Recruiting studies
- 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.

Zelicapavir for RSV in infants and toddlers
This trial tests a new medicine called Zelicapavir for babies and young children (28 days to 3 years old) who have respiratory syncytial virus (RSV) infection. The medicine aims to help them recover faster and with fewer complications.
BangkokAges 4 weeks–3 years - 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 - 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.
MurciaAges 3–12 - NCT07658534RecruitingPhase 2/Phase 3
Ziresovir for high-risk adults with RSV
This trial tests an antiviral drug called Ziresovir in adults with RSV who have health conditions that make them high-risk, such as lung disease, heart disease, or a weakened immune system. It aims to see if the drug can reduce symptoms like coughing and shortness of breath.
Beijing, Beijing MunicipalityAges 18–85 - NCT07207291RecruitingPhase 1
Study of JKN2501 in healthy volunteers
This trial tests a new drug called JKN2501 in healthy people to find the best and safest dose. It is the first time this drug is being given to humans.
Changsha, HunanAges 18–45 - 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+ - NCT05474430Recruiting
Study testing how common lung infections relate to CF gene status
This study looks at whether carrying one CF gene (being a “CF carrier”) changes the risk of getting respiratory infections. It may help researchers understand how genetics can affect lung health, even for people who do not have cystic fibrosis.
Iowa City, IowaAges 18–100 - NCT06902194Recruiting
Kids' immune response to respiratory infections study
This study looks at how South African children's immune systems respond to acute respiratory infections. It may help find better ways to treat or prevent these infections.
Cape Town, Western CapeAges Up to 13 years - 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+ - 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 - NCT06715306Recruiting
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+ - 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 - 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 - 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+ - 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+ - 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 - NCT07229677Recruiting
Arbovirus and emerging virus infections study in Fiji
This study is looking at how viruses like those spread by mosquitoes (arboviruses) affect people in Fiji. If you join, researchers will track your health over time to find better ways to prevent and treat these infections.
Suva, CentralAges 6 years+ - NCT07314905RecruitingPhase 3
Treatments for respiratory infections in community settings
This study is testing different treatments for people with respiratory infections like the flu who are not in the hospital. You may be able to join if you have a positive test, have symptoms like cough or fever, and start within a few days of feeling sick.
Toronto, OntarioAges 18 years+ - NCT07359287Recruiting
Study on antibiotic use for respiratory infections
This study tests a program to help doctors prescribe antibiotics more carefully for common respiratory infections like colds, flu, bronchitis, and sinusitis. It may lead to better treatment for you.

Common questions
- Are there clinical trials for respiratory infection?
- Yes. Clin2 currently lists 150 recruiting respiratory infection 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 infection 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 infection 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.
