Protectin D1 (PD1)

In vitro and mouse studies suggest PD1 could help treat influenza. In normal lung epithelial cells infected with influenza A virus, a lipid screen identified the lipid mediator PD1 as a suppressor of influenza replication. In mice, i.v. treatment with PD1 48 hours after infection increased survival compared with vehicle treatment. In the mouse model, PD1 plus the neuraminidase (NEU1; SIAL1) inhibitor peramivir led to 100% survival. Next steps could include testing PD1 in different animal models of influenza virus infection.
BioCryst Pharmaceuticals Inc. discontinued a Phase III trial of peramivir in November 2012 for futility following an interim analysis.
