Recruiting studies
- NCT07154992Recruiting
Preventing colds in kids with a probiotic
This trial tests if a daily probiotic (Lacticaseibacillus rhamnosus CRL1505) can help prevent upper respiratory infections (like colds and sore throats) in healthy children ages 3 to 12. If your child often gets sick, this supplement might reduce how often they catch a cold.

Can a breast-milk sugar supplement prevent colds and stomach bugs?
This study tests a chewable supplement made from a natural sugar found in breast milk (2'-fucosyllactose) to see if it helps prevent colds and stomach bugs in young children who attend daycare or school. It is for healthy children between 1 and 4 years old.
Bari, BariAges 1–4 - NCT06998251Recruiting
Immune response to strep pneumonia in older adults
This study looks at how the immune system in the nose and throat reacts to Streptococcus pneumoniae bacteria and viruses in adults aged 60-85. It may help researchers find better ways to prevent or treat pneumonia.
GenevaAges 60–85 - NCT06876766Recruiting
Lung ultrasound to guide antibiotic use in kids with chest infections

IV vs. Oral Antibiotics for Common Infections
This trial compares starting antibiotics through a vein (IV) to taking them by mouth for common infections like pneumonia, urinary tract infections, or skin infections (cellulitis). The goal is to see if oral antibiotics work just as well without the need for an IV line.
Aabenraa, Southern DenmarkAges 18 years+ - NCT05045612RecruitingPhase 4
Antibiotics for certain viral lung infections in hospitalized adults
This trial studies whether giving antibiotics affects recovery in adults hospitalized with moderately severe infections caused by specific viruses (influenza, parainfluenza, RSV, or hMPV). It may help show when antibiotics are helpful or unnecessary for viral airway illness.
BergenAges 18 years+ - NCT06570889RecruitingPhase 3
Vitamin D in pregnancy to prevent early childhood asthma
This trial tests if taking extra vitamin D during pregnancy can prevent asthma in young children. It is for pregnant women in Denmark who already have certain healthy fat levels in their blood.
Gentofte MunicipalityAges 18–45 - NCT06560255RecruitingPhase 3
Fish oil in pregnancy to prevent childhood asthma
This study tests if taking fish oil during pregnancy can help lower the risk of childhood asthma. If you have low omega-3 levels, you may be randomly assigned to receive fish oil or a placebo.
Gentofte MunicipalityAges 18–45 - NCT06495021Recruiting
Osteopathic manipulation for newly diagnosed respiratory illness in older adults
This study tests whether osteopathic manipulation (a gentle hands-on treatment) helps older adults recover from common respiratory illnesses like bronchitis or pneumonia when added to regular care. It may be a good option for you if you're 65 or older and have just been diagnosed with a respiratory infection.
Bloomsburg, PennsylvaniaAges 65–100 - NCT06387667Recruiting
Fungal lung infections in ICU patients with weak immune systems
This study looks at different types of fungi that may cause serious lung infections in patients with weakened immune systems in the ICU. It aims to find out which fungi are present and which antifungal drugs can kill them.
AsyutAges 18 years+ - NCT06363370RecruitingPhase 3
Interferon inhalation for RSV in children under 2
This trial tests if an inhaled interferon solution can help children under 2 years old with a moderate to severe RSV lung infection. It aims to reduce symptoms like cough and trouble breathing.
Beijing, Beijing MunicipalityAges 2 months–2 years - NCT06331364Recruiting
Treating lung infections with better antibiotic decisions in Sri Lanka
This study tests whether a new way of deciding when to use antibiotics helps patients with lower respiratory infections (like pneumonia or bronchitis) in Sri Lankan hospitals. If you were recently admitted with a new lung infection, you may be able to join.
BalapitiyaAges 14 years+ - NCT06282718Recruiting
Observational study of respiratory infections in primary care
This study tracks how patients with respiratory infections (like bronchitis, sore throats, or COVID-19) are treated in family doctor offices across Europe. The goal is to learn more about these infections and improve care. You may be able to join if you have a cough, sore throat, or other symptoms that suggest a respiratory infection, and you go to a participating clinic.
AntwerpAges Any age - NCT06201494Recruiting
Studying early symptoms of asthma in children
This study follows children and teens who are being checked for asthma for the first time. It aims to learn more about the early symptoms of asthma to improve diagnosis and treatment.
PragueAges 3–18 - NCT05762302Recruiting
Testing a blood test to guide antibiotics for lung infections
This trial studies whether using the MeMed BV® blood test in the emergency room or urgent care can help doctors decide when antibiotics are (or are not) needed for suspected lung infections. It may help reduce unnecessary antibiotics while still treating infections when needed.
Jacksonville, FloridaAges 18–99 - NCT05661032Recruiting
Testing new ways to identify respiratory viruses
This study tests “new technologies” to identify what virus is causing a respiratory illness, using samples taken from inside your nose. It may help doctors get faster, more accurate answers about the cause of your symptoms.
Portsmouth, HampshireAges Any age - NCT03808922RecruitingPhase 3
DAS181 treatment for COVID-19 lung infection in immune-compromised adults
This Phase 3 trial tests DAS181 to treat lower lung (chest) viral infections in people with weakened immune systems, including a COVID-19 subgroup. It may help by targeting certain viruses in the lungs, but joining depends on your oxygen needs, recent diagnosis, and other safety factors.
Duarte, CaliforniaAges Any age - NCT06896643Recruiting
Urine infections and bone surgery in older adults

Common questions
- Are there clinical trials for respiratory tract infections?
- Yes. Clin2 currently lists 87 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.
