Hidroxicloroquina With Azitromicina Versus Hidroxicloroquina and Placebo Int Patients With Mild COVID-19

Overview

Chloroquine and hydroxychloroquine are two antimalarial drugs that are also used in autoimmune diseases. Chloroquine analogs have been shown to inhibit endosome acidification and exhibit nonspecific antiviral activity at high micromolar concentration in vitro against a wide range of emerging viruses (HIV, dengue, hepatitis C, chikungunya, influenza, Ebola, SARS, and MERS ). virus) and more recently COVID-19. On the other hand, azithromycin is a macrolide antibiotic indicated for infections caused by sensitive pathogens, but which in combination with Hydroxychloroquine has shown a synergistic effect against the SARS-CoV-2 virus. International studies show the lack of beneficial effect in hospitalized or mechanically ventilated patients. Referring that because these medications reduce the in case of having a beneficial effect it would be in the early onset, to avoid inflammation (cytokine storm), and thus prevent hospitalizations. The present study focuses on characterizing the possible synergy of the fixed combination of hydroxychloroquine associated with azithromycin in the treatment of Covid-19 from mild to moderate manifestations. Three treatment schemes are proposed with a 10-day follow-up, a) the fixed combination of Hydroxychloroquine / Azithromycin (combination of interest), b) Hydroxychloroquine (active comparison group) and c) non-active control group, using placebo. A group of patients between 18 and 75 years old is considered, who may or may not present other comorbidities. Follow-up will be carried out through quantification of viral load, evaluation of the systemic inflammatory state, changes in clinical manifestations and possible effect on the reduction of hospitalizations. Therefore, it is proposed to carry out the following project. objective To determine the efficacy and safety of Hydroxychloroquine / Azithromycin fixed combination compared to Hydroxychloroquine or placebo in outpatients with Research design: Phase II, multicenter, prospective, randomized, parallel, longitudinal, double-blind study. Medications to use Group 1. Fixed combination of Hydroxychloroquine with Azithromycin 200 mg / 250 mg one tablet every 12 hours for five days and continue with Hydroxychloroquine 200 mg one tablet every 12 hours for 5 more days. Group 2. Hydroxychloroquine 200 mg, one tablet every 12 hours for ten days. Group 3. Placebo one tablet every 12 hours for ten days.
