Compare immune activity and HIV hidden reservoir on two treatments
This study compares how active the immune system is and how large the “hidden” HIV reservoir is in people on two different HIV treatment types. It may help researchers understand whether staying on a tenofovir-containing regimen leads to better control of HIV hiding in the body.

Combining hydroxychloroquine and dexamethasone for ITP with positive ANA
This trial tests if adding hydroxychloroquine (HCQ) to the steroid dexamethasone (DEX) works better than dexamethasone alone for adults with immune thrombocytopenia (ITP) who have a positive antinuclear antibody (ANA) blood test. The goal is to see if this combination can safely raise platelet counts and reduce bleeding risk.
Shanghai, Shanghai MunicipalityAges 15–75 - NCT06998264Recruiting
Immune response to flu in young children
This study looks at how children's immune systems fight the flu in the nose and throat. It aims to understand why some children get very sick and others don't, which could help create better treatments and vaccines.

Study of guselkumab plus JAK inhibitors for tough-to-treat IBD
This trial tests a combination of two medications—guselkumab and a JAK inhibitor—for people with inflammatory bowel disease that hasn't responded to other treatments. The goal is to see if this combination is safe and effective for patients with hard-to-control Crohn's disease or ulcerative colitis.

Mango study for Hispanic/Latino teens' health
This study looks at whether eating mango every day for 12 weeks can improve gut health and heart health in Hispanic/Latino teens who are overweight. Participants will be asked to eat a mango product and take daily photos.
Davis, CaliforniaAges 12–19 - NCT06037564Enrolling by invitationPhase 4
Switching HIV treatment to a simpler daily pill
This study tests whether switching your current HIV medication to a daily pill with doravirine, dolutegravir, and lamivudine is safe and effective. It is for people whose HIV is well-controlled but who have had to change treatment before because it stopped working.
Aarau, Canton of AargauAges 18 years+ - NCT07333118RecruitingEarly Phase 1
Testing GT801 for severe autoimmune diseases
This trial tests a new treatment called GT801, a type of CAR-T cell therapy, for people with moderate to severe autoimmune diseases that have not responded to standard treatments. It aims to see if GT801 can safely and effectively control the disease.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT05520151Recruiting
Oral immune-support before kidney or bladder surgery
This trial studies whether an oral immune-modulating product given before major bladder or kidney surgery can lower the risk of postoperative complications. If you’re scheduled for surgery like cystectomy or nephrectomy, it may be an option to help your recovery.
Aulnay-sous-BoisAges 18 years+ - NCT06454955RecruitingEarly Phase 1
PET scan imaging study for solid tumors using a new probe
This trial tests a new imaging agent that targets a protein called B7-H3 found on many solid tumors. It uses PET/CT to help doctors see and stage tumors more clearly.
Beijing, Beijing MunicipalityAges 18–75 - NCT07453342Recruiting
Safety of immunotherapy side effects and restarting treatment
This study looks at patients who had side effects from cancer immunotherapy (checkpoint inhibitors). The goal is to understand those side effects and whether it is safe to restart immunotherapy after they resolve.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05912517RecruitingPhase 3
Nipocalimab for high-risk pregnancy blood disease
This Phase 3 trial tests nipocalimab (an antibody medicine) to help prevent severe blood breakdown in a baby when a parent has certain blood antibodies. It enrolls people who previously had severe hemolytic disease in a past pregnancy and who are currently early in pregnancy with the same risk antibodies.
La Jolla, CaliforniaAges 18–45 - NCT07220252RecruitingPhase 2/Phase 3
Ublituximab for children with relapsing multiple sclerosis
This trial tests a new drug called ublituximab to see if it can reduce flare-ups in children and teens who have relapsing multiple sclerosis. It aims to understand if the treatment is safe and effective for younger patients.
GdanskAges 10–17 - NCT07433621RecruitingPhase 1
Quercetin for XIAP deficiency in males ages 2 and up
This trial tests if the supplement quercetin can help patients with XIAP deficiency (an immune condition affecting the body's ability to control cell death and inflammation). It is given as a pill or liquid and might reduce inflammation-related symptoms.
Cincinnati, OhioAges 2 years+ - NCT05825183Recruiting
Ultrasound-guided vacuum procedure study after early pregnancy loss
This trial studies a medicine-product made from conception tissue (from an ultrasound-guided manual vacuum aspiration procedure) for people with an early miscarriage or termination. It may help researchers understand whether this approach is safe and potentially beneficial for recovery, but eligibility depends on specific medical and procedural factors.
