Active Biotech AB and Ipsen to Present Tasquinimod Phase II Overall Survival data at the 2012 American Society of Clinical Oncology Annual Meeting

LUND, SWEDEN and PARIS--(Marketwire - May 18, 2012) - Active Biotech (NASDAQ OMX NORDIC: ACTI) and Ipsen (Euronext: IPN; ADR: IPSEY) will present tasquinimod (TASQ), their prostate cancer drug candidate, at the scientific conference "2012 ASCO Annual Meeting" to be held in Chicago (USA) on 1-5 June 2012. The presentation will provide overall survival (OS) data from the tasquinimod Phase II study in chemotherapy-naïve metastatic castrate resistant prostate cancer (CRPC).

The poster "Tasquinimod and survival in men with metastatic castration- resistant prostate cancer: Results of long-term follow-up of a randomized phase II placebo-controlled trial" A.J. Armstrong, M. Häggman, W.M. Stadler, J.R. Gingrich, V.J. Assikis, J. Polikoff, S.R. Denmeade, D. J. George, C. Andreou, W.R. Clark, P. Sieber, R. Agajanian, L. Belkoff, J-E. Damber, Ö. Nordle, G. Forsberg, M. A. Carducci, R. Pili. will be presented on June 4 at 08:00 am CDT (3:00 pm CET).

The abstract released today, based on 97 events, shows that overall survival after tasquinimod treatment is longer than previously reported in this patient population. Median time to death was 34.2 vs. 30.2 months (tasquinimod vs placebo). A preliminary subgroup analysis using the PCWG2 (Prostate Cancer Clinical Trials Working Group 2) defined criteria showed that median time to death in the bone-metastatic subgroup was 34.2 vs. 25.6 months (tasquinimod vs placebo). The impact of the cross-over design and the imbalance among groups in favor of placebo will be discussed in the presentation.

A global, pivotal, randomized, double-blind, placebo-controlled Phase III study of tasquinimod in patients with metastatic CRPC is ongoing. The aim of the study is to confirm tasquinimod's efficacy on the disease, with radiological Progression Free Survival (PFS) as the primary endpoint and overall survival as secondary endpoint. The study will include about 1,200 patients in more than 250 clinics. Recruitment is proceeding according to plan with top line results expected by the end of 2013.

About tasquinimod

Tasquinimod has a pleiotropic mode of action which includes immunomodulatory, anti-angiogenic and anti-metastatic activity. Today the development of tasquinimod is principally focused on the treatment of prostate cancer. It was announced in December 2009 that the primary endpoint of the Phase II clinical study, to show a higher fraction of patients with no disease progression during the six-month period of treatment using tasquinimod, had been met. Phase II results were published in Journal of Clinical Oncology in September 2011. It was concluded that tasquinimod significantly slowed disease progression and improved Progression Free Survival (PFS) in chemonaïve patients with metastatic castrate-resistant prostate cancer (CRPC), alongside an acceptable side effect profile. Six month progression free proportion of patients for tasquinimod and placebo treatment groups were 69% and 37%, respectively (p < 0.0001), with a median PFS of 7.6 vs. 3.3 months (p=0.0042). Analysis of up to three years safety data from the Phase II study, presented at the EAU February 2012, show that treatment side effects were mild to moderate (~ 5% of AEs grade 3-4), manageable and less frequent after two months of therapy. The adverse events observed included gastrointestinal disorders, primarily observed initially during treatment, fatigue and musculoskeletal pain.

Forward Looking Statement

The forward-looking statements, objectives and targets contained herein are based on the Group's management strategy, current views and assumptions. Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. All of the above risks could affect the Group's future ability to achieve its financial targets, which were set assuming reasonable macroeconomic conditions based on the information available today. Moreover, the targets described in this document were prepared without taking into account external growth assumptions and potential future acquisitions, which may alter these parameters. These objectives are based on data and assumptions regarded as reasonable by the Group. These targets depend on conditions or facts likely to happen in the future, and not exclusively on historical data. Actual results may depart significantly from these targets given the occurrence of certain risks and uncertainties, notably the fact that a promising product in early development phase or clinical trial may end up never being launched on the market or reaching its commercial targets, notably for regulatory or competition reasons. The Group must face or might face competition from Generics that might translate into loose of market shares. Furthermore, the Research and Development process involves several stages each of which involve the substantial risk that the Group may fail to achieve its objectives and be forced to abandon its efforts with regards to a product in which it has invested significant sums. Therefore, the Group cannot be certain that favorable results obtained during pre-clinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the product concerned. The Group also depends on third parties to develop and market some of its products which could potentially generate substantial royalties; these partners could behave in such ways which could cause damage to the Group's activities and financial results. The Group expressly disclaims any obligation or undertaking to update or revise any forward looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law. The Group's business is subject to the risk factors outlined in its registration documents filed with the French Autorité des Marchés Financiers.
