Phase 4
Completed
Conditions
Covid19
Interventions
Other: Placebo
Registration Number
NCT04636086
Lead Sponsor
University of Liege
Brief Summary

The objective of the study is to evaluate the clinical efficacy and safety of vitamin D supplementation in hospitalized patients with COVID-19.

Detailed Description

Phase IV, interventional, randomised, double blind, placebo-controlled and parallel study to evaluate the clinical efficacy and safety of vitamin D supplementation in hospitalized patients with COVID-19.

Patients will participate in the study for a maximum of 9 weeks, which includes an up to 6-week treatment period and a maximum of 3-week follow-up period.

A total of 100 (50 in each group) patients will be randomized in the study and will either receive the test treatment or the placebo treatment.
