製品説明 | Avapritinib is a small molecule kinase inhibitor that potently inhibits PDGFRα D842V mutant activity in vitro (IC50 = 0.5 nM) and PDGFRα D842V autophosphorylation in the cellular setting (IC50 = 30 nM); also a potent inhibitor of the analogous Kit (c-Kit) mutation, D816V in Kit (c-Kit) Exon 17 (IC50 = 0.5 nM). |

in vitro | BLU-285 is a selective oral inhibitor that targets KIT Exon 17 and PDGFRα D842 activation loop mutants. Cellular assays measuring inhibition of KIT mutant autophosphorylation confirm the activity of BLU-285 against the KIT D816 mutants D816V (HMC1.2 cells, IC50 = 3 nM) and D816Y (P815 cells, IC50 = 22 nM) as well as other KIT Exon 17 mutants such as N822K (Kasumi cells, IC50 = 40 nM) found in treatment-refractory GIST[1]. |
in vivo | In vivo, BLU-285 is a well-tolerated, orally bioavailable agent that achieves dose dependent tumor growth inhibition in a D816Y-driven xenograft model. A PK-PD-efficacy relationship with BLU-285 has been established demonstrating that tumor regression results from >90% target suppression and is observed with 30 mg/kg once daily dosing. With potent activity against PDGFRα D842V and KIT Exon 17 mutants, BLU-285 targets previously unaddressed genomic drivers of disease and provides promise for the treatment of PDGFRα D842V-driven GIST(gastrointestinal stromal tumor) or SM(systemic mastocytosis), where more than 90% of patients carry the KIT D816V mutation. Besides single agent activity, the highly selective BLU-285 offers an opportunity for combination with other agents in GIST to cover the entirety of KIT primary and resistance mutants[1]. |
