Pimavanserin Ph. 3 Trail Fails; Downgrade to Sell; TP Reduced to $1.50 or
Cash

* What is New - ACAD reported negative Ph. 3 trial results for
Pimavanserin in Parkinson's Disease Psychosis (PDP). The study failed to
hit its primary endpoint of mean change from baseline in antipsychotic
efficacy.

* Ph. 3 Trial Design - Trial enrolled 298 pts randomized to 10mg or 40mg
Pimavanserin, or Placebo, over 6 weeks. The primary endpoint was
antipsychotic efficacy measured by SAPS. For successful trial, at least
one Pimavanserin arm had to hit p<.025 vs. placebo.

* Primary Efficacy Endpoint - Mean reported change from baseline on SAPS
at 6 weeks for Pimavanserin 10mg, 40mg and placebo was -5.8, -6.7 (ns),
and -5.9, respectively.

* Cash - ACAD held $66M in cash at June 30. Expects its cash balance to be
greater than $40M at year-end.

* Changes to the Model - See note for changes to the model.

* Conclusions - We are reducing our target price to $1.50 per share, or 1x
cash value, from $4.50. We believe these negative trial results will make
it almost impossible for Pimavanserin to secure FDA approval in PDP.
