Overview
- A Nature Microbiology paper published Friday reported that oral GHP-88310 blocked both direct-contact and airborne spread of a measles-like virus (canine distemper virus) in a ferret model.
- GHP-88310 is a broad-spectrum orthoparamyxovirus polymerase inhibitor that acts by blocking the viral polymerase enzyme needed for viral replication.
- In the experiments, twice-daily prophylaxis prevented transmission in air contacts, once-daily prophylaxis produced complete survival with seroconversion, and therapeutic dosing shortened contagiousness by about five days and prevented fatal outcomes in treated contacts.
- The study was led by the Center for Translational Antiviral Research at Georgia State University, was funded by NIAID/NIH, and the investigators are preparing formal clinical trials while stressing that human safety and effectiveness have not yet been demonstrated.
- The finding arrives against a backdrop of measles resurgence in North America since 2025 and, if replicated in humans, could help limit outbreaks, shorten quarantines, and reduce social and economic disruption.
