Direct and indirect inhibition of the JAKs has demonstrated rapid and sustained improvement in clinical measures of disease. Baricitinib phosphate (INCB 028050) is a selective JAK1 and JAK2 inhibitor.

In vitro: Baricitinib phosphate is a selective orally bioavailable JAK1/JAK2 inhibitor with nanomolar potency against JAK1 (5.9 nM) and JAK2 (5.7 nM) and ~10-fold selective versus JAK3 and Tyk2, no inhibition to c-Met and Chk2. INCB028050 inhibits intracellular signaling of multiple proinflammatory cytokines including IL-6 and IL-23 at concentrations, 50 nM [1].

In vivo: Significant efficacy was achieved in the rat adjuvant arthritis model with doses of Baricitinib phosphate providing partial and/or periodic inhibition of JAK1/JAK2 and no inhibition of JAK3. Baricitinib phosphate was also effective in multiple murine models of arthritis, with no evidence of suppression of humoral immunity or adverse hematologic effects [2].

Clinical trial: Several clinical trials have been conducted to investigated the PK, efficacy and DDI of Baricitinib phosphate in healthy people as well as in participants With Rheumatoid Arthritis.
