This trial tests a new pill called zongertinib, alone or with other drugs, for people with HER2-positive cancers (like breast, stomach, or colorectal cancer) that have spread and are no longer responding to standard treatments. The goal is to find the best dose and see if it can help shrink tumors or slow the disease.
Cerritos, CaliforniaAges 18 years+ - NCT06607458RecruitingPhase 2
Liver-focused chemo for metastatic colorectal cancer
This trial tests giving high-dose melphalan directly into the liver's blood supply, followed by standard cancer therapy, for people whose colorectal cancer has spread mainly to the liver. The goal is to see if this approach is safer and works better than standard treatment alone.
Santa Monica, CaliforniaAges 18 years+ - NCT05803382RecruitingPhase 1
Adding a new drug to capecitabine for metastatic colorectal cancer
This Phase 1 study tests a new anti-cancer drug (ZEN003694) added to the usual chemotherapy capecitabine. It is for adults with colorectal cancer (and possibly other cancers) that has spread or cannot be removed and has continued despite prior standard treatment.
Orange, CaliforniaAges 18 years+ - NCT06551116Recruiting
Better HER2 testing for HER2-low breast cancer on Enhertu
This study looks at using a more detailed lab test to measure HER2 levels in people with HER2-low metastatic breast cancer who are starting or have just started treatment with Enhertu. The goal is to see if this test can help doctors better understand who might benefit from Enhertu.
San Francisco, CaliforniaAges 18 years+ - NCT04787744RecruitingPhase 2/Phase 3
Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
Long Beach, CaliforniaAges 18 years+ - NCT07227415RecruitingPhase 1/Phase 2
Study of a new drug for advanced kidney cancer
This trial tests a new drug, PF-08634404, alone or with other cancer treatments, for adults with advanced kidney cancer that has not been treated before. It aims to see if the drug can help shrink tumors or stop them from growing.
Alhambra, CaliforniaAges 18 years+ - NCT07562152RecruitingPhase 3
Atebimetinib Plus Gemcitabine/Nab-Paclitaxel for New Pancreatic Cancer
This trial tests a combination of three drugs—atebimetinib (a new targeted therapy), gemcitabine, and nab-paclitaxel (two standard chemotherapy drugs)—as a first treatment for pancreatic cancer that has spread beyond the pancreas. The goal is to see if adding atebimetinib helps patients live longer and feel better.
Duarte, CaliforniaAges 18 years+ - NCT07491445RecruitingPhase 3
Daraxonrasib plus chemo for first-line metastatic pancreatic cancer

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.
