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 769 participants were randomly assigned to receive study agent. The analyses (efficacy) was based on the 741 participants who were randomized after the study was restarted.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In November 2011, due to stability issue with the batch of the intravenous (IV) drug (130 mg Ustekinumab) sponsor temporarily suspended dosing of participants with ustekinumab. Later study was restarted with 90 milligram per milliliter (mg/ml).
