Zanubrutinib treatment in several blood cancers
This non-interventional study looks at outcomes for people with certain slow-growing blood cancers who are treated with zanubrutinib, with specific add-on use of obinutuzumab for follicular lymphoma. It may help doctors understand how this treatment is working in real-world care across several cancer types.

CAR T-cell treatment for CD19-positive relapsed leukemia in children
This Phase 2 trial tests pCAR-19B, a customized immune-cell treatment for children and teens with CD19-positive B-ALL that has come back or did not respond to standard therapy. If eligible, you would receive the cell infusion after cell collection and testing to make sure the leukemia cells have the right marker.
Beijing, Beijing MunicipalityAges 3–21 - NCT05332054Enrolling by invitation
Long-term follow-up after prior Caribou treatment
This study checks your health over time after you previously took a Caribou medicine (or got it through a special access program). It helps researchers learn what happens in the longer run after the treatment.

Nipocalimab for adults with chronic inflammatory CIDP nerve disease
This trial tests nipocalimab (an antibody medicine) to improve symptoms and control activity in chronic inflammatory demyelinating polyneuropathy (CIDP), a nerve disease that causes weakness and numbness. It may help reduce disease activity and disability, while checking safety.
Centennial, ColoradoAges 18 years+ - NCT05344469Recruiting
Testing new MS medicines in people with active relapsing MS
This study tests different approved “disease-modifying” MS medicines (shots and pills) in adults with relapsing multiple sclerosis that is currently active. It mainly looks at outcomes based on how newly starting—or recently started—treatments are handled for people with recent relapses and mild disability.
Albstadt, Baden-WurttembergAges 18–100 - NCT05355051RecruitingPhase 2
Azacitidine plus pembrolizumab for Hodgkin lymphoma after relapse
This Phase 2 study tests azacitidine together with pembrolizumab in people whose Hodgkin lymphoma has come back or did not respond (relapsed/refractory). It aims to see whether this combination can control cancer and improve outcomes, especially when standard high-dose chemotherapy is not an option.
Houston, TexasAges 1 year+ - NCT05313243RecruitingPhase 2
Pembrolizumab plus brentuximab for relapsed T-cell lymphoma
This Phase 2 study tests pembrolizumab together with brentuximab for people whose T-cell non-Hodgkin lymphoma has come back or stopped responding to treatment. It may help shrink the lymphoma and improve long-term control by boosting the immune system and targeting a protein called CD30.
New Haven, ConnecticutAges 18 years+ - NCT05355389Recruiting
Home online rehab to improve thinking and movement in MS
This study tests whether doing cognitive-and-movement rehabilitation at home through telehealth helps people with multiple sclerosis (MS). It likely looks at changes in thinking performance and physical function while also checking safety with brain and electrical tests.
BrusselsAges 18–65 - NCT05361694Recruiting
Study aims to distinguish stable vs worsening early myeloma
This study looks at two different “precursor” conditions that can happen before multiple myeloma: MGUS and smoldering myeloma (SMM). Researchers want to better tell which cases are more likely to progress, using blood/urine tests and sometimes bone marrow tissue.
Miami, FloridaAges 18 years+ - NCT05315726Recruiting
Vibration therapy to reduce stiffness after stroke
This trial studies whether regular muscle vibration can reduce post-stroke muscle stiffness and improve how the brain and nerves adapt. If you’re in the right stage after stroke, it may help improve arm and hand movement.
Chalon-sur-SaôneAges 18 years+ - NCT05334888Recruiting
Study how sex and gut bacteria relate to heart risk
This study follows people over time to understand how sex-related factors and gut bacteria may affect heart and blood-vessel risk. It may help researchers identify who could benefit from earlier prevention, based on personal risk patterns.
BerlinAges 18–50 - NCT05336812RecruitingPhase 2
Acalabrutinib with venetoclax or obinutuzumab for untreated CLL
This Phase 2 trial studies how well acalabrutinib works when combined with either venetoclax or obinutuzumab in people with untreated chronic lymphocytic leukemia (CLL). It aims to improve disease control while checking safety and tolerability.
Columbus, OhioAges 18 years+ - NCT05322850RecruitingPhase 1/Phase 2
