Recruiting studies
- NCT06293898RecruitingPhase 1
Study of BL-M07D1 for HER2-positive solid tumors
This trial tests a new drug, BL-M07D1, for people with advanced solid tumors that have a protein called HER2. It is for patients who have already tried at least two other standard treatments.
Birmingham, AlabamaAges 18 years+ - NCT06518382Recruiting
Study of leftover tumor after chemo and trastuzumab
This study looks at leftover breast cancer cells (after chemo and targeted therapy) to find out why some cells resist treatment. It may help doctors better understand how to treat HER2-positive breast cancer in the future.
Milan, LombardyAges 18 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT07808086Recruiting
Tumor bacteria in triple-negative breast cancer treatment response
This study looks at the bacteria found in the tumor to see if they affect how well chemotherapy or immunotherapy works in treating triple-negative breast cancer. The goal is to find ways to predict treatment response and improve care.
PaviaAges 18 years+ - NCT06508216RecruitingPhase 1/Phase 2
New drug combo for early relapsed triple-negative breast cancer
This trial tests experimental drugs for people with triple-negative breast cancer that came back within 12 months of finishing initial treatment. The goal is to see if these drugs are safe and can shrink or slow the cancer.
VillejuifAges 18 years+ - NCT06298084RecruitingPhase 1/Phase 2
HER3-DXd for Advanced Breast Cancer After T-DXd
This study tests a new drug called HER3-DXd (alone or combined with other medicines) for people with advanced breast cancer that has already been treated with T-DXd (Enhertu) and then got worse. The goal is to see if the new drug can shrink tumors safely.
Villejuif, FranceAges 18 years+ - NCT06943521RecruitingPhase 1/Phase 2
Study of MT-4561 for advanced solid tumors
This trial tests a new drug called MT-4561 in people with advanced solid tumors that have not responded to prior treatments. It aims to see if the drug can help shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06700070RecruitingEarly Phase 1
Testing a microdose drug in solid tumors before surgery
This study tests a tiny amount of an experimental drug (PBA-0111) injected directly into tumors that will be surgically removed later. The goal is to see how the drug affects the tumor tissue, which may help guide future treatments for solid tumors like head and neck cancer, certain sarcomas, or triple-negative breast cancer.
Shreveport, LouisianaAges 18 years+ - NCT04273061RecruitingPhase 2
Atezolizumab for tumors that look sensitive on DNA/RNA testing
This Phase 2 study tests atezolizumab, an immunotherapy drug, in people with advanced, incurable solid tumors whose tumor DNA/RNA suggests they may respond. The goal is to see if the treatment works better for patients selected by these lab results.
Vancouver, British ColumbiaAges 18 years+ - NCT05770531RecruitingPhase 2
Blood test guides chemo changes for metastatic breast cancer
This Phase 2 study uses a blood test that looks for “circulating tumor DNA” to help decide if standard chemotherapy should be changed. It aims to see whether this approach improves how well treatment works for certain metastatic (stage IV) breast cancers.
Nashville, TennesseeAges 18 years+ - NCT06508307RecruitingPhase 1
A study of an injected virus for advanced solid tumors
This trial tests a new treatment where a virus (GC001) is injected directly into a tumor. The virus is designed to attack cancer cells and may help people with advanced solid tumors that haven't responded to other treatments.
Zhengzhou, HenanAges 18–75 - NCT06265025RecruitingPhase 1/Phase 2
GM103 injection for advanced solid tumors that can't be removed
This trial tests an experimental drug called GM103 that is injected directly into tumors. It is for people with advanced solid tumors that have not responded to other treatments and cannot be surgically removed.
Goyang-si, Gyeonggi-doAges 18 years+ - NCT07646106RecruitingPhase 1
Testing THE-0504 in Advanced Solid Tumors
This Phase 1 trial tests a new drug called THE-0504 in patients with advanced solid tumors (like lung, colon, pancreas, stomach, or breast cancer) that have not responded to standard treatments. The study aims to find the right dose and understand how well and safely the drug works.
Rome, LazioAges 18 years+ - NCT05492682RecruitingPhase 1
First-in-human treatment for cancer using a drug injected into tumors
This Phase 1 trial tests PeptiCRAd-1, a treatment injected into a tumor, to see how safe it is and whether it can shrink cancers. It studies people whose cancer has come back or can’t be treated with standard options.
FrankfurtAges 18 years+ - NCT07261631RecruitingPhase 1
A study of a new radioactive drug for advanced solid tumors
This trial tests a new radioactive drug called [177Lu]Lu-DFC413 for people with certain advanced solid tumors that have stopped responding to standard treatments. The drug is designed to target cancer cells with a specific marker seen on a special scan.
Princeton, New JerseyAges 18 years+ - NCT05746325Recruiting
Tumor-pulse device for spinal cancer fluid spread
This trial tests whether Tumor Treating Fields (a non-surgical device that delivers treatment signals to cancer cells through the scalp/skin) can help people whose breast or lung cancer has spread into the fluid around the spine and brain. It focuses on people who have cancer cells found in spinal fluid and can safely use the device most of the day.
Jacksonville, FloridaAges 18 years+ - NCT06910657RecruitingPhase 1

Common questions
- Are there clinical trials for breast tumor?
- Yes. Clin2 currently lists 336 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.
