Introducing Wren Laboratories § Founded in 2013, by international authorities in the field of Neuroendocrine Tumors § Developed a multi-gene blood based assay that can accurately measure the biological activity of a NET § Similar Wren assays available for other cancers: colon, lung, ? breast, prostate and melanoma and myeloma § Wren is a CLIA-certified laboratory in Branford, Connecticut § NETest globally available and used in >50 different institutions worldwide § Currently, >10, 000 patients evaluated and peer-reviewed publications in >40 US and European medical and scientific journals

Wren Laboratories: Mission Statement § To develop an easily accessible, real-time molecular genomic tool to facilitate the diagnosis and management of neuroendocrine tumor disease. ? § To ensure that molecular genomic information for a specific person and tumor can be utilized to enhance the NET care pathway. § To enable patients and physicians to establish objective strategies that will positively inform clinical decision-making and add value to currently available imaging techniques. § To enable Liquid biopsy real time information to amplify management of NETdisease

Neuroendocrine Cell Neoplasia § Neuroendocrine cells are sensory cells with ubiquitous distribution throughout the body § Neuroendocrine tumors (NETs) (also called carcinoids), represent abnormal neuroendocrine proliferation § Located in the GI tract, lung and pancreas § Tumor growth ranges from slow to highly aggressive with local invasion, hepatic, lung and bony metastases

Tumor Distribution § The majority (60%) occur in gut and pancreas (GEP) § Substantial

Tumor Distribution § The majority (60%) occur in gut and pancreas (GEP) § Substantial number (>30%) in lung and rectum ~30%) § 60 -70% are metastatic at diagnosis. Average life expectancy after diagnosis: 4 -10 years

In 2003, Prof Irvin Modlin and Dr Mark Kidd were the first to identify the increasing incidence of NET disease . Subsequently more than 50 further publications by others confirmed the observation

This increase in disease represents Increased awareness and more effective Diagnostic Strategies. I. M
