Recruiting studies in California
- 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 - NCT05204459Recruiting
MRI and eye-scan study for MS and related conditions
This trial uses brain MRI and eye imaging tests to study research markers in people with multiple sclerosis (MS) and related neurologic conditions. It may help researchers better understand these diseases and how they change over time.
Los Angeles, CaliforniaAges 18 years+ - NCT05272384RecruitingPhase 1
Testing nivolumab plus ASTX727 for hard-to-treat lymphoma
This Phase 1 study tests whether adding ASTX727 to nivolumab can shrink relapsed or refractory B-cell lymphomas that have come back or did not respond to treatment. It also aims to find a safe dosing plan and see early signs of benefit in certain lymphoma types.
Duarte, CaliforniaAges 18 years+ - NCT06138132RecruitingPhase 1
CAR-T cell therapy for progressive multiple sclerosis
This trial is testing a type of immunotherapy called CAR-T cells (made from your own immune cells) to see if it can help slow or stop progressive multiple sclerosis. It is a very early safety study, so only people with progressive MS who meet strict health criteria can join.
Palo Alto, CaliforniaAges 18–65 - NCT06453044RecruitingPhase 2
Study of two drugs for follicular lymphoma that came back
This study tests a combination of two targeted drugs (mosunetuzumab and polatuzumab vedotin) for people with follicular lymphoma that has come back or not responded to previous treatment. The goal is to see if this two-drug approach can help shrink tumors and control the disease.
Irvine, CaliforniaAges 18 years+ - NCT07042438RecruitingPhase 2
Fecal transplant to improve CAR T therapy for lymphoma
This study tests whether a fecal transplant (transferring healthy gut bacteria) can improve outcomes for people with certain lymphomas who have taken strong antibiotics and are about to get CAR T-cell therapy (Yescarta). The goal is to see if rebuilding gut bacteria helps the treatment work better.
Duarte, CaliforniaAges 18 years+ - NCT05292664RecruitingPhase 1
Venetoclax trial for high-risk blood cancers in young patients
This Phase 1 study tests venetoclax to treat certain high-risk blood cancers in children, teens, or young adults. It is designed to see if the drug can work safely for patients whose disease has returned or did not respond to prior treatment.
San Francisco, CaliforniaAges 1–40 - NCT06854159RecruitingPhase 2
Odronextamab for diffuse large B-cell lymphoma before and after CAR T therapy
This trial tests a drug called odronextamab for people with diffuse large B-cell lymphoma that has come back or not responded to at least two prior treatments. It aims to see if the drug can help before and after a type of immunotherapy called CAR T-cell therapy.
Sacramento, CaliforniaAges 18 years+ - NCT07061951RecruitingPhase 2
Mirdametinib for relapsed or refractory CLL or SLL
This trial tests a drug called mirdametinib for people with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has come back or not responded to at least two prior treatments, including a BTK inhibitor and a BCL2 inhibitor. The goal is to see if mirdametinib can help shrink the cancer or slow its growth.
Duarte, CaliforniaAges 18 years+ - NCT06675123RecruitingPhase 1
Pacritinib with a BTK inhibitor for mantle cell lymphoma
This trial tests a new combination of two targeted drugs (pacritinib plus a BTK inhibitor like ibrutinib) for people with mantle cell lymphoma that has come back or stopped responding to treatment. It may help if your current BTK inhibitor is no longer working well.
Duarte, CaliforniaAges 18 years+ - NCT05828069RecruitingPhase 2
Tovorafenib for young people with worsening Langerhans cell histiocytosis
This Phase 2 trial tests tovorafenib (DAY101) to treat children and young people whose Langerhans cell histiocytosis (LCH) is getting worse, came back, or did not respond to prior treatment. It may help by targeting certain gene changes found in the LCH.
Downey, CaliforniaAges 6 months–22 years - NCT05052528RecruitingPhase 1
CAR T cell therapy for relapsed or refractory large B-cell lymphoma
This trial tests whether adding a targeted antibody (rituximab) before CAR T cell therapy improves outcomes for patients with diffuse large B-cell lymphoma that has come back or not responded to at least two prior treatments.
Sacramento, CaliforniaAges 18 years+ - NCT07133997RecruitingPhase 1
Combination therapy for relapsed CD19+ B-cell leukemia

Duarte, CaliforniaAges 12–55 - NCT04484012RecruitingPhase 2
CAR T cells plus acalabrutinib for mantle cell lymphoma
This trial tests whether modified immune cells (CD19 CAR T cells) given with the medicine acalabrutinib can help people with mantle cell lymphoma that has come back or did not respond. It may help by attacking lymphoma cells more strongly and improving disease control after prior treatment.
Duarte, CaliforniaAges 18–75 - NCT04545762RecruitingPhase 1
Anti-CD19 CAR-T for certain relapsed lymphoma
This Phase 1 study tests an anti-CD19 CAR-T cell treatment in adults with specific types of relapsed or treatment-resistant non-Hodgkin lymphoma. It may help by finding and attacking lymphoma cells that carry the CD19 marker, but it’s early-stage and eligibility is strict.
San Francisco, CaliforniaAges 18 years+ - NCT04871607RecruitingPhase 2
Yttrium antibody plus chemotherapy for hard-to-treat Hodgkin lymphoma
This trial studies a targeted antibody therapy with yttrium, combined with intensive chemotherapy, for adults whose Hodgkin lymphoma did not respond well or came back. It may help by delivering cancer-killing radiation directly to lymphoma cells and preparing the body for treatment after transplant conditioning.

What taking part in a relapsed or refractory multiple myeloma 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.
