Critical Illness Clinical Trial

Official title: Vitamin D to Improve Outcomes by Leveraging Early Treatment

Status Completed

Clinical Trial Summary

Vitamin D deficiency is a common, potentially reversible contributor to morbidity and mortality among critically ill patients. We conducted a randomized, double-blind, placebo-controlled, phase 3 trial of early vitamin D3 supplementation in critically ill, vitamin D-deficient patients who were at high risk for death. Patients screened as vitamin D deficient (<20 ng/mL) were randomized. Randomization occurred within 12 hours after the decision to admit the patient to an intensive care unit. Eligible patients received a single enteral dose of 540,000 IU of vitamin D3 or matched placebo. The primary end point was 90-day all-cause, all-location mortality.

Clinical Trial Description

Primary Objective: To assess the efficacy and safety of early administration of vitamin D3 (cholecalciferol) in reducing mortality and morbidity for vitamin D deficient patients at high risk for Acute Respiratory Distress Syndrome (ARDS) and mortality.

Primary Hypothesis: Early administration of vitamin D3 (cholecalciferol) will improve all-cause, all-location mortality to day 90 in vitamin D deficient patients at high risk for ARDS and mortality.

Methods: Patients were recruited from the emergency departments (EDs), hospital wards, operating rooms, intensive care unites (ICUs) and other acute care areas of the participating PETAL Network Clinical Centers. Screening included a test for Vitamin D (25OHD) levels using either the hospital's clinical laboratory or an FDA-approved point-of-care device (FastPack IP, Qualigen Inc). Patients screened as vitamin D deficient (<20 ng/mL) were randomized. Half of the randomized patients received an early administration of high-dose vitamin D3 and the other half received a placebo. Both active and placebo products were given orally or via naso/orogastric tube.

Rational: Vitamin D has pleiotropic roles in regulating immune function and maintaining epithelial surface integrity. Strong preclinical data support the protective role of vitamin D in regulating pulmonary inflammation and disruption of the alveolar-capillary membrane that are fundamental to ARDS pathogenesis. ;
