of Directors.

Timo Veromaa, Biotie's President and CEO:

"2010 will be a crucial year in Biotie's history. We expect our partner Lundbeck
to announce top-line data of the ongoing phase III studies with our lead product
nalmefene for the treatment of alcohol dependence. Also, with the positive data
generated in our clinical programs VAP-1 antibody and ELB353, we are now at the
turning point, at which we will start seeking partners in addition to Seikagaku
with whom to continue the development of these programs."

Outlook for 2010

- Biotie will continue supporting its licensing partner Lundbeck in the
development of nalmefene for the treatment of alcohol addiction. Phase 3
clinical data for the ongoing studies is expected towards the end of 2010; a
possible marketing authorization submission in the EU is anticipated in 2011.

- Biotie will continue with the development of its proprietary VAP-1 antibody.
Top-line data from an ongoing study in psoriasis patients is expected in mid
2010. While the rights to the product in Japan, Taiwan, Singapore, Australia and
New Zealand have been granted to Seikagaku, Biotie retains the rights in the
rest of the world and will be looking for additional partnering opportunities.

- Biotie intends to continue active development of ELB 353 for the treatment of
COPD. Further clinical trials are planned and discussions around possible
collaboration opportunities will be started still in 2010.

- Biotie will continue to work together with its partner Pfizer in a discovery
alliance regarding the identification of PDE10 inhibitors for schizophrenia
until June 2010. After that time, Pfizer retains the commercial rights for all
product candidates discovered so far and Biotie is committed to support Pfizer
in all development aspects.

- Biotie is adequately funded to support its ongoing activities well into 2011,
even in the absence of any additional income from new collaboration or licensing
arrangements. Any possible commercial agreements with third parties relating to
its clinical programs might significantly improve its financial position. A
forecast on possible income from future licensing arrangements cannot be
provided reliably.

Biotie Therapies detailed interim report

About Biotie

Biotie is a drug discovery and development company focused on central nervous
system and inflammatory diseases. It has a broad range of innovative small
molecule and biological drug candidates at different stages of clinical and
pre-clinical development. Biotie's products address diseases with high unmet
medical need and significant market potential, including addiction and psychotic
disorders, rheumatoid arthritis, psoriasis and chronic obstructive pulmonary
disease (COPD).

Drug development projects and operations:

Nalmefene, a new treatment paradigm for alcohol dependence. Nalmefene builds on
a novel principle of treating alcohol dependence. Unlike existing therapies, the
treatment with Nalmefene is not aimed at keeping the patients from drinking.
Nalmefene instead removes the desire to drink, thereby controlling and limiting
the intake of alcohol. Nalmefene distinguishes itself by being available as an
oral tablet formulation to be taken on an as needed basis.

Biotie has granted worldwide rights (excluding Korea) for Nalmefene to Lundbeck.
Currently, Lundbeck is undertaking three phase III clinical trials with
Nalmefene for the treatment of alcohol dependence. We expect top-line data from
the ongoing clinical trials to become available towards the end of 2010. Biotie
is participating in financing some of the clinical development costs.

ELB353, an oral PDE4 inhibitor for COPD in clinical development. ELB353 is a
once-daily, oral phosphodiesterase 4 (PDE4) inhibitor with therapeutic potential
in chronic inflammatory disorders, particularly in chronic obstructive pulmonary
disease (COPD), a serious disorder with major unmet medical need.

After the reporting period, Biotie reported that it has successfully completed a
Phase I trial with its orally administered PDE4 inhibitor ELB353. The study
evaluated the safety, tolerability, pharmacokinetic characteristics and
pharmacodynamic effects of repeated oral doses of ELB353 in 48 healthy male
volunteers. ELB353 was generally well tolerated, and no serious or severe
adverse events were reported in any of the study subjects. The pharmacokinetic
characteristics of ELB353 demonstrated its suitability for a once daily dosing
regimen. Robust and statistically highly significant biomarker responses
confirmed the pharmacological activity of well tolerated doses of ELB353 in man.

