Purpose

This clinical trial is a Phase 1-2, open-label, multi-center, dose-escalation and expansion study evaluating the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of daily oral administration of OP-1250.

Detailed Description

      OP-1250 is a small molecule Complete Estrogen Receptor ANtagonist (CERAN). OP-1250 potently
      competes with the endogenous activating estrogenic ligand 17-beta estradiol for binding in
      the ligand binding pocket. OP-1250 blocks estrogen-driven transcriptional activity, inhibits
      estrogen-driven breast cancer cell growth, and induces degradation of the estrogen receptor.
