Recruiting studies
- NCT05814237Recruiting

This trial tests if remdesivir can safely treat RSV (a respiratory virus) in people with weakened immune systems, such as those who have had a stem cell or bone marrow transplant, CAR T-cell therapy, or are being treated for blood cancer. If you have a confirmed RSV infection in your nose or throat and are at moderate or high risk for complications, you may be able to join.

SingaporeAges 21 years+ - NCT06876766Recruiting
Lung ultrasound to guide antibiotic use in kids with chest infections
This trial tests whether using a lung ultrasound can help doctors decide if antibiotics are needed for children and teens hospitalized with a lower respiratory tract infection. It may reduce unnecessary antibiotic use.
BeirutAges 3 months–18 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 - NCT00900419Recruiting
Check biomarkers during bronchoscopy in breathing and throat pre-cancer
This study looks at “biomarkers” (measurable signals in samples) taken during bronchoscopy or related procedures in people with severe airway pre-cancer or certain lung/throat cancers, and in healthy volunteers. The goal is to better understand what these biomarkers mean and how they might help with diagnosis, staging, or monitoring.
Aurora, ColoradoAges 21–90 - 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 - NCT06917573RecruitingPhase 2
Cemiplimab for advanced lung cancer with high PD-L1
This trial tests a drug called cemiplimab (an immunotherapy) for people with advanced lung cancer that has high PD-L1 levels. It uses a simple blood test to track how well the treatment is working.
Alicante, AlicanteAges 18 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+ - NCT07149428Enrolling by invitation
Deep study of smell loss causes using brain scans
This study uses brain imaging and electrical recordings to understand the brain's role in smell loss from any cause—like COVID, sinus problems, or chemotherapy. You may be eligible if you have any degree of smell loss lasting under a year.
Bethesda, MarylandAges 18–99 - NCT07041671Recruiting
Can a mouth spray reduce virus in breath?
This trial tests whether ColdZyme mouth spray can lower the amount of virus you breathe out when you have a cold or flu-like illness. It may help you recover faster and reduce spreading the virus to others.
LundAges 18 years+ - NCT07498127Enrolling by invitationPhase 2
Probiotics for colds in young children
This trial tests whether taking probiotics can help young children recover faster from common colds. If your child has a mild or moderate cold and is not taking other probiotics, they may be able to join.
Xuhui, Shanghai MunicipalityAges 3 months–6 years - NCT05063149RecruitingPhase 3
Preemie immune treatment to prevent lung infections and wheezing
This study tests whether a bacterial “lysate” medicine, given to preterm babies, can reduce respiratory (lung) infections and wheezing. It may help protect babies’ airways during the vulnerable first months after birth.
Rotterdam, South HollandAges 1 month–2 months - NCT05758532RecruitingPhase 4
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 - NCT06070688Recruiting
A test to tell if your breathing infection is bacterial or viral

Houston, TexasAges 18 years+ - NCT07578012RecruitingPhase 4
Ismigen to prevent respiratory infections in children
This study tests whether a medicine called Ismigen can help children who get frequent respiratory infections (like colds, bronchitis, or throat infections) stay healthier. The medicine is made from bacterial components designed to strengthen the immune system.

Common questions
- Are there clinical trials for respiratory tract diseases?
- Yes. Clin2 currently lists 49 recruiting respiratory tract diseases 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 diseases 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 diseases 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.
