Rayaldee: 30 mcg Extended-Release (ER) Capsule
Placebo
Subjects will be instructed to take a loading dose of 10 capsules (0 mcg) of study drug per day on Days 1, 2 and 3 at bedtime after fasting for at least 3 hours following dinner, with any nonalcoholic liquid, by the oral route.

Timeframe: 42 days

Population: Per protocol population

The FLU- PRO Plus© questionnaire was specifically designed and validated to evaluate in clinical trials the presence, severity and duration of symptoms associated with viral infections. It contains 32 items (eg, felt hot, sweating, headache), grouped into 6 domains, that provide a comprehensive evaluation of such symptoms, using 5-point scales (values ranging from 0 to 4) with higher scores indicating worse symptoms. The number of days to resolution of the selected five COVID-19 symptoms (trouble breathing, chest congestion, dry or hacking cough, body aches and pains, and chills and shivering), defined as a reduction in the aggregate symptom score recorded on Day 0 (prior to study drug initiation) by the FLU-PRO Plus© questionnaire to or below 5 for a minimum of three consecutive days. Flu-PRO Plus© was created and supplied by Dr. John Powers and Leidos Biomedical, and the National Institute for Allergy and Infectious Diseases (NIAID).

Timeframe: 14 days

Population: Per protocol population minus the number of participants with missing observations (4 participants in each Arm/Group).

Clinical course of COVID-19 as a function of Serum Total 25-hydroxyvitamin D concentrations of \<50 ng/mL, 50 to 100 ng/mL and \>100 ng/mL at Day 14, defined as the proportion of subjects in each treatment group with a total score of ≤5 for the selected five COVID-19 symptoms (trouble breathing, chest congestion, dry or hacking cough, body aches and pains, and chills and shivering) using the FLU-PRO Plus© questionnaire. Results were similar for comparisons between treatment groups on Days 7, 14, 21 and 28, and only data for Day 14 is presented.
