Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The study started in May 2001 with subjects from Germany. The primary completion date and study completion date occurred in March 2011.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
One subject was discontinued on the study due to the Adverse Event of Vertigo. However, the Termination page of the Case Report Form reflected that the subject withdrew consent. Therefore, the Participant Flow will reflect 3 subjects did not complete the study, while the subjects withdrawing from Adverse Events will reflect 2.
