Treatment patterns for ESR1-mutated advanced breast cancer

ESR1 Gene MutationAdvanced Breast Cancer

Treatments studied

Part of Cancer clinical trials.

This study looks at how Chinese patients with a specific gene change (ESR1 mutation) in ER-positive, HER2-negative advanced breast cancer are currently being treated. It will help doctors understand what treatments work best for people whose cancer has stopped responding to hormone therapy.

  • You are a woman aged 18 or older who has gone through menopause (either naturally or from surgery).
  • Your breast cancer is advanced (spread to other parts of the body or can't be removed by surgery).
  • Your cancer tests positive for estrogen receptors (ER+), negative for HER2, and has an ESR1 gene mutation.
  • You have already tried at least one type of hormone therapy and your cancer continued to grow.
  • You are not pregnant or breastfeeding, and you can swallow pills easily.

Monitoring ESR1 mutations during first breast cancer treatment

This study is like a safety monitoring program for people with HR+/HER2- advanced breast cancer who are doing well on their first treatment (an aromatase inhibitor plus a CDK4/6 inhibitor). It uses simple blood tests every 3 months to look for ESR1 gene changes that could help guide future care.

Elacestrant and everolimus for ESR1-mutant advanced breast cancer

This trial tests a new combination of two oral targeted therapy pills (elacestrant and everolimus) for people with a specific type of advanced breast cancer. It is for those whose cancer has an ESR1 mutation and has stopped responding to CDK4/6 inhibitors and hormone therapy.

Elacestrant for advanced ER+/HER2- breast cancer with ESR1 mutation

This trial tests an oral drug called elacestrant in women whose ER+/HER2- breast cancer has worsened after at least one hormone therapy. It is for those with a specific genetic change (ESR1 mutation) and advanced or metastatic disease.

Treatment options for HER2-positive advanced breast cancer

This trial tests a sequence of targeted therapy drugs for HER2-positive advanced breast cancer that has spread or cannot be removed by surgery. It aims to see if starting with trastuzumab rezetecan, followed by pyrotinib and trastuzumab plus capecitabine, helps control the cancer.

Maintenance therapy for HER2-positive advanced breast cancer

This trial is testing a new medicine as the first treatment for HER2-positive breast cancer that has spread or cannot be removed. It's for women who have not had chemotherapy for advanced disease.

Study of ESR1 gene changes in blood in advanced breast cancer

This study looks for changes in the ESR1 gene in the blood of people with advanced HR+/HER2- breast cancer. It compares these blood test results with tumor tissue results to learn more about the cancer.
