Recruiting studies
- NCT06454864Recruiting

Toronto, OntarioAges Any age - NCT04790253Recruiting
Check brain radiation timing or frequent MRI scans for SCLC
This study compares two ways to follow and treat small-cell lung cancer in the brain: preventive brain radiation versus close monitoring with MRI scans and treatment only if needed. It may help people avoid unnecessary brain treatment or choose the safer timing strategy.
GrazAges 18 years+ - NCT07017829RecruitingPhase 2
GT103 plus pembrolizumab for STK11 mutant lung cancer
This trial tests a new drug called GT103 combined with the immunotherapy pembrolizumab (Keytruda) for people with advanced lung cancer that has a specific genetic change (STK11 mutation) and has continued to grow despite prior pembrolizumab treatment. The goal is to see if adding GT103 can help shrink tumors or slow the cancer's growth.
Buffalo, New YorkAges 18 years+ - NCT06227338Recruiting
Testing a dye to see breast cancer during surgery
This trial uses a special dye called ICG that makes cancer glow under a special camera during breast cancer surgery. Doctors want to find the best time to give the dye so they can see the cancer clearly and remove all of it in one operation.
BrusselsAges 18 years+ - NCT04965064RecruitingPhase 2
Neratinib plus capecitabine for HER2-negative breast cancer brain mets
This study tests whether neratinib plus capecitabine can slow or shrink breast cancer that has spread to the brain. It is for people whose cancer shows an “overactive HER2 signal” on a specific tumor test, even though their cancer is labeled HER2-negative.
Rochester, New YorkAges 18 years+ - NCT06538896RecruitingPhase 2
Tislelizumab and nab-paclitaxel for advanced triple-negative breast cancer with bone spread
This trial tests a combination of two drugs, tislelizumab (an immunotherapy) and nab-paclitaxel (a chemotherapy), as the first treatment for advanced triple-negative breast cancer that has spread to the bones. It aims to see if this combination can help shrink or control the cancer.
Hangzhou, ZhejiangAges 18–70 - NCT05879926RecruitingPhase 3
Testing chemo after hormone therapy in premenopausal early breast cancer
This Phase 3 trial checks whether adding chemotherapy after standard hormone-blocking treatment works better for some premenopausal women with early-stage, ER-positive, HER2-negative breast cancer. It targets patients with limited lymph node spread and a lower-to-intermediate tumor “recurrence” risk score.
Birmingham, AlabamaAges 18–60 - NCT06595147Recruiting
Exercise for heart health in breast cancer survivors
This study tests if a 12-week exercise program improves heart health in women over 60 who have finished treatment for early-stage breast cancer. You will be placed in either an aerobic exercise group or a stretching group to see which helps your heart more.
Edmonton, AlbertaAges 60 years+ - NCT06878625RecruitingPhase 2
Trop-2 drug combo for advanced triple-negative breast cancer
This trial tests a new drug combination (Trop-2 antibody-drug conjugate plus other therapies) for advanced triple-negative breast cancer that has spread or come back. It may offer a new option for people who have had only 1–2 prior chemotherapies and have not used immunotherapy or anti-angiogenic drugs before.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT05247268RecruitingPhase 2
Hormone therapy to shrink early uterine cancer in young women
This trial tests whether combining two hormone medicines can treat early endometrial (uterine) cancer while helping preserve the uterus and future fertility. You may be eligible if your cancer is early and limited, with no spread seen on scans, and you can safely take these medicines.
ShanghaiAges 18–45 - NCT06966700RecruitingPhase 3
Study of Sac-TMT in Early High-Risk Breast Cancer
This study tests a new drug called Sacituzumab Tirumotecan (Sac-TMT) for people with early-stage, high-risk breast cancer that hasn't spread. The drug is given before surgery to see if it can shrink tumors and improve outcomes.
Gilbert, ArizonaAges 18 years+ - NCT06430541RecruitingPhase 1
Psilocybin therapy for fear of cancer recurrence
This trial tests if psilocybin-assisted therapy can help reduce the intense worry that cancer might come back. It is for people who have finished their main treatments for early-stage breast cancer or advanced ovarian cancer.
Aurora, ColoradoAges 21 years+ - NCT06224387RecruitingPhase 1/Phase 2
Study of a new drug for advanced solid tumors
This trial tests a new drug, CTS2190, for people with advanced solid tumors that have not responded to or cannot tolerate standard treatments. The goal is to see if the drug is safe and effective.
Luoyang, HenanAges 18 years+ - NCT06841354RecruitingPhase 3
Sac-TMT alone or with pembrolizumab for advanced triple-negative breast cancer
This trial tests a new drug, Sac-TMT, given alone or with an immunotherapy drug (pembrolizumab) for people with advanced triple-negative breast cancer who have not yet received any treatment for advanced disease. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Mobile, AlabamaAges 18 years+ - NCT04476485Recruiting
Predicting breast cancer recurrence after extended hormone therapy
This trial looks at factors that may predict whether hormone receptor–positive breast cancer will come back after you’ve already completed 5 years of hormone (endocrine) therapy. It may help identify who benefits most from longer treatment and follow-up.
Harbin, HeilongjiangAges 18–70 - NCT06789653Recruiting
Using age-related proteins in early breast cancer
This study is testing a new way to use proteins in your blood that change with age to better understand early-stage breast cancer. It may help doctors personalize your care.
Chapel Hill, North CarolinaAges 22–66 - NCT06393374RecruitingPhase 3
Study of a new drug combination for residual TNBC after initial treatment
This trial tests a new combination of two drugs (sacituzumab tirumotecan and pembrolizumab) compared to standard chemotherapy for people with triple-negative breast cancer that did not fully respond to initial treatment. It aims to see if this combination helps prevent cancer from coming back.
Mobile, AlabamaAges 18 years+ - NCT06169371RecruitingPhase 4
Abemaciclib dose escalation for early breast cancer
This study tests whether women with early-stage HR+/HER2- breast cancer can safely take a higher dose of the drug abemaciclib (Verzenio) after surgery. The goal is to keep the treatment as strong as possible while managing side effects.
Chicago, IllinoisAges 18 years+ - NCT05522959Recruiting
Exercise rehab for breast cancer recovery
This trial tests an exercise-based rehabilitation program for people who have had early-stage breast cancer and are finishing or currently getting standard treatments like chemotherapy, surgery, radiation, or targeted drugs. It may help improve heart and breathing fitness during recovery.
Toronto, OntarioAges 18 years+ - NCT05708235RecruitingPhase 2
Using blood test results to guide breast cancer treatment
This Phase 2 study tests whether doctors can use a blood test (ctDNA) to find breast cancer recurrence risk early and guide further treatment. Depending on your ctDNA result and tumor markers, you may receive standard hormone therapy or one of several additional treatment options.
A CoruñaAges 18 years+ - NCT06200168RecruitingPhase 3
Electroacupuncture to prevent nausea during breast cancer chemo
This study tests whether electroacupuncture can help prevent nausea and vomiting caused by strong chemotherapy in people with breast cancer. If you're starting a certain type of chemo, this could help you feel better during treatment.

Tucson, ArizonaAges 18 years+ - NCT06314906RecruitingPhase 3
Acupuncture plus anti-nausea drugs for breast cancer chemo side effects

Common questions
- Are there clinical trials for early-stage breast cancer?
- Yes. Clin2 currently lists 125 recruiting early-stage breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a early-stage breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a early-stage breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
