Details and patient eligibility

About

This is a phase 3 clinical trial, randomized, single-center, opened, controlled, to evaluate efficacy and safety of early administration of colchicines in patients older than 60 years, with high risk of pulmonary complications due to coronavirus SARS-CoV2 (COVID-19). An approximately number of 954 subjects meeting all inclusion and none exclusion criteria will be randomized either to receive colchicines or symptomatic treatment with paracetamol during 21 days.

Full description

The primary objective of the study is to determine whether short term course of colchicines reduces number of deaths due to COVID-19 and severe complications due to the virus in elderly patients with comorbidities.

The secondary objective is to determine the safety of colchicines in this patient population.

Approximately 954 subjects who meet all inclusion criteria and none exclusion criteria will be randomized either to receive colchicines or symptomatic treatment (2:1 allocation ratio) during 21 days. Follow-up assessments will occur every 48 hours and always at day 10, 21 and 61 following randomization for evaluation of the occurrence of any trial endpoints or other adverse events.
