Novo Nordisk A/S has acquired a clinical-stage humanized monoclonal antibody and transthyretin amyloidosis (ATTR) program in a deal that could bring Prothena Corp. plc potential development and sales milestone payments of up to $1.2 billion. Also in the agreement, Dublin-based Prothena brings in $100 million in up-front and near-term clinical milestones payments as Novo gets full worldwide rights to the intellectual property and related rights of Prothena’s ATTR amyloidosis business and pipeline.
