Astellas Pharma Inc, a global life sciences company committed to turning innovative science into value for patients, and Sangamo Therapeutics, Inc, a genomic medicine company, announced they have entered into a license agreement allowing Astellas to leverage Sangamo’s novel proprietary neurotropic adeno-associated virus (AAV) capsid, STAC-BBB, which has demonstrated potent blood-brain barrier penetration and neuronal transduction in nonhuman primates.
The agreement grants Astellas a worldwide exclusive license to utilize the STAC-BBB capsid for one target, with the right to add up to four additional targets after paying additional licensed target fees to deliver their intravenously administered genomic medicines to treat certain neurological diseases. Astellas stands on the forefront of healthcare change to turn innovative science into value for patients.
Sangamo will receive a $20 million upfront license fee and is eligible to earn up to $1.3 billion in additional licensed target fees and milestone payments across all five potential disease targets, as well as tiered royalties on potential net sales.
Sandy Macrae, CEO, Sangamo, said: “we strongly believe in the potential of STAC-BBB, our industry-leading, intravenously delivered AAV capsid, to overcome the challenges associated with delivering therapies to the central nervous system. This agreement underscores the continued industry interest in our STAC-BBB capsid and reinforces our ongoing commitment to partnering with collaborators who understand its unique potential. We are delighted to license STAC-BBB to Astellas to advance potential treatments for neurological diseases with significant unmet medical needs.”
“Delivering treatments to the brain and central nervous system remains a highly complex challenge in the field of gene therapy. We believe that technologies such as Sangamo’s STAC-BBB capsid could prove critical in helping us deliver effective transformational treatments to patients suffering from serious genetic neurological conditions. We continue to build a world-class gene therapy pipeline and end-to-end discovery, development, manufacturing, and commercial capabilities. This agreement is another example of our commitment to delivering meaningful therapies for patients with genetic diseases”, said Adam Pearson, chief strategy officer of Astellas.
Under the terms of the agreement, Sangamo is responsible for completing a technology transfer related to the STAC-BBB capsid. Astellas is responsible for all research, preclinical and clinical development, regulatory interactions, manufacturing, and global commercialization of the resulting gene therapy products.
