions by filgotinib and its active metabolite with substrates of CYP3A4, as well as with organic anion transporters involved in methotrexate elimination were found. CONCLUSION: the collective in vivo and in vitro data on drug-metabolizing enzymes and on key drug transporters, support co-administration of filgotinib with commonly used RA drugs to patients without the need for dose adjustments.
