Population: 392 Patients with COVID-19 (Coronavirus Disease-19), confirmed by RT-PCR (Real Time polymerase chain reaction), symptomatic in the early phase of the disease.

Experimental group: 196 patients, nitazoxanide 500mg 8 / 8 hours for 5 days. Control group:

196 patients, placebo 8/8 hours for 5 days.

Clinical Trial Description

SARITA-2 is a multicenter, randomized, placebo-controlled, parallel, -blinded, interventional, treatment clinical trial with two arms, which aims to study the impact of nitazoxanide in the early phase of the COVID-19 (Coronavirus Disease-19).

Experimental group: 196 patients received nitazoxanide 500mg 8 / 8 hours for 5 days. Control group: 196 patients received placebo 8/8 hours for 5 days.

Population: 392 Patients with COVID-19, confirmed by RT-PCR (Real Time polymerase chain reaction), symptomatic in the early phase of the disease.

Calculation of the sample size was based on a previous study which demonstrated that 78% of Covid-19 patients in group 4 (Hospitalized without oxygen therapy), according to the WHO ordinal classification, experienced complete resolution of symptoms after receiving placebo.10 In the present trial, patients were classified as group 2 (Symptomatic and independent), and a greater degree of recovery as measured by symptom-free days (80%) was expected even after placebo. Thus, assuming an 11% increase in symptom-free days in those patients who would receive nitazoxanide compared to placebo, we would need approximately 196 patients per experimental group, admitting a beta error of 15% and alpha error of 5%, for a total n of 392 patients. Calculation of the sample size was done by G*Power 3.1.9.2 (Universität Düsseldorf, Düsseldorf, Germany). ;
