Invasive fungal infection (IFI) is a growing cause of morbidity and mortality in oncology and transplant patients.

View details for DOI 10.1126/scitranslmed.abm7853 Together, these results show that IgG-FcgammaR interactions are able to regulate inflammation in the lung and may define distinct lung activities associated with the IgG that are associated with severe COVID-19 and protection against infection with SARS-CoV-2. By contrast, vaccine-elicited IgG did not promote an inflammatory lung response. Afucosylated IgG immune complexes isolated from COVID-19 patients induced inflammatory cytokine production and robust infiltration of the lung by immune cells. To study the biology afucosylated IgG immune complexes, we developed an in vivo model that revealed that human IgG-Fc gamma receptor (FcgammaR) interactions could regulate inflammation in the lung. In contrast to the antibody structures that were associated with disease progression, antibodies that were elicited by mRNA SARS-CoV-2 vaccines were instead highly fucosylated and enriched in sialylation, both modifications that reduce the inflammatory potential of IgG. In two prospective cohorts, early non-neutralizing, afucosylated IgG antibodies specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were associated with progression from mild to more severe COVID-19. Stanford is currently not accepting patients for this trial.Ī damaging inflammatory response is implicated in the pathogenesis of severe coronavirus disease 2019 (COVID-19), but mechanisms contributing to this response are unclear. Least 24 hours after the ELAD Treatment Period is ended (end of Day 7 for Controls) and up toīoth End of Study Days 28 and 91 following Randomization. Points from End of Study Day 1 MELD score (for both the ELAD and Control groups) until at Progression is defined as death or the first observed increase of at least 5 Up to Study Day 91, and the proportion of progression-free survivors (PFS) up to Study DaysĢ8 and 91. Measured using the Model for End Stage Liver Disease (MELD)-based time to progression (TTP) Secondary objectives are to determine the proportion of survivors at Study Days 28 and 91.Įxploratory objectives are to evaluate the ability of ELAD to stabilize liver function, Through VTI-208 study termination (after the last surviving enrolled subject completes Study
