Duarte, CaliforniaAges 18 years+ - NCT07514143Recruiting
Bladder Cancer Detection Study Using Urine Test
This study tests a new urine-based test called EpiCheck to help detect bladder cancer. You'll provide urine samples before or during a bladder procedure you're already scheduled to have, and researchers will see how well the test works.
San Diego, CaliforniaAges 22 years+ - NCT07505771RecruitingPhase 1
A study of 177Lu-IM-3050 for advanced solid tumors
This trial tests a new treatment called 177Lu-IM-3050 for people with advanced solid tumors that have not responded to or stopped working with standard treatments. The treatment targets a protein called FAP found on some cancer cells and may help shrink tumors or slow their growth.
Palo Alto, CaliforniaAges 18 years+ - NCT07506239Recruiting
Laser therapy for low-grade brain tumors in young people
This trial tests a laser treatment called LITT for low-grade glioma (a type of brain tumor) that has come back or is growing despite prior treatment. It aims to see if the laser is safe and effective in young people aged 2 to 25.

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.
