Recruiting studies
- 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.

Study of new respiratory infections starting within 10 days
This is an observational study that follows adults who are newly sick with a respiratory infection that started within the past 10 days. It may help researchers understand what causes these infections and how patients do in emergency or hospital-care settings.
BrusselsAges 18 years+ - NCT07694648Recruiting
Watching for germs that cause breathing problems
This study tracks patients with breathing problems to see which germs are making them sick. Doctors will use tests and medical records to watch for different pathogens.
Beijing, Beijing MunicipalityAges Any age - NCT06736288RecruitingPhase 4
Buccalin® tablets to prevent repeat lung infections
This trial tests whether Buccalin® tablets can help adults who get frequent lower respiratory infections (like bronchitis or COPD flare-ups). It's a phase 4 study collecting more data on safety and how well the medicine works to prevent these infections from coming back.
AlessandriaAges 18–99 - 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 - 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 - NCT07651865Recruiting
Testing New Ways to Diagnose Respiratory Infections
This study tests new diagnostic tools to help quickly identify what's causing your respiratory infection. You'll provide samples (like nasal swabs) to help researchers understand how these new tests work in real patients.
Addis AbabaAges 6 months+ - 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 - 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+ - NCT07739446Enrolling by invitation
Do face masks help prevent catching the flu or COVID-19?
This trial looks at whether wearing surgical masks when out in public can reduce your chances of getting the flu or COVID-19. If you join, you'll be assigned by chance to either wear a mask outside for 3-4 months or not wear one, and you'll be tested if you get sick.
ChibaAges 20–49 - 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 - NCT07050693Recruiting
Can a breast-milk sugar supplement prevent colds and stomach bugs?
This study tests a chewable supplement made from a natural sugar found in breast milk (2'-fucosyllactose) to see if it helps prevent colds and stomach bugs in young children who attend daycare or school. It is for healthy children between 1 and 4 years old.
Bari, BariAges 1–4 - 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.
Ho Chi Minh City, Southern VietnamAges 60 years+ - 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+ - NCT07314593Recruiting
Fish oil for preventing colds and respiratory infections
This trial tests whether taking fish oil with free fatty acids can help healthy adults avoid colds and other respiratory infections. If you are generally healthy and willing to take fish oil capsules daily, you may be able to join.
ReykjavikAges 18–80 - NCT07396428Recruiting
Reducing antibiotic use for respiratory infections in Swiss primary care
This study tests whether following a national guideline for treating common respiratory infections (like colds, sore throats, or bronchitis) can help doctors in Switzerland prescribe fewer antibiotics. It focuses on primary care physicians and clinics in certain cantons who are willing to participate in surveys and interviews.
Lausanne, Canton of VaudAges Any age - NCT06472219RecruitingPhase 3
PREDICATE trial for serious lung infections
This trial tests a new approach to treating serious respiratory infections in hospitalized adults. It aims to see if a targeted strategy works better than standard care while avoiding extra risks.
Hong KongAges 18 years+ - NCT06363370RecruitingPhase 3
Interferon inhalation for RSV in children under 2
This trial tests if an inhaled interferon solution can help children under 2 years old with a moderate to severe RSV lung infection. It aims to reduce symptoms like cough and trouble breathing.
Beijing, Beijing MunicipalityAges 2 months–2 years - NCT05164744Recruiting
MRI study of heart tissue changes after COVID-19
This study uses a heart MRI to look for leftover (healing) changes in heart tissue after COVID-19. It may help researchers better understand what ongoing heart effects can happen after infection.
Brooklyn, New YorkAges 18 years+ - NCT05123755RecruitingPhase 2
Testing a new medicine in hospitalized pneumonia patients needing oxygen
This Phase 2 trial tests an investigational medicine (given in increasing doses) for hospitalized people with pneumonia who need supplemental oxygen. It aims to see if the medicine is safe and potentially helps the pneumonia process in the early hospital period.

Two Doses of PRS CK STORM for Severe Viral Pneumonia
This study tests a new drug called PRS CK STORM to see if it can safely calm the body's overactive immune response (cytokine storm) in people with severe pneumonia from COVID-19, flu, or RSV who need oxygen. It aims to reduce inflammation and improve recovery.

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.
