Biological Activity

In vitro: Beyond ALK, IGF1R, and InsR, brigatinib also potently inhibits FLT3 and ROS1 with IC50 values of 2.1 and 1.9 nM, respectively. It does not show significant activity toward c-Met or Ron up to 1 μM. Brigatinib overcomes the resistance of EGFR-triple-mutant and the activity depends on ATP-competitive manner with less affection to wild-type EGFR. In vivo: Mouse PK parameters for Brigatinib following oral dosing (10 mg/kg): Cmax=448 ng/mL,t1/2=5.8 h. And in CD rats, after dosing at 3 mg/kg i.v, CL=0.46 L/(h·kg), t1/2=4.8 h, Vss=7.8 L/kg; Dosed at 10 mg/kg p.o, Cmax=305 ng/mL, tmax=4 h, t1/2=3.4 h, F%=52. Brigatinib demonstrates dose-dependent antitumor activity. Brigatinib demonstrates growth inhibition activity in PC9 triple-mutant xenograft model and in combination with anti-EGFR antibody to potentiate the efficacy both in vitro and in vivo as shown in first-generation EGFR-TKI-resistant patients.

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

Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 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 resveratrol of 11.2 mg/kg.
