Recruiting studies
- NCT05507879Recruiting
Breast cancer heart monitoring to predict heart damage risk
This trial studies how a blood test marker (TRPC6) may help predict and prevent heart muscle damage and heart failure related to some breast cancer medicines. You may join if you’re starting or have received treatment that can stress the heart, or if you already have signs of treatment-related heart problems.
Gainesville, FloridaAges 18 years+ - NCT04144907Recruiting
Protein needs study for colorectal or breast cancer
This study tests how much protein people with colorectal or breast cancer need during treatment or recovery. It may help improve nutrition guidance and support for maintaining health during chemo or after surgery.
Edmonton, AlbertaAges 45–80 - NCT05472792RecruitingPhase 2
Testing breast radiation after lumpectomy with or without hormone pills
This Phase 2 trial compares different “after-surgery” treatment plans for certain older women with hormone-sensitive early breast cancer. It looks at whether a standard hormone-pills approach or a faster, smaller-area radiation approach (given after lumpectomy) works best to prevent cancer coming back.
Chapel Hill, North CarolinaAges 65 years+ - NCT06114108Recruiting
Adding local treatment to drug therapy for stage IV lung cancer
This trial compares continuing drug therapy alone versus adding local treatments (surgery or radiation) for people with stage IV lung cancer that has responded to initial treatment but still has a few remaining spots (oligometastatic). The goal is to see if targeting those spots with local therapy helps control the cancer longer.
AarauAges 18 years+ - NCT05228951RecruitingPhase 2
Testing four breast cancer medicines for stage II–III ER+/PR+/HER2+ cancer
This trial studies a combination of anti-cancer medicines (including trastuzumab and hormone therapy) for women with stage II–III breast cancer that is ER-, PR-, and HER2-positive. It aims to improve outcomes by attacking the cancer in different ways.
Shenyang, LiaoningAges 18–75 - NCT07178171RecruitingPhase 1
QL1706 + short chemo for early triple-negative breast cancer
This trial tests a new immunotherapy drug (QL1706) combined with a short course of common chemotherapy (anthracyclines or taxanes) for people with early-stage triple-negative breast cancer. The goal is to see if this combination is safe and helps shrink the tumor before surgery.
Xi'an, ShaanxiAges 18–70 - NCT07074106RecruitingPhase 2
Lower chemo with tumor-fighting cells for stage I-II breast cancer
This trial tests whether giving less chemotherapy is safe when patients have high levels of tumor-infiltrating lymphocytes (TILs) — a sign that the body's immune system is already fighting the cancer. It is for women with early-stage, triple-negative breast cancer.
BrasíliaAges 18 years+ - NCT06078384RecruitingPhase 2
Pembrolizumab and chemo for early-stage triple-negative breast cancer
This trial studies whether adding pembrolizumab (an immunotherapy) to standard chemotherapy after surgery can improve outcomes for people with early-stage triple-negative breast cancer. The treatment you receive depends on the level of immune cells (TILs) found in your tumor.
AmiensAges 18 years+ - NCT07084558Recruiting
Testing treatment guided by tumor DNA for hormone positive breast cancer
This trial tests whether using a blood test (circulating tumor DNA) can help guide chemo and hormone therapy for early-stage, hormone receptor positive and HER2 negative breast cancer. The goal is to tailor treatment to your tumor's response, potentially reducing unnecessary side effects.
Vienna, AustriaAges 18–100 - NCT06023576RecruitingPhase 2
Blood pressure control during breast cancer chemo
This study tests whether careful blood pressure management can help protect the heart during certain types of chemotherapy (anthracyclines) for breast cancer. Participants will use a smart blood pressure device and may also do an exercise test.
Basking Ridge, New JerseyAges 18 years+ - NCT04983121RecruitingPhase 2
Neoadjuvant pyrotinib plus ARX788 for HER2-positive breast cancer
This Phase 2 trial studies whether combining pyrotinib with ARX788 given before surgery can work better and be safe in people with HER2-positive breast cancer. It’s designed for tumors that did not respond well enough to earlier trastuzumab and pertuzumab treatment.
