@avidresearch I don't know anything about the $BHVN external control or how it was constructed, so I can't comment. $QURE is sourcing its ECA from a very large, independent and well-regarded natural history study, which works in its favor, I think. Legit, even if doesn't entirely eliminate the risks. On the other side of the spectrum, toally illegitimate, for instance, you have a company like $NWBO that made up its own ECA AFTER knowing its drug failed and then cherry-picked studies to fake a positive result. Pure garbage. ECAs remain controversial. Hopefully we learn something from $BHVN and $QURE.
