Beijing, Beijing MunicipalityAges 18–75 - NCT02996552Recruiting
Ring repair for mild-to-moderate leaky right valve
This trial looks at whether adding a specific repair to the right valve (called tricuspid annuloplasty) during mitral valve surgery helps people whose right valve leakage is not severe. It compares doing the extra right-valve repair versus doing only the mitral valve repair.
Rozzano, MilanoAges 18 years+ - NCT04467944Recruiting
Lumbar fusion outcomes with arthritis in nearby spine segments
This study looks at how well lumbar fusion surgery works long-term when the joint just above or below (adjacent segment) already shows wear-and-tear. It may help predict who benefits most and guide treatment planning.
Beijing, Beijing MunicipalityAges 18–80 - 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 - NCT04504006Recruiting
Tracking surgery choices for lymph node spread in endometrial cancer
This is an observational study that follows people with endometrial cancer who have had surgery to check and remove pelvic (and sometimes paraaortic) lymph nodes. It looks at how different surgical approaches and any added treatment affect local control (keeping cancer from coming back in the pelvis/nearby areas).
Essen, North Rhine-WestphaliaAges 18 years+ - NCT04528979Recruiting
Tests a bioceramic filling material for root-canal treatment outcomes
This study looks at how well a bioceramic sealing material works for tooth root-canal treatment, including cases where previous treatment did not work. If you have certain types of tooth nerve inflammation or infection, you may be eligible to help compare outcomes and improve care.
Sant Cugat del Vallès, BarcelonaAges 18–75 - NCT04527705Recruiting
Testing endodontic retreatment in one versus two visits
This study compares doing tooth root-canal retreatment in one visit versus two visits. It’s meant to see which approach leads to better outcomes for teeth with infection at the root tip (apical periodontitis).
Sant Cugat del Vallès, BarcelonaAges 18–75 - NCT04360200Recruiting
Study of thinking changes in older adults
This trial looks at people over age 50 who have mild thinking or memory problems but do not have dementia by standard clinical criteria. It tests how these early changes are characterized and measured using exams such as blood tests and brain scans, which may help improve understanding and future care.
Guangzhou, GuangdongAges 50 years+ - NCT04469387Recruiting
Reduce adjacent back pain after lumbar surgery
This trial looks at whether a limited decompression (a careful nerve-space “freeing” procedure) can help prevent future problems in the spinal level next to your planned surgery. It targets people with spinal canal narrowing next to the surgery level but who do not yet have symptoms there.
Beijing, Beijing MunicipalityAges 18–80 - NCT03331302RecruitingPhase 1/Phase 2
Tested lung imaging scans in stable COPD patients
This study compares two ways of seeing how well your lungs work: a special MRI scan and another scan that uses a different gas. It may help researchers find which imaging test best reflects lung function in people with COPD.
Charlottesville, VirginiaAges 18 years+ - NCT04599621Recruiting
Testing treatment for heart pain with anxiety or depression
This trial looks at people who have coronary artery disease and unstable or certain stable chest-pain symptoms, especially when anxiety or depressive symptoms are also present. The goal is to see how the study approach helps heart symptoms when mental health symptoms occur at the same time.
SamarkandAges Any age - NCT04454177Recruiting
Smartwatch help to discharge earlier after valve replacement
This study tests whether using a smartwatch can safely help people leave the hospital earlier after a transcatheter aortic valve replacement (TAVR). It checks comfort, safety, and follow-up at home.
Hangzhou, ZhejiangAges 18 years+ - NCT04026360Recruiting
Study early lung, virus, and gut changes in children with cystic fibrosis
This study looks at how a child’s early lung function, viral infections, and gut (microbiome) changes affect cystic fibrosis over time. It may help doctors understand what predicts how lung disease develops, which could improve future care.
BernAges birth–18 years - NCT04679584Recruiting
Study of long-term effects after COVID-19 infection
This study looks at how COVID-19 can affect health and quality of life over the long term. It may help researchers understand symptoms that can last and what changes people experience after recovery.
Würzburg, BavariaAges 18 years+ - NCT03938155Recruiting
