Study of MS relapses after surgery
This study looks at relapses (new or worsening MS symptoms) after surgery in people with multiple sclerosis (MS). It may help researchers understand what triggers relapse after surgery so better care can be planned.
Athens, AtticaAges 18–70 - NCT01703429Recruiting

Registry for idiopathic retroperitoneal fibrosis in China
This study is a registry that collects medical information (and sometimes tissue results) from people with retroperitoneal fibrosis that is not caused by another known condition. It may help doctors better understand the disease and improve future care.
Beijing, Beijing MunicipalityAges 18–75 - NCT03929887Recruiting
Kidney biopsy patients join a kidney tissue research bank
This study builds a kidney tissue “library” to help researchers analyze kidney disease in newer ways. It may help by improving how glomerular (kidney filter) diseases are understood over time, using samples from people who already had a biopsy.
ChuncheonAges Any age - NCT04312854Recruiting

This study follows adults in China who have IRPF (idiopathic retroperitoneal fibrosis). It aims to better understand the condition and may help improve how it’s diagnosed and managed over time.
Beijing, Beijing MunicipalityAges 18–75 - NCT03040583Recruiting
Study of people with primary Sjögren’s syndrome
This study follows adults with primary Sjögren’s syndrome. It may help researchers understand the condition better by using information from people who have already joined the earlier ASSESS study.
Le Kremlin-Bicêtre, Val De MarneAges 18 years+ - NCT04477967Recruiting
Creating a liver transplant biobank for children
This trial sets up a long-term collection of medical information and samples from children who have had a liver transplant. It helps doctors study outcomes over time and improve care for future patients.
Chongqing, Chongqing MunicipalityAges 1 month–18 years - NCT02918188RecruitingPhase 2
Hydrogen therapy for steroid-resistant graft-versus-host disease
This Phase 2 study tests whether hydrogen therapy can improve symptoms in people with chronic graft-versus-host disease (cGVHD) who cannot tolerate steroid treatment. If steroids aren’t working or can’t be used, this trial may offer an alternative approach to help control the illness.
Beijing, Beijing MunicipalityAges Up to 65 years - NCT04500678RecruitingPhase 2/Phase 3
Metformin to improve immune health in HIV
This study tests whether a diabetes drug called metformin can improve the immune system and help keep the HIV virus under control in people who are already doing well on HIV treatment. If you are over 40 and have had a stable viral load for a year, this could be a way to boost your immune health.
Honolulu, HawaiiAges 40 years+ - NCT02836158RecruitingPhase 2/Phase 3
Test drug plus spinal chemotherapy for older PCNSL
This trial studies whether adding R-IDARAM and medication delivered into the spinal fluid can improve treatment for primary central nervous system lymphoma (PCNSL) in newly diagnosed older adults. It may help by targeting lymphoma cells in the brain, covering membranes, and spinal fluid.
Beijing, Beijing MunicipalityAges 60–75 - NCT04538937Recruiting
Study of high eosinophils causing lung/airway damage
This registry study looks at adults with high eosinophils (a type of immune cell) that are believed to be causing damage in the airways or lungs. It aims to better identify these eosinophils and understand what is going on so future treatments can improve.
InnsbruckAges 18 years+ - NCT04532281RecruitingEarly Phase 1
CD19 CAR-T therapy for relapsed or resistant blood cancers
This early-phase study tests a treatment called CD19 CAR-T, made from your immune cells, for people whose CD19+ blood cancer has come back or did not respond. It may help your body better recognize and attack cancer cells, but eligibility is tight and the study is still early.
Hangzhou, ZhejiangAges Any age - NCT04532203RecruitingEarly Phase 1
CAR-T therapy for leukemia or lymphoma in the brain
This early-phase study tests CAR-T cells—immune cells engineered to recognize cancer—for people whose leukemia or lymphoma has spread to the central nervous system (the brain/spinal fluid). It may help shrink or control hard-to-treat (relapsed or refractory) cancers in the brain.
Hangzhou, ZhejiangAges 3–75 - NCT04603872RecruitingEarly Phase 1
CAR-T plus dasatinib for hard-to-treat B-cell cancers
This early study tests a cancer-fighting treatment that uses CAR-T cells together with dasatinib for people whose B-cell cancers have come back or did not respond. It aims to improve control of the cancer in cases that are often resistant to standard treatment.
Hangzhou, ZhejiangAges 18–70 - NCT03875703Recruiting
Biology sample collection after routine vaccination
This study collects biological samples (like blood and/or other samples) after you get a routine vaccine. It helps researchers learn more about how vaccines affect the body.
CréteilAges 18 years+ - NCT04637711Recruiting
Surgery for stubborn granulomatous breast inflammation
This study looks at surgical treatment for granulomatous lobular mastitis that has not been improving with non-surgical care. It may help people with more widespread or complicated breast inflammation, especially when there are abscesses or skin breakdown.
Wuhan, HubeiAges 18–60 - NCT04227015RecruitingEarly Phase 1
Study of a CD19 CAR T-cell treatment for relapsed leukemia
This early-phase trial tests an injected “CAR T” cell therapy made to attack CD19-positive blood cancers that have come back or did not respond. If you qualify, the study checks whether the treatment can help control the cancer and is safe enough to study further.
Hangzhou, ZhejiangAges 3–70 - NCT04675918Recruiting
Registry for children’s in-hospital cardiac arrest
This study collects information about children (from 1 month to 18 years) who have a cardiac arrest while in the hospital. The goal is to better understand what happens during these emergencies and improve care in the future.
MadridAges 1 month–18 years - NCT02537769Recruiting
Surgery to fix a leaky tricuspid valve in LVAD patients
This study looks at whether fixing a mildly leaky tricuspid valve during LVAD surgery improves outcomes for people with advanced heart failure. It’s mainly aimed at patients who are already scheduled to receive an implantable LVAD.
Seattle, WashingtonAges 18 years+ - NCT04526431Recruiting
Tacrolimus dose study in early kidney transplant patients
This study looks at how tacrolimus (a rejection-preventing medicine) should be dosed in the first days to years after a kidney transplant. It may help personalize dosing by comparing different patient groups, including using genetic testing.

Testing intermittent ibrutinib for advanced chronic lymphocytic leukemia
This trial studies whether taking ibrutinib in a less continuous (“intermittent”) schedule can keep your chronic lymphocytic leukemia (CLL) under control. It’s for people who have already received ibrutinib for at least 6 months and had a good early response, aiming to reduce treatment intensity while tracking safety and cancer control.
TrondheimAges 18 years+ - NCT04875819RecruitingPhase 4
