Testing a tool to predict antibiotic-resistant infections in ICU patients
This study validates a prediction tool designed to identify which ICU patients are at risk of developing multidrug-resistant gram-negative bacteria (a serious infection resistant to many antibiotics). The tool may help doctors start appropriate treatment earlier and improve patient outcomes.

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 - 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 - 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+ - 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 - 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 - 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+ - NCT07612644Recruiting
Ultrasound Guidance for Safer Spinal Taps in Babies
This study tests whether using ultrasound to guide lumbar punctures (spinal taps) in babies under 12 months reduces blood contamination in the fluid samples. The goal is to make the procedure safer and more accurate for diagnosing infections or other conditions.
Nashville, TennesseeAges 1 day–1 year - NCT07614490RecruitingPhase 4
Dental plaque and gum health study
This research study examines how dental plaque relates to gum inflammation in people with different levels of gum health. Researchers will collect plaque samples and measure gum health to better understand these patterns, which may help improve oral care products.
Fort Wayne, IndianaAges 18 years+ - NCT07615010RecruitingPhase 2
agenT-797 Plus Standard Care for Severe Pneumonia With Respiratory Failure
This trial tests whether adding an experimental drug called agenT-797 to standard pneumonia treatment helps patients in the ICU who have severe pneumonia and serious difficulty breathing (acute hypoxemic respiratory failure). The drug is designed to help the immune system fight severe infection.
San Francisco, CaliforniaAges 18 years+ - NCT07615517Recruiting
Comparing wound-closure methods for abdominal surgery
This trial compares two ways of closing the layer under your skin after abdominal surgery to see which leads to better healing and fewer complications. You'll be randomly assigned to either have this inner layer stitched or left unstitched.
Augsburg, BavariaAges 18 years+ - NCT07616934RecruitingPhase 1
Safety and immune response study of VAX-A1 vaccine in healthy young adults
This study tests a new vaccine called VAX-A1 in healthy people aged 18–40 to see if it's safe and if it helps the body build protection against Group A Streptococcus (a bacteria that can cause serious infections). You'll receive two vaccine doses and have blood tests and heart monitoring over 6 months.
Adelaide, South AustraliaAges 18–40 - NCT07617376RecruitingPhase 4
Flu shot before leaving hospital after heart problems
This study tests whether giving a flu vaccine to patients before they leave the hospital after a heart condition improves their health. The vaccine may help protect your heart and prevent serious flu complications while you recover.
