CAMBRIDGE, Mass. & BRISBANE, Calif.--(BUSINESS WIRE)--Biogen Inc. (Nasdaq: BIIB) and Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicine company, today announced that they have executed a global licensing collaboration agreement to develop and commercialize ST-501 for tauopathies including Alzheimers disease, ST-502 for synucleinopathies including Parkinsons disease, a third undisclosed neuromuscular disease target, and up to nine additional undisclosed neurological disease targets. The companies will leverage Sangamos proprietary zinc finger protein (ZFP) technology delivered via adeno-associated virus (AAV) to modulate the expression of key genes involved in neurological diseases.

As a pioneer in neuroscience, Biogen will collaborate with Sangamo on a new gene regulation therapy approach, working at the DNA level, with the potential to treat challenging neurological diseases of global significance. We aim to develop and advance these programs forward to investigational new drug applications, said Alfred Sandrock Jr., M.D., Ph.D., Executive Vice President, Research and Development at Biogen.

There are currently no approved disease modifying treatments for patients with many devastating neurodegenerative diseases such as Alzheimers and Parkinsons, creating an urgency for the development of medicines that will not just address symptoms like the current standards of care, but slow or stop the progression of disease, said Sandy Macrae, CEO of Sangamo. We believe that the promise of genomic medicine in neuroscience is to provide a one-time treatment for patients to alter their disease natural history by addressing the underlying cause at the genomic level.

Sangamos genome regulation technology, zinc finger protein transcription factors (ZFP-TFs), is currently delivered with AAVs and functions at the DNA level to selectively repress or activate the expression of specific genes to achieve a desired therapeutic effect. Highly specific, potent, and tunable repression of tau and alpha synuclein has been demonstrated in preclinical studies using AAV vectors to deliver tau-targeted (ST-501) and alpha synuclein-targeted (ST-502) ZFP-TFs.

The combination of Sangamos proprietary zinc finger technology, Biogens unmatched neuroscience research, drug development, and commercialization experience and capabilities, and our shared commitment to bring innovative medicines to patients with neurological diseases establishes the foundation for a robust and compelling collaboration, said Stephane Boissel, Head of Corporate Strategy at Sangamo. This collaboration exemplifies Sangamos commitment to our ongoing strategy to partner programs that address substantial and diverse patient populations in disease areas requiring complex clinical trial designs and commercial pathways, therefore bringing treatments to patients faster and more efficiently, while deriving maximum value from our platform.

Under the terms of the collaboration, Biogen has exclusive global rights to ST-501 for tauopathies including Alzheimers disease, ST-502 for synucleinopathies including Parkinsons disease, and a third undisclosed neuromuscular disease target. In addition, Biogen has exclusive rights to nominate up to nine additional undisclosed targets over a target selection period of five years. Sangamo will perform early research activities, costs for which will be shared by the companies, aimed at the development of the combination of proprietary CNS delivery vectors and ZFP-TFs targeting therapeutically relevant genes. Biogen will then assume responsibility and costs for the investigational new drug-enabling studies, clinical development, related regulatory interactions, and global commercialization.

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.

Conference call

Sangamo will host a conference call at 8:00 a.m. ET tomorrow, Friday, February 28, which will be open to the public via telephone and webcast. During the conference call, Sangamo will discuss the collaboration, review financial results for the fourth quarter and full year 2019, and provide a business update. The conference call dial-in numbers are (877) 377-7553 for domestic callers and (678) 894-3968 for international callers. The conference ID number for the call is 4609858. Participants may access the live webcast via a link on the Sangamo website in the Investors and Media section under Events and Presentations. A conference call replay will be available for one week following the conference call on Sangamos website. The conference call replay numbers for domestic and international callers are (855) 859-2056 and (404) 537-3406, respectively. The conference ID number for the replay is 4609858.
