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

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

Re: A living WHO guideline on drugs for covid-19

COVID-19 convalescent plasma should be further investigated!

Dear Editor,
on December 7th, WHO updated its living guideline on COVID-19 therapeutics, including convalescent plasma (CCP). This led to their recommendation against the use of CCP for COVID-19 patients, adding that it should only be used within clinical trials for severely and critically ill COVID-19 patients. In addition to their recommendation, WHO has stated that even though the evidence surrounding CCP’s benefit for severely ill patients is uncertain, they do recommend that trials focusing on subgroups of severe and critically ill patients should continue.

As the SUPPORT-E Consortium* we wish to respond to these recommendations.

In line with the recommendations from WHO, we agree that there is no firm evidence that CCP is a beneficial therapeutic treatment for COVID-19 patients, but we firmly believe that, given the rate of SARS-CoV-2 infection in Europe, as well as the existing therapeutic means and treatments, CCP is still worth investigating, in particular within specific patient groups.

There is no evidence that randomized clinical trials should focus only on severely ill COVID-19 patients: in fact the strongest data suggest efficacy of CCP in early intervention [1-3] among seronegative patients and immunosuppressed patients [4;5] Also, a significant antibody dose response has been reported [3;6-8]. A large number of earlier trials relied on “low titre” CCP, this is very different to CCP currently collected from vaccinated convalescent donors that have ten times higher titres, and broad “cross-variants” viral neutralization [9-12].

Moreover, the polyclonal antibody content of convalescent plasma could make this product an ideal source for hyperimmune immunoglobulin preparation, which require pooling large numbers of units of donor plasma, so standardizing the dose of high titre polyclonal specific antibodies. Although studies pertaining to the use of hyperimmune globulin have yet to be published, it is clear that CCP availability is a prerequisite in case of need for specific Ig preparation.

Other treatment options, notably recombinant monoclonal antibodies (MoAb) are not always available, especially in low and middle-income countries. These are expensive and prone to potential reduced efficacy against variants of concern.

The recent introduction of the Omicron variant with a high number of mutations in the Spike protein lead to viral escape and challenge existing MoAb [13]. Conversely, CCP collected among recently infected donors would contain Ig produced after infection with current variants. Additionally, this treatment would also be available in low-income countries.

WHO guidance does not present evidence against the use of CCP in people who do not have severe COVID-19 [14]. For non-severe COVID-19 it is based inter alia on the RECOVERY trial [15] which only provides good evidence for severely or critically ill patients, or on the PLACID trial which assessed CCP with low to undetectable levels of anti-SARS-CoV-2 antibodies to those randomised to receive convalescent plasma [16]. Among the participants, 99% were enrolled from inpatient settings [14], i.e., the significant subgroup of non-hospitalized, vulnerable patients at risk of hospitalization were not adequately represented in this analysis. Positive signals of CCP efficacy were detected in subgroup analyses of some negative RCTs. For instance, in patients with immunodeficiency enrolled in the REMAP-CAP trial [17], or in patients with milder COVID-19 in the recently published TSUNAMI trial [18]. The WHO provides recommendations for the whole spectrum of COVID-19 disease, while the available evidence is limited. Knowledge gaps must be clearly identified and investigated in further trials, e.g., very early treatment in non-hospitalized patients, immunocompromised patients, antibody-negative patients.

WHO latest guidance on CCP also refers to potential harm of transfusion, whilst also stating that there is no evidence of an increase of risks of transfusion-associated complications. The SUPPORT-E Consortium is therefore questioning the three-times repeated assertion of CCP associated to transfusion harm and its evidence. A recent meta-analysis on 30 randomized and non-randomized trials documented the safety of CCP compared to standard therapy, even when thromboembolic complications were considered [19].

On the mobilization of resources dedicated to collect CCP, it should be noted that there is no waste or overuse of human resources. Research on CCP allowed blood establishments to increase their collection of plasma that, if not used for treating COVID-19 patients, is nevertheless kept and stored for future usage, for regular (non-COVID-19 related) transfusion or to produce plasma derived medicinal products (PDMPs).

The SUPPORT-E Consortium notes that the WHO guidance on CCP highlights high cost and limited availability, when for monoclonals (or antivirals) these logistic arguments are not emphasized in the same manner. In particular, the conclusion drawn from these practical issues is peculiar since it is presented as if the above practical issues contribute to the recommendation not to administer CCP while it leads to recommending monoclonals – despite the even higher cost and very limited availability, and the increased risk that monoclonals lose their activity against newly emerging variants.

In Europe, a big part of research on CCP is based on data collected and shared through the SUPPORT-E EU CCP database [20] containing data on 153,000 CCP donations; analysing the data and drawing conclusions from them is ongoing and results will be presented at the end of the project. It therefore seems premature to draw firm conclusions on the use of CCP, at this stage.

We believe that research on CCP use should only stop or be discouraged in either of two situations: (i) when a therapy is showing harm to the patients or (ii) when the question explored is no longer pertinent or worth exploring. We do not think that this is the case.

We further wish to underline the importance of the scientific community to keep exploring the potential of CCP. It still is a promising, inexpensive, and well tolerated therapy that actively involves communities to care for those who suffer from acute infection by those who have recovered thus valuing the contribution of donors in this fight against a pandemic.

The SUPPORT-E Consortium is very much grateful for the ongoing financial support of the European Commission funding this research.
