Brief Summary:

Primary Objective:

To assess the incidence rate of dose-limiting toxicity and to confirm the recommended dose as well as the maximum tolerated dose of SAR439859 administered as monotherapy to Japanese postmenopausal women with estrogen receptor positive and human epidermal growth factor receptor 2-negative advanced breast cancer.

Secondary Objective:

  • To characterize the overall safety profile of SAR439859 administered as monotherapy.
  • To characterize the pharmacokinetic profile of SAR439859 administered as monotherapy.
  • To evaluate the antitumor activity of SAR439859 administered as monotherapy and the clinical benefit rate (complete response, partial response and stable disease ≥ 24 weeks).

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: SAR439859 Phase 1

Detailed Description:
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 receives another anticancer therapy, whichever is earlier) following the last administration of study treatment. Study treatment may continue until precluded by unacceptable toxicity, disease progression, or upon participant's request.

Route of administration: Oral





Primary Outcome Measures :
  1. Investigational medicinal product (IMP)-related dose limiting toxicities (DLTs) [ Time Frame: Day 1 to Day 28 ]
    Incidence rate of study treatment-related DLTs at Cycle 1


Secondary Outcome Measures :
  1. Safety: Adverse Events (AEs) [ Time Frame: Up to 30 days after administration of study treatment ]
    Number of adverse events related to study therapy

  2. Assessment of Pharmacokinetic parameter of SAR439859: tlag [ Time Frame: Day 1 and Day 22 of Cycle 1 (28 days) ]
    Lag time, interval between administration time and the sampling time preceding the first concentration above the lower limit of quantification

  3. Assessment of Pharmacokinetic parameter of SAR439859: tmax [ Time Frame: Day 1 and Day 22 of Cycle 1 (28 days) ]
    First time to reach Cmax

  4. Assessment of Pharmacokinetic parameter of SAR439859: Cmax [ Time Frame: Day 1 and Day 22 of Cycle 1 (28 days) ]
    Maximum concentration observed

  5. Assessment of Pharmacokinetic parameter of SAR439859: AUC0-24h or AUC0-10h and/or AUC0-12h [ Time Frame: Day 1 and Day 22 of Cycle 1 (28 days) ]
    Area under the plasma concentration versus time curve over the dosing interval (24 hours, 10 hours or 12 hours)

  6. Assessment of Pharmacokinetic parameter of SAR439859: Ctrough [ Time Frame: Day 1, Day 8, Day 15 and Day 22 of Cycle 1 (28 days) and Day 1 of Cycle 2 ]
    Plasma concentration observed just before treatment administration during repeated dosing

  7. Assessment of antitumor activity: Objective response rate (ORR) [ Time Frame: 64 weeks ]
    Objective response rate (ORR) as per Response Evaluation Criteria in Solid Tumors (RECIST 1.1)

  8. Assessment of antitumor activity: Clinical benefit rate (CBR) [ Time Frame: 64 weeks ]
    Clinical benefit rate is (CR [complete response] +PR [partial response] +SD [stable disease] ≥24 weeks) as per RECIST 1.1

  9. Assessment of antitumor activity: Duration of response [ Time Frame: 64 weeks ]
    Response duration defined as the time from initial response to the first documented tumor progression

  10. Assessment of antitumor activity: Non-progression rate [ Time Frame: 64 weeks ]
    Non-progression rate at 24 weeks (percentage of participants without progression at 24 weeks)
