Recruiting studies in California
- NCT07225855Recruiting
Support for older adults with head and neck cancer and their caregivers
This trial tests whether a special geriatric assessment (a check-up for older adults) and extra support can help people aged 60+ with head and neck cancer feel better during chemotherapy and radiation. It also looks at how this helps their family or friend caregivers.
Duarte, CaliforniaAges 18 years+ - NCT07400029RecruitingPhase 2
Obecabtagene autoleucel for B-cell ALL in remission
This trial tests a new cell therapy called obecabtagene autoleucel (a 'living drug' made from your own immune cells) for people with a type of blood cancer (B-cell ALL) that has responded to initial treatment but may still have tiny traces. The goal is to see if it can prevent relapse after remission.
Duarte, CaliforniaAges 40 years+ - NCT05335928RecruitingPhase 3
Abatacept for immune-therapy heart inflammation in hospitalized adults
This Phase 3 trial tests abatacept to treat myocarditis (inflammation of the heart muscle) caused by immune checkpoint cancer medicines. It may help patients recover faster and safely manage this serious side effect while they are in the hospital.
Los Angeles, CaliforniaAges 18 years+ - NCT06767514RecruitingPhase 3
Ivonescimab for first-line treatment of advanced NSCLC with high PD-L1
This trial tests a new drug called Ivonescimab as the first treatment for people with advanced (stage IV) non-small cell lung cancer whose tumors have high levels of PD-L1 (a protein that helps cancer hide from the immune system). The goal is to see if it can help shrink or control the cancer.
Alameda, CaliforniaAges 18 years+ - NCT04683250RecruitingPhase 1/Phase 2
RET-targeting drug study for advanced cancers with RET changes
This trial tests an “RET-inhibitor” medicine (TAS0953/HM06) for advanced solid tumors that have RET gene changes. It may help shrink tumors by blocking cancer growth signals from the RET gene.
Orange, CaliforniaAges 18 years+ - NCT06855277RecruitingPhase 3
AAA817 with hormone therapy for advanced prostate cancer
This trial tests a new combination treatment (AAA817 plus a hormone therapy) against standard care for men with advanced PSMA-positive prostate cancer that has spread and stopped responding to a previous hormone therapy. It may be an option if you haven't had certain prior treatments.
Palo Alto, CaliforniaAges 18–100 - NCT05317858RecruitingPhase 3
Open the brain’s blood barrier to treat lung cancer brain spots
This trial tests whether using focused ultrasound to temporarily open the brain’s blood barrier—plus standard immune therapy—can better treat non-small cell lung cancer (NSCLC) that has spread to the brain. It aims to help medicines reach the brain tumor spots more effectively, while still using the usual lung cancer treatment.
Newport Beach, CaliforniaAges 18–100 - NCT07246863RecruitingPhase 2
Testing visugromab and nivolumab with or without docetaxel for advanced lung cancer
This trial tests a new combination of drugs (visugromab, nivolumab, and possibly docetaxel) for people with advanced non-squamous non-small cell lung cancer that worsened after one prior treatment with an immunotherapy. The goal is to see if the combination helps control the cancer better.
Los Angeles, CaliforniaAges 18 years+ - NCT07226154Recruiting
Predicting chemo response in pancreatic cancer
This study looks at blood samples to see if we can predict how well pancreatic cancer responds to chemotherapy before surgery. It aims to help doctors choose the best treatment for each patient.
Duarte, CaliforniaAges 18 years+ - NCT06859801Recruiting
Bone pain study combining ablation and radiation
This study looks at combining two treatments for painful bone tumors that have spread from other cancers. It tests if using both treatments together provides better pain relief than either alone.
San Diego, CaliforniaAges 21 years+ - NCT04566328RecruitingPhase 3
Newly diagnosed multiple myeloma test of combination therapy
This Phase 3 trial tests a combination treatment approach for adults with newly diagnosed multiple myeloma, focusing on response and deeper remission. It may help by improving how well the disease is controlled early and measuring results beyond standard tests.
Arroyo Grande, CaliforniaAges 18 years+ - NCT04949464Recruiting
Smoking quit coaching plus lung scans for people with HIV
This study tests a behavior-change program to help people with HIV quit smoking, along with routine low-dose lung CT scans to find warning signs early. It’s a feasibility study, meaning the main goal is to see if the approach is practical and acceptable, and if people can follow through.
