Brief Summary:

This is a randomized, double blind, multi-center study to evaluate the effects of tocilizumab compared to placebo on patient outcomes in participants with confirmed SARS-CoV-2 infection and evidence of systemic inflammation.

The aim of this study is to test the effect of Tocilizumab on multi-organ dysfunction in a phase 3 randomized controlled trial among hospitalized patients with COVID-19 infection.

Specifically, as compared to placebo, we will test whether tocilizumab is associated with a reduction in multi-organ dysfunction among hospitalized COVID-19 adult patients with elevated inflammatory measures. Multi-organ dysfunction will be measured as the incidence of the following composite endpoint (mechanical ventilation, renal replacement therapy, mechanical support, need for inotropes or vasopressors, liver dysfunction (increased bilirubin), and all-cause mortality). We will also assess multiple pre-specified secondary (exploratory) endpoints and safety endpoints.

We hypothesize that, as compared to placebo, tocilizumab will reduce transfer to the ICU, need for mechanical ventilation, increase rates of hospital discharge in patients diagnosed with severe COVID-19 infection and evidence of exaggerated inflammatory response.

SARS-CoV 2 Drug: Tocilizumab Drug: Placebos Phase 3

Detailed Description:

As of April 3, 2020, COVID-19 has been confirmed in over 1 million people worldwide, with an estimated symptomatic case fatality ratio of around 1.4%. Currently without an effective treatment for SARS-CoV-2 there is an urgent need for effective treatment to curtail the rate of respiratory failure, the leading cause of mortality in COVID-19 disease. Moreover, with increasing numbers of patients requiring intensive unit level care and mechanical ventilation, nations are already having to triage patients for ventilatory support due to limited resources and healthcare systems around the world being stretched to the point of collapse, highlighting the importance of identifying interventions that could prevent the development of respiratory failure for these patients.

The disease course of COVID-19 includes an incubation period, an acute viral phase that most commonly presents with flu-like symptoms that in some individuals progresses to a severe hyperinflammatory phase marked by acute respiratory distress syndrome (ARDS) and hypoxemic respiratory failure.Though there is spectrum of clinical course, many progress to the hyperinflammatory phase around day seven of symptoms, often requiring intensive care unit (ICU) level care and mechanical ventilation. Accumulating evidence suggests that the pathophysiology underlying this profound decline is a severe inflammatory response as demonstrated by multi organ system dysfunction akin to cytokine release syndrome (CRS)/macrophage activation syndrome (MAS).CRS/MAS is a systemic hyperinflammatory syndrome on a spectrum with secondary hemophagocytic lymphohistiocytosis (sHLH), typically characterized by multiorgan failure that is often triggered by viral infections in the setting of excessive immune activation, typically with marked hyperferritinemia.Postmortem assessment of patients with COVID-19 have demonstrated pathologic findings consistent with MAS such as mono/lymphocytic infiltrates within the lung parenchyma with associated edema and alveolar congestion, splenic necrosis with macrophage proliferation and hemophagocytosis, as well as a lymphocyte/histiocyte predominate infiltrate of portal vasculature accompanying liver necrosis and sinusoidal congestion.Cytokine profiling of patients with MAS/sHLH overlaps with that seen in patients with severe COVID-19 and includes elevated levels of IL-1, IL-2, IL-7, IL-6, G-CSF, MCP- 1, and TNF-α as well as elevated D-dimer, C-reactive protein, LDH and troponins.Moreover, preliminary data from a non-randomized series of COVID-19 patients with "severe or critical COVID-19" from China who were treated with tocilizumab (in addition to standard therapies) showed they had dramatic improvement in fever, arterial oxygen saturation and inflammatory markers within the first 24-hours following administration.

Taken together, these data strongly suggest an immunologic link between COVID-19 and immune dysregulation resulting in MAS. Clinical trials are already underway studying the role of immunomodulatory therapy including modulation of IL-1 and IL-6 and downstream pathways in the setting of CAR-T induced MAS (NCT04150913, NCT04071366) and agents such anakinra and tocilizumab have been used in this context with promising results and good safety profiles. There is an urgent and dire need to study the therapeutic role for immunomodulatory therapy in COVID-19 disease to both halt disease progression in patients at an individual level and prevent the inevitable saturation of healthcare resources at a systems level, to which end there are numerous ongoing international trials to expand these efforts into the setting of COVID-19 infection (ChiCTR2000029765, NCT04324021, TOCOVID-19). Based on the MGH experience thus far with COVID-19, including over 200 patients to date, the need for mechanical ventilation has been approximately 30%. With the upcoming surge anticipated between April 17th and 21st we expect the need for hundreds of additional ICU beds. Investigators propose a trial of IL-6 receptor blockade with tocilizumab given early in disease course to try to prevent progression of COVID-19.

