Vitamin D3: 5,000iu oral capsule daily for 14 days

Trial Arm 1 Plus
Inpatients: IV Vitamin C (Sodium Ascorbate)
50mg/kg every 6hrs on day 1 followed by 100mg/kg every 6hrs (4x day, 400mg/kg/day) for 7 days (average 28g.day; maximum dose of 50g/24hrs for those weighing more than 125kg).

Sample size calculation
The MINIMUM sample size required is N=100 in each intervention arm in order to have 80% statistical power to detect a 30% relative risk reduction (RRR) in the proportion progressing to mechanical ventilation or death, assuming a standard-of-care risk of progression of 30%. Since participants will be hospitalized, we assumed minimal (<1%) loss to follow-up.

Outpatient recruitment is ongoing, therefore the target sample size has been increased to n=500 (including n=300 outpatients and n=200 inpatients).

Statistical analysis methods
The primary analysis of efficacy will be conducted under the intention-to-treat principle; all randomized participants will be included in the analyses. All results will be analyzed with 2-sided level of significance of 0.05. Given the rapid assessment of the primary outcomes of progression, and the expected absence of loss to follow-up, we will compare the proportions of progression events between the two study arms for each of the factorial randomizations rather than the times to progressions. The primary analysis will use the Z-test for comparison of proportions. Secondary analyses will include adjusting the intervention effect for demographics, exposure characteristics, and severity of disease upon admission, using logistic regression models.

Summary
Brief summary
COVID-19 is a global pandemic.
So far encouraging results have been shown in different parts of the world with the utilisation of hydroxycloroquine, zinc, and azithromycin, and early studies into some of these, plus some with IV Vitamin C, have also proven beneficial. Vitamin D levels have also been shown to be an important indicator to the severity of symptoms in COVID-19 patients. Anticoagulation has also proven to be highly beneficial in patients hospitalized with COVID-19. This study aims to find the optimal treatment protocol for hospitals to consider in their treatment of COVID-19 patients and their endeavours to save lives.

Stage 1 of the outpatient group in Australia is ongoing.

Stage 1 of the inpatient/ hospitalised patient group in Turkey has now been published.
