Study Description

Brief Summary:

The purpose of this study is to assess innovative treatment methods in patients with adult respiratory distress syndrome (ARDS) as well as those at risk of developing ARDS.

Detailed Description:

BACKGROUND:

ARDS affects approximately 150,000 people in the United States each year. Despite twenty years of research into the mechanisms that cause this syndrome and numerous developments in the technology of mechanical ventilation, the mortality rate has remained greater than 50 percent. In addition to the tragic loss of human life, this condition poses a cost to society because these patients spend an average of two weeks in intensive care units and require multiple high tech procedures. Because of the overwhelming nature of the lung injury once it is established, prevention appears to be the most effective strategy for improving the outlook for those with ARDS.

Basic research has identified numerous inflammatory pathways that are associated with the development of ARDS. Agents that block these mediators prolong survival in animals with lung injury, and a few of them have been tested in human patients. Because of the large number of putative mediators and the variety of ways that their action can be blocked, the possibility for new drug development is almost infinite. This is an exciting prospect, since it envisions the first effective pharmacologic treatment for ARDS. However, preliminary clinical studies have shown conflicting results, and there is an urgent need for a mechanism to efficiently and effectively test new drugs in ARDS. Treatment studies in patients with ARDS are difficult to perform for three reasons. First, the complicated clinical picture makes it difficult to accumulate a large number of comparable patients in any one center. Secondly, there is no agreement on the optimal supportive care of these critically ill patients. Finally, many of the patients meeting study criteria will not be enrolled in study protocols because of the acute nature of the disease process. For these reasons, therapeutic trials in ARDS require multicenter cooperation.

DESIGN NARRATIVE:

This study compared the effect of corticosteroids with placebo in the management of late-phase (greater than seven days) ARDS. The study determined if the administration of the corticosteroid, methylprednisolone sodium succinate, in severe ARDS that was either stable or worsening after seven days, would reduce mortality and morbidity. The primary endpoint was mortality at 60 days. Secondary endpoints included ventilator-free days and organ failure-free days. LaSRS was designed to include 400 patients and began recruiting in the Spring of 1997. In October 1999, the data and safety monitoring board (DSMB) reduced the recruitment target number to 200 patients because the eligible patients were fewer than anticipated.
