Recruiting studies
- NCT06103864RecruitingPhase 3
Study of Dato-DXd with or without durvalumab for advanced triple-negative breast cancer

This trial compares microsurgery to standard conservative therapy for long-lasting arm swelling caused by prior breast cancer. It may help people who still have swelling despite months of decongestive treatment by improving quality of life.
New Haven, ConnecticutAges 18 years+ - NCT05806060RecruitingPhase 3
Targeted first treatment for a rare TNBC subtype with spread
This Phase 3 trial tests a more precise treatment strategy for a specific rare type of triple-negative breast cancer (TNBC) called the BLIS subtype. It’s for people whose cancer has spread or cannot be fully removed and who have not had chemo or targeted therapy for metastatic TNBC yet.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05306041RecruitingPhase 2
Pre-surgery hormone therapy with or without PI3K inhibitor
This trial tests whether giving hormone-blocking treatment before surgery works better when combined with an added targeted drug for certain breast cancers. It may help shrink the tumor and improve outcomes for people whose tumors have specific hormone and genetic features.
Essen, North Rhine-WestphaliaAges 18 years+ - NCT05179889RecruitingPhase 2/Phase 3
Chemo after surgery for high-risk stage III colon cancer
This trial tests giving mFOLFIRINOX chemotherapy after curative surgery for people with high-risk stage III colon cancer. It aims to lower the chance that cancer comes back.
DaejeonAges 20–75 - NCT05007379Recruiting
Testing new immune cells on breast cancer samples in the lab
This trial studies whether newly made immune cells (“CAR-macrophages”) can attack breast cancer when tested on your tumor samples grown in the lab (“organoids”). If you need surgery or a tumor biopsy as part of your usual care, your sample may be used to test this approach.
LilleAges 18–100 - NCT07084519RecruitingPhase 3
Short vs standard radiation after mastectomy with implant reconstruction
This trial compares standard radiation therapy to a shorter course (hypofractionated) for women who have had a mastectomy with implant reconstruction. The goal is to see if the shorter schedule works as well while possibly reducing side effects for the reconstructed breast.
Beijing, ProvinceAges 18–75 - NCT06399419RecruitingPhase 1
Study of CBM588 with immunotherapy for advanced kidney cancer
This trial tests whether adding a probiotic (CBM588) to a standard immunotherapy combination (nivolumab and ipilimumab) helps treat advanced kidney cancer. It is for people with a specific type of kidney cancer that has spread or cannot be removed with surgery, who have not had systemic treatment before.
Duarte, CaliforniaAges 18 years+ - NCT07299812Recruiting
Protecting the heart during breast cancer radiation
This trial tests whether a special breathing technique (called Active Breathing Coordinator) can help keep radiation away from the heart while treating breast cancer with radiation therapy. If you can hold your breath briefly during treatment, this might lower the risk of heart damage.
Pavia, LombardyAges 18 years+ - NCT06726148RecruitingPhase 1/Phase 2
Study of ECI830 for advanced breast cancer and solid tumors
This trial is testing a new drug called ECI830, either alone or with another drug, for people with advanced breast cancer or other solid tumors that have not responded to standard treatments. It may be an option if you have HR+/HER2- breast cancer, small cell lung cancer, or a tumor with a specific gene change (CCNE1 amplification).
Los Angeles, CaliforniaAges 18–100 - NCT06358573RecruitingPhase 2
Injecting INT230-6 then immunochemo before surgery for early TNBC
This trial tests a two-step approach: first, an injection of the drug INT230-6 directly into the breast tumor, followed by a combination of immunotherapy and chemotherapy before surgery. The goal is to see if this sequence can shrink or eliminate the cancer more effectively, potentially allowing for a less extensive surgery.
LyonAges 18 years+ - NCT03572374Recruiting
Sharing breast cancer treatment plans with your workplace
This study tests tools to help people talk with employers and medical staff about breast cancer treatment while working. It aims to improve how treatment and job needs are discussed so patients can get support.
Basking Ridge, New JerseyAges 18–64 - 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+ - NCT04025541Recruiting
Blood tests to study tumor markers
This trial looks at blood samples to measure substances that may reflect cancer (tumor markers). It may help doctors understand cancer better and improve future monitoring, as long as you can safely and regularly take part.
MontpellierAges 18 years+ - NCT06127979Recruiting
Hormone therapy before surgery for breast cancer
This study looks at how a hormone-blocking medicine (endocrine therapy) given before surgery affects a marker called Ki67 in your breast cancer cells. The goal is to see if the medicine can slow the growth of the cancer, which may help doctors choose the best treatment for you.
New York, New YorkAges 18 years+ - NCT05704829RecruitingPhase 2
Trastuzumab-deruxtecan before surgery for HER2-positive early breast cancer
This trial compares giving trastuzumab-deruxtecan before surgery versus standard chemotherapy plus trastuzumab and pertuzumab. It aims to see which approach works better to shrink or control HER2-positive early breast cancer and improve outcomes.
Baden-Baden, Baden-WurttembergAges 18 years+ - NCT07085442Recruiting
Audit of targeted lymph node biopsy for early breast cancer
This study looks at how well a special type of lymph node biopsy works for people with early breast cancer that has spread to a small number of lymph nodes. It aims to see if this approach is effective and safe, which may help guide future treatment decisions.
BurnleyAges 18 years+ - NCT06830889RecruitingPhase 3
BL-M07D1 vs T-DM1 for HER2-positive breast cancer after neoadjuvant therapy
This trial tests whether a new drug called BL-M07D1 works better than an existing drug, T-DM1, for people with HER2-positive breast cancer who still have cancer cells after initial treatment (neoadjuvant therapy). The goal is to prevent the cancer from coming back.
Nanjing, JiangsuAges 18–75 - NCT05433753Recruiting
Study for leftover cancer DNA in HER2-positive early breast cancer
This study looks for tiny traces of cancer after treatment by testing blood for “ctDNA,” which is leftover cancer DNA. It includes people with HER2-positive early breast cancer who are getting chemotherapy before surgery to see if this blood test can detect signs of remaining disease.
Chuo-ku, TokyoAges 20 years+ - NCT07426952Recruiting

Durham, North CarolinaAges 18 years+ - NCT07832279Recruiting
Short versus long course radiation after breast-conserving surgery
This trial compares a one-week radiation treatment to a three-week treatment for early-stage breast cancer. It aims to see if the shorter course is as effective and safe, potentially making treatment more convenient.
ShanghaiAges 18–75 - NCT05559164RecruitingPhase 2
Statins to protect the heart during HER2 breast cancer treatment
This trial tests whether a cholesterol medicine (a statin) can lower the risk of heart damage in people receiving HER2-targeted breast cancer therapy. If you qualify, you may be given a statin and followed with heart tests and blood work to watch for safety and benefit.
Elizabeth, New JerseyAges 18 years+ - NCT06673329RecruitingPhase 1
Brodalumab for immune-related side effects from cancer treatment
This trial tests if brodalumab, an antibody that blocks a specific immune pathway (IL-17), can help control side effects caused by immunotherapy cancer treatment. It is for people with advanced solid organ cancers who have immune-related side effects that are suspected to involve IL-17.
New York, New YorkAges 18 years+ - NCT07376174Recruiting
HER2-positive breast cancer and dual-target therapy study
This study looks at how well a combination of two targeted drugs (trastuzumab and pertuzumab) works for people with HER2-positive breast cancer that hasn't spread. It aims to understand how HER2 levels affect treatment outcomes after surgery.
