Biological Activity

Firibastat (QGC001) is an orally active EC33 precursor drug. Firibastat is A first-in-class (first-in-class) brain aminopeptidase A (APA) inhibitor (Ki=200 nM) that selectively and specifically inhibits the conversion of cerebral angiotensin II to angiotensin III and lowers blood pressure in hypertensive rats.

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.
