The SSRE analysis was conducted on the highest dose (108mg twice daily) in the trial after 50% of the initial targeted trial enrollment, or 80 patients, completed the six weeks of treatment. Based on the SSRE analysis, it was recommended that the CORAL trial should continue as planned to maintain the pre-specified conditional power of 80% or greater. The other two potential pre-specified outcomes of the SSRE analysis were an increase in the sample size or futility.
