Official title

A Open-label, Randomized, Multicenter Phase III Study of ESG401 Versus Investigator's Choice Chemotherapy in Patients With Locally Advanced or Metastatic HR+/HER2- Breast Cancer Who Had Failed at Least One Line of Chemotherapy

Overview

The aim of this study is to evaluate the efficacy and safety of ESG401 in patients with unresectable locally advanced or metastatic HR+/HER2- breast cancer.

Detailed description

This is a open-label, randomized, multicenter Phase 3 study to evaluate ESG401 versus Treatment of Physician's Choice (TPC) in subjects with unresectable locally advanced or metastatic HR+/HER2- breast cancer who had failed at least one line of systemic chemotherapy.

Interventions

  • Drug ESG401
    IV infusion on day 1,8, and 15 of each 28 day cycle
  • Drug Eribulin, capecitabine, gemcitabine or vinorelbine (Treatment of Physician's Choice)
    Eribulin, capecitabine, gemcitabine or vinorelbine

Primary outcome measures

  • Progression-free survival (PFS) assessed by IRC per RECIST 1.1 [Time frame: Up to 24 months]
Secondary outcome measures (10)
  • Progression-free survival (PFS) assessed by the investigators per RECIST V 1.1 [Time frame: Up to 24 months]
  • Overall Survival (OS) [Time frame: Up to 24 months]
  • Objective Response Rate (ORR) [Time frame: Up to 24 months]
  • Clinical Benefit Rate (CBR) [Time frame: Up to 24 months]
  • Duration of Response (DoR) [Time frame: Up to 24 months]
  • Quality of life evaluated using the NCC-BC-A scale [Time frame: Up to 24 months]
  • Adverse events(AEs) and severe adverse events (SAEs) [Time frame: From signing the ICF up to last dose plus 30 days]
  • Clearance [Time frame: Up to 24 months]
  • Volume of distribution [Time frame: Up to 24 months]
  • ADA [Time frame: Up to 24 months]
