Plain English Summary

Background and study aims
The COVID-19 pandemic which began in late 2019 has raged across the globe with more than 4 million infections and 300,000 deaths recorded to date. A broad theme of immune overreaction has emerged as a key determinant of disease severity and patient outcome. Intuitively, immunomodulation becomes an attractive potential treatment strategy. Besides lung involvement, COVID-19 is a multi-organ phenomenon and appropriate systemic inflammatory control is necessary for overall survival benefit. Much of the current treatment effort is targeted at viral elimination instead of modulating immune overreaction. A number of immunomodulatory agents may be helpful including vitamin D, magnesium and vitamin B12. Importantly, these compounds are generally safe and well-tolerated by patients. A short course of these three supplements (DMB) could potentially exert synergistic effects to improve COVID-19 severity. This study aims to determine the usefulness of combination of vitamin D, magnesium and vitamin B12 in older COVID-19 patients.

Who can participate?
COVID-19-positive patients aged 50 and over

What does the study involve?
Patients will be given a combination of vitamin D, magnesium and vitamin B12, up to 14 days. The risk of clinical deterioration (requirement for supplemental oxygen and/or intensive care support) is measured using patient records from the hospital information system at day 30.

What are the possible benefits and risks of participating?
If proven to be effective, DMB could reduce the severity of COVID-19 in older patients. There is minimal risk since these supplements are generally safe and well-tolerated by patients.

Where is the study run from?
Singapore General Hospital (Singapore)

When is the study starting and how long is it expected to run for?
March 2020 to May 2020
