MaadiAges 16–40 - NCT05255978Recruiting
Follow-up study for hepatitis B with fatty liver
This observational study looks at people with chronic hepatitis B who also have fatty liver (non-alcoholic fatty liver disease). It follows how their liver health changes over time and may help doctors understand outcomes and risk factors.
Wuhan, HubeiAges 18 years+ - NCT03158090Recruiting
Study of treatment patterns for acromegaly over time
This study follows people with acromegaly to better understand how treatments are used in real life and how well they work over time. It may help improve future treatment choices by comparing outcomes across different care patterns.
Guangzhou, GuangdongAges 18–75 - NCT04733404Recruiting
Dragonfly device study for functional mitral valve leakage
This trial tests a catheter-based procedure (putting a small device through blood vessels) to repair a leaking mitral valve caused by heart muscle problems. It aims to reduce symptoms and improve heart function and safety in people who are still having heart failure symptoms despite standard treatment.
Hangzhou, ZhejiangAges 18 years+ - NCT05319483Recruiting
Study of new head and neck cancer patients
This study enrolls adults with a first-time head and neck cancer diagnosis and collects health and treatment information to better understand the disease. It may help clinicians improve care by learning which treatments and patient features matter most.
Pécs, BaranyaAges Any age - NCT05326295Recruiting
Breast cancer study using tumor cells in blood
This trial checks whether a blood test that looks at tumor cells can help guide treatment for people with breast cancer. If you join, your care team will follow your responses over time to see if this “phenotype surveillance” approach is useful.
Changsha, HunanAges 18–75 - NCT03425812Recruiting
NSAID medicines to prevent flares in spondyloarthritis after remission
This trial tests whether taking nonsteroidal anti-inflammatory drugs (NSAIDs) helps people with axial spondyloarthritis stay in remission and avoid future flare-ups. It’s meant to see if NSAIDs can reduce the chance of symptoms returning and keep disease activity low over time.
Xiamen, FujianAges 18 years+ - NCT05348148Recruiting
Compare treatments for moderate to severe rhinitis symptoms
This trial compares different ways to reduce rhinitis symptoms in people with moderate to severe nasal irritation. It may help find which treatment works best for you, depending on what type of rhinitis you have and your recent health and medication history.
Luodong, YilanAges 6–65 - NCT05362136Recruiting
Sinus lift with different perforations to grow new bone
This trial studies how many small openings (perforations) are made in the sinus floor during a sinus lift procedure, to see which approach helps form more new bone. You might consider it if you need sinus floor elevation on both sides for dental bone support.
ViennaAges 18–120 - NCT04951635RecruitingPhase 3
Almonertinib after chemoradiation for stage III lung cancer
This Phase 3 trial tests whether almonertinib given after standard chemoradiation can help people with stage III, non-surgical lung cancer live longer and/or control the cancer. It is for tumors with specific EGFR mutations linked to sensitivity to EGFR-targeted medicines.
Ji'nan, ShandongAges 18 years+ - NCT05341141Recruiting
