Recruiting studies in California
- NCT07195916RecruitingPhase 1
Testing a new drug for advanced solid tumors and blood cancers
This trial tests a new drug called INCA036873, which targets CD70 on cancer cells, for people with advanced solid tumors or certain blood cancers that have not responded to prior treatments. The goal is to see if it is safe and effective against these tough-to-treat cancers.

What taking part in a solid tumor 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 solid tumor clinical trials in California?
- Yes. We're currently tracking 328 recruiting solid tumor 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 solid tumor 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 solid tumor 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 solid tumor 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.
