INTERIM REPORT ON BIOTIE THERAPIES CORP. JANUARY 1 - JUNE 30, 2007


BIOTIE THERAPIES CORP. STOCK EXCHANGE RELEASE
August 10, 2007

January - June 2007 in brief

In May 2007 the H. Lundbeck A/S licensing agreement entered into
force on worldwide rights for nalmefene, excluding North America,
Mexico, UK, Ireland, Turkey, and South-Korea.

In May 2007 Biotie revised its outlook for 2007 and announced that
2007 financial result is expected to improve compared to year 2006,
but the company expects to report a loss for the full year 2007.

In June 2007 Biotie withdrew its UK national marketing authorisation
application on nalmefene to enable a centralised EU-wide registration
procedure in due course.

EUR 4 million was booked as revenue in the second quarter of 2007 of
the total execution fee of EUR 12 million paid by Lundbeck to Biotie.
EUR 2 million was paid on the license entering into force in May,
2007 and EUR 10 million was paid on signing in November, 2006.

The net income in January - June, 2007 was EUR 1.6 million positive
(in 2006 EUR -4.4 million). Cash flow from operating activities was
EUR -2.9 million (EUR -3.8 million in 2006).

The company's liquid assets amounted to EUR 30.2 million as at June
30, 2007 (at June 30, 2006, EUR 5.0 million).


Drug development programs

Nalmefene program

Biotie announced on May 23, 2007 that the licensing agreement entered
into force on H. Lundbeck A/S worldwide rights for nalmefene,
excluding North America, Mexico, UK, Ireland, Turkey, and
South-Korea.

In June 2007 Biotie withdrew the UK national marketing authorisation
application on nalmefene in its alcoholism indication to enable a
centralised EU-wide registration procedure in due course. A
centralised EU-wide registration procedure is not feasible if the
product already has a granted or a pending national marketing
authorisation in the EU.

To maximise nalmefene's potential in the treatment of alcoholism
Biotie and Lundbeck have jointly decided to seek marketing
authorisation simultaneously in all 27 EU member states via the
centralized procedure. To this end, Lundbeck plans to further
strengthen the existing nalmefene registration dossier in its
alcoholism indication with additional phase III clinical studies
before submitting the marketing authorisation application. The
studies are expected to start in 2008.

The license agreement terms were amended to reflect the planned
additional Lundbeck investment to strengthen the registration dossier
for the centralized procedure. Under the terms of the amended
agreement, Biotie received an execution fee of EUR 12 million, of
which EUR 10 million was paid on signing in November 2006 and EUR 2
million was paid on the license entering into force in May 2007. In
total, Biotie is eligible for up to EUR 80 million in upfront and
milestone payments plus royalty on sales. Biotie will participate in
financing some of the clinical development costs.

The June 22, 2007 issue of "Alcoholism: Clinical and Experimental
Research", a leading journal in addiction therapies, featured a
scientific article on nalmefene in the treatment of patients with
alcohol problems. The featured study describes the results of the
company's phase III clinical study that was conducted in Finland and
enrolled about 400 patients with impaired control over their alcohol
drinking. According to the results, targeted use of nalmefene during
the 28 weeks of treatment decreased heavy drinking statistically
significantly. The reduction in the number of heavy drinking days
compared to placebo was about 32%. The company has communicated the
main results of this study first in 2003.



VAP-1 antibody program

The company is ready to start the first phase I clinical trial with
its fully human VAP-1 monoclonal antibody, pending final regulatory
approval. A separate stock exchange release will be issued at the
start of the study.

The intellectual property rights of the VAP-1 antibody program were
further strengthened by filing a new patent application in the EU and
US in April, 2007.

In November 2006, Biotie and F. Hoffmann La Roche (Roche) signed an
option agreement for Biotie's fully human antibody program targeting
Vascular Adhesion Protein-1 (VAP-1) in inflammatory diseases.
Inhibiting VAP-1 reduces inflammation by regulating the migration of
leukocytes, or white blood cells, to inflamed tissues.


Pre-clinical programs

Pre-clinical programs (VAP-1 SSAO small molecule inhibitor program
and alfa2beta1 integrin inhibitor program) progressed as planned. The
intellectual property rights of the alfa2beta1 integrin program were
further strengthened by filing a new patent application in the EU and
US in April, 2007. In the recombinant heparin program the company
continued to look for a partner to finance the future development of
the program.


Revenues

Revenue for the reporting period January - June 2007 consists of

quarter of 2007 of the execution fee of EUR 12 million paid by
Lundbeck to Biotie. The rest of the EUR 12 million is expected to be
recognized as revenue against clinical development costs in
2007-2009. Of the EUR 12 million, EUR 10 million was paid on signing
in November 2006 and EUR 2 million was paid on the license entering
into force in May 2007. The revenue for the reporting period January
- June, 2007 was in total EUR 5.2 million.

Finnish Industry Investment Ltd (Business identity code 1007806-3)
has informed the company the holdings of Finnish Industry Investment

The holdings of Finnish Industry Investment Ltd constitute 8.702.189
shares, i.e., 9.72 % of the voting rights and share capital in Biotie

Biotie gained knowledge on April 4, 2007 of the following
notification under Chapter 2, Section 9 of the Finnish Securities
Market Act regarding a change in holdings on March 30, 2007:

The aggregate holding of Pequot Healthcare Fund, L.P., Pequot
Healthcare Offshore Fund, Inc., Premium Series PCC Limited - Cell 32,
Pequot Diversified Master Fund, Ltd., Pequot Healthcare Institutional
Fund, L.P. and Pequot Healthcare Emerging Markets Fund, Ltd.

IFRS and Accounting principles

The interim report has been prepared in accordance with IAS 34,
Interim Financial Reporting. Biotie has applied the same accounting
principles as in the closing of year 2006.

This interim report is unaudited.


Risks and Risk Management

Biotie's strategic risks are related to the technical success of the
drug development programs, regulatory issues, the strategic decisions
of its commercial partners, ability to obtain and maintain
intellectual property rights for its products, validity of its
patents, launch of competitive products and the development of the
sales of its products. For example, even though the commercialisation
and collaboration agreements on the company's product development
projects have been concluded, there can be no assurance that the
contracting partner will act in accordance with the agreement, the
authorities will approve the product under development or the
approved product will be commercialised. The development and success
of the company's products depends on third parties.

The operational risks include dependency of key personnel, assets and
dependency on partners' decisions.


Future outlook


Of the execution fee of EUR 12 million paid by Lundbeck to Biotie
approximately EUR 6-7 million will be booked as revenue in 2007 and
approximately EUR 5-6 million is expected to be booked as revenue in
2008-2009.

Biotie's total revenue in IFRS reporting for 2007 is expected to be
approximately EUR 8-9 million, and the operating costs will increase
to a somewhat higher level for 2007 than in 2006.

Biotie 2007 financial result is expected to improve compared to year
2006, but the company expects to report a loss for the full year
2007.

The company is ready to start the first phase I clinical trial with
its fully human VAP-1 monoclonal antibody, pending final regulatory
approval. A separate stock exchange release will be issued at the
start of the study.
