OBJECTIVES:To investigate the potential efficacy of Acacia Senegal extract Gum Arabic (GA) supplementation as immunomodulatory and anti-inflammatory dietary intervention among newly diagnosed COVID 19 Sudanese patients. To study the effect of GA on the level of cytokines, TNFα, IL8, IL6 IL10, CRP and the viral load. Secondary outcomes will be the effect of GA oral intake on mortality rate and days of hospital admission. TRIAL DESIGN:Quadruple blind, randomized placebo-controlled clinical trial Phase II & III. Prospective, two-arm, parallel-group, randomised (1:1 allocation ratio) superiority trial of oral GA among seropositive COVID-19 patients. PARTICIPANTS:Inclusion criteria: COVID-19 infected (newly diagnosed) as proved by real-time PCR within 72 hours of PCR. Age 8-90 years Both genders Exclusion criteria: Intubated patients on parenteral treatment Allergy to Gum Arabic The study will be conducted in COVID Isolation Centres and Soba University Hospital Khartoum State Sudan.

MAIN OUTCOMES:Mean change from baseline score of Immune Response to end of the trial. Changes of the level of Tumor Necrosis Factor (TNFα), interleukin IL8, IL6, and IL10 from the baseline values (Four weeks from the start of randomization). Mortality rate: The percentage of deaths among COVID 19 patients received Gum Arabic compared to placebo (Four weeks from the start of randomization]). RANDOMISATION:Randomization (1:1 allocation ratio) and will be conducted using a sequence of computer-generated random numbers by an independent individual. Each participating centre will be assigned a special code generated by the computer. The randomization will be kept by the PI and a research assistant. BLINDING (MASKING):Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) NUMBERS TO BE RANDOMISED (SAMPLE SIZE): 110 eligible patients will be randomly assigned to either GA (n=55) or placebo (n=55) groups. TRIAL STATUS:Protocol Version no 2, 30th June 2020. Recruitment will start on 15th September 2020. The intended completion date is 15th January 2021. TRIAL REGISTRATION:ClinicalTrials.gov Identifier: NCT04381871 . Date of trial registration: 11 May 2020.
