Brief Summary:
Primary Objective:
To determine whether SAR439859 per 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 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 overall survival in the 2 treatment arms.
- To evaluate the pharmacokinetics of SAR439859 as single agent.
- To evaluate health related quality of life in the 2 treatment arms.
- To evaluate the overall safety profile in the 2 treatment arms.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Breast Cancer Metastatic | Drug: SAR439859 Drug: Endocrine monotherapy as per physician choice | Phase 2 |
The duration of the study for an individual participant will include a period to assess eligibility (screening period) of up to 4 weeks (28 days), a treatment period of at least 1 cycle (28 days of study treatment), and an end of treatment (EOT) visit at least 30 days (or until the participant receive another anticancer therapy, whichever is earlier) following the last administration of study treatment. Study treatment may continue until precluded by unacceptable toxicity, disease progression, death or upon participant's request.

Primary Outcome Measures :
- Progression free survival (PFS) [ Time Frame: Up to 17 months after the first randomized participant ]PFS is defined as the time interval from the date of randomization to the date of documented tumor progression as per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) or death (due to any cause), whichever comes first.
Secondary Outcome Measures :
- Objective Response Rate (ORR) [ Time Frame: Up to 17 months after the first randomized participant ]ORR is defined as the proportion of participants who have a confirmed complete response (CR) or partial response (PR), as best overall response determined by RECIST 1.1 from the date of randomization to the date of end of treatment.
- Disease Control Rate (DCR) [ Time Frame: Up to 17 months after the first randomized participant ]DCR is defined as the proportion of participants who have a confirmed CR, PR, or stable disease (SD) determined by RECIST 1.1 from the date of randomization to the date of end of treatment.
- Clinical Benefit Rate (CBR) [ Time Frame: Up to 17 months after the first randomized participant ]CBR is defined as the proportion of participants who have a confirmed CR, PR, or stable disease (SD) for at least 24 weeks determined by RECIST 1.1 from the date of randomization to the date of end of treatment.
- Duration of Response (DOR) [ Time Frame: Up to 17 months after the first randomized participant ]DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) as determined by objective radiographic disease assessment per RECIST 1.1 or death from any cause, whichever occurs first.
- PFS according to (ESR1) mutation status [ Time Frame: Up to 17 months after the first randomized participant ]PFS as per the estrogen receptor 1 (ESR1) mutation status determined at study entry.
- Overall Survival (OS) [ Time Frame: Up to 35 months after the first randomized participant ]OS is defined as the time interval from the date of randomization to the date of documented death (due to any cause).
- Assessments of the Pharmacokinetic (PK) parameter of SAR439859: Plasma Concentrations [ Time Frame: Day 1 and Day 15 of Cycle 1 and Day 1 of subsequent cycle every 2 cycles upto to 30 days after last study treatment (each cycle is 28 days) ]SAR439859 plasma concentrations.
- Patient Reported Outcome (PRO) - health-related quality of life and health status using the European Quality of Life-5 Dimensions (EQ-5D) [ Time Frame: Day 1 of Cycle 1 and day 1 of subsequent cycle every 2 cycles up to to 30 days after last study treatment (each cycle is 28 days) ]EQ-5D is a standardized measure of health status.
- Patient Reported Outcome (PRO) - the European Organisation for Research and Treatment of Cancer core quality of life questionnaire (EORTC-QLQ-C30) [ Time Frame: Day 1 of Cycle 1 and day 1 of subsequent cycle every 2 cycles up to to 30 days after last study treatment (each cycle is 28 days) ]The EORTC-QLQ-C30 is composed of both multi item scales and single item measures. These include 5 functional scales, 3 symptom scales, a Global Health Status (GHS)/quality of life scale, and 6 single items.
- Patient Reported Outcome (PRO) - EORTC-QLQ breast cancer (EORTC-QLQ-BR23) [ Time Frame: Day 1 of Cycle 1 and day 1 of subsequent cycle every 2 cycles up to to 30 days after last study treatment (each cycle is 28 days) ]The EORTC-QLQ-BR23 contains 23 items: 8 assessing function and 15 items assessing symptoms of disease or treatment.
- Overall safety profile - Treatment-Emergent Adverse events [ Time Frame: Evaluated continuously throughout study from the date of enrollment, up to 30 days after last study treatment administration ]Number of participants with treatment-emergent adverse events (TEAEs).
