Brief summary
The virus SARS-CoV-2 causes severe pneumonia which, in a proportion of patients progresses towards an Acute Respiratory Distress Syndrome (ARDS) mainly related to the antiviral immune response. To date, there is no available treatment that significantly improves outcome of patients with COVID-19 pneumonia. Sphingosine-1-phosphate receptor 1 (S1P1) ligands control vascular leakage in the airways and sphingosine-1-phosphate (S1P) receptor ligands devoid of activity on sphingosine-1-phosphate receptor 3 (S1P3) show an excellent safety profile, including ozanimod. Critically, S1P1 ligands mildly impact, but do not compromise viral clearance and they reduced lung injury in preclinical models, even without concomitant use of antivirals and with a synergistic effect when associated to antiviral agents. Ozanimod was approved by the FDA for the treatment of relapsing multiple sclerosis at the end of March 2020, and was recently (October 2020) approved by Health Canada for the same indication. The investigators believe that this immune modulator is at the top of the list of agents that should be trialed in order to mitigate the morbidity and mortality of COVID-19. The primary objective is to substantiate the impact of ozanimod on key outcomes of COVID-19 patient progression, which will guide decision making around sample size and the choice of endpoints for future clinical trial.
Interventions
DRUGOzanimod
The investigational medical product (IMP) for this study is ozanimod. Ozanimod 0.23 mg be administered once daily for 4 days and then ozanimod 0.46 mg will be administered once daily for ten days.
OTHERStandard of care
During hospitalization, patient will be given standard of care (Recommendations for standard of care management of COVID-19 will be provided for anticoagulation, fluid resuscitation, corticoids and other immunomodulators, antipyretics agents, antiviral agents and other treatments. These recommendations are subject to modifications based on the new literature data).
