Recruiting studies in California
- NCT07343024Recruiting
Finding a Personalized Drug for Advanced Cancer
This trial looks at whether drugs not usually used for your type of cancer can help you. It matches your tumor's test results to possible treatments and works with your doctor to try one.
Palo Alto, CaliforniaAges Any age - NCT07306559RecruitingPhase 1
Testing a new drug for advanced solid tumors
This trial tests different doses of a new drug (BI 3820768) in people with advanced solid tumors, specifically germ cell tumors, endometrial cancer, or ovarian cancer. The goal is to see if the drug is safe and how well it works.
Los Angeles, CaliforniaAges 18 years+ - NCT07265674RecruitingPhase 3
Study of nanvuranlat for advanced bile duct cancer
This study tests a new drug called nanvuranlat for people with advanced bile duct cancer that has gotten worse after platinum-based chemotherapy. It compares nanvuranlat with the doctor's choice of standard treatments to see which works better.
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+ - NCT07223385RecruitingPhase 2
Heart health check for prostate cancer patients on ARPI therapy
This trial is for men with advanced prostate cancer who are taking ARPI therapy. It offers a special heart health consultation to help manage the increased heart risk that can come with these powerful cancer treatments.

San Francisco, CaliforniaAges 18 years+ - NCT07200830RecruitingPhase 3
Testing different schedules of a targeted radiation drug for advanced prostate cancer
This trial tests two different dosing schedules of a drug called Lutetium-177 PSMA RLT, which delivers radiation directly to prostate cancer cells.

Rina-S vs standard therapy for advanced endometrial cancer
This trial tests a new drug called Rina-S (an antibody-drug conjugate) against standard treatments for advanced endometrial cancer that has returned after prior therapy. It may be an option if you have had at least 1 but no more than 3 prior treatments, including platinum chemo and immunotherapy.
Irvine, CaliforniaAges 18 years+ - NCT07145177RecruitingPhase 1
Lu177-PSMA with liver treatment for advanced prostate cancer
This trial tests a targeted radiation drug (Lu177-PSMA) combined with procedures that treat liver tumors directly (like ablation or radiation). It is for men with prostate cancer that has spread to the liver and is no longer responding to hormone therapy. The goal is to see if this combination works better together.
San Francisco, CaliforniaAges 18 years+ - NCT07128680RecruitingPhase 1
Immunotherapy with or without a gut bacteria pill for kidney cancer
This trial tests whether adding a live bacteria pill (EXL01) to standard immunotherapy drugs (nivolumab and ipilimumab) helps treat advanced or metastatic kidney cancer that has clear cells. You may join if you have not had prior immunotherapy and your cancer has not been treated before (except possibly after surgery).
Irvine, CaliforniaAges 18 years+ - NCT07121972Recruiting
Validating AI for breast cancer risk prediction
This trial uses an AI model called Mirai to identify women at high risk for breast cancer based on their mammograms. If you are eligible, you may be invited for a breast MRI to better understand your risk.
San Diego, CaliforniaAges 40–89 - NCT07111507RecruitingPhase 2
Tarlatamab for advanced prostate cancer
This trial tests a drug called tarlatamab for people with advanced prostate cancer that has a specific protein (DLL3) on their tumor cells. The goal is to see if tarlatamab can help shrink or slow the cancer.
San Diego, CaliforniaAges 18 years+ - NCT07097142RecruitingPhase 3
Shorter radiation for bladder cancer with chemo
This trial tests if a shorter course of radiation therapy works as well as the usual longer course for people with bladder cancer who are also receiving standard chemotherapy. The goal is to see if shorter treatment can reduce side effects while still being effective.
Orange, CaliforniaAges 18 years+ - NCT07102381RecruitingPhase 2
Zanidatamab plus chemo before surgery for HER2+ breast cancer
This trial tests a new drug called zanidatamab combined with chemotherapy to shrink HER2-positive breast cancer before surgery. It may help improve treatment outcomes for people with stage 2 or 3 breast cancer that has not spread.
Long Beach, CaliforniaAges 18 years+ - NCT07077239Recruiting
Adaptive radiation after prostate surgery to lower side effects
This trial tests a precise, short-course radiation treatment (stereotactic body radiotherapy) after prostate removal surgery that adapts to your body each day to reduce side effects. It is for people whose prostate cancer has high-risk features or a rising PSA after surgery.

Study of MRG007 for advanced solid tumors
This trial tests a new drug called MRG007 for people with advanced solid tumors that haven't responded to other treatments. The drug targets a protein called CDH17 on cancer cells; you need a tumor sample to check for it.
Los Angeles, CaliforniaAges 18 years+ - NCT07070466RecruitingPhase 2
Ivonescimab with chemotherapy for advanced stomach or esophageal cancer
This study tests a new drug called ivonescimab combined with standard chemotherapy (FOLFOX) for people with advanced adenocarcinoma of the esophagus, stomach, or gastroesophageal junction. The drug is designed to help the immune system fight cancer. The study is for people who have not had prior treatment for stage IV disease and whose cancer is HER2 negative.

What taking part in a 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 cancer clinical trials in California?
- Yes. We're currently tracking 1,320 recruiting 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 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 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 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.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
