Recruiting studies
- NCT07259226RecruitingPhase 2
Studying resistance to antibody-drug conjugates in advanced cancer
This study is for people with advanced breast, bladder, lung, or stomach cancer who are about to start treatment with a type of targeted therapy called an antibody-drug conjugate (ADC). The trial will collect tumor samples and blood to understand how cancers become resistant to these drugs and to find better ways to predict treatment success.
VillejuifAges 18 years+ - NCT06479239RecruitingPhase 1/Phase 2
Immune cell therapy for advanced pancreatic cancer
This trial tests a new immune cell therapy (EGFRBi armed PBMC) for people with advanced pancreatic cancer that can't be removed by surgery. It aims to see if this treatment can help control the cancer after you've already tried at least one type of chemotherapy and your disease is stable or better.

Study of A2B395 therapy for solid tumors with EGFR and HLA loss
This trial tests a new cell therapy called A2B395 for cancers that have EGFR, a protein on the cell surface, and have lost a specific marker called HLA-A*02. The therapy uses specially engineered immune cells to target and kill these cancer cells. This may help patients with colorectal, lung, head and neck, breast, kidney, or other solid tumors that are no longer responding to standard treatments.

Daphne, AlabamaAges 18 years+ - NCT04025164Recruiting
Shorter vs standard breast radiation after lumpectomy
This study compares a shorter course of radiation to a standard longer course after breast-conserving surgery (lumpectomy). It’s meant to see which schedule works just as well while focusing on safety and cancer control.

Study of BMS-986500 for advanced solid tumors
This trial tests a new drug called BMS-986500, alone or with other treatments, for people with advanced solid tumors that cannot be removed by surgery or have spread. It aims to see if the drug is safe and effective.
Birmingham, AlabamaAges 18 years+ - NCT06820255RecruitingPhase 4
DNA repair and platinum chemo for advanced bladder cancer
This trial tests how well platinum-based chemotherapy works in people with advanced bladder cancer that has certain DNA repair gene changes. It aims to see if these genetic markers can predict who benefits most from treatment.

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.
