Data presented at the 2012 European Congress of Psychiatry showing that
Selincro(TM) reduces total alcohol consumption by two-thirds on average after
six months of treatment

  * Phase 3 data showed that patients treated with Selincro were able to reduce
    their total alcohol consumption by 66% on average after six months of
    treatment
  * Selincro was safe and well tolerated
  * Selincro has significant potential in helping individuals with alcohol
    dependence reduce their alcohol consumption
  * Selincro is the first medicine targeting reduction of alcohol consumption
    and it is currently undergoing regulatory review in Europe
Biotie announced today that its partner H. Lundbeck A/S (Lundbeck) has presented
results from the phase 3 program of Selincro(TM) (nalmefene), an investigational
compound for the treatment of alcohol dependence, at the 20th European Congress
of Psychiatry (EPA) in Prague, Czech Republic. Data from the three placebo-
controlled phase 3 studies (ESENSE 1, ESENSE 2 and SENSE) was discussed during
the symposium. In addition, the ESENSE 1 study was presented as a poster by
Prof. Dr. Karl Mann et al.  Further details of the ESENSE 2 and SENSE studies
will be presented at the Annual Research Society on Alcoholism (RSA) Scientific
Meeting in San Francisco in June."The results presented today reinforce the efficacy and safety of Selincro in
patients with alcohol dependence," said Timo Veromaa, President and CEO of
Biotie. He continued, "Selincro has the potential to transform the way alcohol
dependence is managed by both physicians and patients and we look forward to
working with our partner Lundbeck and the regulators to make this important new
treatment option available in Europe".

Summary of the results from phase 3 program presented at EPA 2012:

All studies were multi-centre, randomized, double-blind, placebo controlled,
parallel group studies of 18 mg Selincro taken as needed in patients with
alcohol dependence according to DSM-IV criteria. Patients were instructed to
take one tablet on each day they perceived a risk of drinking alcohol,
preferably one to two hours prior to the anticipated time of drinking. Medical
advice and support to enhance motivation and adherence were included in all
treatment arms in the studies. No abstinence treatment goal was imposed.

A total of 1,997 patients were randomized in the three studies, 604 patients in
ESENSE 1 (298 on placebo, 306 on Selincro), 718 in ESENSE 2 (360 on placebo,
358 on Selincro), and 675 in SENSE (166 on placebo, 509 on Selincro).

The primary objective of the two identical six month studies ESENSE1 and ESENSE
2 was to evaluate the efficacy of as-needed use of Selincro versus placebo in
reducing the number of heavy drinking days (HDD) and the monthly total alcohol
consumption (TAC) over a period of six months in alcohol-dependent patients. A
heavy drinking day is defined as a day with a consumption of at least 60g
alcohol for men and at least 40g alcohol for women. The primary objective of
SENSE was to evaluate the long-term safety and tolerability of Selincro versus
placebo over a period of 52 weeks in patients with alcohol dependence, as well
as to evaluate the efficacy of Selincro versus placebo at six months.

In all studies a wide range of secondary endpoints were assessed, including the
proportion of responders based on drinking measures, alcohol dependence symptoms
and clinical status, liver function, other laboratory tests and pharmaco-
economic outcomes (not reported here).

In ESENSE 1 and ESENSE 2, Selincro was superior to placebo in reducing the
number of HDDs (p <0.05 in both studies) and TAC (ESENSE 1, p <0.05; ESENSE 2, p
= 0.088) at month 6. In SENSE, Selincro was more effective than placebo (p<0.05)
in reducing the number of HDDs and TAC at the majority of the time points
studied, including 52 weeks, although not at month 6. In all the studies, the
effect of Selincro as measured by HDD and TAC was evident already at month one
and was maintained throughout the treatment period.

In ESENSE 1, the mean number of HDDs decreased from 19 to 7 days/month and the
mean TAC decreased from 84 to 30g/day in the Selincro group at month 6. In the
placebo group, the mean number of HDDs decreased from 20 to 10 days/month and
the mean TAC decreased from 85 to 43g/day at month 6. Further, improvements in
the secondary endpoints Clinical Global Impression and the liver enzymes GGT and
ALAT were larger (p<0.05) in the Selincro group than in the placebo group at
month 6.

In ESENSE 2, the mean number of HDDs decreased from 20 to 7 days/month and the
mean TAC decreased from 93 to 30g/day in the Selincro group at month 6. In the
placebo group, the mean number of HDDs decreased from 18 to 7 days/month and the
mean TAC decreased from 89 to 33g/day at month 6.

In SENSE, the mean number of HDDs decreased from 15 days/month at baseline to 5
days/month at month 6, and further to 3 days/month at one year in the Selincro
group. While the mean TAC decreased from 75g/day at baseline to 22g/day at month
6, and to 16g/day at one year.  In the placebo group, the mean number of HDDs
decreased from 15 days/month at baseline to 6 days/month at month 6, while the
mean TAC decreased from 75g/day at baseline to 27g/day at Month 6, with
essentially no further decreases for both endpoints at one year.

In all three clinical studies the overall safety profile of Selincro was
consistent with observations and data provided in previous studies, resulting in
a total clinical database of more than 3,000 individuals. The most frequent
adverse events included dizziness, insomnia and nausea and these were mild and
transient. The majority of these events had an onset within the first days after
the initial dose, and then decreased with treatment continuation.

About Selincro(TM) (nalmefene)

Selincro (nalmefene) is a small molecule distinct opioid system modulator that
inhibits the reward pathway in the brain that reinforces the desire and craving
for alcohol and other addictive substances. As a result, Selincro removes a
person's desire to continue to drink.

Biotie has licensed global rights to nalmefene to Lundbeck. Under the terms of
the agreement, Biotie is eligible for up to EUR 84 million in upfront and
milestone payments plus royalties on sales from Lundbeck. Biotie has already
received EUR 12 million from Lundbeck. Further milestone payments are expected
on commercial launch of Selincro and on the product reaching certain
predetermined sales. Lundbeck will be responsible for manufacturing and
registration of the product.

Lundbeck submitted a European Marketing Authorisation Application (MAA) for
nalmefene for the treatment of alcohol dependence via the centralized procedure
for regulatory approval in Europe in December 2011.

About alcohol dependence

Alcohol dependence is a disease in which the afflicted person continually craves
alcohol, is unable to limit his or her drinking, needs to drink greater amounts
to get the same effect and has withdrawal symptoms after stopping alcohol use.
Alcohol dependence also has potentially fatal consequences such as liver
cirrhosis and cancer, among others. As a result, this disease is one of the most
serious health concerns in the western world, both socially and economically,
with estimated associated costs to society of at least EUR 200 billion per
annum. It is estimated that in any given year approximately 3.4% of EU citizens
over 15 years of age suffer from alcohol dependence, corresponding to more than
14 million people. Despite this, alcohol dependence tends to be severely under-
diagnosed with only approximately 13% of alcohol dependants receiving treatment,
characterizing it as a large unmet medical need.

Currently, conventional methods of treating alcohol dependence require
abstinence from drinking as a starting point - a high hurdle for an alcohol
dependent patient. There are only a few pharmaceutical compounds that have
received marketing approval to help alcohol dependent patients maintain
abstinence. All these treatments, including psychosocial counseling measures,
cannot prevent patients from relapsing and the long term prognosis remains poor.
There are no approved therapies on the market yet to proactively help curb a
person's urge to drink.
