Understanding Immune Causes of Kidney Membrane Disease
This study examines blood and kidney tissue samples from people with membranous nephropathy—a condition where the kidney's filtering membrane is damaged by the immune system. Researchers are trying to understand which immune markers predict how the disease will progress and respond to treatment.

Brain cell activity in mild asthma and allergies
This study looks at brain inflammation in people with mild asthma who are also allergic to common triggers like cats, dust mites, or ragweed. It uses MRI scans to see if a certain brain cell activity is different, which may help us understand asthma better and lead to new treatments.

Mogamulizumab with low-dose skin radiation for lymphoma skin disease
This Phase 2 study tests mogamulizumab together with low-dose total skin electron beam radiation to treat mycosis fungoides or Sézary syndrome, two types of skin lymphoma. It may help shrink skin disease and control symptoms by combining an immune-targeting medicine with skin-focused radiation.
Stanford, CaliforniaAges 18 years+ - NCT04314752Recruiting

CAR-T therapy study for older adults
This study looks at how well CAR-T cell therapy works and how safely it can be given to older adults. It is for people whose cancer or related blood condition has come back or did not respond, and who are receiving a standard (commercial) CAR-T product.

Testing a stronger rituximab dose schedule for new ITP
This trial studies whether a “dose-dense” rituximab schedule can help children and teens with newly diagnosed, high-risk immune thrombocytopenia (ITP). It aims to raise/maintain platelet counts and control bleeding, while carefully checking safety.
Vahalla, New YorkAges 1–21 - NCT04307576RecruitingPhase 3
Study for newly diagnosed ALL children and young adults
This Phase 3 trial studies a treatment plan for people up to age 45 who are newly diagnosed with B-cell or T-cell acute lymphoblastic leukemia (ALL). The goal is to see whether the study treatment improves outcomes compared with standard approaches.
BrusselsAges birth–45 years - NCT04318678RecruitingPhase 1
CD123 CAR T-cell therapy for relapsed leukemia and related cancers
This early-phase study tests a lab-made immune therapy (CD123 CAR T cells) for children and young adults up to age 21 whose cancer has come back or didn’t respond to treatment. The goal is to see if these CAR T cells can find and attack cancer cells that carry a marker called CD123.
Memphis, TennesseeAges Up to 21 years - NCT04262492Recruiting
Registry of adults with APS on blood thinners
This study keeps an international registry of people with antiphospholipid syndrome (APS) who are taking direct oral blood thinners. It may help doctors better understand how APS patients do over time and improve future care, even if you’re not asked to change treatment.
NancyAges Any age - NCT04259359Recruiting
Bee sting allergy trial for people starting venom immunotherapy
This trial studies whether having strong reactions to a specific bee venom protein can make venom immunotherapy less effective. It may help doctors better predict who is at higher risk for therapy failure after bee stings.
GrazAges 18–70 - NCT04373473RecruitingPhase 2
Oral stool treatment to prevent ulcerative colitis flare-ups
This study tests whether taking freeze-dried (lyophilized) donor stool material by mouth can help prevent ulcerative colitis from coming back or causing intestinal inflammation. Participants are in remission and stay on their usual treatment while receiving the study product.
Houston, TexasAges 18 years+ - NCT04330118Recruiting
Study immune cells in DRESS and drug rash reactions
This trial studies how certain immune cells (eosinophils) behave during severe drug reactions like DRESS and during milder drug rashes. It may help doctors understand what drives organ damage and improve how these reactions are managed.
ArrasAges 18 years+ - NCT04373057RecruitingPhase 1/Phase 2
Prebiotic fiber to prevent gut inflammation after transplant
This early-phase study tests a prebiotic (galacto-oligosaccharide) to see if it can lower or prevent gut inflammation caused by acute graft-versus-host disease (acute GVHD) after a stem cell transplant. If you’re scheduled for an allogeneic transplant, participating may help researchers find safer ways to protect your gut.
Kansas City, KansasAges 18–80 - NCT04293042RecruitingEarly Phase 1
BK virus treatment using donor immune cells after transplant
This early-phase study tests whether immune cells made from a donor (T cells) can treat BK virus infection in people whose immune system is weak after a stem cell transplant or chemotherapy. It may help control the virus causing bladder/urinary symptoms.
Philadelphia, PennsylvaniaAges 1 month–25 years - NCT04297592Enrolling by invitationPhase 4
Antibiotics to prevent infection after hip or knee replacement
This trial studies whether giving antibiotics before and/or after surgery can lower the chance of a serious joint infection after elective hip or knee replacement. It’s aimed at people at higher risk for infection.
Iowa City, IowaAges 18–99 - NCT04334707Recruiting
Study kidney damage in people with long-term diabetes
This study is looking at different kidney health patterns in people with diabetes, especially diabetic kidney disease and people who have not developed kidney damage despite long-term diabetes. It may help researchers understand why kidney problems happen—and what protective factors might prevent them.
Tucson, ArizonaAges 18 years+ - NCT04368702Recruiting
MRI-guided radiation for people needing radiation for cancer
This study tests whether radiation given with help from MRI (a type of scan) can better treat cancers that need radiation. You may be eligible if your cancer is confirmed and you can safely have MRI scans.
