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.
