Recruiting studies in California
- NCT04300556RecruitingPhase 1/Phase 2
Testing an antibody-drug for advanced certain cancers
This early-phase trial tests a treatment called MORAb-202, an antibody “delivery” drug, to see if it’s safe and can help shrink or control certain advanced cancers. It may help people whose tumors match the study’s specific cancer types and prior treatment history.
Palo Alto, CaliforniaAges 18 years+ - NCT04924075RecruitingPhase 2
Belzutifan for cancers linked to VHL or HIF-2α changes
This Phase 2 study tests belzutifan (MK-6482) to treat certain advanced cancers caused by specific gene or disease changes, including VHL-related tumors and HIF-2α related tumors. It may help shrink tumors or slow their growth in people whose cancer matches these genetic or disease patterns.
Los Angeles, CaliforniaAges 12 years+ - NCT04282044RecruitingPhase 1
CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.
Stanford, CaliforniaAges 18 years+ - NCT07207707RecruitingPhase 1
KQB548 for advanced solid tumors with KRAS G12D mutation
This trial tests a new drug called KQB548 for people with certain advanced cancers (pancreatic, colorectal, or lung) that have a specific genetic change called KRAS G12D. It's for those whose cancer has continued to grow despite previous treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT06994806RecruitingPhase 1
KQB168 for advanced solid tumors post immunotherapy
This trial tests a new oral drug (KQB168) given alone or with other medicines for people with advanced solid tumors that have not responded to immunotherapy. The goal is to see if it is safe and can help shrink or slow the growth of cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT05733949RecruitingEarly Phase 1
Targeted radiation for people with many solid tumor metastases
This trial tests a precise type of radiation that targets multiple tumor spots in a carefully planned way. It may help people with many metastatic (spread) solid tumors when standard treatments aren’t working or can’t be used.
Duarte, 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+ - NCT05227326RecruitingPhase 1
A new drug for solid cancers that did not respond to usual care
This early-stage (Phase 1) trial tests AOH1996 in adults with solid tumors that have stopped responding to standard treatments. It’s meant to find a safe dose and see if the drug can help, especially in cancers with limited options.
Long Beach, CaliforniaAges 18 years+ - NCT04851119RecruitingPhase 1/Phase 2
Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Palo Alto, CaliforniaAges 1–30 - NCT04870944RecruitingPhase 1/Phase 2
CBL0137 for children with advanced solid or brain tumors
This early-phase study tests CBL0137 in children and teens whose cancer has come back or is not responding to treatment. It is also for some specific hard-to-treat brain tumors, to see if the drug is safe and can work against the cancer.
Los Angeles, CaliforniaAges 1–21 - NCT07197554RecruitingPhase 1
A study of an experimental drug for advanced solid tumors
This trial tests a new drug, ST-01156, designed to attack cancer cells by breaking down a protein called RBM39. It may be an option for people with advanced solid tumors that have not responded to other treatments.
Newport Beach, CaliforniaAges 16 years+ - NCT04192344RecruitingPhase 1
First test of an anti-cancer drug for advanced solid tumors
This Phase 1 study tests how safe a new drug (ABSK-021) is, what side effects it causes, and how the body processes it in people with advanced solid tumors. You may be eligible if your cancer has grown despite standard treatments or if no standard treatment exists.
Beverly Hills, CaliforniaAges 18 years+ - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Arroyo Grande, CaliforniaAges Any age - NCT06276491RecruitingPhase 1
Safety study of an investigational drug for advanced cancer with the CLDN6 marker
This trial tests an investigational drug for people with advanced solid tumors, especially ovarian, fallopian tube, peritoneal, endometrial, or germ cell cancers that have a specific marker called CLDN6. The goal is to see if the drug is safe and tolerable.
Duarte, CaliforniaAges 15 years+ - NCT07189195RecruitingPhase 1
TR-002 for advanced solid tumors and pancreatic cancer
This trial tests a new drug called TR-002 in people with advanced solid tumors (cancer that has spread) who have run out of standard treatment options. It includes a specific group for people with pancreatic cancer that is no longer responding to chemotherapy.
Sacramento, CaliforniaAges 18 years+ - NCT06751329RecruitingPhase 1/Phase 2
Study of DM002 for advanced solid tumors
This trial tests a new drug called DM002 for people with advanced solid tumors that have not responded to standard treatments. The drug targets two proteins (MUC1 and HER3) found on some cancer cells, and may help shrink tumors or slow their growth.
San Francisco, CaliforniaAges 18 years+ - NCT06311214RecruitingPhase 2

Testing neratinib with or without palbociclib for HER2+ solid tumors
This trial tests two targeted drugs—neratinib alone or with palbociclib—for people with HER2-positive solid tumors (other than breast cancer) that have returned or not gone away. The goal is to see if blocking HER2 and CDK4/6 can shrink or slow the tumor.
Encinitas, CaliforniaAges 18 years+ - NCT04890613RecruitingPhase 1
CX-5461 for cancers with BRCA or HRD gene changes
This Phase 1 trial tests CX-5461, a new cancer medicine, in people with certain solid tumors that have BRCA1/2 or related “HRD” gene mutations. The goal is to find out how the drug works, what dose is tolerable, and whether it can help shrink tumors.

What taking part in a solid 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 solid tumor clinical trials in California?
- Yes. We're currently tracking 333 recruiting solid 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 solid 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 solid 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 solid 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.
