Recruiting studies in California
- NCT06084481RecruitingPhase 1
Study of a new drug for advanced solid tumors
This study tests a new intravenous drug called ABBV-400 in people with certain advanced solid tumors that have not responded to other treatments. The goal is to see if it can slow or stop tumor growth and to check for side effects.

What taking part in a locally advanced 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 locally advanced solid tumor clinical trials in California?
- Yes. We're currently tracking 232 recruiting locally advanced 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 locally advanced solid tumor study in California?

- 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 locally advanced 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.
