NCT ID: NCT04407507

Last Updated: 2021-05-21

Results Overview

The subject is considered to have progressed to severe illness when one or more of the following criteria are present: 1. Breathing difficulty (≥30 breaths per minute); 2. Resting oxygen saturation ≤93%; 3. Severe complications such as: respiratory failure, need for mechanical ventilation, septic shock, non-respiratory organic failure.

PRIMARY outcome

Timeframe: 14 days

Population: Participants With a Disease Control Status Defined as no Disease Progression to Severe, 3 subjects of the Ivermectin arm group and 7 of the placebo were excluded of the efficacy analysis due to wrong criteria of inclusion (3 of ivermectin and 6 from placebo) and withdrawal of consent (1 in placebo).

The subject is considered to have progressed to severe illness when one or more of the following criteria are present: 1. Breathing difficulty (≥30 breaths per minute); 2. Resting oxygen saturation ≤93%; 3. Severe complications such as: respiratory failure, need for mechanical ventilation, septic shock, non-respiratory organic failure.

SECONDARY outcome

Timeframe: days 1, 5 and 14

Population: Only positive subjects are reported, since Ct is not reported in negative subjects, therefore there is no data available to analyze this criterion, as negative subjects are reported, the values for analysis decrease.

To determine viral load indirectly, the Ct value of the SARS-COV-2 gene N was used on days 1, 5 and 14 of treatment, considering values greater than 37.5 as negative.

SECONDARY outcome

Timeframe: 14 days

Population: Subjects were asked to answer a symptoms dairy during 14 days, where they recorded the presence of the following symptoms; fever, cough, muscular pain, fatigue, breath difficulty, headache, diarrhea, palpitations, expectoration and "Other", in the other question several subjects answer hypogeusia/ageusia, hyposmia/anosmia and backpain.

The total of days anaylized were considered as 100%; 364 days for placebo patients(26 subjects x 14 days), and 420 for ivermectin subjects (30 subjects x 14 days), then the number of days reported correspond to de % of days when symptom was present.
