PREEMPTIVE THERAPY WITH COLCHICINE IN PATIENTS OLDER THAN 60 YEARS WITH HIGH RISK OF SEVERE PNEUMONIAE DUE TO CORONAVIRUS

PREEMPTIVE THERAPY WITH COLCHICINE IN PATIENTS OLDER THAN 60 YEARS WITH HIGH RISK OF SEVERE PNEUMONIAE DUE TO CORONAVIRUS SARS-CoV2 (COVID-19)

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.

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.

Inclusion Criteria:

1. Patients of both sexes who are at least 60 years old.

2. Diagnosis of COVID-19 infection in the last 72 hours and confirmed by PCR

3. Patient in outpatient follow-up (not hospitalized or under consideration) or institutionalized in senior centers/residences

4. The patient must possess at least two of the following high-risk criteria

   1. 60 years of age or older AND
   2. Any of the following: Diabetes mellitus, high blood pressure, known pulmonary disease (including asthma or chronic obstructive pulmonary disease), known heart failure, known coronary disease, bicytopenia, pancytopenia, or the existence of simultaneous neutrophilia and lymphopenia
