1 MINT study Principal Investigator: Charles E. Cox, M.D. Co Investigators: Stefan Glück, M.D.

2 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 Oct 2013

3 MammaPrint: 70-gene profile prognostic and predictive tumor analysis Will patient benefit from chemotherapy? TargetPrint: Gene expression of ER/PR/HER2 Centralized lab confirmation of receptor status Will patient benefit from hormonal treatment? BluePrint: 80-gene molecular subtyping profile Basal, Luminal, and HER2 subtypes Which therapy works best? TheraPrint: Gene expression of 56 genes Potential markers for prognosis and therapeutic response Potential therapy options saved for the future Breast Cancer Symphony Suite

4 pCR rate of MammaPrint and BluePrint in previous neo-adjuvant studies

5 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.

6 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.

7 MINT; Nodal staging

8 Study Design Flowchart Core Needle Biopsies Sample placed in RNA Retain, send to Agendia Full Genome Array* not successful Patient ineligible Patient information & informed consent TAC CRF 1 baseline Surgery including nodal staging CRF 2 surgery * (Including diagnostic commercial testing for Symphony Breast cancer Suite) Central slide pathology review TC ddAC/FEC100, paclitaxel or docetaxel TCH Full Genome Array* successful HER2- HER2+ T H/FEC H HER2+

9 Neo-adjuvant therapy For HER2 negative patients: TAC chemotherapy TC chemotherapy Dose Dense AC or FEC100 followed by paclitaxel or docetaxel chemotherapy For 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.

10 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

11 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

12 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.

13 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 Pathology Attn: MINT Trial Bruce B. Downs Blvd MDC 11 Tampa, FL 33612

14 Procedures for Sending Slides APPENDIX III Pathology Worksheet for Core/Incisional Biopsy Please send the following, and complete the form below: One H&E section of tumor ER immunohistochemical stain PR immunohistochemical stain HER2 immunohistochemical stain or FISH/CISH/SISH report 10 unstained sections on positively-charged glass slides (If ER, PR, and/or HER2 studies not available, please send an additional 10 unstained sections on positively-charged glass slides) Questions to be completed on worksheet: 1. Laterality a. Left breast b. Right breast 2. Location a. UOQ b. LOQ c. UIQ d. LIQ 3. Time in formalin a. ≥ 6 to ≤ 48 hours b. Other

15 Procedures for Sending Slides APPENDIX IV Pathology Worksheet for Post-Neoadjuvant Specimens Please send the following, and complete the form below: Two representative blocks of tumor, or 15 unstained slides on positively charged glass slides Copy of final pathology report (including gross description) 1. Specimen a. Lumpectomy/partial mastectomy b. Total mastectomy c. Skin-sparing, nipple-sparing total mastectomy d. Nipple-sparing total mastectomy e. Modified radical mastectomy f. Other 2. Residual tumor a. Grossly identified i. Dimensions: ____ x ____ x ____ cm ii. Percent gross necrosis: b. Not grossly identified * i.Fibrotic tumor bed dimensions: ____ x ____ x ____ cm c. Distance from closest margin: ____ * NOTE: If no definitive tumor grossly identified, please submit entire tumor bed sequentially

16 Pathology Guidelines Note: additional guidelines for your pathology are outlined in Appendix II of the protocol.

17 Clinical Report Form Web based data collection/electronic CRF –CRF1; Baseline information –CRF2; After surgery Relatively easy to complete compared to drug trial minutes for CRF1 and 2

18 Accessing the Database Accessing the Database ◦ There is one hyperlink to access all the electronic Case Report Forms (CRFs) https://trials.agendia.com/MINT ◦ You will receive an institution specific site number and password from your Agendia Clinical Research Manager. Institution:
