ASCEND is a study being conducted to test the safety of INS1201 in 2-, 3-, and 4-year-old ambulatory boys with genetically confirmed DMD and the effects of INS1201 on their muscle.

INS1201 is an investigational gene therapy designed to produce a short, but functional, form of the key muscle protein dystrophin that is missing or nonfunctional in children with DMD.

ASCEND Phase I will test the safety of INS1201 in 2-, 3-, and 4-year-old ambulatory boys with genetically confirmed DMD and the effects of INS1201 on their muscle.

To participate in this study, your child must meet these and other criteria:

  • Male at birth
  • 2 years to <5 years of age
  • Can walk unassisted for at least 10 meters
  • Definitive diagnosis of DMD prior to screening based on genetic testing, with mutations in DMD gene between or including exons 18 to 58
  • Can cooperate and perform motor assessments

All other study requirements will be explained in detail by the study staff.

INS1201 is given as a one-time intrathecal (IT) injection of a fixed (not weight-based) dose into the spinal fluid to evaluate the efficiency of a lower amount of adeno-associated virus (AAV) on the ability to get muscle and heart tissue to produce micro-dystrophin.

ASCEND will investigate the safety of INS1201 using this administration and the resulting effect on the targeted muscles.
