Orange, CaliforniaAges 18 years+ - NCT05208762RecruitingPhase 1
PD-L1 antibody drug study for advanced lung and head/neck cancers
This Phase 1 trial tests a new experimental drug (PF-08046054/SGN-PDL1V) in people with advanced solid tumors that have not responded to standard treatment or can’t use it. It is designed to see how the drug works and how safe it is, with a focus on tumors that have PD-L1 seen on prior lab testing.
Irvine, CaliforniaAges 18 years+ - NCT03259867RecruitingPhase 2
TACE plus immune therapy for liver or stomach cancer
This trial tests a combination treatment using a targeted liver procedure plus an immune “checkpoint” medicine to slow cancer growth. It may help people with advanced liver cancer (HCC) or metastatic stomach cancer when standard treatments have not worked.
Orange, CaliforniaAges 18–80 - NCT07544589RecruitingPhase 1
Testing DISP-10 for Advanced Gastrointestinal Cancers
This early-stage trial tests a new experimental therapy called DISP-10 in patients with advanced cancers of the stomach, esophagus, or colon that have spread. The goal is to see if this treatment can help shrink tumors and how safe it is.
Duarte, CaliforniaAges 18 years+ - NCT07224750Recruiting
A blood test to find early signs of gastrointestinal cancer
This study is testing a blood-based test to detect unique molecules (called miRNAs) that may signal the presence of several types of gut or digestive system cancers. The goal is to develop a simple screening tool that could catch these cancers earlier.
Duarte, CaliforniaAges 18 years+ - 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+ - NCT07001748RecruitingPhase 2/Phase 3
Testing abdominal chemo plus standard chemo for stomach cancer spread
This trial tests adding the chemotherapy drug paclitaxel directly into the abdomen (intraperitoneal) along with standard IV chemotherapy for people with stomach or gastroesophageal junction cancer that has spread to the lining of the abdomen. The goal is to see if this combination helps control the cancer better than standard treatment alone.
Irvine, CaliforniaAges 18 years+ - NCT05702229RecruitingPhase 2
Study of combined medicines for advanced stomach cancer with Claudin18.2
This Phase 2 study tests new combination treatments for advanced stomach or stomach-esophagus junction cancer that cannot be removed by surgery. It may help people whose tumors are positive for a marker called Claudin18.2, which the study uses to choose who can receive the treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06324357RecruitingPhase 1/Phase 2
Zongertinib for HER2-positive cancers that have spread
This trial tests a new pill called zongertinib, alone or with other drugs, for people with HER2-positive cancers (like breast, stomach, or colorectal cancer) that have spread and are no longer responding to standard treatments. The goal is to find the best dose and see if it can help shrink tumors or slow the disease.
Cerritos, CaliforniaAges 18 years+ - NCT06605404Recruiting
Pan-tumor study of a blood test after cancer surgery
This study is testing a new blood test that looks for leftover cancer cells after surgery. It is for people with different types of solid tumors who are planning to have surgery to cure their cancer. The goal is to see if the test can help guide future treatment decisions.
San Diego, CaliforniaAges 18 years+ - NCT06427941RecruitingPhase 1
Study of BGB-B2033 drug for advanced solid tumors
This trial tests a new drug, BGB-B2033, alone or with other treatments, for people with advanced liver, stomach, lung, or germ cell cancers that have not responded to standard therapy. The goal is to see if the drug is safe and works against these tumors.
Duarte, CaliforniaAges 18 years+ - NCT06408220Recruiting
Stomach cancer risk check for minority groups
This study checks if you are at high risk for stomach cancer. You will give blood samples and have a stomach exam (endoscopy) to look for early signs.
Duarte, CaliforniaAges 40–80 - NCT07243015Recruiting
Detecting cancer spread risk with blood markers
This trial uses simple blood tests to find tiny bits of cancer that might remain after surgery for stomach cancer. It could help doctors predict if the cancer will come back or spread.
Duarte, CaliforniaAges 18 years+ - NCT07277413RecruitingPhase 1
Study of IDE892 for advanced solid tumors with MTAP deletion
This study tests a new drug called IDE892, alone or in combination, for people with advanced solid tumors that have a specific genetic change (MTAP deletion). The goal is to see if the drug is safe and whether it can shrink tumors.
Santa Rosa, CaliforniaAges 18 years+ - NCT07488676RecruitingPhase 1/Phase 2
Study of ASP546C for stomach, pancreas, and other cancers
This trial tests a new drug called ASP546C in people with certain advanced cancers that have a specific marker (CLDN18.2). It aims to see if the drug can shrink or slow tumor growth.
Los Angeles, CaliforniaAges 18 years+ - NCT04410302Recruiting
Personalized tumor research for bladder, lung, stomach, and liver cancers
This study uses a small sample of your tumor to grow it in the lab, which may help researchers understand your cancer better and find treatments that work for you.
Orange, CaliforniaAges 21–100 - NCT06995898Recruiting
Blood test study for early cancer detection
This study is testing a new blood test that may help find cancer early. You will give blood samples over a year, and researchers will check them for signs of cancer.
Pleasanton, CaliforniaAges 45–75 - NCT05482893RecruitingPhase 1/Phase 2
Spevatamig for advanced stomach, pancreas, or bile duct cancer
This trial tests a new drug called Spevatamig (PT886), alone or with different chemotherapy and/or immunotherapy combinations, for people with certain advanced stomach, pancreatic, or bile duct cancers. The goal is to see if it shrinks tumors and is safe.
Duarte, CaliforniaAges 18 years+ - NCT05059444Recruiting
Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.
Redwood City, CaliforniaAges 18 years+ - NCT06266299RecruitingPhase 1
Study of KK2269 for adults with solid tumors
This trial tests a new drug called KK2269 for adults with solid tumors that have spread or cannot be removed by surgery. It aims to see if the drug is safe and effective, possibly as a treatment option for certain cancers like lung or stomach cancer.

What taking part in a gastric 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.
