About Marina Biotech, Inc.
Marina Biotech is a leading nucleic acid-based drug discovery and development company focused on rare diseases. Our drug discovery platform, the broadest in the sector, allows us to develop compounds which best counter the underlying pathophysiology associated with a specific rare disease. Using this platform, we are developing proprietary single- and double-stranded nucleic acid therapeutics including siRNAs, microRNA mimics, antagomirs and antisense compounds intended to trigger various RNA-based mechanisms of action including RNA interference, microRNA replacement therapy, microRNA inhibition and mRNA translational inhibition, respectively. We believe our chemistry technologies and our comprehensive drug delivery technologies -- which utilize multiple, separate and distinct delivery modalities -- provide us with one of the most unique drug discovery engines for the development of nucleic acid-based therapeutics for rare and orphan diseases. Two of our delivery technologies are currently in human clinical trials, of which one -- SMARTICLES^® -- is the only technology delivering both single-stranded and double-stranded nucleic acid payloads. Currently, we are advancing CEQ508, for which we have received FDA orphan drug designation, in a Phase 1 clinical program for patients with Familial Adenomatous Polyposis. In addition, we are expanding our rare disease focus to include myotonic dystrophy and Duchenne's muscular dystrophy. Our goal is to improve human health through the development of nucleic acid-based compounds and drug delivery technologies that together provide superior therapeutic options for patients.
