Biogen and Neurimmune Announce Option Exercise for Alzheimer’s Disease Investigational Treatment Aducanumab

Biogen and Neurimmune announced that Biogen has exercised its option to further reduce the previously negotiated royalty rates payable on potential future sales of aducanumab, Biogen’s Phase 3 investigational treatment for early Alzheimer’s disease.

Biogen will make a one-time $50 million payment to Neurimmune in exchange for a 5% reduction in the original royalty rates on potential commercial sales of aducanumab, which follows the 15% reduction in royalty rates announced in October 2017. The reduced royalty rates on potential commercial sales of aducanumab will be in the high single digits to low-teens. Biogen licensed the worldwide rights to aducanumab from Neurimmune in 2007.

“Biogen values our collaboration with Neurimmune, and this step is aligned with our amended agreement from 2017,” said Michel Vounatsos, chief executive officer of Biogen. “As we progress our pipeline of candidates for Alzheimer’s disease including aducanumab, we hope that a potential treatment for this devastating and debilitating disease will be realized.”

“At Neurimmune, we are pleased with the continuous progress of our long-term successful collaboration with Biogen”, said Roger Nitsch, chief executive officer of Neurimmune. “This non-dilutive financing supports our growth strategy focused on bringing human-derived antibodies through clinical proof-of-concept in disease areas with high medical need.”
