Biological Activity

In vitro: ONO-4059 covalently binds to BTK, and reversibly blocks BCR signaling and B-cell proliferation and activation. It has greater selectivity for BTK than Lck, Fyn, LynA and ONO/GS-4059 only inhibits anti-IgM-induced B-cell activation in a concentration-dependent manner but not inhibit anti-CD3/CD28-induced activation of T-lymphocytes from human PBMCs. ONO/GS-4059 inhibits cell proliferation in some malignant B-cell lines but also induces classical apoptosis at nanomolar concentration in the activated-B cell (ABC) DLBCL cell line, TMD8.

In vivo: ONO-4059 demonstrates therapeutic efficacy in a mouse CIA model by suppressing generation of inflammatory chemokines and cytokines including IL-6, IL-8, and TNFα by monocytes, and accompanied by regression of cartilage erosion, bone damage, and pannus formation. In pre-clinical models, and in the clinic in both CLL and NHL patients, It exerts its anti-tumour activity, with a favourable safety profile along with promising efficacy over a long duration.

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.
