生物活性

Pralsetinib (BLU-667) is a highly potent, selective RET inhibitor. Pralsetinib (BLU-667) inhibits WT RET, RET mutants V804L, V804M, M918T and CCDC6-RET fusion with IC50s of 0.4, 0.3, 0.4, 0.4, and 0.4 nM, respectively[1].

IC50 & Target

IC50: 0.4 nM (Wild type RET), 0.3 nM (RET V804L), 0.4 nM (RET V804M), 0.4 nM (RET M918T), 0.4 nM (CCDC6-RET)[1]

体外研究
(In Vitro)

Pralsetinib (BLU-667) demonstrates more than 10-fold increased potency over approved MKIs against oncogenic RET variants and resistance mutants[1].
Pralsetinib (BLU-667) demonstrates potent activity (IC50=0.4 nM) against common oncogenic RET alterations, including RET M918T, an activating mutation found in MTC, as well as the CCDC6-RET fusion observed in PTC and NSCLC[1].
Pralsetinib (BLU-667) suppresses RET pathway signaling in a panel of RET-driven cell lines: LC2/ad (CCDC6-RET, NSCLC), MZ-CRC-1 (RET M918T, MTC), and TT (RET C634W, MTC)[1].

体内研究
(In Vivo)

Pralsetinib (BLU-667) potently inhibits growth of NSCLC and thyroid cancer xenografts driven by various RET mutations and fusions without inhibiting vascular endothelial growth factor receptor 2 (VEGFR-2)[1].
Pralsetinib (BLU-667) shows dose dependent activity against both KIF5B-RET Ba/F3 and KIF5B-RET V804L Ba/F3 allograft tumors with doses as low as 10 mg/kg twice-daily[1].

Cell Assay
[2]

KIF5B-RET Ba/F3 cells are exposed to compound concentrations ranging from 25 µM to 95.4 pM for 48 hours, and proliferation is assessed with Cell Titer Glo. TT, MZ-CRC-1, TPC-1 or LC2/ad cells are exposed to compound for 4 days and proliferation is measured by BrdU incorporation[2].

Animal Administration
[2]

Mice[2]

BALB/c nude mice are inoculated subcutaneously into the right flank with KIF5B-RET Ba/F3 cells, KIF5B-RET V804L Ba/F3 cells, or TT cells. For all experiments, mice are dosed twice-daily with vehicle, 3 mg/kg, 10 mg/kg, or 30 mg/kg Pralsetinib (Blu667) or once-daily with 60 mg/kg Pralsetinib (Blu667; administered orally) or 60 mg/kg XL184[2].
