Recruiting studies
- NCT06984250Recruiting
Shorter radiation with extra focus on tumor site for breast cancer
This trial tests a shorter course of radiation therapy that includes an extra dose to the tumor site for women with early-stage breast cancer. It aims to make treatment more convenient and effective after breast-conserving surgery.
Taipei, TaiwanAges 20–85 - NCT03971045RecruitingPhase 2
Pembrolizumab plus low-dose oral chemo for chest wall breast cancer
This Phase 2 trial tests pembrolizumab (an immune therapy) plus low-dose oral cyclophosphamide in people with chest wall breast cancer that has spread locally and may have distant metastases. It aims to see if this combination can shrink tumors and control cancer longer, especially in tumors with certain immune markers.
MilanAges 18 years+ - NCT05544240RecruitingPhase 1
First-in-human immunotherapy study for advanced solid tumors
This Phase 1 trial tests SYNC-T, an immunotherapy, in people with advanced or metastatic solid cancers. It aims to find the safest dose and see whether the treatment can shrink or control tumors.
Mexico CityAges 18 years+ - NCT07218432Recruiting
TheraBionic device study for hormone-positive breast cancer
This trial tests a device called TheraBionic P1, which uses low-level radiofrequency energy, for women with early-stage hormone receptor-positive, HER2-negative breast cancer. It is given before surgery to see if it can help shrink the tumor.

Study of ETX-19477 for advanced solid tumors
This trial tests an experimental drug called ETX-19477 for people with advanced solid tumors that have stopped responding to other treatments. It aims to see if the drug is safe and effective, especially for those with certain genetic changes (BRCA2 mutations).
Phoenix, ArizonaAges 18 years+ - NCT07552467Recruiting
PET Imaging Scan for Detecting Cancer Using New Radioactive Tracer
This study tests a new type of imaging scan (PET/CT or PET/MR) that uses a radioactive tracer to help doctors better detect and diagnose various cancers. The scan targets a specific protein found in tumors, which may help identify cancer more accurately than standard imaging.
Wuhan, HubeiAges 18 years+ - NCT07274852RecruitingPhase 1
Study of a radioactive drug for advanced solid tumors
This trial tests a new radioactive drug (177Lu-BL-ARC001) for people with advanced lung, breast, head and neck, or other solid tumors that have not responded to standard treatments. It aims to see if the drug can target and shrink tumors while limiting side effects.
Chengdu, SichuanAges 18 years+ - NCT07660055RecruitingPhase 1
Radioactive drug for advanced solid tumors
This trial tests a new radioactive drug (called 177Lu-DWJ155) that targets and kills cancer cells, along with a similar imaging agent (68Ga-DWJ155) used to see where the drug goes in the body. It is for people with certain advanced solid tumors that have not responded to standard therapies.
Omaha, NebraskaAges 18 years+ - NCT07331532Recruiting
New pet scan to detect annexin a2 in lung tumors
This trial tests a new injection called 68Ga-PFA2 for PET/CT scans to find a protein called Annexin A2 in lung cancer tumors. It aims to see if this scan can better detect or characterize these tumors in patients who will have a biopsy or surgery soon.
Beijing, Beijing MunicipalityAges 18–80 - NCT07741435Recruiting
Simple blood, urine, and saliva test to find cancer early
This study tests a new way to find cancer by looking at DNA in blood, urine, and saliva. It may help detect cancer earlier and monitor how well treatment works.
Bogotá, Bogota D.C.Ages 18 years+ - NCT03392233RecruitingPhase 2
Targeted radiation for spinal metastases causing significant pain
This trial tests a focused form of radiation (stereotactic body radiation) to treat cancer spread to the spine, especially when it causes substantial pain. It may help shrink or control the spinal spots while limiting damage to surrounding tissues.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT04741737Recruiting
Repeat lymph node biopsy for recurrent breast cancer
This study tests whether repeating a specific lymph node biopsy (sentinel lymph node biopsy) is safe and useful in people whose breast cancer has come back in the same breast. It may help doctors better understand whether lymph nodes are involved and guide next steps after surgery.
SeoulAges 19 years+ - NCT06572410Recruiting
SmartClip and navigation system during lumpectomy
This study tests a new navigation system used during breast-conserving surgery (lumpectomy). It helps the surgeon locate and remove tumors more precisely using a tiny marker placed beforehand.
Winter Garden, FloridaAges 18 years+ - NCT06695845RecruitingPhase 2
Study of zanidatamab for HER2-positive solid tumors
This trial tests a drug called zanidatamab in people with advanced solid tumors that have high levels of HER2 protein (called HER2-positive). It aims to see if zanidatamab can shrink or slow the growth of these tumors.
Prescott, ArizonaAges 18 years+ - NCT06905561Recruiting
Diclofenac cream to prevent skin irritation from radiation
This trial tests if a diclofenac cream can help prevent skin redness, peeling, or pain caused by radiation therapy. It is for people with certain head and neck cancers or breast cancer who are starting radiation treatment.
Haikou, HainanAges 18–75 - NCT07023848Enrolling by invitationEarly Phase 1
Imaging study for HER2-positive cancers using a special tracer
This study uses a radioactive tracer to take pictures of tumors that have a protein called HER2. It may help doctors see where the cancer is in your body and could guide future treatment decisions.
Wuxi, JiangsuAges 18–75 - NCT06998407RecruitingPhase 1/Phase 2
Study of AVZO-023 for advanced solid tumors
This trial tests a new drug, AVZO-023, alone or with other treatments, for people with advanced solid tumors that have not responded to standard therapy. The goal is to see if it can shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT05000294RecruitingPhase 1/Phase 2
Atezolizumab plus tivozanib for hard-to-treat “cold” cancers
This early-stage study tests whether combining atezolizumab and tivozanib can shrink advanced, hard-to-treat cancers that do not strongly activate the immune system (“immunologically cold”). It is for people whose cancer has already been treated or has no good standard options.
Gainesville, FloridaAges 18–99 - NCT04842812RecruitingPhase 1
Personalized immune cell therapy for advanced solid tumors
This Phase 1 study tests engineered immune cells (TILs/CAR-TILs) made from your tumor to treat advanced solid cancers that have not responded to standard treatments. It may help your immune system better recognize and attack the cancer, but it is mainly focused on safety and early results.
GuangzhouAges 18–85 - NCT06479460Recruiting
Blood test monitoring during chemo before surgery for HER2-positive breast cancer
This trial tests whether a blood test (ctDNA) can help doctors monitor how well chemotherapy before surgery is working in women with HER2-positive breast cancer. It aims to see if changes in the blood can predict treatment success.
Nanjing, JiangsuAges 18–75 - NCT04997993RecruitingPhase 1
Leflunomide for PTEN-altered or HER2-negative metastatic cancers
This Phase 1 trial studies whether leflunomide can slow or control advanced (metastatic) cancers in people whose tumors have specific PTEN changes or who have HER2-negative breast cancer. It’s primarily a safety-and-dosing study, but it may offer benefit if your cancer matches the tumor marker requirements.

Common questions
- Are there clinical trials for breast tumor?
- Yes. Clin2 currently lists 340 recruiting breast tumor 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 tumor 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 tumor 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.
