Summary
The FLEX Registry will be implemented to operate as a large-scale, population based,
prospective registry. All patients with stage I to III breast cancer who receive
MammaPrint® and BluePrint testing on a primary breast tumor are eligible for entry into
the FLEX Registry, which is intended to enable additional study arms at low incremental
effort and cost. FLEX Registry will utilize an adaptive design, where additional targeted
substudies and arms can be added after the initial study is opened.
