High-dose chemo and stem cell transplant for T-cell lymphoma patients in remission
This trial tests whether high-dose chemotherapy followed by a stem cell transplant using your own cells can help people with certain types of peripheral T-cell lymphoma live longer. You would qualify if you have already finished your first round of chemotherapy and are in complete remission.
Burbank, CaliforniaAges 18–75 - NCT07441681RecruitingPhase 3
Comparing radiation plus targeted therapy vs standard chemo for head and neck cancer
This trial compares two treatments for advanced head and neck cancer in patients who cannot take the drug cisplatin.

Duarte, CaliforniaAges 18 years+ - NCT07288112RecruitingPhase 1/Phase 2
Personalized immune vaccine for advanced melanoma
This trial tests a new personalized vaccine made from your own tumor cells. It's for people with advanced melanoma that hasn't responded to standard immunotherapy. The goal is to see if this vaccine can help your immune system fight the cancer.
Duarte, CaliforniaAges 18 years+ - NCT06580314RecruitingPhase 3
Olaparib with or without bevacizumab for ovarian cancer
This trial tests whether taking the drug olaparib for one or two years, alone or with another drug called bevacizumab, can help keep ovarian cancer from coming back after initial chemotherapy and surgery. It is for people with certain genetic markers in their tumor.
Antioch, CaliforniaAges 18 years+ - NCT04251052Recruiting
Compare two surgeries to lower ovarian cancer risk in BRCA1 carriers
This study compares two risk-reducing surgery plans for people with a BRCA1 genetic change to see which approach helps lower ovarian cancer risk. You may be asked to have the study procedure sooner or later depending on your chosen plan.
Antioch, CaliforniaAges 35–50 - NCT05976763RecruitingPhase 3
Testing continuous vs. intermittent zanubrutinib for older adults with mantle cell lymphoma
This trial tests whether taking the targeted drug zanubrutinib continuously is better than taking it on a schedule with breaks for older adults with untreated mantle cell lymphoma. The goal is to find a treatment that works while reducing side effects.
Beverly Hills, CaliforniaAges 60 years+ - NCT07279571Recruiting
AI chatbot education for gynecologic cancer patients
This trial uses an AI chatbot to help educate gynecologic oncology patients about HPV vaccination. It aims to see if the chatbot improves knowledge and vaccination rates.
Los Angeles, CaliforniaAges 18 years+ - NCT07512271Recruiting

This study tests a new computer-based education module created by artificial intelligence to help breast cancer patients understand their diagnosis and treatment options. The goal is to see if this tool helps patients feel more informed and prepared for their care.
San Francisco, CaliforniaAges 18 years+ - NCT06647953RecruitingPhase 3
Testing a standard approach for pleuropulmonary blastoma, with or without topotecan
This trial compares a standard surgery and chemotherapy plan for type I pleuropulmonary blastoma (PPB) to adding the drug topotecan for types II and III PPB. The goal is to see if the extra drug helps shrink tumors and improve outcomes for children with more advanced disease.
Downey, CaliforniaAges Up to 21 years - NCT07671534RecruitingPhase 2
Metronomic chemotherapy with gemcitabine, mitomycin C, and thalidomide for advanced solid tumors
This trial tests a combination of three drugs—gemcitabine, mitomycin C, and thalidomide—given in a low, frequent 'metronomic' schedule to treat advanced solid tumors that have already been treated. The goal is to see if this approach can slow or stop tumor growth with fewer side effects.
Santa Monica, CaliforniaAges 18 years+ - NCT06410209RecruitingPhase 2

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 135 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.
