Failure to Improve the Oxygenation Index Is a Useful Predictor of Therapy Failure in Acute Respiratory Distress Syndrome Clinical Trials.

ABSTRACT:

Objective

Acute respiratory distress syndrome trials powered for mortality require significant resources, limiting the number of evaluable therapies. Validation of intermediate endpoints would enhance the feasibility of testing novel acute respiratory distress syndrome therapies in pilot studies and potentially reduce the frequency of failed large clinical trials. We sought to determine whether a change in the oxygenation index over the first 7 days of acute respiratory distress syndrome could discriminate between therapies likely or unlikely to show benefit in larger clinical trials.

Design

A derivation cohort from three acute respiratory distress syndrome studies was used to estimate the 7-day change in oxygenation index. Receiver operating characteristic curves were used
