Quality Control
Biological Activity

In vitro: The compound covalently bonds to BTK, inhibiting BCR signaling and B-cell proliferation and activation. NO/GS-4059 induced durable responses in relapsed/refractory B-cell malignancies without significant toxicities. In vivo: ONO-4059 demonstrated therapeutic efficacy in a mouse arthritis model, and based on its anti-proliferative activity in B-cells.

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.
