AGAMREE® helped improve how muscles work and move in boys with Duchenne

How AGAMREE was studied

In a clinical study lasting up to 48 weeks, boys treated with AGAMREE showed improvements in muscle function during the first 24 weeks compared with placebo. The study had 2 back-to-back periods: an initial 24-week period with 121 boys, followed by a second 24-week period that included 114 boys from the first period. During the second 24-week period, improvements in muscle function with AGAMREE 6 mg/kg once daily were maintained through 48 weeks of treatment. The study was not designed to compare treatments beyond 24 weeks.

At 24 weeks, boys taking AGAMREE 6 mg/kg daily: 

Time to Stand Velocity

How fast boys could stand up from lying on their back, measured by how many rises (completed stands) they could complete per second

6-Minute Walk Test

Distance boys could walk in 6 minutes

Time to Run/Walk 10 Meters Velocity

How fast boys could run or walk 10 meters, measured by how many meters they could travel per second

*Compared with placebo.

Results with AGAMREE were maintained over time.

These changes in how muscles work and move were maintained through 48 weeks of treatment in boys who continued AGAMREE 6 mg/kg once daily.

“Starting Eli on AGAMREE when he was 3 was the best choice we could have made for him. His muscle is precious, and time is muscle.”
