Individual considerations

Key practical issues The panel inferred that most fully informed individuals with non-severe illness would not want to receive corticosteroids, but many could want to consider this intervention through shared decision-making with their treating physician. When treating patients with non-severe disease, even after 7 days of symptoms, the panel concluded that it was preferable to err on the side of no corticosteroids Values and preferences Corticosteroids Usual supportive care In order to help guarantee access to therapy for severe or critical covid-19 patients, it is reasonable to avoid administering corticosteroids to patients who are less likely to derive benefit No additional practical issues

Conditions for use of treatment

IL-6 receptor blockers and baricitinib are also recommended, and may be administered in combination with corticosteroids. The incremental survival benefit afforded by baricitinib exists even among patients also treated with IL-6 receptor blockers and baricitinib Caution is advised when considering combinations in patients with an increased risk of opportunistic infections Consider combining medications in a stepwise fashion in patients who are deteriorating

Individual considerations

Key practical issues The panel inferred that all or almost all fully informed patients with severe or critical covid-19 would choose to take corticosteroids. In considering potential contraindications, clinicians must determine if they warrant depriving a patient from a potentially lifesaving treatment Values and preferences Corticosteroids Usual supportive care Absolute contraindications for 7 to 10 day courses of corticosteroid treatment are rare No clear differences in efficacy or adverse events between different corticosteroids Recommended regimens are available globally, and relatively inexpensive No additional practical issues

Individual considerations

Key practical issues The benefit of IL-6 receptor blockers on mortality was deemed of critical importance to patients, despite the small magnitude of effect and the very low certainty around serious adverse events. A majority of the panel inferred that almost all well informed patients would want to receive IL-6 receptor blockers Values and preferences IL-6 receptor blockers Usual supportive care Caution is advised when considering the use of tocilizumab in patients with a history of recurring or chronic infections All patients should be monitored for signs and symptoms of infection No additional practical issues

Values and preferences Molnupiravir Usual supportive care Patients should receive molnupiravir as soon as possible after onset of symptoms, ideally within 5 days from symptom onset Use of molnupiravir should be accompanied by mitigation strategies such as avoiding the drug in younger adults, children and pregnant patients, active pharmacovigilance programmes, and monitoring viral polymerase and spike sequences Nirmatrelvir/ritonavir and remdesivir both generally represent superior choices to molnupiravir. This is because of a greater reduction in risk of hospital admission in patients at high risk of admission with both drugs, and because of safety concerns with molnupiravir Longer term harms of molnupiravir remain unknown in the absence of clinical evidence, both for individual patients and at the population level No additional practical issues

Individual considerations

Key practical issues The panel inferred that the majority of well-informed patients with critical covid-19 would not want to receive remdesivir owing to little or no impact on important outcomes including mortality and need for invasive mechanical ventilation Values and preferences Remdesivir Usual supportive care Administration via intravenous infusion Optimal timing, duration and dosing remain unclear May be relatively costly, and there may be limited availability Not a significant inducer or inhibitor of CYP enzymes but should be monitored when co-administrated with strong inducers or inhibitors No additional practical issues Caution with significant liver or renal disease

VV116

No suggested regimen
Recommendation 1Supportive careVV116orPatients with covid-19at any severityWe recommend not using VV116, except inthe context of a clinical trialStrongAll or nearly all informed people would likelywant the intervention to the left. Benefitswould outweigh harms for almost everyoneWeakMost people would likely want the interventionto the left. Benefits would outweigh harms forthe majority, but not for everyoneWeakMost people would likely want the interventionto the right. Benefits would outweigh harmsfor the majority, but not for everyoneStrongAll or nearly all informed people would likelywant the intervention to the right. Benefitswould outweigh harms for almost everyone

Rationale

When formulating this recommendation, the panel emphasised the high degree ofuncertainty in critical outcomes including mortality and hospital admission. Thepanel was informed by only a single randomised controlled trial comparing VV116to nirmatrelvir and ritonavir, as opposed to standard of care or placebo

Individual considerations

Key practical issues Most patients would decline convalescent plasma given the lack of benefit in any important outcomes. Use could be considered as part of a clinical trial Values and preferences Convalescent plasma Usual supportive care Identification and recruitment of potential donors Collection of plasma Storage and distribution of plasma Infusion of convalescent plasma into recipients No additional practical issues

Evidence profile

Favours supportive careFavours colchicineNo important differenceThe panel found that this difference was not important for most patients,because the intervention effects were negligible and/or very imprecise, forexample confidence intervals that include both important benefit and harm
