Recruiting studies
- NCT04025164Recruiting
Shorter vs standard breast radiation after lumpectomy
This study compares a shorter course of radiation to a standard longer course after breast-conserving surgery (lumpectomy). It’s meant to see which schedule works just as well while focusing on safety and cancer control.
Guiyang, GuizhouAges 18–70 - NCT05978648RecruitingPhase 2
Trilaciclib for early-stage HR-negative breast cancer after surgery
This trial tests if adding trilaciclib to standard chemotherapy after surgery can help people with hormone receptor-negative breast cancer. It aims to reduce side effects and improve treatment outcomes.
Guangzhou, GangdongAges 18 years+ - NCT04428528Recruiting
Ultrasound-like pictures that track breast tumors during chemotherapy
This study uses a special light-based imaging scan to learn more about breast masses and how tumors may respond to chemotherapy before surgery. The scan is meant to help doctors better characterize tumors and potentially track treatment response.
Toronto, OntarioAges Any age - NCT07297667RecruitingPhase 1
CAR T-cell therapy for certain advanced solid tumors
This trial tests a new treatment called GCAR1, which uses your own immune cells (T-cells) to find and attack cancer cells that have a specific marker called GPNMB. It is for people with certain advanced solid tumors that have not responded to other treatments. The goal is to see if this therapy can help shrink or control the tumor.
Calgary, AlbertaAges 15 years+ - NCT06598046RecruitingPhase 2
Utidelone and Capecitabine for triple-negative breast cancer brain metastases
This trial tests a combination of two chemotherapy drugs (Utidelone and Capecitabine) for people with triple-negative breast cancer that has spread to the brain. The goal is to see if the combination can shrink or control the brain tumors.
Zhengzhou, HenanAges 18 years+ - NCT06184750RecruitingPhase 2
Finding the best tamoxifen dose to lower breast cancer risk
This trial tests different doses of tamoxifen to find the best one for lowering breast cancer risk in premenopausal women. It aims to see if a lower dose works as well as the standard dose with fewer side effects.
Tucson, ArizonaAges 18–55 - NCT07321015RecruitingPhase 2
Fluzoparib after platinum for advanced triple-negative breast cancer
This trial tests the PARP inhibitor fluzoparib as a maintenance treatment for women with advanced triple-negative breast cancer whose disease responded or stabilized after platinum-based chemotherapy. The goal is to see if taking fluzoparib daily can delay cancer growth.
TianjinAges 18–75 - NCT07287917RecruitingPhase 1/Phase 2
Testing a new drug combo for advanced breast cancer or melanoma
This trial tests a new combination of drugs (AMXT 1501, DFMO, and standard therapies) for people with advanced solid tumors, specifically breast cancer (ER+ HER2-) or melanoma that has progressed after other treatments. The goal is to see if this combination can help shrink tumors or slow their growth.
Tucson, ArizonaAges 18 years+ - NCT06081244RecruitingPhase 3
Testing sacituzumab govitecan with or without pembrolizumab for early triple-negative breast cancer
This trial tests a two-drug combination (sacituzumab govitecan and pembrolizumab) versus sacituzumab govitecan alone before surgery for low-risk, triple-negative breast cancer that hasn't spread. The goal is to see which approach works better at shrinking tumors.
Baden-Baden, Baden-WurttembergAges 18 years+ - NCT04923542RecruitingPhase 1/Phase 2
Targeted drug plus focused brain radiation for breast cancer
This study tests whether abemaciclib (a targeted pill) given with focused radiation to brain tumors can control hormone receptor–positive, HER2-negative breast cancer in the brain. It’s designed to see if the combination helps shrink or slow the growth of brain metastases while keeping side effects manageable.
Tampa, FloridaAges 18 years+ - NCT06028022RecruitingPhase 2
Reishi mushroom for fatigue and joint/muscle pain in breast cancer
This trial tests whether a reishi mushroom extract can help reduce fatigue and joint or muscle pain in people with breast cancer who are taking aromatase inhibitors. If you have these symptoms, you may be able to join.
Albert Lea, MinnesotaAges 18 years+ - NCT06992336RecruitingPhase 2
Circulating tumor DNA guided extra treatment for early triple-negative breast cancer
This trial tests whether using a blood test to detect leftover cancer DNA after initial treatment can help doctors decide if extra therapy is needed for people with early triple-negative breast cancer. It aims to improve outcomes for those with remaining disease after neoadjuvant therapy.
Guangzhou, GuangodngAges 18–70 - NCT05973864RecruitingPhase 2
Capecitabine plus pembrolizumab after TNBC surgery and chemo
This Phase 2 trial studies whether adding capecitabine to pembrolizumab after surgery can lower the risk of cancer coming back in people with triple-negative breast cancer that didn’t fully respond to earlier treatment. It’s meant for patients whose tumor was removed but still showed remaining cancer after chemo-immunotherapy.
AmiensAges 18 years+ - NCT07467330RecruitingPhase 3
Breast cancer trial: Adding capecitabine to standard treatment
This trial tests if adding a chemotherapy drug called capecitabine to the combination of dalpiciclib and hormone therapy works better than dalpiciclib and hormone therapy alone for advanced breast cancer that is hormone receptor-positive and HER2-negative. It is for people who have not had these treatments before.
Fuzhou, FujianAges 18 years+ - NCT06382818Recruiting
Personalized breast radiation based on risk and side effects
This trial tests whether radiation therapy can be personalized based on your risk of the cancer coming back and your risk of side effects from radiation. Depending on those factors, you may receive a tailored radiation plan that could be more or less intense.
MontpellierAges 18 years+ - NCT05451784RecruitingPhase 1/Phase 2
PD-1 TIL therapy for advanced triple-negative breast cancer
This study tests an immune-cell treatment made from your tumor tissue. It aims to help people with advanced or metastatic triple-negative breast cancer by collecting PD-1–positive immune cells and giving them back after treatment.

ctDNA-guided immunotherapy boost after chemotherapy for triple-negative breast cancer
This Phase 2 study checks whether a blood test that looks for cancer DNA (ctDNA) can help decide who should get an extra 12-month immunotherapy treatment after standard chemotherapy and surgery. It may help reduce the chance of the cancer coming back in people with triple-negative breast cancer.
Guandong, GuangdongAges 18–80 - 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.
