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+ - NCT06620302RecruitingPhase 1/Phase 2
Adding DT2216 to chemo for relapsed solid tumors and FLC
This trial is testing whether adding a new drug, DT2216, to standard chemotherapy can help treat solid tumors (not starting in the brain) or fibrolamellar carcinoma (FLC) that have come back or not responded to treatment. It's for children, teens, and young adults (ages 1 to 39).
Orange, CaliforniaAges 1–39 - NCT05772130Recruiting
Help family members get cancer genetic test results and counseling
This study tests a family-centered way to share cancer genetic testing results with close relatives, so more relatives get genetic counseling and testing. It may help your eligible family members understand their risk and get the right next steps.
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+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Arroyo Grande, CaliforniaAges 40–75 - NCT05564377RecruitingPhase 2
Find targeted cancer treatments using genetic testing
This study matches people with advanced solid tumors to targeted treatment plans based on genetic testing. It also requires tumor sample testing to help doctors choose the most promising therapy for your specific tumor changes.
Arroyo Grande, CaliforniaAges Any age - NCT07189195RecruitingPhase 1
TR-002 for advanced solid tumors and pancreatic cancer
This trial tests a new drug called TR-002 in people with advanced solid tumors (cancer that has spread) who have run out of standard treatment options. It includes a specific group for people with pancreatic cancer that is no longer responding to chemotherapy.
Sacramento, 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.
San Francisco, CaliforniaAges 1–21 - 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 - NCT02474160Recruiting
Banking cancer tissue and blood for future research
This study collects and stores leftover or newly taken samples of tissue and blood from people with cancer. The goal is to build a research library that can help investigators study cancer and develop better tests or treatments.
Duarte, CaliforniaAges 2 months+ - NCT02402244Recruiting
Caring registry study for children and young people with cancer
This study keeps a careful record of children, teens, and young adults with cancer (and some related growths) and may follow them over time. It helps researchers better track outcomes and future contact so care can improve.
Downey, CaliforniaAges Up to 25 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+ - NCT06268665RecruitingPhase 2
Tart Cherry Juice for Preventing Nerve Damage from Chemotherapy
This study tests whether tart cherry juice can help prevent nerve damage (peripheral neuropathy) caused by the chemotherapy drug paclitaxel. Participants drink tart cherry juice daily during their 12 weeks of paclitaxel treatment.
Sacramento, 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+ - 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+ - NCT06311214RecruitingPhase 2
Personalized ADC therapy for advanced solid tumors
This trial tests personalized antibody-drug conjugates (ADCs) for advanced solid tumors. It looks for specific proteins on your tumor cells to match you with a treatment that targets them directly.
Irvine, 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+ - 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+ - 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+ - NCT06549478RecruitingPhase 1

What taking part in a malignant 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.
