Crizanlizumab for Treating COVID-19 Vasculopathy (CRITICAL)

November 3, 2021 updated by: Johns Hopkins University
The purpose of this trial is to test the efficacy and safety of crizanlizumab in patients hospitalized with COVID-19.

Conditions

Detailed Description

Infection with severe acute respiratory syndrome (SARS) coronavirus 2 (CoV-2) causes coronavirus disease 2019 (COVID-19). The clinical course of COVID-19 is variable, and some patients develop severe pneumonia, multi-organ failure, and shock.

Severe COVID-19 is characterized by a hyper-inflammatory and hyper-thrombotic state. We propose that this state is caused by viral injury of the vascular endothelium, leading to endothelial release of von Willebrand Factor (VWF) and P-selectin, which in turn drive thrombosis and vascular inflammation.

Crizanlizumab is a monoclonal antibody that targets P-selectin. Crizanlizumab can decrease inflammation by binding to P-selectin, blocking leucocyte and platelet adherence to the vessel wall.

We now plan to test the safety and efficacy of crizanlizumab in decreasing biomarkers of inflammation and thrombosis in a placebo-controlled, double-blind randomized clinical trial

Change in Clinical Status as Assessed by the World Health Organization (WHO) Ordinal Scale for Coronavirus Disease 2019 (COVID-19) Trials
Time Frame: Days 3, 7 and 14 after randomization

Change in the clinical status over 14 days as measured by an ordinal scale that is the first assessment of the clinical status on a given study day. The scale is as follows:

0 = Uninfected; no viral RNA detected

  1. = Ambulatory; asymptomatic; viral RNA detected
  2. = Ambulatory; symptomatic; independent
  3. = Ambulatory; symptomatic; assistance needed
  4. = Hospitalized; no oxygen therapy
  5. = Hospitalized; oxygen by mask or nasal prongs
  6. = Hospitalized; oxygen by non-invasive ventilation (NIV) or high flow
  7. = Hospitalized; intubation and mechanical ventilation, partial pressure of oxygen / fraction of inspired oxygen (pO2/FIO2) ≥ 150 or oxygen saturation / FIO2 (SpO2/FIO2) ≥ 200
  8. = Hospitalized; intubation and mechanical ventilation, pO2/FIO2 < 150 or SpO2/FIO2 < 200 or vasopressors
  9. = Hospitalized; intubation and mechanical ventilation, pO2/FIO2 < 150 or SpO2/FIO2 < 200 and vasopressors, dialysis, or extracorporeal membrane oxygenation (ECMO)
  10. = Dead
Days 3, 7 and 14 after randomization
Time to Hospital Discharge
Time Frame: Up to 30 days after randomization
