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.
| Name | Type | Description | Interventions |
|---|---|---|---|
| OP-1250 Dose Escalation | Experimental | This portion of the study will evaluate the safety and pharmacology of a range of OP-1250 doses administered daily in subjects with advanced and/or metastatic hormone receptor (HR)-positive, HER2-negative breast cancer and to determine the RP2D |
|
| OP-1250 Expansion | Experimental | This portion of the study further explores the clinical activity, safety and pharmacology of OP-1250 monotherapy at the RP2D and to estimate preliminary data of anti-tumor efficacy |
