Gastric (Stomach) Cancer clinical trials in California
We’re tracking 14 recruiting gastric (stomach) cancer studies with a site in California — including Phase 1, Phase 2, Phase 2/Phase 3 and Phase 3 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT04907643Recruiting
Virtual reality program to reduce stomach-cancer pain
This trial tests whether virtual reality (VR) can improve pain and other day-to-day symptoms in people with certain gastrointestinal cancers. You’d use VR for pain relief while researchers measure how you’re feeling.
Los Angeles, CaliforniaAges 18–99 - NCT05365581RecruitingPhase 1
Study drug for stomach and pancreatic cancers with lab-checked targets
This Phase 1 trial tests ASP2138 alone or with other cancer medicines in adults with stomach (including GEJ) or pancreatic cancer. You may be eligible if your tumor has a specific protein marker and your health tests and scan results meet safety requirements.
Orange, 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+ - NCT07059884Recruiting
Exercise program to help people with cancer stay active
This trial tests a distance-based exercise program designed to help people on chemotherapy maintain their physical function and prevent disability. It is for patients with certain cancers who are working full-time and can participate in moderate physical activity.
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+ - NCT07447050RecruitingPhase 2
Riluzole to Prevent Chemo-Related Cognitive Problems
This pilot study tests whether the drug riluzole can help prevent the thinking and memory problems (often called 'chemobrain') that some people experience during chemotherapy. If you are about to start a chemo regimen containing an anthracycline or platinum drug, you may be able to join.
Orange, CaliforniaAges 18 years+ - NCT06675136RecruitingPhase 1
Nab-paclitaxel PIPAC with paclitaxel and ramucirumab for stomach cancer spread to belly lining
This trial tests a new way to deliver chemotherapy directly into the belly for stomach cancer that has spread to the lining of the abdomen (peritoneal metastases). It also combines two standard chemotherapy drugs. The goal is to see if this approach can help people whose cancer progressed after first treatment.
Duarte, CaliforniaAges 18 years+ - NCT06203600RecruitingPhase 2/Phase 3
Nivolumab plus standard treatment for advanced stomach or esophageal cancer
This trial tests whether adding the immunotherapy drug nivolumab to standard treatment works better for advanced stomach or esophageal cancer. It is for people whose cancer has already progressed after a first round of chemo plus immunotherapy.
Anaheim, 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 - NCT05274048RecruitingPhase 1
Neratinib plus antibody-drug for HER2-positive stomach or esophagus cancer
This early-phase trial tests neratinib together with an antibody-drug to treat advanced HER2-positive gastro-esophageal (stomach/esophagus) cancer that can’t be removed by surgery. It’s for people whose cancer has progressed after at least one HER2-targeted treatment, aiming to shrink tumors and improve outcomes.
Palo Alto, CaliforniaAges 18 years+ - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Los Angeles, CaliforniaAges 18 years+ - NCT05677490RecruitingPhase 3
Chemo options, with or without nivolumab, for HER2-negative stomach cancer
This Phase 3 trial compares two standard chemotherapy regimens for advanced stomach, esophagus, or gastroesophageal junction cancer that is HER2-negative. It also tests whether adding nivolumab (an immune therapy) improves outcomes.
Antioch, CaliforniaAges 18 years+ - NCT06219941RecruitingPhase 2
Studying AZD0901 for Claudin18.2-positive advanced solid tumors
This trial tests a new drug called AZD0901 for people with advanced solid tumors that have a specific protein on their surface. It aims to see if the drug can shrink or slow the growth of these tumors.
Orange, CaliforniaAges 18 years+ - NCT04389632RecruitingPhase 1
Sigvotatug vedotin for advanced solid tumors that spread
This early-stage study tests a drug called sigvotatug vedotin in people with advanced solid cancers that cannot be removed or have spread. It aims to see how well the treatment works and what side effects it causes.
Los Alamitos, CaliforniaAges 18 years+

What taking part in a gastric (stomach) 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 gastric (stomach) cancer clinical trials in California?
- Yes. We're currently tracking 14 recruiting gastric (stomach) 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 gastric (stomach) 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 gastric (stomach) 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.
