Recruiting studies in California
- NCT06764316RecruitingPhase 1
Safety study of BAY 3547926 for advanced liver cancer
This trial tests a new drug called BAY 3547926 for people with advanced liver cancer that cannot be removed with surgery or has not responded to other treatments. The goal is to see if the drug is safe and how well it works.
Duarte, CaliforniaAges 18 years+ - NCT03257033RecruitingPhase 3
Gemcitabine through an artery versus by vein after radiation
This study tests whether giving gemcitabine directly into the artery feeding the pancreas (instead of through an IV) works better after you finish radiation therapy. It may help patients by improving how the medicine reaches the tumor while comparing side effects and outcomes between the two delivery methods.
Loma Linda, CaliforniaAges 18 years+ - NCT06885034RecruitingPhase 1/Phase 2
Testing a New Drug for Advanced Colon, Rectal, or Pancreatic Cancer
This study tests an experimental drug, alone or combined with other treatments, for advanced colon, rectal, or pancreatic cancer that hasn't responded to standard options or cannot be removed by surgery. The goal is to see if it is safe and if it helps shrink or slow the cancer.
Los Alamitos, CaliforniaAges 18 years+ - NCT04486833RecruitingPhase 1/Phase 2
Genetic-targeted drug plus gene medicine for EGFR lung cancer
This trial studies a gene-based treatment added to osimertinib (a targeted lung cancer pill) for advanced EGFR-mutant lung cancer that has started growing again on osimertinib. It may help by attacking the cancer with both its usual target treatment and an added genetic approach.
Los Angeles, CaliforniaAges 18 years+ - NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.

Testing new drugs, with or without pembrolizumab, for advanced esophageal cancer
This trial studies investigational cancer medicines, either alone or along with pembrolizumab, for people with advanced esophageal squamous cell cancer whose cancer has grown despite prior immune and platinum-based treatment. It may offer a new option after standard therapy has not worked.
Los Angeles, CaliforniaAges 18 years+ - NCT05410977Recruiting
Testing blood and stool for colon cancer in Lynch syndrome
This study collects blood and stool samples to see how well they can detect colorectal cancer or advanced growths in people with Lynch syndrome (an inherited colon cancer risk) or suspected Lynch syndrome. It may help find cancer or precancer earlier, which can improve next-step decisions.
San Francisco, CaliforniaAges 18 years+ - NCT06067295Recruiting
Long-term study of advanced prostate cancer
This study follows men with advanced prostate cancer that has spread to other parts of the body. It aims to learn more about how the disease and treatments affect patients over time, so doctors can improve care.
Los Angeles, CaliforniaAges 18 years+ - NCT06452277RecruitingPhase 3
Testing sevabertinib for advanced HER2-mutated lung cancer
This trial compares a new targeted drug called sevabertinib against standard chemotherapy plus immunotherapy for people with advanced non-small cell lung cancer that has a specific HER2 gene mutation. The goal is to see if sevabertinib works better and is safe.
Newport Beach, CaliforniaAges 18 years+ - NCT07444541RecruitingPhase 1/Phase 2
Study of ANO31905 plus chemo for CLDN18.2-positive pancreatic cancer

Duarte, CaliforniaAges 18 years+ - NCT04981509RecruitingPhase 2
Check if 3 medicines help advanced kidney cancer
This Phase 2 trial tests whether combining bevacizumab, erlotinib, and atezolizumab can shrink or control advanced kidney cancer. It’s aimed at people with certain kidney-cancer subtypes (including HLRCC-related cases or papillary kidney cancer) and who have not had many prior targeted or immune treatments.
La Jolla, CaliforniaAges 12 years+ - NCT04205968RecruitingPhase 2
Testing ramucirumab with chemo for advanced small bowel cancer
This trial studies whether adding ramucirumab to chemotherapy (either paclitaxel or FOLFIRI) works better for advanced small bowel adenocarcinoma that has already been treated with certain prior medicines. It may help shrink tumors or slow cancer growth in people whose cancer has progressed.

What taking part in a advanced 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 advanced cancer clinical trials in California?
- Yes. We're currently tracking 340 recruiting advanced 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 advanced 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 advanced 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 advanced 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.
