About

This is a cohort study of COVID-19 patients with hyperinflammation. It aims to determine the impact of adjunctive Tocilizumab (TCZ) to standard of care on the reduction of hyperinflammation-related mortality in COVID-19. Patients with COVID-19 are at high risk of life-threatening hyperinflammation and death. One in three COVID-19 patients admitted to ICU was found to develop life-threatening hyperinflammation. The risk of death when untreated is estimated to be 50-80%.

Full description

The novel coronavirus, SARS-Cov2/COVID-19, emerged in late 2019 in Wuhan, China. Quickly, SARS-CoV2 spread to all corners of the globe. In March 2020, The World Health Organization (WHO) declared SARS-CoV2/COVID-19 a pandemic. Individuals infected with SARS-CoV2 have a varied clinical presentation, ranging from asymptomatic or mild respiratory symptoms to severe involvement of the lower respiratory tract, with patients requiring mechanical ventilation. A particular point of interest is how the overall severity and clinical outcomes of COVID-19 patients may be associated with the excessive production of pro-inflammatory cytokines, or hyperinflammation, leading to acute respiratory distress syndrome. This state of hyperinflammation may be associated with increased mortality in COVID-19 patients. Tocilizumab, an Interleukin-6 antagonist, may help treat COVID-19 associated hyperinflammation. This is a nested interventional cohort study of COVID-19 patients with hyperinflammation. It aims to determine the impact of adjunctive Tocilizumab (TCZ) to standard of care on the reduction of hyperinflammation-related mortality in COVID-19. Patients with COVID-19 are at high risk of life-threatening hyperinflammation and death. One in three COVID-19 patients admitted to ICU was found to develop life-threatening hyperinflammation. The risk of death when untreated is estimated to be 50-80%. TCZ treatment may reduce mortality. Primary objective: To establish that tocilizumab, in addition to standard of care, reduces the 30-day mortality from hyperinflammation in COVID-19 disease significantly compared to no anti-interleukin therapy plus standard of care. Secondary objectives: To evaluate the addition of tocilizumab therapy to standard of care on a number of secondary outcomes.

30 participants in 2 patient groups

Tocilizumab Arm
Experimental group
Description:
Tocilizumab 8 mg/kg IV up to a maximum of 800 mg with possible repetition of the same dosage within 28 hours (the optional second dose after 12 hours but before 28 hours following the first dose), based on the clinical judgement of the attending physician in consultation with the COVID-inflammation team.
Treatment:
Biological: Tocilizumab
No Intervention Arm
No Intervention group
Description:
No intervention arm patients will be identified from medical records, as being COVID-19 positive patients with hyperinflammation who did not receive any interleukin antagonist treatment.
