Objectives: We will evaluate the efficacy and safety of favipiravir and interferon beta-1a compared to lopinavir/ritonavir and interferon beta-1a in patients with confirmed COVID-19, who are moderately ill.Trial Design: This is a phase 3, single-center, randomized, open-label, controlled trial with a parallel-group design carried out at Shahid Mohammadi Hospital, Bandar Abbas, Iran.Participants: All patients with age ≥ 20 years admitted at the Severe Acute Respiratory Syndrome Departments of the Shahid Mohammadi Hospital, Bandar Abbas, Iran, will be screened for the following criteria.Inclusion Criteria: 1. Confirmed diagnosis of infection with SARS-CoV-2 using polymerase chain reaction and/or antibody tests. 2. Moderate COVID-19 pneumonia (via computed tomography and/or X-ray imaging), requiring hospitalization. 3. Hospitalized ≤ 48 h. 4. Signing informed consent and willingness of the participant to accept randomization to any assigned treatment arm.Exclusion Criteria: 1. Underlying conditions, including chronic hepatitis, cirrhosis, cholestatic liver diseases, cholecystitis, peptic ulcers, acute and chronic renal failure, and peptic ulcers. 2. 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 O2 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. Recruitment began on 25 July 2020 and is anticipated to be completed by 25 September 2020.Trial Registration: Iranian Registry of Clinical Trials (IRCT) IRCT20200506047323N3 . Registered on 22 July 2020.Full Protocol: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1).

Objectives: To investigates the effectiveness of curcumin-containing Nanomicelles as a therapeutic supplement in the treatment of patients with COVID-19 and its effect on immune responses balance changes following treatment.Trial Design: This study is conducted as a prospective, placebo-controlled with parallel group, single-center randomized clinical trial on COVID-19 patients.Participants: Patients are selected from the COVID-19 ward of Shahid Mohammadi Hospital in Bandar Abbas, Iran.Inclusion Criteria: 1. Real time PCR-approved positive COVID-19 test. 2. Both gender 3. Age between 18 and 75 years 4. Signing a written consent 5. Lack of participation in other clinical trials Exclusion criteria: 1. Pregnancy or lactation 2. Allergy to turmeric or curcumin 3. Smoking 4. Patient connected to the ventilator 5. SaO2 less than 90% or PaO2 less than 8 kPa 6. Having comorbidities (such as severe renal failure, Glomerular filtration rate less than 30 ml/min, liver failure, Congestive heart failure, or Chronic obstructive pulmonary disease) 7. History of gallstones 8. History of gastritis or active gastrointestinal ulcer INTERVENTION AND COMPARATOR: In addition to the routine standard treatments for COVID-19, in the intervention group, 40mg nanomicelles containing curcumin (SinaCurcumin Capsule, Exir Nano Sina Company, Iran), four times per day (after breakfast, lunch, dinner and before bedtime) and in the placebo group as the control group, capsules with the same appearance and characteristics (Placebo capsules, Exir Nano Sina Company, Iran) are prescribed for two weeks.Main Outcomes: The effectiveness of Nano micelles containing curcumin treatment will be evaluated as daily clinical examinations of patients in both groups and, on days 0, 7 and 14, complete clinical symptoms and laboratory findings including peripheral blood and serum parameters such as inflammatory markers will be measured and recorded. Moreover, in order to evaluate the balance of immune responses changes following treatments, serum level of IFN-γ, IL-17, Il-4 and TGF-β serum cytokines will be measured in both groups at time points of 0, 7 and 14 days post treatment. Gene expression of t-bet, GATA-3, FoxP3 and ROR- γT will also be measured at mentioned time points to assess the shift of T helper1, T helper2, T regulatory and T helper 17 immune responses following treatment.Randomisation: Randomized trials will be performed on 40 COVID-19 patients which will be randomized using encoded sealed boxes with computer generated random digits with 1:1 allocation ratio. In order to randomization, placebo and SinaCurcumin Capsules will be numbered first by computer generated random digits. SinaCurcumin and placebo will then be stored and numbered in sealed packages based on generated random numbers. Finally, according to the order in which patients enter the study, packages are given to patients based on their number.Blinding (masking): The present study will be blind for all patients, physicians and nurses, laboratory technicians and statisticians.Numbers To Be Randomised (sample Size): A total of 40 patients will be included in the study, 20 of them will be randomly assigned to the intervention group and 20 to the placebo group.Trial Status: This is Version 1.0 of protocol dated 21 May 2020. The recruitment was started June 24, 2020 and is expected to be completed by October 31, 2020.Trial Registration: This present clinical trial has been registered in the Iranian Registry of Clinical Trials (IRCT) with the registration code of "IRCT20200611047735N1", https://www.irct.ir/trial/48843 .
