1st quarter of 2014 is most likely. That's the same time that large scale production would come on-line. The FDA wants to see this production before approving. Surprisingly, that's the holdup at this point, not the data.
In reading the article I believe that's correct; no drug delivery until 2014. Ramping up full scale production for the drug, which would have FDA oversight, will take time, as well as the regulatory paperwork, which would be substantial for an AA drug. I think AA is a given, and this was a key statement in the article: "She (Jenn McNary) and two other mothers have met twice with top FDA officials this year. In a recent speech, FDA Commissioner Margaret Hamburg said she had had a "powerful meeting" with DMD families "about what needs to be done to get innovative and life-saving medicines to them faster."
Read the article, it's hard for me to believe that so many people know that this drug works and is going to be approved at some point but not that many on board for accelerated approval. They must believe the FDA is totally incompetent. I'm not that cynical and believe that the FDA knows more than they're getting credit for.
