Alcohol and drug effects on immunity in ICU breathing patients
This study looks at how alcohol and other drugs can affect the body’s immune system in people who are very sick in the ICU due to breathing problems. It may help doctors better understand immune changes during critical illness and respiratory failure.

Testing a New Antiviral Medicine Formulation in Healthy Adults
This study compares two versions of an antiviral medicine called Ingavirin to see how your body processes them and whether they are safe. Researchers will give you the medicine on an empty stomach and after eating to understand how food affects how your body absorbs it.
Saint PetersburgAges 18–45 - NCT07383350Enrolling by invitation
Information sheets for better communication on antibiotics
This study tests if using simple information sheets helps you and your doctor talk better about infections like sore throat, sinusitis, or bronchitis, and make wise decisions about antibiotics — so you only get them when truly needed.
AalborgAges 18 years+ - NCT06521892Enrolling by invitation

RSV and hMPV vaccine study in younger and older adults
This study tests two investigational vaccines designed to protect against RSV (respiratory syncytial virus) and hMPV (human metapneumovirus), which are common respiratory viruses. Researchers want to see if these vaccines are safe and help the body fight these infections in adults aged 18–80.
Lenexa, KansasAges 18–80 - 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 - NCT05973201Recruiting
Virtual reality to ease anxiety and pain during lung scope
This study tests whether virtual reality (VR) can reduce anxiety and pain and shorten the time during a non-emergency breathing tube/airway procedure in the ICU. If you’re eligible, you may use VR during your first bronchoscopy during this hospital stay.
Aix-en-ProvenceAges 18 years+ - 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+ - 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 - NCT07283497RecruitingPhase 4
Itraconazole for bronchiectasis with airway mold growth
This Mayo Clinic study tests whether the oral antifungal drug itraconazole can help people with bronchiectasis who have mold growing in their airways. The goal is to see if it improves symptoms and reduces mold in the lungs.
Rochester, MinnesotaAges 18 years+ - 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+ - NCT06266442Recruiting
DNA study of M. avium in lung infection
This study looks at the DNA of the bacteria causing your lung infection (Mycobacterium avium) to understand treatment better. It involves analyzing stored samples and may include patients who have been treated before.
Toronto, OntarioAges 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.

Common questions
- Are there clinical trials for respiratory infection?
- Yes. Clin2 currently lists 149 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.
