A Dose Escalation/Expansion Study of Oral OP-1250 in Subjects With Advanced and/or Metastatic HR+, HER2- Breast Cancer

HER2-negative Breast Cancer Clinical Trial

Official title:
A Phase I Dose Escalation and Dose Expansion and Phase II Monotherapy Open-label, First-in-Human, Multicenter Study of OP-1250 in Adult Subjects With Advanced and/or Metastatic Hormone Receptor (HR)-Positive, HER2-negative Breast Cancer

Clinical Trial Summary

This clinical trial is a Phase I dose escalation and dose expansion and Phase II monotherapy open-label, first-in-human, multicenter study of OP-1250 in adult subjects with advanced and/or metastatic hormone receptor (HR)-positive, her2-negative breast cancer.

Clinical Trial Description

This is a Phase I dose escalation and dose expansion and Phase II monotherapy open--label, first--in--human study to determine the dose limiting toxicity (DLT), maximum tolerated dose (MTD) and/or recommended Phase II dose (RP2D), to characterize the safety and pharmacokinetic (PK) profile, and to estimate the preliminary anti-tumor activity of OP-1250 as a single agent in adult subjects with hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative metastatic or locally advanced breast cancer. This study comprises 2 Phases: Phase I (Part A [Dose Escalation] and Part B [Dose Expansion]) and Phase II. Additionally, all subjects (Phase I and Phase II) will be eligible to participate in 1 of 2 sub-studies. Patients must have received at least 1 prior hormonal regimen and at least 6 months of a prior continuous endocrine therapy for locally advanced or metastatic disease. Patients will be evaluated for treatment emergent adverse events (AEs) during study participation, and toxicity will be assessed according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events, Version 5.0. ;