Primary Outcome Measures :
  1. Mechanical Ventilation or Death [ Time Frame: 28 days ]
    Time from administration of the investigational agent (or placebo) to requiring mechanical ventilation and intubation, or death for subjects who die prior to intubation. The percentages of patients who have been intubated or died as of day 14 and day 28 are estimated from the Kaplan-Meier curve.


Secondary Outcome Measures :
  1. Clinical Worsening on Ordinal Scale [ Time Frame: 28 days ]

    Time from administration of the investigational medication (or placebo) to at least one point worsening on the clinical improvement scale for subjects requiring supplemental oxygen (score >= 3) at baseline, or at least two point worsening otherwise (score = 2 at baseline). The percentages of patients who have worsened as of day 14 and day 28 are estimated from the Kaplan-Meier curve.

    Ordinal Scale

    1. Discharged
    2. Non-ICU hospital ward not requiring supplemental oxygen
    3. Non-ICU hospital ward requiring supplemental oxygen
    4. ICU or non-ICU hospital ward, requiring non-invasive ventilation or high-flow oxygen
    5. ICU, requiring intubation and mechanical ventilation
    6. ICU, requiring ECMO or mechanical ventilation and additional organ support
    7. Death

  2. Discontinuation of Supplemental Oxygen Among Patients Receiving it at Baseline [ Time Frame: 28 days ]
    Time from administration of the investigational agent (or placebo) to absence of the need for supplemental oxygen among those who require at least supplemental oxygen at baseline. The percentages of patients who have discontinued supplemental oxygen as of day 14 and day 28 are estimated from the Kaplan-Meier curve.


Other Outcome Measures:
  1. Duration of Supplemental Oxygen [ Time Frame: 28 days ]
    Time from initiation of supplemental oxygen to end of supplemental oxygen use during 28-day study follow-up period. We includes all subjects in the analysis by assigning all subjects who did not receive supplemental oxygen a value of 0. Subjects who died prior to discontinuation of supplemental oxygen were given a value of the number of days from when supplemental oxygen began until the end of the follow-up period.

  2. Duration of Mechanical Ventilation [ Time Frame: 28 days ]
    Time from initiation of mechanical ventilation to end of mechanical ventilation during 28-day study follow-up period, among patients who received mechanical ventilation. Event times of patients who died without discontinuation of mechanical ventilation were censored at 28 days. Median and inter-quartile range (IQR) were estimated using Kaplan-Meier curves. The upper limit for the IQR was not reached for both arms and entered as 28 in the outcome measure data table.

  3. Mortality [ Time Frame: 28 days ]
    Time from administration of the investigational agent (or placebo) to death. The percentage of patients who have died as of day 14 and day 28 are estimated from the Kaplan-Meier curve.

  4. ICU Admission or Death Among Those Not in the ICU at the Time of Administration of Investigational Agent (or Placebo) [ Time Frame: 28 days ]
    The percentage of subjects requiring ICU admission between baseline and 28 days is calculated by dividing the number of subjects requiring ICU admission over their hospitalization by the number of evaluable subjects (i.e., the number of subjects not in the ICU at the time of investigational treatment administration).

  5. Hospital Discharge [ Time Frame: 28 days ]
    Time from administration of the investigational medication (or placebo) to initial hospital discharge. Event times for patient who die are censored at day 29 to indicate that they never left the hospital during the follow-up period. The percentages of patients who were discharged as of day 14 and day 28 are estimated from the Kaplan-Meier curve.

  6. Clinical Improvement on Ordinal Scale [ Time Frame: 28 days ]

    Time to first improvement from administration of the investigational agent (or placebo) of at least 2 points (or the maximum amount) on the ordinal scale. Event times for patients who died prior to reaching this endpoint are censored at 29 days.

    Ordinal Scale

    1. Discharged
    2. Non-ICU hospital ward not requiring supplemental oxygen
    3. Non-ICU hospital ward requiring supplemental oxygen
    4. ICU or non-ICU hospital ward, requiring non-invasive ventilation or high-flow oxygen
    5. ICU, requiring intubation and mechanical ventilation
    6. ICU, requiring ECMO or mechanical ventilation and additional organ support
    7. Death
