SonoThera Presents New Preclinical Data at MDA 2026 Highlighting RIPPLE™ as an Efficient, Scalable, Nonviral Platform for Full-Length Dystrophin Delivery in DMD

South San Francisco, CA, March 5, 2026 - SonoThera ™, a biotechnology company dedicated to addressing the root causes of disease through next-generation genetic medicines, today announced it will present at the annual Muscular Dystrophy Association (MDA) Clinical & Scientific Conference, being held March 8-11^th in Orlando, Florida.

The oral presentation will highlight SonoThera's proprietary RIPPLE™ (Remote Induction of Pulsed Pressure Lateral to Energy) technology and its ability to enable delivery of genetic payloads encoding full-length human dystrophin. Data demonstrate robust protein expression across affected muscle groups in Duchenne Muscular Dystrophy (DMD) models, including skeletal, cardiac, and diaphragm muscle.

SonoThera has optimized its RIPPLE™ technology across multiple rodent and non-human primate (NHP) models and generated compelling translational data supporting broad, highly targeted biodistribution of diverse genetic payloads-without size constraints. The platform is designed to be redosable, durable, well-tolerated, and scalable, addressing key limitations associated with viral delivery approaches.

"One of the central challenges in DMD gene therapy has been achieving efficient delivery of full-length dystrophin in a manner that is safe, scalable, and redosable," said Ken Greenberg, PhD, CEO of SonoThera. "We believe RIPPLE™ has the potential to address these limitations through a nonviral, noninvasive approach, and we look forward to sharing our latest data with the DMD community at MDA 2026."
