I'm trying to recall, but I do believe this is the only study I've come across where the placebo group came out on top. However, I have to agree with Scott, that this can only be viewed as a failed study. The inclusion of an active comparator that also failed implicates the methodology, rather than the investigative drug. It's useful for generating new hypotheses, but worthless insofar as answering any.
