The International multicenter FEnofibRate as a Metabolic INtervention for COVID-19 (FERMIN) trial is being executed. The aim of this trial is to assess the impact of fenofibrate (administered for 10 days) to improve clinical outcomes in patients with COVID-19, assessed at 30 days. However, given the accumulating evidence of chronic / long term sequelae of COVID-19, it is important to assess the long-term impact of this intervention in this patient population. The overarching goal of this substudy is to assess the impact of fenofibrate on key intermediate phenotypes of vascular, cardiac and pulmonary health. We also aim to address the impact of fenofibrate therapy (administered during the acute COVID-19 episode as part of the parent FERMIN trial) on long-term integrated cardiopulmonary function, persistent/chronic symptoms and quality of life. We will accomplish this via enrollment of previous FERMIN participants from the University of Pennsylvania, in an phenotyping study designed to assess vascular, cardiac and pulmonary status several months after the index episode of COVID-19. We will perform these assessments \~6 months after initial randomization, among 40 FERMIN trial participants enrolled at the University of Pennsylvania.