Shenyang, LiaoningAges 18–75 - NCT02897700RecruitingPhase 1
Testing chemotherapy choices for early breast cancer after surgery
This Phase 1 study tests different chemotherapy approaches in people with breast cancer that has been surgically removed but is early stage. It aims to find a chemotherapy plan that’s safe and works well right after surgery.
Ganzhou, JiangxiAges 18 years+ - NCT07835139Recruiting
Shorter radiation schedule after breast implant reconstruction surgery
This trial compares a shorter course of radiation (fewer, larger doses) with the standard longer course for women who have had breast cancer surgery with implant-based reconstruction. It aims to see if the shorter schedule is just as safe and effective for the chest area, while being more convenient.
ShanghaiAges 18 years+ - NCT07757763Recruiting
Slow jogging for breast cancer survivors
This study looks at whether slow jogging (a gentle form of running) can help breast cancer survivors sleep better. You'll be asked to use a smartphone app to track your activity and sleep, and you may be assigned to a jogging group or a usual-care group.
Taipei, Taipei CityAges 20 years+ - NCT07472803Recruiting
Body composition study in early breast cancer patients
This study looks at how body composition (muscle and fat) changes over time in people with early-stage breast cancer. It aims to better understand the effects of cancer treatment on the body.
New Taipei City, Xindian DistAges 18 years+ - NCT07465393Recruiting
Facility rehab vs home exercise for breast cancer survivors
This trial compares two types of exercise programs for breast cancer survivors to see which one improves quality of life more. You will either attend supervised rehab sessions at a facility or follow a resistance exercise program at home.
New Taipei City, Xindian DistAges 18 years+ - NCT05899387Recruiting
Study fluid after breast surgery
This study looks at a problem called seroma, which is fluid buildup, after certain breast surgeries. It compares different situations where implants or tissue expanders are used, to better understand what to expect and how to manage it.
Augsburg, BavariaAges 18 years+ - NCT07297927Recruiting
Lymphatic imaging before and after radiation for breast cancer
This study uses a special dye and imaging to look at the lymph vessels in your arm before and after radiation therapy. The goal is to understand how radiation affects the lymphatic system, which may help prevent arm swelling in the future.
Hwaseong-si, GyeonggidoAges 18 years+ - NCT07300995Recruiting
Pain coping skills for older women with breast cancer
This study tests a behavioral program to help older women with breast cancer learn skills to cope with pain. The program is done through video or phone sessions.
Durham, North CarolinaAges 55 years+ - NCT06955702Recruiting
Cryotherapy to Prevent Eyelash Loss from Chemo
This trial tests if cooling the eyelids during chemotherapy can prevent eyelash loss in women with newly diagnosed breast cancer. It is for those who have not yet started treatment.
Santander, CantabriaAges 18 years+ - NCT05494502Recruiting
Nerve block to reduce long-term pain after breast surgery
This trial tests whether a specific pain-numbing nerve block given during mastectomy can reduce chronic (long-lasting) pain after breast cancer surgery. It may help some people use less pain medicine later by lowering nerve-related pain after surgery.
Beijing, Beijing MunicipalityAges 18–85 - NCT06336928Recruiting
Blood test validation for breast cancer diagnosis
This study is testing a new blood test (liquid biopsy) to see if it can accurately detect breast cancer or track remission. If you are a woman getting a mammogram, have an abnormal finding, were recently diagnosed, or are in remission after treatment, you may be able to join and help validate this test.
Los Angeles, CaliforniaAges 18 years+ - NCT05723250Recruiting
Rural early cancer care coaching and education program
This study tests an educational “care coordination” program to help people living in rural Vermont manage care during the early stages of breast, lung, or colon cancer treatment. It may help you feel more supported and organized while starting or preparing for chemotherapy.
Burlington, VermontAges 18 years+ - NCT05684367Recruiting
Exercise program to rebuild stamina and energy after breast cancer
This study tests whether a structured exercise program can help older adults with breast cancer regain stamina and reduce fatigue. It focuses on people who are still dealing with moderate fatigue after finishing certain breast cancer treatments.
