Check biomarkers during bronchoscopy in breathing and throat pre-cancer
This study looks at “biomarkers” (measurable signals in samples) taken during bronchoscopy or related procedures in people with severe airway pre-cancer or certain lung/throat cancers, and in healthy volunteers. The goal is to better understand what these biomarkers mean and how they might help with diagnosis, staging, or monitoring.
Aurora, ColoradoAges 21–90 - NCT05022264Recruiting
Remote monitoring test during clinic visits with vital signs
This study checks how well a new device can measure vital signs (like breathing and circulation) from patients during primary or secondary care visits. It also compares the device results with standard reference methods to see if it’s safe and reliable, without causing important delays in care.
UlricehamnAges 18 years+ - NCT06322719Recruiting
Comparing two blades for intubation in the ICU
This trial tests which blade (hyperangulated or Macintosh) works better when doctors use a video laryngoscope to place a breathing tube in intensive care patients. It may help improve how intubation is done in the ICU.
Santiago de Compostela, A CoruñaAges 18–90 - NCT06331364Recruiting
Treating lung infections with better antibiotic decisions in Sri Lanka
This study tests whether a new way of deciding when to use antibiotics helps patients with lower respiratory infections (like pneumonia or bronchitis) in Sri Lankan hospitals. If you were recently admitted with a new lung infection, you may be able to join.

- Yes. Clin2 currently lists 922 recruiting respiratory 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 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 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.
