- Data published in Molecular Cancer Therapeutics describes the scientific background underlying the design, discovery and optimization of palazestrant (OP-1250)
- Pre-clinical results demonstrate that palazestrant, as both a
CERAN and a SERD, has a highly differentiated mechanism of action as a potential therapy for advanced ER+/HER2- breast cancer
“The research described in this paper reviews the deliberate design and processes used in discovering and optimizing palazestrant as a molecule purpose-built to address a crucial unmet need in the treatment of women’s cancers, and we are delighted that Molecular Cancer Therapeutics has featured our work,” said
As part of the discovery and optimization process, palazestrant was assessed across an extensive series of biochemical, cell culture, and in vivo assays comparing it with other antiestrogens and compounds that are either approved for use by the FDA or are currently in clinical development, including aromatase inhibitors, selective ER modulators (SERMs), traditional SERDs, and proteolysis-targeting chimeras (PROTACs). As a

About Palazestrant (OP-1250)
Palazestrant (OP-1250) is a novel, orally-available small molecule with dual activity as both a complete estrogen receptor (ER) antagonist (CERAN) and selective ER degrader (SERD). It is currently being investigated in patients with recurrent, locally advanced or metastatic ER-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer. In clinical studies, palazestrant completely blocks ER-driven transcriptional activity in both wild-type and mutant forms of metastatic ER+ breast cancer and has demonstrated anti-tumor efficacy along with attractive pharmacokinetics and exposure, favorable tolerability, CNS penetration, and combinability with CDK4/6 inhibitors. Palazestrant has been granted
