Using advanced genetic testing to diagnose hard-to-find respiratory infections
This study uses a powerful genetic test (next-generation sequencing) to find the cause of respiratory infections when standard tests fail. It may help identify hard-to-detect viruses, bacteria, or fungi in your lung or airway samples.
Nantong, JiangsuAges 18 years+ - NCT06775106Recruiting
Breath test to find lung infections faster
This study tests a new breath analysis method to quickly diagnose respiratory infections in ICU patients on breathing machines. If successful, it could lead to faster treatment for serious lung conditions.
Portland, OregonAges 18–120 - NCT06538480RecruitingPhase 4
Zopa retreatment study for recurrent respiratory papillomatosis
This trial tests if people with recurrent respiratory papillomatosis (growths in the airway caused by HPV) can safely get more doses of the study drug Zopa and checks if the virus spreads after treatment. It may help people who have already tried Zopa or are considering it for the first time.
Atlanta, GeorgiaAges 18 years+ - NCT05655182RecruitingPhase 1/Phase 2
RSV vaccine study for infants and toddlers who may be at risk
This Phase 1/2 study tests an RSV vaccine (BLB-201) in infants and young children. It aims to see how the vaccine works and how safe it is, including in children who already have RSV antibodies or not.
La Mesa, CaliforniaAges 6 months–5 years - NCT07762014RecruitingPhase 2
A new vaccine for respiratory infections in adults 60 and older
This trial tests a new vaccine designed to help protect older adults from infections that can affect breathing. You might be able to join if you're in generally good health and meet the other requirements listed below.
AthensAges 60 years+ - NCT07628049RecruitingPhase 1/Phase 2
RSV and hMPV combination vaccine study for adults
This study tests a new vaccine that may protect against two common viruses that cause breathing problems, RSV and hMPV. It is for healthy younger adults (18-49) and older adults (60-80) to see if the vaccine is safe and works well.
Stockbridge, GeorgiaAges 18–80 - NCT06881953Recruiting
Preventing RSV in infants in France
This trial studies ways to prevent RSV infections in newborns. If you are a parent who gave birth in France between October 2024 and January 2025, you may be able to help researchers learn how to better protect babies from RSV.
ParisAges 18 years+ - NCT06998264Recruiting
Immune response to flu in young children
This study looks at how children's immune systems fight the flu in the nose and throat. It aims to understand why some children get very sick and others don't, which could help create better treatments and vaccines.
GenevaAges 2–5 - NCT06319274RecruitingPhase 2
Prostacyclin for lung infection patients on a ventilator
This study tests a medicine called prostacyclin (given through a vein) to see if it helps people on a breathing machine with a lung infection. The goal is to reduce inflammation and improve recovery.
CopenhagenAges 18 years+ - NCT06401720Enrolling by invitation
Flu immune response study by age
This study looks at how the immune system reacts to the flu in people of different ages. If you have flu symptoms and don't have cancer or take immune-suppressing drugs, you may be able to join.
SödertäljeAges 18 years+ - NCT07358910Recruiting
Tracking infectious diseases in communities
This study looks at how infections spread in villages in Cambodia. If you live in a participating village, you might help us understand and prevent disease outbreaks.
Phnom Penh, Phnom PenhAges 2–75 - NCT05656105RecruitingEarly Phase 1
PET scan study of brain inflammation after COVID
This early-phase study uses a special PET scan to look for signs of brain inflammation in people with ongoing (long-term) nervous system symptoms after COVID-19. It may help researchers understand what is driving symptoms and whether this imaging approach can detect inflammation.
Birmingham, AlabamaAges 18–65 - NCT04256798RecruitingPhase 3
Respiratory care after high-risk abdominal surgery
This trial looks at a breathing-focused care plan given around the time of major abdominal surgery to improve recovery and outcomes. You may be eligible if you’re having a large midline abdominal incision and can be followed after surgery.
Botucatu, São PauloAges 10–100 - NCT04448145Recruiting
Study why COVID lasts after recovery
This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
New York, New YorkAges 7 years+ - NCT03120481Recruiting
Check how respiratory health changes in people without lung problems
This trial enrolls adults who recently had a chest X-ray as part of routine health screening and did not show major abnormal findings, and who do not have significant breathing symptoms. It may help researchers understand changes in respiratory health over time and improve how respiratory disease risk is monitored.
Seoul, SeoulAges 19–90 - NCT06996834Recruiting
Comparing breathing support methods for pneumonia-related breathing failure
This trial tests two noninvasive breathing support methods (NIV and HVNI) for people with pneumonia who are having trouble breathing. The goal is to see which method works better to help you avoid needing a breathing tube.
Asyut, AssuitAges 18 years+ - NCT07356583Recruiting

Common questions
- Are there clinical trials for respiratory infection?
- Yes. Clin2 currently lists 143 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.
