filgotinib is an approved drug (EMA (2020))
Compound class: Synthetic organic
Comment: Filgotinib is a selective and orally acive JAK1 inhibitor . It is being developed in a collaboration between Gilead Sciences and Galapagos for the treatment of inflammatory indications including psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis and rheumatoid arthritis. It is proposed as a once daily drug, that is predicted to cause fewer toxicity issues and adverse effects than existing JAK1 inhibitors.
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖

|Summary of Clinical Use|
|Filgotinib was advanced to evaluation in patients with rheumatoid arthritis, Crohn's disease and ulcerative colitis. Click here to link to ClinicalTrials.gov's complete listing of filgotinib studies. In October 2019 Gliead Sciences and Galapagos issued a press release which announced sustained efficacy, safety and tolerability of filgotinib from 12-52 weeks in RA patients in the Phase 3 FINCH1 (NCT02889796) & FINCH3 (NCT02886728) trials .
In August 2020, Gilead announed that the FDA had rejected their filing for approval of filgotinib in RA in a complete response letter, that expressed concerns about toxicity (on sperm concentrations) of the 200mg dose. The FDA want to review results from the ongoing MANTA and MANTA-RAy trials that are expected in the first half of 2021. However, late September 2020 saw EMA and Japanese PMDA approvals granted to filgotinib for the treatment of moderate to severe RA.
Publication of results from ulcerative colitis trials is pending, although positive indications (particulary in relation to response rates and safety) were presented at the United European Gastroenterology Week virtual meeting (October 11-13, 2020).
