Blu-285 is a potent and selective inhibitor for hematologic malignancies with KIT Exon 17 Mutations. BLU-285 has demonstrated biochemical in vitro activity on the KIT exon-17 mutant enzyme, KIT D816V. Cellular activity of BLU-285 on KIT D816 mutants was measured by autophosphorylation in the human mast cell leukemia cell line HMC1.2, and the P815 mouse mastocytoma cell line with IC50= 4 and 22 nM, respectively. In vivo BLU-285 was well tolerated and has demonstrated dose-dependent antitumor efficacy. Complete tumor growth inhibition and ≥ 75% KIT kinase inhibition was observed with 10 mg/kg once daily, oral dosing of BLU-285 in the aggressive KIT exon 17 mutant driven P815 mastocytoma model grown as a solid tumor allograft as well as in a disseminated model of the disease. BLU-285 was also well tolerated in this in vivo model and had no adverse effects on body weight at either dose. — NCATS

Mechanism of action
PDGFRA antagonist
- Stem cell growth factor receptorINHIBITOR
Stem cell growth factor receptor inhibitor
Receptor tyrosine kinases have a role in cell proliferation and are targeted by cancer chemotherapy. Avapritinib inhibits autophosphorylation in KIT D816V and PDGFRA D842V mutants (IC50 of 4 nM and 30 nM, respectively) in vitro and was active in a mouse xenograft model.
Active against PDGFRA and PDGFRA D842 and multiple KIT exon 11, 11/17 and 17 mutants (IC50s < 25 nM). Other potential targets: wild-type KIT, PDGFRB, CSFR1.
Platelet-derived growth factor receptor alpha inhibitor
Receptor tyrosine kinases have a role in cell proliferation and are targeted by cancer chemotherapy. Avapritinib inhibits autophosphorylation in KIT D816V and PDGFRA D842V mutants (IC50 of 4 nM and 30 nM, respectively) in vitro and was active in a mouse xenograft model.
Active against PDGFRA and PDGFRA D842 and multiple KIT exon 11, 11/17 and 17 mutants (IC50s < 25 nM). Other potential targets: wild-type KIT, PDGFRB, CSFR1.
