Professor Macfarlane has NOT violated any protocol for this trial. Professor Macfarlane has made logical inferences from observation and experience that subjects that are responding much better than normal over time and mention that they have minor dizziness at times are most probably taking the active drug in this case Anavex 2-73 than just taking a placebo. That is NOT a violation of the blinding protocol of the trial. That is a logical inference from an experienced health care provider.
