Marina Biotech Granted European Claims Covering Bacteria Mediated Gene Silencing

Marina Biotech (OTCQB: MRNA), a biopharmaceutical company focused on the development and commercialization of innovative therapeutics for disease intersections of arthritis, hypertension, and cancer, today announced that the European Patent Office intends to grant the company a patent for Bacteria Mediated Gene Silencing (EP 08768475.9, European Patent 2173875).
The granted claims relate to the company’s tkRNAi technology being utilized in its CEQ508 program that is being developed to treat familial adenomatous polyposis (FAP). Marina’s patent portfolio around tkRNAi and its CEQ508 program includes 14 issued patents worldwide. The claims are broad, and cover a prokaryotic vector comprising a promoter for generating siRNAs. Targets for the siRNA include beta-catenin. The vector can include an invasion factor, and a lysis regulator. An invasive bacterium including the vector is also encompassed. Marina Biotech will continue to expand its development of tkRNAi to cover other therapeutic targets as permitted by the granted patent — including Ras, APC, HER-2, MDR-I, MDR-2, FATP4, SGLUT-1, GLUT-2, GLUT-5, apobec-1, MTP, IL-6, IL-6R, IL-7, IL-12, IL-13, Ra-I, IL-18, p38/JNK MAP kinase, p65/NK-kB, CCL20, Claudin-2, Chitinase 3-like 1, apoA-IV, MHC class I and MHC class II.
“We are excited by the recent positive developments from the CEQ-508 program and looking forward to expand bacteria mediated gene silencing to other therapeutic areas protected by our patent portfolio, including oncology, diabetes, and hyperlipidemia,” stated Dr. Vuong Trieu, Chairman of the Board at Marina Biotech. “This unique ability to orally deliver oligo therapeutics across different species and kingdoms will open up applications not possible with any other delivery platforms.”
