Georgia State University researchers reported that the oral polymerase inhibitor candidate GHP-88310 blocked both airborne and contact-mediated transmission in a ferret measles-like model. The Nature Microbiology paper described prophylactic and post-exposure dosing that prevented virus spread and reduced clinical symptoms. The study, led by the Plemper lab and reported by investigators including Carolin Lieber, built on earlier work describing GHP-88310’s broad-spectrum orthoparamyxovirus activity, shifting attention from treatment alone to outbreak containment. With US measles counts near post-elimination levels driven by waning vaccination, the data position GHP-88310 as a potential augmentation to ring vaccination strategies, if future translational and clinical evidence supports efficacy and dosing practicality.
