Covid19 Clinical Trial
Official title:
Imaging Immune Activation in COVID-19
This is a single center, single arm exploratory imaging study involving up to two intravenous microdoses of [18F]F-AraG (the second tracer dose is optional) followed by whole-body PET-CT imaging in participants with convalescent COVID-19. Up to 20 participants will be enrolled over an accrual period of approximately 24 months. Each participant will undergo one PET-CT scan following 50 +/- 10 minutes uptake following a single bolus injection of [18F]F-AraG in order to determine the tissue distribution of tracer in pariticpants with recent SARS-CoV-2 infection. A second optional [18F]F-AraG dose and PET-CT will be offered approximately 4 months following the initial imaging time point.
This is a single center exploratory imaging study involving up to two intravenous microdoses of [18F]F-AraG (the second tracer dose is optional) followed by whole-body PET-CT imaging in participants 18 years of age and older with recent SARS-CoV-2 diagnosis and COVID-19 at least 14 days following onset of symptoms. The primary objective is to determine the anatomical distribution of [18F]F-AraG in participant with convalescent COVID-19 approximately 4 weeks and 5 months (optional, 4 months following first PET imaging visit) following onset of symptoms (N = 20). Tracer activity will also be compared with sex and age-matched uninfected historical control participants enrolled in prior studies. Up to 20 participants will be enrolled in this study who will be identified in the UCSF LIINC longitudinal COVID-19 cohort study. Each participant will undergo one PET-CT scan following 50 +/- 10 minutes uptake following a single bolus injection of [18F]F-AraG. A second optional [18F]F-AraG dose and PET-CT will be offered approximately 4 months following the initial imaging time point. ;
