Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Hormone Receptor Positive Breast Carcinoma HER2-negative Breast Cancer Drug: OP-1250 Phase 1 Phase 2

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.

Arm Intervention/treatment
Experimental: OP-1250 Dose Escalation
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
Drug: OP-1250
Complete Estrogen Receptor ANtagonist (CERAN)

Experimental: OP-1250 Expansion
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
Drug: OP-1250
Complete Estrogen Receptor ANtagonist (CERAN)




Primary Outcome Measures :
  1. Determine MTD and/or RP2D of OP-1250 when used as a single agent [ Time Frame: Up to one year ]
    Number of patients with DLT as defined in the protocol
