Morphotek, Inc. Announces an Agreement With Biocare Medical, LLC to Develop and Commercialize A Diagnostic Kit for Detection of Mesothelin in Malignant Tissues

Exton, PA, December 16, 2015

Morphotek®, Inc., a subsidiary of Eisai Inc., announced today that it entered into a second collaboration and license agreement with Biocare Medical, LLC (Biocare) to develop and commercialize an immunohistochemical (IHC) diagnostic kit utilizing Morphotek’s proprietary monoclonal antibody to specifically detect mesothelin with Biocare’s intelliPATH™ Automated Stainer. The agreement provides Biocare with a worldwide non-exclusive license to develop, manufacture and commercialize an IHC kit for detection of mesothelin on formalin-fixed paraffin-embedded (FFPE) tumor tissues. This is the second such agreement between Morphotek and Biocare; the first a license agreement signed in 2011 to develop kits, now commercially available, to detect folate receptor alpha in malignant tissues.

“We are excited to continue the development of diagnostic kits utilizing our proprietary reagents in cooperation with Biocare and their innovative IHC platform technology,” stated Daniel J. O’Shannessy, Ph.D., Head of Translational Medicine and Diagnostics at Morphotek. “This is our second agreement with Biocare and we look forward to developing a kit that can detect the tumor-associated cell-surface protein, mesothelin, to improve prognostic and therapeutic options for patients in support of our human healthcare mission.”

Mesothelin is a cell-surface protein that is over-expressed in a variety of cancers including mesothelioma, non-small cell lung adenocarcinoma, pancreatic and ovarian carcinoma. Studies have found its expression variable among different cancer types; therefore, diagnostic assays that can identify patients with mesothelin-positive cancers may enable better diagnosis and treatment options for patients affected with mesothelin-expressing cancers. Mesothelin is the target of Morphotek’s investigational therapeutic candidate, amatuximab, which is currently being assessed in a randomized, double-blind clinical trial in patients with newly diagnosed malignant pleural mesothelioma. Further information on the clinical study can be found at, study number NCT02357147.
