Understanding CAR T-cell therapy persistence in young patients with ALL
This study looks at why CAR T-cell therapy stops working in some children and young adults with leukemia. It aims to help doctors understand how to make this treatment last longer.
LondonAges Up to 25 years - NCT05800405RecruitingEarly Phase 1
Radiation before CAR T therapy for large B-cell lymphoma
This early-phase study tests whether giving targeted radiation first can improve outcomes when you later receive CAR T-cell therapy for large B-cell lymphoma that has come back or is not responding to treatment. It may help shrink or control lymphoma spots before CAR T is infused.
Duarte, CaliforniaAges 18 years+ - NCT05805605RecruitingPhase 2
Low-intensity stem cell transplant with donor cells and blood-protection
This Phase 2 study tests a low-intensity bone marrow/stem cell transplant using a matched donor plus two medicines to help prevent the donor cells from attacking you. It aims to treat certain blood cancers—especially when standard treatment has not fully worked or when you are in remission but at higher risk.
Minneapolis, MinnesotaAges Up to 75 years - NCT05800210RecruitingPhase 2
T cell and B cell immune “wipeout” after stem cell transplant
This Phase 2 trial studies whether removing certain immune cells (alpha/beta T cells and CD19+ B cells) around the time of a stem cell transplant can improve outcomes for people with high-risk blood cancers. It may help by reducing the immune responses that can interfere with the transplant working, while keeping the process safe.
Gainesville, FloridaAges 6 months–39 years - NCT05786040RecruitingPhase 2
Tafasitamab plus rituximab for PTLD after solid organ transplant
This trial studies tafasitamab plus rituximab to treat a type of lymphoma called post-transplant lymphoproliferative disorder (PTLD) in adults after a solid organ transplant. It’s aimed at helping stop the PTLD when it can be measured and before you’ve had PTLD treatment beyond limited measures like steroid or reducing anti-rejection drugs.
New Brunswick, New JerseyAges 18 years+ - NCT05782335Recruiting
Study immune cell changes with Orencia in rheumatoid arthritis
This trial studies how Orencia (abatacept) affects your immune system’s T and B cells in people with rheumatoid arthritis. It may help researchers better understand who responds to Orencia and what immune changes happen over time.
New York, New YorkAges 18 years+ - NCT05787795Recruiting
Studying early risk signs for multiple sclerosis
This study looks at people who are at higher risk for multiple sclerosis (MS), to better understand early changes before MS is diagnosed. It may help doctors identify who is more likely to develop MS and how to monitor them sooner.
North Haven, ConnecticutAges 18 years+ - NCT05810480Recruiting
Predicting steroid-dependent liver injury with blood test
This study looks at whether a specific blood marker can predict which patients with liver inflammation will need long-term steroid treatment. It may help doctors decide the best treatment for you if you have unexplained liver injury.
AachenAges Any age - NCT05800366RecruitingPhase 2
Testing glofitamab plus polatuzumab for high-risk diffuse lymphoma
This Phase 2 study tests two medicines—glofitamab and polatuzumab—together with chemotherapy to treat newly diagnosed, high-risk diffuse large B-cell lymphoma (DLBCL) that has the CD20 marker. It aims to improve how well the lymphoma responds and how long responses last.
Miami, FloridaAges 18 years+ - NCT05794880Recruiting
Immunotherapy lowering immune cells before transplant in children
This trial tests a special immune-cell “preparation” treatment (called T-cell and B-cell depletion) with adjusted anti-thymocyte globulin (ATG) dosing before a stem cell transplant. It aims to reduce immune-related transplant complications in people under 25 with certain blood cancers in a specific remission status.
Milwaukee, WisconsinAges birth–25 years - NCT05801913RecruitingPhase 1
Personalized immune cell therapy plus a CMV vaccine
This Phase 1 study tests genetically modified immune cells (made from your own blood) plus a vaccine aimed at controlling CMV-related lymphoma. It’s for adults with intermediate or high-grade B-cell non-Hodgkin lymphoma who can’t get (or don’t want) certain standard stem-cell transplant options.
Duarte, CaliforniaAges 18 years+ - NCT05801978RecruitingPhase 4
How long a vaccine’s immune response lasts in adults
This study checks how long your body’s protection signals last after a vaccine. It may help researchers understand which vaccines give longer-lasting immune responses and who may need boosters.
Atlanta, GeorgiaAges 18–50 - NCT05787574RecruitingPhase 2
Reducing inflammation before stem cell transplant in immune disorders
This Phase 2 study tests medicines that calm inflammation before the first stem cell transplant. It aims to make transplant safer and more effective for people with certain inherited immune regulation or inflammatory conditions.
San Francisco, CaliforniaAges Any age - NCT05799768Enrolling by invitation
Ketogenic diet for rheumatoid arthritis symptoms and inflammation
This study tests whether a very low-carbohydrate, ketogenic diet can improve rheumatoid arthritis (RA). It’s designed for people whose RA treatment is already stable and who are not currently using a keto diet or certain medicines.
Oklahoma City, OklahomaAges 18–65 - NCT05805839Enrolling by invitationPhase 2
Study uses brain scans to understand demyelinating diseases
This trial compares scan results in people with multiple sclerosis or related demyelinating conditions versus people without inflammatory demyelinating diseases. The goal is to better understand what’s happening in the brain and how sex differences may play a role.
Rochester, MinnesotaAges 18 years+ - NCT05789303RecruitingPhase 2
Belantamab plus other medicines for relapsed multiple myeloma
This Phase 2 study tests whether belantamab mafodotin combined with carfilzomib, pomalidomide, and dexamethasone can better treat multiple myeloma that has come back. It may help people who have already tried other myeloma treatments but whose cancer has progressed again.
Chicago, IllinoisAges 18 years+ - NCT05783609RecruitingPhase 2
Epcoritamab and rituximab for untreated follicular lymphoma
This phase 2 trial tests whether a combination of epcoritamab plus rituximab can work as a first treatment for follicular lymphoma. It may help people whose lymphoma is causing symptoms or affecting organs, or who have bulky disease, by targeting the lymphoma cells.
Boston, MassachusettsAges 18 years+ - NCT05799378RecruitingPhase 3
Stopping hydroxychloroquine in older adults with stable lupus
This study looks at whether it is safe for people aged 55 and older with long-standing, stable lupus to stop taking hydroxychloroquine (a medicine that helps control lupus) without their disease flaring up. If you have been taking this medicine for at least 7 years and your lupus has been quiet for a while, you may be able to join.
