We aimed to evaluate the pharmacodynamics, efficacy, safety and tolerability of the JAK1 inhibitor GSK2586184 in adults with systemic lupus erythematosus (SLE). Oral tofacitinib has been approved for the treatment of rheumatoid arthritis (RA) in the US and is in clinical development for the treatment of other autoimmune diseases. Janus kinase inhibitors have become promising treatment modalities for conditions such as psoriasis, atopic dermatitis, alopecia areata, and vitiligo. A selective JAK1 inhibitor may avoid side effects related to the mode of action of pan-JAK inhibitors, and therefore may be effective in treatment of SLE.