La Jolla, CaliforniaAges 45–80 - NCT05256225RecruitingPhase 3
Adding Herceptin medicines to chemo for HER2-positive endometrial cancer
This Phase 3 trial tests whether adding Herceptin Hylecta or Phesgo to standard chemotherapy works better than chemotherapy alone for HER2-positive serous endometrial cancer or carcinosarcoma. It may help by improving how well treatment controls or shrinks the cancer.
Auburn, CaliforniaAges 18 years+ - NCT03937635RecruitingPhase 3
Lenalidomide and dexamethasone, with or without daratumumab
This phase 3 trial studies whether lenalidomide plus dexamethasone can prevent or delay progression of “high-risk smoldering” multiple myeloma, and whether adding daratumumab improves outcomes. It’s meant for people who are not yet showing symptoms, but whose lab and scan results suggest higher risk.
Arroyo Grande, CaliforniaAges 18 years+ - NCT06971614RecruitingPhase 2
T3011 for bladder cancer not responding to standard treatments
This trial tests a drug called T3011 for a type of bladder cancer that hasn't responded to standard treatments like BCG or chemotherapy. It aims to see if T3011 can help shrink the cancer or keep it from growing, offering a new option for people who have limited choices.
Los Angeles, CaliforniaAges 18 years+ - NCT06764316RecruitingPhase 1
Safety study of BAY 3547926 for advanced liver cancer
This trial tests a new drug called BAY 3547926 for people with advanced liver cancer that cannot be removed with surgery or has not responded to other treatments. The goal is to see if the drug is safe and how well it works.
Duarte, CaliforniaAges 18 years+ - NCT06673017RecruitingPhase 1
Testing a new treatment for pancreatic cancer before surgery
This trial tests a new treatment, PTM-101, placed during a laparoscopy procedure for people with pancreatic cancer that can be removed with surgery. It aims to see if adding this treatment before standard chemotherapy helps improve outcomes.
Newport Beach, CaliforniaAges 18 years+ - NCT07226986RecruitingPhase 1/Phase 2
Study of AMO959 with Lutetium-177 and ARPI for prostate cancer
This trial tests a new combination therapy for men with advanced prostate cancer that has spread and is no longer responding to hormone therapy. It combines an experimental drug (AMO959) with a targeted radiation treatment (Lutetium-177) and a standard hormone therapy to see if it helps control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06064097RecruitingPhase 2
Nivolumab plus chemo for young people with nasopharyngeal cancer
This trial tests combining the immunotherapy drug nivolumab with standard chemotherapy to treat newly diagnosed nasopharyngeal cancer in children and young adults. The goal is to see if adding this immune-boosting medicine can help shrink tumors and prevent the cancer from coming back.
Downey, CaliforniaAges Up to 21 years - NCT07415031RecruitingPhase 2
Long term treatment with adagrasib for solid tumor patients
This trial allows people with solid tumors who are already benefiting from the study drug adagrasib in an earlier Mirati study to continue getting it for the long term. It’s for people whose doctors see ongoing benefit and who still meet the safety rules.
Bellflower, CaliforniaAges 18 years+ - NCT07222800RecruitingPhase 3
Testing a new drug plus chemo for stage 4 colorectal cancer
This study tests a new experimental drug (PF-08634404) combined with standard chemotherapy for people with stage 4 colorectal cancer who have not yet been treated for their advanced disease. The goal is to see if the combination helps shrink or slow the growth of tumors.
Berkeley, CaliforniaAges 18 years+ - NCT06560021Enrolling by invitation
Random biopsies in inflammatory bowel disease surveillance
This trial looks at whether taking random biopsies during a routine colonoscopy is helpful for people with inflammatory bowel disease (IBD) who are at risk for colon cancer. It aims to understand if random biopsies can detect early signs of cancer or pre-cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06577441RecruitingPhase 2
Adding enasidenib to usual care for higher-risk MDS with IDH2 mutation
This trial tests whether adding enasidenib (a targeted pill) to the standard chemotherapy (cedazuridine-decitabine) works better than the chemotherapy alone for people with higher-risk myelodysplastic syndrome (MDS) whose cells have a specific change in the IDH2 gene.
Berkeley, CaliforniaAges 18 years+ - NCT06672146RecruitingPhase 2

What taking part in a 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.
