Los Alamitos, CaliforniaAges 18 years+ - NCT07220187RecruitingPhase 3
Adding pirtobrutinib to usual treatment for newly diagnosed Richter transformation
This study tests whether adding a targeted drug called pirtobrutinib to the usual chemotherapy for Richter transformation can improve outcomes. It is a phase 3 trial, meaning it compares the new combination to the standard approach, and may help patients live longer or delay progression.
Irvine, CaliforniaAges 18 years+ - NCT07214532Recruiting
Using a blood test to guide breast cancer therapy
This study tests whether a blood test can help decide when to start additional hormone-blocking therapy for early-stage breast cancer. It aims to see if starting therapy only when the test detects cancer DNA is as effective as giving it to everyone.
Loma Linda, CaliforniaAges 18 years+ - NCT07218380RecruitingPhase 3
Study of Vepugratinib for advanced bladder or urinary tract cancer
This trial tests an experimental drug called Vepugratinib for people with advanced urinary tract cancer that has a specific change in the FGFR3 gene. It may be an option if you haven't had other treatments for advanced cancer and are looking for a new approach.
Irvine, CaliforniaAges 18 years+ - NCT07213804RecruitingPhase 3
Study of sofetabart mipitecan for ovarian cancer
This trial tests a new drug called sofetabart mipitecan for people with ovarian cancer that has come back after treatment. It is for those whose cancer is either resistant to platinum chemo (Part A) or sensitive to it (Parts B and C). The study will see if the drug can help shrink or slow the cancer.
Burbank, CaliforniaAges 18 years+ - NCT07217301RecruitingPhase 3
Comparing TAK-928 to docetaxel for advanced lung cancer
This study tests a new drug called TAK-928 against the standard chemo docetaxel for people with advanced squamous non-small cell lung cancer. You may be able to join if you have already tried a checkpoint inhibitor and platinum chemotherapy, and your cancer has grown.
Los Alamitos, CaliforniaAges 18 years+ - NCT07217262Recruiting

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.
