Recruiting studies in California
- NCT06038578RecruitingPhase 2
TRK-950 with standard chemo for advanced stomach cancer
This trial tests a new drug, TRK-950, added to standard chemotherapy (ramucirumab and paclitaxel) for people with advanced stomach or gastroesophageal junction cancer that has worsened after previous treatment. The goal is to see if this combination can help shrink tumors or slow disease progression.

Pumitamig vs Nivolumab for untreated stomach or esophagus cancer
This trial compares two treatments for people with advanced stomach, gastroesophageal junction, or esophageal cancer that has not been treated before. One group gets pumitamig plus chemotherapy, the other gets nivolumab plus chemotherapy. The goal is to see which combination works better.
Los Angeles, CaliforniaAges 18 years+ - NCT05482893RecruitingPhase 1/Phase 2
Study of spevatamig for advanced gastrointestinal cancers
This trial tests a new drug called spevatamig (PT886) alone or with other treatments for advanced stomach, gastric, pancreatic, bile duct, or colorectal cancers. The goal is to see if it helps slow or stop cancer growth.
Duarte, CaliforniaAges 18 years+ - NCT05733689RecruitingPhase 1
Testing new pre-surgery treatment for stomach and esophagus cancer
This Phase 1 trial tests how well a tailored (response-adapted) chemotherapy plan works before surgery for stomach or gastroesophageal junction cancer. It aims to improve treatment planning while checking early safety.
Orange, CaliforniaAges 18 years+ - NCT07090499RecruitingPhase 1
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+ - NCT05059444Recruiting
Blood test to catch cancer early after treatment
This study looks for signs of cancer left in the body after treatment using a simple blood test (called a liquid biopsy). It aims to see if the test can catch cancer that might come back earlier than regular scans.
Sacramento, CaliforniaAges 18 years+ - NCT06764875RecruitingPhase 3
New drug combo for HER2-positive stomach cancer
This trial tests a new immunotherapy called rilvegostomig combined with standard chemotherapy and a targeted therapy (trastuzumab deruxtecan) for people with advanced HER2-positive stomach or gastroesophageal junction cancer that has not been treated before.
Duarte, CaliforniaAges 18 years+ - NCT04510129Recruiting
Cancer biospecimen collection study for immunotherapy patients
This study collects samples (like tissue biopsies and imaging information) from people with certain cancers who are starting anti–PD-1/PD-L1 immunotherapy. It helps researchers gather material to study how these treatments work.
San Francisco, CaliforniaAges 18 years+ - NCT03175224RecruitingPhase 2
Test drug APL-101 for lung or other tumors with MET changes
This Phase 2 study tests APL-101 to shrink advanced cancers that have certain MET-related changes, including specific MET mutations, MET gene amplification, or MET fusions. It may help people whose tumors have run out of standard treatment options.
Los Angeles, CaliforniaAges 18 years+ - NCT06047379RecruitingPhase 1/Phase 2
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+ - 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+ - 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.
Arroyo Grande, CaliforniaAges 40–75 - NCT04900818RecruitingPhase 1
Givastomig for advanced solid cancers, including gastric and pancreas
This Phase 1 trial tests how safe and effective givastomig (TJ033721) is for advanced or metastatic solid tumors. It may help people whose cancer has grown despite standard treatment, or—if in the combination parts—specific cancers that meet certain lab test and tumor-marker requirements.
Orange, CaliforniaAges 18 years+ - NCT07218003Enrolling by invitationPhase 1
Study of RNDO-564 alone or with pembrolizumab for bladder cancer
This trial tests an experimental drug, RNDO-564, either by itself or combined with another drug (pembrolizumab), for people with advanced bladder cancer or other solid tumors that have stopped responding to standard treatments. The goal is to see if it can shrink tumors or slow cancer growth.
San Francisco, 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.
Glendale, CaliforniaAges 18 years+ - NCT07432295RecruitingPhase 2
Givastomig plus nivolumab and chemo for advanced stomach cancer
This trial tests a new drug, givastomig, combined with standard immunotherapy (nivolumab) and chemotherapy for people with advanced stomach, gastroesophageal junction, or esophageal cancer. It is for people whose tumors have certain markers (CLDN18.2 and PD-L1) and who have not had treatment for advanced disease.
Duarte, CaliforniaAges 18 years+ - NCT05563766RecruitingPhase 2
Itraconazole with standard treatment for esophageal cancer
This trial tests whether adding the antifungal drug itraconazole to the usual chemotherapy and radiation before surgery can improve the chance of no cancer cells remaining at surgery. It is for patients with esophageal or gastroesophageal junction cancer that can be surgically removed.
Palo Alto, 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.
Palo Alto, 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+ - NCT05086692RecruitingPhase 1/Phase 2
Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.

What taking part in a gastroesophageal adenocarcinoma 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.

- 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 gastroesophageal adenocarcinoma 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.
