COVID-19 therapy: What works? What doesn’t? And what’s on the horizon?
Here is the latest evidence on the efficacy and safety of treatments that are FDA approved or authorized, in clinical trials, or not recommended to combat COVID-19.
PRACTICE RECOMMENDATIONS
› Use antivirals (eg, molnupiravir, nirmatrelvir packaged with ritonavir [Paxlovid], and remdesivir) and monoclonal antibody agents (eg, bebtelovimab) effective against the circulating Omicron variant, to treat symptoms of mild-to-moderate COVID-19 illness. C
› Treat severely ill hospitalized COVID-19 patients who require supplemental oxygen with dexamethasone, alone or in combination with remdesivir, to produce better outcomes. B
› Consider administering baricitinib or tocilizumab, in addition to dexamethasone with or without remdesivir, to COVID-19 patients with rapidly increasing oxygen requirements. B
Strength of recommendation (SOR)
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
Summing up
With a growing need for effective and readily available COVID-19 treatments, there are an unprecedented number of clinical trials in process. Besides antivirals, immunomodulators, and antibody therapies, some novel mechanisms being tested include Janus kinase inhibitors, IL-6-receptor blockers, and drugs that target adult respiratory distress syndrome and cytokine release.
Once larger trials are completed, we can expect stronger evidence of potential treatment options and of safety and efficacy in children, pregnant women, and vulnerable populations. During the pandemic, the FDA’s EUA program has brought emerging treatments rapidly to clinicians; nevertheless, high-quality evidence, with thorough peer review, remains critical to inform COVID-19 treatment guidelines.
