CTAG: Immune-modulating agents

Download the Position Statement

(V6.0 30 November 2020)

Key messages

  • A subset of patients with COVID-19 may experience an exaggerated hyperinflammatory response
  • COVID-19 associated hyperinflammation predominantly involves the lung however may progress to secondary haemophagocytic lymphohistocytosis (sHLH) which is a systemic and multi-organ condition with significant morbidity and mortality
  • CTAG strongly recommends systemic corticosteroids for patients who fit definitions of WHO-defined severe or critical COVID-19, or in patients who otherwise have a new oxygen requirement
  • CTAG also recommends not to use corticosteroid therapy in patients with WHO-defined non-severe COVID-19 (i.e. the absence of any signs of severe or critical COVID-19).
  • As far as possible, the use of investigative immunomodulatory medicines should be used in the context of a national priority clinical trial. This includes patients treated with remdesivir +/- corticosteroids
  • CTAG acknowledges the recent CAS (Central Alerting System) statement regarding off-label use of tocilizumab in adult patients admitted to the intensive care unit with COVID-19 pneumonia. Published data so far have not demonstrated consistent benefit of tocilizumab in hospitalised patients with COVID-19 outside of the intensive care unit. A recent press release from the REMAP-CAP trial indicated possible benefit in patients admitted to the intensive care unit. CTAG continues to encourage the recruitment of patients into randomised controlled trials, and we do not advocate the use of off-label tocilizumab until further information is made available from REMAP-CAP or other studies in this population.
  • Patients who meet diagnostic criteria for sHLH should be managed within established pathways, guided by a specialist familiar with hyperinflammation
  • IVIG for PIMS-TS should ideally be used within the context of the RECOVERY clinical trial
  • Advice on the appropriate use of remdesivir is available in the CTAG Antivirals position statement
  • Suspected side effects to medicines used in coronavirus treatment should be reported via the Yellow Card COVID-19 reporting site

Provenance

CTAG acts as a formal advisory group to the Royal College of Physicians and this position statement is endorsed by:

The CTAG Immunomodulators subgroup takes its membership from HLH Across Specialities Collaboration (HASC), a group already formed for management and research of HLH and have expanded remit to include hyper-inflammation associated with COVID-19.
