Regulus Therapeutics Forms Strategic Alliance for Discovery, Development and Commercialization of microRNA Therapeutics with AstraZeneca

LA JOLLA, Calif., Aug. 14, 2012 /PRNewswire/ -- Regulus Therapeutics Inc., a biopharmaceutical company leading the discovery and development of innovative medicines targeting microRNAs, announced today that it has entered into a strategic alliance with AstraZeneca to discover, develop, and commercialize microRNA therapeutics for three exclusive targets which are currently in pre-clinical development. These targets are focused on cardiovascular and metabolic diseases and oncology.  

Under the terms of the agreement, AstraZeneca will make a $28M payment which includes an equity investment and an upfront payment to Regulus. 

Regulus and AstraZeneca will collaborate on three microRNA targets, which include Regulus' lead cardiovascular/metabolic disease program targeting microRNA-33 for the treatment of atherosclerosis.

Regulus will lead preclinical development and, if successful, could receive pre-clinical milestone payments.  AstraZeneca will lead and fund the clinical development and commercialization of these programs.

In addition, Regulus could also receive clinical milestones based on the successful development of microRNA therapies in each target area. Regulus is also eligible to receive significant launch and commercial milestone payments and royalties contingent on the successful commercialization of microRNA therapeutic products by AstraZeneca.

Gunnar Olsson, Vice President and Head of AstraZeneca's Cardiovascular & Gastrointestinal Innovative Medicines Unit, said: "MicroRNA therapeutics have the potential to open up innovative and important treatment options for patients and AstraZeneca is pleased to collaborate with Regulus in this new and exciting area. Through this collaboration we will marry Regulus' expertise in the microRNA field with our own internal drug development experience with the goal of bringing new treatment options to patients with atherosclerosis-related disease, metabolic disturbances, cancer and potentially other therapeutic areas of interest to AstraZeneca."

"Regulus is pleased to form another significant strategic alliance on microRNA therapeutics," said Kleanthis G. Xanthopoulos, Ph.D., President and Chief Executive Officer of Regulus Therapeutics Inc. "AstraZeneca is a global, innovation-driven company that we believe can greatly aid our efforts to advance microRNA therapeutics to the clinic and the market. The entire field of RNA therapeutics has been rapidly advancing, reaching significant milestones recently. We are committed to realize the broad utility of these new RNA-based medicines to treat human disease in the future. "

Neil W. Gibson, Ph.D., Chief Scientific Officer of Regulus Therapeutics Inc., added, "We wanted to partner our microRNA-33 program with AstraZeneca due to their excellent track record on developing and commercializing drugs in cardiovascular and metabolic diseases and their commitment to the RNA therapeutic field.  We look forward to growing our strategic relationship with AstraZeneca with additional targets to develop important first-in-class medicines."

About microRNA-33 for Atherosclerosis

Atherosclerosis is the build-up of plaque that occurs when cholesterol and inflammatory cells accumulate in blood vessels. These plaques can rupture, leading to slowing or blockage of blood flow and ultimately resulting in a heart attack or stroke. Scientific research has shown a strong correlation between high cholesterol levels and cardiovascular disease which, according to the Centers for Disease Control, is the leading cause of death in the United States.

Regulus' lead program for atherosclerosis targets microRNA-33, which has a unique mechanism of action for the management of cholesterol levels. The inhibition of microRNA-33 with our anti-miRs promotes reverse cholesterol transport, or RCT, which is the efflux of cholesterol from specific cholesterol-laden inflammatory cells called macrophages in atherosclerotic plaques. Treatment with anti-microRNA-33 in an atherosclerotic mouse model led to reduction in arterial plaque size by 35% (Rayner et al., J Clin Invest. 2011) and treatment in non-human primates increased circulating levels of HDL-C by 50%. By enhancing RCT, anti-miR-33 differs from other emerging therapeutic strategies that focus only on raising HDL-C in circulation.

About microRNAs

The discovery of microRNAs in humans during the last decade is one of the most exciting scientific breakthroughs in recent history.  microRNAs are small RNA molecules, typically 20 to 25 nucleotides in length, that do not encode proteins but instead regulate gene expression. More than 500 microRNAs have been identified in the human genome, and over one-third of all human genes are believed to be regulated by microRNAs.  microRNA expression, or function, has been shown to be significantly altered or dysregulated in many disease states, including oncology, fibrosis and metabolic diseases. In preclinical studies, Regulus has demonstrated that modulating microRNAs can effectively regulate disease pathways and produce therapeutically beneficial effects.
