Biotie reports top-line data from clinical study with nepicastat (SYN117) in
post-traumatic stress disorder

Biotie today reported top-line data from a Phase 2 study evaluating its dopamine
beta hydroxylase inhibitor nepicastat (SYN117) in combat veterans suffering from
post-traumatic stress disorder (PTSD). The study was funded by the U.S.
Department of Defense and conducted as an Investigator-initiated study in the
United States using clinical trial material supplied by Biotie.

Treatment with nepicastat was not effective in relieving PTSD-associated
symptoms when compared to placebo. Nepicastat was generally well tolerated.

"We are disappointed with the results of this trial and will work with the study
investigators to analyze and understand the data in more detail before deciding
on next steps with nepicastat in PTSD", said Timo Veromaa, President and CEO of
Biotie. "Independent of these results, we will continue to develop nepicastat in
cocaine dependence in partnership with the U.S. National Institute of Drug Abuse
(NIDA). We expect the first patients to be enrolled into a Phase 2 study in Q1
2013."

ABOUT THE STUDY (ClinicalTrials.gov identifier: NCT00659230)

The completed Phase 2 study was a randomized, placebo-controlled, double-blind
study conducted in 100 combat veterans fulfilling diagnostic criteria for PTSD.
It was conducted at 4 VA Medical Centers in the United States, with Dr. Lori
Davis from Tuscaloosa VA Medical Center as the Principal Investigator.

The subjects were randomized in a 1:1 ratio to receive either 120 mg/day
nepicastat or matching placebo for 6 weeks under double-blind conditions.
Thereafter, subjects could continue on open-label study drug for an additional
8 weeks.

Efficacy was evaluated with the Clinician-Administered PTSD Scale (CAPS); the
primary efficacy variable was the CAPS hyperarousal subscale (CAPS-D). Safety
and tolerability were assessed with standard methods, including adverse event
inquiries and laboratory analyses.

ABOUT NEPICASTAT (SYN117)

Nepicastat is an orally administered, potent and selective inhibitor of the
enzyme dopamine beta hydroxylase (DBH), the enzyme responsible for the
conversion of dopamine into norepinephrine. The compound has demonstrated
potential as a treatment for cocaine dependence and PTSD.

Nepicastat was licensed from Roche in 2007.
