Oncology clinical trials in California
We’re tracking 134 recruiting oncology studies with a site in California — including Phase 1, Phase 1/Phase 2, Phase 2, Phase 3 and Phase 4 studies, each written for real people, not researchers.
Recruiting studies in California
- NCT05080673Recruiting
Colonoscopy planning for small, noncancerous colon polyps
This trial tests whether people with 1–2 small, noncancerous colon polyps should get their next colonoscopy after 5 years or after 10 years. It may help reduce unnecessary procedures or find cancers earlier if the shorter interval is safer for you.
Anaheim, CaliforniaAges 45–70 - NCT07091617Recruiting
Better genetic testing for young adults with cancer
This study tests a new way to offer genetic testing to young adults (ages 18-39) who have or had cancer. The goal is to make it easier for you to learn if you have inherited gene changes that could affect your cancer and your family's health.
Arroyo Grande, CaliforniaAges 18 years+ - NCT07059884Recruiting
Exercise program to help people with cancer stay active
This trial tests a distance-based exercise program designed to help people on chemotherapy maintain their physical function and prevent disability. It is for patients with certain cancers who are working full-time and can participate in moderate physical activity.
Dublin, CaliforniaAges 18 years+ - NCT07303725Recruiting
Spectral CT scan during cancer tumor treatment
This study tests a special CT scan used during procedures to treat tumors, like blocking blood flow or burning the tumor. It may help doctors see tumors more clearly during the treatment.
Palo Alto, CaliforniaAges 18 years+ - NCT06805305RecruitingPhase 2
Immunotherapy for newly diagnosed glioblastoma
This trial tests a new personalized immunotherapy (DOC1021) for people with newly diagnosed glioblastoma. The treatment uses your own immune cells to attack the tumor and is given after surgery and with standard chemotherapy and radiation.
Newport Beach, CaliforniaAges 18 years+ - NCT04804644RecruitingPhase 3
Memory-sparing radiation for brain metastases in small cell lung cancer
This study tests whether focusing high-dose radiation only on brain tumor spots, while avoiding the hippocampus (a brain area important for memory), helps protect memory and thinking compared with standard whole-brain radiation. It’s for people with small cell lung cancer that has spread to the brain.
Anaheim, CaliforniaAges 18 years+ - NCT01790152Recruiting
Dexrazoxane study to monitor heart damage in cancer survivors
This study tests dexrazoxane (DRZ) to see how it affects blood and heart-related “biomarkers,” or measurable signs of heart damage, after cancer treatment. It mainly targets survivors who may be at risk for cardiomyopathy (heart muscle weakness) or related heart failure.
Palo Alto, CaliforniaAges Any age - NCT02402244Recruiting
Caring registry study for children and young people with cancer
This study keeps a careful record of children, teens, and young adults with cancer (and some related growths) and may follow them over time. It helps researchers better track outcomes and future contact so care can improve.
Downey, CaliforniaAges Up to 25 years - NCT02693535RecruitingPhase 2
Match FDA cancer drugs to a tumor gene change
This trial tests FDA-approved cancer medicines in people with advanced cancer whose tumor has a specific gene or protein abnormality. It tries to see whether targeting that tumor “fingerprint” can help when standard treatments no longer work.
Walnut Creek, CaliforniaAges 12 years+ - NCT03138161RecruitingPhase 1/Phase 2
Testing three medicines for previously treated soft-tissue sarcoma
This trial tests trabectedin plus ipilimumab and nivolumab in people with advanced soft-tissue sarcoma that has already been treated. It aims to see how well this combination works and how safely it can be given.
Santa Monica, CaliforniaAges 18 years+ - NCT05720117RecruitingPhase 1
Study drug for advanced solid tumors with limited treatments left
This Phase 1 study tests PYX-201 in people with advanced (grown or spread) solid cancers to see if it is safe and how it works. You may qualify if your cancer has had up to a couple of prior treatments and you can safely take study medicines and undergo required testing like a tumor biopsy.
Los Angeles, CaliforniaAges 18 years+ - NCT07226180Enrolling by invitation
Building models from your tumor to guide treatment
This trial takes a small sample of your tumor to grow a model in the lab. This model helps doctors test which treatments might work best for you.
Newport Beach, CaliforniaAges 18 years+ - NCT05303532Enrolling by invitationPhase 3
Continue durvalumab after finishing a prior cancer study
This study lets people who already finished (or can no longer continue) an earlier AstraZeneca cancer treatment study keep receiving durvalumab. It tests whether continuing the same kind of treatment on a regular schedule can help keep your cancer under control.
Newport Beach, CaliforniaAges 18–99 - NCT03244020Enrolling by invitationPhase 4
Aspirin or low-dose blood thinner after bone or leg surgery
This trial compares aspirin versus a low-dose injectable blood thinner (LMWH) to prevent blood clots after certain orthopedic cancer surgeries. It may help lower the risk of dangerous clotting while balancing bleeding and side effects.
Los Angeles, CaliforniaAges 18 years+

What taking part in a oncology 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 oncology clinical trials in California?
- Yes. We're currently tracking 134 recruiting oncology 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 oncology 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 oncology 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 oncology 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.
