Recruiting studies
- NCT07648914RecruitingPhase 3
BL-B01D1 versus chemotherapy for advanced hormone-receptor-positive breast cancer
This trial tests a new targeted drug called BL-B01D1 against standard chemotherapy in patients with advanced breast cancer that is hormone-receptor-positive (HR+) and HER2-negative, and has stopped responding to hormone treatments. The goal is to see if the new drug works better or has fewer side effects.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06889610RecruitingPhase 2
Ablation plus drug therapy for advanced solid tumors
This trial tests combining a liver tumor ablation procedure with systemic drugs for people with advanced colorectal, breast, or melanoma cancer that has spread to the liver. The goal is to see if this approach can help when standard treatments have stopped working.
ShanghaiAges 18–80 - NCT06240195Recruiting
Study of sacituzumab govitecan for advanced triple-negative breast cancer
This study is testing a drug called sacituzumab govitecan (SG) for people with advanced triple-negative breast cancer who have already had other treatments. The goal is to see how well the drug works and what side effects it causes, using your tumor samples to look for clues (biomarkers).
Rome, RomeAges 18 years+ - NCT04892693RecruitingPhase 2
Talazoparib for advanced breast cancer with DNA repair defects
This trial studies talazoparib (a targeted pill) in people with advanced breast cancer whose tumors have problems repairing certain DNA damage. If your tumor has these specific “DNA repair” defects, the medicine may work better and stop the cancer from growing.
SeoulAges 19 years+ - NCT06551220Recruiting
T-DXd for advanced breast cancer with various HER2 levels
This study looks at how well the drug T-DXd (Enhertu) works against breast cancer that has spread or can't be removed with surgery. It includes patients with any level of HER2 protein, so it might be an option even if your cancer has low HER2.
New Haven, ConnecticutAges 18–80 - NCT05746897RecruitingPhase 1
First-in-human test of an anti-PVRIG drug for advanced cancers
This early-phase study tests NM1F (an anti-PVRIG antibody) in people with advanced solid tumors to see if it’s safe and whether it may work. It also includes pembrolizumab (a PD-1 “checkpoint” medicine), aiming to boost the immune system against the cancer.
Dallas, TexasAges 18 years+ - NCT05076760RecruitingPhase 1
Study of a cancer-killing virus with standard treatments
This Phase 1 trial tests MEM-288, an oncolytic (cancer-killing) virus, either alone or combined with standard cancer medicines, in people with advanced solid tumors. It’s designed to see how the treatment works and how safe it is in different cancer types and after specific prior therapies.
Tampa, FloridaAges 18 years+ - NCT06837792RecruitingPhase 2
T-DXd vs hormone therapy for HER2-low advanced breast cancer
This trial compares a targeted antibody-drug conjugate called T-DXd against standard hormone therapy for women with HR+, HER2-low advanced breast cancer that has progressed after first-line endocrine therapy plus a CDK4/6 inhibitor. It aims to see if T-DXd works better than continuing hormone therapy alone.
SeoulAges 19 years+ - NCT06793332RecruitingPhase 2
Ivonescimab and Trodelvy for breast cancer with brain metastases
This trial tests two drugs (Ivonescimab and a Trop2 ADC) for people with triple-negative breast cancer that has spread to the brain. It aims to see if this combination can shrink brain tumors and help patients live longer.
Shanghai, Shanghai MunicipalityAges 18–70 - 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.
Orlando, FloridaAges 18 years+ - NCT07203729RecruitingPhase 2
Trastuzumab rezetecan for her2-low breast cancer with visceral crisis
This trial tests a new antibody-drug combination called trastuzumab rezetecan (SHR-A1811) in people with a specific type of breast cancer (HER2-low) that has spread and is causing serious organ problems (visceral crisis). The goal is to see if this treatment can help when organs like the liver or lungs are rapidly failing due to the cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06846437RecruitingPhase 3
New drug JSKN003 vs. Kadcyla for HER2-positive advanced breast cancer
This trial compares a new targeted therapy (JSKN003) against Kadcyla (T-DM1) for people with HER2-positive breast cancer that has advanced or spread. Both drugs work by attaching a chemotherapy directly to HER2-positive cancer cells, and the study aims to see if the new drug works better or has fewer side effects.
ShanghaiAges 18 years+ - NCT05668962RecruitingPhase 2
Study selpercatinib plus I-131 for RET thyroid cancer that cannot take iodine
This trial tests whether combining a targeted pill (selpercatinib) with a radioactive iodine dose (I-131) can shrink thyroid cancer that has spread and no longer responds to radioactive iodine. It is for RET fusion–positive (genetically driven) thyroid cancers where the cancer cannot reliably absorb iodine anymore.
Washington D.C., District of ColumbiaAges 12 years+ - NCT05111561RecruitingPhase 1
Testing a two-drug combo for RAS-mutant or triple negative breast cancer
This study tests a combination of two new drugs, ZEN003694 and binimetinib, for people with advanced solid tumors that have certain gene changes (like RAS mutations) or triple negative breast cancer. The goal is to see if this combination can shrink tumors or slow their growth.
Boston, MassachusettsAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.

Common questions
- Are there clinical trials for unresectable breast cancer?
- Yes. Clin2 currently lists 272 recruiting unresectable 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 unresectable 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 unresectable 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.
