LEXINGTON, Mass., & BAGSVÆRD, Denmark--(BUSINESS WIRE)--Nov. 18, 2019-- Dicerna™ Pharmaceuticals, Inc. (Nasdaq: DRNA) and Novo Nordisk A/S today announced an agreement to discover and develop novel therapies for the treatment of liver-related cardio-metabolic diseases using Dicerna’s proprietary GalXC™ RNAi platform technology. The collaboration plans to explore more than 30 liver cell targets and may deliver multiple clinical candidates for disorders including chronic liver disease, non-alcoholic steatohepatitis (NASH), type 2 diabetes, obesity, and rare diseases. Dicerna will conduct and fund discovery and preclinical development to clinical candidate selection for each liver cell target, and Novo Nordisk will be responsible for all further development.

The agreement represents a significant investment by Novo Nordisk to secure access to Dicerna’s proprietary GalXC RNAi platform, which complements its existing technology base. The collaboration provides Novo Nordisk with the capability to inhibit hepatocyte targets involved in disease regulation and has the potential to generate a number of clinical development candidates.

“We are excited to collaborate with Novo Nordisk on this broad research and development effort that extends the reach of our GalXC platform to a wide range of liver cell targets and maximizes our opportunities in serious liver diseases,” said Douglas M. Fambrough, Ph.D., president and chief executive officer of Dicerna. “Our efforts will benefit from Novo Nordisk’s expertise in cardio-metabolic diseases and years of experience developing and commercializing innovative therapies worldwide, which will help us advance novel RNAi treatments for underserved patient populations.”

The agreement enables each company to co-develop and co-commercialize product candidates discovered under the collaboration. Novo Nordisk will lead programs targeting cardio-metabolic disorders and other indications with Dicerna having the option to opt into two programs during clinical development. Dicerna retains rights to initiate two new orphan liver disease programs for which Novo Nordisk can opt in. For all co-development programs, the companies will share in the profit/loss of net sales of products consistent with each company’s contribution to co-development costs.

“Through this important collaboration with Dicerna, we gain access to an innovative technology and deep expertise in RNA interference,” said Marcus Schindler, senior vice president of Global Drug Discovery in Novo Nordisk. “Dicerna is the ideal partner to discover and develop molecules for targets that may yield multiple potential treatments across disease areas such as diabetes, obesity, cardiovascular, and NASH. We will work closely together to unlock the true potential of treating a range of diseases using RNAi therapies, for the benefit of patients.”

Under the terms of the agreement, Dicerna will receive:

• An upfront payment of USD 175 million.
• A USD 50 million equity investment in Dicerna at a premium.
• USD 25 million annually during each of the first three years of the collaboration, contingent on Dicerna delivering RNAi molecules for a defined number of targets.
• Up to USD 357.5 million per target in development, regulatory, and commercialization milestone payments, plus tiered royalties on product sales ranging from the mid-single-digits to mid-teens.

The transaction is subject to the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and other customary conditions.

About Dicerna's GalXC™ RNAi Technology Platform
Dicerna’s proprietary RNA interference (RNAi) technology platform, called GalXC™, aims to advance the development of next-generation RNAi-based therapies designed to silence disease-driving genes in the liver and other tissues. Liver-targeted GalXC-based compounds enable subcutaneous delivery of RNAi therapies that are designed to bind specifically to receptors on liver cells, leading to internalization and access to the RNAi machinery within the cells. The GalXC approach seeks to optimize the activity of the RNAi pathway so that it operates in the most specific and potent fashion. Compounds produced via GalXC are intended to be broadly applicable across multiple therapeutic areas, including both liver and non-liver indications.

About Dicerna^TMPharmaceuticals, Inc.
Dicerna™ Pharmaceuticals, Inc., is a biopharmaceutical company using ribonucleic acid (RNA) interference (RNAi) to develop medicines that silence genes that cause disease. The company is applying its proprietary GalXC™ technology to develop potent, selective, and safe RNAi therapies for treatment of rare diseases, chronic liver diseases, cardiovascular diseases, neurodegenerative diseases, pain, and viral infectious disease. Dicerna aims to treat disease by addressing the underlying causes of illness with capabilities that extend beyond the liver to address a broad range of diseases, focusing on target genes where connections between gene and disease are well understood and documented. Dicerna intends to discover, develop, and commercialize novel therapies either on its own or in collaboration with pharmaceutical partners. Dicerna has strategic collaborations with Novo Nordisk A/S, Roche, Eli Lilly and Company, Alexion Pharmaceuticals, Inc., and Boehringer Ingelheim International GmbH.
