San Diego, CaliforniaAges 18 years+ - NCT05872295RecruitingPhase 1
Study drug for HER2-positive advanced cancers
This Phase 1 trial tests IKS014 to see how safe it is and how well it works in advanced solid tumors that have HER2. You may be eligible if your tumor is HER2-positive (including certain “low HER2” types) and your body’s blood counts and organ function are strong enough.
Newport Beach, CaliforniaAges 18 years+ - NCT07287917RecruitingPhase 1/Phase 2
Testing a new drug combo for advanced breast cancer or melanoma
This trial tests a new combination of drugs (AMXT 1501, DFMO, and standard therapies) for people with advanced solid tumors, specifically breast cancer (ER+ HER2-) or melanoma that has progressed after other treatments.

ORIC-114 for advanced lung or breast cancers with EGFR or HER2 changes
This early-phase study tests ORIC-114 to treat advanced solid tumors that have certain EGFR or HER2 genetic changes, often found in lung and breast cancers. It may help by targeting those specific cancer mutations, especially when standard treatments no longer work or aren’t tolerated.
Huntington Beach, CaliforniaAges 18 years+ - NCT04871542Recruiting
Predicting risk of immune therapy side effects
This study tries to predict who is more likely to get serious side effects from immune checkpoint medicines used for solid tumors. You may help researchers by answering questionnaires before treatment and during follow-up, and by possibly storing sample specimens.

What taking part in a solid tumor 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 solid tumor cancer clinical trials in California?
- Yes. We're currently tracking 313 recruiting solid tumor 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 solid tumor 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 solid tumor 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.
