COVID-19 therapy: What works? What doesn’t? And what’s on the horizon?   

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.

Guidelines recommend against using dexamethasone and other systemic corticosteroids in COVID-19 outpatient settings.

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.
