Leflunomide plus steroids for acute graft-versus-host disease
This early-phase trial tests whether adding leflunomide to standard steroid treatment can better control acute graft-versus-host disease (aGvHD) after a stem cell transplant. It may help reduce the immune reaction that damages the body while keeping treatment safe and manageable.
Duarte, CaliforniaAges 18 years+ - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 years+ - NCT05443321Enrolling by invitation
Health information sharing during hospital transfers
This trial studies whether sharing patients’ health information between hospitals during transfers can improve outcomes. You may be included if you are moved from a specific partner hospital to Brigham and Women’s Hospital and admitted to certain hospital units.
Boston, MassachusettsAges 18 years+ - NCT05444920Recruiting
Web network for people with amyloidosis in Italy
This trial builds an Italian online network to learn from people who may have amyloidosis (an abnormal protein condition). It collects information from participating centers and could help doctors better understand different types of amyloidosis.
Legnano, MIAges 18–99 - NCT05445583Recruiting
Technology support program for young adults with uncontrolled asthma
This study tests whether a technology-based program can help improve asthma control in young African American adults who are not currently well controlled. It may help you track symptoms and use asthma tools more consistently between clinic visits.
Tallahassee, FloridaAges 18–30 - NCT05452564RecruitingPhase 2
Baricitinib to help reduce HIV in the brain
This Phase 2 study tests baricitinib to see if it can lower HIV activity in the brain (CNS) for people already on stable HIV treatment. If you have well-controlled HIV in your blood, this trial looks for additional benefit inside the nervous system.
Atlanta, GeorgiaAges 18–65 - NCT05421416RecruitingPhase 2
Loratadine to prevent bone pain after stem cell transplant treatment
This trial tests loratadine (an allergy medicine) to see if it can prevent bone pain caused by a growth-factor injection used during lymphoma or multiple myeloma treatment. It may help reduce pain around the time you get that injection and your upcoming stem cell transplant.
Edmonton, AlbertaAges 18 years+ - NCT05444946Recruiting
Itraconazole alone versus with steroid pills for Aspergillus lung overlap
This trial compares itraconazole taken by mouth alone versus itraconazole plus steroid pills in people who have a mix of two Aspergillus lung conditions. It aims to see which approach works better to control symptoms and lung changes caused by Aspergillus infection.
Chandigarh, ChandigarhAges 15–90 - NCT05414409RecruitingPhase 2
Gut microbiome study in young people with type 1 diabetes
This Phase 2 study looks at the gut microbiome (the bacteria in your intestines) in youth with type 1 diabetes, and how metformin may work differently through the gut. It may help researchers understand mechanisms and future treatment options.
