Advanced Imaging to Assess the Effect of Immunosuppression on Progressive Lung Fibrosis in Participants With Non-Idiopathic Pulmonary Fibrosis Interstitial Lung Disease
Peter Caravan
Summary
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).
Description
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.

Inclusion Criteria: 1. Age 18-80 with a diagnosis of chronic hypersensitivity pneumonitis, connective tissue-associated ILD (due to rheumatoid arthritis, systemic sclerosis, mixed connective tissue disease), or undifferentiated ILD. 2. Starting immunosuppression treatment with mycophenolate mofetil, mycophenolate sodium, and / or prednisone for clinically indicated non-IPF ILD treatment. 3. Pulmonary fibrosis, defined as honeycombing, traction bronchiectasis, or reticular opacities on high-resolution computed tomography (HRCT) performed within 1 year to or at Visit 1. 4. Forced vital capacity…
