Recruiting studies in California
- NCT05327010RecruitingPhase 2
Testing a new drug combination for advanced solid tumors
This trial is studying whether a new combination of two cancer drugs, ZEN003694 and talazoparib, can help people with advanced solid tumors that have not responded to other treatments. Talazoparib is a type of drug that targets cancer cells with certain DNA repair problems. The study is divided into groups based on specific gene mutations or previous treatment responses.
Duarte, CaliforniaAges 18 years+ - NCT06126276RecruitingPhase 2
Testing neratinib with or without palbociclib for HER2+ solid tumors
This trial tests two targeted drugs—neratinib alone or with palbociclib—for people with HER2-positive solid tumors (other than breast cancer) that have returned or not gone away. The goal is to see if blocking HER2 and CDK4/6 can shrink or slow the tumor.
Encinitas, CaliforniaAges 18 years+ - NCT04119024RecruitingPhase 1
Gene-edited immune cells for advanced melanoma or solid tumors
This Phase 1 study tests a gene-modified immune cell treatment for advanced cancers that don’t have standard curative options. It may help by attacking cancer cells that show a specific marker called IL13Rα2 after patients receive “conditioning” chemotherapy to prepare the immune system.
Stanford, CaliforniaAges 18–75 - NCT04510051RecruitingPhase 1
CAR T cell therapy for IL13Rα2 positive pediatric brain tumors
This Phase 1 study tests a type of immune therapy (CAR T cells) for children with brain tumors that come back or do not respond to standard treatment. The cells are given after chemotherapy that temporarily lowers the body’s immune system, which may help the CAR T cells work better.
Los Angeles, CaliforniaAges 4–25 - NCT04870944RecruitingPhase 1/Phase 2
CBL0137 for children with advanced solid or brain tumors
This early-phase study tests CBL0137 in children and teens whose cancer has come back or is not responding to treatment. It is also for some specific hard-to-treat brain tumors, to see if the drug is safe and can work against the cancer.
Los Angeles, CaliforniaAges 1–21 - NCT05386108RecruitingPhase 1/Phase 2
Test abemaciclib plus elacestrant for breast cancer brain spread
This trial studies whether the combination of abemaciclib and elacestrant can slow or shrink ER-positive, HER2-negative breast cancer that has spread to the brain. It is designed for people whose cancer has progressed despite prior hormone (endocrine) treatment.
Fullerton, CaliforniaAges 18 years+ - NCT06118723Recruiting
Supramaximal vs maximal surgery for brain tumors
This trial compares removing as much tumor as safely possible (supramaximal resection) with standard maximal resection in people with high-grade glioma (an aggressive brain tumor). The goal is to see if more extensive removal improves survival and quality of life.
San Francisco, CaliforniaAges 18–90 - NCT06273176Recruiting
Surgery with or without brain mapping for recurrent glioblastoma
This study is testing whether using a special brain-mapping technique during surgery helps people with recurrent glioblastoma. It compares standard surgery to surgery with mapping to see if it leads to better outcomes for tumors near important brain areas.
San Francisco, CaliforniaAges Up to 90 years - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
Anaheim, CaliforniaAges 18 years+ - NCT06650163RecruitingPhase 1
New imaging test for brain tumor surgery planning
This trial tests a new kind of PET scan that uses a special tracer (Zr-89 crefmirlimab berdoxam) to help doctors see brain tumors more clearly before surgery. If you are scheduled to have your brain tumor removed, this scan may give your surgeon extra information to guide the operation.
Los Angeles, CaliforniaAges 18 years+ - NCT07339085Recruiting
Advanced MRI for brain tumor recurrence or radiation damage
This study uses advanced MRI scans to better tell the difference between a returning brain tumor and radiation injury. It may help guide your treatment decisions.
Los Angeles, CaliforniaAges 18 years+ - NCT05538130RecruitingPhase 1
Study medicine for BRAF-mutated advanced solid tumors
This Phase 1 trial studies how PF-07799544 works and what dose is safest in people with advanced cancer that has a specific genetic change called BRAF V600. You may receive it alone or with another treatment, depending on the tumor group, to see if it can treat the cancer.
