Recruiting studies in California
- NCT07109726RecruitingPhase 1/Phase 2
Testing TER-2013 for advanced tumors with AKT/PI3K/PTEN changes
This trial tests a new drug called TER-2013, alone or combined with another drug (fulvestrant), for people with advanced solid tumors that have specific genetic changes in the AKT/PI3K/PTEN pathway. It aims to see if the drug is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT06172478RecruitingPhase 2
HER3-DXd for advanced solid tumors after prior treatment
This trial tests a new targeted drug called HER3-DXd for people with several types of advanced solid tumors that have stopped responding to standard treatments. The drug is an antibody-drug conjugate, designed to deliver chemotherapy directly to cancer cells that have a protein called HER3 on their surface.
Duarte, CaliforniaAges 18 years+ - NCT06004245RecruitingPhase 1
Study of VVD-133214 for advanced solid tumors
This trial tests an experimental drug called VVD-133214, alone or with other medicines, in people with advanced solid tumors that have specific DNA repair problems (MSI-H/dMMR). The goal is to see if it is safe and effective.
Duarte, CaliforniaAges 18 years+ - NCT06797336RecruitingPhase 1
Study of PT0253 for advanced KRAS G12D mutated tumors
This trial tests an experimental drug called PT0253 for people with advanced or metastatic cancers that have a specific genetic change called KRAS G12D. The drug may help shrink or slow the growth of these tumors, and the study will also check for side effects.
Los Angeles, CaliforniaAges 18 years+ - NCT06526819RecruitingPhase 1/Phase 2
New drug SMP-3124LP for advanced solid tumors
This trial tests a new drug called SMP-3124LP for people with advanced solid tumors that no longer respond to standard treatments. It is given in two phases: first to find the best dose (dose escalation) and then to see how well it works in specific cancer types (dose expansion).
Los Angeles, CaliforniaAges 18 years+ - NCT06880549RecruitingPhase 1
mRNA cancer vaccine study for advanced solid tumors
This study tests two new mRNA-based vaccines, alone or with other cancer drugs, in people with advanced solid tumors that have not responded to standard treatments. It aims to see if the vaccines are safe and can help shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT04939610RecruitingPhase 1/Phase 2
Studying a targeted radiation drug for advanced solid tumors
This trial tests how safe and effective a targeted radiation medicine (177Lu-FAP-2286) is for people with advanced solid cancers that have limited treatment options. It may help by delivering radiation directly to cancer-related targets and shrinking tumors.
Duarte, CaliforniaAges 18 years+ - NCT02555735Enrolling by invitation
Study of exceptional responders with solid tumors on chemotherapy
This study looks at people with solid tumor cancer (like many common carcinomas) to understand who responds exceptionally well to chemotherapy. You might be eligible if you are newly diagnosed or already receiving chemotherapy and can follow the study plan.
Los Angeles, CaliforniaAges 18 years+ - NCT07127874RecruitingPhase 1
Study of PHN-012 for advanced solid tumors
This trial tests a new drug called PHN-012 for people with advanced colorectal, non-small cell lung, or pancreatic cancer who have already tried at least one standard treatment. The goal is to see if the drug can help shrink or slow tumor growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06894745RecruitingPhase 1
PET imaging of solid tumors with 89Zr-DFO-starPEG
This early-phase trial tests a new imaging agent called 89Zr-DFO-starPEG that may help doctors see solid tumors more clearly on PET scans. It is a safety and imaging study, not a treatment, and may help find tumors in people with various types of cancer.
San Francisco, CaliforniaAges 18 years+ - NCT05471856RecruitingPhase 1
Test different doses of cancer drugs with ezabenlimab
This Phase 1 trial tests how different doses of a study drug (BI 1703880) work and how safe they are when given with ezabenlimab for advanced solid tumors. It’s for people whose cancer can’t be removed with surgery and who have tried standard treatments or can’t get them.
Los Angeles, CaliforniaAges 18 years+ - NCT04219254RecruitingPhase 1/Phase 2
Testing BI-1206 with pembrolizumab for advanced solid cancers
This early-phase trial studies BI-1206 together with pembrolizumab to treat advanced solid tumors. It may be an option if your cancer has progressed after prior anti–PD-1/PD-L1 treatment (or, in some groups, if standard treatments aren’t suitable).
Los Angeles, CaliforniaAges 18 years+ - NCT07671534RecruitingPhase 2
Metronomic chemotherapy with gemcitabine, mitomycin C, and thalidomide for advanced solid tumors
This trial tests a combination of three drugs—gemcitabine, mitomycin C, and thalidomide—given in a low, frequent 'metronomic' schedule to treat advanced solid tumors that have already been treated. The goal is to see if this approach can slow or stop tumor growth with fewer side effects.
Santa Monica, CaliforniaAges 18 years+ - NCT06710379RecruitingPhase 1
Testing ADRX-0405 for advanced solid tumors
This trial tests a new drug called ADRX-0405 in people with advanced solid tumors like prostate, stomach, or lung cancer. The goal is to see how safe it is and if it shrinks tumors.
Santa Monica, CaliforniaAges 18 years+ - NCT05101070RecruitingPhase 1/Phase 2
Study of an anti-cancer drug alone or with immunotherapy
This Phase 1/2 study tests a new cancer drug (S-531011) in people with advanced or metastatic solid tumors, either by itself or combined with an immunotherapy drug. It may help shrink tumors and learn how the treatment works, but it also requires extra procedures like repeat tumor biopsies and frequent monitoring.
Los Angeles, CaliforniaAges 18 years+ - NCT06014502RecruitingPhase 1
Study of IMGS-001 for advanced solid tumors that returned after treatment
This trial tests a new drug, IMGS-001, in people with advanced solid tumors that have grown back or not responded to standard treatments. It aims to find a safe dose and see if it helps shrink tumors.
Orange, CaliforniaAges 18 years+ - NCT07396584RecruitingPhase 1/Phase 2
HMPL-A580 for advanced or metastatic solid tumors
This trial tests a new drug called HMPL-A580 in people with advanced or metastatic solid tumors that cannot be removed by surgery. The goal is to see if it is safe and effective.

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.
Not the right time?
New solid tumor 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.
