Why Is the Extended Window Controversial and What Happened With the FDA?

The ECASS 3 trial was an RCT of IV-rtPA in the window of 3-4.5 hrs after onset of stroke symptoms. It was conducted in Europe. The European regulatory bodies have endorsed tPA for that window, but the FDA has not. Listen to two national experts in stroke discuss the trial and the meaning of the endorsement or lack thereof. This podcast is a must for acute stroke practitioners!

I watched the video on ECASS-III and you mentioned the controversy in this time window. However, there was no mention of Alper et al reanalysis in the BMJ_EBM that questioned the results? Can you comment? https://ebm.bmj.com/content/25/5/168