Vascular Adhesion Protein-1 (VAP-1), a key inflammation receptor. VAP-1 has been
shown to play a key role in inflammatory chronic diseases such as rheumatoid
arthritis, psoriasis and diabetes. Potentially it also plays a role in other
chronic inflammatory diseases for which there is a clear unmet medical need.
Biotie has a vast knowledge and strong intellectual property position around
this target.

VAP-1 function can be blocked by either antibody (biologic) drugs or small
molecule drugs which target the enzyme (SSAO) domain of the receptor. Both
approaches are being pursued by Biotie for various therapeutic indications.

VAP-1 antibody, a high value biologic for inflammatory diseases in clinical
development. Biotie is developing a fully human monoclonal antibody which blocks
VAP-1 function. In January 2010 Biotie reported that it has successfully
completed a clinical trial with the product in rheumatoid arthritis patients,
demonstrating the safety, tolerability, and pharmacokinetics of repeated doses
of intravenously administered antibody in 24 rheumatoid arthritis patients.
Although the study was not designed to enable formal statistical evaluation of
therapeutic activity, in several assessments of treatment effect such as Disease
Activity Score based on 28 joint assessment (DAS28) criteria, American College
of Rheumatology (ACR) criteria, physician's global assessment and erythrocyte
sedimentation rate, responses in higher dose groups were greater than in the
placebo group. Several patients receiving higher doses of BTT-1023 reached an
ACR50 response (i.e. a 50% reduction in their ACR score) during treatment
whereas none of the placebo patients reached an ACR50 response.

A similarly designed clinical study initiated in March 2009 in psoriasis
patients is currently ongoing and results from this study are expected in the
second quarter of 2010.

Biotie has granted a license to Seikagaku Corporation to the rights for the
product for Japan, Taiwan, Singapore, New Zealand, and Australia against up to
USD 16.7 million in milestone payments plus royalties on sales in the territory.

After the reporting period, Biotie announced that it regains all commercial
rights to the VAP-1 antibody except in certain territories in which the product
is licensed to Seikagaku. Roche informed Biotie that it does not intend to
exercise its option to in-license the VAP-1 antibody product for its own
strategic portfolio related reasons. Biotie will continue own development
efforts and seek partners in addition to Seikagaku.

VAP-1 SSAO inhibitors. Biotie is pursuing the development of small molecule
inhibitors of VAP-1 SSAO. Currently the program is at pre-clinical stage. Biotie
has granted options to the program to Roche and Seikagaku (for Japan, Taiwan,
Singapore, Australia and New Zealand). Under the terms of the option agreements,
the parties carry their own costs, but Biotie retains ownership of the developed
compounds until Roche chooses to exercise its option for in-licensing.

Phosphodiesterase 10 (PDE10) inhibitors, a novel treatment paradigm for
schizophrenia. PDE10 is a novel molecular drug target in schizophrenia and
Biotie has shown antipsychotic activity of PDE10 inhibitors in animal models.
Biotie's PDE10 inhibitors are believed to serve the unmet medical need for novel
anti-psychotic drugs with an improved side effect profile and improved efficacy
in schizophrenia.

Biotie and Pfizer are in a discovery alliance to jointly identify novel PDE10
inhibitors. This alliance will end in June 2010. After that, Pfizer retains the
commercial rights for all product candidates discovered until then. So far, the
program has advanced one compound into preclinical development.

Financial review

Revenues: Revenue for the reporting period amounted to EUR 1.2 million (EUR 1.4
million in Q1 2009) and consisted of income from the ongoing research
collaboration with Pfizer as well as periodization of previously received
up-front payments from the licensing agreements the company has in place with
several licensing partners.

In addition, Biotie received EUR 0.2 million (EUR 0.3 million in Q1 2009)
non-dilutive funding under a grant from the central development agency for the
state of Saxony (Sächsische Aufbaubank, SAB).

Financial result: The net loss for the reporting period amounted to EUR 3.7
million (EUR 2.9 million in Q1 2009). Research and development costs for the
reporting period amounted to EUR 3.8 million (EUR 3.9 million in Q1 2009).

