Summary

This trial is testing a new drug to see if it can improve survival in patients with metastatic breast cancer.

Who is the study for?
This trial is for men and women over 18 with AR+/ER+/HER2- metastatic breast cancer who've had at least two prior treatments, including an AI and fulvestrant with a CDK 4/6 inhibitor. Participants must have measurable disease, respond well to past treatments, and not be pregnant or planning pregnancy. Men must use contraception; women must be non-childbearing or agree to contraception.
What is being tested?
The trial tests the effectiveness of Enobosarm alone in treating specific metastatic breast cancer by monitoring how long patients live without their disease getting worse on scans. It's for those whose tumors are positive for certain receptors and who've previously responded to treatment.
What are the potential side effects?
While the side effects of Enobosarm aren't detailed here, common ones may include fatigue, nausea, changes in liver function tests, hormonal imbalances like testosterone increase or decrease which could affect mood or libido.

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
Pivotal Trial
The final step before approval, pivotal trials feature drugs that have already shown basic safety & efficacy.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Enobosarm Treatment GroupExperimental Treatment1 Intervention
Subjects in the Enobosarm Treatment Group will receive enobosarm 9mg each day by mouth until disease progression or an unacceptable adverse event is observed. The total duration of the study for a subject in the study from screening to follow-up visit is not standardized and will be different for each subject.
Group II: Control Treatment GroupActive Control1 Intervention
Subjects in the Control Treatment Group will receive an ER targeted therapy limited to exemestane monotherapy, exemestane plus everolimus or selective estrogen receptor modulator (SERM) approved for the treatment of breast cancer and is part of the standard of care at the clinical study site. The decision of which comparator treatment will be used will be made prior to randomization. After radiographic progression, subjects randomized to the Control Treatment Group may be crossed over to receive enobosarm 9mg.
