Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study LAE205INT3101 is a Phase Ib/III study to evaluate the efficacy and safety of the combination therapy with afuresertib plus fulvestrant (afuresertib/placebo plus fulvestrant in Phase III) in patients with HR+/HER2- breast cancer who have failed 1 to 2 prior lines of endocrine therapy, and/or CDK4/6 inhibitor (up to 1 therapy), and/or chemotherapy (up to 1 chemotherapy) as described in the inclusion criteria.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eligible patients for this study must have either (1) progressive disease whilst receiving an endocrine therapy (AI or a SERM), and/or a CDK4/6 inhibitor for locally advanced or metastatic disease; or (2) relapsed with metastatic disease whilst receiving an ET (AI or SERM), and/or a CDK4/6 inhibitor, and/or chemotherapy in adjuvant setting. No more than 2 prior lines of systemic treatments for locally advanced or metastatic disease are allowed for this study, including 1-2 prior lines of endocrine therapy, with/without CDK4/6 inhibitor (up to 1 therapy), and/or chemotherapy (up to 1 therapy).

5. HR+/HER2- BC patients must meet all the following criteria to join this study:

1. Relapsed locally advanced (LABC) or metastatic (mBC) disease; AND
2. Have received 1 to 2 prior lines of systemic treatments for LABC or mBC(at least one line was ET). If disease relapse during adjuvant therapy or relapse within 12 months from completion of adjuvant endocrine therapy, the adjuvant therapy will be counted as 1 line), including:
