An Industry Perspective on Dengue Drug Discovery and Development.

Abstract

Dengue is the most important mosquito-borne viral disease in the world, representing a major unmet medical need and a growing public health concern. The disease imposes a heavy burden to the affected individuals, to the health care systems, and to the economies of endemic countries. Vector control is the most widespread tool to curb dengue epidemics, but has been insufficient. Therefore, additional means such as vaccines and antivirals are required to aid in a coordinated response. The discovery and development of small molecule dengue virus inhibitors as a tool to prevent and/or treat dengue disease faces major hurdles in combining pan-serotypic efficacy, safety, and optimal drug-like properties. Moreover, the financial return of dengue drug projects may not compensate for the initial investment in research and development. This review article addresses the efforts undertaken to face the dengue epidemics, focusing on antiviral drug development. The dengue drug research and development process is described in detail and a dengue antiviral target product profile is proposed. The article discusses collaborations between the different players in the research field: government and government-sponsored organizations, pharmaceutical and biotechnology companies, academia, and non-profit and philanthropic organizations. Public-private partnerships are proposed as a model to boost dengue research and development towards an approved antiviral drug in the near future.
