Recruiting studies in California
- NCT07044570Recruiting
Examining attitudes in physical activity engagement
This trial tests if a program can help people who are not very active start and stick with a physical activity routine. Participants will wear a study-provided smartwatch to track their activity and answer brief surveys.
Los Angeles, CaliforniaAges 18 years+ - NCT07154706RecruitingPhase 3
Taletrectinib vs placebo after surgery for ROS1-positive lung cancer
This trial tests whether taletrectinib (a targeted pill) can help prevent lung cancer from coming back after surgery in people whose tumors have a ROS1 gene change. You would take either taletrectinib or a placebo (inactive pill) for about a year after surgery.
Orange, CaliforniaAges 18 years+ - NCT07164313RecruitingPhase 1
ZW251 for advanced solid tumors
This trial is testing a new drug called ZW251 for people with advanced liver cancer (hepatocellular carcinoma), non-small cell lung cancer, or germ cell tumors that have spread or cannot be removed by surgery. It aims to see if the drug is safe and effective.
San Francisco, CaliforniaAges 18 years+ - NCT07166406RecruitingPhase 3
Immunotherapy with or without targeted radiation for advanced liver cancer
This trial tests whether adding a precise, targeted form of radiation (called SBRT) to standard immunotherapy (atezolizumab and bevacizumab) can help people with advanced liver cancer that has spread to the blood vessels or outside the liver. You may be asked to participate in one of two treatment groups to see which approach works better.
Berkeley, CaliforniaAges 18 years+ - NCT07197554RecruitingPhase 1
A study of an experimental drug for advanced solid tumors
This trial tests a new drug, ST-01156, designed to attack cancer cells by breaking down a protein called RBM39. It may be an option for people with advanced solid tumors that have not responded to other treatments.
Duarte, CaliforniaAges 16 years+ - NCT07210086RecruitingPhase 2
PET scans to guide radiation for limited metastatic prostate cancer
This trial uses a special PET scan (POSLUMA) before and after radiation to see if it helps treat prostate cancer that has spread to a few spots outside the pelvis. It's for men whose cancer still responds to hormone therapy and who have not had widespread spread.
Duarte, CaliforniaAges 18 years+ - NCT07225738Recruiting
Multiple Myeloma treatment and cannabis use study
This study follows people with newly diagnosed multiple myeloma to see how their cancer treatments and use of medications, including cannabis, affect their health. It will help doctors learn more about what works best.
South Pasadena, CaliforniaAges 18 years+ - NCT07226843RecruitingPhase 1
Study of a new drug for adults with certain blood cancers
This trial tests a new drug, LY4584180, for adults with several types of non-Hodgkin lymphoma who have already had at least two prior treatments. The goal is to see if the drug can help shrink tumors and stop the cancer from growing.
Duarte, CaliforniaAges 18 years+ - NCT07310004Recruiting
VR vs Music for Breast Biopsy Anxiety
This trial compares using a virtual reality headset versus listening to relaxing music to help lower your anxiety and pain during a breast biopsy. Both methods are non-drug ways to help you feel more comfortable during the procedure.
Los Angeles, CaliforniaAges 18 years+ - NCT07339085Recruiting

Los Angeles, CaliforniaAges 18 years+ - NCT07291037RecruitingPhase 3
Study of datopotamab deruxtecan vs docetaxel for advanced lung cancer
This trial tests a new drug, datopotamab deruxtecan, against a standard chemotherapy (docetaxel) for people with advanced non-squamous lung cancer that has gotten worse after previous treatment. It is for those who do not have certain genetic changes (like EGFR, ALK, or ROS1) and whose tumors have a protein called TROP2.
Loma Linda, CaliforniaAges 18 years+ - NCT05142605Recruiting
Grief therapy for parents who lost a child to cancer
This study compares different grief-therapy approaches for parents (and their support people) after they lose a child diagnosed with cancer. It may help if your grief feels especially intense and long-lasting, and you are willing to take part in English telehealth sessions.
Stanford, CaliforniaAges 18 years+ - NCT07677839Recruiting
Study using ultrasound to look at normal lymph nodes before breast surgery
This study uses a special type of ultrasound (UHFUS) to take detailed images of your lymph nodes before and during breast cancer surgery. The goal is to better understand normal lymph node anatomy, which may help prevent lymphedema (swelling) after surgery.
Sacramento, CaliforniaAges 18 years+ - NCT07356154RecruitingPhase 1/Phase 2
Study of revumenib and mezigdomide for leukemia
This trial tests two experimental drugs, revumenib and mezigdomide, for people with acute leukemia that has certain genetic changes (NPM1, KMT2A, or NUP98) and has come back or not responded to prior treatment. The goal is to see if this combination can help control the leukemia.
Duarte, CaliforniaAges 12 years+ - NCT00349830Recruiting
Blood marker test to track response to cancer treatment
This study looks for new blood (serum) markers that may show whether anti-cancer therapy is working. If you have cancer or possible cancer and can safely take part, your blood may be used to monitor treatment response over time.
Stanford, 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 - NCT02250352Recruiting
Biopsy study to collect breast tumor tissue samples
This study takes small tissue samples (core biopsies) from people with known or suspected breast cancer and stores them for research. It may help scientists better understand breast tumors, especially when the cancer has spread.
Los Angeles, CaliforniaAges 18 years+ - NCT02674100Recruiting
Registry for pancreatic cancer patients getting a specific ablation
This is a research registry that collects information from adults with pancreatic cancer who are treated with an ablation procedure called irreversible electroporation (IRE). It may help doctors better understand which patients benefit from this approach and how the treatment is used in real life.
San Diego, CaliforniaAges 18 years+ - NCT02634645Recruiting
Treatment study for Barrett’s pre-cancer or esophageal cancer
This study looks at treatment options for people with Barrett’s esophagus that has progressed to abnormal cell growth (dysplasia) or cancer. It may help doctors compare approaches that use procedures to remove and/or destroy abnormal tissue in the esophagus.
Los Angeles, CaliforniaAges 18–100 - 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+ - NCT02660645Recruiting
Blue light bladder scan for suspected bladder cancer
This trial uses a special blue-light camera during a bladder procedure to help doctors better see non-muscle-invasive bladder cancer. It may help find cancer spots more clearly so they can be treated sooner.
Los Angeles, CaliforniaAges 18 years+ - NCT02701153Recruiting
Short pre-surgery radiation for soft-tissue sarcoma
This trial tests a short course of radiation before surgery to shrink a soft-tissue sarcoma and make it easier to remove. It may help by improving how well the tumor can be removed, while studying safety and effectiveness for this cancer type.
Los Angeles, CaliforniaAges 18 years+ - NCT03260842Recruiting

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 1,311 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.
