Recruiting studies in California
- NCT07573111RecruitingPhase 1
QUAIL-100 for Children With Blood Cancers After Stem Cell Transplant
This study tests a new experimental treatment called QUAIL-100 in children and young adults who have had a stem cell transplant for a serious blood cancer. The treatment is designed to help the immune system fight remaining cancer cells.
Palo Alto, CaliforniaAges 1.5 years–39 years - NCT05861050RecruitingPhase 1/Phase 2
Study of 4-drug treatment for newly diagnosed high-risk mantle cell lymphoma
This trial tests a combination of medicines to treat newly diagnosed high-risk mantle cell lymphoma (MCL). It may help shrink the lymphoma and improve outcomes, especially for people whose disease has higher-risk features.
Duarte, CaliforniaAges 18–80 - NCT07250646RecruitingPhase 1
Rebecsinib for secondary AML or high-risk myelofibrosis
This trial tests a new drug called rebecsinib for people with a certain type of leukemia (secondary acute myeloid leukemia) or a high-risk bone marrow disorder (myelofibrosis) that has come back or not responded to other treatments. The goal is to see if it works and is safe.
Duarte, CaliforniaAges 18 years+ - NCT03959085RecruitingPhase 3
Inotuzumab plus chemotherapy for high-risk childhood leukemia
This Phase 3 trial tests whether adding inotuzumab to standard post-induction chemotherapy improves outcomes for children and young teens with high-risk B-ALL, mixed phenotype acute leukemia (MPAL), or certain high-risk B-LLy. It may help by targeting leukemia cells more directly, but participation depends on specific age, lab results, and medical history rules.
Downey, CaliforniaAges 12 months–25 years - NCT03113643RecruitingPhase 1
SL-401 with standard drugs for hard-to-treat blood cancers
This Phase 1 study tests SL-401, given with azacitidine and sometimes venetoclax, to treat acute myeloid leukemia (AML), high-risk myelodysplastic syndrome (MDS), or blastic plasmacytoid dendritic cell neoplasm (BPDCN). It aims to find a safe dose and see whether the combination can improve blood cancer control.
Duarte, CaliforniaAges 18 years+ - NCT04031677RecruitingPhase 3
Surgery with or without chemotherapy for high-risk retroperitoneal sarcoma
This trial studies whether adding chemotherapy before surgery helps people with high-risk retroperitoneal (abdominal-area) leiomyosarcoma or liposarcoma. The goal is to improve outcomes while comparing surgery alone versus surgery plus neoadjuvant chemotherapy.
Irvine, CaliforniaAges 18 years+ - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - 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.
Emeryville, CaliforniaAges 18 years+ - NCT05794958RecruitingPhase 1
Safety of second CAR-T re-infusion for hard-to-treat lymphoma
This Phase 1 study tests whether a second re-infusion of axicabtagene ciloleucel (CAR-T) is safe in people with aggressive B-cell non-Hodgkin lymphoma that came back or did not respond after standard second-line CAR-T. It may help some patients by trying to improve disease control while carefully monitoring side effects.
Palo Alto, CaliforniaAges 18 years+ - NCT05806515RecruitingPhase 2
Carboplatin before surgery for high-risk BRCA prostate cancer
This trial tests giving the chemotherapy drug carboplatin before surgery to treat people with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene change. The goal is to shrink or control the cancer before an operation and improve outcomes.
Irvine, CaliforniaAges 18 years+ - NCT06440850RecruitingPhase 2
Targeted therapy for high-risk BRAF-mutated thyroid cancer
This trial tests two targeted drugs, vemurafenib and cobimetinib, for people with high-risk thyroid cancer that has a specific BRAF V600E mutation. The goal is to see if this combination can help prevent the cancer from coming back after surgery or other initial treatments.
Duarte, CaliforniaAges 18 years+ - NCT06624475RecruitingPhase 2
New immunotherapy before surgery for high-risk basal cell cancer
This trial tests if giving a combination of two immunotherapy drugs (nivolumab and relatlimab) before surgery works better than one drug alone for people with large or high-risk basal cell skin cancer that needs surgery. The goal is to shrink the cancer and make surgery easier.
Irvine, CaliforniaAges 18 years+ - NCT06682728RecruitingPhase 2
Treating high-risk bladder cancer after surgery
This trial tests a combination of two drugs (sacituzumab govitecan and nivolumab) given after surgery to prevent the return of muscle-invasive bladder cancer. It is for patients whose cancer has a high chance of coming back despite surgery.
Orange, CaliforniaAges 18 years+ - NCT05941520RecruitingPhase 2
Acolbifene vs low-dose tamoxifen to prevent breast cancer
This Phase 2 trial compares acolbifene and low-dose tamoxifen to see which better lowers breast cancer risk in premenopausal women at high risk. You would be followed with health visits, blood tests, and a breast tissue sampling procedure.
Duarte, CaliforniaAges 35 years+ - NCT06735690RecruitingEarly Phase 1
Immune cells plus vaccine after stem cell transplant for leukemia
This trial is for people with high-risk acute lymphoblastic leukemia who are getting a stem cell transplant from a family donor. After transplant, you'd receive a treatment that combines specially designed immune cells (CAR T cells) that target your leukemia, plus a vaccine that helps those cells work better.
Duarte, CaliforniaAges 18 years+ - NCT06918431RecruitingPhase 2
Erwinia asparaginase with chemo for new ALL or LBL
This trial tests adding an asparaginase drug to standard chemotherapy for adults with newly diagnosed acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL). The goal is to see if this combination improves outcomes.
Irvine, CaliforniaAges 18–54 - NCT06990542RecruitingPhase 2
Focused radiation therapy for intermediate and high-risk prostate cancer
This trial tests a more precise radiation therapy that targets tumors seen on MRI or special scans, aiming to treat prostate cancer while reducing side effects. It is for men who have not had prostate surgery or previous radiation to the area.
La Jolla, CaliforniaAges 18 years+ - NCT06994676RecruitingPhase 1
Study of CBX-250 for advanced myeloid leukemias
This study tests an experimental drug, CBX-250, for people with certain advanced blood cancers (like AML) that have not responded to standard treatments or have returned. The drug works only for people who have a specific genetic marker (HLA-A*02:01). The goal is to see if it is safe and how well it works.
Palo Alto, CaliforniaAges 12 years+ - NCT04836390Enrolling by invitationPhase 2
Donor immune cell treatment after transplant for high-risk AML
This trial tests an additional immune therapy made from donor natural killer (NK) cells given around the time of a special stem cell transplant for children and young adults with high-risk acute myeloid leukemia (AML). It aims to help prevent the leukemia from coming back or not responding after transplant.
Los Angeles, CaliforniaAges birth–25 years - NCT06533098RecruitingPhase 3
Nipocalimab vs IVIG for FNAIT in pregnancy
This study tests a new medicine called nipocalimab compared to standard IVIG treatment for pregnant women who are at risk of a serious condition where the mother's antibodies attack the baby's platelets (FNAIT). The goal is to see if nipocalimab can prevent complications like bleeding in the baby.
Sacramento, CaliforniaAges 18–45 - NCT07725250Recruiting
AI-guided blood pressure trial for stage I-II hypertension

What taking part in a pregnancy, high risk 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.
