Recruiting studies in California
- NCT04996875RecruitingPhase 2
Bezuclastinib for advanced mast cell disease
This Phase 2 study tests bezuclastinib, a targeted medicine, in people with advanced systemic mastocytosis (including certain advanced forms with blood cancers). It aims to shrink measurable disease and improve symptoms, while helping people who may also need treatment for an associated blood cancer.
Duarte, CaliforniaAges 18 years+ - NCT05283226RecruitingPhase 2
Oral anti-cancer pill plus paclitaxel after immunotherapy failure
This Phase 2 trial studies an oral study drug (NRC-2694-A) given with paclitaxel to treat head and neck squamous cell cancer that has come back or spread after immunotherapy.

Los Angeles, CaliforniaAges 18 years+ - NCT05318469RecruitingPhase 1/Phase 2
Ivermectin with immunotherapy for metastatic triple-negative breast cancer
This trial studies whether ivermectin, given together with immunotherapy (balstilimab or pembrolizumab), can help treat metastatic triple-negative breast cancer. It mainly looks at safety first, and may also explore how well the treatment works for people whose cancer has spread.
Los Angeles, CaliforniaAges 18 years+ - NCT05396872Recruiting
Decision-making study about gene testing for advanced prostate cancer
This study looks at how Veterans with advanced prostate cancer make decisions about gene testing and possible targeted treatments, and how patients and caregivers understand the information. It may help by improving decision support for people facing germline and tumor testing choices.
San Francisco, CaliforniaAges 18 years+ - NCT05524584RecruitingPhase 2
Anastrozole, fulvestrant, and abemaciclib for hormone-positive breast cancer
This trial tests whether combining three medicines can better control hormone-receptor–positive, HER2-negative metastatic breast cancer that cannot be cured with surgery or radiation. It may help shrink tumors and slow disease growth compared with standard hormone therapy approaches.
Orange, CaliforniaAges 18 years+ - NCT05624996RecruitingPhase 3
Targeted high-dose radiation added to standard lung cancer treatment
This trial tests whether adding high-dose, targeted radiation to the usual treatment helps people with locally advanced, non-operable lung cancer live longer or better control the cancer. It may help shrink tumors in the chest and improve outcomes when surgery can’t be done.
Bakersfield, CaliforniaAges 18 years+ - NCT05680987Recruiting
Surgery method study for certain thighbone fractures
This study looks at a specific surgical fixation method (how the thighbone pieces are held together) for distal femur or femoral shaft fractures. It aims to compare outcomes and see if this approach works well, especially by tracking results after surgery.
San Diego, CaliforniaAges 18 years+ - NCT05727176RecruitingPhase 2
Futibatinib for advanced bile duct cancer with FGFR2 changes
This trial tests futibatinib, a targeted pill, in people with advanced (unresectable) or metastatic bile duct cancer that has an FGFR2 fusion or rearrangement. It may help shrink tumors after standard chemotherapy has stopped working.
La Jolla, CaliforniaAges 18 years+ - NCT05746208RecruitingPhase 2
Lenvatinib plus pembrolizumab for advanced grade 3 NET tumors
This trial studies lenvatinib plus pembrolizumab to treat well-differentiated grade 3 neuroendocrine tumors (NETs) that cannot be fully removed by surgery or are locally advanced. It aims to shrink the tumor or slow its growth after the disease shows progression.
San Francisco, CaliforniaAges 18 years+ - NCT05766748RecruitingPhase 1/Phase 2
Azeliragon trial for pancreatic cancer after prior treatments failed
This trial tests azeliragon in people whose pancreatic cancer has spread or grown locally and who did not respond well to earlier chemotherapy. It aims to see whether the drug can help control the cancer and be tolerated after prior treatment.
Los Angeles, CaliforniaAges 18–80 - NCT05805371RecruitingPhase 1
PSCA CAR-T cells with or without radiation for prostate cancer
This Phase 1 study tests a prostate cancer treatment made of PSCA-targeted CAR-T cells, with or without radiation, to help control advanced prostate cancer. It aims to find a safe treatment approach and see how well it works in people whose cancer has PSCA.
Duarte, CaliforniaAges 18 years+ - NCT05808634RecruitingPhase 1
Testing an investigational drug for advanced lung or gut cancer
This Phase 1 trial tests BA3182, an investigational medicine, in people with advanced adenocarcinoma that cannot be removed by surgery. The goal is to see how the treatment works and whether it’s tolerated, and it may offer an option when standard options have been limited.
Los Angeles, CaliforniaAges 18 years+ - NCT06029270RecruitingPhase 2
Adding relatlimab to standard immunotherapy for nasopharyngeal cancer
This trial tests whether adding a new drug called relatlimab to the usual immunotherapy (nivolumab) helps people with nasopharyngeal cancer that has returned or spread. You will get standard chemotherapy plus nivolumab first, then if it works, you may be randomly assigned to get nivolumab alone or with relatlimab.
Dublin, CaliforniaAges 18 years+ - NCT06064877RecruitingPhase 3
Study of ficlatuzumab plus cetuximab for advanced head and neck cancer
This trial tests a combination of two drugs, ficlatuzumab and cetuximab, for people with recurrent or metastatic head and neck cancer that is HPV-negative and has not responded to prior immunotherapy and chemotherapy. It aims to see if this combination can help shrink tumors or slow the disease.
Los Angeles, CaliforniaAges 18 years+ - NCT06099769RecruitingPhase 2
Testing enzalutamide with or without mifepristone for AR-positive breast cancer
This trial tests if adding the drug mifepristone to the standard antiandrogen enzalutamide works better than enzalutamide alone or chemotherapy for people with a specific type of breast cancer that has androgen receptors. It aims to find a new targeted treatment option for triple-negative or ER-low breast cancer.
San Francisco, CaliforniaAges 18 years+ - NCT06118086RecruitingPhase 1/Phase 2
Study of REM-422 for advanced adenoid cystic carcinoma
This trial tests an experimental drug called REM-422 for people with adenoid cystic carcinoma (ACC) that has spread, come back, or cannot be removed by surgery. The study has two parts: an early part for people with advanced ACC and a later part for those with a specific genetic change (MYB biomarker) in their tumor. The goal is to see if REM-422 can slow or stop cancer growth.

This trial tests whether a precise radiation treatment (SBRT) can target a few growing spots of estrogen receptor-positive breast cancer that has spread to other parts of the body. It also uses a special PET scan (FES PET/CT) to see how well the cancer responds. The goal is to slow down the cancer and delay the need for stronger treatments.
Duarte, CaliforniaAges 18 years+ - NCT06454383RecruitingPhase 1
Gemcitabine and leflunomide for advanced pancreatic cancer

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.

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.
