• Collaboration seeks to develop novel treatments for chronic liver diseases, including nonalcoholic steatohepatitis (NASH)

Boehringer Ingelheim and Dicerna Pharmaceuticals (NASDAQ: DRNA), a leading developer of investigational RNA interference (RNAi) therapeutics, today announced that Boehringer Ingelheim has exercised an option to receive exclusive rights to a second hepatic disease target emerging from its research collaboration and license agreement with Dicerna. The collaboration, established in October 2017, aims to discover and develop novel GalXC™ RNAi therapeutics for the treatment of chronic liver diseases, with an initial focus on nonalcoholic steatohepatitis (NASH), a devastating disease for which there is no approved treatment.

The option is the second target under the two companies’ research collaboration and license agreement. Under the terms of the agreement, Boehringer Ingelheim will be responsible for future clinical development and commercialization of the therapeutic target. Dicerna is eligible to receive development and commercial milestone payments, and royalties on worldwide net sales.

“It is extremely gratifying for Boehringer Ingelheim to exercise its option for a second therapeutic candidate from our productive research collaboration,” said Douglas M. Fambrough, President and Chief Executive Officer of Dicerna. “The option exercise underscores the potential of Dicerna’s GalXC technology platform in facilitating the discovery and development of novel RNAi therapies for nonalcoholic steatohepatitis and other chronic liver diseases. We look forward to continued progress and the potential advancement of clinical candidates from our partnership.”

Dicerna and Boehringer Ingelheim selected the target based on its ability to be drugged using Dicerna’s proprietary GalXC technology platform. The GalXC platform uses RNAi to inhibit the expression of disease-causing genes by destroying the messenger RNAs (mRNAs) of those genes. The approach has the potential to treat diseases by silencing previously inaccessible drug targets.

“Boehringer Ingelheim is pleased with the progress of our initial collaboration with Dicerna and based on early findings and our strong relationship, we are expanding our research efforts,” said Clive R. Wood, Ph.D., Corporate Senior Vice President Discovery Research at Boehringer Ingelheim. “Today’s announcement exemplifies our commitment to discovering new therapies for NASH and other chronic liver diseases and advances our research efforts in this priority area.”

NASH is caused by the buildup of fat in the liver, potentially leading to liver fibrosis and cirrhosis. It has an especially high prevalence among obese and diabetic patients and is an area of high unmet medical need. NASH is expected to soon become the most common cause of advanced liver disorders, and it often necessitates liver transplantation.

Dicerna is building a portfolio of research and development programs to advance the treatment of diseases involving the liver, including chronic liver diseases, viral infectious diseases, cardiovascular diseases and rare diseases. The company aims to leverage its proprietary GalXC technology to develop innovative RNAi therapeutics to positively transform the lives of individuals living with these diseases.
