Abstract

Insights

Developing effective filovirus therapeutics, including small molecules and antibodies, is crucial due to high fatality rates. Research focuses on pan-filovirus treatments and prophylactic strategies for diseases like Ebola and Marburg virus infections.

Area of Science:

  • Virology
  • Infectious Diseases
  • Drug Development

Background:

  • Filoviruses, including Ebola and Marburg viruses, are dangerous RNA viruses causing hemorrhagic fevers with high mortality rates.
  • The 2013-2016 Ebola epidemic highlighted the global threat and accelerated the need for effective treatments.
  • Despite progress, limited therapeutic options exist for the six known human-pathogenic filoviruses.

Purpose of the Study:

  • To review the identification, testing, and development of filovirus therapeutics.
  • To summarize promising therapeutic strategies based on peer-reviewed literature since 1967.
  • To emphasize treatments showing efficacy in preclinical in vivo studies.

Main Methods:

  • Literature review of scientific publications on filovirus therapeutics.
  • Discussion of various therapeutic modalities including small molecules, antibodies, and host-targeted approaches.
  • Focus on studies demonstrating promise in nonhuman primate models.

Main Results:

  • Two monoclonal antibody regimens are FDA-approved for Ebola virus treatment.
  • Preclinical data suggest antibody-based therapies are effective against other filoviruses.
  • Significant advancements are noted in small-molecule antivirals and host-targeted strategies.

Conclusions:

  • Pan-filovirus therapeutics, such as broad-spectrum small molecules and antibody cocktails, are essential.
  • Development of cross-reactive antibodies is a key area for future research.
  • Consideration of filovirus therapeutics for prophylaxis and chronic infection management is warranted.
