Sarepta Therapeutics and Dyno Therapeutics Announce Agreement to Develop Next-Generation Gene Therapy Vectors for Muscle Diseases

05/11/20 7:00 AM EDT

-- Agreement leverages Sarepta’s leadership in gene therapy for neuromuscular and cardiovascular diseases and Dyno’s CapsidMap artificial intelligence platform to design AAV vectors --

CAMBRIDGE, Mass., May 11, 2020 (GLOBE NEWSWIRE) -- Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, and Dyno Therapeutics, Inc., a biotech company applying artificial intelligence (AI) to gene therapy, today announced an agreement to develop next-generation Adeno-Associated Virus (AAV) vectors for muscle diseases, using Dyno’s CapsidMap™ platform.  

AI and machine learning technologies have the potential to deliver enhanced vectors for gene therapies. Dyno’s proprietary CapsidMap platform opens up new ways to identify novel capsids – the cell-targeting protein shell of viral vectors – that could offer improved muscle targeting and immune-evading properties, in addition to advantages in packaging and manufacturing.

“Sarepta’s world-leading gene therapy engine is founded on three pillars: developing a broad portfolio of programs to treat rare diseases; our first-in-class manufacturing expertise; and investment in advancing and further improving the science of gene therapy to help patients in need of more options. To that end, our agreement with Dyno provides us with another valuable tool to develop next-generation capsids for gene therapies to treat rare diseases,” said Doug Ingram, Sarepta’s President and Chief Executive Officer. “By leveraging Dyno’s AI platform and Sarepta’s deep expertise in gene therapy development, our goal is to advance next-generation treatments with improved muscle-targeting capabilities.”

Under the terms of the agreement, Dyno will be responsible for the design and discovery of novel AAV capsids with improved functional properties for gene therapy and Sarepta will be responsible for conducting preclinical, clinical and commercialization activities for gene therapy product candidates using the novel capsids. If successful, Dyno could receive over $40 million in upfront, option and license payments during the research phase of the collaboration. Additionally, if Sarepta develops and commercializes multiple candidates for multiple muscle diseases, Dyno will be eligible for additional significant future milestone payments. Dyno will also receive royalties on worldwide net sales of any commercial products developed through the collaboration.

“This agreement is a major step forward in our plan to realize the potential of Dyno’s AI platform for gene therapies to improve patient health. We are excited to work with Sarepta to create gene therapies with improved properties to address a range of muscle-related diseases,” stated Dyno’s CEO and co-founder Eric D. Kelsic, Ph.D. “The success of the gene therapies developed through this collaboration with Sarepta will rely on AI-powered vectors that allow gene therapies to be safely and precisely targeted to the muscle tissue.”

About CapsidMap™ for Designing AAV Gene Therapies 
By designing capsids that confer improved functional properties to Adeno-Associated Virus (AAV) vectors, Dyno’s proprietary CapsidMap™ platform overcomes the limitations of today’s gene therapies on the market and in development. Today’s treatments are primarily confined to a small number of naturally occurring AAV vectors that are limited by delivery, immunity, packaging size, and manufacturing challenges. CapsidMap uses artificial intelligence (AI) technology for the design of novel capsids, the cell-targeting protein shell of viral vectors. The CapsidMap platform applies leading-edge DNA library synthesis and next-generation DNA sequencing to measure in vivo gene delivery properties in high throughput. At the core of CapsidMap are advanced search algorithms leveraging machine learning and Dyno’s massive quantities of experimental data, that together build a comprehensive map of sequence space and thereby accelerate the discovery and optimization of synthetic AAV capsids.

Dyno’s technology platform builds on certain intellectual property developed in the lab of George Church, Ph.D., who is Robert Winthrop Professor of Genetics at Harvard Medical School (HMS), a Core Faculty member at Harvard’s Wyss Institute for Biologically Inspired Engineering, and a co-founder of Dyno. Several of the technical breakthroughs that enabled Dyno’s approach to optimize synthetic AAV capsid engineering were described in a November 2019 publication in the journal Science, based on work conducted by Dyno founders and members of the Church Lab at HMS and the Wyss Institute. Dyno has an exclusive option to enter into a license agreement with Harvard University for this technology.
