Sarepta Therapeutics, Inc. (NASDAQ: SRPT), the leader in precision genetic medicine for rare diseases, and StrideBio, Inc., a leading developer of novel adeno-associated viral (AAV) based gene therapies, today announced the signing of a collaboration and license agreement to develop in vivo AAV-based therapies for up to eight central nervous system (CNS) and neuromuscular targets.
CAMBRIDGE, Mass. and RESEARCH TRIANGLE PARK, N.C., Nov. 14, 2019 (GLOBE NEWSWIRE) -- Sarepta Therapeutics, Inc., (NASDAQ: SRPT), the leader in precision genetic medicine for rare diseases, and StrideBio, Inc., a leading developer of novel adeno-associated viral (AAV) based gene therapies, today announced the signing of a collaboration and license agreement to develop in vivo AAV-based therapies for up to eight central nervous system (CNS) and neuromuscular targets. Pursuant to the agreement, Sarepta is granted an exclusive license on selected targets to leverage StrideBio’s novel, structure-driven capsid technology, intended to enhance specific tropism to tissues of interest and evade neutralizing antibodies. The parties also plan to focus on strategies intended to address re-dosing challenges in patients who have received AAV-delivered gene therapy. StrideBio will conduct all investigational new drug (IND) enabling research, development and manufacturing for the first four CNS targets, which are MECP2 (Rett syndrome), SCN1A (Dravet syndrome), UBE3A (Angelman syndrome), and NPC1 (Niemann-Pick). Additionally, Sarepta will have an exclusive option to four additional targets based on StrideBio’s capsid technology.
StrideBio possesses an innovative and proprietary platform that is enabled by a deep knowledge of AAV structure and a unique approach to engineering capsids with novel functions, and was co-founded by Mavis Agbandje-McKenna, Ph.D., and Aravind Asokan, Ph.D., leading scientists in the field of AAV biology and gene therapy. StrideBio has created a growing portfolio of novel AAV capsids evolved in non-human primates that show reduced seroprevalence and potential for improved tropism to targeted tissues.
“With our partnership with StrideBio, Sarepta continues to build on its leadership position in gene therapies to treat rare diseases. We are excited to work with StrideBio and access its innovative AAV platform for next-generation capsids,” said Doug Ingram, Sarepta’s President and Chief Executive Officer. “Our partnership with StrideBio expands our research portfolio by up to eight new targets and, through our strategic partnering approach that has our collaborator lead all IND-enabling research and development, ensures that we gain access to new technology and targets while not distracting Sarepta from its near-term priorities.”
“We are very excited to initiate this multi-target collaboration with Sarepta, an established leader in the development and commercialization of genetic medicines,” stated Sapan Shah, Ph.D., Chief Executive Officer, StrideBio. “This partnership will provide significant resources and expertise to enable StrideBio’s continued rapid expansion of our research and manufacturing platform, as well as accelerate the development of AAV gene therapies for multiple rare disease targets. We are looking forward to working together with Sarepta to bring novel treatments to patients as quickly as possible.”
Terms of Agreement
Under the terms of the agreement, StrideBio will be responsible for AAV capsid development, non-clinical development and manufacturing of preclinical candidates to be selected for advancement into clinical studies. The parties will also share early clinical development activities for selected targets, with Sarepta responsible for late stage development and commercialization. A total of four initial targets are specified under the collaboration. StrideBio will receive a $48 million upfront payment in the form of cash and Sarepta stock, in addition to significant future development, regulatory and commercial milestones for the four programs. StrideBio will also receive royalties on worldwide net sales of any commercial products developed through the collaboration. Sarepta has also obtained an exclusive option to expand the collaboration to include up to an additional four targets with an upfront payment of up to $42.5 million along with future downstream milestone payments, while StrideBio has an option to obtain co-development and co-commercial rights to one of the collaboration targets. In addition, Sarepta has made a commitment to invest in StrideBio’s next financing round. Further financial terms were not disclosed.
