MINT study
Principal Investigator: Charles E. Cox, M.D.
Co Investigators: Stefan Glück, M.D.
MINT
• MINT I: Multi-Institutional Neo-adjuvant Therapy MammaPrint Project I
• Principal Investigator: Charles E. Cox, M.D. USF, Tampa FL• Co Investigator: Stefan Glück, M.D. UM/Sylvester
Comprehensive Cancer Center University of Miami, Miller School of Medicine FL
• Total of 226 patients; up to 10 institutes in the US• Full genome gene expression profiling Agendia Inc• Central pathology review at USF pathology FL• Timelines; Oct 2011- Oct 2013
MammaPrint: 70-gene profile prognostic and predictive tumor
analysisWill patient benefit from chemotherapy?TargetPrint: Gene expression of ER/PR/HER2
Centralized lab confirmation of receptor statusWill patient benefit from hormonal treatment?BluePrint: 80-gene molecular subtyping profile
Basal, Luminal, and HER2 subtypesWhich therapy works best?
TheraPrint: Gene expression of 56 genes Potential markers for prognosis and therapeutic responsePotential therapy options saved for the future
Breast Cancer Symphony Suite
pCR rate of MammaPrint and BluePrint in previous neo-adjuvant studies
MINT; Study Objectives
• To determine the predictive power of chemosensitivity of the combination of MammaPrint and BluePrint as measured by pCR.
• To compare TargetPrint single gene read out of ER, PR and HER2 with local and centralized IHC and/or CISH/FISH assessment of ER, PR and HER2.
• To identify and/or validate predictive gene expression profiles of clinical response/resistance to chemotherapy.
• To identify possible correlations between the TheraPrint Research Gene Panel outcomes and chemoresponsiveness.
• To compare the three BluePrint molecular subtype categories with IHC-based subtype classification.
MINT; Eligibility Criteria
Inclusion criteria:• Women with histologically proven invasive breast cancer;
T2(≥3.5cm)-T4, N0,M0 or T2-4N1M0• DCIS or LCIS are allowed in addition to invasive cancer at T2 or T3
level.• Age ≥ 18 years.• Measurable disease in two dimensions • Adequate bone marrow reserves, adequate renal function, and
hepatic function • Signed informed consent Exclusion criteria• Patients with inflammatory breast cancer.• Tumor sample shipped to Agendia with ≤ 30% tumor cells or that
fails QA or QC criteria.• Patients who have had any prior chemotherapy, radiotherapy, or
endocrine therapy for the treatment of breast cancer.• Any serious uncontrolled inter current infections, or other serious
uncontrolled concomitant disease.

Neo-adjuvant therapy
For HER2 negative patients:• TAC chemotherapy• TC chemotherapy• Dose Dense AC or FEC100 followed by paclitaxel or
docetaxel chemotherapyFor HER2 positive patients:• TCH chemotherapy• T H followed by FEC H
Dose adjustments• Hematological and non-hematological toxicities should be
managed by treating oncologist as per routine clinical practice.
• Agendia will store remaining tissue from patient samples
• This tissue can be used for future scientific research
• Patients are asked in the patient consent form to provide consent for storage and future research
• Please note: If a patient does not wish to allow their tissue to be used for future research, it is the responsibility of the site to communicate this with Agendia
Future Research – Remaining Tissue
Tissue Collection
• Tissue should be collected by incisional biopsy (when placing port) or via core needle biopsy.
• If the tissue is obtained by incisional biopsy then the tissue sample should be no greater than 3 to 4 mm in thickness and between 8 to 10 mm in diameter.
• Core needle biopsies should be obtained with a 14 gauge or larger needle.
– If a 14 gauge needle is used: 5 cores
– If a 11 gauge needle is used: 4 cores
– If a 9 gauge needle is used: 3 cores
Sending Sample to Agendia
A. Remove large specimen tube from kit and open it.
B. Place large screw cap with small specimen vial on table and open small specimen vial.
C. Place a barcode label from the completed requisition form on to the vial.
D. Place the small specimen vial into the large specimen tube and place the tube into the specimen safety bag.
E. Place the sealed specimen bag into the shipping kit along with the requisition form. IMPORTANT: ensure that the study sticker is affixed to the requisition form.
F. Package the kit into the FedEx shipping pack and attach the pre printed label for shipment to Agendia Inc.
G. Please call Fed Ex for pickup.
Central Pathology Review
• Central pathology review for RCB score will be done at USF Pathology FL
• Representative slides of core needle biopsy, sentinel lymph node biopsies and surgical sample should be send to:
USF PathologyAttn: MINT Trial12901 Bruce B. Downs Blvd MDC 11Tampa, FL 33612
Procedures for Sending SlidesAPPENDIX III Pathology Worksheet for Core/Incisional Biopsy
