The ECLA PHRI COLCOVID Trial is a simple, pragmatic randomized open controlled trial to test the effects of colchicine on moderate/high-risk hospitalized COVID-19 patients with the aim of reducing mortality and/or new requirement for mechanical ventilation.
Various anti-viral treatments are being tested in clinical trials worldwide. The World Health Organization (WHO) launched a simple,pragmatic worldwide open-label trial to test Remdesivir, Lopinavir/Ritonavir, Interferon and Hydroxychloroquine or Chloroquine.The most important complication of COVID-19 severe cases is respiratory failure from severe acute respiratory syndrome (SARS), the leading cause of mortality. Accumulating evidence suggests that patients with severe COVID-19 might have a cytokine storm syndrome, a hyperinflammatory syndrome characterized by a fulminant and fatal hypercytokinemia and multiorgan failure.
The proposed pathophysiological mechanism of cytokine storm and inflammatory cascade activation is based on evidence collected primarily during the SARS-CoV and MERS-CoV epidemics (with a significant increase in IL1B, IL6, IL12, IFNγ, IP10, TNFα, IL15, and IL17 among others). The data collected during the pandemic with COVID-19 also shows a significant increase in inflammatory cytokines (GCSF, IP10, MCP1, MIP1A, and TNFα, among others) in sicker patients admitted to intensive care. In the absence of effective treatments for the management of patients with COVID-19 and respiratory failure, the immunomodulatory and anti-inflammatory effect of colchicine on cytokines involved in the hyper-inflammatory state is postulated. Several lines of research worldwide are testing powerful anti-inflammatory drugs for the pandemic, with different options including steroids, cytokine blockers, and other potent anti-inflammatory agents. Steroids are partially contraindicated in viral infections.
Colchicine is a powerful anti-inflammatory drug approved for the treatment or prevention of gout and Familial Mediterranean Fever at doses ranging between 0.3 mg and 2.4 mg/day. Its mechanism of action is through the inhibition of tubulin polymerization, as well as through potential effects on cellular adhesion molecules and inflammatory chemokines. It might also have direct anti-inflammatory effects by inhibiting key inflammatory signalling networks known as inflammasome and pro-inflammatory cytokines. Additionally, evidence suggests that colchicine exerts a direct anti-inflammatory effect by inhibiting the synthesis of tumor necrosis factor alpha and IL-6, monocyte migration, and the secretion of matrix metalloproteinase-9. Through the disruption of the cytoskeleton, colchicine is believed to suppress secretion of cytokines and chemokines as well as in vitro platelet aggregation. All these are potentially beneficial effects that might diminish or ameliorate the COVID-19 inflammatory storm associated with severe forms of the disease. Importantly, in one contemporary trial low-dose colchicine administered to patients who survived from acute coronary syndrome shows a statistically significantly reduction of cardiovascular complications.
We have therefore designed in a simple, pragmatic randomized controlled trial to test the effects of colchicine on severe hospitalized COVID-19 cases with the aim of reducing mortality.
Sample size calculation:
A minimum sample size of 1200 patients will provide 80% power to detect a relative risk reduction of approximately 30% in the treated group if the assumed composite rate (new requirement of intubation and / or death) in the control group is about 24%.
The ECLA PHRI COLCOVID Trial allows randomization to another trial, specifically patients included in the trial might be (or not) randomized to an antithrombotic strategy.
