Brief Summary:
This is an open-label, multicenter, parallel-group, randomized, phase III trial that evaluates the efficacy and safety of hydroxychloroquine and favipiravir in the treatment of patients with possible or confirmed COVID-19 observed within the last 5 days. 1000 patients will be randomized in 2:1:2:2:2:1 ratio and divided into six groups.

Condition or disease Intervention/treatment Phase
Sars-CoV2 COVID-19 Drug: Favipiravir (3200 mg + 1200 mg) Drug: Favipiravir (3600 mg + 1600 mg) Drug: Favipiravir (3200 mg + 1200 mg) combined with Hydroxychloroquine Drug: Favipiravir (3200 mg + 1200 mg) combined with Azithromycin Drug: Hydroxychloroquine Drug: Hydroxychloroquine combined with Azithromycin Phase 3

Detailed Description:

The clinical picture of 2019-nCoV disease is in a broad spectrum, which includes asymptomatic infection, a mild upper respiratory tract infection, respiratory failure, and even severe viral pneumonia with death. Although the mortality rate is not yet clear, the reported case-fatality risk was 11-14% during the initial studies which included patients with severe disease. The overall case fatality rate was reported as approximately 2%. In addition, most cases have resulted in a pneumonia requiring supplemental oxygen therapy and ventilator support. The alarming levels of spread and severity of COVID-19 caused a global emergency and this outbreak has been characterized as a pandemic by the World Health Organization (WHO).

The investigational product Favipiravir is an antiviral drug against RNA viruses and has been stated as effective for the treatment of COVID-19, first emerged from China, in various clinical studies. In February 2020, Favipiravir was used for the clinical treatment of COVID-19, has been shown to be more effective than the lopinavir / ritonavir combination in 80 people. In recent researches, the drug favipiravir is suggested that it may induce recovery in a short time in patients with COVID-19-mild type and decrease the treatment duration from 11 days to 4 days.

The investigational product hydroxychloroquine sulfate is a 4- aminoquinoline derivative and widely used for the treatment of many rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus in addition to its antimalarial effects. In vitro studies reported that hydroxychloroquine sulfate may be effective against many viruses, including SARS-CoV-2 in many in vitro experiments. Additionally, preliminary results of limited number of studies have been revealed that hydroxychloroquine sulfate reduces virus load and induces improvement in patients with COVID-19. This agent has been also suggested to be used in COVID-19 prophylaxis.

Until now, there is no official report on whether hydroxychloroquine combined with favipiravir show clinical activity against the new coronavirus, COVID-19, in Turkey. The main purpose of this study is to evaluate the efficacy and safety of hydroxychloroquine and favipiravir in the treatment of Turkey population with COVID-19.

This study designed as an open-label, multicenter, parallel-group, randomized, phase III clinical drug trial.

A total of 1000 subjects aged between 18 to 70 years with symptoms and complaints consistent with possible or confirmed COVID-19 observed within the last 5 days and meet all eligibility criteria will participate in the study.

This study will be conducted in 14 sites.
