Официальное название
Advanced Imaging to Assess the Effect of Immunosuppression on Progressive Lung Fibrosis in Participants With Non-Idiopathic Pulmonary Fibrosis Interstitial Lung Disease
Обзор
The purpose of this study is to investigate how immunosuppression treatment affects measurements of active collagen deposition using \[68Ga\]CBP8 positron emission tomography (PET) and tissue injury using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in individuals with non-idiopathic pulmonary fibrosis interstitial lung disease (non-IPF ILD).
Подробное описание
15 different subjects with non-IPF ILD starting immunosuppression treatment for their underlying ILD will be enrolled. Participants will undergo \[68Ga\]CBP8 PET and DCE-MRI prior to and 12 weeks after treatment initiation to determine the effects of immunosuppressive treatment on PET measurements of collagen deposition and selected DCE-MRI-derived measurements.
Вмешательства
- Препарат [68Ga]CBP8
Participants will receive a single intravenous injection of up to 350 MBq of \[68Ga\]CBP8 - Препарат Gadoterate Meglumine
Participants will receive a single intravenous injection of 0.05 mmol/kg gadoterate meglumine during DCE-MRI
