Diagnosed mild pneumonia using computed tomography (CT) and/or chest X-ray (CX-R) imaging, not requiring hospitalization. 2. Signing informed consent. Inclusion criteria for patients with moderate COVID-19 symptoms (inpatients) 1. Confirmed infection using PCR. 2. Diagnosed moderate pneumonia using CT and/or CXR imaging, requiring hospitalization. 3. Hospitalized ≤ 48 hours. 4. Signing informed consent. Exclusion criteria 1. Severe and critical pneumonia due to COVID-19. 2. Underlying diseases, including AIDS, asthma, loiasis, and severe liver and kidney disease. 3.

Control groups: The outpatient group will receive hydroxychloroquine sulfate (Amin Pharmaceutical Company, Iran) at a dose of 400 mg twice a day for the first day and 200 mg twice a day for seven subsequent days. The inpatient group will receive 200/50 mg Lopinavir/Ritonavir (Heterd Company, India) twice a day for the seven days, plus five doses of 44 mcg Interferon beta-1a (CinnaGen, Iran) every other day.

The secondary outcome is the incidence of serious adverse drug reactions within seven days of randomization., Randomization: Patients in both outpatient (mild) and inpatient (moderate) groups will be randomized into the treatment and control groups based on the following method. A simple randomization method and table of random numbers will be used. If the selected number is even, the patient is allocated to the treatment group, and if it is odd, the patient is allocated to the control group in a 1:1 ratio., Blinding (masking): This is an open-label study, and there is not blinding. Numbers to be randomized (sample size) A total number of 120 patients (60 outpatients and 60 patients) will be randomized into two groups (30 patients in each of the intervention groups and 30 patients in each of the control groups)., Trial Status: The protocol is Version 1.0, November 17, 2020. Recruitment began November 25, 2020, and is anticipated to be completed by February 25, 2021., Trial Registration: This clinical trial has been registered in the Iranian Registry of Clinical Trials (IRCT).

Severe and critical COVID-19 pneumonia. 3. History of allergy to favipiravir, lopinavir/ritonavir, and interferon beta-1a. 4. Pregnancy and breastfeeding., Intervention and Comparator: Intervention group: favipiravir (Zhejiang Hisun, China) with interferon beta-1a (CinnaGen, Iran). This group will receive 1600 mg favipiravir twice a day for the first day and 600 mg twice a day for the following 4 days with five doses of 44 mcg interferon beta-1a every other day., Control Group: lopinavir/ritonavir (Heterd Company, India) with interferon beta-1a (CinnaGen, Iran). This group will receive 200/50 mg lopinavir/ritonavir twice a day for 7 days with five doses of 44 mcg interferon beta-1a every other day. Other supportive and routine care will be the same in both groups., Main Outcomes: The primary outcome of the trial is the viral load of SARS-CoV-2 in the nasopharyngeal samples assessed by RT-PCR after 7 days of randomization as well as clinical improvement of fever and O 2 saturation within 7 days of randomization. The secondary outcomes are the length of hospital stay and the incidence of serious adverse drug reactions within 7 days of randomization., Randomization: Eligible patients will be allocated to one of the study arms using block randomization in a 1:1 ratio (each block consists of 10 patients). A web-based system will be used to generate random numbers for the allocation sequence. Each number relates to one of the study arms., Blinding (masking): This is an open-label trial without blinding and placebo control., Numbers to Be Randomized (sample Size): A total of 60 patients will be randomized into two groups (30 patients in the intervention group and 30 patients in the control group)., Trial Status: The trial protocol is version 1.0, 22 July 2020.
