This clinical trial is focused on studying a condition known as Acute Respiratory Distress Syndrome (ARDS), specifically in cases where the condition does not improve over time, referred to as non-resolving ARDS. The study will use a special imaging technique called PET/CT to observe the activity of certain cells in the lungs that are involved in the formation of fibrous tissue, which can affect breathing.
The treatment being studied involves a solution for injection called [68Ga]FAPI-46. This is a chemical substance that helps to highlight the activity of fibrogenic cells in the lungs when viewed through the PET/CT scan. The purpose of the study is to understand how the activity of these cells relates to the patient’s recovery, including their survival after 28 days, the number of days they can breathe without a ventilator, and the length of their stay in the intensive care unit (ICU).
During the study, patients with non-resolving ARDS who are on mechanical ventilation will receive the [68Ga]FAPI-46 injection. The PET/CT scan will then be used to visualize the activity of the fibrogenic cells in their lungs. The study aims to gather information on how this activity is connected to various health outcomes, such as the patient’s respiratory condition and certain markers in their blood that indicate inflammation. The study will also evaluate the PET/CT procedure itself to ensure it is safe and effective for patients.
