Study Summary
This trial evaluates the activity of a drug (lasofoxifene) to treat pre- and postmenopausal women with advanced breast cancer caused by an ESR1 mutation. It will measure progression free survival, clinical benefit, response rate, overall survival, QoL and safety.
Who is the study for?
This trial is for pre- and postmenopausal women with advanced or metastatic ER+/HER2- breast cancer that worsened on an aromatase inhibitor plus a CDK 4/6 inhibitor. Participants must have specific ESR1 mutations, no more than one prior chemo regimen for metastatic disease, good performance status, and adequate organ function. Women with brain metastasis, recent thrombosis or certain heart conditions are excluded.Check my eligibility
What is being tested?
The study compares the effectiveness of lasofoxifene versus fulvestrant in improving progression-free survival among participants. It's open-label and randomized, meaning both patients and researchers know which treatment is given and patients are assigned to groups by chance.See study design
What are the potential side effects?
Potential side effects include hot flashes, joint pain, nausea, fatigue, increased risk of blood clots (like deep vein thrombosis), vaginal bleeding or discharge due to hormonal changes caused by the treatments.
