Recruiting studies in California
- 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+ - 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.

Duarte, CaliforniaAges 18 years+ - NCT04660760RecruitingPhase 2
Comparing two treatments for advanced stomach cancer after first treatment
This study tests two different treatment options for advanced stomach or gastroesophageal junction cancer that has grown after earlier chemotherapy. One option combines a targeted therapy (ramucirumab) with a chemotherapy pill (trifluridine/tipiracil), and the other is a standard chemotherapy drug (paclitaxel). The goal is to see which approach works better for people whose cancer has progressed, with the hope of improving outcomes.

Los Angeles, 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.

What taking part in a gastric / gastroesophageal junction 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.
