Once the FDA has the info they are looking for, it's then up to them to decide. It may take a week, 2 weeks or more. They have been reviewing the info already so i don't think it will take long. Then there is the question of how long it will take to approve an AA filing should the FDA allow it. Some say it could take 6 months, some believe quicker. Remember, SRPT has to ensure that its manufacturing capabilities are in order.
