Clinical Trial Summary

The recent inception of the coronavirus SARS-CoV-2, responsible for the coronavirus disease (COVID-19), has caused thousands of deaths globally. The most frequently reported complications among COVID-19 patients are from respiratory involvement.

Vitamin D has immunomodulatory effects that could protect against COVID-19 infection. Indeed, there is good evidence from randomized clinical trials suggesting that high doses of vitamin D administered during cold seasons prevent viral respiratory infections in at risk individual, and more recently, observational studies suggested that the mortality rate from COVID-19 is inversely correlated with levels of serum 25(OH)vitamin D.

The hypothesis of the study is that a high dose of vitamin D given orally to patients admitted to the hospital for COVID-19 will prevent the occurrence of respiratory deragement and other adverse clinical events.

To evaluate the aforementioned hypothesis, a randomized, controlled, double-blind, clinical trial comparing a 500.000 UI dose of vitamin D versus placebo among COVID-19 patients at moderate risk, requiring hospitalization but without requirements of critical care at admission was designed. The intervention will be one dose of 500.000 UI given orally or matching placebo.

The trial has a sequential design with two steps:

• The first step, projected to include 200 patients, will assess the effects of the intervention on the respiratory SOFA; and

• If there is a detectable effects, the second step, projected to include 1264 patients, will assess the effects on a combined event that includes need of high dose of oxygen or mechanical ventilation.

All study outcomes will be measured during the index hospitalization.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Respiratory SOFA.	Is the respiratory component of the sequential organ failure assessment score (SOFA score). It is a 4 points scale, each point indicate a deeper respiratory impairment. The score is based on the relationship between the arterial pressure of oxygen (PaO2) and inspired fraction of oxygen (FiO2), as the ratio of both (PaFi). In the cases were arterial blood gas are not measured, the pulse oximetry will be used instead.; The respiratory SOFA is as follows: 1: PaO2/FiO2 >=300; 2: PaO2/FiO2 >=200 and <300; 3: PaO2/FiO2 >=100 and <200; 4: PaO2/FiO2 <100.; The minimum respiratory SOFA score will be record on daily basis during first week or to death or discharge, whichever occur first.; This outcome is the primary outcome of the first study phase.	One week
Primary	Need of a high dose of oxygen or mechanical ventilation.	The start of oxygen supplementation at FiO2 >40% or the initiation of invasive through orotracheal intubation) or non-invasive ventilation (Continuous positive airway pressure or Bilevel positive airway ventilation).; This outcome will be recorded during hospitalization to 30 days, the death or discharge, whichever occur first.; This is the primary outcome of the second study phase.	30 days
Secondary	Change in oxygen saturation.	Difference between the oxygen saturation at study entry and the lowest oxygen saturation measured during the first week, the death or discharge, whichever occur first.; The oxygen saturation will be measured by pulse oximetry using commercially available devices.	One week
Secondary	Oxygen desaturation.	Oxygen saturation equal or less than 90% in any moment during the hospitalization. This outcome will be measured by pulse oximetry using commercially available devices.; The outcome will be measured during the first week, the death or hospital discharge, whichever occur first.	One week
Secondary	Change in Quick SOFA score.	The difference between the Quick SOFA score at study entry and the highest value recorded during the hospitalization.; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days.
Secondary	Myocardial infarction.	Myocardial infarction is defined as suspicious symptoms with new Q waves in the EKG and enzymatic elevations compatible with the Fourth MI Definition.; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days
Secondary	Stroke.	Stroke is defined as a focal neurological loss lasting >24 hs as reported by treating physician.; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days
Secondary	Acute kidney injury.	Acute kidney injury is defined as an increase of at least 50% in serum creatinine levels (as compared with any previous value during the hospitalization).; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days
Secondary	Pulmonary thromboembolism.	Pulmonary thromboembolism is defined as the presence of suspicious symptoms (i.e. dyspnea) confirmed with objective evidence of a thrombus in the pulmonary tree by CT or MRI or Pulmonary Angiography.; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days
Secondary	Combined endpoint (stroke, myocardial infarction, acute kidney injury and pulmonary thromboembolism.	Combined outcome of the aforementioned events, Stroke is defined as a focal neurological loss lasting >24 hs as reported by treating physician.; Myocardial infarction is defined as suspicious symptoms with new Q waves in the EKG and enzymatic elevations compatible with the Fourth MI Definition.; Pulmonary thromboembolism is defined as the presence of suspicious symptoms (i.e. dyspnea) confirmed with objective evidence of a thrombus in the pulmonary tree by CT or MRI or Pulmonary Angiography.; Acute kidney injury is defined as an increase of at least 50% in serum creatinine levels (as compared with any previous value during the hospitalization).; The outcome will be measured during the hospitalization until 30 days, the death or discharge whichever occur first.	30 days
