BOTHELL, WA--(Marketwired - Jun 2, 2016) - Marina Biotech, Inc. (OTCQB: MRNA), a leading nucleic acid-based drug discovery and development company focused on rare diseases, today announcd that J. Michael French, chairman of the board, president and chief executive officer, is resigning effective June 10, 2016 to pursue other opportunities. Current board member, Joseph W. Ramelli, will assume the roles of chairman of the board and acting chief executive officer. The board of directors is currently conducting a search for a new CEO.

"The Board thanks Mr. French for his efforts and leadership of Marina, including the transition of the company from an oligonucleotide therapeutics company to a late-stage therapeutics company, with the pending completion of our proposed agreement with Turing Pharmaceuticals for its late-stage intranasal ketamine program.

About Marina Biotech, Inc.
Marina Biotech is an oligonucleotide therapeutics company with broad drug discovery technologies providing the ability to develop proprietary single and double-stranded nucleic acid therapeutics including siRNAs, microRNA mimics, antagomirs, and antisense compounds, including messengerRNA therapeutics. These technologies were built via a roll-up strategy to discover and develop different types of nucleic acid therapeutics in order to modulate (up or down) a specific protein(s) which is either being produced too much or too little thereby causing a particular disease. We believe that the Marina Biotech technologies have unique strengths as a drug discovery engine for the development of nucleic acid-based therapeutics for rare and orphan diseases. Further, we believe Marina Biotech is the only company in the sector that has a delivery technology in human clinical trials with differentiated classes of payloads, through licensees ProNAi Therapeutics and Mirna Therapeutics, delivering single-stranded and double-stranded nucleic acid payloads, respectively. In addition to these companies, we have also licensed the delivery technology to an undisclosed company developing a gene editing approach to the treatment of human diseases. Our novel chemistries and other delivery technologies have been validated through license agreements with Roche, Novartis, Monsanto, and Tekmira. The Marina Biotech pipeline currently includes a clinical program in Familial Adenomatous Polyposis (a precancerous syndrome) and a preclinical program in myotonic dystrophy. Marina Biotech's goal is to improve human health through the development of RNAi- and oligonucleotide-based compounds and drug delivery technologies that together provide superior therapeutic options for patients. Additional information about Marina Biotech is available at

Recently, Marina announced an agreement with Turing Pharmaceuticals AG under which Marina intends to acquire Turing's intranasal ketamine program. The program has been advanced worldwide with plans for U.S. and international clinical trial sites. The work thus far has predominately been directed at suicidality in post-traumatic stress disorder; a patient population with few, if any, therapeutic options. We believe the early clinical successes of this program combined with broadening acceptance of ketamine as a treatment for neurological and psychiatric diseases, presents a unique opportunity to rapidly move this compound into the U.S. market as early as 2019. In addition, there is some earlier work by academic centers suggesting that intranasal ketamine might be efficacious in patients suffering from certain rare diseases. In addition, the Company will also continue to seek alternatives for its nucleic acid therapeutics assets in order to maximize shareholder value. These alternatives could include the licensing and/or sale of individual nucleic acid chemistry and delivery technologies as well as the sale of the entire drug discovery platform.
