Brief Summary:
Due to the rapidly developing nature and severity of the COVID-19 pandemic, clinical trials involving a repurposed drug approach are the best option for rapidly identifying an effective COVID-19 therapeutic. The investigators propose to evaluate the efficacy of Montelukast in attenuating cytokine storm syndrome and ARDS via a randomized, blinded, placebo-controlled clinical trial. Specifically, our primary objective is comparing the efficacy of low-dose Montelukast versus placebo in reducing the risk of acute care visits and hospital admissions among COVID-19 positive patients in the general population.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Montelukast 10mg Phase 3

Detailed Description:

Background:Due to the immense humanitarian and economic toll of the COVID-19 pandemic, effective therapies are urgently required to reduce the severity, and mortality, of SARS-CoV-2 infections. A repurposed drug approach is the best option to rapidly identify a therapeutic that is effective at reducing the impact of SARS-CoV-2 and improving the clinical outcomes of severe COVID-19 patients. Two of the main complications observed in severe patients are the development of acute respiratory distress syndrome (ARDS) and a hyperinflammatory cytokine profile that is often termed a cytokine storm. NF-B (nuclear factor kappa-light-chain-enhancer of activated B cells) is a protein complex involved in cytokine production, among other biological processes, including control of many genes involved in innate and adaptive immune responses, and inflammation. NF-B is known to be a key player in inflammatory responses and is a rapid-acting 'first responder' to harmful stimuli, such as viral infections. Inhibition of the NF-B signaling pathway has been explored for its therapeutic potential in inflammatory diseases, with attenuation of NF-B activation often associated with a reduction in cytokine production. Montelukast, an FDA and Health Canada approved asthma drug, has been shown to inhibit the signalling of NF-B, such as interleukin-6,8,10, TNF-alpha, MCP-1, and other proinflammatory mediators. Montelukast is available as a low-cost generic and has an excellent safety profile. The investigators hypothesize that repurposing Montelukast to target suppression of NF-B activation in COVID-19 positive patients will result in a corresponding reduction of proinflammatory mediators, thereby attenuating cytokine production, and taming the cytokine storm. Additionally, the investigators are proposing that a reduction in proinflammatory mediators by Montelukast will result in a mitigation of severe COVID-19 symptoms, and serve as a therapeutic for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, thereby alleviating severe complications/symptoms of the viral infection, such as ARDS and cytokine storm syndrome.

Research Aims:The overall objective of this proposal is to determine the efficacy of Montelukast in reducing the severity of COVID-19 symptoms using a large blinded randomized controlled trial. Our primary objective is comparing the efficacy of low-dose Montelukast versus placebo in reducing the risk of acute care visits and hospital admissions among COVID-19 positive patients in the general population. Our secondary objectives are to compare the efficacy of Montelukast versus placebo in reducing: a) All cause mortality, b) Inpatient length of stay, c) Time to intensive care unit, d) Time to intubation, e) Time to complications (pneumonia, acute respiratory distress syndrome (ARDS), cardiomyopathy/arrhythmia, acute kidney injury, secondary bacterial infections), f) Symptom severity (via weekly phone, and/or online, assessments), and g) ER and hospitalization visit counts. A tertiary objective of the proposal is the development of a new COVID-19 specific symptom severity index.

Methods and Approaches: The COvid-19 Symptom Montelukast (COSMO) Trial will be a parallel assignment, phase III, quadruple blinded (i.e. participant, care provider, investigator, outcomes assessor), randomized, placebo-controlled trial of Montelukast for the treatment of SARS-CoV-2 infections. Participants will be randomized using a 1:1 allocation ratio to receive either treatment (10mg oral Montelukast) or matched placebo once daily, for 60 consecutive days following positive COVID-19 test. The study will included 600 adults aged 40+, and balanced by sex and age groups. The RCT is multi-site and will be conducted at the Integrated Health and Social Services University Network for West-Central Montreal and the Jewish General Hospital, with the utilization of the Segal Cancer Centres clinical trials infrastructure.
