ACRIN 6690 Protocol-Specific Application A Prospective, Multicenter Comparison of Multiphase Contrast Enhanced CT and Multiphase Contrast-Enhanced MRI for Diagnosis of Hepatocellular Carcinoma and Liver Transplant Allocation Introduction The ACRIN 6690 trial: “A Prospective, Multicenter Comparison of Multiphase Contrast-Enhanced CT and Multiphase Contrast-Enhanced MRI for Diagnosis of Hepatocellular Carcinoma and Liver Transplant Allocation” represents an opportunity for transplant centers to participate in a multicenter study investigating CT and MRI imaging in the HCC transplant population. The success of this trial will rely heavily on a site’s multidisciplinary team of radiologists, transplant surgeons, hepatologists and pathologists and their interaction with the ACRIN 6690 project team to enroll participants and carry out the protocol’s imaging and correlative pathology examinations. Specifically, the ACRIN 6690 trial will evaluate multiphase contrast-enhanced CT and MRI to establish the respective performance characteristics of these modalities to accurately detect, diagnose, and stage hepatocellular cancer in patients with chronic liver disease. Eligible study participants are patients newly listed on the United Network for Organ Sharing (UNOS) transplant waiting list with HCC-exception points (points assigned based on the patient’s liver cancer diagnosis). Participants are required to undergo multiphasic contrast-enhanced imaging with CT and MRI; within 30 days of the standard of care imaging trial participants will undergo complementary imaging (if initial diagnosis was made on CT, then MRI or if initial diagnosis was made on MRI, then CT). Subsequently, participants will undergo imaging with both modalities scheduled in accordance with the 90-day intervals required for cyclical update of the HCCexception points with UNOS. The additional research imaging exams are included in the case reimbursement from ACRIN. Should local ablative therapy occur for treatment of one or several liver cancers, post-ablation imaging will be obtained a month after completion of therapy and then at aforementioned regular intervals to assess the ability of imaging to detect residual or recurrent disease after such local ablative therapy. Enrollment This study will enroll a total of 440 participants and will be open to all UNOS accredited liver transplant centers in the United States. The United States is divided currently into 11 transplant regions, which vary in area and number of organ transplant procedures. ACRIN plans to enlist a sufficient number of centers from the various regions to accomplish a sample which is representative of the relative distribution of transplant activity in HCC patients in the US. Historic UNOS data are used for benchmarking to determine regional accrual quotas. Participation ACRIN will review the interest from the regional areas and communicate back to each site if they will be asked to participate. This protocol specific application (PSA) serves both to facilitate discussion among site investigators and support staff about the site’s potential to successfully carry out this protocol and to document the site’s capabilities for review by the ACRIN Institutional Participation Committee. Case Reimbursement ACRIN will provide case reimbursement for this trial. This is a per case rate that will be provided based on accruing a patient to the trial and conducting the serial timepoint imaging per protocol. The reimbursement will be as follows: Each case will be reimbursed a “base” case rate of $3,750. This is meant to cover the complementary baseline imaging, a complementary post ablation image, data management, pathology and general data support costs. For each 90-day imaging update timepoint, an additional $1,000 will be issued for the case. Overall, the per patient case rate is dependent upon how long the patient remains on the waitlist, but all patients, if maintained on the trial to explant, will receive a minimum of $3,750. Please complete the following application in electronic format. This will expedite the processing of the application and help maintain correct information on file. E-mail completed applications to [email protected]. If you have any questions about the application, please contact project manager Donna Hartfeil at [email protected] or 215-717-2765.

Personnel 1. Multidisciplinary Trial Team Radiologist: The radiologist for the trial will typically be someone from the body imaging group who normally works with the transplant team and/or is involved in the interdisciplinary tumor board/transplant committee. This person would support the trial by identifying potential participants, consenting the patients, and coordinating schedules for imaging. This person will be a critical success factor for a site’s participant enrollment. Name of Lead Radiologist Physician (mandatory): Telephone: Fax: E-mail: Name of Research Nurse/Coordinator Working with Radiology (optional): (Note: At least one Research Nurse/Coordinator must be identified) Telephone: E-mail: Transplant Surgeon(s): The support of surgeons and their staff to identify potential participants, assist with the consent process, and coordinate schedules will be a critical success factor for a site’s participant enrollment. Name of Transplant Surgeon (mandatory): Telephone: E-mail: Name of Research Nurse/Coordinator Working with Surgeon (optional): Telephone: E-mail: Name of Additional Physician (optional): Hepatologist Telephone: Surgeon Medical Oncologist E-mail: Name of Research Nurse/Coordinator Working with Physician (optional): Telephone: ACRIN 6690 1.16.14 E-mail: Page 1 of 9 ACRIN 6690 Protocol-Specific Application A Prospective, Multicenter Comparison of Multiphase Contrast Enhanced CT and Multiphase Contrast-Enhanced MRI for Diagnosis of Hepatocellular Carcinoma and Liver Transplant Allocation Of the physicians listed above, please indicate who will serve as the site principal investigator, or if this role will be shared? Please also indicate, of the Research Nurse/Coordinator personnel listed above, who will serve as the lead contact? B. Site Requirements 