Recruiting studies in California
- NCT06246916RecruitingPhase 3
Testing a new immunotherapy combo for advanced melanoma
This trial is testing a combination of two immunotherapy drugs (anti-LAG-3 and anti-PD-1 antibodies) to see if they work better than standard treatment for people with advanced melanoma that hasn't been treated before. It may be an option if you have not yet received any systemic therapy for your melanoma.

Testing ARX788 for HER2-low advanced breast cancer
This trial tests a new drug, ARX788, for people with HER2-low breast cancer that has spread or cannot be removed by surgery. The goal is to see if ARX788 helps shrink or control the cancer.
San Francisco, CaliforniaAges 18 years+ - NCT06227377RecruitingPhase 1
A new drug for cancers with KRAS G12D mutation
This trial tests a new drug called QTX3034 in people whose cancer has a specific genetic change called KRAS G12D. The drug aims to block the mutated protein that helps cancer grow, and may work even if other treatments have stopped working.

Testing a new drug and procedure for advanced pancreatic cancer
This trial tests a new drug called mitazalimab injected directly into the tumor, combined with a special electrical procedure that kills cancer cells. It is for people whose pancreatic cancer has not spread but cannot be removed by surgery.
La Jolla, CaliforniaAges 18 years+ - NCT06103669Recruiting
Local treatment for limited cancer spread
This trial tests whether using local treatments (like targeted radiation or ablation) on a few new spots of cancer can help people whose cancer is otherwise stable on their current treatment. It enrolls people with various solid tumors, such as breast, gynecologic, head & neck, sarcoma, or other types.
Sacramento, CaliforniaAges 18 years+ - NCT06043817RecruitingPhase 1/Phase 2
Study of STX-721 for advanced lung cancer with EGFR or HER2 changes
This trial tests a new drug, STX-721, for people with advanced non-small cell lung cancer that has a specific genetic change (EGFR or HER2 exon 20 insertion). The study aims to see if the drug is safe and effective.
Irvine, 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+ - NCT05989828RecruitingPhase 1
Engineered immune cells for advanced triple-negative breast cancer
This trial tests a personalized treatment where your own immune cells are modified to recognize and attack cancer cells that have a specific marker called NY-ESO-1. It is for people with triple-negative breast cancer that has not responded to at least two prior treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT05789082RecruitingPhase 1/Phase 2
Divarasib for untreated lung cancer with KRAS G12C

Duarte, CaliforniaAges 18 years+ - NCT05797168RecruitingPhase 1/Phase 2
Early study drug for advanced solid tumors, alone or with another drug
This Phase 1/2 study tests a new AstraZeneca cancer drug (AZD5335) to see how safely it can be given and how well it works in people with advanced solid tumors. You may get it alone or with another treatment, and you’ll need to provide tumor information (sometimes including a biopsy) for study planning.
Duarte, CaliforniaAges 18–130 - 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+ - NCT05727904RecruitingPhase 3
New immunotherapy for advanced melanoma, with or without lifileucel
This trial studies whether adding lifileucel (a patient-specific immune-cell treatment) to pembrolizumab works better than pembrolizumab alone. It’s for people with untreated advanced melanoma that cannot be removed by surgery.
San Francisco, CaliforniaAges 18–70 - NCT05702229RecruitingPhase 2
Study of combined medicines for advanced stomach cancer with Claudin18.2
This Phase 2 study tests new combination treatments for advanced stomach or stomach-esophagus junction cancer that cannot be removed by surgery. It may help people whose tumors are positive for a marker called Claudin18.2, which the study uses to choose who can receive the treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT05655312RecruitingPhase 1/Phase 2
Targeted radiation melanoma treatment with or without nivolumab
This early-stage study tests whether a targeted radioactive drug can shrink advanced melanoma, either alone or along with nivolumab (an immune-activating medicine). You may be eligible if your melanoma shows a specific target on scan imaging and has progressed despite prior melanoma treatments.
Orange, CaliforniaAges 18–90 - NCT05646862RecruitingPhase 3

Study for bladder or urinary tract cancer after PD-1 failure
This Phase 1/2 study tests investigational cancer treatment(s) in people with locally advanced or metastatic urothelial cancer that has not responded to PD-1/PD-L1 immunotherapy. It may help by trying a new approach after prior checkpoint treatment has stopped working or the cancer returns.
Orange, CaliforniaAges 18 years+ - NCT05503797RecruitingPhase 2
Study of FORE8394 for cancers with BRAF changes
This trial tests a new drug, FORE8394, for people whose cancers have a change in the BRAF gene. It may be an option if you have a solid tumor or brain tumor that has not responded to other treatments.

Orange, CaliforniaAges 18 years+ - NCT05371132RecruitingPhase 1
PET scan study to track immune response after SBRT
This early (Phase 1) study uses a special PET scan to measure how your immune system responds after stereotactic body radiation therapy (SBRT). The goal is to see whether the scan result can serve as a marker of immune response, which may help future treatment planning.
Duarte, CaliforniaAges 18 years+ - NCT05168566RecruitingPhase 2
Sutetinib for lung cancer with a specific EGFR change
This Phase 2 study tests sutetinib capsules in people with advanced (locally advanced or metastatic) non-small cell lung cancer. It’s for tumors that have a specific, uncommon EGFR mutation, and aims to see how well the drug can control the cancer with limited prior chemotherapy.
Glendale, CaliforniaAges 18 years+ - NCT05125016RecruitingPhase 1/Phase 2
Study drug for advanced prostate cancer after standard treatments

What taking part in a advanced or metastatic solid tumors 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 or metastatic solid tumors clinical trials in California?
- Yes. We're currently tracking 701 recruiting advanced or metastatic solid tumors 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 or metastatic solid tumors 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 or metastatic solid tumors 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.
