Official Title
Evaluation de l'efficacité et de la tolérance de Quinquina et d'un phytomédicament " ACAR " en Comparaison Avec l'Hydroxychloroquine Chez Des Adultes Malades de Covid-19 Sans symptômes
Brief Summary

Our previous work on plants has indicated significant antimalarial and antiviral activities. Of these plants, two recipes are proposed for evaluation for COVID-19. It is Cinchona, an antimalarial and a combination of 4 plants with antiviral, antimalarial, antitussive and anti-inflammatory properties. The phase II clinical trial, with three arms and at a rate of 77 patients per arm, received the approval of the National Committee for Ethics and Health Research. This is a non-inferiority test aimed at comparing the therapeutic impact in "add on" to Azithromycin, phytomedicines versus Hydroxychloroquine in asymptomatic COVID-19 patients. After 10 days of treatment, viral clearance and symptom progression will be assessed on days 3, 6 and 14. Clinical, paraclinical and laboratory tests will be performed throughout the 3-month trial. Ethical and deontological considerations will be applied

Detailed Description

All consenting subjects who meet the inclusion criteria will benefit from an individual file which will include data relating to general information, the complete clinical examination and the paraclinical examination. They are distributed randomly into three parallel groups, each arm having a different treatment modality. A balanced randomization by permutation block of 5 will be applied using the "Randomizer for Clinical Trial" application developed by the company Medsharing). Laboratory examinations are carried out according to the procedures and method by laboratories accredited in Guinea for the diagnosis of COVID19. Data is encoded, entered and processed using statistical software.

The comparison between the three cohorts will be made using either the Anova test for continuous variables or the chi-square test for categorical variables. The rate of change over time of virologic clearance, fever and other symptoms values as well as the differences for these rates between treatment arms will be tested using mixed-effects modeling.

The biological samples will be stored at the biobank of the National Institute of Public Health of Guinea.
