One way to be first is to launch in a country where there's a culture of cutting corners, widespread censorship and control of media, so any problems could be covered up if necessary.

Another way is to start early and when the data is available, make sure the regulators work to a tight schedule. I'm not sure how thick the pile of data can be from a trial, but I'd be inclined to give the regulators 48 hours to respond with questions after receipt of data.
