Study of PET imaging and blood tests for ER+ HER2- metastatic breast cancer
This trial tests a new imaging technique (18F-FES PET/CT) along with blood markers to guide treatment for metastatic breast cancer that is ER-positive and HER2-negative. It's for people whose cancer progressed on first-line hormone therapy and who are starting a second line of hormone therapy.
BayonneAges 18 years+ - NCT06201234RecruitingPhase 2
Adding elacestrant to olaparib for advanced HR+/HER2- breast cancer
This trial tests if adding a new oral medicine (elacestrant) to a standard PARP inhibitor (olaparib) works better for people with advanced or metastatic HR+/HER2- breast cancer who have a BRCA1 or BRCA2 gene mutation. The goal is to see if the combination can help control the cancer longer.
Stuttgart, Baden-WurttembergAges 18 years+ - NCT06120283RecruitingPhase 1
Study of BGB-43395 alone or with other drugs for advanced solid tumors
This study tests a new drug called BGB-43395 alone or with other treatments for advanced solid tumors, especially breast cancer. The goal is to find the best dose and see how well it works. It may be an option if your cancer has not responded to other treatments.
Denver, ColoradoAges 18 years+ - NCT06106477Recruiting
Intermittent fasting for women with early breast cancer
This trial studies whether a 14-hour night fast and 10-hour eating window can improve inflammation markers and quality of life in women with HR+/HER2- early breast cancer. You would start the fasting routine within three months of beginning hormone therapy.
Milwaukee, WisconsinAges 18 years+ - NCT06058377RecruitingPhase 3
Adding immunotherapy to chemo for stage II-III breast cancer
