HPK1-IN-7 is a potent, orally active HPK1 (hematopoietic progenitor kinase 1, MAP4K1) inhibitor (IC50=2.6 nM) with excellent family and kinome selectivity. HPK1-IN-7 shows selectivity against IRAK4 (59 nM) and GLK (140 nM). HPK1-IN-7 shows robust efficacy against MC38 syngeneic tumor model in combination with anti-PD1[1].
HPK1-IN-7 (100 mg/kg; p.o.; twice daily for 28 days) shows robust enhancement of anti-PD1 efficacy in a syngeneic tumor model of colorectal cancer[1].
HPK1-IN-7 (compound 24) (1 mg/kg; intravenous; mice) is characterized by moderate plasma clearance (43 mL/min/kg) and a large volume of distribution (4.4 L/kg). After oral administration (20 mg/kg), the Cmax was 5.3 μM and the AUC0-24h was 19 μM•h. The calculated oral bioavailability based on these pharmacokinetics studies is approximately 100%[1].
