SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Oct 7, 2025--

SonoThera ™, a biotechnology company dedicated to treating the root cause of human diseases by developing the next generation of genetic medicines, today announced it will present new data at the 32 nd congress of the European Society of Gene and Cell Therapy being held October 7-10 in Seville, Spain.

The poster presentation focuses on treating Duchenne Muscular Dystrophy (DMD) with a full-length human dystrophin payload delivered to skeletal, heart and diaphragm muscles using SonoThera’s proprietary RIPPLE TMultrasound-mediated delivery (UMD) technology. The new data demonstrates the ability of RIPPLE TM to enable broad, highly targeted biodistribution of diverse payload formats without size restriction, to enable genetic medicines that can be re-dosed, and which are safe, well-tolerated, and cost-effective.

“Our new data continues to demonstrate the potential of ultrasound-mediated delivery of genetic medicines and its unique capabilities in treating complex diseases like Duchenne Muscular Dystrophy,” said Kenneth Greenberg, PhD, CEO of SonoThera. “In particular, the ability to deliver targeted, full-length human dystrophin to skeletal, heart and diaphragm muscles in a durable, safe, redosable and noninvasive manner shows how UMD can overcome all of the challenges of current gene therapy delivery options. We look forward to sharing these results at this year’s ESGCT congress.”
