so in this case an interim point which is
about a year before the the entirety of
the trial was complete um the um the
data were were looked at by
statisticians unblinded and they could
see that there was a a significant
difference between the the control group
and the treated group and therefore it
would be unethical to continue to have a
third of the patients receiving just a
sham injection therefore the trials
discontinued now everybody goes on the
drug because there was already
significant uh data that was good enough
to to uh hopefully convince the FDA
