Breathe Easy: This Chip Finds Promising COVID-19 Drug, But Watch Out for Side Effects!
This study used a human airway-on-a-chip to model viral infections and screen drugs, identifying amodiaquine as a potential COVID-19 treatment. This drug, and its metabolite, showed promising results in preventing and treating SARS-CoV-2 infection in hamsters, but further research is needed to fully evaluate its safety and effectiveness in humans due to potential side effects.
Possible Conflicts of Interest
D.E.I. is involved with and holds equity in Emulate, Inc, the company that provided the Organ Chip devices. D.E.I. and other authors also hold patents related to the technology.
Identified Weaknesses
Simplified model
The study uses a simplified model of the human airway, which may not fully capture the complexity of the in vivo environment. This could affect the generalizability of the findings to real-world clinical settings.
Focus on prophylaxis
The study primarily focuses on prophylactic treatment rather than therapeutic treatment, which limits its clinical applicability. While some therapeutic effects were observed, the focus on prevention may not fully address the needs of patients who are already infected with COVID-19.
Potential side effects of amodiaquine
While amodiaquine showed promising results in the hamster model, the drug has potential side effects, including liver damage and agranulocytosis, which need to be carefully considered when evaluating its potential use in humans. The study mentions this, but further investigations into the risk/benefit profile in humans is needed.
Rating Explanation
This study uses innovative "organ-on-a-chip" technology to model the human airway and screen for potential antiviral drugs, including for COVID-19. It successfully identified amodiaquine as a promising prophylactic and therapeutic candidate and validated the findings in a hamster model. The methodology is strong and addresses a critical need for faster drug development. The conflicts of interest related to the organ chip technology and the potential side effects of amodiaquine prevent a higher rating.
