Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Subjects were recruited from 68 study centers in the US.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Of the 1001 enrolled, 341 subjects did not qualify for treatment and were exited without exposure to product. The 660 subjects eligible for treatment were randomized (1:1:1) to study drug. This reporting group includes all randomized subjects, as treated.
