ABSTRACT
Respiratory syncytial virus (RSV) causes respiratory disease and complications in infants, the elderly and the immunocompromised. While three vaccines and two prophylactic monoclonal antibodies are now available, only one antiviral, ribavirin, is currently approved for treatment. This review aims to summarize the current state of treatments directly targeting RSV. Two major viral processes are attractive for RSV-specific antiviral drug discovery and development as they play essential roles in the viral cycle the entry/fusion process carried out by the fusion protein and the replication/transcription process carried out by the polymerase complex constituted of the L, P, N and M2-1 proteins. For each viral target resistance mutations to small molecules of different chemotypes seem to delineate definite binding pockets in the fusion proteins and in the large proteins. Elucidating the mechanism of action of these inhibitors thus helps to understand how the fusion and polymerase complexes execute their functions. While many inhibitors have been studied, few are currently in clinical development for RSV treatment one is in phase III, three in phase II and two in phase I. Progression was halted for many others because of strategic decisions, low enrollment, safety, but also lack of efficacy. Lessons can be learnt from the halted programs to increase the success rate of the treatments currently in development.
