Recruiting studies
- NCT05634889Recruiting
Personalized breast radiation for limited lymph-node spread
This trial studies a tailored form of radiation treatment for some people with early breast cancer whose sentinel lymph-node biopsy shows cancer in 1–2 nodes. It may help improve local control while guiding the best radiation approach for your specific situation.
HelsinkiAges 18 years+ - NCT01042548Recruiting
Testing blood and tissue markers in breast surgery patients
This study looks at proteins and imaging patterns (from tissue, fluid near the tumor, and blood) to better understand breast cancer markers. It may help researchers find clues that doctors can use to evaluate breast nodules and newly diagnosed invasive breast cancer.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05603078Recruiting
Breast cancer surgery with a tumor-bed boost and standard radiation
This study looks at whether adding extra targeted radiation to the tumor area before breast-conserving surgery, then using modern breast surgery techniques and whole-breast radiation afterward, improves outcomes for early-stage breast cancer. You may be offered a treatment plan designed to better treat the area where the tumor was removed.
Beijing, Beijing MunicipalityAges Up to 55 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+ - NCT07352137Enrolling by invitation
Endoscopic Nipple-Sparing Mastectomy with Fat Grafting for Breast Reconstruction
This trial tests a new way to remove the breast through a small cut in the armpit (endoscopic nipple-sparing mastectomy) and immediately rebuild the breast using your own fat. It's for women with early-stage breast cancer who want to keep their nipple and have reconstruction at the same time.
Guanzhou, GuangdongAges 18–70 - NCT07253987Recruiting
Cancer Survivors Program for Breast or Prostate Cancer
This study offers a program to help people who have completed their main treatment for early-stage breast or prostate cancer. It focuses on follow-up and support during survivorship, and you are still eligible if you are on certain maintenance therapies like hormone therapy.
BrnoAges 18 years+ - NCT06422455Recruiting
Genetic testing for underserved cancer patients
This study offers free genetic testing to cancer patients and their healthcare providers. It aims to help people who may not have easy access to genetic testing understand their cancer risk.
Los Angeles, CaliforniaAges 18 years+ - NCT07109726RecruitingPhase 1/Phase 2
Testing TER-2013 for advanced tumors with AKT/PI3K/PTEN changes
This trial tests a new drug called TER-2013, alone or combined with another drug (fulvestrant), for people with advanced solid tumors that have specific genetic changes in the AKT/PI3K/PTEN pathway. It aims to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07876349Recruiting
Genetic testing program for breast and ovarian cancer risk
This study tests a program that helps primary care doctors identify women who may benefit from genetic testing for hereditary breast and ovarian cancer. The program uses family history to guide testing and aims to make it easier for patients to get tested.
New York, New YorkAges 21–75 - NCT04960839Recruiting
Preventive radiation to the other breast after breast cancer surgery
This study looks at whether “preventive” radiation to your other (opposite) breast can lower the chance of future breast cancer in people at higher genetic risk. You must have had surgery for early-stage breast cancer and agree to avoid removing the other breast and ovaries.
Jiangxi, JiangxiAges 30–70 - NCT07661641RecruitingPhase 1
Study of new radioactive treatments for GRPR-positive tumors
This early-phase study tests two new radioactive treatments (lutetium-177 and actinium-225) together with a guided imaging agent in people with GRPR-positive solid tumors (including prostate, breast, or colorectal cancers). The goal is to see if these treatments can shrink tumors that have stopped responding to standard therapies.
Melbourne N., VictoriaAges 18 years+ - NCT06534918Recruiting
Nutrition and exercise coaching for cancer survivors
This study tests whether personalized nutrition and exercise coaching helps cancer survivors improve their health after treatment. If you have had breast, prostate, colorectal, or lymphoma cancer and finished your main treatment at least 6 months ago, you may qualify.
Miami, FloridaAges 18 years+ - NCT06433349Recruiting
How cancer affects family health
This study looks at how cancer affects the whole family. If you or a loved one is being treated for certain cancers with the goal of a cure, researchers want to learn how to best support families during this time.
Odense CAges 18 years+ - NCT07390838RecruitingPhase 1
Study of SH009 for advanced solid tumors
This trial tests an investigational drug called SH009 for people with advanced solid tumors that have stopped responding to standard treatments. It aims to see if the drug is safe and effective.
ShanghaiAges 18 years+ - NCT07671937Recruiting
Sharing patient feedback in cancer care team meetings
This study gathers your feedback (like symptoms and quality of life) and shares it with your cancer care team during their group meetings, so they can better tailor your care. It is for people recently diagnosed with pancreatic, breast, or gynecologic cancer and aims to make sure your voice is heard in treatment decisions.
Birmingham, AlabamaAges 18 years+ - NCT05645510Recruiting
Study for people on long-term cancer targeted medicines
This study looks at people who are already taking long-term targeted cancer medicines. It may help researchers understand how these treatments work over time and whether there are ways to improve care.
Edmonton, AlbertaAges 18–90 - NCT07203729RecruitingPhase 2
A new drug for advanced breast cancer with severe symptoms
This trial tests a new drug called SHR-A1811 (a type of targeted therapy) for people with advanced breast cancer that is HER2-low and is causing severe symptoms (visceral crisis). The drug is given alone and aims to control the cancer and relieve symptoms.
Beijing, Beijing MunicipalityAges 18–75 - NCT07288359RecruitingPhase 1/Phase 2
Study of GVV858 for HR+/HER2- breast cancer and other solid tumors
This trial is testing a new drug, GVV858, either alone or with hormone therapy, for people with HR+/HER2- advanced breast cancer or certain other advanced solid tumors. It may be an option if standard treatments are no longer working or available.
Atlanta, GeorgiaAges 18 years+ - NCT06769425RecruitingPhase 1
Combination treatment for advanced solid tumors
This trial tests a new combination treatment for people with advanced solid tumors that have not responded to standard therapy. It aims to find a safe dose and see if the combination can shrink tumors.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06451497RecruitingPhase 1
Testing ZM008 alone and with toripalimab for advanced cancers
This trial tests a new drug called ZM008, which targets a protein on some cancer cells, first alone and then combined with another drug, toripalimab, for people with advanced solid tumors that have stopped responding to standard treatments.

This trial tests a new type of cell therapy (natural killer cells) made from a donor, combined with low-dose IL-15 (a protein that helps these cells work) and sometimes with pembrolizumab (Keytruda), for people with advanced solid tumors that have not responded to standard treatments. The goal is to see if this combination can shrink tumors or slow their growth.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 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.
