Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
A total of 400 deaths in the two treatment arms at the time of the final analysis will provide 80% power to detect a 33% improvement in median survival in the CG1940 and CG8711 arm (24 months) compared to median survival of 18 months in the docetaxel and prednisone arm. This assumes use of a two-sided log-rank test with an overall alpha level of 0.05. It is assumed that 600 patients in a four-year trial will permit observation of 400 deaths. |
