A Study of IMMray™ PanCan-d Test for Early Detection of Pancreatic Cancer in High-risk Groups

PanFAM-1 is a prospective, multi-center, investigational study, designed to assess the performance of the IMMray™ PanCan-d test in early detection of pancreatic ductal adenocarcinoma (PDAC) in high-risk populations. Specifically, the IMMray PanCan-d test uses state of the art machine learning algorithms to condense the multiple fluorescence data points generated by the test to a simple yes/no result. Thus, a highly complex statistical model uses the multi-dimensional nature of the test to generate a score, which is called a decision value. The score is compared to the established cut-off value for the test to inform the operator whether the patient sample is positive or negative for PDAC. This study will validate and evaluate the performance of the IMMray PanCan-d test in comparison to standard of care imaging approaches that are currently used in PDAC disease surveillance. Subjects in this study will be recruited from several European and North American research sites that have a PDAC surveillance program or established protocol for monitoring individuals considered to be at a high-risk for developing pancreatic cancer. Any subject that shows disease progression while on-study will be removed from the study to receive standard of care per institutional guidelines. Overall, this study poses minimal risk to subjects. The PanFAM-1 study is an adaptive study design over two approximately 18 month intervals, which are separated by an interim analysis to evaluate diagnostic accuracy of the IMMray PanCan-d test. This study is an observational period in which blood collections from eligible subjects will be evaluated using the IMMray PanCan-d test. Subjects will undergo scheduled imaging assessment and clinical evaluation consistent with the resarch sites' PDAC surveillance program. Subject data derived from the IMMray PanCan-d test during this portion of the study will be delayed from time of initial blood collection until the samples are analyzed. The analysis will compare IMMray PanCan-d test results for each subject to corresponding imaging assessments performed as part of standard of care PDAC surveillance. The study will only proceed to the interventional period if the interim analysis indicates that the diagnostic accuracy of the IMMray PanCan-d test is capable of detecting PDAC in high-risk subjects with the same or better ability as standard of care imaging. If at any time imaging assessments are considered positive for clinical disease then, regardless of IMMray PanCan-d test results, subjects will be managed according to institutional guidelines. All scheduled blood collections for purposes of this study will be halted and subjects will be removed from the study upon confirmation of PDAC.
