This is an open-label, non-randomized clinical trial study. The number of 40 COVID-19 patients with moderate severity will be admitted in progressive care units (PCUs) and intensive care units (ICUs) enrolled in the study. The sampling will be purposive and based on the same independent variables, including age, gender, past medical histories, and the situation of the patient at the admission day, and ventilator support. The patients will be allocated into two groups with different regimens. Group "A" (regimen A)will be defined as Favipiravir 1600 mg a first dose and 600 mg in 3 divided doses daily plus 400 mg in 2 divided doses of Hydroxychloroquine every day. The group "B" (regimen B) will be contained 400 mg of Lopinavir/Ritonavirin 2 divided doses plus the first dose (400 mg) of Hydroxychloroquine. Hydroxychloroquine will not be used for adverse drug reactions. The regimen remained at least 7 up to 10 days. Data will be analyzed using statistical package for social sciences (SPSS) version 18 (SPSS Inc. Chicago, IL, USA) for windows. The variables will be compared using independent and paired T-test for normally distributed variables and Wilcoxon, Chi-square for non-normal distributed variables. The Kaplan Meier test will be used for survival analysis and the one-sample Kolmogorov-Smirnov test for the evaluation of distributions.

Hydroxychloroquine is widely used to treat autoimmune diseases. Clinical investigation has found that a high concentration of cytokines were detected in the plasma of critically ill patients infected with SARS-CoV-2, therefore, hydroxychloroquine as anti-inflammatory agents may reduce this response in accord with their use in autoimmune disease where the cytokine response can be reduced. Favipiravir is an antiviral drug developed in Japan that the data sheet notes that it is a pyrazinecarboxamide derivative with activity against influenza viruses, west nile virus, yellow fever virus, foot and mouth disease virus as well as against flaviviruses, arenaviruses, bunyaviruses and alphaviruses. In February the drug was used for COVID-19 disease in China and was declared effective in treatment, and a report published (in press) comparing Favipiravir with Lopinavir /ritonavir suggested that Favipiravir was superior for prevention of disease progression and viral clearance. The objective of this pilot study is to compare three arms: hydroxychloroquine; favipiravir; standard care (no specific SARS-CoV-2 treatment) only, in symptomatic patients infected by SARS-CoV-2 in an open label randomized clinical trial. The difference between groups will allow an effect size to be determined for a definitive clinical trial.

A recent outbreak of coronavirus disease 2019 (COVID-19) caused by the novel coronavirus designated as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) started in Wuhan, China, at the end of 2019. The clinical characteristics of COVID-19 include respiratory symptoms, fever, cough, dyspnea, and pneumonia. As of 25 February 2020, at least 77 785 cases and 2666 deaths had been identified across China and in other countries; in particular, 977 and 861 cases were identified in South Korea and Japan, respectively. The outbreak has already caused global alarm. On 30 January 2020, the World Health Organization (WHO) declared that the outbreak of SARS-CoV-2 constituted a Public Health Emergency of International Concern (PHEIC), and issued advice in the form of temporary recommendations under the International Health Regulations (IHR).It has been revealed that SARS-CoV-2 has a genome sequence that is 75%-80% identical to that of SARS-CoV, and has more similarities to several bat coronaviruses. SARS-CoV-2 is the seventh reported human-infecting member of the family Coronaviridae, which also includes SARS-CoV and the Middle East respiratory syndrome (MERS)-CoV. It has been identified as the causative agent of COVID-19. Both the clinical and the epidemiological features of COVID-19 patients demonstrate that SARS-CoV-2 infection can lead to intensive care unit (ICU) admission and high mortality. About 16%-21% of people with the virus in China have become severely ill, with a 2%-3% mortality rate. However, there is no specific treatment against the new virus. Therefore, it is urgently necessary to identify effective antiviral agents to combat the disease and explore the clinical effect of antiviral drugs. One efficient approach to discover effective drugs is to test whether the existing antiviral drugs are effective in treating other related viral infections. Several drugs, such as ribavirin, interferon (IFN), Favipiravir (FPV), and Lopinavir (LPV)/ritonavir (RTV), have been used in patients with SARS or MERS, although the efficacy of some drugs remains controversial. It has recently been demonstrated that, as a prodrug, Favipiravir (half maximal effective concentration (EC50) = 61.88 μmol·L−1, half-maximal cytotoxic concentration (CC50) > 400 μmol·L−1, selectivity index (SI) > 6.46) effectively inhibits the SARS-CoV-2 infection in Vero E6 cells (ATCC-1586). Furthermore, other reports show that FPV is effective in protecting mice against Ebola virus challenge, although its EC50 value in Vero E6 cells was as high as 67 μmol·L−1. Therefore, clinical studies are urgently needed to evaluate the efficacy and safety of this antiviral nucleoside for COVID-19 treatment. After enrollment of the patients (day 1) depending on inclusion and exclusion criteria and laboratory findings confirming the presence of the COVID-19 virus, 25 patients will receive Favipiravir plus standard treatment and the second group of 25 patients will receive standard treatment only. The comparison of the findings of the follow up studies on days 4, 7, and 10 in terms of clinical manifestations, chest X-ray and laboratory findings, such as Real Time Polymerase Chain Reaction (RT-PCR) results for viral presence will determine whether Favipiravir has safety and efficacy against COVID-19 infections. All ethical issues related to this trial including right of the participants to withdraw from the study should be maintained according to of guidelines of International Conference on Harmonisation (ICH)-Good Clinical Practice (GCP).

The study is Phase II/III and consists of pilot and pivotal stages. The objective of the pilot stage is to conduct a preliminary assessment of the efficacy and safety of Favipiravir, and to select the optimal dosing regimen to study during the pivotal stage. The objective of the pivotal stage is to assess the efficacy and safety of Favipiravir compared with the Standard of care (SOC) in hospitalized patients with moderate to severe COVID-19 pneumonia.

This is a randomised placebo controlled phase II trial to examine the efficacy of antivirals to treat COVID-19 infection compared to placebo for virological cure and improved clinical outcomes. Individuals will be randomised to the candidate antiviral which in the first instance is Favipiravir or matched placebo and randomisation will be stratified according to whether the participant requires hospitalisation or not. This treatment will be given in addition to the usual standard of care in the participating hospital.

To address the need to intervene to prevent the spread of COVID-19 in long-term care homes, we propose a randomized clinical trial of chemoprophylaxis in long-term care homes experiencing COVID-19 outbreaks. LTCH units experiencing an outbreak of COVID-19 will be randomized to chemoprophylaxis with favipiravir or placebo in a 1:1 ratio. Chemoprophylaxis in this setting refers to the use of favipiravir for pre-exposure prophylaxis, post-exposure prophylaxis, pre-emptive therapy, or treatment for established COVID-19. This design mimics the approach to influenza outbreaks, which has proven efficacy for outbreak control. The primary outcome will be control of the outbreak, defined as no new microbiologically confirmed case of COVID-19 for 24 consecutive days up to day 40.

Favipiravir is a selective and potent inhibitor of influenza viral RNA polymerase. It acts as a purine analogue, which selectively inhibits viral RNA-dependent RNA polymerase (RdRps). It has the characteristic of acting on RNA viruses including Ebola and Coronaviruses especially novel coronavirus (2019-nCoV). The purpose of this study is to evaluate the clinical efficacy and safety of Favipiravir in comparison to placebo in the treatment of mild COVID-19 cases. It is a Multicenter, randomized double-blinded, parallel-group trial.
