Biological Activity

BMS-986142 potently inhibits human recombinant BTK with an IC50 of 0.5 nM in enzymatic assays. Against a panel of 384 kinases, BMS-986142 is highly selective, with only five other kinases (Tec, ITK, BLK, Txk, BMX) inhibited with <100-fold selectivity for BTK. When Ramos B cells are treated with anti-IgM to activate BCR, BMS-986142 inhibits BTK-dependent calcium flux with an IC50 of 9 nM.

In vivo, serum anti-collagen II IgG titers are significantly inhibited with 10 and 30 mg/kg BMS-986142. BMS-986142 also produces dose-dependent reductions in clinical scores when administration is delayed until the collagen booster on day 21. BMS-986142 doses of 2, 4, and 25 mg/kg in this therapeutic dosing regimen result in clinical score reductions of 17%, 37%, and 67%, respectively, at the end of the study.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
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.
