Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A total of 200 healthy volunteers were enrolled at the University of Western Australia in Perth between April 17 and July 31, 2009.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Two of 200 randomized subjects (one in each group) decided not to begin study treatment after enrollment, so only 198 subjects were evaluable for response.
