Fillful-03: A Phase Ⅲ Study of the Efficacy and Safety of Hemay022+Aromatase Inhibitor(AI) in Participants With ER+/HER2+ Advanced or Metastatic Breast Cancer
Study Details
Study Description
Brief Summary
This is a Phase III, randomized, multicenter, 2-arm, open-label clinical trial designed to compare the safety and efficacy of Hemay022+Aromatase inhibitor(AI) with that of capecitabine
- lapatinib in participants with ER+/HER2+ locally advanced or metastatic breast cancer. Participants will be treated until disease progression (PD), unmanageable toxicity, or study termination. Once disease progression is reported, all participants will be followed for survival every 3 months until death, loss to follow-up.

Outcome Measures
Primary Outcome Measures
- Median progression-free survival（mPFS）based on Independent Review Committee (IRC) assessment according to RECIST v1.1 [From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 month]
PFS defined as the proportion of patients alive and without progression
Secondary Outcome Measures
- Overall Survival (OS) of the two group according to RECIST v1.1 [From date of randomization until the date of death from any cause, whichever came first,assessed up to 36 months]
OS is defined as the time from random to any cause of death
- Objective response rate ( ORR, partial response rate+ complete response rate) according to RECIST v1.1 [From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 month]
ORR defined as the proportion of subjects in complete response (CR) or (partial response) PR
- Clinical benefit rate (CBR) according to RECIST v1.1 [From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 month]
Clinical benefit rate defined as percentage of patients with stable disease (SD) ≥ 6 months/partial response (PR)/complete response (CR)
- Duration of Response (DOR) according to RECIST v1.1 [From the first recorded CR or PR until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 month]
DOR defined as the duration after the first assessment as CR or PR, only applicable to subjects who have achieved remission
- Time to Response (TTR) [From date of randomization until the date of the first recorded CR or PR assessed up to 36 month]
TTR defined as the time from random to CR or PR for the first time
