Evaluation of Orally Administered SAR439859 in Japanese Postmenopausal Patients With Advanced Breast Cancer


Brief description of study

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 (HER2-) advanced breast cancer.

Secondary Objectives:

  • 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).

Detailed Study 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.
