Recruiting studies
- NCT01174121RecruitingPhase 2
Immunotherapy made from your tumor-fighting immune cells
This trial tests a treatment made from your own immune cells (called tumor-infiltrating lymphocytes, or TILs) for certain metastatic cancers. It’s designed for people whose cancer has not responded to standard treatments and who can safely provide a small tumor sample for cell-making.
Bethesda, MarylandAges 18–72 - NCT07381985Enrolling by invitation

Compare two breast surgery skin-sparing methods and recovery
This trial compares two types of mastectomy (with skin and nipple options) and implant reconstruction to see which gives better cosmetic results, comfort, and satisfaction. You may help doctors learn which approach leads to a better quality of life after surgery.
BudapestAges 18–65 - NCT06731894RecruitingPhase 2
Cannabis for nerve pain after chemotherapy in breast and colon cancer survivors
This trial tests whether a cannabis-based product can reduce nerve damage (neuropathy) caused by chemotherapy in people who have finished treatment for breast or colon cancer. It focuses on survivors who still have pain, numbness, or tingling in their hands or feet.
Duarte, CaliforniaAges 18 years+ - NCT06500481RecruitingPhase 3
Proton vs standard radiation for cancer spread to brain/spine lining
This trial compares a newer type of radiation (proton therapy) to standard radiation for people whose breast or lung cancer has spread to the lining of the brain and spinal cord. It aims to see if proton therapy can better control the disease while causing fewer side effects.
Phoenix, ArizonaAges 18 years+ - NCT07358806RecruitingPhase 1
Study of OCT-598 for advanced solid tumors
This trial tests a new drug called OCT-598, alone or with chemotherapy, for people with advanced solid tumors that have not responded to other treatments. It aims to see if the combination is safe and effective.
Goyang-siAges 18 years+ - NCT07060807RecruitingPhase 3
Study of Patritumab Deruxtecan for Advanced HR+/HER2- Breast Cancer
This trial tests a new drug called patritumab deruxtecan (a targeted therapy) for people with a common type of advanced breast cancer (HR+/HER2-). It's for those whose cancer has grown despite treatment with a CDK4/6 inhibitor plus hormone therapy.
Daphne, AlabamaAges 18 years+ - NCT07737951Recruiting
Tai chi for joint pain from breast cancer hormone therapy
This trial tests whether tai chi can help reduce joint pain caused by aromatase inhibitors, which are hormone therapies for breast cancer. If you have joint pain from this treatment, tai chi might be a gentle way to find relief.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07423039Recruiting
Ear acupressure for anxiety and pain during breast cancer surgery
This study tests if pressing on specific points on the ear (acupressure) can help reduce anxiety and pain during breast cancer surgery. It compares acupressure plus standard care to standard care alone, and may be a drug-free way to help you feel calmer before and after your procedure.
StuttgartAges 18–99 - NCT05071105Recruiting
Short-course radiation for early breast cancer in older women
This study looks at a brief type of radiation called SBRT given soon after starting hormone therapy for certain early breast cancers in women age 75 and older. It may help treat the cancer locally while aiming to be easier to receive than longer radiation schedules.
Rome, RomeAges 75 years+ - NCT07591857Recruiting
Computer-Based Brain Training for Cancer-Related Memory Loss
This study tests whether a computer-based brain training program delivered in a group setting can help women who experienced memory or thinking problems after breast cancer treatment. The program is designed to retrain and improve how your brain processes information.
JerusalemAges 18 years+ - NCT06629233Enrolling by invitation
New immunotherapy targets for estrogen-receptor positive breast cancer
This trial tests a new technique to find unique targets on breast cancer cells that could be used for future immunotherapies. It focuses on women with estrogen-receptor positive primary breast cancer.
Ghent, East-FlandersAges 18 years+ - NCT07711847Recruiting
Prone positioning for faster breast radiation therapy
This trial tests a personalized prone-immobilization device for partial breast radiation after surgery. It aims to make treatment more comfortable and accurate for patients who have had breast-conserving surgery.
New York, New YorkAges 40 years+ - NCT07258563Recruiting
Can a special diet prevent taste changes from chemo?
This study looks at whether a special diet can help prevent taste changes during chemotherapy. It is for people with certain cancers who are about to start treatment.
AmsterdamAges 18–70 - NCT03975179Recruiting
Frozen biopsy vs no frozen biopsy during breast-conserving surgery
This study compares two approaches during breast-conserving surgery: doing a quick “frozen section” biopsy during the operation versus deciding later without it. It aims to see which approach better guides treatment decisions about whether the cancer is close to the removed tissue edges (margins).
Goyang-siAges 19–70 - 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 - NCT05300464Recruiting
Test MammoWave for finding breast lesions on imaging
This study checks how well MammoWave can help detect breast lesions (areas that may be abnormal) using imaging. It may help doctors confirm findings by combining it with other scans when needed, and sometimes with biopsy results.
Genova, GenovaAges 18 years+ - NCT05440227RecruitingPhase 2
PG2 shots to reduce moderate to severe breast cancer fatigue
This Phase 2 trial tests whether PG2 injections can safely reduce moderate to severe fatigue in people receiving chemotherapy for locally advanced, recurrent, or metastatic breast cancer. If you qualify, you may be asked to complete questionnaires and follow study plans for about 8 weeks.
TaipeiAges 20 years+ - 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+ - NCT06312176RecruitingPhase 3
Study of new drugs for HR+/HER2- advanced breast cancer
This trial tests two new drugs (sacituzumab tirumotecan and pembrolizumab) against standard treatments for a type of advanced breast cancer that is hormone receptor positive and HER2 negative. It's for people whose cancer has worsened despite hormone therapy with a CDK4/6 inhibitor.
Chandler, ArizonaAges 18 years+ - NCT06318507Recruiting
Gut Bacteria and Immunotherapy for Triple-Negative Breast Cancer
This study looks at how bacteria in your gut might affect the way your body responds to immunotherapy for triple-negative breast cancer. It focuses on women who are overweight or obese and are about to start treatment with pembrolizumab before surgery.
Baton Rouge, LouisianaAges 18 years+ - NCT05585788Recruiting
Opioid pain device test for cancer surgery patients
This study tests a device that helps you safely use opioid (strong pain) medicine after major cancer surgery. It may help improve post-surgery pain control while tracking how people use the medicine.
New York, New YorkAges 18–99 - NCT06369831RecruitingPhase 2
Imaging test for HER2 in metastatic cancer
This trial uses a special imaging scan to see if your cancer has HER2 on its surface, which could help decide if HER2-targeted treatment might work for you. It's for people with metastatic breast cancer or other solid tumors that have spread.
Innsbruck, TyrolAges 18 years+ - NCT06725082RecruitingPhase 1

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,469 recruiting 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 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 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.
