Seattle, WashingtonAges 18 years+ - NCT04545242RecruitingPhase 4
Dexamethasone for severe lung failure from infections on ventilators
This trial studies whether dexamethasone (a steroid medicine) improves outcomes in adults who have sudden, severe breathing failure caused by an infection while they are on a breathing machine. It may help reduce inflammation in the lungs during critical illness.
Terrassa, BarcelonaAges 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.
Newport Beach, CaliforniaAges 18 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+ - NCT05814237Recruiting
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+ - NCT05947955RecruitingPhase 2
Study drug for infection-related lung failure in adults
This Phase 2 trial tests Rhu-pGSN in adults with acute respiratory distress syndrome (ARDS) caused by an infection. If you qualify, the study may help determine whether the drug improves outcomes in this short-term, life-threatening lung condition.
