SLDB Solid Biosciences Inc

Solid Biosciences Inc. (Nasdaq: SLDB), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, will present an oral presentation and six posters and at the American Society of Gene and Cell Therapy (ASGCT) 2024 Annual Meeting, Baltimore, May 7-11.

The data presentations will focus on Solid Biosciences’ research and manufacturing capabilities aimed at advancing the field of gene therapy. They will cover various aspects of adeno-associated vector (AAV) manufacturing, novel capsid development, and non-clinical studies with a particular emphasis on the company's lead SGT-003 program.

"We are excited to share our latest scientific findings and advancements at the ASGCT Annual Meeting," said Bo Cumbo, President and Chief Executive Officer at Solid Biosciences. "Our presentations underscore our commitment to developing innovative therapies that address unmet medical needs in neuromuscular and cardiac diseases. We look forward to engaging with the gene therapy community and advancing the field together."

The presentations will feature advancements in gene therapy manufacturing, featuring novel mechanisms to enhance AAV production and refine purification methods. Additionally, innovative approaches in vector biology will be presented, leveraging in silico modeling for AAV vector design and showcasing capsid modifications for improved cardiac tissue targeting. Highlights from non-clinical studies of SGT-003 also will be shared, including findings on microdystrophin expression and functional efficacy in mouse models.

The presentations will cover key areas of Solid Biosciences' research and development initiatives, including:
