SYDNEY, AUSTRALIA--(Marketwired - May 25, 2014) - Prima BioMed Ltd (ASX: PRR) (NASDAQ: PBMD) ("Prima", the "Company") is pleased to announce that the Company has received a Notice of Allowance from the United States Patent and Trademark Office (USPTO) for Patent Application 11/561,204 "Compositions for immunotherapy and uses thereof" which protects its CVac™ technology; currently in development for ovarian and pancreatic cancer.

This application protects the method of composition and method of use of Prima's CVac for the generation of a cytotoxic T cell response against the mucin 1 antigen. CVac is a personalised immunotherapy composed of patients' own dendritic cells pulsed with the cancer antigen mucin 1, conjugated to oxidised mannan fusion protein. The pulsed dendritic cells are then reinjected into the patient to stimulate an immune response to the mucin 1 cancer antigen.

Chief Executive Officer Matthew Lehman said that, "The allowance of this key USA patent is a significant milestone. The grant of the USA patent would complete the granting of all pending applications relating to the Company's intellectual property portfolio."