Financing: Cash and cash equivalents totaled EUR 15.2 million at the end of the
reporting period (EUR 22.2 million).

The company has invested its liquid assets into bank deposits. Bank deposits
with maturity more than 3 months are reported in "investments held to maturity"
whereas deposits with maturity less than 3 months are reported in the "cash and
cash equivalents".

Biotie has a standby distribution agreement with US fund Yorkville in place.
Yorkville is obliged to subscribe and pay for ordinary no-par Biotie shares up
to a total value of EUR 20 million during the period until September 2012 at
Biotie's discretion (Biotie option). The purpose of this arrangement is to have
an option to secure the financing of Biotie's working capital in the short and
medium term.

Shareholder's equity: The shareholders' equity of the group amounts to EUR -12.6
million (IFRS). Biotie's equity ratio was -46.2 % on 31 March 2010 (-6.9 % on
31 March 2009).

Investments and cash flow: Cash flow from operations was EUR -4.4 million for
January - March (EUR -3.3 million during Q1 2009). The group's investments
during the reporting period amounted to EUR 0.1 million (EUR 0.0 million Q1
2009).

Share capital and shares

Biotie shares are all of the same class and have equal rights. Each share
entitles the holder to one vote at the general meeting of shareholders. All
shares are freely transferable and are quoted on NASDAQ OMX Helsinki Ltd (Small
cap, Healthcare).

Biotie´s share capital is EUR 51,506,678.10 (FAS), the total number of shares is
158,752,560. Of these shares, 463,255 are owned by Biotie Therapies Corp.

Changes in ownership

During the reporting period, the company became aware of one notice of change in
ownership exceeding the disclosure threshold.

Information on notices of change in ownership and a monthly updated list of
Biotie's major shareholders is available on the company's website at
www.biotie.com/investors <http://www.biotie.com/investors>.

Short-term risks and uncertainties

Biotie's strategic risks are predominantly related to the technical success of
the drug development programs, regulatory issues, strategic decisions of its
commercial partners, ability to obtain and maintain intellectual property rights
for its products, launch of competitive products and the development of the
sales of its products. The development and success of Biotie's products depends
to a large extent on third parties. Any adverse circumstance in relation to any
of its R&D programs might impair the value of the asset and thus, represent a
severe risk to the company. Such adverse events could happen on a short term
notice and are not possible to foresee.

The key operational risks of Biotie's activities include the dependency on key
personnel, assets (especially in relation to intellectual property rights) and
dependency on its license partners' decisions.

Furthermore, significant financial resources are required to advance the drug
development programs into commercialized pharmaceutical products. To fund the
operations, Biotie relies on financing from three major sources: income from its
license partners, grant income and raising equity financing in the capital
markets.

Although Biotie has currently active license agreements in place, the
termination of any such agreement would have a negative effect on the short to
medium term access to liquidity for the company. Grants have been historically
available to Biotie at substantial levels. Availability of grants in the future
cannot be guaranteed and this thus poses a potential risk to the income
situation of the group in the future. Currently ongoing grant programs are
available until Q3 2010. The company relies on capital markets to raise equity
financing from time to time. There can be no assurance that sufficient funds can
be secured in order to permit the company to carry out its planned activities.
Current capital market conditions are volatile and it is currently uncertain
whether the company can secure equity financing if and when it needs it, even
though it was successful at doing so in December 2009.

To protect the continuity of Biotie's operations, sufficient liquidity and
capital has to be maintained in the company and its subsidiaries. The group aims
to have cash funds to finance at least one year's operations at all times. The
group can influence the amount of capital by adapting its cost basis according
to the financing available. Management monitors the capital and liquidity on the
basis of the amount of equity and cash funds. These are reported to the Board on
a monthly basis.

This interim financial report has been prepared in accordance with IFRS
recognition and measurement principles, and applying the same accounting policy
as for the 2009 financial statements. The interim report has not been prepared
in accordance with IAS 34, Interim Financial Reporting.
