Biological Activity

Baricitinib (formerly INCB28050, LY3009104) is a selective orally bioavailable JAK1/JAK2 inhibitor. Baricitinib preferentially inhibits JAK1 and JAK2, with 10-fold selectivity over Tyk2 and 100-fold over JAK3. INCB-28050 (baricitinib) inhibits intracellular signaling of multiple proinflammatory cytokines including IL-6 at concentrations <50 nM. Baricitinib also inhibits pSTAT3 stimulated by IL-23 with IC50 of 20 nM in isolated naive T-cells. Baricitinib (INCB028050) was also effective in multiple murine models of arthritis, with no evidence of suppression of humoral immunity or adverse hematologic effects. Baricitinib reduces levels of pSTAT3 in a dose- and time-dependent manner in the peripheral blood of rAIA animals. INCB28050 (Baricitinib) (10 mg/mL, p.o.) improves a composite score of joint damage by 47% in the murine CIA model.

Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
