Recruiting studies in California
- NCT05696626RecruitingPhase 3
Test a new pill plus abemaciclib versus standard therapy
This Phase 3 study compares lasofoxifene plus abemaciclib versus fulvestrant plus abemaciclib for ER-positive, HER2-negative breast cancer that has an ESR1 mutation. It looks for better tumor control in people whose cancer has progressed on hormone therapy (an aromatase inhibitor) and who meet specific safety and testing requirements.

Los Angeles, CaliforniaAges 18 years+ - NCT05732831RecruitingPhase 1/Phase 2
Study drug for tumors with MTAP loss
This Phase 1/2 trial tests TNG462 (with or without pembrolizumab, depending on the plan) in solid tumors that have lost MTAP. The goal is to check safety and learn whether the treatment can help people with these specific tumor changes.
Palo Alto, CaliforniaAges 18 years+ - NCT05733598RecruitingPhase 2
RP2 plus standard treatment for advanced liver or bile cancers
This Phase 2 trial studies whether RP2, added to standard second-line treatment, can improve outcomes for people with advanced liver cancer or bile duct/gallbladder cancer.

What taking part in a locally advanced 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 clinical trials in California?
- Yes. We're currently tracking 122 recruiting locally advanced 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 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 locally advanced 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 locally advanced 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.
