Lung response to inhaled immune stimulant in healthy and asthma
This study tests how the lungs react to breathing in a weak immune-stimulating drug (R848). It includes healthy volunteers and people with mild to moderate asthma to see differences in airway responses.
Cambridge, CambridgeshireAges 18–60 - NCT06489964Recruiting
Paying for unfunded vaccines at your pharmacy
This trial tests a way for you to get vaccines that are recommended but not free, like FluMist for kids, Shingrix for shingles, or RSV vaccines. You pay a copayment at a participating pharmacy instead of the full price.

Rigid corset for spine infection: a care practice study
This study looks at how rigid corsets are used to immobilize the spine in patients with a spinal infection called spondylodiscitis. It aims to understand current practices and may help improve care.
Clermont-FerrandAges 18 years+ - NCT06490744Recruiting
Lung function after COVID-19 in lung transplant patients
This study looks at how lung function changed over time in lung transplant patients who had a moderate to severe COVID-19 infection. It may help doctors understand how to better care for transplant patients after a serious COVID-19 illness.

Comparing immune responses in bacterial vs. COVID-19 sepsis
This study compares how the body's immune system responds to bacterial sepsis vs. viral sepsis (COVID-19) in intensive care unit patients. The goal is to find better ways to treat each type of life-threatening infection.
Chengdu, SichuanAges 18–90 - NCT06492187Recruiting
Survey to see if you qualify for infectious disease studies
This trial is a quick survey to see if you might be eligible for future infectious disease studies. It helps researchers understand your health background and find the right study for you.
Brooklyn, New YorkAges 18 years+ - NCT06492798RecruitingPhase 1/Phase 2
Stem cells for Long COVID: a safety and effectiveness study
This study tests whether a single infusion of mesenchymal stem cells can help with Long COVID symptoms—without causing serious side effects. It’s for people who are still struggling with COVID-related health problems months after their initial infection.
ShanghaiAges 18–70 - NCT06492668Recruiting
Tick exposure and prevention study for Alsace foresters
This study looks at how foresters in Alsace are exposed to ticks and tick-borne diseases, and how to prevent them. The goal is to better protect forestry workers from these risks.
Strasbourg, Les Hôpitaux Universitaires de StrasbourgAges 18 years+ - NCT06494072RecruitingPhase 4
Short vs standard antibiotics for kids hospitalized with pneumonia
This trial compares a shorter course of antibiotics to the usual longer course for children hospitalized with uncomplicated bacterial pneumonia. The goal is to see if fewer days of antibiotics work just as well, which could reduce side effects and make treatment easier.
Milwaukee, WisconsinAges 3 months–18 years - NCT06497465RecruitingPhase 3
HIV study for people starting TB treatment
This trial tests a two-drug HIV treatment (dolutegravir and lamivudine) for people who also have active TB and are taking a standard TB medicine called rifampin. It is designed for those who have not yet started HIV treatment.
Manaus, AmazonasAges 15–99 - NCT06498310Recruiting
Fungal infections in heart transplant patients (2008–2022)
This study looks back at heart transplant patients who had a serious fungal infection from thread-like fungi (like mold) between 2008 and 2022. It aims to learn more about these infections to improve care for future patients.
StrasbourgAges 18 years+ - NCT06498414RecruitingPhase 2/Phase 3
Shorter and safer treatment for latent TB
This trial tests a shorter, safer treatment for people with latent TB infection (TB germs in your body but not making you sick). The goal is to prevent you from getting sick with active TB later.
CotonouAges 5 years+ - NCT06498817Recruiting
Cholera home care for diarrhea patients without running water
This trial tests a 7-day hospital-based program to help patients with diarrhea who lack running water at home. It aims to prevent the spread of cholera and improve recovery.

Study on preventing pneumocystis pneumonia in autoimmune disease
This trial tests whether a preventive treatment can stop pneumocystis pneumonia (a lung infection) in people with autoimmune inflammatory rheumatic diseases who are taking steroids or other immune-suppressing medicines. It aims to find the safest and most effective way to protect you from this serious infection.
Wuhan, HubeiAges 18 years+ - NCT06499467Recruiting
Comparing second blood pressure medicines for septic shock
This trial tests different combinations of blood pressure medicines given to patients on a breathing machine who have septic shock. The goal is to find the best dose of a second medicine when norepinephrine alone isn't enough.
Lucknow, Uttar PradeshAges 18–80 - NCT06499701Recruiting
Study of Fluid Resuscitation in Early Sepsis
This trial studies how different fluids given to treat early sepsis affect the body's fluid balance. Participating may help researchers find better ways to treat sepsis-related low blood pressure and organ failure.
Bucharest, BucharestAges 18 years+ - NCT06500156Recruiting
Metabolic patterns in septic shock patients
This study looks at how the body uses energy (metabolism) in people with septic shock. It collects information from standard monitoring during a fluid challenge (a small IV fluid test) to find patterns that might help doctors better understand and treat septic shock.
Sabadell, BarcelonaAges 18 years+ - NCT06500767Recruiting
Emotional impact of counseling before colposcopy
This study looks at how counseling before a colposcopy affects your emotions and mental well-being. You may take part if you have abnormal cervical screening results and need a closer exam.
