I used mitozantrone. Three months, once a month. It was a life saver for me, stopped me from slipping into secondary progressive and I have been stable for five years. Lots of long-lasting side effects however, and as with all of the dmd's, we have to weigh the cost vs the possible outcome. This one worked for me, but didn't do anything for my brother. We are all so different,even if we have the same same genes...

There is another one that has been used for a very long time but I can't remember the name. It is reportedly less effective however.
