Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
A multicenter trial with 24 sites with enrolled subjects and 23 sites with randomized subjects from 15 Feb 2007 to 17 Jul 2008.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Subjects on stable dose of prophylactic medication entered a 2-week Wash-Out Period followed by a 4-week Baseline Period without any prophylactic medication. Subjects not taking prophylactic medication entered the Baseline Period directly for 6 weeks. Subjects entered a 3-week Titration Period and if completed entered a 14-week Maintenance Period.
