Testing HRS-5635 to improve hepatitis B treatment
This study tests whether adding a new drug called HRS-5635 to your current hepatitis B medicine works better than your current treatment alone. You may qualify if your hepatitis B is already controlled with antiviral pills and your viral levels are very low.
Guangzhou, GuangzhouAges 18 years+ - NCT07607470Recruiting
Vaginal Health Symptom Study with New Testing Method
This study tests a new way to diagnose vaginal infections by collecting samples from the vagina. If you have symptoms like unusual discharge, itching, burning, or odor, this research may help improve how doctors identify what's causing your discomfort.
North Miami, FloridaAges 18 years+ - NCT05502380RecruitingPhase 3
Antibiotic prevention study for high-risk bone and spine surgeries
This Phase 3 study tests whether giving a broad set of preventive antibiotics before certain high-risk orthopedic surgeries lowers the chance of serious wound or bone infection. It mainly targets people who have contaminated wounds, tumor-related surgery, or known high-risk germs on the skin.
ZurichAges 18 years+ - NCT06253325Recruiting
Early detection of patients at risk for sepsis
This trial is looking for patients who have an infection and are showing early signs of getting sicker, like a high warning score. It aims to find out if doctors can identify those at risk of sepsis sooner so they can start treatment earlier.
Southampton, HampshireAges 18 years+ - NCT07612163Recruiting
Antibiotic levels and effectiveness in patients with liver cirrhosis
This study measures how antibiotic drugs called beta-lactams work in people with cirrhosis (liver damage). Researchers will check antibiotic blood levels to see if standard doses are right for cirrhotic patients or need adjustment.
Nanjing, JiangsuAges 18 years+ - NCT07607639Recruiting
Gum Health Markers in Children and Young Adults
This study looks at special proteins in the fluid around your gums to understand how gum disease develops in young people. By studying these markers, researchers hope to better understand and treat gum inflammation.
NiğdeAges 8–24 - NCT07611838Recruiting
Predicting ABPA Recurrence Using Blood and Immune Markers
This study helps doctors predict whether allergic bronchopulmonary aspergillosis (ABPA)—a serious lung condition caused by fungal allergy—will come back after treatment. Researchers will analyze blood samples and immune system markers to identify patients at higher risk of relapse, which could improve how doctors monitor and treat you.
Jinan, ShandongAges 18–80 - NCT07609576Recruiting
Tracking Infections in Blood Cancer Patients on Bispecific Antibody Treatment
This study follows adults with blood cancers (like multiple myeloma or lymphoma) who are starting a newer type of immunotherapy called bispecific antibodies. Researchers want to understand what infections might develop during this treatment and how often they occur, which could help doctors better protect patients.
Madrid, MadridAges 18 years+ - NCT07607288Enrolling by invitation
Tracking TB Treatment Results and Side Effects
This study follows patients being treated for tuberculosis with standard medications to see how well the treatment works and what side effects occur. Your medical records and check-ups help doctors understand which treatments are most effective.
Beijing, Beijing MunicipalityAges 5 years+ - NCT07610486RecruitingPhase 1/Phase 2
Better ampicillin dosing for preterm infants
This study gives preterm babies the standard antibiotic ampicillin and checks the amount in their blood to find the best dose. It may help make sure the medicine works well and is safe for babies born early.
Durham, North CarolinaAges birth–1 week - NCT07610772RecruitingPhase 1
Safety study of a new hepatitis B antibody for hepatitis D
This early-stage trial tests whether a new monoclonal antibody (a lab-made protein that fights viruses) is safe and effective in people with chronic hepatitis D infection. Hepatitis D only occurs in people who also have hepatitis B, and this new treatment may help control the virus.
AarhusAges 18–70 - NCT07604103RecruitingPhase 3
Heart Attack and Pneumonia Recovery Study With Vaccination
This study looks at blood markers (special proteins) in patients who have had both a heart attack and pneumonia, to see how vaccination affects recovery. The goal is to understand whether flu and pneumonia vaccines are safe and helpful for people recovering from these two serious conditions together.
Malang, East JavaAges 18–65 - NCT06711575Recruiting
