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 - 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+ - NCT06066502RecruitingPhase 3
Precision ventilation for ARDS
This study tests whether a customized breathing machine approach ("precision ventilation") is better than usual care for patients with ARDS. The goal is to improve oxygen levels and recovery while avoiding lung damage.
Tucson, ArizonaAges 18 years+ - NCT07573150Recruiting
Pupil Measurements to Predict Breathing Problems After Surgery in Children
This study tests whether measuring how a child's pupils (the dark circles in the eyes) respond to light can predict which children might have breathing problems after receiving pain medication during tonsil surgery. The goal is to help doctors catch and prevent serious breathing issues before they happen.
San Francisco, CaliforniaAges 3–17 - 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+ - NCT07578389Enrolling by invitation
Testing smartwatch accuracy for measuring breathing rate
This study tests whether a smartwatch can accurately measure how fast you breathe. Researchers will compare the smartwatch's readings to medical-grade equipment to see if smartwatches could be useful for health monitoring.
KladnoAges 18 years+ - NCT07217197Enrolling by invitation
A monitor to detect breathing problems after surgery
This trial tests a new respiratory monitoring system to see if it can detect and predict opioid-induced respiratory depression (OIRD) — when pain medicines slow your breathing too much — in patients recovering from surgery. The monitor uses a face mask, nasal cannula, and small sensors to track breathing continuously, so that doctors can step in early if there is a problem.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06938217Enrolling by invitation
Low-flow ECMO for adults with severe breathing failure
This study tests whether a gentler, low-blood-flow version of ECMO (a machine that helps oxygenate blood outside the body) is safe and effective for adults with very severe breathing failure. It is for patients who are already on a breathing machine and have very low oxygen levels despite that support.
San Antonio, TexasAges 18–65 - NCT06916104Enrolling by invitation
Allergies and biotherapy in severe asthma
This study looks at whether having a respiratory allergy affects how well biotherapy works for people with severe asthma. It includes adults already on biotherapy and followed at Poitiers University Hospital.
PoitiersAges 18 years+ - 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+ - NCT06598709Enrolling by invitation
International study on breathing tube removal in ARDS
This study looks at how doctors safely remove breathing tubes from patients with lung injury (ARDS). It aims to find ways to improve decisions about when to take the tube out.
HiroshimaAges 16 years+ - NCT05462600Enrolling by invitation
Breathing monitoring test in non-smokers
This study measures how you breathe and how well oxygen and carbon dioxide move in and out of your lungs. It’s mainly a monitoring study to help researchers understand breathing patterns during a breathing test.
La Jolla, CaliforniaAges 18 years+ - NCT07730034Recruiting
Early physical therapy after heart surgery to prevent breathing problems
This trial tests whether starting physical therapy soon after planned heart surgery can help prevent breathing complications. It is for adults who are having a first-time coronary artery bypass grafting (CABG) and meet specific health criteria.
ZagrebAges 18–80 - NCT07214571RecruitingPhase 2
Study of S-337395 for RSV in high-risk adults
This trial tests an experimental drug called S-337395 for adults with RSV who are not in the hospital but are at high risk for severe illness. It aims to see if the drug can help prevent symptoms from getting worse.
Los Angeles, CaliforniaAges 18 years+ - NCT07086755RecruitingPhase 2/Phase 3
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+ - NCT06776783RecruitingPhase 3
Testing a new surfactant for breathing problems in premature babies
This study tests a new medicine called APC-0101, a type of surfactant, for premature babies with breathing problems (respiratory distress syndrome). It may help their lungs work better and reduce the need for more breathing support.
Little Rock, ArkansasAges 1 hour–1 day - NCT06758791Enrolling by invitation
Breathing, balance, and walking after stroke
This study looks at how breathing muscle function relates to balance and walking in people who have had a stroke. It may help find new ways to improve recovery.
Istanbul, BüyükçekmeceAges 18–80 - NCT07189078Recruiting
Comparing intubation methods for patients with low blood oxygen
This study tests two different ways to place a breathing tube in patients who are in intensive care with very low oxygen levels and need help breathing. The goal is to find which method is safer and works better for patients like you.
AngersAges 18 years+ - NCT05002478Recruiting
Prone positioning for very sick babies with lung distress
This trial tests whether turning very sick, ventilated infants onto their stomach (prone positioning) can improve breathing when they have severe lung distress from likely pneumonia or bronchiolitis. It may help your baby get better oxygen levels and recover faster, while doctors closely monitor safety.
ViennaAges Up to 1 year - NCT06851806Recruiting
Palivizumab study for children at high risk of severe RSV
This study tests a medication called palivizumab to help protect certain children from severe RSV (a common respiratory virus). It is for infants and young children with a higher chance of getting very sick from RSV, such as premature babies or those with certain heart or lung conditions.
HyderabadAges Any age - NCT05670093Recruiting
Testing pressure support to ease breathing muscle work
This trial looks at a breathing-support setting that may reduce the effort of your breathing muscles while you’re coming off a ventilator. It’s meant for people who have been on a breathing machine for more than 24 hours during the “weaning” phase.
