Recruiting studies in California
- 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. It may help by training the immune system to better attack the cancer after the cancer has already grown despite prior treatment.
Beverly Hills, CaliforniaAges 18 years+ - NCT06060613RecruitingPhase 1/Phase 2
OBX-115 cell therapy for advanced melanoma or lung cancer
This trial tests an experimental cell therapy called OBX-115 for people with advanced melanoma or non-small cell lung cancer that has not responded to standard treatments. The therapy uses your own immune cells to fight the cancer. The study aims to see if it is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT05401110RecruitingPhase 1
Osimertinib plus antibody treatment for EGFR-mutated lung cancer
This Phase 1 study tests the combination of osimertinib (a targeted lung cancer pill) with an antibody called carotuximab to treat advanced EGFR-mutated non-small cell lung cancer. It aims to see whether adding the antibody can help when the cancer has grown despite prior EGFR-targeted therapy.
Beverly Hills, CaliforniaAges 18 years+ - NCT07064018RecruitingPhase 1/Phase 2
SPEDOX-6 for advanced solid tumors
This trial tests a new form of the chemotherapy drug doxorubicin, called SPEDOX-6, for people with certain advanced solid tumors that haven't responded to at least two prior treatments. The drug is designed to deliver doxorubicin directly to cancer cells while possibly reducing side effects.
Orange, CaliforniaAges 18 years+ - NCT06692738RecruitingPhase 3
Is a new immunotherapy better than Keytruda for squamous lung cancer?
This trial tests a new drug called Rilvegostomig against the standard drug pembrolizumab (Keytruda), both combined with chemotherapy, as a first treatment for advanced squamous non-small cell lung cancer. It aims to see which combination works better.
Anaheim, CaliforniaAges 18 years+ - NCT07140016RecruitingPhase 1
Study of gilteritinib for advanced ALK-positive lung cancer
This trial tests an oral drug called gilteritinib for people with advanced ALK-positive non-small cell lung cancer that has progressed after prior ALK inhibitor treatment. It aims to see if gilteritinib can help when other treatments have stopped working.
Fullerton, CaliforniaAges 18 years+ - NCT05920356RecruitingPhase 3
Tested KRAS-targeted sotorasib plus chemo vs pembrolizumab plus chemo
This Phase 3 trial tests whether sotorasib plus standard chemotherapy works better than pembrolizumab (an immunotherapy) plus standard chemotherapy as first treatment for certain advanced lung cancers. It may help people whose tumors have a KRAS G12C mutation and that do not show PD-L1 on testing.
Santa Barbara, CaliforniaAges 18–100 - NCT06427941RecruitingPhase 1
Study of BGB-B2033 drug for advanced solid tumors
This trial tests a new drug, BGB-B2033, alone or with other treatments, for people with advanced liver, stomach, lung, or germ cell cancers that have not responded to standard therapy. The goal is to see if the drug is safe and works against these tumors.
Duarte, CaliforniaAges 18 years+ - NCT06890338RecruitingPhase 2
Carboplatin and mirvetuximab for advanced ovarian cancer
This trial tests a combination of chemotherapy (carboplatin) and a targeted drug (mirvetuximab soravtansine) given through a vein. It is for people with newly diagnosed advanced ovarian, fallopian tube, or primary peritoneal cancer that has a specific protein called folate receptor alpha (FRα) on at least 75% of tumor cells.
Los Angeles, CaliforniaAges 18 years+ - NCT06926868RecruitingPhase 2/Phase 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.
Cerritos, CaliforniaAges 18 years+ - NCT06600906Recruiting
MRI test to predict treatment response in pancreatic cancer
This study is testing a new MRI technique that may help predict how well pancreatic cancer treatments will work. You would receive a special substance (called hyperpolarized pyruvate) during a standard MRI scan.
San Francisco, CaliforniaAges 18 years+ - NCT06010329RecruitingPhase 2
Study of a new pill for advanced lung cancer with rare EGFR mutations
This trial tests an experimental pill called Sutetinib for people with advanced non-small cell lung cancer that has a rare EGFR gene change. It aims to see if the drug can shrink tumors and improve survival.
Glendale, CaliforniaAges 18 years+ - 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.
Duarte, CaliforniaAges 16 years+ - NCT07028489Recruiting
Studying a standard-care comparison group for advanced EGFR-mutant lung cancer
This trial collects information from people with a specific type of advanced lung cancer to create a comparison group. It helps researchers understand how well new treatments work without giving any experimental medicine.
Monterey, CaliforniaAges 18 years+ - NCT05327010RecruitingPhase 2
Testing a new drug combination for advanced solid tumors
This trial is studying whether a new combination of two cancer drugs, ZEN003694 and talazoparib, can help people with advanced solid tumors that have not responded to other treatments. Talazoparib is a type of drug that targets cancer cells with certain DNA repair problems. The study is divided into groups based on specific gene mutations or previous treatment responses.
Duarte, CaliforniaAges 18 years+ - NCT06218914RecruitingPhase 1
Study of a new treatment for KRAS G12D cancers
This trial tests a new type of cell therapy (called TCR-T) that targets a specific genetic change (KRAS G12D) in advanced solid tumors that have stopped responding to standard treatments. It may be an option if your cancer has this mutation and you have a specific tissue type (HLA).
Duarte, CaliforniaAges 18 years+ - NCT06765109RecruitingPhase 3
Testing neladalkib for untreated ALK-positive lung cancer
This study tests a new pill called neladalkib to see if it works better than the current standard treatment (alectinib) for people with ALK-positive lung cancer who have not yet received any cancer therapy for advanced disease. It may be a good option if you have ALK-positive NSCLC and have not been treated before.
Newport Beach, CaliforniaAges 18 years+ - NCT05702229RecruitingPhase 2
Study of combined medicines for advanced stomach cancer with Claudin18.2

What taking part in a advanced 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 advanced cancer clinical trials in California?
- Yes. We're currently tracking 339 recruiting advanced 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 advanced 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 advanced 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 advanced 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.
