Brief summary

The most prevalent complication of COVID-19 infection is respiratory failure from severe acute respiratory syndrome (SARS), the leading cause of mortality. There is increasing indication that the decompensation in severe COVD-19 infection may be due to a cytokine storm syndrome. This hyperinflammatory syndrome results in a fulminant and fatal hypercytokinemia and multiorgan failure. Approximately 15% of patients with COVID-19 infection are hospitalized and 20-30% of these hospitalized patients require ICU care and/or mechanical ventilation. Overall mortality in hospitalized patients is approximately 20-25%. There is significant interest in therapies that can be given upstream to reduce the rate of mechanical ventilation and thus mortality. We hypothesize that treatment with colchicine in COVID-19 moderate-severe patients may decrease the risk of progression into ARDS requiring increased oxygen requirements, mechanical ventilation, and mortality.

Detailed description

Prospective, completely randomized, open labeled, controlled study. Patients will be randomized into two groups (A and B). Patients of group A will be treated under what is considered current standard of care at Maimonides Medical Center while group B patients will receive colchicine in addition to standard of care. Treatment arm In addition to the local standard of care for COVID 19 patients, the patient will receive colchicine PO as such: * Loading dose of 1.2 mg followed by 0.6mg after 2 hours if without significant gastrointestinal symptoms (day 1) * The next day 0.6mg bid for 14 days or until discharge Patients who are on HMG-Co A Reductase Inhibitors (atorvastatin, fluvastatin, pravastatin, simvastatin), fibrates, genfibrozil, amiodarone, dronedarone or digoxin should have the colchicine dosage reduced to a loading dose of 0.6mg followed by 0.3mg after two hours (day 1) followed by 0.3mg BID for 14 days or until discharge. If patients have significant gastrointestinal symptoms after loading, the dosage may be reduced to 0.3mg BID for the rest of the 14 day course or until discharge. If gastrointestinal symptoms continue, the medication should then be discontinued. Patients who experience sensory motor neuropathy, or symptoms and laboratory findings consistent with rhabdomyolysis should prompt immediate discontinuation of the drug. If renal function deteriorates during the treatment course and CrCl \<30ml/min, colchicine should also be discontinued. Control arm Usual medical therapy (can include medications such as hydroxychloroquine, azithromycin) Patients should NOT receive, Remdesivir, IL-6 inhibitors (Tociluzimab, Sarilumab), JAK inhibitors, IL-1 inhibitors, or other immunomodulators for COVID-19 before randomization. Since the primary clinical endpoint is progression of disease, if the patient requires beyond 8L nasal cannula, eg. high flow O2 or mechanical ventilation, the primary clinical endpoint is met and the above experimental medications will be permitted. To rephrase, the patient will be allowed, Remdesivir, IL-6 inhibitors and other immunomodulators if then deemed medically necessary by the treating physician.

Interventions

DRUGColchicine

People in the colchine group will be given a starting dose of 1.2 mg followed, by 0.6mg after 2 hours if they do not have significant gastrointestinal symptoms, on day 1. After that, they will take colchicine 0.6mg twice a day for 14 days or until discharged or release from the hospital.

DRUGUsual Care

COVID Patients in this arm will receive usual care COVID19 treatment and will not receive colchine.

Dyspnea 2. Respiratory frequency ≥ 30/min 3. Blood oxygen saturation ≤ 93% * AND one or more of the following: (positive PCR test or positive antibodies) or (CT/Chest X-ray consistent with COVID19 infection) or (anosmia).

Exclusion criteria
