impact of colchicine in hospitalized colombian patients with covid-19

Conditions: Corona Virus Infection

Summary: this is a phase iiia, prospective, open-label, randomized, parallel-group study designed to evaluate the efficacy and safety of oral colchicine plus standard therapy versus standard therapy in the clinical course of sars-cov-2 infection, in a population group with moderate covid-19 compromise and requiring hospitalization.aproximately 120 subjects meeting all inclusion and not inclusion criteria will be randomized to receive either colchicine plus standard treatment or only standard treatment for 15 days

introduction: covid-19 and mortality associated with acute respiratory distress syndrome (ards) pose a global public health problem. the increase in spread and associated mortality poses a scenario where cost-effective therapeutic options are urgently and effectively proposed to control and reduce the pandemic and even to reduce the number of deaths objective: to evaluate the efficacy and safety of oral colchicine plus treatment standard versus standard treatment in the clinical course of sars-cov-2 virus infection, in a population group with moderate covid-19 involvement and requiring hospitalization. methodology: a prospective, open, randomized, parallel-group study, the sample size of 120 subjects each arm of 60 subjects. random assignment (1: 1) to either colchicine plus standard treatment or control arm (standard treatment) orally for 14 days. an initial dose of 1.5 mg orally on the first day, followed by 0.5 mg every 12 hours on days 2 to 7 and continuing with 0.5 mg a day until completing 14 days ± 1. it will be followed on days 1, 3, 7, 14, and day 28, evaluating physical examination, clinical situation, laboratories, and adverse events. the primary efficacy data correspond to the deterioration in the clinical status of the patients through the semiquantitative ordinal scale suggested by the who r\&d committee. expected results: it is expected to find out how, through different pathways, colchicine could act in modulating or preventing the appearance of ards associated with covid-19, its possible effects on viral replication and antigenic presentation.
