Recruiting studies
- NCT07215871Enrolling by invitationPhase 1
Second H10N7 flu challenge for prior participants
This study tests whether people who have already been exposed to a lab-made H10N7 flu virus can be safely exposed again. It checks how their immune system responds and how long they shed the virus, in a controlled, isolated setting.

Modified measles vaccine schedule to help prevent allergies in babies
This study tests whether changing the measles vaccine timing in 6-month-old children can reduce allergy risk and also help protect against unrelated infections. If your child is already up to date with routine vaccines, they may be eligible for a modified measles (MMR) schedule used in the trial.
GenevaAges 6 months–6 months - NCT07849491Enrolling by invitation
Pharmacist-led antibiotic review for respiratory infections
This study tests whether a pharmacist-led deprescribing strategy—carefully reviewing and possibly reducing or stopping antibiotics that may not be needed—can improve safety and outcomes in patients with respiratory infections taking azithromycin.

Santiago, Santiago MetropolitanAges 60–80 - NCT02979951Recruiting
IV fosfomycin for serious bacterial infections
This trial studies whether IV (through a vein) fosfomycin can treat severe bacterial infections in adults. It may help people whose infection is covered by the standard fosfomycin use and who need hospital-level care.
Hall in TirolAges 18 years+ - NCT07717372Recruiting
CRP test for adults with respiratory infection in primary care
This trial tests whether a simple finger-prick test (C-reactive protein or CRP) can help doctors decide whether antibiotics are needed for adults with a cold or other respiratory infection. If you are an adult with recent symptoms and have not taken antibiotics yet, you may be able to join.
JakartaAges 18 years+ - NCT07694648Recruiting
Watching for germs that cause breathing problems
This study tracks patients with breathing problems to see which germs are making them sick. Doctors will use tests and medical records to watch for different pathogens.
Beijing, Beijing MunicipalityAges Any age - NCT07610967Recruiting
Light therapy for respiratory infection protection
This study tests a mouthpiece that uses light to help the immune system fight respiratory infections. It may reduce the chance of getting sick.
Nellis Air Force Base, NevadaAges 18 years+ - NCT07599449Recruiting
Tracking respiratory infections in French primary care
This study tracks viruses that cause sudden colds and flu-like illnesses during winter months in France. Researchers collect information from patients seen by participating doctors to better understand which respiratory viruses are circulating and help prepare for future outbreaks.
ParisAges Any age - NCT07536035Recruiting
Comparing Hospital Care Pathways for Acute Medical Illness
This study compares two different hospital care pathways for adults admitted with acute medical emergencies like infections, falls, or COPD flare-ups. The goal is to see which pathway provides more appropriate and effective care.
SingaporeAges 21 years+ - NCT07532941RecruitingPhase 4
Stopping antibiotics early versus completing the full course
This study compares two ways of giving antibiotics to children: stopping when symptoms feel better versus finishing all the prescribed doses. Researchers want to see if stopping early is safe and works just as well, which could help reduce unnecessary antibiotic use.
Melbourne, VictoriaAges 1–17 - NCT06472219RecruitingPhase 3
PREDICATE trial for serious lung infections
This trial tests a new approach to treating serious respiratory infections in hospitalized adults. It aims to see if a targeted strategy works better than standard care while avoiding extra risks.
Hong KongAges 18 years+ - NCT07396428Recruiting
Reducing antibiotic use for respiratory infections in Swiss primary care
This study tests whether following a national guideline for treating common respiratory infections (like colds, sore throats, or bronchitis) can help doctors in Switzerland prescribe fewer antibiotics. It focuses on primary care physicians and clinics in certain cantons who are willing to participate in surveys and interviews.
Lausanne, Canton of VaudAges Any age - NCT07381790Recruiting
Modern tools for lung infections in children
This study tests modern technology for diagnosing and treating lower respiratory infections in children. It may help kids with symptoms like fast breathing, wheezing, or chest retractions.
Ålesund, Møre og RomsdalAges birth–2 years - NCT07297966RecruitingPhase 2
Probiotics for recurrent respiratory infections in children
This trial tests if a daily probiotic can help young children who get frequent respiratory infections like colds and coughs. It aims to see if the probiotic reduces how often infections happen.
Xingyi, GuangdongAges 1 day–6 years - NCT07292857Recruiting
Respiratory infection risk in postmenopausal women on HRT or not
This study looks at how the risk of respiratory infections (like colds or flu) may differ in postmenopausal women who use hormone replacement therapy (HRT) and those who do not. You will wear a smartwatch for six months and track your health through a smartphone app.
BernAges 40–60 - NCT06655272RecruitingPhase 4
OM 85 to prevent lung infections in older nursing home residents
This study tests a medication called OM 85 that may help prevent respiratory infections (like pneumonia) in older adults living in nursing homes. If you are 75 or older and have had infections recently, this trial could be a way to stay healthier.
Roma, RMAges 75 years+ - NCT07278700Recruiting
Fever and respiratory infection study
This study looks at adults with a fever caused by a respiratory infection. If you qualify, you will have a blood draw as part of your regular care, and researchers will use it to learn more about your condition.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07261969Recruiting
Blood test and leaflet to guide antibiotic use for respiratory infections
This trial tests if a quick blood test (C-reactive protein, CRP) and a patient leaflet can help doctors prescribe antibiotics only when needed for adults with respiratory tract infections. It aims to reduce unnecessary antibiotic use.
Sokuluk Village, Chui RegionAges 18–70 - NCT07249996Recruiting
Respiratory infections in young babies
This study watches babies under 29 days old to track and understand respiratory infections. It may help doctors learn how to better protect very young infants.

Common questions
- Are there clinical trials for respiratory tract infections?
- Yes. Clin2 currently lists 86 recruiting respiratory tract infections studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a respiratory tract infections trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a respiratory tract infections trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
