  • Research summary

    The DELIVER study is testing an investigational drug called DYNE-251 in boys and male adolescents with Duchenne muscular dystrophy (DMD) with mutations amenable to exon 51 skipping. The DELIVER study is designed to understand if DYNE-251 is safe, what the best dose of DYNE-251 is, and if it can increase muscle dystrophin and improve muscle function. Participants will be in the study for up to 35 months, including multiple scheduled visits to the study site. Approximately 46 participants will be entered into the study globally. There are inclusion and exclusions criteria, and therefore not every patient is eligible.

    In the DELIVER study, a computer will assign a participant to receive either DYNE-251 or placebo, at random, for the first 24 weeks. Neither the participant nor parent or caregiver will know which study treatment will be received for the first 24 weeks. The study doctor and nurse also will not know.

    The placebo is a water and sugar solution that looks like DYNE-251 but contains no active treatment. A placebo is used in a clinical trial to better understand whether an investigational therapy is working and safe. In this study, comparing DYNE-251 to placebo will help doctors determine if any effects seen in your body are due to DYNE-251 or not. All participants on placebo will receive DYNE-251 after 24 weeks.