1. Pathology Participants will undergo imaging scheduled in accordance with the 90-day intervals required for cyclical update of the HCC-exception points with UNOS. The goal is to have imaging data from both CT and MRI available which is less than 90 days old when transplantation/explantation occurs. Results from this last imaging time point will be used for direct correlation with explant pathology analysis. The reference standard for the trial will be the systematic pathologic examination of the liver explant, as described in Section 9.0 of the protocol. Therefore, it is essential to review the protocol procedures and information with a pathologist at your center who has an interest in liver pathology and typically works with the liver transplant team in context with explant pathology examinations and liver biopsies. An established interdisciplinary working relationship is ideal for this trial and will facilitate data correlation and exchange. Please confirm that your site can perform the protocol pathology requirements and provide the name and contact information of the pathologist who will coordinate the tissue and data review. Can your site carry out the pathology requirements (section 9.0 of the protocol)? Yes No Name of Pathologist: Telephone: E-mail: Does your site have an IRB-approved pre-existing tissue or serum bank for future review/research? Yes No If yes, approximately how many HCC-MELD patients have pre-existing tissue or serum banked at your site? Is the collection of tumor markers, such as (CA 19-9) standard of care at your site? Yes No 2. Information Technology Infrastructure Each participating site is required to submit all acquired CT and MRI images of study participants to the ACRIN core laboratory. The preferred image transfer method is via TRIAD OA, a software application that includes a rich client and a site server (DICOM file cache). ACRIN provides support for installation of the triad APPLICATION on a suitable site computer(s) of choice. Such computer(s), that reside on the same local area network (LAN) as the acquisition scanner or PACS, can then be set up as a DICOM destination for the purpose of this study. TRIAD then allows “push”-type transfer of the trial related studies directly to the ACRIN server. Alternatively, image can be transferred to the ACRIN central archive by inserting a CD or DVD in the drive of a PC with the TRIAD rich client installed. The TRIAD software anonymizes, encrypts and applies lossless compression to the images before they are transferred to the ACRIN image archive in Philadelphia. ACRIN 6690 1.16.14 Page 2 of 9 ACRIN 6690 Protocol-Specific Application A Prospective, Multicenter Comparison of Multiphase Contrast Enhanced CT and Multiphase Contrast-Enhanced MRI for Diagnosis of Hepatocellular Carcinoma and Liver Transplant Allocation Will your site grant the necessary firewall permissions to transfer electronic image files from a TRIAD server at your site to ACRIN’s image archive via the Internet? If yes, please indicate if your site has a PC available with the following specifications to support the TRIAD software: Operating System Windows XP Pro, Windows 2000 Server SP4 and above, and Windows 2003 server Access to the Internet: Internet Explorer A 100 GB hard drive is preferred At least 512 GB RAM Ability to view PDF documents Software utilities required to run image transmission software: o Windows Installer 3.1 o Microsoft NET framework 2.0 o MDAC Type 2.8 o MS SQL 2005 Express Yes No Yes No Please contact the ACRIN TRIAD help desk to arrange the installation of the TRIAD software prior to first accrual. ([email protected]) or by phone at 215-940-8820) Other options for image submissions include using a secured file transfer protocol (sFTP) to submit images to a specified location on the ACRIN server; or submitting images via a CD shipped to the ACRIN imaging core laboratory. Plain/hard copy films will not be accepted. If you are unable to support the use of TRIAD at your site, is your site capable of submitting the CT or MRI images via sFTP or CD/DVD? Yes No C.

Yes No 4. CT or MRI Scanner Qualification (Trial Specific) ACRIN qualification of the CT and MRI scanner to be used on this study is also required prior to enrollment of study participants. This is separate from the ACR accreditation requirement noted above. Qualification for this trial will include the submission of anonymized, retrospective, multiphase MR and CT liver images from patients with cirrhosis and HCC at each site. Each site interested in participation in this trial must submit anonymized DICOM images of three complete exams of each modality, multiphasic contrast-enhanced CT and MRI, of (non-protocol) patients with HCC obtained during the previous 12 months on the scanners intended for use in the trial. The CT and MRI data need not have been obtained in the same patient. The images will be reviewed centrally for technical adequacy (timing of contrast enhancement relative to image acquisition, biologic motion, MRI artifacts, etc). Feedback will be provided back to the sites. The application and instructions are available on the ACRIN 6690 protocol-specific Web page (click on the “Imaging Materials” section) at www.acrin.org/6690_protocol.aspx. D. Participant Recruitment ACRIN will work closely with the participating sites to support participant enrollment. Accrual success will significantly depend upon well planned coordination and effective communication among the transplant team, imaging personnel and the study participant. This study will enroll a total of 440 participants and will be open to all UNOS accredited liver transplant centers in the United States. The United States is divided currently into 11 transplant regions, which vary in area and number of organ transplant procedures. This study will not enroll equal numbers from all regions but rather, the quota of participants recruited from a particular UNOS region will be kept proportional to the overall contribution of the region to the national total of patients transplanted with HCC-exception points. Historic UNOS data are used to determine the regional quotas. 1.
