Rilzabrutinib, also known as PRN1008, is a reversible covalent, selective and oral active inhibitor of Bruton’s Tyrosine Kinase (BTK) with IC50 of 1.3 nM. Cysteine targeting of BTK by Rilzabrutinib results in a slow off-rate demonstrated by retention of 79±2% of binding to BTK in PBMC 18 hours after washing away the compound in vitro. The covalent cysteine binding is completely reversible after denaturation of the target. Anti-IgM induces human B cell proliferation (10% serum) and B cell CD69 expression are inhibited by Rilzabrutinib with IC50 of 5±2.4 nM and 123±38 nM, respectively.

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.
