I recall recently reading about a clinical trial which was aborted recently on moral grounds - the treatment being tested was so effective they couldn't justify continuing to administer placebos. (Annoyingly, I can't find either the article or the name of the drug at the moment)
Since you seem to have a good understanding of the process, what would happen in this case? I'd guess something along the lines of "We've already established statistical significance, we can proceed", but wouldn't that potentially weaken the study of things like side-effects or long-term use?
Do testing protocols have provisions for this sort of thing?
