Recruiting studies in California
- NCT03547973RecruitingPhase 2
Study of sacituzumab govitecan for advanced or non-removable bladder cancer
This trial tests sacituzumab govitecan, an anti-cancer drug, for people with urothelial (bladder/urinary tract) cancer that has spread or can’t be removed with surgery. It’s designed for tumors that have been treated already in specific ways, to see if the medicine can shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT03990896RecruitingPhase 2
Talazoparib for metastatic breast cancer with BRCA body DNA changes
This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
San Francisco, CaliforniaAges 18 years+ - NCT06706921RecruitingPhase 4
Predicting treatment success with PET scans in prostate cancer
This study looks at whether a special PET scan can help predict how well a targeted radiation therapy (LuPSMA) works in men with advanced prostate cancer that has spread. You would get several PET scans before and after treatment to see if the scan results can forecast your outcome.
Los Angeles, CaliforniaAges 18 years+ - NCT04329494RecruitingPhase 1
Study of targeted drug delivery into the abdomen using PIPAC
This Phase 1 trial tests PIPAC, a way to deliver anti-cancer medicine directly into the abdomen using a minimally invasive procedure. It is for people with peritoneal spread from certain cancers to see whether this approach is safe and potentially helpful.
Duarte, CaliforniaAges 18 years+ - NCT06526299RecruitingPhase 2
Higher dose of targeted radiation for prostate cancer with low PSMA levels
This trial tests a higher dose of a radioactive drug (177Lu-PSMA-617) for men whose prostate cancer has spread and does not produce much of a protein called PSMA on scans. The goal is to see if a stronger dose can work better than the standard dose.
Sylmar, CaliforniaAges 18 years+ - NCT07452224RecruitingPhase 2
Combination treatment for advanced lung cancer
This trial tests a new drug, ILKN421H, combined with pembrolizumab (a type of immunotherapy) for people with advanced non-small cell lung cancer (NSCLC) that has not responded to standard treatments or has not been treated before. It aims to see if this combination can help shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06996782RecruitingPhase 1/Phase 2
Lung cancer study testing new combination treatments
This study tests a new drug (rilvegostomig) alone or with chemotherapy or another drug (ramucirumab) for advanced non-small cell lung cancer that has spread. It aims to see if these combinations work better than standard treatments.
Santa Rosa, CaliforniaAges 18 years+ - NCT07129993RecruitingPhase 2/Phase 3
Comparing two drug combinations for advanced bladder cancer
This trial tests a new drug combination (Dato-DXd plus chemotherapy) against a standard chemotherapy combination for advanced bladder cancer that has spread or cannot be removed by surgery. It is for people whose cancer has grown after treatment with the drugs enfortumab vedotin (Padcev) and pembrolizumab (Keytruda).
Fullerton, CaliforniaAges 18 years+ - NCT04802759RecruitingPhase 1/Phase 2
Testing drug combinations for recurrent or advanced ER-positive breast cancer
This early-phase trial tests several combinations of cancer medicines to slow or control ER-positive breast cancer that has returned or progressed. It also checks safety and whether tumor or blood biomarkers can help match the right treatment to the right person.
Duarte, CaliforniaAges 18 years+ - NCT07227168RecruitingPhase 1
Study of STRO-004 for advanced solid tumors
This trial tests a new drug called STRO-004 for people with advanced solid tumors (cancers that have spread or come back). It aims to see if the drug is safe and effective for those who have already tried other treatments.
San Diego, CaliforniaAges 18 years+ - NCT07144280RecruitingPhase 3
Study of a new drug vs docetaxel for advanced lung cancer
This trial tests a new experimental drug called PF-08046054/SGN-PDL1V against a standard chemotherapy (docetaxel) for people with a type of advanced lung cancer that has PD-L1 protein on at least 1% of tumor cells and has progressed after prior treatments. The goal is to see if the new drug works better or has fewer side effects.
Berkeley, CaliforniaAges 18 years+ - NCT07128680RecruitingPhase 1
Immunotherapy with or without a gut bacteria pill for kidney cancer
This trial tests whether adding a live bacteria pill (EXL01) to standard immunotherapy drugs (nivolumab and ipilimumab) helps treat advanced or metastatic kidney cancer that has clear cells. You may join if you have not had prior immunotherapy and your cancer has not been treated before (except possibly after surgery).
Duarte, CaliforniaAges 18 years+ - NCT06774963RecruitingPhase 1

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+ - NCT04205968RecruitingPhase 2
Testing ramucirumab with chemo for advanced small bowel cancer
This trial studies whether adding ramucirumab to chemotherapy (either paclitaxel or FOLFIRI) works better for advanced small bowel adenocarcinoma that has already been treated with certain prior medicines. It may help shrink tumors or slow cancer growth in people whose cancer has progressed.
Anaheim, CaliforniaAges 18 years+ - NCT07550088RecruitingPhase 2

San Francisco, CaliforniaAges 18 years+ - NCT05208047RecruitingPhase 3
CGT9486 plus sunitinib for advanced gastrointestinal stromal tumors
This trial tests whether adding a new drug called CGT9486 to sunitinib (a standard cancer drug) works better than sunitinib alone for gastrointestinal stromal tumors (GISTs) that have grown or spread. You may qualify if your GIST stopped responding to or caused problems with imatinib, an earlier treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT06630845Recruiting
Comparing two whole-body scan methods for metastatic cancer
This trial tests whether a newer type of MRI scan (called whole-body DWI) can work as well as a standard PET/CT scan (called FDG PET) for finding and monitoring cancer that has spread. If you have metastatic cancer and already have a scheduled PET/CT or other scan, you may be able to get both scans done, helping researchers compare the two methods.

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 364 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.
