Impossible! Hope you are not confusing Priority Review with AA?
In order for AA approval to happen in the next three months, SRPT should have submitted the NDA three months ago (if NDA is designated Priority Review) or 7 or8 months ago if NDA was designated a standard Review. Both did not happen so AA approval cannot happen in next three months. Hope this clarifies your question.
Hey reg, the FDA has already seen most of this data, I'am sure someone there has been looking at it for months. They may just approve this the minute the NDA is filed. Nothing says they can't. The data is certainly good enough especially when you consider NO toxicity. Drugs have been approved for cancer in the middle of the trial.
