Alnylam is eligible to receive from Arrowhead milestone payments and royalties on sales of product resulting from the license. In addition, Alnylam has received a license from Arrowhead to utilize their Dynamic Polyconjugate (DPC) delivery technology for an RNAi therapeutic product. Alnylam expects to deploy this technology for an undisclosed target in its “Alnylam 5x15” pipeline which is focused on genetically defined targets and diseases. Arrowhead is eligible to receive from Alnylam milestone payments and royalties on sales of product resulting from the license. No additional financial details were disclosed.

“We view Arrowhead’s DPC technology as a promising emerging delivery approach, with the potential to complement our existing delivery platform which currently includes lipid nanoparticles and our siRNA conjugate platform,” said Laurence Reid, Ph.D., Senior Vice President and Chief Business Officer of Alnylam. “In addition, by granting Arrowhead a license for their HBV program, we are enabling their efforts with access to Alnylam intellectual property which we believe is critical for the development and commercialization of RNAi therapeutics. We look forward to continuing to work with Arrowhead, who is already a partner and licensee of Alnylam.”

“This license from Alnylam is an important step for us as we expand our pipeline to include our first DPC-enabled candidate targeting hepatitis B,” said Christopher Anzalone, Ph.D., President and CEO of Arrowhead. “With over 350 million carriers world-wide, HBV represents a large underserved medical need, and one that RNAi and DPCs are well-suited to address. We are also very pleased to grant Alnylam the first commercial license to our DPC technology for one of their genetically defined disease targets. We believe DPCs represent one of the most promising delivery approaches for the systemic delivery of RNAi therapeutics, and we look forward to a close collaboration to help Alnylam bring a DPC-enabled candidate to the clinic.”
