How to use

In Vitro:

SAR439859 is a novel, orally bioavailable SERD with potent antagonist and degradation activities against both wild-type and mutant Y537S ER. Driven by its fluoropropyl pyrrolidinyl side chain, SAR439859 has demonstrated broader and superior ER antagonist and degrader activities across a large panel of ER+ cells, including inhibition of ER signaling and tumor cell growth.

In Vivo:

SAR439859 shows promising antitumor activity in breast cancer mice xenograft models. In vivo treatment with SAR439859 demonstrates significant tumor regression in ER+ breast cancer models, including MCF7-ESR1 wild-type and mutant-Y537S mouse tumors, and HCI013, a patient-derived tamoxifen-resistant xenograft tumor.
