A Phase 2, Randomized, Double-blind, Placebo-controlled Study to Assess the Safety and Efficacy of Filgotinib and GS-9876 in Female Subjects with Moderately-to-Severely Active Cutaneous Lupus Erythematosus (CLE)

What we are studying

Filgotinib is an orally administered, small molecule inhibitor of JAK1, an intracellular TYK dysregulated in subjects with inflammatory disorders. Filgotinib has demonstrated clinical activity and a favorable safety and tolerability profile in Phase 2 studies in subjects with moderately to severely active RA. Janus kinase 1 activation is required for type I interferon (IFN) signaling, which is thought to be central to both systemic and cutaneous lupus. Further, in vivo studies using a JAK1/JAK2 inhibitor (ruxolitinib) attenuated the development of skin lesions in the MRL/lpr mouse model of lupus. Given its central role in immune cell signaling, inhibition of SYK is expected to have pleiotropic anti-inflammatory effects and affect multiple steps in CLE pathogenesis. B cells have been implicated in the pathogenesis of CLE as demonstrated by an increased number of B cells in the peripheral blood and lesions of individuals with DLE. B cell depletion demonstrates an effect in individuals with certain types of CLE. As a critical mediator of BCR signaling, SYK inhibition suppresses BCR-stimulated proliferation, co-stimulatory molecule expression, and autoantibody production. Phosphorylated SYK and SYK-associated genes are highly expressed in several cell types in CLE skin including keratinocytes and infiltrating immune cells. Further, inhibiting SYK in vitro decreases keratinocyte expression of pro-inflammatory cytokines. Spleen tyrosine kinase inhibition in two lupus-prone mouse models (MRL/lpr and BAK/BAX) suppresses skin disease. The primary objective of this study is as follows: To evaluate the efficacy of filgotinib and GS-9876 in female subjects with moderately-to-severely active cutaneous lupus erythematosus (CLE). The secondary objective of this study is as follows: To evaluate the safety and tolerability of filgotinib and GS-9876 in moderately-to-severely active CLE. The exploratory objectives of this study are as follows: To characterize the pharmacokinetics (PK) of filgotinib and GS-9876 in moderately-to-severely active CLE, To evaluate the effect of filgotinib and GS-9876 on patient-reported outcomes in CLE, including disability and quality of life, To evaluate the effect of filgotinib and GS-9876 on peripheral blood and histologic markers of inflammation, To evaluate the association of inflammatory biomarkers with clinical outcomes, To characterize the association of host genetics and other markers with disease severity, disease progression, and treatment response to filgotinib and GS-9876 in CLE.
