Recruiting studies in California
- NCT05687123RecruitingPhase 1
Adding sunitinib to Lutathera for pancreatic neuroendocrine tumors
This early-phase study tests whether adding sunitinib (a targeted pill) to Lutathera (a radioactive treatment) works better for people with advanced pancreatic neuroendocrine tumors. It also checks safety, since this combination has not been widely studied yet.
Duarte, CaliforniaAges 18 years+ - NCT05642611RecruitingPhase 3
Cooling and compression for nerve protection during chemotherapy
This study tests whether using cooling and/or compression on the arms or legs can prevent nerve damage that can happen from certain chemotherapy drugs. If you get eligible chemo soon, this may help lower the chance of painful numbness or tingling during treatment.
Martinez, CaliforniaAges 18 years+ - NCT05612347Recruiting
Compare stool test vs colonoscopy for older adults with polyps
This study compares two ways to check for colon polyps in older adults: using a stool test versus having a colonoscopy. It may help find a simpler option if you only had a small number of lower-risk polyps before.
San Diego, CaliforniaAges 65–82 - NCT05564390RecruitingPhase 2
MyeloMATCH screening to match you to AML or MDS treatment
This study screens people with newly suspected acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) to see which treatment approach fits best—either a specific study treatment or standard care. It may help by directing you to the right option and by sharing your blood/bone marrow samples for research.
Berkeley, CaliforniaAges 18 years+ - NCT05554406RecruitingPhase 2
New drug therapy for high-risk AML
This trial is testing new drug combinations for people with newly diagnosed, high-risk AML who have not yet started treatment. It aims to find more effective therapies for this aggressive form of leukemia.
Berkeley, CaliforniaAges 18–59 - NCT05519878Recruiting
Light plus job therapy for fatigue in genitourinary cancer
This trial tests whether light therapy and an occupational therapy fatigue program can reduce fatigue in people with certain urinary-system cancers who still have mild fatigue during treatment. It may help you feel more energized and manage day-to-day activity while cancer treatment is ongoing.
Duarte, CaliforniaAges 18 years+ - NCT05040360RecruitingPhase 2
Chemotherapy after surgery for high-risk pancreatic NET tumors
This Phase 2 trial studies whether giving chemotherapy after surgery can lower cancer recurrence risk in people with high-risk pancreatic neuroendocrine tumors (NETs). It may help you by testing an added treatment after the tumor has been removed.
Buena Park, CaliforniaAges 18 years+ - NCT05422911RecruitingPhase 2
Abiraterone, enzalutamide, or apalutamide for early castration prostate cancer
This Phase 2 trial tests whether abiraterone, enzalutamide, or apalutamide can work better (or differently) in men with prostate cancer that is considered “castration-sensitive.” It compares these hormone-blocking treatments to find an approach that controls the cancer more effectively and safely.
Los Angeles, CaliforniaAges 18 years+ - NCT05443425RecruitingPhase 1
Leflunomide plus steroids for acute graft-versus-host disease
This early-phase trial tests whether adding leflunomide to standard steroid treatment can better control acute graft-versus-host disease (aGvHD) after a stem cell transplant. It may help reduce the immune reaction that damages the body while keeping treatment safe and manageable.
Duarte, CaliforniaAges 18 years+ - NCT05371132RecruitingPhase 1
PET scan study to track immune response after SBRT
This early (Phase 1) study uses a special PET scan to measure how your immune system responds after stereotactic body radiation therapy (SBRT). The goal is to see whether the scan result can serve as a marker of immune response, which may help future treatment planning.
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+ - NCT05285358RecruitingPhase 1
Aerosol chemo plus standard drugs for bile duct and gallbladder cancer
This trial tests a new way to give the drug paclitaxel directly into your belly as a mist, along with two standard chemo drugs given through your veins, for bile duct or gallbladder cancer that has spread to the lining of the belly. The goal is to see if this approach can better control the cancer in the belly.
Duarte, CaliforniaAges 18 years+ - NCT05235165RecruitingPhase 3
Surgery choice for lung spread of osteosarcoma
This Phase 3 trial compares two ways to remove lung metastases (open surgery vs keyhole surgery) in people with osteosarcoma. It aims to see which approach works better and is safer for patients with a limited number of lung spots that can be removed.
Downey, CaliforniaAges Up to 50 years - NCT05253651RecruitingPhase 3
Tucatinib plus trastuzumab with chemo for HER2+ metastatic colon cancer
This trial tests whether adding tucatinib and trastuzumab to standard chemotherapy works better than standard treatment alone for people with HER2-positive metastatic colon or rectal cancer. It aims to improve how long people live and how well tumors respond as first treatment for advanced disease.
Pasadena, CaliforniaAges 18 years+ - NCT05208762RecruitingPhase 1
PD-L1 antibody drug study for advanced lung and head/neck cancers
This Phase 1 trial tests a new experimental drug (PF-08046054/SGN-PDL1V) in people with advanced solid tumors that have not responded to standard treatment or can’t use it. It is designed to see how the drug works and how safe it is, with a focus on tumors that have PD-L1 seen on prior lab testing.
Sacramento, CaliforniaAges 18 years+ - NCT05227326RecruitingPhase 1
A new drug for solid cancers that did not respond to usual care
This early-stage (Phase 1) trial tests AOH1996 in adults with solid tumors that have stopped responding to standard treatments. It’s meant to find a safe dose and see if the drug can help, especially in cancers with limited options.
Long Beach, CaliforniaAges 18 years+ - NCT05006482RecruitingPhase 3
Geriatric education and care support for older cancer survivors
This study tests whether a structured health education and “older adult care” approach—done with your oncology team—can improve support for people after cancer. It includes older cancer survivors and a chosen caregiver, using in-person or video visits for follow-up.
Fremont, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Santa Monica, CaliforniaAges 18 years+ - 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.
Stanford, CaliforniaAges 18 years+ - NCT04871542Recruiting
Predicting risk of immune therapy side effects
This study tries to predict who is more likely to get serious side effects from immune checkpoint medicines used for solid tumors. You may help researchers by answering questionnaires before treatment and during follow-up, and by possibly storing sample specimens.
Pasadena, CaliforniaAges 18 years+ - NCT04864054RecruitingPhase 1/Phase 2
Study T-cell therapy for advanced liver cancer
This trial tests a custom immune-cell treatment made to target a marker (GPC3) found on some liver cancers. It’s for adults with advanced HCC whose cancer has worsened after standard treatment or who couldn’t tolerate it.
Duarte, CaliforniaAges 18 years+ - NCT04868604RecruitingPhase 1/Phase 2
Copper PSMA scan and treatment for prostate cancer in men on low testosterone
This trial tests a PSMA-targeted copper medicine used after a special PSMA PET/CT scan to find and treat prostate cancer that has spread. It’s for men whose testosterone is already very low and whose cancer is growing despite hormone-blocking medicines like enzalutamide or abiraterone.
Stanford, CaliforniaAges 18 years+ - NCT04907643Recruiting
Virtual reality program to reduce stomach-cancer pain
This trial tests whether virtual reality (VR) can improve pain and other day-to-day symptoms in people with certain gastrointestinal cancers. You’d use VR for pain relief while researchers measure how you’re feeling.
Los Angeles, CaliforniaAges 18–99 - NCT04771130RecruitingPhase 1/Phase 2
Study of BGB-11417 for blood cancers
This early-phase study tests BGB-11417 in people with certain bone-marrow (blood) cancers such as AML, MDS, or MDS/MPN. The goal is to find out how the medicine works and whether it can control the cancer.

What taking part in a neoplasms 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.
