Recruiting studies in California
- NCT07054346RecruitingPhase 1
Radioactive drugs before prostate surgery for high-risk prostate cancer
This trial compares two radioactive drugs (177Lu-PSMA-617 and 225Ac-PSMA-617) given before prostate removal surgery in men with high-risk prostate cancer that has not spread far. The goal is to see which drug is better at shrinking the tumor and reducing the chance of cancer coming back.
San Francisco, CaliforniaAges 18 years+ - NCT07029399RecruitingPhase 1
Study of NKT5097 for advanced solid tumors
This trial tests an experimental oral drug (NKT5097) for people with advanced solid tumors that have not responded to other treatments. It may also be an option for people with a specific type of breast cancer (HR+/HER2-). The goal is to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT07030686Recruiting
Exercise and quality of life in cancer survivors
This study looks at how exercise habits are linked to how cancer survivors feel and their health outcomes. It may help understand if starting to exercise improves well-being.

Pleasanton, CaliforniaAges 45–75 - NCT06934239RecruitingPhase 4
AI-assisted vs. standard mammograms for breast cancer screening
This trial compares standard mammograms with mammograms aided by artificial intelligence (AI) to see if AI helps find breast cancer more accurately and reduces unnecessary callbacks. If you're 18 or older and getting a routine screening mammogram at one of the six participating health systems, you may be eligible.
Los Angeles, CaliforniaAges 18 years+ - NCT06942104RecruitingPhase 1
New imaging agent for advanced solid tumors
This trial tests a new imaging agent (18F-TRX) to see if it can better detect cancer spread in people with advanced solid tumors. It is designed for patients with specific cancers like high-grade brain tumors, advanced kidney cancer, or prostate cancer that has stopped responding to hormone therapy.
San Francisco, CaliforniaAges 18 years+ - NCT06900595RecruitingPhase 2
Cabozantinib with immunotherapy for advanced adrenal cancer
This trial tests adding the targeted drug cabozantinib to the immunotherapy cemiplimab for people with advanced adrenocortical carcinoma that cannot be removed by surgery or has spread. It checks if the combination works better than cabozantinib alone.
La Jolla, CaliforniaAges 12 years+ - NCT06896474Recruiting

Irvine, CaliforniaAges 18 years+ - NCT06801236RecruitingPhase 1
A new drug for advanced prostate cancer that has stopped responding to treatment
This early-phase trial tests a new study drug called ACE-232 for men with advanced prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. It aims to see if the drug is safe and may help slow the cancer.
La Jolla, CaliforniaAges 18 years+ - NCT06793215RecruitingPhase 3
Divarasib plus pembrolizumab for KRAS G12C lung cancer
This trial compares a new targeted drug (divarasib) combined with an immunotherapy (pembrolizumab) versus standard chemotherapy plus immunotherapy for people with advanced lung cancer that has a specific KRAS G12C mutation. It aims to see if the new combination works better and is safe.
Clovis, CaliforniaAges 18 years+ - NCT06795009RecruitingPhase 1
Zanzalintinib plus paclitaxel for recurrent uterine cancer
This trial combines an experimental pill called zanzalintinib with a standard chemotherapy (paclitaxel) for people with advanced or recurrent high-grade uterine cancer who have already tried platinum-based chemotherapy. The goal is to see if this combination can help shrink or control the cancer better than standard options alone.
San Francisco, CaliforniaAges 18 years+ - NCT06780787RecruitingPhase 2
Study of chemo plus immunotherapy for localized rectal cancer before surgery
This trial tests a combination of chemotherapy (FOLFOX) and two immunotherapies (botensilimab and balstilimab) before surgery for patients with localized rectal cancer. It aims to see if adding immunotherapy helps shrink the tumor and improve outcomes.
Duarte, CaliforniaAges 18 years+ - NCT06780176Recruiting
Breast cancer risk study for people in Florida
This study looks at breast cancer risk factors and outcomes by inviting people who are getting breast biopsies or are new breast patients at certain Florida hospitals to complete a survey. It aims to better understand what affects breast cancer risk and treatment results.
Los Angeles, CaliforniaAges 18 years+ - NCT06770582RecruitingPhase 2
Adding immunotherapy to radiation for bladder cancer
This trial tests whether adding the immunotherapy drug pembrolizumab to radiation therapy works as well as or better than the usual chemotherapy given with radiation for a type of bladder cancer that has not invaded the muscle. It is for people whose cancer came back or has high-risk features and who would otherwise need to have their bladder removed.
Bakersfield, CaliforniaAges 18 years+ - NCT06771219RecruitingPhase 1

Study of ECI830 for advanced breast cancer and solid tumors
This trial is testing a new drug called ECI830, either alone or with another drug, for people with advanced breast cancer or other solid tumors that have not responded to standard treatments. It may be an option if you have HR+/HER2- breast cancer, small cell lung cancer, or a tumor with a specific gene change (CCNE1 amplification).
Los Angeles, CaliforniaAges 18–100 - NCT06708429Recruiting

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.
