Tocilizumab in Coronavirus-19 Positive Patients

July 20, 2020 updated by: University of Calgary

A Nested Interventional Cohort Study to Assess the Efficacy and Safety of Adjunctive Humanized Monoclonal Interleukin-6 Receptor Blocker Tocilizumab (TCZ) Therapy to Standard of Care for the Reduction of Hyperinflammation Related Mortality in SARS-Cov2 Positive Patients

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%.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
