Biogen and Sangamo Announce Global Collaboration to Develop Gene Regulation Therapies for Alzheimer’s, Parkinson’s, Neuromuscular, and Other Neurological Diseases

Biogen Inc. and Sangamo Therapeutics, Inc. , a genomic medicine company, announced on February 27yh that they have executed a global licensing collaboration agreement to develop and commercialize ST-501 for tauopathies including Alzheimer’s disease, ST-502 for synucleinopathies including Parkinson’s disease, a third undisclosed neuromuscular disease target, and up to nine additional undisclosed neurological disease targets. The companies will leverage Sangamo’s proprietary zinc finger protein (ZFP) technology delivered via adeno-associated virus (AAV) to modulate the expression of key genes involved in neurological diseases. Sangamo will be responsible for GMP manufacturing activities for the initial clinical trials for the first three products of the collaboration and plans to leverage its in-house manufacturing capacity. Biogen will assume responsibility for GMP manufacturing activities beyond the first clinical trial for each of the first three products. Upon closing of this transaction, Sangamo will receive $350 million comprised of $125 million in a license fee payment and $225 million from the sale of new Sangamo stock, or approximately 24 million shares at $9.21 per share. In addition, Sangamo may receive up to $2.37 billion in other development, regulatory, and commercial milestone payments, including up to $925 million in pre-approval milestone payments and up to $1,445 million in first commercial sale and other sales-based milestone payments. Sangamo will also be eligible to receive from Biogen tiered high single-digit to sub-teen double-digit royalties on potential net commercial sales of products arising from the collaboration. Closing of the transaction is contingent on completion of review under antitrust laws, including the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976 in the U.S.
