Recruiting studies
- NCT07215871Enrolling by invitationPhase 1
Second H10N7 flu challenge for prior participants
This study tests whether people who have already been exposed to a lab-made H10N7 flu virus can be safely exposed again. It checks how their immune system responds and how long they shed the virus, in a controlled, isolated setting.
Bethesda, MarylandAges 18–55 - NCT07633288RecruitingPhase 2
AP1189 Safety and Efficacy for Severe Respiratory Viral Infection
This trial tests whether an experimental drug called AP1189, added to standard hospital care, can help people hospitalized with severe breathing problems from viruses like COVID-19, flu, or RSV. The goal is to see if it reduces the need for mechanical ventilation or other life support.
Mostar, Herzegovina-Neretva CantonAges 18 years+ - NCT07601412Recruiting
Understanding Immune Response to Respiratory Viruses in Older Adults
This study examines how the body's natural defense system (specifically a type of immune protein) responds to common respiratory viruses like flu and cold in older adults. Researchers will analyze nasal samples that are already being collected as part of routine care to better understand why older people sometimes have different immune responses to these infections.
LyonAges 60 years+ - NCT07536035Recruiting
Comparing Hospital Care Pathways for Acute Medical Illness
This study compares two different hospital care pathways for adults admitted with acute medical emergencies like infections, falls, or COPD flare-ups. The goal is to see which pathway provides more appropriate and effective care.
SingaporeAges 21 years+ - NCT07431840Recruiting
Immune protein for respiratory infections in older adults
This trial tests whether an immune defense protein can help reduce upper respiratory infections (like colds) in people aged 60 and older. It may be a good fit if you get colds or flu-like symptoms several times each season.
Los Angeles, CaliforniaAges 60 years+ - NCT07420985RecruitingPhase 2
Ingavirin forte for flu and other viral infections
This trial tests different doses of Ingavirin Forte capsules for treating influenza and other respiratory viruses. It may help people with fever, cough, sore throat, and body aches who have been sick less than 48 hours.
IvanovoAges 18–65 - NCT07388173Recruiting
How respiratory infections affect daily life in older adults
This study looks at how acute respiratory infections (like the flu, COVID-19, or RSV) affect older adults' daily functioning. If you are 60+ and in the hospital with one of these viruses, your participation would help doctors understand the lasting impact on independence and health.
Rochester, New YorkAges 60 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.
CaenAges Any age - NCT07278700Recruiting
Fever and respiratory infection study
This study looks at adults with a fever caused by a respiratory infection. If you qualify, you will have a blood draw as part of your regular care, and researchers will use it to learn more about your condition.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07261969Recruiting
Blood test and leaflet to guide antibiotic use for respiratory infections
This trial tests if a quick blood test (C-reactive protein, CRP) and a patient leaflet can help doctors prescribe antibiotics only when needed for adults with respiratory tract infections. It aims to reduce unnecessary antibiotic use.
Sokuluk Village, Chui RegionAges 18–70 - NCT07249996Recruiting
Respiratory infections in young babies
This study watches babies under 29 days old to track and understand respiratory infections. It may help doctors learn how to better protect very young infants.
Cali, Valle del Cauca DepartmentAges Up to 4 weeks - NCT07222670RecruitingPhase 2
Nasal spray to prevent respiratory infections in healthy adults
This trial tests a nasal spray, INNA-051, that may help your nose and airways fight off viruses that cause respiratory infections like colds and flu. It is for healthy adults aged 18-45 who are around many people and may be exposed to germs.
Baltimore, MarylandAges 18–45 - NCT05536219Recruiting
Study how autoantibodies affect virus levels in severe lung infections
This study measures blood immune “autoantibodies” that may affect how much virus is in the body during severe respiratory infections. It may help doctors understand which patients are more likely to have higher virus levels and could guide future treatment choices.
Bron, RhoneAges Any age - NCT05550298Recruiting
Study of virus infections after pediatric transplants
This study looks at how respiratory viruses behave and how the body responds in children who are about to receive, or have recently received, a transplant. It may help doctors better diagnose and treat viral infections in transplant patients by studying blood samples and test results.
Birmingham, AlabamaAges Up to 18 years - NCT06178822Recruiting
New blood tests to diagnose sepsis in the ER
This study aims to find new ways to quickly diagnose sepsis (a severe response to infection) in patients arriving at the emergency room. If successful, these new tests could help doctors start treatment faster.
Almere Stad, FlevolandAges 18 years+ - 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 - NCT05624450RecruitingPhase 3
Test drug tozorakimab for hospitalized viral lung infection needing oxygen
This Phase 3 study tests tozorakimab to see if it helps people hospitalized with a viral lung infection that is causing low oxygen levels. You might qualify if you still need supplemental oxygen when the study starts.
Birmingham, AlabamaAges 18 years+ - NCT05336851Recruiting
Emergency breathing test study for sudden lung infections
This trial tests an emergency breathing-related approach for adults with a sudden, community-acquired respiratory infection. It may help doctors quickly sort out what’s going on and guide early care.
Hong KongAges 18–100 - NCT06286657Recruiting
Xanthohumol and viral infections study
This study tests whether a natural compound called xanthohumol (found in hops) can help your body fight off common viruses. Healthy adults with a normal BMI are invited to participate.
ViennaAges 18–70 - 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+ - NCT07239583Recruiting
RSV infection and health impact in older adults in Vietnam
This study looks at how common RSV (a virus that can cause serious breathing problems) is in older adults who are hospitalized with respiratory symptoms or worsening heart/lung conditions. By joining, you help researchers understand the virus and improve care for people your age.

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+ - NCT07030673Recruiting
Stopping antibiotics early in older adults with viral infections
This trial tests whether elderly patients hospitalized with a viral lower respiratory infection can safely stop antibiotics early. It aims to reduce unnecessary antibiotic use and side effects.

Common questions
- Are there clinical trials for respiratory viral infection?
- Yes. Clin2 currently lists 53 recruiting respiratory viral 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 viral 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 viral 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.
