Brilanestrant (ARN-810; GDC-0810) is an orally bioavailable selective estrogen receptor degrader (SERD) with IC50 of 0.7 nM.
Brilanestrant (ARN-810; GDC-0810) is a potent ER-α binder (IC50=6.1 nM), a full transcriptional antagonist with no agonism (3× ERE, IC50=2 nM), and displays good potency and efficacy in ER-α degradation (EC50=0.7 nM) and MCF-7 breast cancer cell viability (IC50=2.5 nM) assays[1].Brilanestrant (ARN-810; GDC-0810) induces a distinct ERα conformation versus tamoxifen and other ER therapeutics, and does not exhibit tamoxifen-like ER agonism in MCF7 cells[2].
The pharmacokinetic profile of Brilanestrant (ARN-810) shows it is a olw clearance molecule across species, with good bioavailability (40%-60%). Brilanestrant (ARN-810) (3 mg/kg, p.o.) shows substantial tumor-growth inhibition in a tamoxifen-sensitive MCF-7 xenograft model, while at the highest dose of 100 mg/kg/day, all animals show tumor regression of more than 50% without weight loss[1].Brilanestrant (ARN-810) exhibits low clearance (11 mL/min/kg) and 61% oral bioavailability. Brilanestrant (ARN-810) (1-100 mg/kg/day, p.o.) displays dose dependent efficacy in the MCF7 xenograft model[2].
