Enhanced dystrophin expression in multiple muscle tissues and sustained functional benefit in DMD disease model following single low dose Data presented at American Society of Gene & Cell Therapy Annual Meeting WALTHAM, Mass. – Dyne Therapeutics, a biotechnology company pioneering targeted therapies for patients with serious muscle diseases, today announced data demonstrating enhanced dystrophin expression in multiple muscle tissues and significant improvement in muscle function in a preclinical model of Duchenne muscular dystrophy (DMD) following treatment with the company’s FORCE™ platform. The findings were highlighted in a poster presentation at the American Society of Gene & Cell Therapy (ASGCT) 23rd Annual Meeting. “Targeting therapeutics directly to muscle tissue has been an enormous challenge for the industry for years. These exciting data reinforce our confidence that Dyne’s FORCE platform can overcome this challenge and effectively deliver transformational therapies for DMD and other serious muscle diseases,” said Joshua Brumm, president and CEO of Dyne. “We are focused on advancing our programs to the clinic, where we believe they will translate into life-changing benefits for patients.” Dyne’s FORCE platform targets the TFR-1 receptor, which is highly expressed on the surface of muscle cells, enabling targeted delivery of a disease-modifying therapeutic payload directly to skeletal, cardiac and smooth muscle tissue. In DMD, the FORCE platform delivers exon-skipping antisense oligonucleotides to muscle cells to enable expression of a more complete, functional dystrophin protein and halt the severe muscle degeneration that characterizes DMD. Key findings presented at ASGCT include: “We’re excited to showcase the power of the FORCE platform to deliver redosable, titratable and highly targeted exon-skipping therapies,” said Romesh Subramanian, Ph.D., Dyne’s chief scientific officer. “ASO uptake across muscle tissue types — including the quadriceps, diaphragm and heart — is far more robust with the FORCE platform. Importantly, we have shown that this uptake results in both increased dystrophin expression and clear functional benefits in a validated DMD disease model. Those benefits were observed following a single low dose and sustained for at least a month post-treatment.” Along with DMD, Dyne is advancing programs in myotonic dystrophy type 1 (DM1) and facioscapulohumeral muscular dystrophy (FSHD).
