In vitro

Avapritinib (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 its activity 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.

In vivo

In vivo, Avapritinib (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 this compound 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, it 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.
