Duarte, CaliforniaAges 18 years+ - NCT07630974RecruitingPhase 1/Phase 2
New Cancer Drug for Children With Hard-to-Treat Solid Tumors
This trial tests a new drug called ifinatamab deruxtecan in children whose solid tumors (cancers that form lumps, excluding brain tumors) have come back or stopped responding to previous treatments. The drug is designed to target and kill cancer cells while potentially causing fewer side effects than standard chemotherapy.
Los Angeles, CaliforniaAges 1 month–17 years - NCT07621614RecruitingPhase 2

NPX372 immunotherapy for advanced solid tumors
This trial tests NPX372, a new type of immunotherapy designed to fight several types of advanced cancer that haven't responded to standard treatments. It works by combining two immune signals to help your body's immune system recognize and attack cancer cells.
La Jolla, CaliforniaAges 19 years+ - NCT07505797Recruiting
Ultrasound imaging study for suspicious breast lesions
This study is testing a new ultrasound device (ATUSA) to see how well it can image breast lesions that have been classified as suspicious (BI-RADS 4 or 5). If you have a recent finding that needs further evaluation, this research might help improve detection methods.
Sacramento, CaliforniaAges 18–94 - NCT07489066RecruitingPhase 2
Study of PF-08634404 for early-stage or locally advanced lung cancer
This trial tests a new drug, PF-08634404, alone or with other treatments, for people with early-stage or locally advanced non-small cell lung cancer (NSCLC) that can be surgically removed or has been treated with radiation and chemo. It aims to find if the drug helps before or after surgery or after standard treatments.
Stanford, CaliforniaAges 18 years+ - NCT07476287RecruitingPhase 2
Study of PF08634404 plus chemo for transformed small cell lung cancer
This trial tests a new study drug (PF08634404) combined with standard chemotherapy for people whose non-small cell lung cancer has changed into a more aggressive form called small cell lung cancer. It hopes to improve outcomes by targeting the cancer in two ways.
Duarte, CaliforniaAges 18 years+ - NCT07470008Enrolling by invitation

What taking part in a neoplasms 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 neoplasms clinical trials in California?
- Yes. We're currently tracking 249 recruiting neoplasms 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 neoplasms 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 neoplasms 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 neoplasms 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.
