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.

Cell Experiment
Cell lines DLBCL cell lines TMD8 cells
Preparation method Cells are treated with idelalisib (420 nM), ONO/GS-4059 (320 nM) or in combination for 48 hours and apoptosis is assessed by FITC Annexin V staining, and measured by flow cytometry.
Concentrations 320 nM
Incubation time 48 h
Animal Experiment
Animal models Male CB17-SCID mice
Formulation 5% (v/v) N-Methyl-2-pyrrolidone (NMP) / 55% (v/v) Polyethylene Glycol 300 (PEG) 300 / 40% (v/v) Water / 1% (w/v) Vitamin E D-α-Tocopherol Polyethylene Glycol 1000 Succinate (TPGS)
Dosages 5 and 10 mg/kg
Administration oral gavage
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.
