I can certainly understand why you wouldn't want to take it, but they're currently recruiting on at least 4 trials of Pimavanserin, and I think they're currently using it for Parkinsons. From the article it says it was a 2-12 vote with 12 in favor. Hopefully these 4 new trials will give something definitive on the risk. Part of the reason these things take so long. Got to make sure it's not likely to kill us.
The phase 3 trials are large enough and long enough so the data should be more meaningful.
