An Open Label Randomized Phase 2 Trial of Amcenestrant (SAR439859), Versus Endocrine Monotherapy as Per Physician's Choice in Patients With Estrogen Receptor-positive, HER2-Negative Locally Advanced or Metastatic Breast Cancer With Prior Exposure to Hormonal Therapies
Abstract
Primary Objective:
To determine whether amcenestrant per overall survival (os) improves progression free survival (PFS) when compared with an endocrine monotherapy of the choice of the physician, in participants with metastatic or locally advanced breast cancer
Secondary Objectives:
* To compare the overall survival in the 2 treatment arms
* To assess the objective response rate in the 2 treatment arms
* To evaluate the disease control rate in the 2 treatment arms
* To evaluate the clinical benefit rate in the 2 treatment arms
* To evaluate the duration of response in the 2 treatment arms
* To evaluate the PFS according to the estrogen receptor 1 gene (ESR1) mutation status in the 2 treatment arms
* To evaluate the pharmacokinetics of amcenestrant as single agent
* To evaluate health-related quality of life in the 2 treatment arms
* To compare the overall safety profile in the 2 treatment arms
Conditions: Breast Cancer Metastatic.
Primary outcome: Progression Free Survival (PFS); Chinese Cohort: Progression Free Survival.
Enrollment: 367 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 367 participants or records.
