Recruiting studies in California
- NCT06172478RecruitingPhase 2
HER3-DXd for advanced solid tumors after prior treatment
This trial tests a new targeted drug called HER3-DXd for people with several types of advanced solid tumors that have stopped responding to standard treatments. The drug is an antibody-drug conjugate, designed to deliver chemotherapy directly to cancer cells that have a protein called HER3 on their surface.

Study of a new drug for advanced bladder and other solid tumors
This study tests a new drug (LY4052031) for people with several types of advanced solid tumors, especially bladder cancer. It aims to see if the drug is safe and effective when given alone or after other treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.

Study of PF-08046876 for advanced solid tumors
This trial tests a new medicine, PF-08046876, for people with advanced cancers of the bladder, lung, head and neck, esophagus, or pancreas. It aims to see if the drug is safe and works against these cancers.
Duarte, CaliforniaAges 18 years+ - NCT07124000Recruiting
T-DXd for advanced HER2-positive solid tumors
This trial is for people with advanced HER2-positive solid tumors (cancers that cannot be removed by surgery or have spread). It tests the drug T-DXd (also called Enhertu) when your doctor has already decided it's the right treatment for you and you have no other good options.

Testing NEO212 for brain tumors and metastases
This trial tests a new drug called NEO212 for people with certain brain tumors (like astrocytoma or glioblastoma) or cancer that has spread to the brain from other parts of the body. The goal is to see if it is safe and if it can help shrink or control the tumors.
Beverly Hills, CaliforniaAges 18 years+ - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors
This trial tests an experimental drug called BL-B01D1 for people with several types of advanced solid tumors, especially non-small cell lung cancer and breast cancer. It's designed for those whose cancer has continued to grow after standard treatments.
Orange, CaliforniaAges 18 years+ - NCT06242470RecruitingPhase 1
Study of MGC026 for advanced solid tumors
This trial tests a new drug called MGC026 that targets a protein called B7-H3 on cancer cells, aiming to shrink or slow different advanced solid tumors. It is an early-phase study to find the right dose and check safety.
Los Angeles, CaliforniaAges 18 years+ - NCT07059884Recruiting

Dublin, CaliforniaAges 18 years+ - NCT01048281Recruiting
Study of stomach and esophagus cancer samples
This study looks at stomach (gastric) and esophagus cancer, using clinical information and tissue samples. It may help researchers better understand these cancers and improve future care.
Stanford, CaliforniaAges 18 years+ - NCT07217704RecruitingPhase 3
New PET scan to find stomach or esophageal cancer spread
This trial tests a new PET scan drug (18F-FAPI) to see if it can better detect where stomach or esophageal cancer has spread. It may help doctors plan the right treatment for you.
Cerritos, CaliforniaAges 18 years+ - NCT07124351RecruitingPhase 4
Using a special dye to see cancer during surgery
This trial tests a drug called pafolacianine (CYTALUX) that makes cancer cells glow during surgery. It may help doctors see and remove more cancer from the stomach, esophagus, or appendix. You take the drug before surgery, and a special camera shows the glowing cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06298916RecruitingPhase 1/Phase 2
Study of 64Cu-LNTH-1363S in Sarcoma or GI Cancer
This trial tests a new imaging agent, 64Cu-LNTH-1363S, to see if it can find certain sarcomas and gastrointestinal cancers. The goal is to help doctors better see where your cancer is and plan the best treatment. You may be eligible if you have a sarcoma or a GI cancer and are willing to have a tumor tissue sample taken.
Orange, CaliforniaAges 15 years+ - NCT07227168RecruitingPhase 1
Study of STRO-004 for advanced solid tumors
This trial tests a new drug called STRO-004 for people with advanced solid tumors (cancers that have spread or come back). It aims to see if the drug is safe and effective for those who have already tried other treatments.
San Diego, CaliforniaAges 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.

San Francisco, CaliforniaAges 18 years+ - NCT05563766RecruitingPhase 2
Itraconazole added for treatable esophageal cancer before surgery

Santa Rosa, CaliforniaAges 18–80 - NCT07431281RecruitingPhase 3
New drug combo for advanced stomach cancer with CLDN18.2
This trial tests a new drug combination for people with advanced stomach cancer that has not been treated before. It looks at two groups: one with PD-L1 (a protein that helps decide if immunotherapy works), and one without. The treatment includes an antibody-drug conjugate (Sonesitatug Vedotin) plus standard chemotherapy, with or without an immunotherapy drug.
Walnut Creek, CaliforniaAges 18 years+ - NCT06203600RecruitingPhase 2/Phase 3

What taking part in a esophageal cancer study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there esophageal cancer clinical trials in California?
- Yes. We're currently tracking 51 recruiting esophageal cancer studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a esophageal cancer study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a esophageal cancer trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New esophageal cancer studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
