DWORF gene therapy for heart failure and muscular dystrophy

Official title: Developing DWORF gene therapy to treat heart failure and muscular dystrophy

Funded at Cincinnati Childrens Hosp Med Ctr · NIH-11241166 · Data updated 2026-11-12

This project is testing a gene therapy that raises levels of a small protein called DWORF to help adults with heart failure or muscular dystrophy improve heart and muscle function.

Who could benefit from this research

Could help

Adults with heart failure or genetic forms of muscular dystrophy that affect heart and skeletal muscle would be the likely candidates for this approach.

Less likely to help

People whose condition is not driven by calcium handling problems, young children, or those who cannot receive viral gene therapy may not benefit from this approach.

What this research studies

If you have heart failure or muscular dystrophy, researchers aim to develop a one-time gene treatment that delivers the DWORF gene to heart and skeletal muscle using a harmless viral carrier. They will optimize the viral delivery, dosing, and safety in laboratory studies and animal models before any human use. The team will measure whether DWORF improves calcium handling inside muscle cells and protects against muscle damage and weak heart contractions. Work is focused on steps needed to move this approach toward future clinical testing in patients.

Why it matters

Potential benefit: If successful, the therapy could improve heart pumping and reduce muscle degeneration by restoring normal calcium control in muscle cells.

How similar studies have gone: AAV gene delivery has helped other genetic diseases and boosting SERCA activity showed benefit in animal studies, but delivering DWORF is a newer, mainly preclinical approach.
