Background

IC50: 0.82, 0.14 and 0.28 nM for ERα binding, ERα downregulation, ERα antagonism, respectively

AZD9496 is an orally active estrogen receptor inhibitor.

Estrogen receptors (ERs) are a group of proteins presented inside and on cells, and they are receptors that are activated by the hormoneestrogen. ERs are found to be over-expressed in about 70% of breast cancer cases, referred to as "ER-positive".

In vitro: AZD9496 was identified as a nonsteroidal small-molecule inhibitor of ERα, which was a potent and selective antagonist and downregulator of ERα. In addition, AZD9496 could bind and downregulate clinically relevant ESR1 mutants [1].

In vivo: Animal study reported that significant tumor growth inhibition was observed as low as 0.5 mg/kg dose of AZD9496 in the estrogen-dependent MCF-7 xenograft model, and such effect was accompanied by a dose-dependent decrease in PR protein levels, providing potent antagonist activity. In addition, the combination of AZD9496 with PI3K pathway and CDK4/6 inhibitors resulted in further growth-inhibitory effects when compared with monotherapy alone. Furthermore, the tumor regression was also observed in a long-term estrogen-deprived breast model, in which significant ERα protein downregulation was found [1].

Clinical trial: AZD9496 is currently being evaluated in a phase I clinical trial to assess the PK and safety of different forms and formulations [2].

Protocol

Cell experiment:

Effect of AZD9496, Fulvestrant, and Tamoxifen on ERα peptide turnover in MCF-7 cells. Cells are grown in steroid-free conditions in SILAC media containing 13C615N4 L-arginine to label ERα peptide as “heavy” (blue line) and then switched to grow in media containing unlabeled L-arginine to label newly synthesized protein as “normal” (red line) with 0.1% DMSO, 300 nM Tamoxife, 100 nM AZD9496, or 100 nM Fulvestrant for the time indicated. Data shown is representative of two independent experiments[1].

Animal experiment:

Mice[1] In vivo efficacy of AZD9496 in MCF-7 xenograft model. MCF-7 xenografts, grown in male SCID mice, are dosed daily with either PEG/captisol (vehicle) or AZD9496 (0.02, 0.1, 0.5, 10, and 50 mg/kg, p.o., q.d.). Tumor growth is measured by caliper at regular intervals and mean tumor volumes plotted for each dosed group.
