Abstract:
The development of effective antiviral therapy for COVID-19 is critical for those awaiting vaccination, as well as for those who do not respond robustly to vaccination. This review summarizes 1 year of progress in the race to develop antiviral therapies for COVID-19, including research spanning preclinical and clinical drug development efforts, with an emphasis on antiviral compounds that are in clinical development or that are high priorities for clinical development. The review is divided into sections on compounds that inhibit SARS-CoV-2 enzymes, including its polymerase and proteases; compounds that inhibit virus entry, including monoclonal antibodies; interferons; and repurposed drugs that inhibit host processes required for SARS-CoV-2 replication. The review concludes with a summary of the lessons to be learned from SARS-CoV-2 drug development efforts and the challenges to continued progress.
Insights
Developing effective antiviral therapies for COVID-19 is crucial. This review covers one year of progress in preclinical and clinical drug development, focusing on compounds targeting SARS-CoV-2 replication.
Area of Science:
- Virology
- Pharmacology
- Infectious Diseases
Background:
- Effective antiviral therapy for COVID-19 remains critical, especially for unvaccinated individuals and those with suboptimal vaccine responses.
- The rapid emergence of SARS-CoV-2 necessitated urgent development of therapeutic interventions.
- A comprehensive understanding of antiviral drug development is essential for managing the ongoing pandemic.
Purpose of the Study:
- To summarize one year of progress in the development of antiviral therapies for COVID-19.
- To review preclinical and clinical research on antiviral compounds targeting SARS-CoV-2.
- To highlight compounds in or prioritized for clinical development.
Main Methods:
- Systematic review of preclinical and clinical research on COVID-19 antiviral therapies.
- Categorization of antiviral compounds based on their mechanism of action against SARS-CoV-2.
- Emphasis on compounds in clinical development or of high clinical priority.
Main Results:
- Progress has been made in developing antivirals targeting SARS-CoV-2 enzymes (polymerase, proteases).
- Inhibitors of virus entry, including monoclonal antibodies, have shown promise.
- Repurposed drugs and interferons are also being investigated for their antiviral effects.
- Research spans diverse strategies, including targeting viral replication and host-cell interactions.
Conclusions:
- Significant advancements have been achieved in COVID-19 antiviral drug development within one year.
- Lessons learned from SARS-CoV-2 drug development can inform future antiviral research.
