- NCT04990908Recruiting
Screening children in ICU for immune problems after severe infection
This study checks children in pediatric intensive care for possible “immune system problems” after a severe infection. The goal is to find primary immunodeficiencies early, which may change follow-up and treatment for the child’s immune health.
MontpellierAges 3 months–16 years - NCT04991103RecruitingPhase 2
Testing delaying stem cell transplant after early myeloma response
This Phase 2 study tests whether people with newly diagnosed multiple myeloma can safely delay or avoid an immediate stem cell transplant if they respond well to early treatment. It aims to see if this “response-adapted” approach can still control the disease while reducing the need for upfront transplant for some patients.
Birmingham, AlabamaAges 18 years+ - NCT04993690RecruitingPhase 1
Oral LP-168 for relapsed or hard-to-treat B-cell lymphoma
This Phase 1 study tests whether an oral medicine called LP-168 can be given safely and possibly work against lymphoma that has come back or is not responding to standard treatment. It’s mainly looking for safety, but your results could help determine whether the drug should be studied further.
Beijing, Beijing MunicipalityAges 18–80 - NCT04993885RecruitingPhase 2
Avatrombopag for adults with immune low platelets
This trial studies avatrombopag to raise platelet counts in adults with immune thrombocytopenia (ITP) caused by autoimmune conditions. It may help reduce bleeding risk when platelet levels are very low.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT04996875RecruitingPhase 2
Bezuclastinib for advanced mast cell disease
This Phase 2 study tests bezuclastinib, a targeted medicine, in people with advanced systemic mastocytosis (including certain advanced forms with blood cancers). It aims to shrink measurable disease and improve symptoms, while helping people who may also need treatment for an associated blood cancer.
Birmingham, AlabamaAges 18 years+ - NCT04998669RecruitingPhase 2
Loncastuximab plus rituximab for relapsed follicular lymphoma
This Phase 2 study tests whether loncastuximab, combined with rituximab, can shrink and control follicular lymphoma that has come back or not responded to prior treatment. It may help people who still have active disease that needs treatment and meet specific scan and blood test requirements.
Fort Myers, FloridaAges 18 years+ - NCT05001087Recruiting
Patient and doctor registry for active multiple myeloma
This study creates a real-world registry (a group database) of people with active, symptomatic multiple myeloma. It helps researchers learn from patients and doctors over time and may support future research and treatment improvements.
Florence, FirenzeAges 18 years+ - NCT05002023Recruiting
Study tracking health and immunity from pregnancy to your child
This study follows healthy pregnant people during pregnancy and then checks children’s health and immune system development. You may be able to join if you’re an adult with a single, healthy pregnancy and you can consent.
HamburgAges 18–50 - NCT05003388RecruitingPhase 1
Safety study of IV stem cells from donor umbilical cord
This early study tests whether an IV infusion of donor-derived stem cells is safe for people with multiple sclerosis. It mainly focuses on side effects and safety, not whether it improves MS symptoms yet.
St John'sAges Any age - NCT05003310Recruiting
Splenic stimulation study for active rheumatoid arthritis
This study tests a treatment that stimulates the spleen to help calm symptoms of active rheumatoid arthritis (RA). It’s mainly for people whose RA has not improved enough after several newer arthritis medicines.
Anniston, AlabamaAges 22–75 - NCT05003986RecruitingPhase 2
Sparsentan for children with protein leaking kidney diseases
This Phase 2 study tests sparsentan in children with certain kidney diseases that cause high amounts of protein in the urine. It aims to see if the medicine can reduce kidney damage signals and protein leakage compared with standard care.
Los Angeles, CaliforniaAges 1–17 - NCT05003934RecruitingPhase 1
IV stem cell treatment safety study for rheumatoid arthritis
This Phase 1 trial tests how safe an intravenous (through a vein) stem cell product is for people with rheumatoid arthritis. It is mainly looking for side effects and safety rather than proving it works yet.
St John'sAges Any age - NCT05004493Recruiting
Plasma exchange patient registry and sample collection
This study collects information and blood or other samples from people who are getting plasma exchange therapy. The goal is to build a registry (a organized database) that researchers can use to better understand and improve care.
Iowa City, IowaAges 12–99 - NCT05006482RecruitingPhase 3
Geriatric education and care support for older cancer survivors
This study tests whether a structured health education and “older adult care” approach—done with your oncology team—can improve support for people after cancer. It includes older cancer survivors and a chosen caregiver, using in-person or video visits for follow-up.
Tuscaloosa, AlabamaAges 18 years+ - NCT05007340Recruiting
ILD and autoimmune conditions registry and sample storage
This study collects health information and may store blood or other samples to learn more about interstitial lung disease (ILD) and autoimmune-related conditions. Joining could help researchers understand different causes of ILD and improve future care.
Montreal, QuebecAges 18 years+ - NCT05009758Recruiting
Asthma and nasal polyps study to match immune patterns
This study looks at different “immune inflammation patterns” in people with asthma and/or nasal polyps. It may help researchers better tailor future treatments by figuring out which patterns go with which symptoms.
ViennaAges 18–99 - NCT05010005RecruitingPhase 1
Testing ruxolitinib plus duvelisib for relapsed T-cell lymphoma
This Phase 1 study tests how safe and effective ruxolitinib plus duvelisib are in adults with certain types of mature T-cell lymphomas. You may be considered if your lymphoma has come back or worsened despite prior treatment, and the study checks whether this pill combination can help control the disease.
Miami, FloridaAges 18 years+ - NCT05010564RecruitingPhase 1
TRICAR-ALL CAR-T treatment for tough childhood leukemia
This Phase 1 trial tests a customized CAR-T cell therapy for children and young adults with B-cell acute lymphoblastic leukemia (B-ALL) that keeps coming back or doesn’t respond to treatment. It aims to find a safer and effective way to control leukemia by targeting specific markers on the leukemia cells.
Houston, TexasAges 1–25 - NCT05010902Recruiting
Pregnancy and MS study for people 18 and older
This study follows people with multiple sclerosis (MS) or a related condition to learn how pregnancy affects MS. You may be asked to complete health questionnaires and get MRI scans, which can help researchers understand what changes during pregnancy.
BerlinAges 18–50 - NCT05011045Recruiting

Study how high-dose steroids move through the body
This study measures blood levels of high-dose steroid medicines (prednisolone or related steroids) to understand how the body processes them in different real-life situations. It may help improve how steroids are dosed and monitored for people needing short-term or longer-term anti-inflammatory treatment.
LondonAges 18–75 - NCT05014165Recruiting
