New gene therapy approach shows promise for Duchenne muscular dystrophy
Researchers at Indiana University developed a new gene therapy for Duchenne muscular dystrophy using a triple-adeno-associated virus vector to deliver a complete dystrophin protein, showing promise in mouse models.

Researchers at the Indiana University School of Medicine have developed a promising new gene therapy for Duchenne muscular dystrophy (DMD), a genetic disorder characterized by the absence of the dystrophin protein, leading to muscle degeneration. The study, published in Nature Communications, showcases a novel triple-adeno-associated virus vector system designed to deliver a complete version of the dystrophin protein to muscle tissues. This approach aims to restore full-length dystrophin, which is crucial for muscle health and function, unlike current therapies that utilize truncated versions of the protein, which do not fully protect muscle integrity.
The research demonstrated significant improvements in muscle tissue and strength in mouse models of DMD, indicating the potential for enhanced therapeutic outcomes compared to existing treatments. Senior author Renzhi Han, a professor of pediatrics, emphasized the need for effective therapies, as current options have not met expectations. Han has filed a provisional patent for the new vector system and is collaborating with the IU Innovation and Commercialization Office to advance the therapy toward clinical application. He is also seeking additional funding to ensure that patients with DMD can access this innovative treatment. The study's findings represent a significant step forward in the quest for effective therapies for DMD, which currently lacks satisfactory treatment options.
