Wuhan, HubeiAges Any age - NCT07334379RecruitingPhase 2
Tailored treatment for acute breathing problems
This trial tests whether using a blood test to measure inflammation (IL-6) can help doctors decide if you should get either dexamethasone or tocilizumab for COVID-19 or other acute breathing problems. The goal is to find the best treatment faster and reduce side effects.
Toronto, OntarioAges 18 years+ - NCT05795465RecruitingPhase 2
Study drug for people with acute respiratory distress syndrome
This Phase 2 trial tests GEn-1124 to see if it can improve outcomes in people with acute respiratory distress syndrome (ARDS). You may be eligible if the study drug can be started very soon after ARDS is diagnosed and if you meet the safety and health requirements.

Vadadustat treatment for lung injury from infection
This trial tests a pill called vadadustat for people with a serious lung condition called ARDS, which makes it hard to breathe. The drug may reduce inflammation and improve oxygen levels, helping patients recover without needing a breathing tube.
Houston, TexasAges 18 years+ - NCT07211529Recruiting
Nerve block during chest surgery to reduce complications
This trial tests whether a numbing injection near the spine (paravertebral block) given during keyhole chest surgery can lower the risk of problems after surgery. It might help patients recover more comfortably.

PET scan study of brain inflammation after COVID
This early-phase study uses a special PET scan to look for signs of brain inflammation in people with ongoing (long-term) nervous system symptoms after COVID-19. It may help researchers understand what is driving symptoms and whether this imaging approach can detect inflammation.
Birmingham, AlabamaAges 18–65 - NCT06876259Recruiting
AI tool to reduce antibiotics for young children with colds
This trial tests whether an artificial intelligence (AI) tool can help doctors decide when antibiotics are not needed for young children with colds. It aims to reduce unnecessary antibiotic use.
Pittsburgh, PennsylvaniaAges 6 months–2 years - 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+ - NCT06076304RecruitingPhase 4
Comparing treatments for acute sinusitis
This trial tests whether nasal steroids, nasal irrigation, or oral antibiotics work best for acute sinusitis. It may help if you have ongoing sinus symptoms or a 'double-sickening' pattern after a cold.
Los Angeles, CaliforniaAges 18–75 - NCT06510972Recruiting
Eating versus fasting for ICU patients with breathing failure
This study looks at whether it's safe and helpful to let people with severe breathing problems in the ICU eat and drink normally instead of fasting. If you qualify, you may be assigned to either continue eating or to fast while doctors monitor your recovery.
BloisAges 18 years+ - NCT07165717Recruiting
Real-world study of breathing emergencies in ICU patients
This study looks at why some patients develop severe breathing problems in the ICU. It focuses on people who already have conditions like severe infections, injuries, or heavy bleeding that can stress the lungs.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07248995Recruiting
Ultrasound to set breathing support in brain injury patients with lung issues
This trial tests if chest and head ultrasound can help doctors adjust the breathing machine (PEEP) for patients with both a severe brain injury and a serious lung condition called ARDS. The goal is to improve care without harming the brain.
ThessalonikiAges 18 years+ - NCT06625944Recruiting
How viral infections affect lung disease
This study looks at how viral infections impact people with chronic lung conditions like COPD or bronchiectasis. It aims to understand symptoms and triggers better, which could help improve future treatments.
LondonAges 18 years+ - 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+ - 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 - NCT04419870Recruiting
Studying infections and immune responses in mitochondrial disease
This study looks at what happens in the body when someone with mitochondrial disease gets a sudden (acute) infection, and how the immune system and metabolism respond. Results may help doctors better recognize and manage infections in people with mitochondrial disease.
Bethesda, MarylandAges 2 months–115 years - NCT07051967Recruiting
Comparing recovery after ICU for pregnant and non-pregnant COVID-19 patients
This study looks at how COVID-19 and respiratory failure affect recovery after intensive care. It compares pregnant patients to non-pregnant patients to learn more about the long-term effects.
BerlinAges 18 years+ - NCT04448145Recruiting
Study why COVID lasts after recovery
This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
New York, New YorkAges 7 years+ - NCT05866952Recruiting
Breathing and blood-flow testing in long-COVID symptoms
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Boston, MassachusettsAges 18–99 - NCT06996834Recruiting
Comparing breathing support methods for pneumonia-related breathing failure
This trial tests two noninvasive breathing support methods (NIV and HVNI) for people with pneumonia who are having trouble breathing. The goal is to see which method works better to help you avoid needing a breathing tube.

Common questions
- Are there clinical trials for acute respiratory infection?
- Yes. Clin2 currently lists 100 recruiting acute 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 acute 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 acute 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.
