MammaPrint, BluePrint, and Full-genome Data Linked With Clinical Data to Evaluate New Gene EXpression Profiles

The FLEX Registry will include all patients with stage I-III breast cancer who have received
MammaPrint and BluePrint testing in any clinical setting. Study arm appendices will specify
treatment arm, inclusion criteria, and number of patients needed. Approximately 2000 patients
from 70-75 US based institutions will be enrolled.

Treatment is at the discretion of the physician adhering to NCCN approved regimens of a
recognized alternative.

Clinical data will be collected and entered online at the time points listed: patient
enrollment, time of treatment, 1 year post-treatment, and 2, 5, and 10 years post diagnosis.

Objectives:

- Create a large scale, population-based registry of full genome expression data and
clinical data to investigate new gene associations with prognostic and/or predictive
value

- Utilize shared registry infrastructure to examine smaller groups of interest

- Generate hypotheses for targeted subset analyses and trials based on full genome data

FLEX is an observational (phase IV) study.

Inclusion Criteria:

- Stage I, II, or III patients who receive MammaPrint, with or without BluePrint testing
(male or female)

- Informed consent form signed on the same day or before enrollment

- New primary lesion

Exclusion Criteria:

- Tumor sample shipped to Agendia with ≤ 30% tumor cells or that fails QA or QC criteria

- Metastatic disease

- Recurrent disease

- Stage 0 disease
