Use of Hydroxychloroquine Alone or Associated for Inpatients With SARS-CoV2 Virus (COVID-19)

WithdrawnPhase 3

Sponsor: Apsen Farmaceutica S.A.

Conditions: Coronavirus Infections, SARS-CoV 2, SARS (Severe Acute Respiratory Syndrome), Pulmonary Disease

Interventions: Hydroxychloroquine Sulfate, Hydroxychloroquine Sulfate + Azythromycin

Countries: Brazil

The Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV2) has been identified in Wuhan, China, which causes severe pulmonary complications and flu syndrome, which has spread rapidly to all continents. Approximately 25% of hospitalized patients require treatment in intensive care units and 10% require mechanical ventilation. The diagnosis is made by the molecular polymerase chain reaction test. However, diagnostic tests are limited. The clinical care of the patient with COVID-19 is similar to that of patients with severe infectious respiratory complications, consisting of support and oxygen supplementation. Several medications have been tested as remdesivir, a pro-drug nucleoside, which acts by inhibiting viral RNA transcription, although a recently published study has shown no benefit. China recently approved the use of favipiravir, an antiviral used for influenza, as an experimental therapy for COVID-19. Hydroxychloroquine is a drug with great potential treatment, as it can inhibit the pH-dependent steps of replication of various viruses, with a potent effect on SARS-CoV infection and spread. In this way, the present study will evaluate the safety and efficacy of the hydroxychloroquine in patients with symptomatic SARS-Cov2.
