Recruiting studies
- NCT01042379RecruitingPhase 2
Adaptive drug trial for newly diagnosed breast cancer
This study tests personalized, changing treatment plans (given before surgery) to find better options for your specific breast tumor. You may be asked for extra breast-tissue testing to help match you with the most suitable study drug(s).
Birmingham, AlabamaAges 18 years+ - NCT00437879Recruiting
Ultrasound and MRI scans to track breast cancer response early
This study uses ultrasound and/or MRI scans to see how breast cancer responds early while you start “neoadjuvant” treatment (chemotherapy, with or without radiation before surgery). It may help doctors spot response sooner and better understand which imaging changes match treatment benefit.
Toronto, OntarioAges Any age - NCT01185132RecruitingPhase 3
IMRT versus partial-breast radiation after lumpectomy
This study compares two different ways of giving radiation to the breast after lumpectomy for early-stage breast cancer. It may help determine which approach controls the cancer well while reducing radiation to surrounding healthy tissue.
Aurora, ColoradoAges 40 years+ - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT01993498Recruiting
Study side effects of cancer treatment in localized breast or lung cancer
This study looks at long-term side effects from standard cancer treatments and how they affect daily life and resources. It may help improve care for people with breast or lung cancer that has not spread.
VillejuifAges 18 years+ - NCT02338167Recruiting
Study for pregnant women with breast cancer
This study is for adults with breast cancer who are pregnant and are either newly diagnosed (early) or have locally advanced or metastatic disease. It aims to better understand how breast cancer treatment should be managed during pregnancy.
Böblingen, Baden-WurttembergAges 18–99 - NCT00823654Recruiting
Blood tests during treatment to track ovarian egg supply
This study measures blood biomarkers to understand how breast cancer treatment affects a person’s future fertility (ovarian reserve). It may help patients learn more about egg supply changes after chemotherapy and hormone-related treatments.
Basking Ridge, New JerseyAges 18–44 - NCT07400523RecruitingPhase 3
Ribociclib for breast cancer with leftover disease after chemo
This trial tests ribociclib, a targeted therapy, for women with hormone receptor-positive, HER2-negative breast cancer who still have cancer cells in the breast or lymph nodes after initial chemotherapy. It aims to reduce the chance of cancer coming back.
Zhanjiang, GuangdongAges 18 years+ - NCT07405931Recruiting
Managing chemo side effects with phone calls and a smartphone app
This study tests whether checking in by phone or smartphone app can help manage chemotherapy side effects. If you are starting a new chemo for stomach, lung, breast, or colon cancer, this program may support you from home.
BusanAges 19 years+ - NCT07418125Recruiting
Study of tumor cell clusters in high-risk early breast cancer
This trial looks at whether clusters of tumor cells in the blood can give more information about high-risk early breast cancer. It is for people with certain types of breast cancer who are about to start treatment before surgery (neoadjuvant therapy).
LjubljanaAges 18 years+ - NCT07447414Recruiting
Freezing small hormone-driven breast cancers
This study tests cryoablation (freezing) to treat small, early stage breast cancers that are hormone receptor positive and HER2 negative. It may be an option for postmenopausal women who want to avoid surgery.
Lugo, LugoAges Any age - NCT07455188Recruiting
Switching targeted therapies for advanced HER2-positive breast cancer
This trial tests whether switching between two targeted therapy combinations can help women with HER2-positive advanced breast cancer that has progressed after previous treatments. It aims to find a new effective option for people who have already tried one or two lines of therapy.
Zhejiang, HangzhouAges 18 years+ - NCT07459673RecruitingPhase 2
HER2-positive breast cancer trial using ctDNA to guide treatment
This trial tests a personalized treatment plan for HER2-positive breast cancer that has spread. It uses a blood test to track cancer DNA and adjust therapy, including treatments that may help prevent cancer from reaching the brain. The goal is to achieve long-term remission.
Basking Ridge, New JerseyAges 18 years+ - NCT07478900Recruiting
Tattoo marking breast tumors before chemo
This trial tests a simple method: marking the tumor with a small tattoo before chemotherapy. The tattoo helps surgeons find the exact spot for lumpectomy after the tumor shrinks, so you can keep more of your breast.
Bhubaneswar, OdishaAges 18–75 - NCT07484087Recruiting
Ablation vs. Surgery for Early Breast Cancer
This trial compares a less invasive treatment called ablation (which uses extreme cold to destroy the tumor) with standard surgery for early-stage breast cancer. It is for women aged 50 or older with a small, low-risk tumor that has not spread.
Beijing, Beijing MunicipalityAges 50 years+ - NCT07492394RecruitingPhase 2
Testing dalpiciclib with or without entinostat and letrozole for early breast cancer
This trial is testing a combination of three drugs (dalpiciclib, entinostat, and letrozole) for women with early-stage, hormone-receptor-positive, HER2-negative breast cancer. It aims to see if adding these medications before surgery can help shrink the tumor.
Shijiazhuang, HebeiAges 18–75 - NCT07498829Recruiting
Cancer risk genetic testing for people with female organs
This study offers free genetic testing to women, trans men, and non-binary people (with female reproductive organs) who have not had previous testing for certain cancer-related genes. It aims to find people at higher risk for cancer so they can take steps to prevent it or catch it early.
LondonAges 18 years+ - NCT07507890Recruiting
Nipple-sparing mastectomy through one armpit incision
This trial tests a less invasive surgery for early-stage breast cancer that removes breast tissue through a single small cut in the armpit while keeping the nipple. It may be an option for women with small to medium breasts who are candidates for immediate breast reconstruction.
Candiolo, TurinAges 18 years+ - NCT07510698Recruiting
Same-day awake mastectomy with immediate breast reconstruction
This study tests whether people can have a mastectomy while awake (using numbing medicine instead of general anesthesia) and go home the same day with immediate breast reconstruction. It may be an option if you're healthy enough and have support at home.
Rome, RomeAges 18–75 - NCT07539038Recruiting
