Recruiting studies
- NCT06490744Recruiting
Lung function after COVID-19 in lung transplant patients
This study looks at how lung function changed over time in lung transplant patients who had a moderate to severe COVID-19 infection. It may help doctors understand how to better care for transplant patients after a serious COVID-19 illness.
StrasbourgAges 18 years+ - NCT06467864Recruiting
Predicting lung infection outcomes using early bacteria tests
This trial tests a new way to predict how well patients with a ventilator-associated lung infection will respond to treatment. It uses two bronchoscopy samples to track bacteria levels and guide better care.
Nanjing, JiangsuAges 18 years+ - NCT05762302Recruiting
Testing a blood test to guide antibiotics for lung infections
This trial studies whether using the MeMed BV® blood test in the emergency room or urgent care can help doctors decide when antibiotics are (or are not) needed for suspected lung infections. It may help reduce unnecessary antibiotics while still treating infections when needed.
Jacksonville, FloridaAges 18–99 - NCT07292857Recruiting
Respiratory infection risk in postmenopausal women on HRT or not
This study looks at how the risk of respiratory infections (like colds or flu) may differ in postmenopausal women who use hormone replacement therapy (HRT) and those who do not. You will wear a smartwatch for six months and track your health through a smartphone app.
BernAges 40–60 - NCT07532941RecruitingPhase 4
Stopping antibiotics early versus completing the full course
This study compares two ways of giving antibiotics to children: stopping when symptoms feel better versus finishing all the prescribed doses. Researchers want to see if stopping early is safe and works just as well, which could help reduce unnecessary antibiotic use.
Melbourne, VictoriaAges 1–17 - NCT07582796RecruitingPhase 1/Phase 2
RSV Vaccine Study for Adults in China
This study tests a new vaccine to protect against RSV (a common respiratory virus that causes cold-like illness, especially serious in older adults). The vaccine is made in laboratory cell cultures and includes an immune-boosting ingredient. Researchers want to see if it's safe and if it helps your body fight RSV infection.
Zigong, SichuanAges 18 years+ - NCT06817889RecruitingPhase 2
Remdesivir for RSV in people with weak immune systems
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.
Duarte, CaliforniaAges 18 years+ - NCT06402318Recruiting
Quick breath test for COVID, flu, and RSV
This study tests a breathalyzer device that quickly detects COVID-19, flu, and RSV from your breath. If you are already being tested for these viruses, you may join to see if this new method works as well as the usual swab test.
Fort Sam Houston, TexasAges 18–89 - 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+ - NCT06495021Recruiting
Osteopathic manipulation for newly diagnosed respiratory illness in older adults
This study tests whether osteopathic manipulation (a gentle hands-on treatment) helps older adults recover from common respiratory illnesses like bronchitis or pneumonia when added to regular care. It may be a good option for you if you're 65 or older and have just been diagnosed with a respiratory infection.
Bloomsburg, PennsylvaniaAges 65–100 - NCT06197152Recruiting
RSV severity markers in hospitalized adults
This study looks for markers in the blood that can tell how serious an RSV infection might become. If you are hospitalized with RSV and have breathing symptoms, this trial will follow your recovery and test for clues about your illness.
CréteilAges 18 years+ - NCT06560255RecruitingPhase 3
Fish oil in pregnancy to prevent childhood asthma
This study tests if taking fish oil during pregnancy can help lower the risk of childhood asthma. If you have low omega-3 levels, you may be randomly assigned to receive fish oil or a placebo.
Gentofte MunicipalityAges 18–45 - NCT06570889RecruitingPhase 3
Vitamin D in pregnancy to prevent early childhood asthma
This trial tests if taking extra vitamin D during pregnancy can prevent asthma in young children. It is for pregnant women in Denmark who already have certain healthy fat levels in their blood.
Gentofte MunicipalityAges 18–45 - NCT06643039Recruiting
Study on hospital-acquired respiratory virus infections
This trial looks at respiratory viruses caught in the hospital. If you are an adult patient or healthcare worker with flu-like symptoms that started while in the hospital, you may help researchers learn more about these infections.
BordeauxAges 18 years+ - NCT07000877RecruitingPhase 4
Nasal spray to help kids with colds during anesthesia
This study tests whether a nasal decongestant spray can help prevent breathing problems during anesthesia for children with a cold. If your child has a recent cold and is having surgery, this could help make the anesthesia safer.
Perth, WeAges 1–8 - NCT02498587Recruiting
Study of severe breathing illness over a short period
This study looks at people who recently had fever and cough along with trouble breathing, to better understand severe acute respiratory illness. By joining, you may help researchers identify patterns that could improve recognition and care.
Melbourne, VictoriaAges Any age - 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+ - 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 - NCT06775405RecruitingPhase 3
Testing a new RSV treatment for hospitalized babies
This study tests a medicine called AK0529 for babies and toddlers hospitalized with RSV. It aims to see if the drug helps them recover faster and is safe for this age group.
BeijingAges 1 month–2 years - NCT04545242RecruitingPhase 4
Dexamethasone for severe lung failure from infections on ventilators
This trial studies whether dexamethasone (a steroid medicine) improves outcomes in adults who have sudden, severe breathing failure caused by an infection while they are on a breathing machine. It may help reduce inflammation in the lungs during critical illness.
Terrassa, BarcelonaAges 18 years+ - NCT07093749Recruiting

This study looks at how children with common infections feel while taking antibiotics. The goal is to better understand symptom patterns during treatment.
Melbourne, VictoriaAges 4–17 - NCT06765135Enrolling by invitation
Respiratory test for smarter antibiotic use
This trial tests a quick, point-of-care test for respiratory infections in primary care. The goal is to help doctors decide when antibiotics are needed, reducing unnecessary use.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07147517Recruiting
Tracking respiratory viruses in your community and home
This study tracks how respiratory viruses spread in the community and within households. It involves testing and collecting samples from people who are sick or healthy, to help better understand and prevent 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.
