ASCEND Study

Insmed Gene Therapy is conducting a study, titled ASCEND, to test the safety of INS1201 in 2-, 3-, and 4-year-old ambulatory boys with genetically confirmed Duchenne muscular dystrophy (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.

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

ASCEND is a first-in-human experimental research study designed to test the safety of INS1201.

The study will include boys aged 2 to <5 years

INS1201 is given as one-time IT injection into the fluid-filled space around the spinal cord

The effect of INS1201 will be assessed from needle biopsy data and physical function tests

The study will last approximately 2 years with an extended follow-up period totaling 5 years
