Simvastatin Effect on the Incidence of Acute Lung Injury/Adult Respiratory Distress Syndrome (ALI/ARDS)

Acute Lung Injury Clinical Trial

Official title: Simvastatin Effect on the Incidence of Acute Lung Injury/Adult Respiratory Distress Syndrome

Status Withdrawn

Clinical Trial Summary

Acute Lung Injury/Acute respiratory distress syndrome (ALI/ARDS) is a serious and frequently encountered entity in modern ICUs. Sepsis remains the most common cause of ALI/ARDS and carries the worst prognosis. The disease is characterized by an intense inflammatory process. This inflammation plays a major role in the development of gas exchange abnormalities seen in the course of the disease. Statins, primarily used as lipid-lowering agents, are now known to possess anti-inflammatory, antioxidant, antithrombogenic and vascular function-restoring actions. Therefore the investigators propose to determine if Simvastatin may be useful in decreasing the incidence of this deadly syndrome in critically ill patients.

Clinical Trial Description

Patients will be enrolled within 24 hours of ICU admission and randomized to 1 of 2 groups:

Simvastatin or placebo. Patients' management will be entirely left up to the primary team, including the need for daily laboratory and imaging. In addition, there will be no restriction on the use of any medications, as deemed necessary by the primary care physician. The primary endpoint will be the incidence of ALI/ARDS. Secondary efficacy variables will be the number of days without organ or system failure, in addition to the change in IL-6, IL-8, and TNF- α. Treatment will continue until the primary endpoint is reached, the patient discharged from the ICU or the maximum duration of 2 weeks, whichever occurs first. Patients will continued to be followed for a total of 28 days, or until discharged from the hospital, whichever occurs first.

Patients randomized, in a ratio of 1:1 to either Simvastatin 40 mg PO once daily or placebo tablet once daily in a format identical to Simvastatin.

The mortality from ALI/ARDS remains significant. In the absence of effective therapy, prophylaxis in patients at risk is an important goal to achieve. Therefore, if Simvastatin is found to decrease the incidence of ALI/ARDS, it would be a significant advance in the management of this deadly and frequent syndrome.

We have set up a Data Safety Monitoring Board (DSMB) that will closely monitor the progress of the trial (DSMB Charter attached to this application). Any adverse event will be reported directly to the institutional review board (IRB) and DSMB. All adverse events will be reported in the annual review of the protocol. ;
