AbbVie and ADARx Pharmaceuticals Announce Collaboration and License Option Agreement to Develop Next-Generation siRNA Therapies Across Multiple Therapeutic Areas

- Collaboration to leverage AbbVie's expertise in biotherapeutic drug development and commercialization together with ADARx's proprietary RNA technology to advance next-generation siRNA therapies across neuroscience, immunology and oncology , /PRNewswire/ -- AbbVie (NYSE: ABBV) and ADARx Pharmaceuticals, a late clinical-stage biotechnology company developing next-generation RNA therapeutics, today announced a collaboration and license option agreement to develop small interfering RNA (siRNA) therapeutics across multiple disease areas, including neuroscience, immunology and oncology. siRNA represents a class of molecules capable of regulating gene expression and protein production. Unlike traditional modalities such as antibodies and small molecules, siRNA regulates the expression of genes. These molecules are designed to prevent the production of disease-causing proteins by targeting the messenger RNA (mRNA) that encodes for such proteins. The strategic collaboration will leverage ADARx's RNA discovery expertise and proprietary siRNA technology, which has the potential to enable sustained and precise mRNA silencing. AbbVie will contribute its expertise in antibody engineering, antibody drug conjugates (ADCs) and tissue delivery approaches as appropriate, to augment ADARx's discovery efforts. "siRNA is a promising genetic medicine approach for silencing disease-causing genes, but challenges still remain in targeting and delivering siRNA effectively," said Jonathon Sedgwick, Ph.D., senior vice president and global head, discovery research, AbbVie. "We are very pleased to collaborate with ADARx, leveraging their proprietary RNA technology alongside our antibody, ADC, and therapeutic area research and development expertise to bring siRNA forward as a potential novel therapeutic modality alongside our other established approaches. Together, we're committed to developing innovative solutions for difficult-to-treat diseases across neuroscience, immunology and oncology." "This collaboration with AbbVie further validates the differentiated RNA technology that we have developed at ADARx and has the potential to unlock tremendous clinical and commercial potential across multiple disease areas. AbbVie's research and development expertise combined with its global commercial reach make them the ideal strategic collaborator to accelerate these programs for the potential benefit of patients worldwide," said Zhen Li, Ph.D., co-founder, president and chief executive officer of ADARx. "In addition to this strategic collaboration with AbbVie, ADARx continues to advance a deep pipeline of wholly-owned clinical-stage programs that span complement-mediated, cardiovascular and thrombotic diseases and various preclinical discovery programs including in obesity and neurodegeneration." Under the terms of the agreement, ADARx will receive a $335 million upfront payment and will be eligible to receive several billion dollars in additional contingent payments including option-related fees and milestone payments, as well as tiered royalties.
