Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
An optional 2-year extension was implemented in this trial through a protocol amendment, which brought the total length of treatment to 4 years. However, some sites did not participate in the 2-year extension, and so considered patients to have completed treatment after 2 years.
