Testing a new drug for advanced ER-positive breast cancer
This trial tests an experimental oral drug (FWD1802) for women with a specific type of advanced breast cancer (ER-positive, HER2-negative) that has stopped responding to hormone therapy. It looks at whether the drug can slow or stop cancer growth, especially if you have an ESR1 mutation.
Hefei, AnhuiAges 18 years+ - NCT06085742RecruitingPhase 2
CMC chemotherapy for early stage breast cancer
This trial tests a chemotherapy combination (CMC) for people with early-stage, hormone receptor-positive, HER2-negative breast cancer who have a high risk of recurrence. It aims to understand if this oral regimen is effective and tolerable.
Chicago, IllinoisAges 18 years+ - NCT06087120Recruiting
Can a blood test predict breast cancer treatment response?
This study looks at whether a blood test (ctDNA) can help predict how well breast cancer responds to chemotherapy before surgery. It focuses on people with HER2-positive or triple-negative breast cancer that has not spread far.
JakartaAges 18 years+ - NCT06150898RecruitingPhase 2
Ketorolac and pregabalin for estrogen receptor positive breast cancer before surgery
This trial tests whether two medications, ketorolac (a pain reliever) and pregabalin (a nerve pain drug), can help treat estrogen receptor (ER) positive breast cancer when taken before surgery. It may offer better pain control and possibly improve cancer outcomes.
