IV vs. Oral Antibiotics for Common Infections
This trial compares starting antibiotics through a vein (IV) to taking them by mouth for common infections like pneumonia, urinary tract infections, or skin infections (cellulitis). The goal is to see if oral antibiotics work just as well without the need for an IV line.

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+ - NCT06902194Recruiting

Preventing colds in kids with a probiotic
This trial tests if a daily probiotic (Lacticaseibacillus rhamnosus CRL1505) can help prevent upper respiratory infections (like colds and sore throats) in healthy children ages 3 to 12. If your child often gets sick, this supplement might reduce how often they catch a cold.
MurciaAges 3–12 - NCT07207291RecruitingPhase 1
Study of JKN2501 in healthy volunteers
This trial tests a new drug called JKN2501 in healthy people to find the best and safest dose. It is the first time this drug is being given to humans.
Changsha, HunanAges 18–45 - NCT07249996Recruiting

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 - 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+ - 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 - NCT07297966RecruitingPhase 2
Probiotics for recurrent respiratory infections in children
This trial tests if a daily probiotic can help young children who get frequent respiratory infections like colds and coughs. It aims to see if the probiotic reduces how often infections happen.
Xingyi, GuangdongAges 1 day–6 years - NCT06363370RecruitingPhase 3

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 - 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 - 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+ - NCT07651865Recruiting

Bethesda, MarylandAges 18–55 - NCT03299608Recruiting
Breath test to quickly detect infections in blood cancer patients
This study tests whether a quick breath test can detect infections early in people receiving intensive treatment for certain blood cancers or bone marrow transplant patients. If it works, it could help doctors find infections faster and adjust treatment sooner.
LeuvenAges 18 years+ - NCT05819229Recruiting
Antibiotics by mouth only for young babies with urine infection

- Yes. Clin2 currently lists 86 recruiting respiratory tract infections 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 tract infections 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 tract infections 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.