Los Angeles, CaliforniaAges 16 years+ - NCT03510208RecruitingPhase 1/Phase 2
Uses a dye drug during brain or nerve tumor surgery
This trial tests whether a medicine with a fluorescent dye (panitumumab-IRDye800) helps doctors better see certain tumors during surgery. It may help safer, more complete tumor removal for people with glioblastoma or vestibular schwannoma.
Palo Alto, CaliforniaAges 18 years+ - NCT05687110RecruitingPhase 1
Testing novobiocin for tumors with DNA repair gene changes
This Phase 1 study tests whether novobiocin is safe and finds the best dose for people whose tumors have specific DNA repair gene mutations. It may help if your cancer is hard to treat with standard options, including certain patients who already tried PARP inhibitors.
Duarte, CaliforniaAges 18 years+ - NCT05691491RecruitingPhase 1/Phase 2
Temozolomide plus M1774 for advanced metastatic cancers
This Phase 1/2 trial tests a combination of temozolomide and M1774 to see how safe it is and whether it can help shrink advanced cancers that have spread. It focuses on certain tumor types and specific biomarker results, and it may be an option if standard treatments have been tried or aren’t possible.
Irvine, CaliforniaAges 18 years+ - NCT06549478RecruitingPhase 1
Radiation therapy guided by PET scan for painful bone cancer spread
This trial uses a special PET scan to guide radiation therapy for painful spots where cancer has spread to the bone. The goal is to treat the pain more precisely and see if this image-guided approach works well.
Duarte, CaliforniaAges 18 years+ - NCT05376878RecruitingPhase 4
PET/MRI scan to guide treatment in HER2+ brain metastatic breast cancer
This trial tests a special PET/MRI imaging scan using a labeled drug to help doctors evaluate HER2+ breast cancer that has spread to the brain. It focuses on patients who plan to receive fam-trastuzumab deruxtecan, a targeted cancer medicine, and aims to see how well the scan can support treatment decisions.
Duarte, CaliforniaAges 18 years+ - NCT04511013RecruitingPhase 2
Trial for BRAF-mutant melanoma spread to the brain
This Phase 2 study tests whether a 3-drug plan (encorafenib + binimetinib + nivolumab) works better than ipilimumab + nivolumab for melanoma that has spread to the brain. If you qualify, you’ll get either treatment and have frequent brain scans to track how well it controls the tumors.
Emeryville, CaliforniaAges 18 years+ - NCT04804644RecruitingPhase 3
Memory-sparing radiation for brain metastases in small cell lung cancer
This study tests whether focusing high-dose radiation only on brain tumor spots, while avoiding the hippocampus (a brain area important for memory), helps protect memory and thinking compared with standard whole-brain radiation. It’s for people with small cell lung cancer that has spread to the brain.
Anaheim, CaliforniaAges 18 years+ - NCT07619599RecruitingPhase 1
PET Scan to Track Lung Cancer Treatment Response
This study uses a special PET imaging scan to help doctors see how well pembrolizumab (an immunotherapy drug) is working against advanced non-small cell lung cancer. You'll receive the scan along with your regular pembrolizumab treatment and possible radiation therapy to help measure treatment response.
Duarte, CaliforniaAges 18 years+ - NCT03418961RecruitingPhase 3
Study of heart-risk management for metastatic HER2 breast cancer
This trial follows people with metastatic HER2-positive breast cancer who are at higher risk for heart damage while on HER2-targeted therapy. Some participants are randomly assigned to different monitoring/heart-protection approaches to see what best helps keep the heart safe.
Emeryville, CaliforniaAges 18 years+ - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Los Angeles, CaliforniaAges 12 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.
Irvine, CaliforniaAges 18 years+ - NCT05372614RecruitingPhase 1
Testing trastuzumab deruxtecan and neratinib for HER2-positive cancers
This trial tests a combination of two targeted drugs, trastuzumab deruxtecan (Enhertu) and neratinib, for people with solid tumors that have a HER2 gene change. The goal is to see if the combination is safe and works well for cancers that have not responded to at least one prior treatment.

What taking part in a malignant brain neoplasm 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.
