As mentioned before Christmas, the second steroid we tried, Deflazacort, didn't go over all for Jaxson either.
Last Friday the 3rd and final steroid option arrived- we haven't started quite yet though. There are a few extra things involved with this steroid- it is taken daily and not a weekend dosing and requires us to have a hydrocortisone due to risk of Adrenal Crisis (second post coming related to this)
Agamree (generic name: vamorolone) is a newer steroid medication approved specifically for boys living with DMD. It works similarly to traditional corticosteroids like prednisone or deflazacort by reducing inflammation, protecting muscle fibers and slow disease progression.
How Is Agamree Different? Traditional steroids are effective, but they can come with side effects such as: Weight gain, Behavioral changes, Bone thinning, Growth delay, but Agamree was developed to keep the muscle-protecting benefits of steroids while reducing some of these common steroid-related side effects. This doesn't mean these won't or can't still occur however.
Clinical studies showed it can help maintain muscle strength and function in boys with DMD. It helps protect muscles and slow disease progression, with the goal of offering similar benefits to traditional steroids but with a potentially improved side effect profile.
It sounds so much better than the first two options, so why not go with this one to begin with? Well, not all boys react the same, and many don't do well on this and do the others. It is also newer than the other two, so not as much long term data available. It's actually not even prescribed by our team at Nationwide in Ohio, so we had to go with our local team for this one. Ohio will not prescribe it as they feel it's too new and the data for weekend dosing on Pred or Deflazacort is stronger right now. However, given Jaxsons response to the other two, they were supportive of us wanting to try this option with our local care team. It's overwhelming, nerve-wracking, but trying to be hopeful. We will see how it goes. đđź
