Recruiting studies in California
- NCT04895709RecruitingPhase 1/Phase 2
Testing a new cancer drug for advanced solid tumors
This early-phase trial tests how well a new drug (BMS-986340) works alone and combined with other treatments in people with advanced solid tumors that have progressed despite standard care. It also studies tumor samples to look for biomarkers that may predict who benefits.
Clovis, CaliforniaAges 18 years+ - NCT06682793RecruitingPhase 1/Phase 2
Study of A2B395 therapy for solid tumors with EGFR and HLA loss
This trial tests a new cell therapy called A2B395 for cancers that have EGFR, a protein on the cell surface, and have lost a specific marker called HLA-A*02. The therapy uses specially engineered immune cells to target and kill these cancer cells. This may help patients with colorectal, lung, head and neck, breast, kidney, or other solid tumors that are no longer responding to standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT05579366RecruitingPhase 1/Phase 2
Study of rinatabart sesutecan for advanced solid tumors
This trial tests an investigational drug called rinatabart sesutecan (also known as Rina-S) for people with advanced solid tumors, including ovarian, endometrial, lung, breast, and other cancers. The drug is designed to target and kill cancer cells, and the study aims to see if it is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT05985655RecruitingPhase 1/Phase 2
Study of GTAEXS617 for advanced solid tumors
This trial tests a new drug called GTAEXS617 for adults with certain advanced solid tumors that have not responded to standard treatments. It aims to see if the drug is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT05005403RecruitingPhase 1
Testing azirkitug for lung, head/neck, and other solid cancers
This Phase 1 study tests how a new medicine (azirkitug) behaves in the body and how safe it is, given by IV infusion alone or with other cancer drugs. It may help people with several advanced solid tumor cancers, especially after standard treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT07517198RecruitingPhase 1
EXS74539 Study for Advanced Solid Tumors
This is an early-stage study testing a new cancer drug called EXS74539 to find the right dose and see how well it works in people with various advanced solid tumors. The drug may help patients whose cancers have stopped responding to standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT06242470RecruitingPhase 1
Study of MGC026 for advanced solid tumors
This trial tests a new drug called MGC026 that targets a protein called B7-H3 on cancer cells, aiming to shrink or slow different advanced solid tumors. It is an early-phase study to find the right dose and check safety.

What taking part in a breast 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 breast tumor clinical trials in California?
- Yes. We're currently tracking 79 recruiting breast 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 breast 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 breast 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 breast 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.
