Recruiting studies in California
- 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 - NCT05317858RecruitingPhase 3
Open the brain’s blood barrier to treat lung cancer brain spots
This trial tests whether using focused ultrasound to temporarily open the brain’s blood barrier—plus standard immune therapy—can better treat non-small cell lung cancer (NSCLC) that has spread to the brain. It aims to help medicines reach the brain tumor spots more effectively, while still using the usual lung cancer treatment.
Newport Beach, CaliforniaAges 18–100 - NCT04423211RecruitingPhase 3
Surgery-recovered prostate cancer treated with PET-guided radiation
This trial tests whether adding targeted radiation guided by a PET scan (along with hormone therapy) can improve outcomes for prostate cancer that has come back after surgery. The PET scan helps doctors look for spots outside the usual radiation area so treatment can be tailored.
Arroyo Grande, CaliforniaAges 18 years+ - NCT07544654RecruitingPhase 3
Study comparing obrixtamig plus chemotherapy for advanced neuroendocrine cancer
This trial tests a new drug called obrixtamig combined with standard chemotherapy for advanced neuroendocrine cancer (a rare type of cancer).

Duarte, CaliforniaAges 18 years+ - NCT06467357RecruitingPhase 3
A study of T-DXd and rilvegostomig for HER2-positive bile duct cancer
This trial tests a new combination of two drugs (T-DXd and rilvegostomig) for people with advanced bile duct cancer that has not been treated before. The cancer must have high levels of a protein called HER2. This study compares the new drugs to standard treatments.

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+ - 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+ - NCT06357533RecruitingPhase 3
New drug combo for advanced lung cancer with high PD-L1
This trial tests a new two-drug combination (Dato-DXd and an immunotherapy called rilvegostomig) as the first treatment for people with advanced non-squamous lung cancer who have high PD-L1 levels. The goal is to see if this combination works better than current standard options.
Anaheim, CaliforniaAges 18 years+ - NCT07405801RecruitingPhase 2
Inavolisib plus ribociclib plus fulvestrant for advanced breast cancer
This trial tests a combination of three drugs (inavolisib, ribociclib, and fulvestrant) compared to a placebo plus two of the drugs (ribociclib and fulvestrant) for people with advanced hormone receptor-positive breast cancer who have not had prior treatment for advanced disease. The goal is to see if adding inavolisib improves outcomes.
Anaheim, CaliforniaAges 18 years+ - NCT07361510RecruitingPhase 3
Pumitamig vs Keytruda for advanced lung cancer with high PD-L1
This trial compares an experimental drug called Pumitamig with the approved immunotherapy drug Pembrolizumab (Keytruda) as the first treatment for advanced lung cancer that has high PD-L1 levels. The goal is to see which drug works better and has fewer side effects.

What taking part in a locally 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.
