Newport Beach, CaliforniaAges 18 years+ - NCT04614194RecruitingPhase 2
Blood and tumor markers to test response to abemaciclib
This trial studies how the immune system and other body signals in blood and tumor tissue relate to how well abemaciclib works before breast cancer surgery. The goal is to learn who benefits most from this medicine and why.
Dallas, TexasAges 18 years+ - NCT04803539RecruitingPhase 2/Phase 3
ctDNA-guided booster treatment after chemo for triple-negative breast cancer
This trial uses a blood test called ctDNA to see who is at higher risk after surgery and standard chemotherapy for triple-negative breast cancer. If your ctDNA test is positive, you may receive an extra “boost” treatment to help reduce the chance the cancer returns.
Guandong, GuangdongAges 18–80 - NCT05037825Recruiting
Study gut microbes with immune therapy in several solid cancers
This trial looks at how the gut microbiome (the bacteria in your digestive system) relates to outcomes when you take standard immune “checkpoint” cancer medicines. If you’re eligible, they’ll collect stool samples while you receive treatment for certain cancers.
Elizabethtown, KentuckyAges 18 years+ - NCT05217966Recruiting
Radiation before possible breast surgery for early ER-positive cancer
This study gives radiation to the breast before surgery to see if some people can safely delay or even skip surgery. It targets women with a small, node-negative, ER-positive breast cancer with low genetic risk.
Montreal, QuebecAges 50 years+ - NCT05366699Recruiting
Procedure to help prevent arm swelling after breast surgery
This trial studies a new procedure meant to lower the chance of getting lymphedema (arm swelling) after breast cancer surgery that removes lymph nodes in the armpit. It may help patients reduce the risk of long-term arm swelling, especially after lymph node dissection.
San Francisco, CaliforniaAges 18–75 - NCT05496829Recruiting
Improving how people take breast-cancer and heart medicines
This trial tests an intervention to help improve how equitably people take their prescribed breast cancer hormone therapy and heart-related prevention medicines. It may help if you have had trouble taking these medications as directed.
