    Sydys Licenses Clinical-Stage Immuno-oncology Assets in ‘spin out’ transaction


    Potential for over A$400M in milestones and royalties


    Prima to receive 9.9% equity in Sydys

SYDNEY, AUSTRALIA and SEATTLE, WASHINGTON - Prima BioMed Ltd (ASX: PRR; NASDAQ: PBMD) (“Prima”) and U.S.-based Sydys Corporation, Inc. (OTC: SYYC) (“Sydys”), today announced an agreement through which Sydys will license Prima’s CVac™ immuno-oncology program and oversee its future development.

Sydys Corporation (www.sydyscorp.com) is a publicly traded New York company that has been repurposed as a clinical stage biotechnology company in order to develop the CVac assets. Under the terms of the agreement, Sydys will license Prima’s CVac related assets, including manufacturing protocols, clinical data from Phase I and Phase II trials, patents and know-how. Prima will also sell certain assets including some equipment and inventory to Sydys. Dr Sharron Gargosky, the former Chief Technical Officer of Prima who has overseen the development of CVac since 2010, will also transition to Sydys as a consultant to continue the development of CVac. Marc Voigt, Prima’s CEO, will join the Sydys Board of Directors soon after closing.

In this spin out transaction Prima will receive a 9.9% equity stake in Sydys at the time of closing as consideration for the assets being transferred. Given the significant capital requirements for conducting clinical trials, no upfront payment will be received however should CVac be successfully commercialized, Prima could receive over A$400 million (US$293 million) in development, regulatory and commercial milestone payments payable for achievement of set commercial sales targets, in addition to low single digit royalties on sales.

Marc Voigt, Prima’s CEO, commented: “Following extensive discussions with a number of third parties, we have reached what we consider to be an entrepreneurial solution which we believe best positions CVac for clinical success and, hopefully, commercialization. Importantly, this partnership continues the CVac program development without further resource commitment from Prima, while providing the potential for considerable future milestone and royalty payments over time. The ongoing development will be contingent on further successful capital raising for subsequent trials but we are confident that the Sydys team has the ability and connections in the US to undertake this program.”

Experienced biotech entrepreneur Joseph Hernandez, the newly appointed Executive Chairman of Sydys Corporation, added: “We believe that the CVac program has tremendous potential, supported by encouraging Phase I and II data in ovarian cancer patients. Studies conducted to

date have reinforced CVac’s strong safety profile and demonstrated meaningful improvements in both overall survival and progression-free survival compared to standard-of-care. We look forward to further evaluating the efficacy of CVac with the goal of bringing the treatment to this underserved patient population.”

About CVac

CVac therapy is a personalized immunocellular therapeutic that has been investigated for the treatment of epithelial cancers. CVac stimulates the patient’s own immune system to target and destroy tumours. It has been investigated in multiple Phase I and Phase II studies with positive results.

Development highlights for CVac include:


    Completion of a randomized Phase II trial that identified epithelial ovarian cancer patients in second remission (CR2) as the target CVac patient population


    CR2 patients receiving CVac have experienced a clinically meaningful improvement in overall survival (OS), as indicated by final data analysis. These data demonstrated median OS of standard of care patients of 25.53 months, while the CVac arm had not reached a median at 42 months (HR=0.17)


    CR2 patients receiving CVac experienced a clinically significant improvement in progression free survival (PFS) of greater than 12.91 months, compared with a PFS of 4.94 months (HR=0.32) for the standard-of-care

CR2 for ovarian cancer is a high unmet medical need; CVac has obtained Orphan Designation for the treatment of ovarian cancer by both the FDA and EMA and Fast Track Designation with the FDA.
