European Medicines Evaluation Agency Recommends Orphan Drug Designation for Progen Pharmaceuticals Limited’s PI-88

SYDNEY, Aug. 15 /PRNewswire-FirstCall/ -- Progen Pharmaceuticals Limited today announced that the Committee for Orphan Medical Products (COMP) of the European Agency for the Evaluation of Medicinal Products (EMEA) has adopted a positive opinion recommending the granting of orphan medicinal product designation for PI-88 for the treatment of hepatocellular carcinoma, or primary liver cancer.

The Committee’s orphan medicinal products opinions are submitted to the European Commission for orphan designation determination. The orphan drug designation will become effective upon adoption of this recommendation by the European Commission. This is expected to occur before the end of the third quarter of 2007.

The EMEA’s orphan drug program is designed to promote the development of drugs to treat rare life-threatening or very serious conditions that affect no more than five in every 10,000 people in the European Union (EU). The designation provides EU market exclusivity for up to ten years in the given indication. Other potential benefits include: a reduction in fees associated with various aspects of the regulatory process, including the application for marketing approval, and EMEA guidance in preparing protocols concerning studies relevant for approval.

PI-88 is part of a new class of multi-targeted cancer therapeutics inhibiting both angiogenesis (or tumour promoting) factors such as Vascular Endothelial Growth Factor (FEGF), Fibroblast Growth Factors (FGF) 1 and 2, and heparanase, a degrading enzyme implicated in metastasis (tumour spread). Progen will this year launch a multi-national two-armed, double-blinded placebo controlled Phase 3 trial using PI-88, with the primary endpoint of disease free survival, in patients with post-operative primary liver cancer. The goals of PI‑88 treatment in this population are to reduce disease recurrence, prolong the time to recurrence (known as disease-free survival time) and improve the overall survival time of patients after tumour resection. Additionally, the Company is currently conducting a Phase 2 trial in patients with melanoma, the other indication in which we have received U.S. FDA orphan drug designation, with results from this trial expected during the second half of 2008.

Mr. Justus Homburg, Chief Executive Officer of Progen commented: “While the incidence of primary liver cancer in the European Union is relatively low, with over half a million new cases elsewhere in the world, it is a disease of significant global relevance. We are honored by the Committee’s decision and support in our efforts to develop PI-88 for liver cancer.”
