Study Summary

This trial will assess the safety and effectiveness of SGT-003, an IV infusion, in treating Duchenne muscular dystrophy in children ages 4-8. All participants will be monitored for 5 years.

Who is the study for?
The INSPIRE DUCHENNE trial is for young boys with Duchenne muscular dystrophy. Cohort 1 includes ages 4 to under 6, weighing less than 18 kg and able to walk unaided. Cohort 2 will be ages 6 to under 8, weighing less than 30 kg. Participants must not have used certain other treatments for DMD or been in another study recently.Check my eligibility
What is being tested?
This study tests SGT-003 gene therapy given through an IV infusion once. It's divided into two age groups dosed one after the other, with a long-term follow-up of five years to check safety and effectiveness.See study design
What are the potential side effects?
While specific side effects are not listed here, gene therapies like SGT-003 can potentially cause immune reactions, including responses against the virus vector or newly produced proteins, as well as general symptoms such as fever or fatigue.
