Recruiting studies in California
- NCT04305834RecruitingPhase 2
Abemaciclib plus hormone pills for metastatic breast cancer in older adults
This Phase 2 study tests whether abemaciclib combined with standard hormone (endocrine) therapy can better control metastatic breast cancer in people age 70 and older. It may help if your cancer has already grown despite prior hormone therapy and/or other cancer medicines.

Flexible dosing of Lu-PSMA for advanced prostate cancer
This trial tests a flexible dosing schedule of a targeted radiation drug (Lu-PSMA) for men with metastatic prostate cancer that has stopped responding to hormone therapy and chemotherapy. It aims to see if adjusting the treatment schedule can improve outcomes while reducing side effects.
Los Angeles, CaliforniaAges 18 years+ - NCT07012031RecruitingPhase 1/Phase 2
Sotorasib and trastuzumab deruxtecan for KRAS G12C lung cancer
This trial tests a combination of two drugs, sotorasib and trastuzumab deruxtecan, for people with advanced or metastatic non-small cell lung cancer that has a KRAS G12C mutation. It may be an option if you've already had treatment with a KRAS G12C inhibitor, immunotherapy, and chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT06288113RecruitingPhase 2
Re-treatment with 177Lu-PSMA-617 for prostate cancer
This trial tests if a second round of a targeted radiation therapy (177Lu-PSMA-617) can help men whose prostate cancer has returned after a successful first treatment. It is for men whose cancer has stopped responding to hormone therapy and chemotherapy, and whose PSA levels have risen again after a prior good response to this drug.
Los Angeles, CaliforniaAges Any age - NCT05176483RecruitingPhase 1
New drug combinations for advanced solid tumors
This trial tests a new drug called zanzalintinib, which may slow or shrink various types of advanced cancer. It is given together with other cancer treatments, and the study is looking at many different cancers including kidney, prostate, bladder, lung, liver, and more.

Torrance, CaliforniaAges 18 years+ - NCT07711002RecruitingPhase 3
Saruparib with standard therapy for metastatic hormone-sensitive prostate cancer
This trial tests a new drug called saruparib, which may help keep prostate cancer from growing. It is for men whose cancer has spread and who have already received certain treatments. The study combines saruparib with a standard hormone therapy to see if it works better than the hormone therapy alone.
Beverly Hills, CaliforniaAges 18 years+ - NCT07225946RecruitingPhase 3

Study of a new drug versus chemotherapy for advanced triple-negative breast cancer
This trial tests a new investigational drug called izalontamab brengitecan against standard chemotherapy for people with advanced triple-negative breast cancer who cannot receive immunotherapy. The goal is to see if the new drug works better at shrinking or slowing the cancer.
Newport Beach, CaliforniaAges 18 years+ - NCT06662786RecruitingPhase 3
Amivantamab plus chemo vs. standard chemo for left-sided colorectal cancer
This trial compares a new combination (amivantamab plus chemotherapy) with the standard treatment (cetuximab plus chemotherapy) as the first therapy for people with left-sided colorectal cancer that has spread.

Glendale, CaliforniaAges 18 years+ - NCT04686305RecruitingPhase 1
Test drug T-DXd plus immunotherapy, with or without chemotherapy for HER2+ lung cancer
This Phase 1 study tests the safety (and early effectiveness) of T-DXd combined with immunotherapy, sometimes also with chemotherapy, in people with advanced lung cancer that is HER2-positive.

What taking part in a metastatic 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 metastatic cancer clinical trials in California?
- Yes. We're currently tracking 373 recruiting metastatic 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 metastatic 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 metastatic 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.
Not the right time?
New metastatic cancer 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.
